Summary:
This switches the decision as to whether or not to lldb-server should
be built to check the same flag that was added that controls whether
or not it is added as a dependency to the 'lldb' target.
It also sets that flag on FreeBSD to maintain parity with the existing
build configuration / situation on FreeBSD.

We used to sort the symbols at the very end, but we need to know the order
earlier so that we can create reference to them in the dynamic relocations.
Thanks to Igor Kudrin for pointing out the problem.

Character with ASCII code 0 is incorrectly treated by LLDB as the end of
RSP packet. The left of the debugger server output is silently ignored.

This information is implicitly available through the multi-dimensionality of
memory accesses. This reduces compile time for 3mm from 430ms to 400ms and
should generally benefit compile time for cases where the assumed context
is complex.

If the GEP instructions give us enough insights, model scalar accesses as
multi-dimensional (and generate the relevant run-time checks to ensure
correctness). This will allow us to simplify the dependence computation in
a subsequent commit.

getLandingPadSuccessor assumes that each invoke can have at most one EH
pad successor, but WinEH invokes can have more than one. Two out of
three callers of getLandingPadSuccessor don't use the returned
landingpad, so we can make them use this simple predicate instead.
Eventually we'll have to circle back and fix SplitKit.cpp so that
register allocation works. Baby steps.

Mingw generally wraps an old copy of msvcrt.dll which has these

it.

This fixes -data-info-line and -symbol-list-lines to parse the filename
and line correctly when line entries don't have the optional column
number and the filename contains a Windows drive letter. It also fixes
-symbol-list-lines when code from header files is generated.

Temporarily revert to fix some buildbot issues. One is a minor issue
with a variable unused in NDEBUG mode. More concerning are some test
failures on win7 that I need to dig into.
This reverts commit 4e66a74543459832cfd571db42b4543580ae1d1d.

Summary:
This assembler directive is used in O32 PIC to restore the current function's $gp after executing JAL's. The $gp is first stored on the stack at a user-specified offset.
It has the following format: ".cprestore 8" (where 8 is the offset).
This fixes llvm.org/PR20967.

llvm-svn: 247897
Summary:
Support for including the function bitcode indices in the Value Symbol
Table. This requires writing the VST after the function blocks, which in
turn requires a new VST forward declaration record encoding the offset of
the full VST (which is backpatched to contain the offset after the VST
is written).
This patch also enables the lazy function reader to use the new function
indices out of the VST. This support will be used by ThinLTO as well, which
will be in a follow on patch. Backwards compatibility with older bitcode
files is maintained.
A new test is also included.
The bitcode format (used for the lazy reader as well as the upcoming
ThinLTO patches) came out of discussions with Duncan and others and is
described here:

Scripts are installed in same location as clang-fromat ones, so I think will be good idea to not create dedicated directory.
I checked this patch on my own build on RHEL 6.
Please check it in if it's OK, because I don't have SVN write access.
I think will be good idea to backport this patch to 3.7 release branch.
Probably same should be done for configure build.

This adds enough machinery to support reading simple GCC AutoFDO
profiles. It now supports reading flat profiles (no function calls).
Subsequent patches will add support for:
- Inlined calls (in particular, the inline call stack is not traversed
to accumulate samples).
- Working sets and modules. These are used mostly for GCC's LIPO
optimizations, so they're not needed in LLVM atm. I'm not sure that
we will ever need them. For now, I've if0'd around the calls.
The patch also adds support in GCOV.h for gcov version V704 (generated
by GCC's profile conversion tool).

Basically the concept of "liveness" is for sections (or chunks in LLD
terminology) and not for symbols. Symbols are always available or live,
or otherwise it indicates a link failure.
Previously, we had isLive() and markLive() methods for DefinedSymbol.
They are confusing methods. What they actually did is to act as a proxy
to backing section chunks. We can simplify eliminate these methods
and call section chunk's methods directly.
