- Clang now completes all Objective-C objects (if
  they are not already complete, and they have
  external lexical sources) during structure
  layout, avoiding a LLDB crash.

- The Clang Decl printer handles reference types
  correctly.  This prevents LLDB from crashing
  when expression logging is enabled.

 std::string has a summary provider
 std::vector std::list and std::map have both a summary and a synthetic children provider
Given the usage of a custom namespace (std::__1::classname) for the implementation of libc++, we keep both libstdcpp and libc++ formatters enabled at the same time since that raises no conflicts and enabled for seamless transition between the two
The formatters for libc++ reside in a libcxx category, and are loaded from libcxx.py (to be found in examples/synthetic)

The formatters-stl test cases have been divided to be separate for libcxx and libstdcpp. This separation is necessary because
 (a) we need different compiler flags for libc++ than for libstdcpp
 (b) libc++ inlines a lot more than libstdcpp and some code changes were required to accommodate this difference

llvm-svn: 152570

This takes two important changes:

- Calling blocks is now supported.  You need to
  cast their return values, but that works fine.

- We now can correctly run JIT-compiled
  expressions that use floating-point numbers.

Also, we have taken a fix that allows us to
ignore access control in Objective-C as in C++.

llvm-svn: 152286

This was done in SBTarget:

lldb::SBInstructionList
lldb::SBTarget::ReadInstructions (lldb::SBAddress base_addr, uint32_t count);

Also cleaned up a few files in the LLDB.framework settings.

llvm-svn: 152152

Add a command and an SB API to create exception breakpoints.  Make the break output prettier for Exception breakpoints.

llvm-svn: 152081

llvm-svn: 152053

Add SBFrame::IsEqual(const SBFrame &that) method and export it to the Python binding.
Alos add a test case test_frame_api_IsEqual() to TestFrames.py file.

llvm-svn: 152050

fixed a few potential NULL-pointer derefs in ValueObject
we have a way to provide docstrings for properties we add to the SWIG layer - a few of these properties have a docstring already, more will come in future commits
added a new bunch of properties to SBData to make it more natural and Python-like to access the data they contain

 NSTimeZone and CFTimeZonRef
 SEL and related types
 CFGregorianDate

llvm-svn: 151866

(b) fixes and improvements to the formatters for NSDate and NSString
(c) adding an introspection formatter for NSCountedSet
(d) making the Objective-C formatters test cases pass on both 64 and 32 bit
    one of the test cases is marked as expected failure on i386 - support needs to be added to the LLDB core for it to pass

llvm-svn: 151826

allocations by section.  We install these sections
in the target process and inform the JIT of their
new locations.

Also removed some unused variable warnings.

llvm-svn: 151789

 a) adds a Python summary provider for NSDate
 b) changes the initialization for ScriptInterpreter so that we are not passing a bulk of Python-specific function pointers around
 c) provides a new ScriptInterpreterObject class that allows for ref-count safe wrapping of scripting objects on the C++ side
 d) contains much needed performance improvements:
    1) the pointer to the Python function generating a scripted summary is now cached instead of looked up every time
    2) redundant memory reads in the Python ObjC runtime wrapper are eliminated
    3) summaries now use the m_summary_str in ValueObject to store their data instead of passing around ( == copying) an std::string object
 e) contains other minor fixes, such as adding descriptive error messages for some cases of summary generation failure

will fill out either a SBLaunchInfo or SBAttachInfo class, then call:

SBProcess SBTarget::Launch (SBLaunchInfo &, SBError &);
SBProcess SBTarget::Attach (SBAttachInfo &, SBError &);

The attach is working right now and allows the ability to set many filters such
as the parent process ID, the user/group ID, the effective user/group ID, and much
more.

The launch is not yet working, but I will get this working soon. By changing our
launch and attach calls to take an object, it allows us to add more capabilities to
launching and attaching without having to have launch and attach functions that
take more and more arguments. 

Once this is all working we will deprecated the older launch and attach fucntions
and eventually remove them.

llvm-svn: 151344

Intel disassembler usable.

