This commit adds a new top subcommand "summary" to command type named "type". Currently this command implements three commands: type summary add <format> <typename1> [<typename2> ...] type summary delete <typename1> [<typename2> ...] type summary list [<typename1> [<typename2>] ...] type summary clear This allows you to specify the default format that will be used to display summaries for variables, shown when you use "frame variable" or "expression", or the SBValue classes. Examples: type summary add "x = ${var.x}" Point type summary list type summary add --one-liner SimpleType llvm-svn: 134108

Public API changes: - Completely new implementation of SBType - Various enhancements in several other classes Python synthetic children providers for std::vector<T>, std::list<T> and std::map<K,V>: - these return the actual elements into the container as the children of the container - basic template name parsing that works (hopefully) on both Clang and GCC - find them in examples/synthetic and in the test suite in functionalities/data-formatter/data-formatter-python-synth New summary string token ${svar : - the syntax is just the same as in ${var but this new token lets you read the values coming from the synthetic children provider instead of the actual children - Python providers above provide a synthetic child len that returns the number of elements into the container Full bug fix for the issue in which getting byte size for a non-complete type would crash LLDB Several other fixes, including: - inverted the order of arguments in the ClangASTType constructor - EvaluationPoint now only returns SharedPointer's to Target and Process - the help text for several type subcommands now correctly indicates argument-less options as such llvm-svn: 136504

<rdar://problem/11757916> Make breakpoint setting by file and line much more efficient by only looking for inlined breakpoint locations if we are setting a breakpoint in anything but a source implementation file. Implementing this complex for a many reasons. Turns out that parsing compile units lazily had some issues with respect to how we need to do things with DWARF in .o files. So the fixes in the checkin for this makes these changes: - Add a new setting called "target.inline-breakpoint-strategy" which can be set to "never", "always", or "headers". "never" will never try and set any inlined breakpoints (fastest). "always" always looks for inlined breakpoint locations (slowest, but most accurate). "headers", which is the default setting, will only look for inlined breakpoint locations if the breakpoint is set in what are consudered to be header files, which is realy defined as "not in an implementation source file". - modify the breakpoint setting by file and line to check the current "target.inline-breakpoint-strategy" setting and act accordingly - Modify compile units to be able to get their language and other info lazily. This allows us to create compile units from the debug map and not have to fill all of the details in, and then lazily discover this information as we go on debuggging. This is needed to avoid parsing all .o files when setting breakpoints in implementation only files (no inlines). Otherwise we would need to parse the .o file, the object file (mach-o in our case) and the symbol file (DWARF in the object file) just to see what the compile unit was. - modify the "SymbolFileDWARFDebugMap" to subclass lldb_private::Module so that the virtual "GetObjectFile()" and "GetSymbolVendor()" functions can be intercepted when the .o file contenst are later lazilly needed. Prior to this fix, when we first instantiated the "SymbolFileDWARFDebugMap" class, we would also make modules, object files and symbol files for every .o file in the debug map because we needed to fix up the sections in the .o files with information that is in the executable debug map. Now we lazily do this in the DebugMapModule::GetObjectFile() Cleaned up header includes a bit as well. llvm-svn: 162860

Moving ValueObjectCast over to its own .h/.cpp files instead of sharing ValueObjectDynamic.h/.cpp Removing the IsDynamic() and GetStaticValue() calls, so that they will default to the base class behavior: - non-dynamic - itself as the static value This is in contrast with the previous behavior which could be confusing and could potentially cause issues when using those objects llvm-svn: 166857

#include "lldb/Core/ValueObjectChild.h"
Modified LLDB expressions to not have to JIT and run code just to see variable values or persistent expression variables. Now if an expression consists of a value that is a child of a variable, or of a persistent variable only, we will create a value object for it and make a ValueObjectConstResult from it to freeze the value (for program variables only, not persistent variables) and avoid running JITed code. For everything else we still parse up and JIT code and run it in the inferior. There was also a lot of clean up in the expression code. I made the ClangExpressionVariables be stored in collections of shared pointers instead of in collections of objects. This will help stop a lot of copy constructors on these large objects and also cleans up the code considerably. The persistent clang expression variables were moved over to the Target to ensure they persist across process executions. Added the ability for lldb_private::Target objects to evaluate expressions. We want to evaluate expressions at the target level in case we aren't running yet, or we have just completed running. We still want to be able to access the persistent expression variables between runs, and also evaluate constant expressions. Added extra logging to the dynamic loader plug-in for MacOSX. ModuleList objects can now dump their contents with the UUID, arch and full paths being logged with appropriate prefix values. Thread hardened the Communication class a bit by making the connection auto_ptr member into a shared pointer member and then making a local copy of the shared pointer in each method that uses it to make sure another thread can't nuke the connection object while it is being used by another thread. Added a new file to the lldb/test/load_unload test that causes the test a.out file to link to the libd.dylib file all the time. This will allow us to test using the DYLD_LIBRARY_PATH environment variable after moving libd.dylib somewhere else. llvm-svn: 121745

#include "lldb/Core/ValueObjectConstResult.h"
Add support for "dynamic values" for C++ classes. This currently only works for "frame var" and for the expressions that are simple enough to get passed to the "frame var" underpinnings. The parser code will have to be changed to also query for the dynamic types & offsets as it is looking up variables. The behavior of "frame var" is controlled in two ways. You can pass "-d {true/false} to the frame var command to get the dynamic or static value of the variables you are printing. There's also a general setting: target.prefer-dynamic-value (boolean) = 'true' which is consulted if you call "frame var" without supplying a value for the -d option. llvm-svn: 129623

when typing a summary string you can use the %S symbol to explicitly indicate that you want the summary to be used to print the target object (e.g. ${var%S}). this might already be the default if your variable is of an aggregate type new feature: synthetic filters. you can restrict the number of children for your variables to only a meaningful subset - the restricted list of children obeys the typical rules (e.g. summaries prevail over children) - one-line summaries show only the filtered (synthetic) children, if you type an expanded summary string, or you use Python scripts, all the real children are accessible - to provide a synthetic children list use the "type synth add" command, as in: type synth add foo_type --child varA --child varB[0] --child varC->packet->flags[1-4] (you can use ., ->, single-item array operator [N] and bitfield operator [N-M]; array slice access is not supported, giving simplified names to expression paths is not supported) - a new -S option to frame variable and target variable lets you override synthetic children and instead show real ones llvm-svn: 135731

<rdar://problem/12978143> Data formatters now cache themselves. This commit provides a new formatter cache mechanism. Upon resolving a formatter (summary or synthetic), LLDB remembers the resolution for later faster retrieval. Also moved the data formatters subsystem from the core to its own group and folder for easier management, and done some code reorganization. The ObjC runtime v1 now returns a class name if asked for the dynamic type of an object. This is required for formatters caching to work with the v1 runtime. Lastly, this commit disposes of the old hack where ValueObjects had to remember whether they were queried for formatters with their static or dynamic type. Now the ValueObjectDynamicValue class works well enough that we can use its dynamic value setting for the same purpose. llvm-svn: 173728

<rdar://problem/14393032> DumpValueObject() 2.0 This checkin restores pre-Xcode5 functionality to the "po" (expr -O) command: - expr now has a new --description-verbosity (-v) argument, which takes either compact or full as a value (-v is the same as -vfull) When the full mode is on, "po" will show the extended output with type name, persistent variable name and value, as in (lldb) expr -O -v -- foo (id) $0 = 0x000000010010baf0 { 1 = 2; 2 = 3; } When -v is omitted, or -vcompact is passed, the Xcode5-style output will be shown, as in (lldb) expr -O -- foo { 1 = 2; 2 = 3; } - for a non-ObjectiveC object, LLDB will still try to retrieve a summary and/or value to display (lldb) po 5 5 -v also works in this mode (lldb) expr -O -vfull -- 5 (int) $4 = 5 On top of that, this is a major refactoring of the ValueObject printing code. The functionality is now factored into a ValueObjectPrinter class for easier maintenance in the future DumpValueObject() was turned into an instance method ValueObject::Dump() which simply calls through to the printer code, Dump_Impl has been removed Test case to follow llvm-svn: 191694

Add the ability for an SBValue to create a persisted version of itself. Such a persisted version is equivalent to evaluating the value via the expression evaluator, and holding on to the $n result of the expression, except this API can be used on SBValues that do not obviously come from an expression (e.g. are the result of a memory lookup) Expose this via SBValue::Persist() in our public API layer, and ValueObject::Persist() in the lldb_private layer Includes testcase Fixes rdar://19136664 llvm-svn: 223711

Python summary strings: - you can use a Python script to write a summary string for data-types, in one of three ways: -P option and typing the script a line at a time -s option and passing a one-line Python script -F option and passing the name of a Python function these options all work for the "type summary add" command your Python code (if provided through -P or -s) is wrapped in a function that accepts two parameters: valobj (a ValueObject) and dict (an LLDB internal dictionary object). if you use -F and give a function name, you're expected to define the function on your own and with the right prototype. your function, however defined, must return a Python string - test case for the Python summary feature - a few quirks: Python summaries cannot have names, and cannot use regex as type names both issues will be fixed ASAP major redesign of type summary code: - type summary working with strings and type summary working with Python code are two classes, with a common base class SummaryFormat - SummaryFormat classes now are able to actively format objects rather than just aggregating data - cleaner code to print descriptions for summaries the public API now exports a method to easily navigate a ValueObject hierarchy New InputReaderEZ and PriorityPointerPair classes Several minor fixes and improvements llvm-svn: 135238

<rdar://problem/13623698> This patch fixes the issue that we were using the C stack as a measure of depth of ValueObject hierarchies, in the sense that we were assuming that recursive ValueObject operations would never be deeper than the stack allows. This assumption is easy to prove wrong, however. For instance, after ~10k runs through this loop: struct node { int value; node* child; node (int x) { value = x; child = nullptr; } }; int main () { node root(1); node* ptr = &root; int j = 2; while (1) { ptr->child = new node(j++); ptr = ptr->child; } return 0; } the deepmost child object will be deeper than the stack on most architectures, and we would be unable to display it This checkin fixes the issue by introducing a notion of root of ValueObject hierarchies. In a couple cases, we have to use an iterative algorithm instead of going to the root because we want to allow deeper customizations (e.g. formats, dynamic values). While the patch passes our test suite without regressions, it is a good idea to keep eyes open for any unexpected behavior (recursion can be subtle..) Also, I am hesitant to introduce a test case since failing at this will not just be marked as an "F", but most definitely crash LLDB. llvm-svn: 179330

StackFrame objects now own ValueObjects for any frame variables (locals, args, function statics, file globals and static variables) that a frame contains.

StackFrame::GetVariableList now takes a boolean to indicate if we want to get the frame compile unit globals and static variables. The value objects in the stack frames can now correctly track when they have been modified. There are a few more tweaks needed to complete this work. The biggest issue is when stepping creates partial stacks (just frame zero usually) and causes previous stack frames not to match up with the current stack frames because the previous frames only has frame zero. We don't really want to require that all previous frames be complete since stepping often must check stack frames to complete their jobs. I will fix this issue tomorrow. llvm-svn: 112800

We don't really want to require that all previous frames be complete since stepping often must check stack frames to complete their jobs. I will fix this issue tomorrow. llvm-svn: 112800

StackFrame objects now own ValueObjects for any frame variables (locals, args, function statics, file globals and static variables) that a frame contains. The StackFrame objects can give out ValueObjects instances for each variable which allows us to track when a variable changes and doesn't depend on variable names when getting value objects. StackFrame::GetVariableList now takes a boolean to indicate if we want to get the frame compile unit globals and static variables. The value objects in the stack frames can now correctly track when they have been modified. There are a few more tweaks needed to complete this work.

Modified LLDB expressions to not have to JIT and run code just to see variable values or persistent expression variables. Now if an expression consists of a value that is a child of a variable, or of a persistent variable only, we will create a value object for it and make a ValueObjectConstResult from it to freeze the value (for program variables only, not persistent variables) and avoid running JITed code. For everything else we still parse up and JIT code and run it in the inferior. There was also a lot of clean up in the expression code. I made the ClangExpressionVariables be stored in collections of shared pointers instead of in collections of objects. This will help stop a lot of copy constructors on these large objects and also cleans up the code considerably. The persistent clang expression variables were moved over to the Target to ensure they persist across process executions. Added the ability for lldb_private::Target objects to evaluate expressions. We want to evaluate expressions at the target level in case we aren't running yet, or we have just completed running. We still want to be able to access the persistent expression variables between runs, and also evaluate constant expressions. Added extra logging to the dynamic loader plug-in for MacOSX. ModuleList objects can now dump their contents with the UUID, arch and full paths being logged with appropriate prefix values. Thread hardened the Communication class a bit by making the connection auto_ptr member into a shared pointer member and then making a local copy of the shared pointer in each method that uses it to make sure another thread can't nuke the connection object while it is being used by another thread. Added a new file to the lldb/test/load_unload test that causes the test a.out file to link to the libd.dylib file all the time. This will allow us to test using the DYLD_LIBRARY_PATH environment variable after moving libd.dylib somewhere else. llvm-svn: 121745

This commit adds a new top subcommand "summary" to command type named "type". Currently this command implements three commands: type summary add <format> <typename1> [<typename2> ...] type summary delete <typename1> [<typename2> ...] type summary list [<typename1> [<typename2>] ...] type summary clear This allows you to specify the default format that will be used to display summaries for variables, shown when you use "frame variable" or "expression", or the SBValue classes. Examples: type summary add "x = ${var.x}" Point type summary list type summary add --one-liner SimpleType llvm-svn: 134108

several improvements to "type summary": - type names can now be regular expressions (exact matching is done first, and is faster) - integral (and floating) types can be printed as bitfields, i.e. ${var[low-high]} will extract bits low thru high of the value and print them - array subscripts are supported, both for arrays and for pointers. the syntax is ${*var[low-high]}, or ${*var[]} to print the whole array (the latter only works for statically sized arrays) - summary is now printed by default when a summary string references a variable. if that variable's type has no summary, value is printed instead. to force value, you can use %V as a format specifier - basic support for ObjectiveC: - ObjectiveC inheritance chains are now walked through - %@ can be specified as a summary format, to print the ObjectiveC runtime description for an object - some bug fixes llvm-svn: 134293

