You can either provide the function name, or function body text.
Also propagate the compilation error up from where it is checked so we can report compilation errors.

These changes were written by Greg Clayton, Jim Ingham, Jason Molenda.
It builds cleanly against TOT llvm with xcodebuild. I updated the
cmake files by visual inspection but did not try a build. I haven't
built these sources on any non-Mac platforms - I don't think this
patch adds any code that requires darwin, but please let me know if
I missed something.
In debugserver, MachProcess.cpp and MachTask.cpp were renamed to
MachProcess.mm and MachTask.mm as they picked up some new Objective-C
code needed to launch processes when running on iOS.

changing the data it returns; this change accepts either the old format or
the new format. It doesn't yet benefit from the new format's additions -
but I need to get this checked in so we aren't rev-locked.
Also add a missing .i entry for SBQueue::GetNumRunningItems() missing from
the last checkin.

Also remove SetStopOthers from the ThreadPlanCallFunction, because if the value you have doesn't match what is
in the EvaluateExpressionOptions the plan was passed when created it won't work correctly.

libldi library to collect extended backtrace information; switch
to the libBacktraceRecording library and its APIs. Complete the
work of adding QueueItems to Queues and allow for the QueueItems
to be interrogated about their extended backtraces in turn.
There's still cleanup and documentation to do on this code but the
code is functional and I it's a good time to get the work-in-progress
checked in.

The many many benefits include:
1 - Input/Output/Error streams are now handled as real streams not a push style input
2 - auto completion in python embedded interpreter
3 - multi-line input for "script" and "expression" commands now allow you to edit previous/next lines using up and down arrow keys and this makes multi-line input actually a viable thing to use
4 - it is now possible to use curses to drive LLDB (please try the "gui" command)
We will need to deal with and fix any buildbot failures and tests and arise now that input/output and error are correctly hooked up in all cases.

SBType SBType::GetTypedefedType();
Also added the ability to get a type by type ID from a SBModule:
SBType SBModule::GetTypeByID (lldb::user_id_t uid);
llvm-svn: 199939
The "type format add" command gets a new flag --type (-t). If you pass -t <sometype>, upon fetching the value for an object of your type,
LLDB will display it as-if it was of enumeration type <sometype>
This is useful in cases of non-contiguous enums where there are empty gaps of unspecified values, and as such one cannot type their variables as the enum type,
but users would still like to see them as-if they were of the enum type (e.g. DWARF field types with their user-reserved ranges)
The SB API has also been improved to handle both types of formats, and a test case is added

This patch adds a new lldb_private::SectionLoadHistory class that tracks what shared libraries were loaded given a process stop ID. This allows us to keep a history of the sections that were loaded for a time T. Many items in history objects will rely upon the process stop ID in the future.

Example code:
remote_platform = lldb.SBPlatform("remote-macosx");
remote_platform.SetWorkingDirectory("/private/tmp")
debugger.SetSelectedPlatform(remote_platform)
connect_options = lldb.SBPlatformConnectOptions("connect://localhost:1111");
err = remote_platform.ConnectRemote(connect_options)
if err.Success():
print >> result, 'Connected to remote platform:'
print >> result, 'hostname: %s' % (remote_platform.GetHostname())
src = lldb.SBFileSpec("/Applications/Xcode.app/Contents/SharedFrameworks/LLDB.framework", False)
dst = lldb.SBFileSpec()
# copy src to platform working directory since "dst" is empty
err = remote_platform.Install(src, dst);
if err.Success():
print >> result, '%s installed successfully' % (src)
else:
print >> result, 'error: failed to install "%s": %s' % (src, err)
Implemented many calls needed in lldb-platform to be able to install a directory that contains symlinks, file and directories.
The remote lldb-platform can now launch GDB servers on the remote system so that remote debugging can be spawned through the remote platform when connected to a remote platform.
The API in SBPlatform is subject to change and will be getting many new functions.

(and same thing to Thread base class) which can be used when looking
at an ExtendedBacktrace thread; it will try to find the IndexID() of
the original thread that was executing this backtrace when it was
recorded. If lldb can't find a record of that thread, it will return
the same value as IndexID() for the ExtendedBacktrace thread.