Also flipped the switch: we are now exclusively
using Disassembler.h instead of
EnhancedDisassembly.h for all disassembly in
LLDB.

llvm-svn: 151306

The formatter for NSString is an improved version of the one previously shipped as an example, the others are new in design and implementation.
A more robust and OO-compliant Objective-C runtime wrapper is provided for runtime versions 1 and 2 on 32 and 64 bit.
The formatters are contained in a category named "AppKit", which is not enabled at startup.

llvm-svn: 151299

typemaps to allow Python to invoke the new SBModule::GetVersion() API. Memory management is taken care of automatically so that Python users can simply say my_list = my_module.GetVersion() and receive a new list with the version numbers, if any, inside.

subclasses if the object files support version numbering. Exposed
this through SBModule for upcoming data formatter version checking stuff.

Change build-swig-Python.sh to emit an empty LLDBPythonWrap.cpp file if 
this build is LLDB_DISABLE_PYTHON.

Change the "Copy to Xcode.app" shell script phase in the lldb.xcodeproj
to only do this copying for Mac native builds.

llvm-svn: 151035

Also add SB API's to set this callback, and to enable the log channels.

llvm-svn: 151018

Adding formatters for several useful Objective-C/Cocoa data types. The new categories are not enabled at startup, but can be manually activated if desired.
Adding new API calls to SBValue to be able to retrieve the associated formatters
Some refactoring to FormatNavigator::Get() in order to shrink its size down to more manageable terms (a future, massive, refactoring effort will still be needed)
Test cases added for the above

llvm-svn: 150784

<rdar://problem/10619974>

llvm-svn: 150665

New public API for handling formatters: creating, deleting, modifying categories, and formatters, and managing type/formatter association.
This provides SB classes for each of the main object types involved in providing formatter support:
 SBTypeCategory
 SBTypeFilter
 SBTypeFormat
 SBTypeSummary
 SBTypeSynthetic
plus, an SBTypeNameSpecifier class that is used on the public API layer to abstract the notion that formatters can be applied to plain type-names as well as to regular expressions
For naming consistency, this patch also renames a lot of formatters-related classes.
Plus, the changes in how flags are handled that started with summaries is now extended to other classes as well. A new enum (lldb::eTypeOption) is meant to support this on the public side.
The patch also adds several new calls to the formatter infrastructure that are used to implement by-index accessing and several other design changes required to accommodate the new API layer.
An architectural change is introduced in that backing objects for formatters now become writable. On the public API layer, CoW is implemented to prevent unwanted propagation of changes.
Lastly, there are some modifications in how the "default" category is constructed and managed in relation to other categories.

llvm-svn: 150558

change (besides logging) is that now string
literals in the IR are ConstantDataArrays instead
of ConstantArrays.

llvm-svn: 150142

Also, provide and use accessors for the thread options on breakpoints so we
can control sending the appropriate events.

interface (.i) files for each class.

Changed the FindFunction class from:

uint32_t
SBTarget::FindFunctions (const char *name, 
                         uint32_t name_type_mask, 
                         bool append, 
                         lldb::SBSymbolContextList& sc_list)

uint32_t
SBModule::FindFunctions (const char *name, 
                         uint32_t name_type_mask, 
                         bool append, 
                         lldb::SBSymbolContextList& sc_list)

To:

lldb::SBSymbolContextList
SBTarget::FindFunctions (const char *name, 
                         uint32_t name_type_mask = lldb::eFunctionNameTypeAny);

lldb::SBSymbolContextList
SBModule::FindFunctions (const char *name,
                         uint32_t name_type_mask = lldb::eFunctionNameTypeAny);

This makes the API easier to use from python. Also added the ability to
append a SBSymbolContext or a SBSymbolContextList to a SBSymbolContextList.