Added support for looking up the complete type for Objective-C classes. This allows LLDB to find ivars declared in class extensions in modules other than where the debugger is currently stopped (we already supported this when the debugger was stopped in the same module as the definition). This involved the following main changes: - The ObjCLanguageRuntime now knows how to hunt for the authoritative version of an Objective-C type. It looks for the symbol indicating a definition, and then gets the type from the module containing that symbol. - ValueObjects now report their type with a potential override, and the override is set if the type of the ValueObject is an Objective-C class or pointer type that is defined somewhere other than the original reported type. This means that "frame variable" will always use the complete type if one is available. - The ClangASTSource now looks for the complete type when looking for ivars. This means that "expr" will always use the complete type if one is available. - I added a testcase that verifies that both "frame variable" and "expr" work. llvm-svn: 151214

Redesign of the interaction between Python and frozen objects: - introduced two new classes ValueObjectConstResultChild and ValueObjectConstResultImpl: the first one is a ValueObjectChild obtained from a ValueObjectConstResult, the second is a common implementation backend for VOCR and VOCRCh of method calls meant to read through pointers stored in frozen objects ; now such reads transparently move from host to target as required - as a consequence of the above, removed code that made target-memory copies of expression results in several places throughout LLDB, and also removed code that enabled to recognize an expression result VO as such - introduced a new GetPointeeData() method in ValueObject that lets you read a given amount of objects of type T from a VO representing a T* or T[], and doing dereferences transparently in private layer it returns a DataExtractor ; in public layer it returns an instance of a newly created lldb::SBData - as GetPointeeData() does the right thing for both frozen and non-frozen ValueObject's, reimplemented ReadPointedString() to use it en lieu of doing the raw read itself - introduced a new GetData() method in ValueObject that lets you get a copy of the data that backs the ValueObject (for pointers, this returns the address without any previous dereferencing steps ; for arrays it actually reads the whole chunk of memory) in public layer this returns an SBData, just like GetPointeeData() - introduced a new CreateValueFromData() method in SBValue that lets you create a new SBValue from a chunk of data wrapped in an SBData the limitation to remember for this kind of SBValue is that they have no address: extracting the address-of for these objects (with any of GetAddress(), GetLoadAddress() and AddressOf()) will return invalid values - added several tests to check that "p"-ing objects (STL classes, char* and char[]) will do the right thing Solved a bug where global pointers to global variables were not dereferenced correctly for display New target setting "max-string-summary-length" gives the maximum number of characters to show in a string when summarizing it, instead of the hardcoded 128 Solved a bug where the summary for char[] and char* would not be shown if the ValueObject's were dumped via the "p" command Removed m_pointers_point_to_load_addrs from ValueObject. Introduced a new m_address_type_of_children, which each ValueObject can set to tell the address type of any pointers and/or references it creates. In the current codebase, this is load address most of the time (the only notable exception being file addresses that generate file address children UNLESS we have a live process) Updated help text for summary-string Fixed an issue in STL formatters where std::stlcontainer::iterator would match the container's synthetic children providers Edited the syntax and help for some commands to have proper argument types llvm-svn: 139160

<rdar://problem/13623698> This patch fixes the issue that we were using the C stack as a measure of depth of ValueObject hierarchies, in the sense that we were assuming that recursive ValueObject operations would never be deeper than the stack allows. This assumption is easy to prove wrong, however. For instance, after ~10k runs through this loop: struct node { int value; node* child; node (int x) { value = x; child = nullptr; } }; int main () { node root(1); node* ptr = &root; int j = 2; while (1) { ptr->child = new node(j++); ptr = ptr->child; } return 0; } the deepmost child object will be deeper than the stack on most architectures, and we would be unable to display it This checkin fixes the issue by introducing a notion of root of ValueObject hierarchies. In a couple cases, we have to use an iterative algorithm instead of going to the root because we want to allow deeper customizations (e.g. formats, dynamic values). While the patch passes our test suite without regressions, it is a good idea to keep eyes open for any unexpected behavior (recursion can be subtle..) Also, I am hesitant to introduce a test case since failing at this will not just be marked as an "F", but most definitely crash LLDB. llvm-svn: 179330

Currently this command implements three commands: type summary add <format> <typename1> [<typename2> ...] type summary delete <typename1> [<typename2> ...] type summary list [<typename1> [<typename2>] ...] type summary clear This allows you to specify the default format that will be used to display summaries for variables, shown when you use "frame variable" or "expression", or the SBValue classes. Examples: type summary add "x = ${var.x}" Point type summary list type summary add --one-liner SimpleType llvm-svn: 134108

m_is_deref_of_parent (false),
several improvements to "type summary": - type names can now be regular expressions (exact matching is done first, and is faster) - integral (and floating) types can be printed as bitfields, i.e. ${var[low-high]} will extract bits low thru high of the value and print them - array subscripts are supported, both for arrays and for pointers. the syntax is ${*var[low-high]}, or ${*var[]} to print the whole array (the latter only works for statically sized arrays) - summary is now printed by default when a summary string references a variable. if that variable's type has no summary, value is printed instead. to force value, you can use %V as a format specifier - basic support for ObjectiveC: - ObjectiveC inheritance chains are now walked through - %@ can be specified as a summary format, to print the ObjectiveC runtime description for an object - some bug fixes llvm-svn: 134293

m_is_array_item_for_pointer(false),
new syntax for summary strings: - ${*expr} now simply means to dereference expr before actually using it - bitfields, array ranges and pointer ranges now work in a (hopefully) more natural and language-compliant way a new class TypeHierarchyNavigator replicates the behavior of the FormatManager in going through type hierarchies when one-lining summary strings, children's summaries can be used as well as values llvm-svn: 134458

m_is_bitfield_for_scalar(false),
Public API changes: - Completely new implementation of SBType - Various enhancements in several other classes Python synthetic children providers for std::vector<T>, std::list<T> and std::map<K,V>: - these return the actual elements into the container as the children of the container - basic template name parsing that works (hopefully) on both Clang and GCC - find them in examples/synthetic and in the test suite in functionalities/data-formatter/data-formatter-python-synth New summary string token ${svar : - the syntax is just the same as in ${var but this new token lets you read the values coming from the synthetic children provider instead of the actual children - Python providers above provide a synthetic child len that returns the number of elements into the container Full bug fix for the issue in which getting byte size for a non-complete type would crash LLDB Several other fixes, including: - inverted the order of arguments in the ClangASTType constructor - EvaluationPoint now only returns SharedPointer's to Target and Process - the help text for several type subcommands now correctly indicates argument-less options as such llvm-svn: 136504

m_is_child_at_offset(false),
Added support for looking up the complete type for Objective-C classes. This allows LLDB to find ivars declared in class extensions in modules other than where the debugger is currently stopped (we already supported this when the debugger was stopped in the same module as the definition). This involved the following main changes: - The ObjCLanguageRuntime now knows how to hunt for the authoritative version of an Objective-C type. It looks for the symbol indicating a definition, and then gets the type from the module containing that symbol. - ValueObjects now report their type with a potential override, and the override is set if the type of the ValueObject is an Objective-C class or pointer type that is defined somewhere other than the original reported type. This means that "frame variable" will always use the complete type if one is available. - The ClangASTSource now looks for the complete type when looking for ivars. This means that "expr" will always use the complete type if one is available. - I added a testcase that verifies that both "frame variable" and "expr" work. llvm-svn: 151214

Redesign of the interaction between Python and frozen objects: - introduced two new classes ValueObjectConstResultChild and ValueObjectConstResultImpl: the first one is a ValueObjectChild obtained from a ValueObjectConstResult, the second is a common implementation backend for VOCR and VOCRCh of method calls meant to read through pointers stored in frozen objects ; now such reads transparently move from host to target as required - as a consequence of the above, removed code that made target-memory copies of expression results in several places throughout LLDB, and also removed code that enabled to recognize an expression result VO as such - introduced a new GetPointeeData() method in ValueObject that lets you read a given amount of objects of type T from a VO representing a T* or T[], and doing dereferences transparently in private layer it returns a DataExtractor ; in public layer it returns an instance of a newly created lldb::SBData - as GetPointeeData() does the right thing for both frozen and non-frozen ValueObject's, reimplemented ReadPointedString() to use it en lieu of doing the raw read itself - introduced a new GetData() method in ValueObject that lets you get a copy of the data that backs the ValueObject (for pointers, this returns the address without any previous dereferencing steps ; for arrays it actually reads the whole chunk of memory) in public layer this returns an SBData, just like GetPointeeData() - introduced a new CreateValueFromData() method in SBValue that lets you create a new SBValue from a chunk of data wrapped in an SBData the limitation to remember for this kind of SBValue is that they have no address: extracting the address-of for these objects (with any of GetAddress(), GetLoadAddress() and AddressOf()) will return invalid values - added several tests to check that "p"-ing objects (STL classes, char* and char[]) will do the right thing Solved a bug where global pointers to global variables were not dereferenced correctly for display New target setting "max-string-summary-length" gives the maximum number of characters to show in a string when summarizing it, instead of the hardcoded 128 Solved a bug where the summary for char[] and char* would not be shown if the ValueObject's were dumped via the "p" command Removed m_pointers_point_to_load_addrs from ValueObject.

<rdar://problem/12978143> Data formatters now cache themselves. This commit provides a new formatter cache mechanism. Upon resolving a formatter (summary or synthetic), LLDB remembers the resolution for later faster retrieval. Also moved the data formatters subsystem from the core to its own group and folder for easier management, and done some code reorganization. The ObjC runtime v1 now returns a class name if asked for the dynamic type of an object. This is required for formatters caching to work with the v1 runtime. Lastly, this commit disposes of the old hack where ValueObjects had to remember whether they were queried for formatters with their static or dynamic type. Now the ValueObjectDynamicValue class works well enough that we can use its dynamic value setting for the same purpose. llvm-svn: 173728

Added the notion that a value object can be constant by adding: bool ValueObject::GetIsConstant() const; void ValueObject::SetIsConstant(); This will stop anything from being re-evaluated within the value object so that constant result value objects can maintain their frozen values without anything being updated or changed within the value object. Made it so the ValueObjectConstResult can be constructed with an lldb_private::Error object to allow for expression results to have errors. Since ValueObject objects contain error objects, I changed the expression evaluation in ClangUserExpression from static Error ClangUserExpression::Evaluate (ExecutionContext &exe_ctx, const char *expr_cstr, lldb::ValueObjectSP &result_valobj_sp); to: static lldb::ValueObjectSP Evaluate (ExecutionContext &exe_ctx, const char *expr_cstr); Even though expression parsing is borked right now (pending fixes coming from Sean Callanan), I filled in the implementation for: SBValue SBFrame::EvaluateExpression (const char *expr); Modified all expression code to deal with the above changes. llvm-svn: 115589

Massive enumeration name changes: a number of enums in ValueObject were not following the naming pattern Changes to synthetic children: - the update(self): function can now (optionally) return a value - if it returns boolean value True, ValueObjectSyntheticFilter will not clear its caches across stop-points this should allow better performance for Python-based synthetic children when one can be sure that the child ValueObjects have not changed - making a difference between a synthetic VO and a VO with a synthetic value: now a ValueObjectSyntheticFilter will not return itself as its own synthetic value, but will (correctly) claim to itself be synthetic - cleared up the internal synthetic children architecture to make a more consistent use of pointers and references instead of shared pointers when possible - major cleanup of unnecessary #include, data and functions in ValueObjectSyntheticFilter itself - removed the SyntheticValueType enum and replaced it with a plain boolean (to which it was equivalent in the first place) Some clean ups to the summary generation code Centralized the code that clears out user-visible strings and data in ValueObject More efficient summaries for libc++ containers llvm-svn: 153061

Python summary strings: - you can use a Python script to write a summary string for data-types, in one of three ways: -P option and typing the script a line at a time -s option and passing a one-line Python script -F option and passing the name of a Python function these options all work for the "type summary add" command your Python code (if provided through -P or -s) is wrapped in a function that accepts two parameters: valobj (a ValueObject) and dict (an LLDB internal dictionary object). if you use -F and give a function name, you're expected to define the function on your own and with the right prototype. your function, however defined, must return a Python string - test case for the Python summary feature - a few quirks: Python summaries cannot have names, and cannot use regex as type names both issues will be fixed ASAP major redesign of type summary code: - type summary working with strings and type summary working with Python code are two classes, with a common base class SummaryFormat - SummaryFormat classes now are able to actively format objects rather than just aggregating data - cleaner code to print descriptions for summaries the public API now exports a method to easily navigate a ValueObject hierarchy New InputReaderEZ and PriorityPointerPair classes Several minor fixes and improvements llvm-svn: 135238

Redesign of the interaction between Python and frozen objects: - introduced two new classes ValueObjectConstResultChild and ValueObjectConstResultImpl: the first one is a ValueObjectChild obtained from a ValueObjectConstResult, the second is a common implementation backend for VOCR and VOCRCh of method calls meant to read through pointers stored in frozen objects ; now such reads transparently move from host to target as required - as a consequence of the above, removed code that made target-memory copies of expression results in several places throughout LLDB, and also removed code that enabled to recognize an expression result VO as such - introduced a new GetPointeeData() method in ValueObject that lets you read a given amount of objects of type T from a VO representing a T* or T[], and doing dereferences transparently in private layer it returns a DataExtractor ; in public layer it returns an instance of a newly created lldb::SBData - as GetPointeeData() does the right thing for both frozen and non-frozen ValueObject's, reimplemented ReadPointedString() to use it en lieu of doing the raw read itself - introduced a new GetData() method in ValueObject that lets you get a copy of the data that backs the ValueObject (for pointers, this returns the address without any previous dereferencing steps ; for arrays it actually reads the whole chunk of memory) in public layer this returns an SBData, just like GetPointeeData() - introduced a new CreateValueFromData() method in SBValue that lets you create a new SBValue from a chunk of data wrapped in an SBData the limitation to remember for this kind of SBValue is that they have no address: extracting the address-of for these objects (with any of GetAddress(), GetLoadAddress() and AddressOf()) will return invalid values - added several tests to check that "p"-ing objects (STL classes, char* and char[]) will do the right thing Solved a bug where global pointers to global variables were not dereferenced correctly for display New target setting "max-string-summary-length" gives the maximum number of characters to show in a string when summarizing it, instead of the hardcoded 128 Solved a bug where the summary for char[] and char* would not be shown if the ValueObject's were dumped via the "p" command Removed m_pointers_point_to_load_addrs from ValueObject. Introduced a new m_address_type_of_children, which each ValueObject can set to tell the address type of any pointers and/or references it creates. In the current codebase, this is load address most of the time (the only notable exception being file addresses that generate file address children UNLESS we have a live process) Updated help text for summary-string Fixed an issue in STL formatters where std::stlcontainer::iterator would match the container's synthetic children providers Edited the syntax and help for some commands to have proper argument types llvm-svn: 139160

<rdar://problem/12978143> Data formatters now cache themselves. This commit provides a new formatter cache mechanism. Upon resolving a formatter (summary or synthetic), LLDB remembers the resolution for later faster retrieval. Also moved the data formatters subsystem from the core to its own group and folder for easier management, and done some code reorganization. The ObjC runtime v1 now returns a class name if asked for the dynamic type of an object. This is required for formatters caching to work with the v1 runtime. Lastly, this commit disposes of the old hack where ValueObjects had to remember whether they were queried for formatters with their static or dynamic type.

