Greg Clayton 5d5028b54e Added the first of hopefully many python example scripts that show how to
use the python API that is exposed through SWIG to do some cool stuff.

Also fixed synchronous debugging so that all process control APIs exposed
through the python API will now wait for the process to stop if you set
the async mode to false (see disasm.py).

Sean Callanan 85a0a83a26 Added handling for external variables in function
arguments to the expression parser.  This means that
structs can be returned from the "expr" command.

Greg Clayton b71f384455 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.

Greg Clayton 0184f01936 Moved expression evaluation from CommandObjectExpression into
ClangUserExpression::Evaluate () as a public static function so anyone can
evaluate an expression.

Greg Clayton 1d3afba3a3 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").

Greg Clayton 0603aa9dc8 There are now to new "settings set" variables that live in each debugger
instance:

settings set frame-format <string>
settings set thread-format <string>

This allows users to control the information that is seen when dumping
threads and frames. The default values are set such that they do what they
used to do prior to changing over the the user defined formats.

This allows users with terminals that can display color to make different
items different colors using the escape control codes. A few alias examples
that will colorize your thread and frame prompts are:

settings set frame-format 'frame #${frame.index}: \033[0;33m${frame.pc}\033[0m{ \033[1;4;36m${module.file.basename}\033[0;36m ${function.name}{${function.pc-offset}}\033[0m}{ \033[0;35mat \033[1;35m${line.file.basename}:${line.number}}\033[0m\n'

settings set thread-format 'thread #${thread.index}: \033[1;33mtid\033[0;33m = ${thread.id}\033[0m{, \033[0;33m${frame.pc}\033[0m}{ \033[1;4;36m${module.file.basename}\033[0;36m ${function.name}{${function.pc-offset}}\033[0m}{, \033[1;35mstop reason\033[0;35m = ${thread.stop-reason}\033[0m}{, \033[1;36mname = \033[0;36m${thread.name}\033[0m}{, \033[1;32mqueue = \033[0;32m${thread.queue}}\033[0m\n'

A quick web search for "colorize terminal output" should allow you to see what
you can do to make your output look like you want it.

The "settings set" commands above can of course be added to your ~/.lldbinit
file for permanent use.

Changed the pure virtual 
    void ExecutionContextScope::Calculate (ExecutionContext&);
To:
    void ExecutionContextScope::CalculateExecutionContext (ExecutionContext&);
    
I did this because this is a class that anything in the execution context
heirarchy inherits from and "target->Calculate (exe_ctx)" didn't always tell
you what it was really trying to do unless you look at the parameter.

Caroline Tice deaab2220e Modify command options to use the new arguments mechanism. Now all command option
arguments are specified in a standardized way, will have a standardized name, and
have functioning help.

The next step is to start writing useful help for all the argument types.

llvm-svn: 115335
2010-10-01 19:59:14 +00:00
Caroline Tice e139cf2320 Add infrastructure for standardizing arguments for commands and
command options; makes it easier to ensure that the same type of
argument will have the same name everywhere, hooks up help for command
arguments, so that users can ask for help when they are confused about
what an argument should be; puts in the beginnings of the ability to
do tab-completion for certain types of arguments, allows automatic
syntax help generation for commands with arguments, and adds command
arguments into command options help correctly.

Currently only the breakpoint-id and breakpoint-id-range arguments, in
the breakpoint commands, have been hooked up to use the new mechanism.
The next steps will be to fix the command options arguments to use
this mechanism, and to fix the rest of the regular command arguments
to use this mechanism.  Most of the help text is currently missing or
dummy text; this will need to be filled in, and the existing argument
help text will need to be cleaned up a bit (it was thrown in quickly,
mostly for testing purposes).

Help command now works for all argument types, although the help may not
be very helpful yet.

Those commands that take "raw" command strings now indicate it in their
help text.

Greg Clayton 4957bf69e5 Cleaned up a unused member variable in Debugger.
Added the start of Host specific launch services, though it currently isn't
hookup up to anything. We want to be able to launch a process and use the
native launch services to launch an app like it would be launched by the
user double clicking on the app. We also eventually want to be able to run
a command line app in a newly spawned terminal to avoid terminal sharing.

Fixed an issue with the new DWARF forward type declaration stuff. A crasher
was found that was happening when trying to properly expand the forward
declarations.

llvm-svn: 115213
2010-09-30 21:49:03 +00:00
Sean Callanan 038df50315 Switched the expression parser from using TargetData
to using Clang to get type sizes.  This fixes a bug
where the type size for a double[2] was being wrongly
reported as 8 instead of 16 bytes, causing problems
for IRForTarget.

Also improved logging so that the next bug in this
area will be easier to find.

Jim Ingham 6c68fb4549 Add "-o" option to "expression" which prints the object description if available.
llvm-svn: 115115
2010-09-30 00:54:27 +00:00
Greg Clayton 1be10fca5f 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.

Greg Clayton 0fffff5816 Added the ability to create an objective C method for an objective C
interface in ClangASTContext. Also added two bool returning functions that
indicated if an opaque clang qual type is a CXX class type, and if it is an
ObjC class type.

Objective C classes now will get their methods added lazily as they are
encountered. The reason for this is currently, unlike C++, the 
DW_TAG_structure_type and owns the ivars, doesn't not also contain the
member functions. This means when we parse the objective C class interface
we either need to find all functions whose names start with "+[CLASS_NAME"
or "-[CLASS_NAME" and add them all to the class, or when we parse each objective
C function, we slowly add it to the class interface definition. Since objective
C's class doesn't change internal bits according to whether it has certain types
of member functions (like C++ does if it has virtual functions, or if it has
user ctors/dtors), I currently chose to lazily populate the class when each
functions is parsed. Another issue we run into with ObjC method declarations
is the "self" and "_cmd" implicit args are not marked as artificial in the
DWARF (DW_AT_artifical), so we currently have to look for the parameters by
name if we are trying to omit artificial function args if the language of the
compile unit is ObjC or ObjC++.

Sean Callanan fc55f5d1b0 Removed the hacky "#define this ___clang_this" handler
for C++ classes.  Replaced it with a less hacky approach:

 - If an expression is defined in the context of a
   method of class A, then that expression is wrapped as
   ___clang_class::___clang_expr(void*) { ... }
   instead of ___clang_expr(void*) { ... }.

 - ___clang_class is resolved as the type of the target
   of the "this" pointer in the method the expression
   is defined in.

 - When reporting the type of ___clang_class, a method
   with the signature ___clang_expr(void*) is added to
   that class, so that Clang doesn't complain about a
   method being defined without a corresponding
   declaration.

 - Whenever the expression gets called, "this" gets
   looked up, type-checked, and then passed in as the
   first argument.

