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'

This means that "register read stmm0 --format f" actually works now.

This is a little messy but LLDB assumes 'long double' is portable, when it is not.

- Addresses review comments from Stefanus!

llvm-svn: 187816

- Thanks to Matt Kopec for noticing the failure!

llvm-svn: 187815

- update TestThreadStepOut.py to work with Intel compilers
- fix typo in TestConcurrentEvents

mapping of source to assembly so that the same test script can be used
with more compilers.

Patch by Andy Kaylor!

Also marks the LLDB test of template parameters as xfail on icc.

Also update comment in const variables test to reflect ICC status.

llvm-svn: 187501

Set an extra debug flag when testing with ICC so that it generates the correct debug info for inlined tests.

llvm-svn: 187500

- disable some TestConcurrentEvents cases (which are affected by llvm.org/pr16714 -- watchpoints in multithreaded programs)
- relax number-of-bp-locations check in TestUniqueTypes/TestUnsignedTypes
- skip TestDataFormatterStdVector cases with GCC 4.8 (known failure due to llvm.org/pr15301)
- workaround for race condition in TestHelloWorld.py
- update TestSettings.py to work on distros (like Fedora) that have /bin/cat hardlinked to /usr/bin/cat

After these changes, the test suite should run cleanly against GCC 4.8 (with DWARF v4)!

These tests fail on FreeBSD due to missing build support, the same reason
they fail on Linux.

llvm-svn: 187416

llvm-svn: 187415

- newer gcc generates additional debuginfo for function exit (stack object desctruction) which was causing tests to fail
- work-around consists of not declaring any stack objects in main()

llvm-svn: 187389

FreeBSD's Host class doesn't yet return a list of running processes,
so 'platform process list' fails and attach by process name does not
work.

llvm-svn: 187142

Watchpoints are not yet working on FreeBSD

llvm-svn: 187134

Live debugging for threaded inferiors is not yet implemented on FreeBSD

llvm-svn: 187131

-dead_strip isn't supported by FreeBSD's ld.

llvm-svn: 187129

Live debugging of threaded inferiors is currently unimplemented for
FreeBSD.

because a synthetic symbol hasn't been provided for stripped function symbols.

llvm-svn: 186959

llvm-svn: 186717

Your mileage may vary depending on the gcc and stl versions in use (see llvm.org/pr15301).

and -fomit-frame-pointer.

- Parses eh_frame FDEs to determine the function address and size so that
the call frame parsing can continue.

Note: This code path is specific to ELF and PECOFF, because ObjectFileMachO
uses LCT_FunctionStarts to efficiently populate the symbol table.

Thanks to Jason Molenda for the review!

- test with python API
- test with command interpreter
- test stepping a single (selected) thread
- test stepping all threads in the program

llvm-svn: 186446

Adds a passing test for step-over and step-out when the inferior is about to call longjmp (non-local goto) in a single-threaded inferior.

llvm-svn: 186325

Work-around for GCC issue where setting a breakpoint on a vector definition also adds a breakpoint on the d'tor call

llvm-svn: 186193

llvm-svn: 186166

take for threads created while the program is running.  Remove the testcase skips from TestConcurrentEvents.py,
since they all pass now, and fix TestWatchpointMultipleThreads.py - which should have caught this problem -
so it doesn't artificially break on new thread creation before the watchpoint triggers.

- Unable to reproduce llvm.org/pr16170 locally

llvm-svn: 186129

- thread count remains correct now that we use pthread_kill() instead of kill() to deliver signals

llvm-svn: 186126

- code cleanup, improved reporting when failures take place
- ensure known thread is interrupted by using pthread_kill() instead of kill() in the signal worker thread
- above should avoid llvm.org/pr16567 on Mac OS X (though kill() could still cause threads to pop out of existance temporarily)
- added an additional check that all threads have exited after worker threads are all join()ed
- logged llvm.org/pr16603 for the new Linux bug discovered

llvm-svn: 186124

Thanks to Daniel Malea for helping test this patch for Linux happiness!

llvm-svn: 185965

- re-enable tests fixed by Matt's commit this morning (addressed llvm.org/pr16567)
- disabled tests affected by new bug llvm.org/pr16575
- removed some commented out code in inferior

llvm-svn: 185951

llvm-svn: 185947

- Test verifies LLDB's handling of inferiors with threads that: hit breakpoints,
  modfiy variables that have watchpoints set, generate user signals, and crash.
- Add a few "stress tests" (with ~100 threads) -- run these with "-l" dotest.py
  flag.
- Fix stop_reason_to_str helper in lldbutil to handle eStopReasonThreadExited.
- Add sort_stopped_threads helper to lldbutil to separate thread lists based
  on stop reason.

Logged llvm.org/pr16566 and llvm.org/pr16567 for bugs exposed.