Added support for looking up the complete type for Objective-C classes. This allows LLDB to find ivars declared in class extensions in modules other than where the debugger is currently stopped (we already supported this when the debugger was stopped in the same module as the definition). This involved the following main changes: - The ObjCLanguageRuntime now knows how to hunt for the authoritative version of an Objective-C type. It looks for the symbol indicating a definition, and then gets the type from the module containing that symbol. - ValueObjects now report their type with a potential override, and the override is set if the type of the ValueObject is an Objective-C class or pointer type that is defined somewhere other than the original reported type. This means that "frame variable" will always use the complete type if one is available. - The ClangASTSource now looks for the complete type when looking for ivars. This means that "expr" will always use the complete type if one is available. - I added a testcase that verifies that both "frame variable" and "expr" work. llvm-svn: 151214

Huge change to clean up types. A long time ago we start with clang types that were created by the symbol files and there were many functions in lldb_private::ClangASTContext that helped.

There were a lot of places where we would pass around a raw clang_type_t and also pass along a clang::ASTContext separately. This left room for error. This checkin change all type code over to use ClangASTType everywhere and I cleaned up the interfaces quite a bit.

Be more careful when overriding the type for a ValueObject, and make sure that ValueObjects that have null type names (because they have null types) also have null qualified type names. This avoids some potential crashes if ValueObject::GetQualifiedTypeName tries to get the name of their type by calling GetClangTypeImpl(). llvm-svn: 153718

ValueObject::GetClangType ()
{
Huge change to clean up types. A long time ago we start with clang types that were created by the symbol files and there were many functions in lldb_private::ClangASTContext that helped. Later we create ClangASTType which contains a clang::ASTContext and an opauque QualType, but we didn't switch over to fully using it. There were a lot of places where we would pass around a raw clang_type_t and also pass along a clang::ASTContext separately. This left room for error. This checkin change all type code over to use ClangASTType everywhere and I cleaned up the interfaces quite a bit. Any code that was in ClangASTContext that was type related, was moved over into ClangASTType. All code that used these types was switched over to use all of the new goodness. llvm-svn: 186130

return MaybeCalculateCompleteType();
Added support for looking up the complete type for Objective-C classes. This allows LLDB to find ivars declared in class extensions in modules other than where the debugger is currently stopped (we already supported this when the debugger was stopped in the same module as the definition). This involved the following main changes: - The ObjCLanguageRuntime now knows how to hunt for the authoritative version of an Objective-C type. It looks for the symbol indicating a definition, and then gets the type from the module containing that symbol. - ValueObjects now report their type with a potential override, and the override is set if the type of the ValueObject is an Objective-C class or pointer type that is defined somewhere other than the original reported type. This means that "frame variable" will always use the complete type if one is available. - The ClangASTSource now looks for the complete type when looking for ivars. This means that "expr" will always use the complete type if one is available. - I added a testcase that verifies that both "frame variable" and "expr" work. llvm-svn: 151214

<rdar://problem/15144376> This commit reimplements the TypeImpl class (the class that backs SBType) in terms of a static,dynamic type pair This is useful for those cases when the dynamic type of an ObjC variable can only be obtained in terms of an "hollow" type with no ivars In that case, we could either go with the static type (+iVar information) or with the dynamic type (+inheritance chain) With the new TypeImpl implementation, we try to combine these two sources of information in order to extract as much information as possible This should improve the functionality of tools that are using the SBType API to do extensive dynamic type inspection llvm-svn: 193564

Path from Ashok Thirumurthi: The attached patch adds eValueTypeVector to lldb_private::Value. The nested struct Vector is patterned after RegisterValue::m_data.buffer. This change to Value allows ClangExpressionDeclMap::LookupDecl to return vector register data for consumption by InterpreterStackFrame::ResolveValue. Note that ResolveValue was tweaked slightly to allocate enough memory for vector registers. An immediate result of this patch is that "expr $xmm0" generates the same results on Linux as on the Mac, which is good enough for TestRegisters.py. In addition, the log of m_memory.PrintData(data_region.m_base, data_region.m_extent) shows that the register content has been resolved successfully. On the other hand, the output is glaringly empty: runCmd: expr $xmm0 output: (unsigned char __attribute__((ext_vector_type(16)))) $0 = {} Expecting sub string: vector_type Matched llvm-svn: 167033

This checking is part one of trying to add some threading safety to our internals. The first part of this is to use a new class: lldb_private::ExecutionContextRef This class holds onto weak pointers to the target, process, thread and frame and it also contains the thread ID and frame Stack ID in case the thread and frame objects go away and come back as new objects that represent the same logical thread/frame. ExecutionContextRef objcets have accessors to access shared pointers for the target, process, thread and frame which might return NULL if the backing object is no longer available. This allows for references to persistent program state without needing to hold a shared pointer to each object and potentially keeping that object around for longer than it needs to be. You can also "Lock" and ExecutionContextRef (which contains weak pointers) object into an ExecutionContext (which contains strong, or shared pointers) with code like ExecutionContext exe_ctx (my_obj->GetExectionContextRef().Lock()); llvm-svn: 150801

Make ValueObject::SetValueFromCString work correctly. Also change the SourceInitFile to look for .lldb-<APPNAME> and source that preferentially if it exists. Also made the breakpoint site report its address as well as its breakpoint number when it gets hit and can't find any the associated locations (usually because the breakpoint got disabled or deleted programmatically between the time it was hit and reported.) Changed ThreadPlanCallFunction to initialize the ivar m_func in the initializers of the constructor, rather than waiting to initialize till later on in the function. Fixed a bug where if you make an SBError and the ask it Success, it returns false. Fixed ValueObject::ResolveValue so that it resolves a temporary value, rather than overwriting the one in the value object. llvm-svn: 137536

<rdar://problem/13069948> Major fixed to allow reading files that are over 4GB. The main problems were that the DataExtractor was using 32 bit offsets as a data cursor, and since we mmap all of our object files we could run into cases where if we had a very large core file that was over 4GB, we were running into the 4GB boundary. So I defined a new "lldb::offset_t" which should be used for all file offsets. After making this change, I enabled warnings for data loss and for enexpected implicit conversions temporarily and found a ton of things that I fixed. Any functions that take an index internally, should use "size_t" for any indexes and also should return "size_t" for any sizes of collections. llvm-svn: 173463

Add support for "dynamic values" for C++ classes. This currently only works for "frame var" and for the expressions that are simple enough to get passed to the "frame var" underpinnings. The parser code will have to be changed to also query for the dynamic types & offsets as it is looking up variables. The behavior of "frame var" is controlled in two ways. You can pass "-d {true/false} to the frame var command to get the dynamic or static value of the variables you are printing. There's also a general setting: target.prefer-dynamic-value (boolean) = 'true' which is consulted if you call "frame var" without supplying a value for the -d option. llvm-svn: 129623

Huge change to clean up types. A long time ago we start with clang types that were created by the symbol files and there were many functions in lldb_private::ClangASTContext that helped. Later we create ClangASTType which contains a clang::ASTContext and an opauque QualType, but we didn't switch over to fully using it. There were a lot of places where we would pass around a raw clang_type_t and also pass along a clang::ASTContext separately. This left room for error. This checkin change all type code over to use ClangASTType everywhere and I cleaned up the interfaces quite a bit. Any code that was in ClangASTContext that was type related, was moved over into ClangASTType. All code that used these types was switched over to use all of the new goodness. llvm-svn: 186130

Added support for finding and global variables in the SBTarget and SBModule level in the public API. Also modified the ValueObject values to be able to display global variables without having a valid running process. The globals will read themselves from the object file section data if there is no process, and from the process if there is one. Also fixed an issue where modifications for dynamic types could cause child values of ValueObjects to not show up if the value was unable to evaluate itself (children of NULL pointer objects). llvm-svn: 134102

Add support for "dynamic values" for C++ classes. This currently only works for "frame var" and for the expressions that are simple enough to get passed to the "frame var" underpinnings. The parser code will have to be changed to also query for the dynamic types & offsets as it is looking up variables. The behavior of "frame var" is controlled in two ways. You can pass "-d {true/false} to the frame var command to get the dynamic or static value of the variables you are printing. There's also a general setting: target.prefer-dynamic-value (boolean) = 'true' which is consulted if you call "frame var" without supplying a value for the -d option. llvm-svn: 129623

<rdar://problem/13069948> Major fixed to allow reading files that are over 4GB. The main problems were that the DataExtractor was using 32 bit offsets as a data cursor, and since we mmap all of our object files we could run into cases where if we had a very large core file that was over 4GB, we were running into the 4GB boundary. So I defined a new "lldb::offset_t" which should be used for all file offsets. After making this change, I enabled warnings for data loss and for enexpected implicit conversions temporarily and found a ton of things that I fixed. Any functions that take an index internally, should use "size_t" for any indexes and also should return "size_t" for any sizes of collections. llvm-svn: 173463

Synthetic values are now automatically enabled and active by default. SBValue is set up to always wrap a synthetic value when one is available. A new setting enable-synthetic-value is provided on the target to disable this behavior. There also is a new GetNonSyntheticValue() API call on SBValue to go back from synthetic to non-synthetic. There is no call to go from non-synthetic to synthetic. The test suite has been changed accordingly. Fallout from changes to type searching: an hack has to be played to make it possible to use maps that contain std::string due to the special name replacement operated by clang Fixing a test case that was using libstdcpp instead of libc++ - caught as a consequence of said changes to type searching llvm-svn: 153495

StackFrame objects now own ValueObjects for any frame variables (locals, args, function statics, file globals and static variables) that a frame contains. The StackFrame objects can give out ValueObjects instances for each variable which allows us to track when a variable changes and doesn't depend on variable names when getting value objects. StackFrame::GetVariableList now takes a boolean to indicate if we want to get the frame compile unit globals and static variables. The value objects in the stack frames can now correctly track when they have been modified. There are a few more tweaks needed to complete this work. The biggest issue is when stepping creates partial stacks (just frame zero usually) and causes previous stack frames not to match up with the current stack frames because the previous frames only has frame zero. We don't really want to require that all previous frames be complete since stepping often must check stack frames to complete their jobs. I will fix this issue tomorrow. llvm-svn: 112800

This checking is part one of trying to add some threading safety to our internals. The first part of this is to use a new class: lldb_private::ExecutionContextRef This class holds onto weak pointers to the target, process, thread and frame and it also contains the thread ID and frame Stack ID in case the thread and frame objects go away and come back as new objects that represent the same logical thread/frame. ExecutionContextRef objcets have accessors to access shared pointers for the target, process, thread and frame which might return NULL if the backing object is no longer available. This allows for references to persistent program state without needing to hold a shared pointer to each object and potentially keeping that object around for longer than it needs to be. You can also "Lock" and ExecutionContextRef (which contains weak pointers) object into an ExecutionContext (which contains strong, or shared pointers) with code like ExecutionContext exe_ctx (my_obj->GetExectionContextRef().Lock()); llvm-svn: 150801

Redesign of the interaction between Python and frozen objects: - introduced two new classes ValueObjectConstResultChild and ValueObjectConstResultImpl: the first one is a ValueObjectChild obtained from a ValueObjectConstResult, the second is a common implementation backend for VOCR and VOCRCh of method calls meant to read through pointers stored in frozen objects ; now such reads transparently move from host to target as required - as a consequence of the above, removed code that made target-memory copies of expression results in several places throughout LLDB, and also removed code that enabled to recognize an expression result VO as such - introduced a new GetPointeeData() method in ValueObject that lets you read a given amount of objects of type T from a VO representing a T* or T[], and doing dereferences transparently in private layer it returns a DataExtractor ; in public layer it returns an instance of a newly created lldb::SBData - as GetPointeeData() does the right thing for both frozen and non-frozen ValueObject's, reimplemented ReadPointedString() to use it en lieu of doing the raw read itself - introduced a new GetData() method in ValueObject that lets you get a copy of the data that backs the ValueObject (for pointers, this returns the address without any previous dereferencing steps ; for arrays it actually reads the whole chunk of memory) in public layer this returns an SBData, just like GetPointeeData() - introduced a new CreateValueFromData() method in SBValue that lets you create a new SBValue from a chunk of data wrapped in an SBData the limitation to remember for this kind of SBValue is that they have no address: extracting the address-of for these objects (with any of GetAddress(), GetLoadAddress() and AddressOf()) will return invalid values - added several tests to check that "p"-ing objects (STL classes, char* and char[]) will do the right thing Solved a bug where global pointers to global variables were not dereferenced correctly for display New target setting "max-string-summary-length" gives the maximum number of characters to show in a string when summarizing it, instead of the hardcoded 128 Solved a bug where the summary for char[] and char* would not be shown if the ValueObject's were dumped via the "p" command Removed m_pointers_point_to_load_addrs from ValueObject.