This required the following changes:

 - The ABIs were changed to support passing of the "this"
   pointer as part of trivial calls.

 - ThreadPlanCallFunction and ClangFunction were changed
   to support passing of an optional "this" pointer.

 - ClangUserExpression was extended to perform the
   wrapping described above.

 - ClangASTSource was changed to revert the changes
   required by the hack.

 - ClangExpressionParser, IRForTarget, and
   ClangExpressionDeclMap were changed to handle
   different manglings of ___clang_expr flexibly.  This
   meant no longer searching for a function called
   ___clang_expr, but rather looking for a function whose
   name *contains* ___clang_expr.

 - ClangExpressionParser and ClangExpressionDeclMap now
   remember whether "this" is required, and know how to
   look it up as necessary.

A few inheritance bugs remain, and I'm trying to resolve
these.  But it is now possible to use "this" as well as
refer implicitly to member variables, when in the proper
context.

Greg Clayton 1b65488229 Added code that will allow completely customizable prompts for use in
replacing the "(lldb)" prompt, the "frame #1..." displays when doing
stack backtracing and the "thread #1....". This will allow you to see 
exactly the information that you want to see where you want to see it.
This currently isn't hookup up to the prompts yet, but it will be soon.

So what is the format of the prompts? Prompts can contain variables that
have access to the current program state. Variables are text that appears
in between a prefix of "${" and ends with a "}". Some of the interesting
variables include:

// The frame index (0, 1, 2, 3...)
${frame.index}

// common frame registers with generic names
${frame.pc}
${frame.sp}
${frame.fp}
${frame.ra}
${frame.flags}

// Access to any frame registers by name where REGNAME is any register name:
${frame.reg.REGNAME}

// The current compile unit file where the frame is located
${file.basename}
${file.fullpath}

// Function information
${function.name}
${function.pc-offset}

// Process info
${process.file.basename}
${process.file.fullpath}
${process.id}
${process.name}

// Thread info
${thread.id}
${thread.index}
${thread.name}
${thread.queue}
${thread.stop-reason}

// Target information
${target.arch}

// The current module for the current frame (the shared library or executable
// that contains the current frame PC value):
${module.file.basename}
${module.file.fullpath}

// Access to the line entry for where the current frame is when your thread
// is stopped:
${line.file.basename}
${line.file.fullpath}
${line.number}
${line.start-addr}
${line.end-addr}

Many times the information that you might have in your prompt might not be
available and you won't want it to print out if it isn't valid. To take care
of this you can enclose everything that must resolve into a scope. A scope
is starts with '{' and ends with '}'. For example in order to only display
the current file and line number when the information is available the format
would be:

"{ at {$line.file.basename}:${line.number}}"

Broken down this is:

start the scope: "{"

format whose content will only be displayed if all information is available:
        "at {$line.file.basename}:${line.number}"

end the scope: "}"

We currently can represent the infomration we see when stopped at a frame:

frame #0: 0x0000000100000e85 a.out`main + 4 at test.c:19

with the following format:

"frame #${frame.index}: ${frame.pc} {${module.file.basename}`}{${function.name}{${function.pc-offset}}{ at ${line.file.basename}:${line.number}}\n"

This breaks down to always print:

        "frame #${frame.index}: ${frame.pc} "

only print the module followed by a tick if we have a valid module:

        "{${module.file.basename}`}"
        
print the function name with optional offset:
        "{${function.name}{${function.pc-offset}}"

print the line info if it is available:
        
        "{ at ${line.file.basename}:${line.number}}"

then finish off with a newline:

        "\n"

Notice you can also put newlines ("\n") and tabs and everything else you
are used to putting in a format string when desensitized with the \ character.

Cleaned up some of the user settings controller subclasses. All of them 
do not have any global settings variables and were all implementing stubs
for the get/set global settings variable. Now there is a default version

Greg Clayton a701509229 Fixed the way set/show variables were being accessed to being natively
accessed by the objects that own the settings. The previous approach wasn't
very usable and made for a lot of unnecessary code just to access variables
that were already owned by the objects.

While I fixed those things, I saw that CommandObject objects should really
have a reference to their command interpreter so they can access the terminal
with if they want to output usaage. Fixed up all CommandObjects to take
an interpreter and cleaned up the API to not need the interpreter to be
passed in.

Fixed the disassemble command to output the usage if no options are passed
down and arguments are passed (all disassebmle variants take options, there
are no "args only").

Sean Callanan 44096b1a7e Added code to support use of "this" and "self" in

 - In ClangUserExpression::ClangUserExpression(),
   we now insert the following lines into the
   expression:
     #define this ___clang_this
     #define self ___clang_self

 - In ClangExpressionDeclMap::GetDecls(), we
   special-case ___clang_(this|self) and instead
   look up "this" or "self"

 - In ClangASTSource, we introduce the capability
   to generate Decls with a different, overridden,
   name from the one that was requested, e.g.
   this for ___clang_this.

2010-09-14 03:16:58 +00:00
Greg Clayton 016a95eb04 Looking at some of the test suite failures in DWARF in .o files with the
debug map showed that the location lists in the .o files needed some 
refactoring in order to work. The case that was failing was where a function
that was in the "__TEXT.__textcoal_nt" in the .o file, and in the 
"__TEXT.__text" section in the main executable. This made symbol lookup fail
due to the way we were finding a real address in the debug map which was
by finding the section that the function was in in the .o file and trying to
find this in the main executable. Now the section list supports finding a
linked address in a section or any child sections. After fixing this, we ran
into issue that were due to DWARF and how it represents locations lists. 
DWARF makes a list of address ranges and expressions that go along with those
address ranges. The location addresses are expressed in terms of a compile
unit address + offset. This works fine as long as nothing moves around. When
stuff moves around and offsets change between the remapped compile unit base
address and the new function address, then we can run into trouble. To deal
with this, we now store supply a location list slide amount to any location
list expressions that will allow us to make the location list addresses into
zero based offsets from the object that owns the location list (always a
function in our case). 

With these fixes we can now re-link random address ranges inside the debugger
for use with our DWARF + debug map, incremental linking, and more.

Another issue that arose when doing the DWARF in the .o files was that GCC
4.2 emits a ".debug_aranges" that only mentions functions that are externally
visible. This makes .debug_aranges useless to us and we now generate a real
address range lookup table in the DWARF parser at the same time as we index
the name tables (that are needed because .debug_pubnames is just as useless).
llvm-gcc doesn't generate a .debug_aranges section, though this could be 
fixed, we aren't going to rely upon it.

Renamed a bunch of "UINT_MAX" to "UINT32_MAX".

