Jim Ingham 70f11f88e3 Make a way to set the result status for Python defined commands, and don't overwrite the status of the result if
the python command has set it.

Jim Ingham 5a98841673 Make raw & parsed commands subclasses of CommandObject rather than having the raw version implement an
Execute which was never going to get run and another ExecuteRawCommandString.  Took the knowledge of how
to prepare raw & parsed commands out of CommandInterpreter and put it in CommandObject where it belongs.

Also took all the cases where there were the subcommands of Multiword commands declared in the .h file for
the overall command and moved them into the .cpp file.

Made the CommandObject flags work for raw as well as parsed commands.

Made "expr" use the flags so that it requires you to be paused to run "expr".

Johnny Chen b90827e66c rdar://problem/11584012
Refactorings of watchpoint creation APIs so that SBTarget::WatchAddress(), SBValue::Watch(), and SBValue::WatchPointee()
now take an additional 'SBError &error' parameter (at the end) to contain the reason if there is some failure in the
operation.  Update 'watchpoint set variable/expression' commands to take advantage of that.

Update existing test cases to reflect the API change and add test cases to verify that the SBError mechanism works for
SBTarget::WatchAddress() by passing an invalid watch_size.

Enrico Granata 07a4ac22ed <rdar://problem/11239650> Fixing a bug where the SetValueFromCString() method failed to operate on dynamic values. The fix consists in making the set operation fall through to the parent. We only actually allow this if the dynamic value is at a 0-offset from the parent, or the new value is 0. Other scenarios would need agreement on the actual meaning of the set operation (do we keep offsetting? do we just assume the user knows what they are doing?) so we prevent them, and let the expression parser deal with the complexity

Enrico Granata d50f18b1a0 Part 1 of a series of fixes meant to improve reliability and increase ease of bug fixing for data formatter issues.
We are introducing a new Logger class on the Python side. This has the same purpose, but is unrelated, to the C++ logging facility
The Pythonic logging can be enabled by using the following scripting commands:
(lldb) script Logger._lldb_formatters_debug_level = {0,1,2,...}
0 = no logging
1 = do log
2 = flush after logging each line - slower but safer
3 or more = each time a Logger is constructed, log the function that has created it
more log levels may be added, each one being more log-active than the previous
by default, the log output will come out on your screen, to direct it to a file:
(lldb) script Logger._lldb_formatters_debug_filename = 'filename'
that will make the output go to the file - set to None to disable the file output and get screen logging back
Logging has been enabled for the C++ STL formatters and for Cocoa class NSData - more logging will follow


synthetic children providers for classes list and map (both libstdcpp and libcxx) now have internal capping for safety reasons
this will fix crashers where a malformed list or map would not ever meet our termination conditions

to set the cap to a different value:

(lldb) script {gnu_libstdcpp|libcxx}.{map|list}_capping_size = new_cap (by default, it is 255)

you can optionally disable the loop detection algorithm for lists

(lldb) script {gnu_libstdcpp|libcxx}.list_uses_loop_detector = False

Enrico Granata bf70ee97b1 adding a summary for Objective-C type 'Class'
llvm-svn: 153541
2012-03-27 21:49:20 +00:00
Enrico Granata c5bc412cf6 Synthetic values are now automatically enabled and active by default. SBValue is set up to always wrap a synthetic value when one is available.
A new setting enable-synthetic-value is provided on the target to disable this behavior.
There also is a new GetNonSyntheticValue() API call on SBValue to go back from synthetic to non-synthetic. There is no call to go from non-synthetic to synthetic.
The test suite has been changed accordingly.
Fallout from changes to type searching: an hack has to be played to make it possible to use maps that contain std::string due to the special name replacement operated by clang
Fixing a test case that was using libstdcpp instead of libc++ - caught as a consequence of said changes to type searching

2012-03-27 02:35:13 +00:00
Enrico Granata 86027e954c Adding a new API call IsTypeComplete() to SBType. This call is meant to check if the type has been previously completed or not (which is mostly interesting from a performance point of view)
Adding a test case that checks that we do not complete types before due time. This should help us track cases similar to the cascading data formatters.