Add support for "dynamic values" for C++ classes. This currently only works for "frame var" and for the expressions that are simple enough to get passed to the "frame var" underpinnings. The parser code will have to be changed to also query for the dynamic types & offsets as it is looking up variables. The behavior of "frame var" is controlled in two ways. You can pass "-d {true/false} to the frame var command to get the dynamic or static value of the variables you are printing. There's also a general setting: target.prefer-dynamic-value (boolean) = 'true' which is consulted if you call "frame var" without supplying a value for the -d option. llvm-svn: 129623

Move several GetByteSize() calls over to the brave new world of taking an ExecutionContext* And since enough of these are doing the right thing, add a test case to verify we are doing the right thing with freeze drying ObjC object types Fixes rdar://18092770 llvm-svn: 227282

ExecutionContext exe_ctx (GetExecutionContextRef());
Make a more complete fix for always supplying an execution context when getting byte sizes from types. There was a test in the test suite that was triggering the backtrace logging output that requested that the client pass an execution context. Sometimes we need the process for Objective C types because our static notion of the type might not align with the reality when being run in a live runtime. Switched from an "ExecutionContext *" to an "ExecutionContextScope *" for greater ease of use. llvm-svn: 228892

Redesign of the interaction between Python and frozen objects: - introduced two new classes ValueObjectConstResultChild and ValueObjectConstResultImpl: the first one is a ValueObjectChild obtained from a ValueObjectConstResult, the second is a common implementation backend for VOCR and VOCRCh of method calls meant to read through pointers stored in frozen objects ; now such reads transparently move from host to target as required - as a consequence of the above, removed code that made target-memory copies of expression results in several places throughout LLDB, and also removed code that enabled to recognize an expression result VO as such - introduced a new GetPointeeData() method in ValueObject that lets you read a given amount of objects of type T from a VO representing a T* or T[], and doing dereferences transparently in private layer it returns a DataExtractor ; in public layer it returns an instance of a newly created lldb::SBData - as GetPointeeData() does the right thing for both frozen and non-frozen ValueObject's, reimplemented ReadPointedString() to use it en lieu of doing the raw read itself - introduced a new GetData() method in ValueObject that lets you get a copy of the data that backs the ValueObject (for pointers, this returns the address without any previous dereferencing steps ; for arrays it actually reads the whole chunk of memory) in public layer this returns an SBData, just like GetPointeeData() - introduced a new CreateValueFromData() method in SBValue that lets you create a new SBValue from a chunk of data wrapped in an SBData the limitation to remember for this kind of SBValue is that they have no address: extracting the address-of for these objects (with any of GetAddress(), GetLoadAddress() and AddressOf()) will return invalid values - added several tests to check that "p"-ing objects (STL classes, char* and char[]) will do the right thing Solved a bug where global pointers to global variables were not dereferenced correctly for display New target setting "max-string-summary-length" gives the maximum number of characters to show in a string when summarizing it, instead of the hardcoded 128 Solved a bug where the summary for char[] and char* would not be shown if the ValueObject's were dumped via the "p" command Removed m_pointers_point_to_load_addrs from ValueObject.

<rdar://problem/10103468> I started work on being able to add symbol files after a debug session had started with a new "target symfile add" command and quickly ran into problems with stale Address objects in breakpoint locations that had lldb_private::Section pointers into modules that had been removed or replaced. This also let to grabbing stale modules from those sections. So I needed to thread harded the Address, Section and related objects. To do this I modified the ModuleChild class to now require a ModuleSP on initialization so that a weak reference can created. I also changed all places that were handing out "Section *" to have them hand out SectionSP. All ObjectFile, SymbolFile and SymbolVendors were inheriting from ModuleChild so all of the find plug-in, static creation function and constructors now require ModuleSP references instead of Module *. Address objects now have weak references to their sections which can safely go stale when a module gets destructed. This checkin doesn't complete the "target symfile add" command, but it does get us a lot clioser to being able to do such things without a high risk of crashing or memory corruption. llvm-svn: 151336

This checking is part one of trying to add some threading safety to our internals. The first part of this is to use a new class: lldb_private::ExecutionContextRef This class holds onto weak pointers to the target, process, thread and frame and it also contains the thread ID and frame Stack ID in case the thread and frame objects go away and come back as new objects that represent the same logical thread/frame. ExecutionContextRef objcets have accessors to access shared pointers for the target, process, thread and frame which might return NULL if the backing object is no longer available. This allows for references to persistent program state without needing to hold a shared pointer to each object and potentially keeping that object around for longer than it needs to be. You can also "Lock" and ExecutionContextRef (which contains weak pointers) object into an ExecutionContext (which contains strong, or shared pointers) with code like ExecutionContext exe_ctx (my_obj->GetExectionContextRef().Lock()); llvm-svn: 150801

This checking is part one of trying to add some threading safety to our internals.

ExecutionContextRef objcets have accessors to access shared pointers for the target, process, thread and frame which might return NULL if the backing object is no longer available. This allows for references to persistent program state without needing to hold a shared pointer to each object and potentially keeping that object around for longer than it needs to be. You can also "Lock" and ExecutionContextRef (which contains weak pointers) object into an ExecutionContext (which contains strong, or shared pointers) with code like ExecutionContext exe_ctx (my_obj->GetExectionContextRef().Lock()); llvm-svn: 150801

[ValueObject::GetPointeeData] Get addr from value for eValueHostAddress values. Summary: After r236447, ValueObject::GetAddressOf returns LLDB_INVALID_ADDRESS when the value type is eValueHostAddress. For such a case, clients of GetAddressOf should get the address from the scalar part of the value instead of using the value returned by GetAddressOf directly. This change also makes ValueObject::GetAddressOf set the address type to eAddressTypeHost for values of eValueHostAddress so that clients can recognize that they need to fetch the address from the scalar part of the value.

Huge change to clean up types. A long time ago we start with clang types that were created by the symbol files and there were many functions in lldb_private::ClangASTContext that helped. Later we create ClangASTType which contains a clang::ASTContext and an opauque QualType, but we didn't switch over to fully using it. There were a lot of places where we would pass around a raw clang_type_t and also pass along a clang::ASTContext separately. This left room for error. This checkin change all type code over to use ClangASTType everywhere and I cleaned up the interfaces quite a bit. Any code that was in ClangASTContext that was type related, was moved over into ClangASTType. All code that used these types was switched over to use all of the new goodness. llvm-svn: 186130

I have added a testcase that exercises various special cases of SBValue::SetData(). llvm-svn: 179437

Redesign of the interaction between Python and frozen objects: - introduced two new classes ValueObjectConstResultChild and ValueObjectConstResultImpl: the first one is a ValueObjectChild obtained from a ValueObjectConstResult, the second is a common implementation backend for VOCR and VOCRCh of method calls meant to read through pointers stored in frozen objects ; now such reads transparently move from host to target as required - as a consequence of the above, removed code that made target-memory copies of expression results in several places throughout LLDB, and also removed code that enabled to recognize an expression result VO as such - introduced a new GetPointeeData() method in ValueObject that lets you read a given amount of objects of type T from a VO representing a T* or T[], and doing dereferences transparently in private layer it returns a DataExtractor ; in public layer it returns an instance of a newly created lldb::SBData - as GetPointeeData() does the right thing for both frozen and non-frozen ValueObject's, reimplemented ReadPointedString() to use it en lieu of doing the raw read itself - introduced a new GetData() method in ValueObject that lets you get a copy of the data that backs the ValueObject (for pointers, this returns the address without any previous dereferencing steps ; for arrays it actually reads the whole chunk of memory) in public layer this returns an SBData, just like GetPointeeData() - introduced a new CreateValueFromData() method in SBValue that lets you create a new SBValue from a chunk of data wrapped in an SBData the limitation to remember for this kind of SBValue is that they have no address: extracting the address-of for these objects (with any of GetAddress(), GetLoadAddress() and AddressOf()) will return invalid values - added several tests to check that "p"-ing objects (STL classes, char* and char[]) will do the right thing Solved a bug where global pointers to global variables were not dereferenced correctly for display New target setting "max-string-summary-length" gives the maximum number of characters to show in a string when summarizing it, instead of the hardcoded 128 Solved a bug where the summary for char[] and char* would not be shown if the ValueObject's were dumped via the "p" command Removed m_pointers_point_to_load_addrs from ValueObject.

Huge change to clean up types. A long time ago we start with clang types that were created by the symbol files and there were many functions in lldb_private::ClangASTContext that helped. Later we create ClangASTType which contains a clang::ASTContext and an opauque QualType, but we didn't switch over to fully using it. There were a lot of places where we would pass around a raw clang_type_t and also pass along a clang::ASTContext separately. This left room for error. This checkin change all type code over to use ClangASTType everywhere and I cleaned up the interfaces quite a bit.

Extend synthetic children to produce synthetic values (as in, those that GetValueAsUnsigned(), GetValueAsCString() would return) The way to do this is to write a synthetic child provider for your type, and have it vend the (optional) get_value function. If get_value is defined, and it returns a valid SBValue, that SBValue's value (as in lldb_private::Value) will be used as the synthetic ValueObject's Value The rationale for doing things this way is twofold: - there are many possible ways to define a "value" (SBData, a Python number, ...) but SBValue seems general enough as a thing that stores a "value", so we just trade values that way and that keeps our currency trivial - we could introduce a new level of layering (ValueObjectSyntheticValue), a new kind of formatter (synthetic value producer), but that would complicate the model (can I have a dynamic with no synthetic children but synthetic value? synthetic value with synthetic children but no dynamic?), and I really couldn't see much benefit to be reaped from this added complexity in the matrix On the other hand, just defining a synthetic child provider with a get_value but returning no actual children is easy enough that it's not a significant road-block to adoption of this feature Comes with a test case llvm-svn: 219330

Added a new plug-in type: lldb_private::OperatingSystem. The operating system plug-ins are add on plug-ins for the lldb_private::Process class that can add thread contexts that are read from memory. It is common in kernels to have a lot of threads that are not currently executing on any cores (JTAG debugging also follows this sort of thing) and are context switched out whose state is stored in memory data structures. Clients can now subclass the OperatingSystem plug-ins and then make sure their Create functions correcltly only enable themselves when the right binary/target triple are being debugged. The operating system plug-ins get a chance to attach themselves to processes just after launching or attaching and are given a lldb_private::Process object pointer which can be inspected to see if the main executable, target triple, or any shared libraries match a case where the OS plug-in should be used. Currently the OS plug-ins can create new threads, define the register contexts for these threads (which can all be different if desired), and populate and manage the thread info (stop reason, registers in the register context) as the debug session goes on. llvm-svn: 138228

Added a new plug-in type: lldb_private::OperatingSystem. The operating system plug-ins are add on plug-ins for the lldb_private::Process class that can add thread contexts that are read from memory. It is common in kernels to have a lot of threads that are not currently executing on any cores (JTAG debugging also follows this sort of thing) and are context switched out whose state is stored in memory data structures. Clients can now subclass the OperatingSystem plug-ins and then make sure their Create functions correcltly only enable themselves when the right binary/target triple are being debugged. The operating system plug-ins get a chance to attach themselves to processes just after launching or attaching and are given a lldb_private::Process object pointer which can be inspected to see if the main executable, target triple, or any shared libraries match a case where the OS plug-in should be used. Currently the OS plug-ins can create new threads, define the register contexts for these threads (which can all be different if desired), and populate and manage the thread info (stop reason, registers in the register context) as the debug session goes on. llvm-svn: 138228

// If our byte size is zero this is an aggregate type that has children
Extend synthetic children to produce synthetic values (as in, those that GetValueAsUnsigned(), GetValueAsCString() would return) The way to do this is to write a synthetic child provider for your type, and have it vend the (optional) get_value function. If get_value is defined, and it returns a valid SBValue, that SBValue's value (as in lldb_private::Value) will be used as the synthetic ValueObject's Value The rationale for doing things this way is twofold: - there are many possible ways to define a "value" (SBData, a Python number, ...) but SBValue seems general enough as a thing that stores a "value", so we just trade values that way and that keeps our currency trivial - we could introduce a new level of layering (ValueObjectSyntheticValue), a new kind of formatter (synthetic value producer), but that would complicate the model (can I have a dynamic with no synthetic children but synthetic value? synthetic value with synthetic children but no dynamic?), and I really couldn't see much benefit to be reaped from this added complexity in the matrix On the other hand, just defining a synthetic child provider with a get_value but returning no actual children is easy enough that it's not a significant road-block to adoption of this feature Comes with a test case llvm-svn: 219330

<rdar://problem/13069948> Major fixed to allow reading files that are over 4GB. The main problems were that the DataExtractor was using 32 bit offsets as a data cursor, and since we mmap all of our object files we could run into cases where if we had a very large core file that was over 4GB, we were running into the 4GB boundary. So I defined a new "lldb::offset_t" which should be used for all file offsets. After making this change, I enabled warnings for data loss and for enexpected implicit conversions temporarily and found a ton of things that I fixed.