Sean Callanan 9e6ed53ea5 Bugfixes to the expression parser. Fixes include:
- If you put a semicolon at the end of an expression,
   this no longer causes the expression parser to
   error out.  This was a two-part fix: first,
   ClangExpressionDeclMap::Materialize now handles
   an empty struct (such as when there is no return
   value); second, ASTResultSynthesizer walks backward
   from the end of the ASTs until it reaches something
   that's not a NullStmt.

 - ClangExpressionVariable now properly byte-swaps when
   printing itself.

 - ClangUtilityFunction now cleans up after itself when
   it's done compiling itself.

 - Utility functions can now use external functions just
   like user expressions.

 - If you end your expression with a statement that does
   not return a value, the expression now runs correctly
   anyway.

Also, added the beginnings of an Objective-C object
validator function, which is neither installed nor used
as yet.

Greg Clayton 83ff3898f7 Fixed a crash that would happen when using "frame variables" on any struct,
union, or class that contained an enumeration type. When I was creating
the clang enumeration decl, I wasn't calling "EnumDecl::setIntegerType (QualType)" 
which means that if the enum decl was ever asked to figure out it's bit width
(getTypeInfo()) it would crash. We didn't run into this with enum types that 
weren't inside classes because the DWARF already told us how big the type was
and when we printed an enum we would never need to calculate the size, we
would use the pre-cached byte size we got from the DWARF. When the enum was 
in a struct/union/class and we tried to layout the struct, the layout code
would attempt to get the type info and segfault.

eSymbolTypeFunction: eSymbolTypeCode with IsDebug() == true
  eSymbolTypeGlobal: eSymbolTypeData with IsDebug() == true and IsExternal() == true
  eSymbolTypeStatic: eSymbolTypeData with IsDebug() == true and IsExternal() == false

This simplifies the logic when dealing with symbols and allows for symbols
to be coalesced into a single symbol most of the time.

Enabled the minimal symbol table for mach-o again after working out all the
kinks. We now get nice concise symbol tables and debugging with DWARF in the
.o files with a debug map in the binary works well again. There were issues
where the SymbolFileDWARFDebugMap symbol file parser was using symbol IDs and
symbol indexes interchangeably. Now that all those issues are resolved 
debugging is working nicely.

Johnny Chen 94de55d5c2 Added the capability to specify a one-liner Python script as the callback
command for a breakpoint, for example:

(lldb) breakpoint command add -p 1 "conditional_break.stop_if_called_from_a()"

The ScriptInterpreter interface has an extra method:

    /// Set a one-liner as the callback for the breakpoint command.
    virtual void 
    SetBreakpointCommandCallback (CommandInterpreter &interpreter,
                                  BreakpointOptions *bp_options,
                                  const char *oneliner);

to accomplish the above.

Also added a test case to demonstrate lldb's use of breakpoint callback command
to stop at function c() only when its immediate caller is function a().  The
following session shows the user entering the following commands:

1) command source .lldb (set up executable, breakpoint, and breakpoint command)
2) run (the callback mechanism will skip two breakpoints where c()'s immeidate caller is not a())
3) bt (to see that indeed c()'s immediate caller is a())
4) c (to continue and finish the program)

Jason Molenda fbcb7f2c4e The first part of an lldb native stack unwinder.
The Unwind and RegisterContext subclasses still need
to be finished; none of this code is used by lldb at
this point (unless you call into it by hand).

The ObjectFile class now has an UnwindTable object.

The UnwindTable object has a series of FuncUnwinders
objects (Function Unwinders) -- one for each function
in that ObjectFile we've backtraced through during this
debug session.

The FuncUnwinders object has a few different UnwindPlans.
UnwindPlans are a generic way of describing how to find
the canonical address of a given function's stack frame
(the CFA idea from DWARF/eh_frame) and how to restore the
caller frame's register values, if they have been saved
by this function.

UnwindPlans are created from different sources.  One source is the
eh_frame exception handling information generated by the compiler
for unwinding an exception throw.  Another source is an assembly
language inspection class (UnwindAssemblyProfiler, uses the Plugin
architecture) which looks at the instructions in the funciton
prologue and describes the stack movements/register saves that are
done.

Two additional types of UnwindPlans that are worth noting are
the "fast" stack UnwindPlan which is useful for making a first
pass over a thread's stack, determining how many stack frames there
are and retrieving the pc and CFA values for each frame (enough
to create StackFrameIDs).  Only a minimal set of registers is
recovered during a fast stack walk.  

The final UnwindPlan is an architectural default unwind plan.
These are provided by the ArchDefaultUnwindPlan class (which uses
the plugin architecture).  When no symbol/function address range can
be found for a given pc value -- when we have no eh_frame information
and when we don't have a start address so we can't examine the assembly
language instrucitons -- we have to make a best guess about how to 
unwind.  That's when we use the architectural default UnwindPlan.
On x86_64, this would be to assume that rbp is used as a stack pointer
and we can use that to find the caller's frame pointer and pc value.
It's a last-ditch best guess about how to unwind out of a frame.

There are heuristics about when to use one UnwindPlan versues the other --
this will all happen in the still-begin-written UnwindLLDB subclass of
Unwind which runs the UnwindPlans.

Greg Clayton 95897c6a3a Added more API to lldb::SBBlock to allow getting the block
parent, sibling and first child block, and access to the
inline function information.

Added an accessor the StackFrame:

	Block * lldb_private::StackFrame::GetFrameBlock();
	
LLDB represents inline functions as lexical blocks that have
inlined function information in them. The function above allows
us to easily get the top most lexical block that defines a stack
frame. When there are no inline functions in function, the block
returned ends up being the top most block for the function. When
the PC is in an inlined funciton for a frame, this will return the
first parent block that has inlined function information. The
other accessor: StackFrame::GetBlock() will return the deepest block
that matches the frame's PC value. Since most debuggers want to display
all variables in the current frame, the Block returned by
StackFrame::GetFrameBlock can be used to retrieve all variables for
the current frame.

Fixed the lldb_private::Block::DumpStopContext(...) to properly
display inline frames a block should display all of its inlined
functions. Prior to this fix, one of the call sites was being skipped.
This is a separate code path from the current default where inlined
functions get their own frames.

Fixed an issue where a block would always grab variables for any
child inline function blocks.

Caroline Tice 3df9a8dfd7 This is a very large commit that completely re-does the way lldb
handles user settable internal variables (the equivalent of set/show
variables in gdb).  In addition to the basic infrastructure (most of
which is defined in UserSettingsController.{h,cpp}, there are examples
of two classes that have been set up to contain user settable
variables (the Debugger and Process classes).  The 'settings' command
has been modified to be a command-subcommand structure, and the 'set',
'show' and 'append' commands have been moved into this sub-commabnd
structure.  The old StateVariable class has been completely replaced
by this, and the state variable dictionary has been removed from the
Command Interpreter.  Places that formerly accessed the state variable
mechanism have been modified to access the variables in this new
structure instead (checking the term-width; getting/checking the
prompt; etc.)

