Chris Bieneman aa098de715 [CMake] Generate LLDB_REVISION at build time
Summary:
This alters the generation of LLDB_REVISION to be heavily based on how clang generates its version header. There are two benefits of this aproach.

(1) The LLDB_REVISION is generated at build time, so it will be updated after an SCM pull/update even if CMake doesn't re-run
(2) This works on Windows

As noted this code is a simplified implementation of the code from clang.

Kate Stone b9c1b51e45 *** This commit represents a complete reformatting of the LLDB source code
*** to conform to clang-format’s LLVM style.  This kind of mass change has
*** two obvious implications:

Firstly, merging this particular commit into a downstream fork may be a huge
effort.  Alternatively, it may be worth merging all changes up to this commit,
performing the same reformatting operation locally, and then discarding the
merge for this particular commit.  The commands used to accomplish this
reformatting were as follows (with current working directory as the root of
the repository):

    find . \( -iname "*.c" -or -iname "*.cpp" -or -iname "*.h" -or -iname "*.mm" \) -exec clang-format -i {} +
    find . -iname "*.py" -exec autopep8 --in-place --aggressive --aggressive {} + ;

The version of clang-format used was 3.9.0, and autopep8 was 1.2.4.

Secondly, “blame” style tools will generally point to this commit instead of
a meaningful prior commit.  There are alternatives available that will attempt
to look through this change and find the appropriate prior commit.  YMMV.

Zachary Turner 3a00691f3d Move LLDB initialization/shutdown to Initialization.
This creates a new top-level folder called Initialization which
is intended to hold code specific to LLDB system initialization.
Currently this holds the Initialize() and Terminate() functions,
as well as the fatal error handler.

This provides a means to break the massive dependency cycle which
is caused by the fact that Debugger depends on Initialize and
Terminate which then depends on the entire LLDB project.  With
this structure, it will be possible for applications to invoke
lldb_private::Initialize() directly, and have that invoke
Debugger::Initialize.

Specifically, there were some functions for converting enums

Robert Flack f196c93172 Add Debugger::InitializeForLLGS to allow ref counted LLGS initialization.
After http://reviews.llvm.org/D8133 landed as r231550 process launch on remote platform stopped working.

This adds Debugger::InitializeForLLGS and tracks whether one or both of Initialize and InitializeForLLGS have been called, calling only the corresponding lldb_private::Terminate* methods as necessary. Since lldb_private::Terminate calls lldb_private::TerminateForLLGS, the latter method may be called twice if Initialize was called for both however the terminate methods ensure they are only called once after being initialized.

This still maintains the reduced binary size, though it does now technically link in lldb_private::Terminate on lldb-server even though this should never be called.

This should resolve the issue raised in http://reviews.llvm.org/D8133 where Debugger::Terminate assumed that there were 0 references to debugger and terminated early.

Ilia K 686b1fe65a Fix FileSpec::GetPath to return null-terminated strings
Summary:
Before this fix the FileSpec::GetPath() returned string which might be without '\0' at the end.
It could have happened if the size of buffer for path was less than actual path.

Test case:
```
FileSpec test("/path/to/file", false);
char buf[]="!!!!!!";
test.GetPath(buf, 3);
```

Before fix:
```
   233          FileSpec test("/path/to/file", false);
   234          char buf[]="!!!!!!";
   235          test.GetPath(buf, 3);
   236
-> 237          if (core_file)
   238          {
   239              if (!core_file.Exists())
   240              {
(lldb) print buf
(char [7]) $0 = "/pa!!!"
```