Extend synthetic children to produce synthetic values (as in, those that GetValueAsUnsigned(), GetValueAsCString() would return) The way to do this is to write a synthetic child provider for your type, and have it vend the (optional) get_value function. If get_value is defined, and it returns a valid SBValue, that SBValue's value (as in lldb_private::Value) will be used as the synthetic ValueObject's Value The rationale for doing things this way is twofold: - there are many possible ways to define a "value" (SBData, a Python number, ...) but SBValue seems general enough as a thing that stores a "value", so we just trade values that way and that keeps our currency trivial - we could introduce a new level of layering (ValueObjectSyntheticValue), a new kind of formatter (synthetic value producer), but that would complicate the model (can I have a dynamic with no synthetic children but synthetic value? synthetic value with synthetic children but no dynamic?), and I really couldn't see much benefit to be reaped from this added complexity in the matrix On the other hand, just defining a synthetic child provider with a get_value but returning no actual children is easy enough that it's not a significant road-block to adoption of this feature Comes with a test case llvm-svn: 219330

<rdar://problem/16006373> Revert the spirit of r199857 - a convincing case can be made that overriding a summary's format markers behind its back is not the right thing to do This commit reverts the behavior of the code to the previous model, and changes the test case to validate the opposite of what it was validating before llvm-svn: 201455

named summaries: - a new --name option for "type summary add" lets you give a name to a summary - a new --summary option for "frame variable" lets you bind a named summary to one or more variables ${var%s} now works for printing the value of 0-terminated CStrings type format test case now tests for cascading - this is disabled on GCC because GCC may end up stripping typedef chains, basically breaking cascading new design for the FormatNavigator class new template class CleanUp2 meant to support cleanup routines with 1 additional parameter beyond resource handle llvm-svn: 134943

Second round of code cleanups: - reorganizing classes layout to have public part first Typedefs that we want to keep private, but must be defined for some public code to work correctly are an exception - avoiding methods in the form T foo() { code; } all on one-line - moving method implementations from .h to .cpp whenever feasible Templatized code is an exception and so are very small methods - generally, adhering to coding conventions followed project-wide Functional changes: - fixed an issue where using ${var} in a summary for an aggregate, and then displaying a pointer-to-aggregate would lead to no summary being displayed The issue was not a major one because all ${var} was meant to do in that context was display an error for invalid use of pointer Accordingly fixed test cases and added a new test case llvm-svn: 137944

smarter summary strings: - formats %s %char[] %c and %a now work to print 0-terminated c-strings if they are applied to a char* or char[] even without the [] operator (e.g. ${var%s}) - array formats (char[], intN[], ..) now work when applied to an array of a scalar type even without the [] operator (e.g. ${var%int32_t[]}) LLDB will not crash because of endless loop when trying to obtain a summary for an object that has no value and references itself in its summary string In many cases, a wrong summary string will now display an "<error>" message instead of giving out an empty string llvm-svn: 135007

several improvements to "type summary": - type names can now be regular expressions (exact matching is done first, and is faster) - integral (and floating) types can be printed as bitfields, i.e. ${var[low-high]} will extract bits low thru high of the value and print them - array subscripts are supported, both for arrays and for pointers. the syntax is ${*var[low-high]}, or ${*var[]} to print the whole array (the latter only works for statically sized arrays) - summary is now printed by default when a summary string references a variable. if that variable's type has no summary, value is printed instead. to force value, you can use %V as a format specifier - basic support for ObjectiveC: - ObjectiveC inheritance chains are now walked through - %@ can be specified as a summary format, to print the ObjectiveC runtime description for an object - some bug fixes llvm-svn: 134293

Updated the lldb_private::Flags class to have better method names and made all of the calls inlined in the header file for better performance. Fixed the summary for C string types (array of chars (with any combo if modifiers), and pointers to chars) work in all cases. Fixed an issue where a forward declaration to a clang type could cause itself to resolve itself more than once if, during the resolving of the type itself it caused something to try and resolve itself again. We now remove the clang type from the forward declaration map in the DWARF parser when we start to resolve it and avoid this additional call.

Add support for "dynamic values" for C++ classes. This currently only works for "frame var" and for the expressions that are simple enough to get passed to the "frame var" underpinnings. The parser code will have to be changed to also query for the dynamic types & offsets as it is looking up variables. The behavior of "frame var" is controlled in two ways. You can pass "-d {true/false} to the frame var command to get the dynamic or static value of the variables you are printing. There's also a general setting: target.prefer-dynamic-value (boolean) = 'true' which is consulted if you call "frame var" without supplying a value for the -d option. llvm-svn: 129623

Path from Ashok Thirumurthi: The attached patch adds eValueTypeVector to lldb_private::Value. The nested struct Vector is patterned after RegisterValue::m_data.buffer. This change to Value allows ClangExpressionDeclMap::LookupDecl to return vector register data for consumption by InterpreterStackFrame::ResolveValue. Note that ResolveValue was tweaked slightly to allocate enough memory for vector registers. An immediate result of this patch is that "expr $xmm0" generates the same results on Linux as on the Mac, which is good enough for TestRegisters.py. In addition, the log of m_memory.PrintData(data_region.m_base, data_region.m_extent) shows that the register content has been resolved successfully. On the other hand, the output is glaringly empty: runCmd: expr $xmm0 output: (unsigned char __attribute__((ext_vector_type(16)))) $0 = {} Expecting sub string: vector_type Matched llvm-svn: 167033

Add support for "dynamic values" for C++ classes. This currently only works for "frame var" and for the expressions that are simple enough to get passed to the "frame var" underpinnings. The parser code will have to be changed to also query for the dynamic types & offsets as it is looking up variables. The behavior of "frame var" is controlled in two ways. You can pass "-d {true/false} to the frame var command to get the dynamic or static value of the variables you are printing. There's also a general setting: target.prefer-dynamic-value (boolean) = 'true' which is consulted if you call "frame var" without supplying a value for the -d option. llvm-svn: 129623

Fixed a bug where a variable could not be formatted in a summary if its datatype already had a custom format Fixed a bug where Objective-C variables coming out of the expression parser could crash the Python synthetic providers: - expression parser output has a "frozen data" component, which is a byte-exact copy of the value (in host memory), if trying to read into memory based on the host address, LLDB would crash. we are now passing the correct (target) pointer to the Python code Objective-C "id" variables are now formatted according to their dynamic type, if the -d option to frame variable is used: - Code based on the Objective-C 2.0 runtime is used to obtain this information without running code on the target llvm-svn: 136695

Updated the lldb_private::Flags class to have better method names and made all of the calls inlined in the header file for better performance. Fixed the summary for C string types (array of chars (with any combo if modifiers), and pointers to chars) work in all cases. Fixed an issue where a forward declaration to a clang type could cause itself to resolve itself more than once if, during the resolving of the type itself it caused something to try and resolve itself again. We now remove the clang type from the forward declaration map in the DWARF parser when we start to resolve it and avoid this additional call. This should stop any duplicate members from appearing and throwing all the alignment of structs, unions and classes. llvm-svn: 117437

Path from Ashok Thirumurthi: The attached patch adds eValueTypeVector to lldb_private::Value. The nested struct Vector is patterned after RegisterValue::m_data.buffer. This change to Value allows ClangExpressionDeclMap::LookupDecl to return vector register data for consumption by InterpreterStackFrame::ResolveValue. Note that ResolveValue was tweaked slightly to allocate enough memory for vector registers. An immediate result of this patch is that "expr $xmm0" generates the same results on Linux as on the Mac, which is good enough for TestRegisters.py. In addition, the log of m_memory.PrintData(data_region.m_base, data_region.m_extent) shows that the register content has been resolved successfully. On the other hand, the output is glaringly empty: runCmd: expr $xmm0 output: (unsigned char __attribute__((ext_vector_type(16)))) $0 = {} Expecting sub string: vector_type Matched llvm-svn: 167033

<rdar://problem/13069948> Major fixed to allow reading files that are over 4GB. The main problems were that the DataExtractor was using 32 bit offsets as a data cursor, and since we mmap all of our object files we could run into cases where if we had a very large core file that was over 4GB, we were running into the 4GB boundary. So I defined a new "lldb::offset_t" which should be used for all file offsets. After making this change, I enabled warnings for data loss and for enexpected implicit conversions temporarily and found a ton of things that I fixed. Any functions that take an index internally, should use "size_t" for any indexes and also should return "size_t" for any sizes of collections. llvm-svn: 173463

Modified LLDB expressions to not have to JIT and run code just to see variable values or persistent expression variables. Now if an expression consists of a value that is a child of a variable, or of a persistent variable only, we will create a value object for it and make a ValueObjectConstResult from it to freeze the value (for program variables only, not persistent variables) and avoid running JITed code. For everything else we still parse up and JIT code and run it in the inferior. There was also a lot of clean up in the expression code. I made the ClangExpressionVariables be stored in collections of shared pointers instead of in collections of objects. This will help stop a lot of copy constructors on these large objects and also cleans up the code considerably. The persistent clang expression variables were moved over to the Target to ensure they persist across process executions. Added the ability for lldb_private::Target objects to evaluate expressions. We want to evaluate expressions at the target level in case we aren't running yet, or we have just completed running. We still want to be able to access the persistent expression variables between runs, and also evaluate constant expressions. Added extra logging to the dynamic loader plug-in for MacOSX. ModuleList objects can now dump their contents with the UUID, arch and full paths being logged with appropriate prefix values. Thread hardened the Communication class a bit by making the connection auto_ptr member into a shared pointer member and then making a local copy of the shared pointer in each method that uses it to make sure another thread can't nuke the connection object while it is being used by another thread. Added a new file to the lldb/test/load_unload test that causes the test a.out file to link to the libd.dylib file all the time. This will allow us to test using the DYLD_LIBRARY_PATH environment variable after moving libd.dylib somewhere else. llvm-svn: 121745

Huge change to clean up types. A long time ago we start with clang types that were created by the symbol files and there were many functions in lldb_private::ClangASTContext that helped. Later we create ClangASTType which contains a clang::ASTContext and an opauque QualType, but we didn't switch over to fully using it. There were a lot of places where we would pass around a raw clang_type_t and also pass along a clang::ASTContext separately. This left room for error. This checkin change all type code over to use ClangASTType everywhere and I cleaned up the interfaces quite a bit. Any code that was in ClangASTContext that was type related, was moved over into ClangASTType. All code that used these types was switched over to use all of the new goodness. llvm-svn: 186130

Path from Ashok Thirumurthi: The attached patch adds eValueTypeVector to lldb_private::Value. The nested struct Vector is patterned after RegisterValue::m_data.buffer. This change to Value allows ClangExpressionDeclMap::LookupDecl to return vector register data for consumption by InterpreterStackFrame::ResolveValue. Note that ResolveValue was tweaked slightly to allocate enough memory for vector registers. An immediate result of this patch is that "expr $xmm0" generates the same results on Linux as on the Mac, which is good enough for TestRegisters.py. In addition, the log of m_memory.PrintData(data_region.m_base, data_region.m_extent) shows that the register content has been resolved successfully. On the other hand, the output is glaringly empty: runCmd: expr $xmm0 output: (unsigned char __attribute__((ext_vector_type(16)))) $0 = {} Expecting sub string: vector_type Matched llvm-svn: 167033

Introduce the concept of a "display name" for types Rationale: Pretty simply, the idea is that sometimes type names are way too long and contain way too many details for the average developer to care about. For instance, a plain ol' vector of int might be shown as std::__1::vector<int, std::__1::allocator<.... rather than the much simpler std::vector<int> form, which is what most developers would actually type in their code Proposed solution: Introduce a notion of "display name" and a corresponding API GetDisplayTypeName() to return such a crafted for visual representation type name Obviously, the display name and the fully qualified (or "true") name are not necessarily the same - that's the whole point LLDB could choose to pick the "display name" as its one true notion of a type name, and if somebody really needs the fully qualified version of it, let them deal with the problem Or, LLDB could rename what it currently calls the "type name" to be the "display name", and add new APIs for the fully qualified name, making the display name the default choice The choice that I am making here is that the type name will keep meaning the same, and people who want a type name suited for display will explicitly ask for one It is the less risky/disruptive choice - and it should eventually make it fairly obvious when someone is asking for the wrong type Caveats: - for now, GetDisplayTypeName() == GetTypeName(), there is no logic to produce customized display type names yet. - while the fully-qualified type name is still the main key to the kingdom of data formatters, if we start showing custom names to people, those should match formatters llvm-svn: 209072

Updated the lldb_private::Flags class to have better method names and made all of the calls inlined in the header file for better performance. Fixed the summary for C string types (array of chars (with any combo if modifiers), and pointers to chars) work in all cases. Fixed an issue where a forward declaration to a clang type could cause itself to resolve itself more than once if, during the resolving of the type itself it caused something to try and resolve itself again. We now remove the clang type from the forward declaration map in the DWARF parser when we start to resolve it and avoid this additional call. This should stop any duplicate members from appearing and throwing all the alignment of structs, unions and classes. llvm-svn: 117437

Introduce the notion of "runtime support values" A runtime support value is a ValueObject whose only purpose is to support some language runtime's operation, but it does not directly provide any user-visible benefit As such, unless the user is working on the runtime support, it is mostly safe for them not to see such a value when debugging It is a language runtime's job to check whether a ValueObject is a support value, and that - in conjunction with a target setting - is used by frame variable and target variable SBFrame::GetVariables gets a new overload with yet another flag to dictate whether to return those support values to the caller - that which defaults to the setting's value rdar://problem/15539930 llvm-svn: 228791

Huge change to clean up types. A long time ago we start with clang types that were created by the symbol files and there were many functions in lldb_private::ClangASTContext that helped. Later we create ClangASTType which contains a clang::ASTContext and an opauque QualType, but we didn't switch over to fully using it. There were a lot of places where we would pass around a raw clang_type_t and also pass along a clang::ASTContext separately. This left room for error. This checkin change all type code over to use ClangASTType everywhere and I cleaned up the interfaces quite a bit. Any code that was in ClangASTContext that was type related, was moved over into ClangASTType. All code that used these types was switched over to use all of the new goodness. llvm-svn: 186130