Variables are attached to classes; there are two basic "flavors" of
variables that can be set: "global" variables (static/class-wide), and
"instance" variables (one per instance of the class).  The whole thing
has been set up so that any global or instance variable can be set at
any time (e.g. on start up, in your .lldbinit file), whether or not
any instances actually exist (there's a whole pending and default
values mechanism to help deal with that).

Greg Clayton 2cad65a595 Fixed the StackFrame to correctly resolve the StackID's SymbolContextScope.
Added extra logging for stepping.

Fixed an issue where cached stack frame data could be lost between runs when
the thread plans read a stack frame.

llvm-svn: 112973
2010-09-03 17:10:42 +00:00
Greg Clayton 6dadd508e7 Added a new bool parameter to many of the DumpStopContext() methods that
might dump file paths that allows the dumping of full paths or just the
basenames. Switched the stack frame dumping code to use just the basenames for
the files instead of the full path.

Modified the StackID class to no rely on needing the start PC for the current
function/symbol since we can use the SymbolContextScope to uniquely identify
that, unless there is no symbol context scope. In that case we can rely upon
the current PC value. This saves the StackID from having to calculate the 
start PC when the StackFrame::GetStackID() accessor is called.

Also improved the StackID less than operator to correctly handle inlined stack
frames in the same stack.

Greg Clayton 288bdf9c1d 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.

Sean Callanan 8e999e4015 Added code to run pointer validation checks in

just now the crash will be in the function
___clang_valid_pointer_check().

2010-09-01 19:04:01 +00:00
Sean Callanan 6961e87847 Added support for dynamic sanity checking in
expressions.  Values used by the expression are
checked by validation functions which cause the
program to crash if the values are unsafe.

Major changes:

- Added IRDynamicChecks.[ch], which contains the
  core code related to this feature

- Modified CommandObjectExpression to install the
  validator functions into the target process.

- Added an accessor to Process that gets/sets the
  helper functions

Sean Callanan 823bb4cc24 Fixed a bug where the parser-specific members of
persistent variables were staying around too long.
This caused the following problem:

- A persistent result variable is created for the
  result of an expression.  The pointer to the
  corresponding Decl is stored in the variable.

- The persistent variable is looked up during
  struct generation (correctly) using its Decl.

- Another expression defines a new result variable
  which happens to have a Decl in the same place
  as the original result variable.

- The persistent variable is looked up during
  struct generation using its Decl, but the old
  result variable appears first in the list and
  has the same Decl pointer.

The fix is to destroy parser-specific data when
it is no longer valid.

Also improved some logging as I diagnosed the
bug.

2010-08-30 19:44:40 +00:00
Greg Clayton 59e8fc1c74 Clarified the intent of the SymbolContextScope class in the header
documentation. Symbol now inherits from the symbol
context scope so that the StackID can use a "SymbolContextScope *"
instead of a blockID (which could have been the same as some other
blockID from another symbol file). 

Modified the stacks that are created on subsequent stops to reuse
the previous stack frame objects which will allow for some internal
optimization using pointer comparisons during stepping. 

llvm-svn: 112495
2010-08-30 18:11:35 +00:00
Sean Callanan e71d553cd4 Added a ClangUtilityFunction class that allows the
debugger to insert self-contained functions for use by
expressions (mainly for error-checking).

In order to support detecting whether a crash occurred
in one of these helpers -- currently our preferred way
of reporting that an error-check failed -- added a bit
of support for getting the extent of a JITted function
in addition to just its base.

2010-08-27 22:35:26 +00:00
Greg Clayton 68275d5e56 Made it so we update the current frames from the previous frames by doing STL
swaps on the variable list, value object list, and disassembly. This avoids
us having to try and update frame indexes and other things that were getting
out of sync.

llvm-svn: 112301
2010-08-27 21:47:54 +00:00
Greg Clayton 5082c5fdf6 Simplified the StackFrameList class down to a single frames list again
instead of trying to maintain the real frame list (unwind frames) and an
inline frame list. The information is cheap to produce when we already have
looked up a block and was making stack frame uniquing difficult when trying
to use the previous stack when making the current stack.

We now maintain the previous value object lists for common frames between
a previous and current frames so we will be able to tell when variable values
change.

llvm-svn: 112277
2010-08-27 18:24:16 +00:00
Sean Callanan 1a8d40935d This is a major refactoring of the expression parser.
The goal is to separate the parser's data from the data
belonging to the parser's clients.  This allows clients
to use the parser to obtain (for example) a JIT compiled
function or some DWARF code, and then discard the parser
state.

Previously, parser state was held in ClangExpression and
used liberally by ClangFunction, which inherited from
ClangExpression.  The main effects of this refactoring 
are:

- reducing ClangExpression to an abstract class that
  declares methods that any client must expose to the
  expression parser,

- moving the code specific to implementing the "expr"
  command from ClangExpression and
  CommandObjectExpression into ClangUserExpression,
  a new class,

- moving the common parser interaction code from
  ClangExpression into ClangExpressionParser, a new
  class, and

- making ClangFunction rely only on
  ClangExpressionParser and not depend on the
  internal implementation of ClangExpression.

Side effects include:

- the compiler interaction code has been factored
  out of ClangFunction and is now in an AST pass
  (ASTStructExtractor),

- the header file for ClangFunction is now fully
  documented,

- several bugs that only popped up when Clang was
  deallocated (which never happened, since the
  lifetime of the compiler was essentially infinite)
  are now fixed, and

- the developer-only "call" command has been
  disabled.

I have tested the expr command and the Objective-C
step-into code, which use ClangUserExpression and
ClangFunction, respectively, and verified that they
work.  Please let me know if you encounter bugs or
poor documentation.

llvm-svn: 112249
2010-08-27 01:01:44 +00:00
Greg Clayton 12fc3e0f3e Changed the StackID to store its start PC address as a load address instead of
a section offset address.