It completes the job of using EvaluateExpressionOptions consistently throughout
the inferior function calling mechanism in lldb begun in Greg's patch r194009.
It removes a handful of alternate calls into the ClangUserExpression/ClangFunction/ThreadPlanCallFunction which
were there for convenience. Using the EvaluateExpressionOptions removes the need for them.
Using that it gets the --debug option from Greg's patch to work cleanly.
It also adds another EvaluateExpressionOption to not trap exceptions when running expressions. You shouldn't
use this option unless you KNOW your expression can't throw beyond itself. This is:
<rdar://problem/15374885>
At present this is only available through the SB API's or python.
It fixes a bug where function calls would unset the ObjC & C++ exception breakpoints without checking whether
they were set by somebody else already.

Implement SBTarget::CreateValueFromAddress() with a behavior equivalent to SBValue::CreateValueFromAddress()
(but without the need to grab an SBValue first just as a starting point to make up another SBValue out of whole cloth)
llvm-svn: 192239
This allows the PC to be directly changed to a different line.
It's similar to the example python script in examples/python/jump.py, except implemented as a builtin.
Also this version will track the current function correctly even if the target line resolves to multiple addresses. (e.g. debugging a templated function)
llvm-svn: 190572
There are two new classes:
lldb::SBModuleSpec
lldb::SBModuleSpecList
The SBModuleSpec wraps up a lldb_private::ModuleSpec, and SBModuleSpecList wraps up a lldb_private::ModuleSpecList.

The semi-unofficial way of returning a status from a Python command was to return a string (e.g. return "no such variable was found") that LLDB would pick as a clue of an error having happened
This checkin changes that:
- SBCommandReturnObject now exports a SetError() call, which can take an SBError or a plain C-string
- script commands now drop any return value and expect the SBCommandReturnObject ("return object") to be filled in appropriately - if you do nothing, a success will be assumed
If your commands were relying on returning a value and having LLDB pick that up as an error, please change your commands to SetError() through the return object or expect changes in behavior
llvm-svn: 184893
The script was able to point out and save 40 bytes in each lldb_private::Section by being very careful where we need to have virtual destructors and also by re-ordering members.

lldb::SBTypeList
SBCompileUnit::GetTypes (uint32_t type_mask = lldb::eTypeClassAny);
This lets you request types by filling out a mask that contains one or more bits from the lldb::TypeClass enumerations, so you can only get the types you really want.

- exposing new accessors: formats/format, ..., that allow you to iterate over all formatters

Providing a Python helper SBData.CreateDataFromInt() to make an SBData out of a single integer number
It tries to use the current target, if any, for endianness and pointer size, and it picks a reasonable size on your behalf - if there is no way it can infer anything reasonable it essentially picks a 64-bit Mac as the reference model

SWIG is smart enough to recognize that C++ operators == and != mean __eq__ and __ne__ in Python and do the appropriate translation
But it is not smart enough to recognize that mySBObject == None should return False instead of erroring out
The %pythoncode blocks are meant to provide those extra smarts (and they play some SWIG&Python magic to find the right function to call behind the scenes with no risk of typos :-)
Lastly, SBBreakpoint provides an == but never provided a != operator - common courtesy is to provide both

Introducing a negative cache for ObjCLanguageRuntime::LookupInCompleteClassCache()
This helps speed up the (common) case of us looking for classes that are hidden deep within Cocoa internals and repeatedly failing at finding type information for them.
In order for this to work, we need to clean this cache whenever debug information is added. A new symbols loaded event is added that is triggered with add-dsym (before modules loaded would be triggered for both adding modules and adding symbols).
Interested parties can register for this event. Internally, we make sure to clean the negative cache whenever symbols are added.
Lastly, ClassDescriptor::IsTagged() has been refactored to GetTaggedPointerInfo() that also (optionally) returns info and value bits. In this way, data formatters can share tagged pointer code instead of duplicating the required arithmetic.

"compile_units" returns an array of all compile units in a module as a list() of lldb.SBCompileUnit objects.
"compile_unit" returns a compile unit accessor object that allows indexed access, search by full or partial path, or by regex:
(lldb) script
comp_unit = lldb.target.module['TextEdit'].compile_unit['Document.m']
comp_unit = lldb.target.module['TextEdit'].compile_unit['/path/to/Document.m']
comp_unit = lldb.target.module['TextEdit'].compile_unit[0]
comp_unit = lldb.target.module['TextEdit'].compile_unit[1]
for comp_unit in lldb.target.module['TextEdit'].compile_unit[re.compile("\.m$")]
print comp_unit
This helps do quick searches and scripting while debugging.