Redesign of the interaction between Python and frozen objects: - introduced two new classes ValueObjectConstResultChild and ValueObjectConstResultImpl: the first one is a ValueObjectChild obtained from a ValueObjectConstResult, the second is a common implementation backend for VOCR and VOCRCh of method calls meant to read through pointers stored in frozen objects ; now such reads transparently move from host to target as required - as a consequence of the above, removed code that made target-memory copies of expression results in several places throughout LLDB, and also removed code that enabled to recognize an expression result VO as such - introduced a new GetPointeeData() method in ValueObject that lets you read a given amount of objects of type T from a VO representing a T* or T[], and doing dereferences transparently in private layer it returns a DataExtractor ; in public layer it returns an instance of a newly created lldb::SBData - as GetPointeeData() does the right thing for both frozen and non-frozen ValueObject's, reimplemented ReadPointedString() to use it en lieu of doing the raw read itself - introduced a new GetData() method in ValueObject that lets you get a copy of the data that backs the ValueObject (for pointers, this returns the address without any previous dereferencing steps ; for arrays it actually reads the whole chunk of memory) in public layer this returns an SBData, just like GetPointeeData() - introduced a new CreateValueFromData() method in SBValue that lets you create a new SBValue from a chunk of data wrapped in an SBData the limitation to remember for this kind of SBValue is that they have no address: extracting the address-of for these objects (with any of GetAddress(), GetLoadAddress() and AddressOf()) will return invalid values - added several tests to check that "p"-ing objects (STL classes, char* and char[]) will do the right thing Solved a bug where global pointers to global variables were not dereferenced correctly for display New target setting "max-string-summary-length" gives the maximum number of characters to show in a string when summarizing it, instead of the hardcoded 128 Solved a bug where the summary for char[] and char* would not be shown if the ValueObject's were dumped via the "p" command Removed m_pointers_point_to_load_addrs from ValueObject. Introduced a new m_address_type_of_children, which each ValueObject can set to tell the address type of any pointers and/or references it creates. In the current codebase, this is load address most of the time (the only notable exception being file addresses that generate file address children UNLESS we have a live process) Updated help text for summary-string Fixed an issue in STL formatters where std::stlcontainer::iterator would match the container's synthetic children providers Edited the syntax and help for some commands to have proper argument types llvm-svn: 139160

There is no call to go from non-synthetic to synthetic. The test suite has been changed accordingly.

Synthetic values are now automatically enabled and active by default. SBValue is set up to always wrap a synthetic value when one is available. A new setting enable-synthetic-value is provided on the target to disable this behavior. There also is a new GetNonSyntheticValue() API call on SBValue to go back from synthetic to non-synthetic. There is no call to go from non-synthetic to synthetic. The test suite has been changed accordingly. Fallout from changes to type searching: an hack has to be played to make it possible to use maps that contain std::string due to the special name replacement operated by clang Fixing a test case that was using libstdcpp instead of libc++ - caught as a consequence of said changes to type searching llvm-svn: 153495

<rdar://problem/12437442> Given our implementation of ValueObjects we could have a scenario where a ValueObject has a dynamic type of Foo* at one point, and then its dynamic type changes to Bar* If Bar* has synthetic children enabled, by the time we figure that out, our public API is already vending SBValues wrapping a DynamicVO, instead of a SyntheticVO and there was no trivial way for us to change the SP inside an SBValue on the fly This checkin reimplements SBValue in terms of a wrapper, ValueImpl, that allows this substitutions on-the-fly by overriding GetSP() to do The Right Thing (TM) As an additional bonus, GetNonSyntheticValue() now works, and we can get rid of the ForceDisableSyntheticChildren idiom in ScriptInterpreterPython Lastly, this checkin makes sure the synthetic VOs get the correct m_value and m_data from their parents (prevented summaries from working in some cases) llvm-svn: 166426

<rdar://problem/12978143> Data formatters now cache themselves. This commit provides a new formatter cache mechanism. Upon resolving a formatter (summary or synthetic), LLDB remembers the resolution for later faster retrieval. Also moved the data formatters subsystem from the core to its own group and folder for easier management, and done some code reorganization. The ObjC runtime v1 now returns a class name if asked for the dynamic type of an object. This is required for formatters caching to work with the v1 runtime. Lastly, this commit disposes of the old hack where ValueObjects had to remember whether they were queried for formatters with their static or dynamic type. Now the ValueObjectDynamicValue class works well enough that we can use its dynamic value setting for the same purpose. llvm-svn: 173728

This checking is part one of trying to add some threading safety to our internals. The first part of this is to use a new class: lldb_private::ExecutionContextRef This class holds onto weak pointers to the target, process, thread and frame and it also contains the thread ID and frame Stack ID in case the thread and frame objects go away and come back as new objects that represent the same logical thread/frame. ExecutionContextRef objcets have accessors to access shared pointers for the target, process, thread and frame which might return NULL if the backing object is no longer available. This allows for references to persistent program state without needing to hold a shared pointer to each object and potentially keeping that object around for longer than it needs to be. You can also "Lock" and ExecutionContextRef (which contains weak pointers) object into an ExecutionContext (which contains strong, or shared pointers) with code like ExecutionContext exe_ctx (my_obj->GetExectionContextRef().Lock()); llvm-svn: 150801

when typing a summary string you can use the %S symbol to explicitly indicate that you want the summary to be used to print the target object (e.g. ${var%S}). this might already be the default if your variable is of an aggregate type new feature: synthetic filters. you can restrict the number of children for your variables to only a meaningful subset - the restricted list of children obeys the typical rules (e.g. summaries prevail over children) - one-line summaries show only the filtered (synthetic) children, if you type an expanded summary string, or you use Python scripts, all the real children are accessible - to provide a synthetic children list use the "type synth add" command, as in: type synth add foo_type --child varA --child varB[0] --child varC->packet->flags[1-4] (you can use ., ->, single-item array operator [N] and bitfield operator [N-M]; array slice access is not supported, giving simplified names to expression paths is not supported) - a new -S option to frame variable and target variable lets you override synthetic children and instead show real ones llvm-svn: 135731

<rdar://problem/12978143> Data formatters now cache themselves. This commit provides a new formatter cache mechanism. Upon resolving a formatter (summary or synthetic), LLDB remembers the resolution for later faster retrieval. Also moved the data formatters subsystem from the core to its own group and folder for easier management, and done some code reorganization. The ObjC runtime v1 now returns a class name if asked for the dynamic type of an object. This is required for formatters caching to work with the v1 runtime. Lastly, this commit disposes of the old hack where ValueObjects had to remember whether they were queried for formatters with their static or dynamic type. Now the ValueObjectDynamicValue class works well enough that we can use its dynamic value setting for the same purpose. llvm-svn: 173728

1) solving a bug where, after Jim's fixes to stack frames, synthetic children were not recalculated when necessary, causing them to get out of sync with live data 2) providing an updated list of tagged pointers values for the objc_runtime module - hopefully this one is final 3) changing ValueObject::DumpValueObject to use an Options class instead of providing a bulky list of parameters to pass around this change had been laid out previously, but some clients of DumpValueObject() were still using the old prototype and some arguments were treated in a special way and passed in directly instead of through the Options class 4) providing new GetSummaryAsCString() and GetValueAsCString() calls in ValueObject that are passed a formatter object and a destination string and fill the string by formatting themselves using the formatter argument instead of the default for the current ValueObject 5) removing the option to have formats and summaries stick to a variable for the current stoppoint after some debate, we are going with non-sticky: if you say frame variable --format hex foo, the hex format will only be applied to the current command execution and not stick when redisplaying foo the other option would be full stickiness, which means that foo would be formatted as hex for its whole lifetime we are open to suggestions on what feels "natural" in this regard llvm-svn: 151801

Huge change to clean up types. A long time ago we start with clang types that were created by the symbol files and there were many functions in lldb_private::ClangASTContext that helped. Later we create ClangASTType which contains a clang::ASTContext and an opauque QualType, but we didn't switch over to fully using it. There were a lot of places where we would pass around a raw clang_type_t and also pass along a clang::ASTContext separately. This left room for error. This checkin change all type code over to use ClangASTType everywhere and I cleaned up the interfaces quite a bit. Any code that was in ClangASTContext that was type related, was moved over into ClangASTType. All code that used these types was switched over to use all of the new goodness. llvm-svn: 186130

Added a new ValueObject type that will be used to freeze dry expression results. The clang opaque type for the expression result will be added to the Target's ASTContext, and the bytes will be stored in a DataBuffer inside the new object. The class is named: ValueObjectConstResult Now after an expression is evaluated, we can get a ValueObjectSP back that contains a ValueObjectConstResult object. Relocated the value object dumping code into a static function within the ValueObject class instead of being in the CommandObjectFrame.cpp file which is what contained the code to dump variables ("frame variables"). llvm-svn: 115578

Fixed an expression parsing issue where if you were stopped somewhere without debug information and you evaluated an expression, a crash would occur as a result of an unchecked pointer. Added the ability to get the expression path for a ValueObject. For a rectangle point child "x" the expression path would be something like: "rect.top_left.x". This will allow GUI and command lines to get ahold of the expression path for a value object without having to explicitly know about the hierarchy. This means the ValueObject base class now has a "ValueObject *m_parent;" member. All ValueObject subclasses now correctly track their lineage and are able to provide value expression paths as well. Added a new "--flat" option to the "frame variable" to allow for flat variable output. An example of the current and new outputs: (lldb) frame variable argc = 1 argv = 0x00007fff5fbffe80 pt = { x = 2 y = 3 } rect = { bottom_left = { x = 1 y = 2 } top_right = { x = 3 y = 4 } } (lldb) frame variable --flat argc = 1 argv = 0x00007fff5fbffe80 pt.x = 2 pt.y = 3 rect.bottom_left.x = 1 rect.bottom_left.y = 2 rect.top_right.x = 3 rect.top_right.y = 4 As you can see when there is a lot of hierarchy it can help flatten things out. Also if you want to use a member in an expression, you can copy the text from the "--flat" output and not have to piece it together manually. This can help when you want to use parts of the STL in expressions: (lldb) frame variable --flat argc = 1 argv = 0x00007fff5fbffea8 hello_world._M_dataplus._M_p = 0x0000000000000000 (lldb) expr hello_world._M_dataplus._M_p[0] == '\0' llvm-svn: 116532

Extend ValueObject::GetExpressionPath() to do something reasonable for synthetic children Because of the way they are created, synthetic children cannot (in general) have a sane expression path A solution to this would be letting the parent front-end generate expression paths for its children Doing so requires a significant amount of refactoring, and might not always lead to better results (esp. w.r.t. C++ templates) This commit takes a simpler approach: - if a synthetic child is of pointer type and it's a target pointer, then emit *((T)value) - if a synthetic child is a non-pointer, but its location is in the target, then emit *((T*)loadAddr) - if a synthetic child has a value, emit ((T)value) - else, don't emit anything Fixes rdar://18442386 llvm-svn: 223836

Fixed an expression parsing issue where if you were stopped somewhere without debug information and you evaluated an expression, a crash would occur as a result of an unchecked pointer. Added the ability to get the expression path for a ValueObject. For a rectangle point child "x" the expression path would be something like: "rect.top_left.x". This will allow GUI and command lines to get ahold of the expression path for a value object without having to explicitly know about the hierarchy. This means the ValueObject base class now has a "ValueObject *m_parent;" member. All ValueObject subclasses now correctly track their lineage and are able to provide value expression paths as well. Added a new "--flat" option to the "frame variable" to allow for flat variable output. An example of the current and new outputs: (lldb) frame variable argc = 1 argv = 0x00007fff5fbffe80 pt = { x = 2 y = 3 } rect = { bottom_left = { x = 1 y = 2 } top_right = { x = 3 y = 4 } } (lldb) frame variable --flat argc = 1 argv = 0x00007fff5fbffe80 pt.x = 2 pt.y = 3 rect.bottom_left.x = 1 rect.bottom_left.y = 2 rect.top_right.x = 3 rect.top_right.y = 4 As you can see when there is a lot of hierarchy it can help flatten things out. Also if you want to use a member in an expression, you can copy the text from the "--flat" output and not have to piece it together manually. This can help when you want to use parts of the STL in expressions: (lldb) frame variable --flat argc = 1 argv = 0x00007fff5fbffea8 hello_world._M_dataplus._M_p = 0x0000000000000000 (lldb) expr hello_world._M_dataplus._M_p[0] == '\0' llvm-svn: 116532

Huge change to clean up types. A long time ago we start with clang types that were created by the symbol files and there were many functions in lldb_private::ClangASTContext that helped. Later we create ClangASTType which contains a clang::ASTContext and an opauque QualType, but we didn't switch over to fully using it. There were a lot of places where we would pass around a raw clang_type_t and also pass along a clang::ASTContext separately. This left room for error. This checkin change all type code over to use ClangASTType everywhere and I cleaned up the interfaces quite a bit. Any code that was in ClangASTContext that was type related, was moved over into ClangASTType. All code that used these types was switched over to use all of the new goodness. llvm-svn: 186130

Second round of code cleanups: - reorganizing classes layout to have public part first Typedefs that we want to keep private, but must be defined for some public code to work correctly are an exception - avoiding methods in the form T foo() { code; } all on one-line - moving method implementations from .h to .cpp whenever feasible Templatized code is an exception and so are very small methods - generally, adhering to coding conventions followed project-wide Functional changes: - fixed an issue where using ${var} in a summary for an aggregate, and then displaying a pointer-to-aggregate would lead to no summary being displayed The issue was not a major one because all ${var} was meant to do in that context was display an error for invalid use of pointer Accordingly fixed test cases and added a new test case llvm-svn: 137944

Huge change to clean up types. A long time ago we start with clang types that were created by the symbol files and there were many functions in lldb_private::ClangASTContext that helped. Later we create ClangASTType which contains a clang::ASTContext and an opauque QualType, but we didn't switch over to fully using it. There were a lot of places where we would pass around a raw clang_type_t and also pass along a clang::ASTContext separately. This left room for error. This checkin change all type code over to use ClangASTType everywhere and I cleaned up the interfaces quite a bit. Any code that was in ClangASTContext that was type related, was moved over into ClangASTType. All code that used these types was switched over to use all of the new goodness. llvm-svn: 186130

Fixed the global and static variables to always be in scope. Made it so that you can create synthetic children of array value objects.

