platforms and called in lldb.cpp while it is built only on some, excluding OSX.
There is no reason to not build it then by default on all platforms.
This fixes build on OSX using llvm configure & make scripts.

We cannot use "GetMaxU64Bitfield" for non-power-of-two sizes, so just use
the same code that handles N > 8 for these.

- searches frames beginning from the current frame, stops when an equivalent context is found
- not using GetStackFrameCount() for performance reasons
- fixes TestInlineStepping (clang/gcc buildbots)
llvm-svn: 190868
- ProcessMonitor::[Do|Serve]Operation no longer depend on file descriptors!
- removed unused member functions CloseFD and EnableIPC
- add semaphores to signal when an Operation is ready to be processed/complete.
This commit fixes a bug that was identified under stress-testing (i.e. build
LLVM while running tests) that led to LLDB becoming unresponsive because the
read/write operations on file descriptors in ProcessMonitor were not checked.
Other test runner improvement/convenience:
- pickup environment variables LLDB_LINUX_LOG and LLDB_LINUX_LOG_OPTIONS to
enable (Linux) logging when running the test suite. Example usage:
$ LLDB_LINUX_LOG="mylog.txt" LLDB_LINUX_LOG_OPTIONS="process thread" python dotest.py
llvm-svn: 190820
for the frame is one past the address range of the calling function.
- Lowers the fix from RegisterContextLLDB for use with disassembly
- Fixes one of three issues in the disassembly test in TestInferiorAssert.py
Also adds documentation that explains the resolution depths and interface.
Note: This change affects the resolution scope for eSymbolContextFunction
without impacting the performance of eSymbolContextSymbol.
Thanks to Matt Kopec for his review.

Fixed an issue with the lldb/test/lang/cpp/virtual test case had a virtual class that had a DW_TAG_inheritance child that was virtual and had a DW_AT_data_member_location of:
DW_AT_data_member_location( DW_OP_dup, DW_OP_deref, DW_OP_constu(0x00000018), DW_OP_minus, DW_OP_deref, DW_OP_plus )
We failed to evaluate this and then we were passing the incorrect offset back to clang and clang would crash. The AST external source has a function named LayoutRecordType which allows us to supply the virtual base class offsets, but that really doesn't make sense to do as clang will lay them out correctly. So we must ignore virtual base classes when doing layout.

and a mach kernel in all the pages of the core file. If it finds
a user-process dyld binary, assume this is a user process that had
a copy of the mach kernel in memory when it crashed (e.g. lldb doing
kernel debugging) even though we found the kernel binary first.
Also, change the error messages about sections extending past the end
of the file to be warnings and make the messages sound less severe.
Most user process core files have one section that isn't included in
the file and there's no reason to worry people about that.

1. existing breakpoints weren't being re-resolved after the sections of a library were loaded (ie. through dlopen).
2. loaded sections weren't being removed after a shared library had been unloaded.

with prefer_file_cache == false. This is what we want to do when
the user is doing a disassemble command -- show the actual memory
contents in case the memory has been corrupted or something -- but
when we're profiling functions for stepping or unwinding
(ThreadPlanStepRange::GetInstructionsForAddress,
UnwindAssemblyInstEmulation::GetNonCallSiteUnwindP) we can read
__TEXT instructions directly out of the file, if it exists.

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)

communication, connection, host, module, mmap, os. Add those. Also
sort the entries so they come in alphabetical order, to make it a
little easier to scan down the list for a specific channel.

SVN r189964 provided a sample Python script to inspect unordered(multi){set|map} with synthetic children, contribued by Jared Grubb
This checkin converts that sample script to a C++ provider built into LLDB
A test case is also provided

setting of the environment variable COMMAND_MODE. Changed the Platform::GetResumeCountForShell
to Platform::GetResumeCountForLaunchInfo, and check both the shell and in the case of
/bin/sh the environment as well.

that /bin/sh re-exec's itself to /bin/bash, so it needs one more resume when you
are using it as the shell than /bin/bash did or you will stop at the start of your
program, rather than running it.
So I added a Platform API to get the number of resumes needed when launching with
a particular shell, and set the right values for Mac OS X.

"coalesce the line ranges for a file & line breakpoint to the first range in each block". We were still setting a silly number
of independent breakpoints sometimes, and until we get a compiler that emits trustworthy is_stmt flags in the line table, we
need to do something to reduce the noise.

From Jim's post on the lldb-dev mailing list:
This code is there as a backstop for when the unwinder drops a frame at
the beginning of new function/trampoline or whatever.
In the (older_ctx_is_equivalent == false) case we will see if we are at
a trampoline function that somebody knows how to get out of, and
otherwise we will stop.
