- 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.

Added a way to extract the module specifications from a file. A module specification is information that is required to describe a module (executable, shared library, object file, ect). This information includes host path, platform path (remote path), symbol file path, UUID, object name (for objects in .a files for example you could have an object name of "foo.o"), and target triple. Module specification can be used to create a module, or used to add a module to a target. A list of module specifications can be used to enumerate objects in container objects (like universal mach files and BSD archive files).

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.

Remove @expectedFailureGcc from TestInlineStepping as function prologue bug is not reproducible anymore.

llvm-svn: 185579

- should resolve remaining failures on clang buildbot

llvm-svn: 185576

- this issue was detected on recent GCC buildbot runs

- argparse_compat library does not support reading environment variables
- should unblock Linux GCC buildbot from running tests again

llvm-svn: 185567

- build fails due to PyCallable template definition inside an extern "C" scope

Import the builtin type prefix before we import the user expression prefix so that the user expression prefix can use the uint, int, size_t, and other types without having to define them.

ensure that the watchpoint not the step is reported as the stop reason.  Also, stash away & restore
the current stop reason just so it can't go away on us.

* Use PseudoTerminal to fix stdio handling / passthrough to the inferior
  process.
* Add log messages equivalent to the Linux ones.
* Port changes relating to process creation / termination.

The build system is currently miss-identifying GNU/kFreeBSD as FreeBSD.
This kind of simplification is sometimes useful, but in general it's not correct. 

As GNU/kFreeBSD is an hybrid system, for kernel-related issues we want to match the
build definitions used for FreeBSD, whereas for userland-related issues we want to
match the definitions used for other systems with Glibc.

The current modification adjusts the build system so that they can be distinguished,
and explicitly adds GNU/kFreeBSD to the build checks in which it belongs.

Fixes bug #16446.

OS Plugins' __init__ method takes two arguments: (self,process)

I was erroneously passing the session_dict as well as part of my PyCallable changes and that caused plugins to fail to work

been suitable for preparing a single IR function
for operation in the target.  However, using blocks
and lambdas creates other IR functions that also
need to be processed.

I have audited IRForTarget to make it process
multiple functions.  Where IRForTarget would add
new instructions at the beginning of the main
expression function, it now adds them on-demand
in the function where they are needed.  This is
enabled by a system of FunctionValueCaches, which
invoke a lambda to create or derive the values as
needed, or report the result of that lambda if it
has already been called for the given function.