Fixed up some very inefficient STL code.

llvm-svn: 112230
2010-08-26 22:05:43 +00:00
Jim Ingham 2976d00adb Change "Current" as in GetCurrentThread, GetCurrentStackFrame, etc, to "Selected" i.e. GetSelectedThread. Selected makes more sense, since these are set by some user action (a selection). I didn't change "CurrentProcess" since this is always controlled by the target, and a given target can only have one process, so it really can't be selected.
llvm-svn: 112221

Jim Ingham 6b8379c4e0 Add StackFrame::IsInlined.
llvm-svn: 112217
2010-08-26 20:44:45 +00:00
Greg Clayton 0445d8f498 Cleaned up the inline stack frame code one more time to prepare for inlined
code stepping. Also we now store the stack frames for the current and previous
stops in the thread in std::auto_ptr objects. When we create a thread stack
frame list we pass the previous frame into it so it can re-use the frames
and maintain will allow for variable changes to be detected. I will implement
the stack frame reuse next.

llvm-svn: 112152
2010-08-26 02:28:22 +00:00
Greg Clayton a45533defa The destructor for StackFrameList doesn't need to be virtual as we aren't

llvm-svn: 112010
2010-08-25 01:01:30 +00:00
Greg Clayton 158483cf62 Thread no longer needs to be a friend in StackFrameList now that StackFrameList
contains the entire stack backtrace.

llvm-svn: 112009
2010-08-25 00:58:59 +00:00
Greg Clayton 12daf946c8 Cleaned up the inline backtrace code even more by moving all stack backtracing
functionality into StackFrameList. This will allow us to copy the previous
stack backtrace from the previous stop into another variable so we can re-use
as much as possible from the previous stack backtrace.

llvm-svn: 112007
2010-08-25 00:35:26 +00:00
Greg Clayton 288e5afe6b Fixed another issue with the inline stack frames where if the first frame
has inlined functions that all started at the same address, then the inlined
backtrace would not produce correct stack frames.

Also cleaned up and inlined a lot of stuff in lldb_private::Address.

Added a function to StackFrame to detect if the frame is a concrete frame so
we can detect the difference between actual frames and inlined frames.

llvm-svn: 111989
2010-08-24 22:59:52 +00:00
Greg Clayton 9da7bd0739 Got a lot of the kinks worked out in the inline support after debugging more
complex inlined examples.

StackFrame classes don't have a "GetPC" anymore, they have "GetFrameCodeAddress()".
This is because inlined frames will have a PC value that is the same as the 
concrete frame that owns the inlined frame, yet the code locations for the
frame can be different. We also need to be able to get the real PC value for
a given frame so that variables evaluate correctly. To get the actual PC
value for a frame you can use:

    addr_t pc = frame->GetRegisterContext()->GetPC();

Some issues with the StackFrame stomping on its own symbol context were 
resolved which were causing the information to change for a frame when the
stack ID was calculated. Also the StackFrame will now correctly store the
symbol context resolve flags for any extra bits of information that were 
looked up (if you ask for a block only and you find one, you will alwasy have
the compile unit and function).

llvm-svn: 111964
2010-08-24 21:05:24 +00:00
Greg Clayton bba1ba8575 Clear the inline stack frame info when we clean all stack frames.
llvm-svn: 111891
2010-08-24 01:28:00 +00:00
Greg Clayton 1b72fcb7d1 Added support for inlined stack frames being represented as real stack frames
which is now on by default. Frames are gotten from the unwinder as concrete
frames, then if inline frames are to be shown, extra information to track
and reconstruct these frames is cached with each Thread and exanded as needed.

I added an inline height as part of the lldb_private::StackID class, the class
that helps us uniquely identify stack frames. This allows for two frames to
shared the same call frame address, yet differ only in inline height.

Fixed setting breakpoint by address to not require addresses to resolve.

A quick example:

% cat main.cpp

% ./build/Debug/lldb test/stl/a.out 
Current executable set to 'test/stl/a.out' (x86_64).

Each inline frame contains only the variables that they contain and each inlined
stack frame is treated as a single entity.

2010-08-23 23:09:38 +00:00
Greg Clayton 0b76a2c21f Modified the host process monitor callback function Host::StartMonitoringChildProcess
to spawn a thread for each process that is being monitored. Previously
LLDB would spawn a single thread that would wait for any child process which
isn't ok to do as a shared library (LLDB.framework on Mac OSX, or lldb.so on
linux). The old single thread used to call wait4() with a pid of -1 which 
could cause it to reap child processes that it shouldn't have.

Re-wrote the way Function blocks are handles. Previously I attempted to keep
all blocks in a single memory allocation (in a std::vector). This made the
code somewhat efficient, but hard to work with. I got rid of the old BlockList
class, and went to a straight parent with children relationship. This new 
approach will allow for partial parsing of the blocks within a function.

Sean Callanan d0ef0eff61 First step of refactoring variable handling in the

ClangExpressionVariable is now meant to be the

ClangPersistentVariable has been removed; we now

Jim Ingham 87c1191e0e Now that we are using the Unwinder (or Jason's new unwinder when that comes about) all the plugin-specific details of getting stack frames
should be hidden behind that, and the "GetStackFrameAtIndex" and "GetStackFrameCount" algorithms become generic.  So I moved them to Thread.cpp.

llvm-svn: 110899
2010-08-12 02:14:28 +00:00
Sean Callanan d1e5b439c9 Added automatically generated result variables for each
expression.  It is now possible to do things like this:

(lldb) expr int $i = 5; $i + 1
$0 = (int) 6
(lldb) expr $i + 3
$1 = (int) 8
(lldb) expr $1 + $0
$2 = (int) 14

As a bonus, this allowed us to move printing of
expression results into the ClangPersistentVariable
class.  This code needs a bit of refactoring -- in
particular, ClangExpressionDeclMap has eaten one too
many bacteria and needs to undergo mitosis -- but the
infrastructure appears to be holding up nicely.

llvm-svn: 110896
2010-08-12 01:56:52 +00:00
Sean Callanan 2235f32bbd Added support for persistent variables to the
expression parser.  It is now possible to type:

(lldb) expr int $i = 5; $i + 1
(int) 6
(lldb) expr $i + 2
(int) 7

The skeleton for automatic result variables is
also implemented.  The changes affect:

- the process, which now contains a 
  ClangPersistentVariables object that holds
  persistent variables associated with it
- the expression parser, which now uses
  the persistent variables during variable
  lookup
- TaggedASTType, where I loaded some commonly
  used tags into a header so that they are
  interchangeable between different clients of
  the class

site info.

it is currently created (by the Expression command)
is certainly wrong.

Greg Clayton f4b47e1579 Abtracted the old "lldb_private::Thread::StopInfo" into an abtract class.
This will allow debugger plug-ins to make any instance of "lldb_private::StopInfo"
that can completely describe any stop reason. It also provides a framework for
doing intelligent things with the stop info at important times in the lifetime
of the inferior. 

Examples include the signal stop info in StopInfoUnixSignal. It will check with
the process to see that the current action is for the signal. These actions
include wether to stop for the signal, wether the notify that the signal was
hit, and wether to pass the signal along to the inferior process. The 
StopInfoUnixSignal class overrides the "ShouldStop()" method of StopInfo and
this allows the stop info to determine if it should stop at the signal or 
continue the process. 


