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

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

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

Change over to using the definitions for mach-o types and defines to the defines that are in "llvm/Support/MachO.h". This should allow ObjectFileMachO and ObjectContainerUniversalMachO to be able to be cross compiled in Linux.

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

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

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 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

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

Fixed a bug where deleting a regex summary would not immediately reflect in the variables display The "systemwide summaries" feature has been removed and replaced with a more general and powerful mechanism. Categories: - summaries can now be grouped into buckets, called "categories" (it is expected that categories correspond to libraries and/or runtime environments) - to add a summary to a category, you can use the -w option to type summary add and give a category name (e.g. type summary add -f "foo" foo_t -w foo_category) - categories are by default disabled, which means LLDB will not look into them for summaries, to enable a category use "type category enable". once a category is enabled, LLDB will look into that category for summaries. the rules are quite trivial: every enabled category is searched for an exact match. if an exact match is nowhere to be found, any match is searched for in every enabled category (whether it involves cascading, going to base classes, ...). categories are searched into the order in which they were enabled (the most recently enabled category first, then the second most and so on..) - by default, most commands that deal with summaries, use a category named "default" if no explicit -w parameter is given (the observable behavior of LLDB should not change when categories are not explicitly used) - the systemwide summaries are now part of a "system" category llvm-svn: 135463

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.

Modified the lldb_private::Type clang type resolving code to handle three cases when getting the clang type: - need only a forward declaration - need a clang type that can be used for layout (members and args/return types) - need a full clang type This allows us to partially parse the clang types and be as lazy as possible. The first case is when we just need to declare a type and we will complete it later. The forward declaration happens only for class/union/structs and enums. The layout type allows us to resolve the full clang type _except_ if we have any modifiers on a pointer or reference (both R and L value). In this case when we are adding members or function args or return types, we only need to know how the type will be laid out and we can defer completing the pointee type until we later need it. The last type means we need a full definition for the clang type. Did some renaming of some enumerations to get rid of the old "DC" prefix (which stands for DebugCore which is no longer around). Modified the clang namespace support to be almost ready to be fed to the expression parser. I made a new ClangNamespaceDecl class that can carry around the AST and the namespace decl so we can copy it into the expression AST. I modified the symbol vendor and symbol file plug-ins to use this new class. llvm-svn: 118976

Added support for loading and unloading shared libraries.

It might also know about the current host system and know where to check to make sure runtime or malloc locks are currently being held.

Fixed the forward declaration issue that was present in the DWARF parser after adding methods to C++ and objective C classes. In order to make methods, we need the function prototype which means we need the arguments. Parsing these could cause a circular reference that caused an assertion. Added a new typedef for the clang opaque types which are just void pointers: lldb::clang_type_t. This appears in lldb-types.h. This was fixed by enabling struct, union, class, and enum types to only get a forward declaration when we make the clang opaque qual type for these types. When they need to actually be resolved, lldb_private::Type will call a new function in the SymbolFile protocol to resolve a clang type when it is not fully defined (clang::TagDecl::getDefinition() returns NULL). This allows us to be a lot more lazy when parsing clang types and keeps down the amount of data that gets parsed into the ASTContext for each module. Getting the clang type from a "lldb_private::Type" object now takes a boolean that indicates if a forward declaration is ok: clang_type_t lldb_private::Type::GetClangType (bool forward_decl_is_ok); So function prototypes that define parameters that are "const T&" can now just parse the forward declaration for type 'T' and we avoid circular references in the type system. llvm-svn: 115012

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

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

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

// If our byte size is zero this is an aggregate type that has children
Fixed the forward declaration issue that was present in the DWARF parser after adding methods to C++ and objective C classes. In order to make methods, we need the function prototype which means we need the arguments. Parsing these could cause a circular reference that caused an assertion. Added a new typedef for the clang opaque types which are just void pointers: lldb::clang_type_t. This appears in lldb-types.h. This was fixed by enabling struct, union, class, and enum types to only get a forward declaration when we make the clang opaque qual type for these types. When they need to actually be resolved, lldb_private::Type will call a new function in the SymbolFile protocol to resolve a clang type when it is not fully defined (clang::TagDecl::getDefinition() returns NULL). This allows us to be a lot more lazy when parsing clang types and keeps down the amount of data that gets parsed into the ASTContext for each module. Getting the clang type from a "lldb_private::Type" object now takes a boolean that indicates if a forward declaration is ok: clang_type_t lldb_private::Type::GetClangType (bool forward_decl_is_ok); So function prototypes that define parameters that are "const T&" can now just parse the forward declaration for type 'T' and we avoid circular references in the type system. llvm-svn: 115012

Modified the lldb_private::Type clang type resolving code to handle three cases when getting the clang type: - need only a forward declaration - need a clang type that can be used for layout (members and args/return types) - need a full clang type This allows us to partially parse the clang types and be as lazy as possible. The first case is when we just need to declare a type and we will complete it later. The forward declaration happens only for class/union/structs and enums. The layout type allows us to resolve the full clang type _except_ if we have any modifiers on a pointer or reference (both R and L value). In this case when we are adding members or function args or return types, we only need to know how the type will be laid out and we can defer completing the pointee type until we later need it. The last type means we need a full definition for the clang type. Did some renaming of some enumerations to get rid of the old "DC" prefix (which stands for DebugCore which is no longer around). Modified the clang namespace support to be almost ready to be fed to the expression parser. I made a new ClangNamespaceDecl class that can carry around the AST and the namespace decl so we can copy it into the expression AST. I modified the symbol vendor and symbol file plug-ins to use this new class. llvm-svn: 118976