Enrico Granata 86cc982974 Massive enumeration name changes: a number of enums in ValueObject were not following the naming pattern
Changes to synthetic children:
 - the update(self): function can now (optionally) return a value - if it returns boolean value True, ValueObjectSyntheticFilter will not clear its caches across stop-points
   this should allow better performance for Python-based synthetic children when one can be sure that the child ValueObjects have not changed
 - making a difference between a synthetic VO and a VO with a synthetic value: now a ValueObjectSyntheticFilter will not return itself as its own synthetic value, but will (correctly)
   claim to itself be synthetic
 - cleared up the internal synthetic children architecture to make a more consistent use of pointers and references instead of shared pointers when possible
 - major cleanup of unnecessary #include, data and functions in ValueObjectSyntheticFilter itself
 - removed the SyntheticValueType enum and replaced it with a plain boolean (to which it was equivalent in the first place)
Some clean ups to the summary generation code
Centralized the code that clears out user-visible strings and data in ValueObject
More efficient summaries for libc++ containers

llvm-svn: 152952
2012-03-16 21:55:42 +00:00
Enrico Granata c7f873064b Added formatters for libc++ (http://libcxx.llvm.org):
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

Enrico Granata 7bc0ec3aad This commit:
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

llvm-svn: 151392
2012-02-24 20:59:25 +00:00
Greg Clayton 0e615684bb Added the new way we will eventually do all attaches and launches. First clients
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.

Enrico Granata d3d444f811 This patch provides a set of formatters for most of the commonly used Cocoa classes.
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.

Enrico Granata 061858ce61 <rdar://problem/10062621>
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.

Greg Clayton 5569e64ea7 Removed all of the "#ifndef SWIG" from the SB header files since we are using
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.

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".

Greg Clayton 819134a7c4 Allow a SBAddress to be created from a SBSection and an offset.
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
2012-02-04 02:58:17 +00:00
Greg Clayton 81e871ed76 Convert all python objects in our API to use overload the __str__ method
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
2012-02-04 02:27:34 +00:00
Greg Clayton 7edbdfc97c Expose more convenience functionality in the python classes.
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
2012-02-03 07:02:37 +00:00
Greg Clayton 9a142cf84d Fixed casting in the lldb::SBValue::Cast(SBType) function.
llvm-svn: 149673
2012-02-03 05:34:10 +00:00
Greg Clayton b62bb8cedc Cleaned up the documentation strings for many helper objects and added
lldb.SBModule.section and lldb.SBModule.sections property access.

llvm-svn: 149665
2012-02-03 03:22:53 +00:00
Greg Clayton 402230e633 Added support to SBType for getting template arguments from a SBType:
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.

2012-02-02 17:26:00 +00:00
Greg Clayton 43484c5cd7 When outputting hex values use unsigned integer values so we don't get
negative hex values. Also added a very rudimentary version of the == and !=
operators to the lldb.value helper class.

llvm-svn: 149564
2012-02-02 00:12:47 +00:00
Greg Clayton 6b2bd93918 Added many more python convenience accessors:
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
2012-02-01 08:09:32 +00:00
Greg Clayton 2415586faa 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.

llvm-svn: 149466
2012-02-01 02:30:27 +00:00
Greg Clayton 05e8d19446 Added a new class to the lldb python module:
lldb.value()

It it designed to be given a lldb.SBValue object and it allows natural
use of a variable value:

    pt = lldb.value(lldb.frame.FindVariable("pt"))
    print pt
    print pt.x
    print pt.y

    pt = lldb.frame.FindVariable("rectangle_array")
    print rectangle_array[12]
    print rectangle_array[5].origin.x

Note that array access works just fine and works on arrays or pointers:

pt = lldb.frame.FindVariable("point_ptr")
print point_ptr[5].y

Also note that pointer child accesses are done using a "." instead of "->":

print point_ptr.x

2012-02-01 01:46:19 +00:00
Greg Clayton fbf1b64173 Added fuzz testing for when we call API calls with an invalid object.
We previously weren't catching that SBValue::Cast(...) would crash
if we had an invalid (empty) SBValue object.

2011-12-15 22:34:59 +00:00
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.

llvm-svn: 146640
2011-12-15 04:38:41 +00:00
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

In the future, this API will also allow clients

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.

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

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

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.

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.