StopInfo subclasses must override the following functions:

    virtual lldb::StopReason
    GetStopReason () const = 0;

    virtual const char *
    GetDescription () = 0;


StopInfo subclasses can override the following functions:


    // If the subclass returns "false", the inferior will resume. The default
    // version of this function returns "true" which means the default stop
    // info will stop the process. The breakpoint subclass will check if
    // the breakpoint wants us to stop by calling any installed callback on
    // the breakpoint, and also checking if the breakpoint is for the current
    // thread. Signals will check if they should stop based off of the 
    // UnixSignal settings in the process.
    virtual bool
    ShouldStop (Event *event_ptr);

    // Sublasses can state if they want to notify the debugger when "ShouldStop"
    // returns false. This would be handy for breakpoints where you want to
    // log information and continue and is also used by the signal stop info
    // to notify that a signal was received (after it checks with the process
    // signal settings).
    virtual bool
    ShouldNotify (Event *event_ptr)
    {
        return false;
    }

    // Allow subclasses to do something intelligent right before we resume.
    // The signal class will figure out if the signal should be propagated
    // to the inferior process and pass that along to the debugger plug-ins.
    virtual void
    WillResume (lldb::StateType resume_state)
    {
        // By default, don't do anything
    }


The support the Mach exceptions was moved into the lldb/source/Plugins/Process/Utility
folder and now doesn't polute the lldb_private::Thread class with platform
specific code.

llvm-svn: 110184
2010-08-04 01:40:35 +00:00
Sean Callanan 5666b674f3 Added support for accessing members of C++ objects,
including superclass members.  This involved ensuring
that access control was ignored, and ensuring that
the operands of BitCasts were properly scanned for
variables that needed importing.

Also laid the groundwork for declaring objects of
custom types; however, this functionality is disabled
for now because of a potential loop in ASTImporter.

llvm-svn: 110174
2010-08-04 01:02:13 +00:00
Greg Clayton 3504eee8a8 Added FindTypes to Module and ModuleList.
llvm-svn: 110093
2010-08-03 01:26:16 +00:00
Greg Clayton b0b9fe610a Added support for objective C built-in types: id, Class, and SEL. This
involved watching for the objective C built-in types in DWARF and making sure
when we convert the DWARF types into clang types that we use the appropriate
ASTContext types.

Added a way to find and dump types in lldb (something equivalent to gdb's 
"ptype" command):

    image lookup --type <TYPENAME>

This only works for looking up types by name and won't work with variables.
It also currently dumps out verbose internal information. I will modify it
to dump more appropriate user level info in my next submission.

Hookup up the "FindTypes()" functions in the SymbolFile and SymbolVendor so
we can lookup types by name in one or more images.

Fixed "image lookup --address <ADDRESS>" to be able to correctly show all
symbol context information, but it will only show this extra information when
the new "--verbose" flag is used.

Updated to latest LLVM to get a few needed fixes.

llvm-svn: 110089
2010-08-03 00:35:52 +00:00
Sean Callanan 5300d37aa7 Added support for rewriting objc_msgSend so we can
call Objective-C methods from expressions.  Also added
some more logging to the function-calling thread plan
so that we can see the registers when a function
finishes.

Also documented things maybe a bit better.

llvm-svn: 109938
2010-07-31 01:32:05 +00:00
Johnny Chen 7dc2e4784e We can do better when reporting the status of one-liner script execution.
Change the prototype of ScriptInterpreter::ExecuteOneLine() to return bool
instead of void and take one additional parameter as CommandReturnObject *.

Propagate the status of one-liner execution back appropriately.

llvm-svn: 109899
2010-07-30 22:33:14 +00:00
Greg Clayton 48e4254989 Added "void Clear();" methods to SBDebugger, SBTarget and SBThread so they can release their shared pointers.
llvm-svn: 109882
2010-07-30 20:12:55 +00:00
Greg Clayton 9e40956aea Created lldb::LanguageType by moving an enumeration from the
lldb_private::Language class into the enumerations header so it can be freely
used by other interfaces.

Added correct objective C class support to the DWARF symbol parser. Prior to
this fix we were parsing objective C classes as C++ classes and now that the
expression parser is ready to call functions we need to make sure the objective
C classes have correct AST types.

llvm-svn: 109574
2010-07-28 02:04:09 +00:00
Sean Callanan cc54bd3cef Added and improved logging. This is helping us as we
diagnose a problem where we're not correctly emitting
PIC code.

llvm-svn: 109568
2010-07-28 01:00:59 +00:00
Sean Callanan 7ea3501bd8 Added support for calling functions from expressions.
Right now we mock up the function as a variadic
function when generating the IR for the call; we need
to eventually make the function be the right type if
the type is available.

llvm-svn: 109543
2010-07-27 21:39:39 +00:00
Sean Callanan 4edba2d130 Added support for locating a function that is
referenced in the IR.  We don't yet support updating
the call to that function.

llvm-svn: 109483
2010-07-27 02:07:53 +00:00
Sean Callanan 8ade104a0a Changed SymbolContext so when you search for functions
it returns a list of functions as a SymbolContextList.

Rewrote the clients of SymbolContext to use this
SymbolContextList.

Rewrote some of the providers of the data to SymbolContext
to make them respect preferences as to whether the list
should be cleared first; propagated that change out.

ClangExpressionDeclMap and ClangASTSource use this new
function list to properly generate function definitions -
even for functions that don't have a prototype in the
debug information.

llvm-svn: 109476
2010-07-27 00:55:47 +00:00
Sean Callanan ddb46efcca Updated the IR converter for the target to eliminate
spurious guard variables on expression statics.

Updated the AST result synthesizer to eliminate the
unneeded result pointer.

Very rudimentary expressions now evaluate correctly
in the target using the new JIT-based mechanism.

llvm-svn: 109317
2010-07-24 01:37:44 +00:00
Greg Clayton 9fed0d85b2 Added needed breakpoint functionality to the public API that includes:
SBTarget:
    - get breakpoint count
    - get breakpoint at index
  SBBreakpoint:
    - Extract data from breakpoint events

llvm-svn: 109289
2010-07-23 23:33:17 +00:00
Sean Callanan 289e07b9d0 Added logging:
- When we JIT an expression, we print the disassembly
  of the generated code
- When we put the structure into the target, we print
  the individual entries in the structure byte for
  byte.

llvm-svn: 109254
2010-07-23 18:59:12 +00:00
Greg Clayton aaa58c6679 Added a new utility class that I have wanted for a while. The CleanUp
class is a templatized class that allows you to have a cleanup function called
on a data value of type T when the value is set or when the object goes
out of scope. It has support for very rudimentary invalid value detection that
can be enabled by using the appropriate constructor. 