Huge change to clean up types. A long time ago we start with clang types that were created by the symbol files and there were many functions in lldb_private::ClangASTContext that helped. Later we create ClangASTType which contains a clang::ASTContext and an opauque QualType, but we didn't switch over to fully using it. There were a lot of places where we would pass around a raw clang_type_t and also pass along a clang::ASTContext separately. This left room for error. This checkin change all type code over to use ClangASTType everywhere and I cleaned up the interfaces quite a bit. Any code that was in ClangASTContext that was type related, was moved over into ClangASTType. All code that used these types was switched over to use all of the new goodness. llvm-svn: 186130

<rdar://problem/11113279> Fixed type lookups to "do the right thing". Prior to this fix, looking up a type using "foo::bar" would result in a type list that contains all types that had "bar" as a basename unless the symbol file was able to match fully qualified names (which our DWARF parser does not). This fix will allow type matches to be made based on the basename and then have the types that don't match filtered out. Types by name can be fully qualified, or partially qualified with the new "bool exact_match" parameter to the Module::FindTypes() method. This fixes some issue that we discovered with dynamic type resolution as well as improves the overall type lookups in LLDB. llvm-svn: 153482

<rdar://problem/13069948> Major fixed to allow reading files that are over 4GB. The main problems were that the DataExtractor was using 32 bit offsets as a data cursor, and since we mmap all of our object files we could run into cases where if we had a very large core file that was over 4GB, we were running into the 4GB boundary. So I defined a new "lldb::offset_t" which should be used for all file offsets. After making this change, I enabled warnings for data loss and for enexpected implicit conversions temporarily and found a ton of things that I fixed. Any functions that take an index internally, should use "size_t" for any indexes and also should return "size_t" for any sizes of collections. llvm-svn: 173463

Modified LLDB expressions to not have to JIT and run code just to see variable values or persistent expression variables. Now if an expression consists of a value that is a child of a variable, or of a persistent variable only, we will create a value object for it and make a ValueObjectConstResult from it to freeze the value (for program variables only, not persistent variables) and avoid running JITed code. For everything else we still parse up and JIT code and run it in the inferior. There was also a lot of clean up in the expression code. I made the ClangExpressionVariables be stored in collections of shared pointers instead of in collections of objects. This will help stop a lot of copy constructors on these large objects and also cleans up the code considerably. The persistent clang expression variables were moved over to the Target to ensure they persist across process executions. Added the ability for lldb_private::Target objects to evaluate expressions. We want to evaluate expressions at the target level in case we aren't running yet, or we have just completed running. We still want to be able to access the persistent expression variables between runs, and also evaluate constant expressions. Added extra logging to the dynamic loader plug-in for MacOSX. ModuleList objects can now dump their contents with the UUID, arch and full paths being logged with appropriate prefix values. Thread hardened the Communication class a bit by making the connection auto_ptr member into a shared pointer member and then making a local copy of the shared pointer in each method that uses it to make sure another thread can't nuke the connection object while it is being used by another thread. Added a new file to the lldb/test/load_unload test that causes the test a.out file to link to the libd.dylib file all the time. This will allow us to test using the DYLD_LIBRARY_PATH environment variable after moving libd.dylib somewhere else. llvm-svn: 121745

This checking is part one of trying to add some threading safety to our internals. The first part of this is to use a new class: lldb_private::ExecutionContextRef This class holds onto weak pointers to the target, process, thread and frame and it also contains the thread ID and frame Stack ID in case the thread and frame objects go away and come back as new objects that represent the same logical thread/frame. ExecutionContextRef objcets have accessors to access shared pointers for the target, process, thread and frame which might return NULL if the backing object is no longer available. This allows for references to persistent program state without needing to hold a shared pointer to each object and potentially keeping that object around for longer than it needs to be. You can also "Lock" and ExecutionContextRef (which contains weak pointers) object into an ExecutionContext (which contains strong, or shared pointers) with code like ExecutionContext exe_ctx (my_obj->GetExectionContextRef().Lock()); llvm-svn: 150801

Huge change to clean up types. A long time ago we start with clang types that were created by the symbol files and there were many functions in lldb_private::ClangASTContext that helped. Later we create ClangASTType which contains a clang::ASTContext and an opauque QualType, but we didn't switch over to fully using it. There were a lot of places where we would pass around a raw clang_type_t and also pass along a clang::ASTContext separately. This left room for error. This checkin change all type code over to use ClangASTType everywhere and I cleaned up the interfaces quite a bit. Any code that was in ClangASTContext that was type related, was moved over into ClangASTType. All code that used these types was switched over to use all of the new goodness. llvm-svn: 186130

Later we create ClangASTType which contains a clang::ASTContext and an opauque QualType, but we didn't switch over to fully using it. There were a lot of places where we would pass around a raw clang_type_t and also pass along a clang::ASTContext separately. This left room for error. This checkin change all type code over to use ClangASTType everywhere and I cleaned up the interfaces quite a bit. Any code that was in ClangASTContext that was type related, was moved over into ClangASTType. All code that used these types was switched over to use all of the new goodness. llvm-svn: 186130

This checking is part one of trying to add some threading safety to our internals. The first part of this is to use a new class: lldb_private::ExecutionContextRef This class holds onto weak pointers to the target, process, thread and frame and it also contains the thread ID and frame Stack ID in case the thread and frame objects go away and come back as new objects that represent the same logical thread/frame. ExecutionContextRef objcets have accessors to access shared pointers for the target, process, thread and frame which might return NULL if the backing object is no longer available. This allows for references to persistent program state without needing to hold a shared pointer to each object and potentially keeping that object around for longer than it needs to be. You can also "Lock" and ExecutionContextRef (which contains weak pointers) object into an ExecutionContext (which contains strong, or shared pointers) with code like ExecutionContext exe_ctx (my_obj->GetExectionContextRef().Lock()); llvm-svn: 150801

Modified LLDB expressions to not have to JIT and run code just to see variable values or persistent expression variables. Now if an expression consists of a value that is a child of a variable, or of a persistent variable only, we will create a value object for it and make a ValueObjectConstResult from it to freeze the value (for program variables only, not persistent variables) and avoid running JITed code. For everything else we still parse up and JIT code and run it in the inferior. There was also a lot of clean up in the expression code. I made the ClangExpressionVariables be stored in collections of shared pointers instead of in collections of objects. This will help stop a lot of copy constructors on these large objects and also cleans up the code considerably. The persistent clang expression variables were moved over to the Target to ensure they persist across process executions. Added the ability for lldb_private::Target objects to evaluate expressions. We want to evaluate expressions at the target level in case we aren't running yet, or we have just completed running. We still want to be able to access the persistent expression variables between runs, and also evaluate constant expressions. Added extra logging to the dynamic loader plug-in for MacOSX. ModuleList objects can now dump their contents with the UUID, arch and full paths being logged with appropriate prefix values. Thread hardened the Communication class a bit by making the connection auto_ptr member into a shared pointer member and then making a local copy of the shared pointer in each method that uses it to make sure another thread can't nuke the connection object while it is being used by another thread. Added a new file to the lldb/test/load_unload test that causes the test a.out file to link to the libd.dylib file all the time. This will allow us to test using the DYLD_LIBRARY_PATH environment variable after moving libd.dylib somewhere else. llvm-svn: 121745

Convert ValueObject to explicitly maintain the Execution Context in which they were created, and then use that when they update themselves. That means all the ValueObject evaluate me type functions that used to require a Frame object now do not. I didn't remove the SBValue API's that take this now useless frame, but I added ones that don't require the frame, and marked the SBFrame taking ones as deprecated. llvm-svn: 128593

Add support for "dynamic values" for C++ classes. This currently only works for "frame var" and for the expressions that are simple enough to get passed to the "frame var" underpinnings. The parser code will have to be changed to also query for the dynamic types & offsets as it is looking up variables. The behavior of "frame var" is controlled in two ways. You can pass "-d {true/false} to the frame var command to get the dynamic or static value of the variables you are printing. There's also a general setting: target.prefer-dynamic-value (boolean) = 'true' which is consulted if you call "frame var" without supplying a value for the -d option. llvm-svn: 129623

Fixed the global and static variables to always be in scope. Made it so that you can create synthetic children of array value objects. This is for creating array members when the array index is out of range. This comes in handy when you have a structure definition like: struct Collection { uint32_t count; Item array[0]; }; "array" has 1 item, but many times in practice there are more items in "item_array". This allows you to do: (lldb) target variable g_collection.array[3] To implement this, the get child at index has been modified to have a "ignore_array_bounds" boolean that can be set to true. llvm-svn: 134846

Put more smarts into the RegisterContext base class. Now the base class has a method: void RegisterContext::InvalidateIfNeeded (bool force); Each time this function is called, when "force" is false, it will only call the pure virtual "virtual void RegisterContext::InvalideAllRegisters()" if the register context's stop ID doesn't match that of the process. When the stop ID doesn't match, or "force" is true, the base class will clear its cached registers and the RegisterContext will update its stop ID to match that of the process. This helps make it easier to correctly flush the register context (possibly from multiple locations depending on when and where new registers are availabe) without inadvertently clearing the register cache when it doesn't need to be. Modified the ProcessGDBRemote plug-in to be much more efficient when it comes to: - caching the expedited registers in the stop reply packets (we were ignoring these before and it was causing us to read at least three registers every time we stopped that were already supplied in the stop reply packet). - When a thread has no stop reason, don't keep asking for the thread stopped info. Prior to this fix we would continually send a qThreadStopInfo packet over and over when any thread stop info was requested. We now note the stop ID that the stop info was requested for and avoid multiple requests. Cleaned up some of the expression code to not look for ClangExpressionVariable objects up by name since they are now shared pointers and we can just look for the exact pointer match and avoid possible errors.

Redesign of the interaction between Python and frozen objects: - introduced two new classes ValueObjectConstResultChild and ValueObjectConstResultImpl: the first one is a ValueObjectChild obtained from a ValueObjectConstResult, the second is a common implementation backend for VOCR and VOCRCh of method calls meant to read through pointers stored in frozen objects ; now such reads transparently move from host to target as required - as a consequence of the above, removed code that made target-memory copies of expression results in several places throughout LLDB, and also removed code that enabled to recognize an expression result VO as such - introduced a new GetPointeeData() method in ValueObject that lets you read a given amount of objects of type T from a VO representing a T* or T[], and doing dereferences transparently in private layer it returns a DataExtractor ; in public layer it returns an instance of a newly created lldb::SBData - as GetPointeeData() does the right thing for both frozen and non-frozen ValueObject's, reimplemented ReadPointedString() to use it en lieu of doing the raw read itself - introduced a new GetData() method in ValueObject that lets you get a copy of the data that backs the ValueObject (for pointers, this returns the address without any previous dereferencing steps ; for arrays it actually reads the whole chunk of memory) in public layer this returns an SBData, just like GetPointeeData() - introduced a new CreateValueFromData() method in SBValue that lets you create a new SBValue from a chunk of data wrapped in an SBData the limitation to remember for this kind of SBValue is that they have no address: extracting the address-of for these objects (with any of GetAddress(), GetLoadAddress() and AddressOf()) will return invalid values - added several tests to check that "p"-ing objects (STL classes, char* and char[]) will do the right thing Solved a bug where global pointers to global variables were not dereferenced correctly for display New target setting "max-string-summary-length" gives the maximum number of characters to show in a string when summarizing it, instead of the hardcoded 128 Solved a bug where the summary for char[] and char* would not be shown if the ValueObject's were dumped via the "p" command Removed m_pointers_point_to_load_addrs from ValueObject. Introduced a new m_address_type_of_children, which each ValueObject can set to tell the address type of any pointers and/or references it creates. In the current codebase, this is load address most of the time (the only notable exception being file addresses that generate file address children UNLESS we have a live process) Updated help text for summary-string Fixed an issue in STL formatters where std::stlcontainer::iterator would match the container's synthetic children providers Edited the syntax and help for some commands to have proper argument types llvm-svn: 139160

Modified LLDB expressions to not have to JIT and run code just to see variable values or persistent expression variables. Now if an expression consists of a value that is a child of a variable, or of a persistent variable only, we will create a value object for it and make a ValueObjectConstResult from it to freeze the value (for program variables only, not persistent variables) and avoid running JITed code. For everything else we still parse up and JIT code and run it in the inferior. There was also a lot of clean up in the expression code. I made the ClangExpressionVariables be stored in collections of shared pointers instead of in collections of objects. This will help stop a lot of copy constructors on these large objects and also cleans up the code considerably. The persistent clang expression variables were moved over to the Target to ensure they persist across process executions. Added the ability for lldb_private::Target objects to evaluate expressions. We want to evaluate expressions at the target level in case we aren't running yet, or we have just completed running. We still want to be able to access the persistent expression variables between runs, and also evaluate constant expressions. Added extra logging to the dynamic loader plug-in for MacOSX. ModuleList objects can now dump their contents with the UUID, arch and full paths being logged with appropriate prefix values. Thread hardened the Communication class a bit by making the connection auto_ptr member into a shared pointer member and then making a local copy of the shared pointer in each method that uses it to make sure another thread can't nuke the connection object while it is being used by another thread. Added a new file to the lldb/test/load_unload test that causes the test a.out file to link to the libd.dylib file all the time. This will allow us to test using the DYLD_LIBRARY_PATH environment variable after moving libd.dylib somewhere else. llvm-svn: 121745