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

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

Modified the lldb_private::Type clang type resolving code to handle three cases when getting the clang type: - need only a forward declaration - need a clang type that can be used for layout (members and args/return types) - need a full clang type This allows us to partially parse the clang types and be as lazy as possible. The first case is when we just need to declare a type and we will complete it later. The forward declaration happens only for class/union/structs and enums. The layout type allows us to resolve the full clang type _except_ if we have any modifiers on a pointer or reference (both R and L value). In this case when we are adding members or function args or return types, we only need to know how the type will be laid out and we can defer completing the pointee type until we later need it. The last type means we need a full definition for the clang type. Did some renaming of some enumerations to get rid of the old "DC" prefix (which stands for DebugCore which is no longer around). Modified the clang namespace support to be almost ready to be fed to the expression parser. I made a new ClangNamespaceDecl class that can carry around the AST and the namespace decl so we can copy it into the expression AST. I modified the symbol vendor and symbol file plug-ins to use this new class. llvm-svn: 118976

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

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 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.

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

Fixed the forward declaration issue that was present in the DWARF parser after adding methods to C++ and objective C classes. In order to make methods, we need the function prototype which means we need the arguments. Parsing these could cause a circular reference that caused an assertion. Added a new typedef for the clang opaque types which are just void pointers: lldb::clang_type_t. This appears in lldb-types.h. This was fixed by enabling struct, union, class, and enum types to only get a forward declaration when we make the clang opaque qual type for these types. When they need to actually be resolved, lldb_private::Type will call a new function in the SymbolFile protocol to resolve a clang type when it is not fully defined (clang::TagDecl::getDefinition() returns NULL). This allows us to be a lot more lazy when parsing clang types and keeps down the amount of data that gets parsed into the ASTContext for each module. Getting the clang type from a "lldb_private::Type" object now takes a boolean that indicates if a forward declaration is ok: clang_type_t lldb_private::Type::GetClangType (bool forward_decl_is_ok); So function prototypes that define parameters that are "const T&" can now just parse the forward declaration for type 'T' and we avoid circular references in the type system. llvm-svn: 115012

Fixed the forward declaration issue that was present in the DWARF parser after adding methods to C++ and objective C classes. In order to make methods, we need the function prototype which means we need the arguments. Parsing these could cause a circular reference that caused an assertion. Added a new typedef for the clang opaque types which are just void pointers: lldb::clang_type_t. This appears in lldb-types.h. This was fixed by enabling struct, union, class, and enum types to only get a forward declaration when we make the clang opaque qual type for these types. When they need to actually be resolved, lldb_private::Type will call a new function in the SymbolFile protocol to resolve a clang type when it is not fully defined (clang::TagDecl::getDefinition() returns NULL). This allows us to be a lot more lazy when parsing clang types and keeps down the amount of data that gets parsed into the ASTContext for each module. Getting the clang type from a "lldb_private::Type" object now takes a boolean that indicates if a forward declaration is ok: clang_type_t lldb_private::Type::GetClangType (bool forward_decl_is_ok); So function prototypes that define parameters that are "const T&" can now just parse the forward declaration for type 'T' and we avoid circular references in the type system. llvm-svn: 115012

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

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

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

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

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

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

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

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

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

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

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

Some descriptive text for the Python script feature: - help type summary add now gives some hints on how to use it frame variable and target variable now have a --no-summary-depth (-Y) option: - simply using -Y without an argument will skip one level of summaries, i.e. your aggregate types will expand their children and display no summary, even if they have one. children will behave normally - using -Y<int>, as in -Y4, -Y7, ..., will skip as many levels of summaries as given by the <int> parameter (obviously, -Y and -Y1 are the same thing). children beneath the given depth level will behave normally -Y0 is the same as omitting the --no-summary-depth parameter entirely This option replaces the defined-but-unimplemented --no-summary llvm-svn: 135336

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

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

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

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

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.

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.

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

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.

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

Added "target variable" command that allows introspection of global variables prior to running your binary. Zero filled sections now get section data correctly filled with zeroes when Target::ReadMemory reads from the object file section data. Added new option groups and option values for file lists. I still need to hook up all of the options to "target variable" to allow more complete introspection by file and shlib. Added the ability for ValueObjectVariable objects to be created with only the target as the execution context. This allows them to be read from the object files through Target::ReadMemory(...). Added a "virtual Module * GetModule()" function to the ValueObject class. By default it will look to the parent variable object and return its module. The module is needed when we have global variables that have file addresses (virtual addresses that are specific to module object files) and in turn allows global variables to be displayed prior to running. Removed all of the unused proxy object support that bit rotted in lldb_private::Value. Replaced a lot of places that used "FileSpec::Compare (lhs, rhs) == 0" code with the more efficient "FileSpec::Equal (lhs, rhs)". Improved logging in GDB remote plug-in. llvm-svn: 134579

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

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.

StreamString strm;
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

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

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

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.

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

This would cause many object files to stay around the life of LLDB, so after a recompile and rexecution, we would keep adding more and more memory.

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

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
