Greg Clayton 0f28986a54 Patch from Enrico Granata that moves SBData related functions into the SBData
class instead of requiring a live process in order to be able to create useful
SBData objects.

Jim Ingham 73ca05a2a0 Add the ability to capture the return value in a thread's stop info, and print it
as part of the thread format output.
Currently this is only done for the ThreadPlanStepOut.
Add a convenience API ABI::GetReturnValueObject.
Change the ValueObject::EvaluationPoint to BE an ExecutionContextScope, rather than
trying to hand out one of its subsidiary object's pointers.  That way this will always
be good.

Greg Clayton f9322415dc <rdar://problem/10584789>
Added a static memory pressure function in SBDebugger:

    void SBDebugger::MemoryPressureDetected ()

This can be called by applications that detect memory pressure to cause LLDB to release cached information.

Greg Clayton e91b7957b2 Expose new read memory fucntion through python in SBProcess:
size_t
    SBProcess::ReadCStringFromMemory (addr_t addr, void *buf, size_t size, lldb::SBError &error);

    uint64_t
    SBProcess::ReadUnsignedFromMemory (addr_t addr, uint32_t byte_size, lldb::SBError &error);

    lldb::addr_t
    SBProcess::ReadPointerFromMemory (addr_t addr, lldb::SBError &error);

These ReadCStringFromMemory() has some SWIG type magic that makes it return the
python string directly and the "buf" is not needed:

error = SBError()
max_cstr_len = 256
cstr = lldb.process.ReadCStringFromMemory (0x1000, max_cstr_len, error)
if error.Success():
    ....

The other two functions behave as expteced. This will make it easier to get integer values
from the inferior process that are correctly byte swapped. Also for pointers, the correct
pointer byte size will be used.

Also cleaned up a few printf style warnings for the 32 bit lldb build on darwin.

Sean Callanan 50952e9571 I have added a function to SBTarget that allows
clients to disassemble a series of raw bytes as
demonstrated by a new testcase.

In the future, this API will also allow clients
to provide a callback that adds comments for
addresses in the disassembly.

I also modified the SWIG harness to ensure that
Python ByteArrays work as well as strings as
sources of raw data.

Johnny Chen a2b514a3f2 Add more robustness - use PyString_CheckExact(pvalue) to check whether pvalue is a Python string before
calling PyString_AsString(pvalue).  Similar to http://llvm.org/viewvc/llvm-project?rev=146584&view=rev.

LLDBSwigPythonCallCommand crashes when a command script returns an object 

Add more robustness to LLDBSwigPythonCallCommand.  It should check whether the returned Python object
is a string, and only assign it as the error msg when the check holds.
Also add a regression test.

Johnny Chen 49cb85db64 SBProcess.PutSTDIN() needs to be properly typemapped when swigging,
so that we can do Python scripting like this:

        target = self.dbg.CreateTarget(self.exe)

        self.dbg.SetAsync(True)
        process = target.LaunchSimple(None, None, os.getcwd())

        process.PutSTDIN("Line 1 Entered.\n")
        process.PutSTDIN("Line 2 Entered.\n")
        process.PutSTDIN("Line 3 Entered.\n")

Add TestProcessIO.py to exercise the process IO API: PutSTDIN()/GetSTDOUT()/GetSTDERR().

Greg Clayton da7bc7d000 <rdar://problem/10126482>
Fixed an issues with the SBType and SBTypeMember classes:
- Fixed SBType to be able to dump itself from python
- Fixed SBType::GetNumberOfFields() to return the correct value for objective C interfaces
- Fixed SBTypeMember to be able to dump itself from python
- Fixed the SBTypeMember ability to get a field offset in bytes (the value
  being returned was wrong)
- Added the SBTypeMember ability to get a field offset in bits


Cleaned up a lot of the Stream usage in the SB API files.

Greg Clayton dce502ede0 Fixed the Xcode project building of LLVM to be a bit more user friendly:
- If you download and build the sources in the Xcode project, x86_64 builds
  by default using the "llvm.zip" checkpointed LLVM.
- If you delete the "lldb/llvm.zip" and the "lldb/llvm" folder, and build the
  Xcode project will download the right LLVM sources and build them from 
  scratch
- If you have a "lldb/llvm" folder already that contains a "lldb/llvm/lib"
  directory, we will use the sources you have placed in the LLDB directory.
  
Python can now be disabled for platforms that don't support it. 

Changed the way the libllvmclang.a files get used. They now all get built into
arch specific directories and never get merged into universal binaries as this
was causing issues where you would have to go and delete the file if you wanted
to build an extra architecture slice.

Enrico Granata a9dbf4325e this patch introduces a new command script import command which takes as input a filename for a Python script and imports the module contained in that file. the containing directory is added to the Python path such that dependencies are honored. also, the module may contain an __lldb_init_module(debugger,dict) function, which gets called after importing, and which can somehow initialize the module's interaction with lldb
llvm-svn: 142283
2011-10-17 21:45:27 +00:00
Johnny Chen 16dcf718d3 Add a commnad to set a condition for a watchpoint. Example:
watchpoint modify -c 'global==5'

modifies the last created watchpoint so that the condition expression
is evaluated at the stop point to decide whether we should proceed with
the stopping.

Also add SBWatchpont::SetCondition(const char *condition) to set condition
programmatically.

Test cases to come later.