After fix:
```

   235          test.GetPath(buf, 3);

Zachary Turner 555a7a6ad2 Add a method to disable the Windows crash / assert dialogs.
When running the test suite on Windows, we can't have Windows popping
up dialogs when LLDB crashes in native code because it will hang
the test suite.  This patch silences those dialogs by checking an
environment variable at startup and configuring Windows based on
its value.

This patch also adds an environment variable to force inferiors to
never spawn in their own console window.  This is useful to prevent
new window spawm when running the test suite.

compact unwind encoding for normal frame-using functions is supported but it
will be easy handle frameless functions when I have a bit more free time to

correctly for functions from the compact unwind section.

This new code is very fresh -- it passes the lldb testsuite and I've done
by-hand inspection of many functions and am getting correct behavior for all
of them.  There may need to be some bug fixing over the next couple weeks as
I exercise and test it further.  But I think it's fine right now so I'm

 * Breakpoints don't work well on powerpc64.
 * Shared libraries don't yet get loaded for a 32-bit process on powerpc64 host.
 * Backtraces don't work.  This is due to PowerPC ABI using a backchain pointer
   in memory, instead of a dedicated frame pointer register for the backchain.
 * Breakpoints on functions without debug info may not work correctly for 32-bit
   powerpc.

Kuba Brecka afdf842b3f LLDB AddressSanitizer instrumentation runtime plugin, breakpint on error and report data extraction
Reviewed at http://reviews.llvm.org/D5592

This patch gives LLDB some ability to interact with AddressSanitizer runtime library, on top of what we already have (historical memory stack traces provided by ASan). Namely, that's the ability to stop on an error caught by ASan, and access the report information that are associated with it. The report information is also exposed into SB API.

More precisely this patch...

adds a new plugin type, InstrumentationRuntime, which should serve as a generic superclass for other instrumentation runtime libraries, these plugins get notified when modules are loaded, so they get a chance to "activate" when a specific dynamic library is loaded
an instance of this plugin type, AddressSanitizerRuntime, which activates itself when it sees the ASan dynamic library or founds ASan statically linked in the executable
adds a collection of these plugins into the Process class
AddressSanitizerRuntime sets an internal breakpoint on __asan::AsanDie(), and when this breakpoint gets hit, it retrieves the report information from ASan
this breakpoint is then exposed as a new StopReason, eStopReasonInstrumentation, with a new StopInfo subclass, InstrumentationRuntimeStopInfo
the StopInfo superclass is extended with a m_extended_info field (it's a StructuredData::ObjectSP), that can hold arbitrary JSON-like data, which is the way the new plugin provides the report data
the "thread info" command now accepts a "-s" flag that prints out the JSON data of a stop reason (same way the "-j" flag works now)
SBThread has a new API, GetStopReasonExtendedInfoAsJSON, which dumps the JSON string into a SBStream
adds a test case for all of this
I plan to also get rid of the original ASan plugin (memory history stack traces) and use an instance of AddressSanitizerRuntime for that purpose.

Daniel Malea e0f8f574c7 merge lldb-platform-work branch (and assorted fixes) into trunk
Summary:
    This merge brings in the improved 'platform' command that knows how to
    interface with remote machines; that is, query OS/kernel information, push
    and pull files, run shell commands, etc... and implementation for the new
    communication packets that back that interface, at least on Darwin based
    operating systems via the POSIXPlatform class. Linux support is coming soon.

    Verified the test suite runs cleanly on Linux (x86_64), build OK on Mac OS
    X Mountain Lion.

    Additional improvements (not in the source SVN branch 'lldb-platform-work'):
    - cmake build scripts for lldb-platform
    - cleanup test suite
    - documentation stub for qPlatform_RunCommand
    - use log class instead of printf() directly
    - reverted work-in-progress-looking changes from test/types/TestAbstract.py that work towards running the test suite remotely.
    - add new logging category 'platform'

RegisterContextCoreLinux_x86_64 inherits from RegisterContextLinux_x86_64 which inherits from RegisterContext_x86_64 which uses has:

   ProcessMonitor &GetMonitor();

This register context used by the core file can't use this since the process plug-in will be ProcessElfCore and the implementation of GetMonitor() does:

ProcessMonitor &
RegisterContext_x86_64::GetMonitor()
{
   ProcessSP base = CalculateProcess();
   ProcessPOSIX *process = static_cast<ProcessPOSIX*>(base.get());
   return process->GetMonitor();
}

ProcessELFCore doesn't, nor should it inherit from ProcessPOSIX and any call to GetMonitor() will fail for ELF core files.

Suggested cleanups:
- Make a register context class that is a base class that doesn't have any reading smarts, then make one that uses ProcessPOSIX and the has the GetMonitor() call, and one that gets its data straight from the core file.

Jason Molenda 1c627543f1 Add a new PlatformDarwinKernel for kernel debugging. This Platform
plugin will index the kext bundles on the local filesystem when
created.  During a kernel debug session, when the DynamicLoader
plugin needs to locate a kext by name like
"com.apple.com.apple.filesystems.autofs", the Platform can quickly
look for a UUID match in those kernel debug kit directories it
previously indexed.

I'm still working on profiling the performance impact of the inital
kext bundle scan; there will likely need to be a switch to enable
or disable this plugin's scan.

This only affects Mac kernel debugging and the code is only built
on Apple systems because of some use of low-level CoreFoundation
to parse plists.