Exposed properties for lldb.SBSymbolContextList in python:

lldb.SBSymbolContextList.modules => list() or all lldb.SBModule objects in the list
lldb.SBSymbolContextList.compile_units => list() or all lldb.SBCompileUnits objects in the list
lldb.SBSymbolContextList.functions => list() or all lldb.SBFunction objects in the list
lldb.SBSymbolContextList.blocks => list() or all lldb.SBBlock objects in the list
lldb.SBSymbolContextList.line_entries => list() or all lldb.SBLineEntry objects in the list
lldb.SBSymbolContextList.symbols => list() or all lldb.SBSymbol objects in the list

This allows a call to the SBTarget::FindFunctions(...) and SBModule::FindFunctions(...)
and then the result can be used to extract the desired information:

sc_list = lldb.target.FindFunctions("erase")

for function in sc_list.functions:
    print function
for symbol in sc_list.symbols:
    print symbol

Exposed properties for the lldb.SBSymbolContext objects in python:

lldb.SBSymbolContext.module => lldb.SBModule
lldb.SBSymbolContext.compile_unit => lldb.SBCompileUnit
lldb.SBSymbolContext.function => lldb.SBFunction
lldb.SBSymbolContext.block => lldb.SBBlock
lldb.SBSymbolContext.line_entry => lldb.SBLineEntry
lldb.SBSymbolContext.symbol => lldb.SBSymbol


Exposed properties for the lldb.SBBlock objects in python:

lldb.SBBlock.parent => lldb.SBBlock for the parent block that contains
lldb.SBBlock.sibling => lldb.SBBlock for the sibling block to the current block
lldb.SBBlock.first_child => lldb.SBBlock for the first child block to the current block
lldb.SBBlock.call_site => for inline functions, return a lldb.declaration object that gives the call site file, line and column
lldb.SBBlock.name => for inline functions this is the name of the inline function that this block represents
lldb.SBBlock.inlined_block => returns the inlined function block that contains this block (might return itself if the current block is an inlined block)
lldb.SBBlock.range[int] => access the address ranges for a block by index, a list() with start and end address is returned
lldb.SBBlock.ranges => an array or all address ranges for this block
lldb.SBBlock.num_ranges => the number of address ranges for this blcok

SBFunction objects can now get the SBType and the SBBlock that represents the
top scope of the function.

SBBlock objects can now get the variable list from the current block. The value
list returned allows varaibles to be viewed prior with no process if code
wants to check the variables in a function. There are two ways to get a variable
list from a SBBlock:

lldb::SBValueList
SBBlock::GetVariables (lldb::SBFrame& frame,
                       bool arguments,
                       bool locals,
                       bool statics,
                       lldb::DynamicValueType use_dynamic);

lldb::SBValueList
SBBlock::GetVariables (lldb::SBTarget& target,
                       bool arguments,
                       bool locals,
                       bool statics);

When a SBFrame is used, the values returned will be locked down to the frame
and the values will be evaluated in the context of that frame.

When a SBTarget is used, global an static variables can be viewed without a
running process.

llvm-svn: 149853

Fixed "target modules list" (aliased to "image list") to output more information
by default. Modified the "target modules list" to have a few new options:

"--header" or "-h" => show the image header address
"--offset" or "-o" => show the image header address offset from the address in the file (the slide applied to the shared library)

Removed the "--symfile-basename" or "-S" option, and repurposed it to 
"--symfile-unique" "-S" which will show the symbol file if it differs from
the executable file.

ObjectFile's can now be loaded from memory for cases where we don't have the
files cached locally in an SDK or net mounted root. ObjectFileMachO can now
read mach files from memory.

Moved the section data reading code into the ObjectFile so that the object
file can get the section data from Process memory if the file is only in
memory.

lldb_private::Module can now load its object file in a target with a rigid 
slide (very common operation for most dynamic linkers) by using:

bool 
Module::SetLoadAddress (Target &target, lldb::addr_t offset, bool &changed)

lldb::SBModule() now has a new constructor in the public interface:

SBModule::SBModule (lldb::SBProcess &process, lldb::addr_t header_addr);

This will find an appropriate ObjectFile plug-in to load an image from memory
where the object file header is at "header_addr".

llvm-svn: 149804

LLVM/Clang.  This brings in several fixes, including:

- Improvements in the Just-In-Time compiler's
  allocation of memory: the JIT now allocates
  memory in chunks of sections, improving its
  ability to generate relocations.  I have
  revamped the RecordingMemoryManager to reflect
  these changes, as well as to get the memory
  allocation and data copying out fo the
  ClangExpressionParser code.  Jim Grosbach wrote
  the updates to the JIT on the LLVM side.