Anyone with template experience that can see ways of improving this class
please let me know. The example code shows a few typical scenarios in which
I would like to use it. It is currently coded with simple type T values
in mind (integer file descriptors, pointers, etc), but I am sure some 
specialization might help out the class for more complex types.

There is a lot of documentation including examples in the CleanUp.h header 
file. 

llvm-svn: 109239
2010-07-23 17:42:15 +00:00
Greg Clayton 896dff661a Centralized the Mach exception stop info code by adding it as a first

llvm-svn: 109226
2010-07-23 15:37:46 +00:00
Sean Callanan 6dde30e964 Added extensive logging of the code that is actually going
to be executed by the inferior.  This required explicit support
from RecordingMemoryManager for finding the address range
belonging to a particular function.

Also fixed a bug in DisassemblerLLVM where the disassembler
assumed there was an AddressRange available even when it was
NULL.

llvm-svn: 109209
2010-07-23 02:19:15 +00:00
Sean Callanan ebf7707e53 Modified TaggedASTType to inherit from ClangASTType
and moved it to its own header file for cleanliness.

Added more logging to ClangFunction so that we can
diagnose crashes in the executing expression.

Added code to extract the result of the expression
from the struct that is passed to the JIT-compiled
code.

llvm-svn: 109199
2010-07-23 00:16:21 +00:00
Greg Clayton 8cf0593c87 Added a new enumeration named "ClangASTContext::AccessType" that abstracts the type creation from the various access enumerations in Clang. Currently there are clang::AccessSpecifier and the objective C ivars have their own enumeration. So I added a new enumeration that will allow a consistent interface when creating types through ClangASTContext.
I also added new functions to create an Objective C class, ivar and set an objective C superclass. They aren't hooked up in the DWARF parser yet. That is the next step, though I am unsure if I will do this in the DWARF parser or try and do it generically in the existing Record manipulation functions.

llvm-svn: 109130
2010-07-22 18:30:50 +00:00
Greg Clayton 4ceb9980c8 Modified both the ObjectFileMachO and ObjectFileELF to correctly set the
SectionType for Section objects for DWARF.

Modified the DWARF plug-in to get the DWARF sections by SectionType so we
can safely abstract the LLDB core from section names for the various object
file formats.

Modified the SectionType definitions for .debug_pubnames and .debug_pubtypes
to use the correct case.

llvm-svn: 109054
2010-07-21 22:54:26 +00:00
Greg Clayton e1a916a74d 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.

Also did some cleanup on the ASTType by renaming it to ClangASTType and
renaming the header file. Moved a lot of "AST * + opaque clang type *"
functionality from lldb_private::Type over into ClangASTType.

llvm-svn: 109046
2010-07-21 22:12:05 +00:00
Greg Clayton 8c920840a4 Add new SectionType enumerations for all DWARF sections. ObjectFile parsers should start properly setting the section types for DWARF sections, then we can move the DWARF SymbolFile parser over to finding the sections by the appropriate SectionType.
llvm-svn: 109041
2010-07-21 21:51:36 +00:00
Greg Clayton 70e33eb06e Allow searching for a section by SectionType.

llvm-svn: 108970
2010-07-20 23:53:01 +00:00
Sean Callanan 1d18066411 Added functionality to dematerialize values that were
used by the JIT compiled expression, including the
result of the expression.

Also added a new class, ASTType, which encapsulates an
opaque Clang type and its associated AST context.

Refactored ClangExpressionDeclMap to use ASTTypes,
significantly reducing the possibility of mixups of
types from different AST contexts.

llvm-svn: 108965

Greg Clayton 471b31ce62 Remove use of STL collection class use of the "data()" method since it isn't

Stephen Wilson 50bd94f961 Have Process::CreateBreakpointSite return a break_id_t instead of a user_id_t.
Also, update BreakpointLocation::ResolveBreakpointSite to check for invalid

2010-07-14 00:18:15 +00:00
Sean Callanan 549c9f7f9a "expr -i" now performs the required transforms to
prepare the IR for JIT compilation.  We still need
to do the JIT compilation and move the arguments

llvm-svn: 108279
2010-07-13 21:41:46 +00:00
Jim Ingham a56c800607 Add an "Avoid Frames matching this regular expression" to ThreadPlanStepInRange.
This relies on ThreadPlanStepOut working correctly, which it doesn't currently for Inlined functions, so this feature is only partially useful until we take care of Stepping Out of inlined functions.
Added an option to "thread step-in" to set the avoid regular expression.  This is mostly for testing, once the Setting code is redone, we'll move this to a general setting.

llvm-svn: 108036
2010-07-10 02:27:39 +00:00
Greg Clayton c982c768d2 Merged Eli Friedman's linux build changes where he added Makefile files that

Jim Ingham ebc09c36e9 Fix GetRepeatCommand so it works with multi-word commands.
Move the "source", "alias", and "unalias" commands to "commands *".
Move "source-file" to "source list".
Added a "source info" command but it isn't implemented yet.

llvm-svn: 107751
2010-07-07 03:36:20 +00:00
Jim Ingham 1308bb2791 Added a "GetRepeatCommand" to the command object. The Interpreter uses this
instead of the last history item to provide a command for the "empty" command.
Use this in the source-file command to make <RETURN> continue the listing rather
than relist the first listing...

llvm-svn: 107736
2010-07-06 23:48:33 +00:00
Jim Ingham 279a6c2669 Hide the logic for command resolution for commands, aliases & user commands behind a single
interface so everybody does it the same way.  Add an "exact" lookup for internal uses.

Fix up a few little cases where we weren't reporting command lookup errors correctly.

Added "b" as an alias for "breakpoint" so it doesn't collide with "bt".

llvm-svn: 107718

Sean Callanan 2ab712f212 Added the skeleton of an IR transformer that will
prepare IR for execution in the target.  Wired the
expression command to use this IR transformer when
conversion to DWARF fails, and wired conversion to
DWARF to always fail (well, we don't generate any
DWARF...)

llvm-svn: 107559
2010-07-03 01:35:46 +00:00
Sean Callanan 2df8a1f39c Added the skeleton of a transformation pass to
convert IR to DWARF.  So far, this pass only
performs a depth-first traversal of the IR,
logging each basic block as it finds it.

Greg Clayton 54b8b8c1a7 Fixed up disassembly to not emit the module name before all function names
that are in the disassembly comments since most of them are in the same
module (shared library). 

Fixed a crasher that could happen when disassembling special section data.

Added an address dump style that shows the symbol context without the module
(used in the disassembly code).

llvm-svn: 107366
2010-07-01 01:26:43 +00:00
Greg Clayton dda4f7b520 Centralized all disassembly into static functions in source/Core/Disassembler.cpp.
Added the ability to read memory from the target's object files when we aren't
running, so disassembling works before you run!

Cleaned up the API to lldb_private::Target::ReadMemory().