A few of the issue I have been trying to track down and fix have been due to the way LLDB lazily gets complete definitions for types within the debug info. When we run across a class/struct/union definition in the DWARF, we will only parse the full definition if we need to. This works fine for top level types that are assigned directly to variables and arguments, but when we have a variable with a class, lets say "A" for this example, that has a member: "B *m_b". Initially we don't need to hunt down a definition for this class unless we are ever asked to do something with it ("expr m_b->getDecl()" for example). With my previous approach to lazy type completion, we would be able to take a "A *a" and get a complete type for it, but we wouldn't be able to then do an "a->m_b->getDecl()" unless we always expanded all types within a class prior to handing out the type. Expanding everything is very costly and it would be great if there were a better way. A few months ago I worked with the llvm/clang folks to have the ExternalASTSource class be able to complete classes if there weren't completed yet: class ExternalASTSource { .... virtual void CompleteType (clang::TagDecl *Tag); virtual void CompleteType (clang::ObjCInterfaceDecl *Class); }; This was great, because we can now have the class that is producing the AST (SymbolFileDWARF and SymbolFileDWARFDebugMap) sign up as external AST sources and the object that creates the forward declaration types can now also complete them anywhere within the clang type system. This patch makes a few major changes: - lldb_private::Module classes now own the AST context. Previously the TypeList objects did. - The DWARF parsers now sign up as an external AST sources so they can complete types. - All of the pure clang type system wrapper code we have in LLDB (ClangASTContext, ClangASTType, and more) can now be iterating through children of any type, and if a class/union/struct type (clang::RecordType or ObjC interface) is found that is incomplete, we can ask the AST to get the definition. - The SymbolFileDWARFDebugMap class now will create and use a single AST that all child SymbolFileDWARF classes will share (much like what happens when we have a complete linked DWARF for an executable). We will need to modify some of the ClangUserExpression code to take more advantage of this completion ability in the near future. Meanwhile we should be better off now that we can be accessing any children of variables through pointers and always be able to resolve the clang type if needed. llvm-svn: 123613

Add support for "dynamic values" for C++ classes. This currently only works for "frame var" and for the expressions that are simple enough to get passed to the "frame var" underpinnings. The parser code will have to be changed to also query for the dynamic types & offsets as it is looking up variables. The behavior of "frame var" is controlled in two ways. You can pass "-d {true/false} to the frame var command to get the dynamic or static value of the variables you are printing. There's also a general setting: target.prefer-dynamic-value (boolean) = 'true' which is consulted if you call "frame var" without supplying a value for the -d option. llvm-svn: 129623

Modified LLDB expressions to not have to JIT and run code just to see variable values or persistent expression variables. Now if an expression consists of a value that is a child of a variable, or of a persistent variable only, we will create a value object for it and make a ValueObjectConstResult from it to freeze the value (for program variables only, not persistent variables) and avoid running JITed code. For everything else we still parse up and JIT code and run it in the inferior. There was also a lot of clean up in the expression code. I made the ClangExpressionVariables be stored in collections of shared pointers instead of in collections of objects. This will help stop a lot of copy constructors on these large objects and also cleans up the code considerably. The persistent clang expression variables were moved over to the Target to ensure they persist across process executions. Added the ability for lldb_private::Target objects to evaluate expressions. We want to evaluate expressions at the target level in case we aren't running yet, or we have just completed running. We still want to be able to access the persistent expression variables between runs, and also evaluate constant expressions. Added extra logging to the dynamic loader plug-in for MacOSX. ModuleList objects can now dump their contents with the UUID, arch and full paths being logged with appropriate prefix values. Thread hardened the Communication class a bit by making the connection auto_ptr member into a shared pointer member and then making a local copy of the shared pointer in each method that uses it to make sure another thread can't nuke the connection object while it is being used by another thread. Added a new file to the lldb/test/load_unload test that causes the test a.out file to link to the libd.dylib file all the time. This will allow us to test using the DYLD_LIBRARY_PATH environment variable after moving libd.dylib somewhere else. llvm-svn: 121745

Huge change to clean up types. A long time ago we start with clang types that were created by the symbol files and there were many functions in lldb_private::ClangASTContext that helped. Later we create ClangASTType which contains a clang::ASTContext and an opauque QualType, but we didn't switch over to fully using it. There were a lot of places where we would pass around a raw clang_type_t and also pass along a clang::ASTContext separately. This left room for error. This checkin change all type code over to use ClangASTType everywhere and I cleaned up the interfaces quite a bit. Any code that was in ClangASTContext that was type related, was moved over into ClangASTType. All code that used these types was switched over to use all of the new goodness. llvm-svn: 186130

This checking is part one of trying to add some threading safety to our internals. The first part of this is to use a new class: lldb_private::ExecutionContextRef This class holds onto weak pointers to the target, process, thread and frame and it also contains the thread ID and frame Stack ID in case the thread and frame objects go away and come back as new objects that represent the same logical thread/frame. ExecutionContextRef objcets have accessors to access shared pointers for the target, process, thread and frame which might return NULL if the backing object is no longer available. This allows for references to persistent program state without needing to hold a shared pointer to each object and potentially keeping that object around for longer than it needs to be. You can also "Lock" and ExecutionContextRef (which contains weak pointers) object into an ExecutionContext (which contains strong, or shared pointers) with code like ExecutionContext exe_ctx (my_obj->GetExectionContextRef().Lock()); llvm-svn: 150801

Add support for "dynamic values" for C++ classes. This currently only works for "frame var" and for the expressions that are simple enough to get passed to the "frame var" underpinnings. The parser code will have to be changed to also query for the dynamic types & offsets as it is looking up variables. The behavior of "frame var" is controlled in two ways. You can pass "-d {true/false} to the frame var command to get the dynamic or static value of the variables you are printing. There's also a general setting: target.prefer-dynamic-value (boolean) = 'true' which is consulted if you call "frame var" without supplying a value for the -d option. llvm-svn: 129623

Converted the lldb_private::Process over to use the intrusive shared pointers. Changed the ExecutionContext over to use shared pointers for the target, process, thread and frame since these objects can easily go away at any time and any object that was holding onto an ExecutionContext was running the risk of using a bad object. Now that the shared pointers for target, process, thread and frame are just a single pointer (they all use the instrusive shared pointers) the execution context is much safer and still the same size. Made the shared pointers in the the ExecutionContext class protected and made accessors for all of the various ways to get at the pointers, references, and shared pointers. llvm-svn: 140298

This checking is part one of trying to add some threading safety to our internals.

ExecutionContextRef objcets have accessors to access shared pointers for the target, process, thread and frame which might return NULL if the backing object is no longer available. This allows for references to persistent program state without needing to hold a shared pointer to each object and potentially keeping that object around for longer than it needs to be.

Add support for "dynamic values" for C++ classes. This currently only works for "frame var" and for the expressions that are simple enough to get passed to the "frame var" underpinnings. The parser code will have to be changed to also query for the dynamic types & offsets as it is looking up variables. The behavior of "frame var" is controlled in two ways. You can pass "-d {true/false} to the frame var command to get the dynamic or static value of the variables you are printing. There's also a general setting: target.prefer-dynamic-value (boolean) = 'true' which is consulted if you call "frame var" without supplying a value for the -d option. llvm-svn: 129623

Redesign of the interaction between Python and frozen objects: - introduced two new classes ValueObjectConstResultChild and ValueObjectConstResultImpl: the first one is a ValueObjectChild obtained from a ValueObjectConstResult, the second is a common implementation backend for VOCR and VOCRCh of method calls meant to read through pointers stored in frozen objects ; now such reads transparently move from host to target as required - as a consequence of the above, removed code that made target-memory copies of expression results in several places throughout LLDB, and also removed code that enabled to recognize an expression result VO as such - introduced a new GetPointeeData() method in ValueObject that lets you read a given amount of objects of type T from a VO representing a T* or T[], and doing dereferences transparently in private layer it returns a DataExtractor ; in public layer it returns an instance of a newly created lldb::SBData - as GetPointeeData() does the right thing for both frozen and non-frozen ValueObject's, reimplemented ReadPointedString() to use it en lieu of doing the raw read itself - introduced a new GetData() method in ValueObject that lets you get a copy of the data that backs the ValueObject (for pointers, this returns the address without any previous dereferencing steps ; for arrays it actually reads the whole chunk of memory) in public layer this returns an SBData, just like GetPointeeData() - introduced a new CreateValueFromData() method in SBValue that lets you create a new SBValue from a chunk of data wrapped in an SBData the limitation to remember for this kind of SBValue is that they have no address: extracting the address-of for these objects (with any of GetAddress(), GetLoadAddress() and AddressOf()) will return invalid values - added several tests to check that "p"-ing objects (STL classes, char* and char[]) will do the right thing Solved a bug where global pointers to global variables were not dereferenced correctly for display New target setting "max-string-summary-length" gives the maximum number of characters to show in a string when summarizing it, instead of the hardcoded 128 Solved a bug where the summary for char[] and char* would not be shown if the ValueObject's were dumped via the "p" command Removed m_pointers_point_to_load_addrs from ValueObject. Introduced a new m_address_type_of_children, which each ValueObject can set to tell the address type of any pointers and/or references it creates. In the current codebase, this is load address most of the time (the only notable exception being file addresses that generate file address children UNLESS we have a live process) Updated help text for summary-string Fixed an issue in STL formatters where std::stlcontainer::iterator would match the container's synthetic children providers Edited the syntax and help for some commands to have proper argument types llvm-svn: 139160

<rdar://problem/13623698> This patch fixes the issue that we were using the C stack as a measure of depth of ValueObject hierarchies, in the sense that we were assuming that recursive ValueObject operations would never be deeper than the stack allows. This assumption is easy to prove wrong, however. For instance, after ~10k runs through this loop: struct node { int value; node* child; node (int x) { value = x; child = nullptr; } }; int main () { node root(1); node* ptr = &root; int j = 2; while (1) { ptr->child = new node(j++); ptr = ptr->child; } return 0; } the deepmost child object will be deeper than the stack on most architectures, and we would be unable to display it This checkin fixes the issue by introducing a notion of root of ValueObject hierarchies. In a couple cases, we have to use an iterative algorithm instead of going to the root because we want to allow deeper customizations (e.g. formats, dynamic values). While the patch passes our test suite without regressions, it is a good idea to keep eyes open for any unexpected behavior (recursion can be subtle..) Also, I am hesitant to introduce a test case since failing at this will not just be marked as an "F", but most definitely crash LLDB. llvm-svn: 179330

Extend synthetic children to produce synthetic values (as in, those that GetValueAsUnsigned(), GetValueAsCString() would return) The way to do this is to write a synthetic child provider for your type, and have it vend the (optional) get_value function. If get_value is defined, and it returns a valid SBValue, that SBValue's value (as in lldb_private::Value) will be used as the synthetic ValueObject's Value The rationale for doing things this way is twofold: - there are many possible ways to define a "value" (SBData, a Python number, ...) but SBValue seems general enough as a thing that stores a "value", so we just trade values that way and that keeps our currency trivial - we could introduce a new level of layering (ValueObjectSyntheticValue), a new kind of formatter (synthetic value producer), but that would complicate the model (can I have a dynamic with no synthetic children but synthetic value? synthetic value with synthetic children but no dynamic?), and I really couldn't see much benefit to be reaped from this added complexity in the matrix On the other hand, just defining a synthetic child provider with a get_value but returning no actual children is easy enough that it's not a significant road-block to adoption of this feature Comes with a test case llvm-svn: 219330

Introduce the notion of "type summary options" as flags that can be passed down to individual summary formatters to alter their behavior in a formatter-dependent way Two flags are introduced: - preferred display language (as in, ObjC vs. C++) - summary capping (as in, should a limit be put to the amount of data retrieved) The meaning - if any - of these options is for individual formatters to establish The topic of a subsequent commit will be to actually wire these through to individual data formatters llvm-svn: 221482

Extend synthetic children to produce synthetic values (as in, those that GetValueAsUnsigned(), GetValueAsCString() would return) The way to do this is to write a synthetic child provider for your type, and have it vend the (optional) get_value function. If get_value is defined, and it returns a valid SBValue, that SBValue's value (as in lldb_private::Value) will be used as the synthetic ValueObject's Value The rationale for doing things this way is twofold: - there are many possible ways to define a "value" (SBData, a Python number, ...) but SBValue seems general enough as a thing that stores a "value", so we just trade values that way and that keeps our currency trivial - we could introduce a new level of layering (ValueObjectSyntheticValue), a new kind of formatter (synthetic value producer), but that would complicate the model (can I have a dynamic with no synthetic children but synthetic value? synthetic value with synthetic children but no dynamic?), and I really couldn't see much benefit to be reaped from this added complexity in the matrix On the other hand, just defining a synthetic child provider with a get_value but returning no actual children is easy enough that it's not a significant road-block to adoption of this feature Comes with a test case llvm-svn: 219330

Fixed ValueObject::UpdateValueIfNeeded to keep track of the checksum of the object so we can track if it is modified. This fixes a testcase (test/expression_command/issue_11588) on OS X. Patch by Enrico Granata. llvm-svn: 223830

Add the ability for an SBValue to create a persisted version of itself. Such a persisted version is equivalent to evaluating the value via the expression evaluator, and holding on to the $n result of the expression, except this API can be used on SBValues that do not obviously come from an expression (e.g. are the result of a memory lookup) Expose this via SBValue::Persist() in our public API layer, and ValueObject::Persist() in the lldb_private layer Includes testcase Fixes rdar://19136664 llvm-svn: 223711

This patch does a few things: - adds a new flag to mark ValueObjects as "synthetic children generated" - vends new Create functions as part of the SyntheticChildrenFrontEnd that set the flag automatically - moves synthetic child providers over to using these new functions No visible feature change, but preparatory work for feature change llvm-svn: 223819