- A new ExternalASTSource interface to allow LLDB to
  report accurate structure layout information to
  Clang.  Previously we could only report the sizes
  of fields, not their offsets.  This meant that if
  data structures included field alignment
  directives, we could not communicate the necessary
  alignment to Clang and accesses to the data would
  fail.  Now we can (and I have update the relevant
  test case).  Thanks to Doug Gregor for implementing
  the Clang side of this fix.

- The way Objective-C interfaces are completed by
  Clang has been made consistent with RecordDecls;
  with help from Doug Gregor and Greg Clayton I have
  ensured that this still works.

- I have eliminated all local LLVM and Clang patches,
  committing the ones that are still relevant to LLVM
  and Clang as needed.

I have tested the changes extensively locally, but
please let me know if they cause any trouble for you.

llvm-svn: 149775

Changed the lldb.SBModule.section[<str>] property to return a single section.

Added a lldb.SBSection.addr property which returns an lldb.SBAddress object.

llvm-svn: 149755

instead of the __repr__. __repr__ is a function that should return an
expression that can be used to recreate an python object and we were using
it to just return a human readable string.

Fixed a crasher when using the new implementation of SBValue::Cast(SBType).

Thread hardened lldb::SBValue and lldb::SBWatchpoint and did other general
improvements to the API.

Fixed a crasher in lldb::SBValue::GetChildMemberWithName() where we didn't
correctly handle not having a target.

llvm-svn: 149743

lldb.SBValueList now exposes the len() method and also allows item access:

lldb.SBValueList[<int>] - where <int> is an integer index into the list, returns a single lldb.SBValue which might be empty if the index is out of range
lldb.SBValueList[<str>] - where <str> is the name to look for, returns a list() of lldb.SBValue objects with any matching values (the list might be empty if nothing matches)
lldb.SBValueList[<re>]  - where <re> is a compiles regular expression, returns a list of lldb.SBValue objects for containing any matches or a empty list if nothing matches

lldb.SBFrame now exposes:

lldb.SBFrame.variables => SBValueList of all variables that are in scope
lldb.SBFrame.vars => see lldb.SBFrame.variables
lldb.SBFrame.locals => SBValueList of all variables that are locals in the current frame
lldb.SBFrame.arguments => SBValueList of all variables that are arguments in the current frame
lldb.SBFrame.args => see lldb.SBFrame.arguments
lldb.SBFrame.statics => SBValueList of all static variables
lldb.SBFrame.registers => SBValueList of all registers for the current frame
lldb.SBFrame.regs => see lldb.SBFrame.registers

Combine any of the above properties with the new lldb.SBValueList functionality
and now you can do:

y = lldb.frame.vars['rect.origin.y']

or

vars = lldb.frame.vars
for i in range len(vars):
  print vars[i]

Also expose "lldb.SBFrame.var(<str>)" where <str> can be en expression path
for any variable or child within the variable. This makes it easier to get a
value from the current frame like "rect.origin.y". The resulting value is also
not a constant result as expressions will return, but a live value that will
continue to track the current value for the variable expression path.

lldb.SBValue now exposes:

lldb.SBValue.unsigned => unsigned integer for the value
lldb.SBValue.signed => a signed integer for the value

llvm-svn: 149684

llvm-svn: 149673

lldb.SBModule.section and lldb.SBModule.sections property access.

llvm-svn: 149665

uint32_t
SBType::GetNumberOfTemplateArguments ();

lldb::SBType
SBType::GetTemplateArgumentType (uint32_t idx);

lldb::TemplateArgumentKind
SBType::GetTemplateArgumentKind (uint32_t idx);

Some lldb::TemplateArgumentKind values don't have a corresponding SBType
that will be returned from SBType::GetTemplateArgumentType(). This will
help our data formatters do their job by being able to find out the
type of template params and do smart things with those.

llvm-svn: 149658

ensure that changes to the typemaps are properly detected and cause SWIG to rebuild LLDBWrapPython.cpp

llvm-svn: 149606

negative hex values. Also added a very rudimentary version of the == and !=
operators to the lldb.value helper class.