2011-10-14 19:15:48 +00:00
Johnny Chen 01a678603a SBValue::Watch() and SBValue::WatchPointee() are now the official API for creating
a watchpoint for either the variable encapsulated by SBValue (Watch) or the pointee
encapsulated by SBValue (WatchPointee).

Removed SBFrame::WatchValue() and SBFrame::WatchLocation() API as a result of that.

Modified the watchpoint related test suite to reflect the change.

Plus replacing WatchpointLocation with Watchpoint throughout the code base.

There are still cleanups to be dome.  This patch passes the whole test suite.
Check it in so that we aggressively catch regressions.

Greg Clayton 1ed54f50c5 Cleaned up the the code that figures out the inlined stack frames given a
symbol context that represents an inlined function. This function has been
renamed internally to:

bool
SymbolContext::GetParentOfInlinedScope (const Address &curr_frame_pc, 
                                        SymbolContext &next_frame_sc, 
                                        Address &next_frame_pc) const;
                                        
And externally to:

SBSymbolContext
SBSymbolContext::GetParentOfInlinedScope (const SBAddress &curr_frame_pc, 
                                          SBAddress &parent_frame_addr) const;

The correct blocks are now correctly calculated.

Switched the stack backtracing engine (in StackFrameList) and the address
context printing over to using the internal SymbolContext::GetParentOfInlinedScope(...) 
so all inlined callstacks will match exactly.

llvm-svn: 140833
2011-09-30 00:49:02 +00:00
Johnny Chen c44e20cec0 Migrate the in_range(symbol, section) and symbol_iter(module, section) utility functions
from lldbutil.py to the lldb.py proper.  The in_range() function becomes a function in
the lldb module.  And the symbol_iter() function becomes a method within the SBModule
called symbol_in_section_iter().  Example:

        # Iterates the text section and prints each symbols within each sub-section.
        for subsec in text_sec:
            print INDENT + repr(subsec)
            for sym in exe_module.symbol_in_section_iter(subsec):
                print INDENT2 + repr(sym)
                print INDENT2 + 'symbol type: %s' % symbol_type_to_str(sym.GetType())

might produce this following output:

Johnny Chen d4dd7993b5 Export the watchpoint related API (SBWatchpointLocation class and added SBTarget methods)
to the Python interface.

Implement yet another (threre're 3 now) iterator protocol for SBTarget: watchpoint_location_iter(),
to iterate on the available watchpoint locations.  And add a print representation for
SBWatchpointLocation.

Fixed the symbolicate example script and the internals.

llvm-svn: 140591
2011-09-27 00:58:45 +00:00
Greg Clayton 8f7180b11e Added more functionality to the public API to allow for better
symbolication. Also improved the SBInstruction API to allow
access to the instruction opcode name, mnemonics, comment and
instruction data.

Added the ability to edit SBLineEntry objects (change the file,
line and column), and also allow SBSymbolContext objects to be
modified (set module, comp unit, function, block, line entry
or symbol). 

The SymbolContext and SBSymbolContext can now generate inlined
call stack infomration for symbolication much easier using the
SymbolContext::GetParentInlinedFrameInfo(...) and 
SBSymbolContext::GetParentInlinedFrameInfo(...) methods.

llvm-svn: 140518
2011-09-26 07:11:27 +00:00
Greg Clayton d9dc52dc4c Added the ability to get all section contents, or the section
contents starting at an offset (2 separate methods). This helps
the scripting interface stay more natural by allowing both from
Python.

Added the ability to dump data with address annotations when
call SBData::GetDescription().

Hooked up the SBSection to the __repr__ so you can print section
objects from within python.

Improved the dumping of symbols from python.

Fixed the .i interface references which were set to "Relative to this Group"
which somehow included Jim's "lldb-clean" root directory in the path. The
interfaces are now in a folder called "interfaces" withing the Xcode API
subfolder.

llvm-svn: 140442
2011-09-24 01:32:22 +00:00
Greg Clayton cac9c5f971 Added to the public API to allow symbolication:
- New SBSection objects that are object file sections which can be accessed
  through the SBModule classes. You can get the number of sections, get a 
  section at index, and find a section by name.
- SBSections can contain subsections (first find "__TEXT" on darwin, then
  us the resulting SBSection to find "__text" sub section).
- Set load addresses for a SBSection in the SBTarget interface
- Set the load addresses of all SBSection in a SBModule in the SBTarget interface
- Add a new module the an existing target in the SBTarget interface
- Get a SBSection from a SBAddress object

This should get us a lot closer to being able to symbolicate using LLDB through
the public API.

llvm-svn: 140437
2011-09-24 00:52:29 +00:00
Johnny Chen 6027c94d2f Add an SB API SBFrame::WatchValue() and exported to the Python interface to
set a watchpoint Pythonically.  If the find-and-watch-a-variable operation
fails, an invalid SBValue is returned, instead.

Example Python usage:

        value = frame0.WatchValue('global',
                                  lldb.eValueTypeVariableGlobal,
                                  lldb.LLDB_WATCH_TYPE_READ|lldb.LLDB_WATCH_TYPE_WRITE)

Add TestSetWatchpoint.py to exercise this API.
We have 400 test cases now.

Greg Clayton bf2331c491 Added the ability to introspect types thourgh the public SBType interface.
Fixed up many API calls to not be "const" as const doesn't mean anything to
most of our lldb::SB objects since they contain a shared pointer, auto_ptr, or
pointer to the types which circumvent the constness anyway.