Cleaned up the API to the Disassembler to use actual "lldb_private::Address"
objects instead of just an "addr_t". This is nice because the Address objects
when resolved carry along their section and module which can get us the 
object file. This allows Target::ReadMemory to be used when we are not 
running.

Added a new lldb_private::Address dump style: DumpStyleDetailedSymbolContext
This will show a full breakdown of what an address points to. To see some
sample output, execute a "image lookup --address <addr>".

Fixed SymbolContext::DumpStopContext(...) to not require a live process in
order to be able to print function and symbol offsets.

llvm-svn: 107350
2010-06-30 23:03:03 +00:00
Caroline Tice ebc1bb277c Add a unique ID to each debugger instance.
Add functions to look up debugger by id
Add global variable to lldb python module, to hold debugger id
Modify embedded Python interpreter to update the global variable with the
 id of its current debugger.
Modify the char ** typemap definition in lldb.swig to accept 'None' (for NULL)
 as a valid value.

The point of all this is so that, when you drop into the embedded interpreter
from the command interpreter (or when doing Python-based breakpoint commands),
there is a way for the Python side to find/get the correct debugger
instance ( by checking debugger_unique_id, then calling 
SBDebugger::FindDebuggerWithID  on it).

llvm-svn: 107287
2010-06-30 16:22:25 +00:00
Jim Ingham 558ce124eb Add a source file completer to the CommandCompleters.
Add a way for the completers to say whether the completed argument should have a space inserted after is
or not.
Added the file name completer to the "file" command.

llvm-svn: 107247
2010-06-30 05:02:46 +00:00
Greg Clayton 8d38ac4536 Fixed debug map in executable + DWARF in .o debugging on Mac OS X.
Added the ability to dump any file in the global module cache using any of
the "image dump" commands. This allows us to dump the .o files that are used
with DWARF + .o since they don't belong the the target list for the current
target.

llvm-svn: 107100
2010-06-28 23:51:11 +00:00
Greg Clayton 0c5cd90d63 Added function name types to allow us to set breakpoints by name more
intelligently. The four name types we currently have are:

eFunctionNameTypeFull       = (1 << 1), // The function name.
                                        // For C this is the same as just the name of the function
                                        // For C++ this is the demangled version of the mangled name.
                                        // For ObjC this is the full function signature with the + or
                                        // - and the square brackets and the class and selector
eFunctionNameTypeBase       = (1 << 2), // The function name only, no namespaces or arguments and no class 
                                        // methods or selectors will be searched.
eFunctionNameTypeMethod     = (1 << 3), // Find function by method name (C++) with no namespace or arguments
eFunctionNameTypeSelector   = (1 << 4)  // Find function by selector name (ObjC) names


this allows much more flexibility when setting breakoints:

(lldb) breakpoint set --name main --basename
(lldb) breakpoint set --name main --fullname
(lldb) breakpoint set --name main --method
(lldb) breakpoint set --name main --selector

The default:

(lldb) breakpoint set --name main

will inspect the name "main" and look for any parens, or if the name starts
with "-[" or "+[" and if any are found then a full name search will happen.
Else a basename search will be the default.

Fixed some command option structures so not all options are required when they
shouldn't be.

Cleaned up the breakpoint output summary.

Made the "image lookup --address <addr>" output much more verbose so it shows
all the important symbol context results. Added a GetDescription method to 
many of the SymbolContext objects for the more verbose output.

Greg Clayton 6611103cfe Very large changes that were needed in order to allow multiple connections
to the debugger from GUI windows. Previously there was one global debugger
instance that could be accessed that had its own command interpreter and
current state (current target/process/thread/frame). When a GUI debugger
was attached, if it opened more than one window that each had a console
window, there were issues where the last one to setup the global debugger
object won and got control of the debugger.

To avoid this we now create instances of the lldb_private::Debugger that each 
has its own state:
- target list for targets the debugger instance owns
- current process/thread/frame
- its own command interpreter
- its own input, output and error file handles to avoid conflicts
- its own input reader stack

So now clients should call:

    SBDebugger::Initialize(); // (static function)

    SBDebugger debugger (SBDebugger::Create());
    // Use which ever file handles you wish
    debugger.SetErrorFileHandle (stderr, false);
    debugger.SetOutputFileHandle (stdout, false);
    debugger.SetInputFileHandle (stdin, true);

    // main loop
    
    SBDebugger::Terminate(); // (static function)
    
SBDebugger::Initialize() and SBDebugger::Terminate() are ref counted to
ensure nothing gets destroyed too early when multiple clients might be
attached.

Cleaned up the command interpreter and the CommandObject and all subclasses
to take more appropriate arguments.

Jim Ingham b01e742af7 Two changes in this checkin. Added a ThreadPlanKind so that I can do some reasoning based on the kind of thread plan
without having to use RTTI.
Removed the ThreadPlanContinue and replaced with a ShouldAutoContinue query that serves the same purpose.  Having to push
another plan to assert that if there's no other indication the target should continue when this plan is popped was flakey
and error prone.  This method is more stable, and fixed problems we were having with thread specific breakpoints.

Jim Ingham 0136309f5a Change the Breakpoint & BreakpointLocation GetDescription methods so they call the BreakpointOptions::GetDescription rather
than picking bits out of the breakpoint options.  Added BreakpointOptions::GetDescription to do this job.  Some more mucking
around to keep the breakpoint listing from getting too verbose.

Push this through all the breakpoint management code.  Allow this to be set when the breakpoint is created.
Fix the Process classes so that a breakpoint hit that is not for a particular thread is not reported as a 
breakpoint hit event for that thread.
Added a "breakpoint configure" command to allow you to reset any of the thread 
specific options (or the ignore count.)

We need to put this in LLDB since we need to vend this in our API
because our public API uses shared pointers to our private objects.

Added the new SharingPtr.cpp/.h files into source/Utility.

Added a shell script build phase that fixes up all headers in the

ickiness, and is cleaner to boot.

would be great if someone in the know could check behind me.

Greg Clayton 41f923275e Made lldb_private::ArchSpec more generic so that it can take a mach-o cpu
type and sub-type, or an ELF e_machine value. Also added a generic CPU type
to the arch spec class so we can have a single arch definition that the LLDB
core code can use. Previously a lot of places in the code were using the
mach-o definitions from a macosx header file. 

Switches over to using "llvm/Support/MachO.h" for the llvm::MachO::XXX for the
CPU types and sub types for mach-o ArchSpecs. Added "llvm/Support/ELF.h" so 
we can use the "llvm::ELF::XXX" defines for the ELF ArchSpecs.

Got rid of all CPU_TYPE_ and CPU_SUBTYPE_ defines that were previously being
used in LLDB.