llvm-svn: 149564

You can now access a frame in a thread using:

lldb.SBThread.frame[int] -> lldb.SBFrame object for a frame in a thread

Where "int" is an integer index. You can also access a list object with all of
the frames using:

lldb.SBThread.frames => list() of lldb.SBFrame objects

All SB objects that give out SBAddress objects have properties named "addr"

lldb.SBInstructionList now has the following convenience accessors for len() and
instruction access using an index:

insts = lldb.frame.function.instructions
for idx in range(len(insts)):
    print insts[idx]
    
Instruction lists can also lookup an isntruction using a lldb.SBAddress as the key:

pc_inst = lldb.frame.function.instructions[lldb.frame.addr]

lldb.SBProcess now exposes:

lldb.SBProcess.is_alive => BOOL Check if a process is exists and is alive
lldb.SBProcess.is_running => BOOL check if a process is running (or stepping):
lldb.SBProcess.is_running => BOOL check if a process is currently stopped or crashed:
lldb.SBProcess.thread[int] => lldb.SBThreads for a given "int" zero based index
lldb.SBProcess.threads => list() containing all lldb.SBThread objects in a process

SBInstruction now exposes:
lldb.SBInstruction.mnemonic => python string for instruction mnemonic
lldb.SBInstruction.operands => python string for instruction operands
lldb.SBInstruction.command => python string for instruction comment

SBModule now exposes:

lldb.SBModule.uuid => uuid.UUID(), an UUID object from the "uuid" python module
lldb.SBModule.symbol[int] => lldb.Symbol, lookup symbol by zero based index
lldb.SBModule.symbol[str] => list() of lldb.Symbol objects that match "str"
lldb.SBModule.symbol[re] => list() of lldb.Symbol objecxts that match the regex
lldb.SBModule.symbols => list() of all symbols in a module

  
SBAddress objects can now access the current load address with the "lldb.SBAddress.load_addr"
property. The current "lldb.target" will be used to try and resolve the load address.

Load addresses can also be set using this accessor:

addr = lldb.SBAddress()
addd.load_addr = 0x123023

Then you can check the section and offset to see if the address got resolved.

SBTarget now exposes:

lldb.SBTarget.module[int] => lldb.SBModule from zero based module index
lldb.SBTarget.module[str] => lldb.SBModule by basename or fullpath or uuid string
lldb.SBTarget.module[uuid.UUID()] => lldb.SBModule whose UUID matches
lldb.SBTarget.module[re] => list() of lldb.SBModule objects that match the regex
lldb.SBTarget.modules => list() of all lldb.SBModule objects in the target

SBSymbol now exposes:

lldb.SBSymbol.name => python string for demangled symbol name
lldb.SBSymbol.mangled => python string for mangled symbol name or None if there is none
lldb.SBSymbol.type => lldb.eSymbolType enum value
lldb.SBSymbol.addr => SBAddress object that represents the start address for this symbol (if there is one)
lldb.SBSymbol.end_addr => SBAddress for the end address of the symbol  (if there is one)
lldb.SBSymbol.prologue_size => pythin int containing The size of the prologue in bytes
lldb.SBSymbol.instructions => SBInstructionList containing all instructions for this symbol

SBFunction now also has these new properties in addition to what is already has:
lldb.SBFunction.addr => SBAddress object that represents the start address for this function
lldb.SBFunction.end_addr => SBAddress for the end address of the function
lldb.SBFunction.instructions => SBInstructionList containing all instructions for this function

SBFrame now exposes the SBAddress for the frame:
lldb.SBFrame.addr => SBAddress which is the section offset address for the current frame PC

These are all in addition to what was already added. Documentation and website
updates coming soon.

llvm-svn: 149489

Added a new convenience property on lldb.SBThread names "frames" which always returns a complete list of all lldb.SBFrame objects:

(lldb) script
>>> frames = lldb.thread.frames
>>> for frame in frames:
...   print frame

Also changed all of the "__repr__" methods to strip any trailing newline characters so we don't end up with entra newlines.
