We process autorelease counts when we exit functions, but if there's an
issue in a synthesized body the report will get dropped. Just skip the
processing for now and let it get handled when the caller gets around to
processing autoreleases.
(This is still suboptimal: objects autoreleased in the caller context
should never be warned about when exiting a callee context, synthesized
or not.)

Much of our diagnostic machinery is set up to assume that the report
end path location is valid. Moreover, the user may be quite confused
when something goes wrong in our BodyFarm-synthesized function bodies,
which may be simplified or modified from the real implementations.
Rather than try to make this all work somehow, just drop the report so
that we don't try to go on with an invalid source location.
Note that we still handle reports whose /paths/ go through invalid
locations, just not those that are reported in one.
We do have to be careful not to lose warnings because of this.
The impetus for this change was an autorelease being processed within
the synthesized body, and there may be other possible issues that are
worth reporting in some way. We'll take these as they come, however.

This unifies the unix and windows versions of FileManager::UniqueDirContainer
and FileManager::UniqueFileContainer by using UniqueID.
We cannot just replace "struct stat" with llvm::sys::fs::file_status, since we
want to be able to construct fake ones, and file_status has different members
on unix and windows.
What the patch does is:
* Record only the information that clang is actually using.
* Use llvm::sys::fs::status instead of stat and fstat.
* Use llvm::sys::fs::UniqueID
* Delete the old windows versions of UniqueDirContainer and
UniqueFileContainer since the "unix" one now works on windows too.

Function attributes are the future! So just query whether we want to realign the
stack directly from the function instead of through a random target options
structure.

This is actually an LLVM bug in the way it generates signatures for these
when soft float is enabled. For example, floor ends up having the signature
of int64(int64). The signature part is not the same as where the actual
parameter types are recorded, and those ARE of course int64(int64) when
soft float is enabled. (Yes, Mips16 hard float uses soft float but with
different runtime rounes but then has to interoperate with Mips32 using
normal floating point). This logic will eventually be moved to the
Mips16HardFloat pass so it's not worth sorting out these issues in LLVM
since nobody but Mips16 cares about these signatures, as far as I know,
and even I won't eventually either.

Without an ODR, the -flimit-debug-info debug info size optimization of
emitting declarations for fully defined types when only a declaration is
needed by the TU, is incorrect. Emit the full definition whenever it's
available in non-C++.

Also remove checking of llvm.dbg.sp since it is not used in generating dwarf.
Current state of Finder:
DebugInfoFinder tries to list all debug info MDNodes used in a module. To
list debug info MDNodes used by an instruction, DebugInfoFinder provides
processDeclare, processValue and processLocation to handle DbgDeclareInst,
DbgValueInst and DbgLoc attached to instructions. processModule will go
through all DICompileUnits in llvm.dbg.cu and list debug info MDNodes
used by the CUs.
TODO:
1> Finder has a list of CUs, SPs, Types, Scopes and global variables. We
need to add a list of variables that are used by DbgDeclareInst and
DbgValueInst.
2> MDString fields should be null or isa<MDString> and MDNode fields should be
null or isa<MDNode>. We currently use empty string or int 0 to represent null.
3> Go though Verify functions and make sure that they check field types.
4> Clean up existing testing cases to remove llvm.dbg.sp and make sure each
testing case has a llvm.dbg.cu.

We emit definitions with no members when a nested type is
referenced/required (GCC does the same, to be fair) but failed to attach
the template arguments in such a case.

(I'm not sure how to test this because the Driver will still accept
e.g. "-O4foo", but it goes in the catch-all -O option instead of -O4.)

This is another case where internalize hides a symbol that is needed by
a loadable module. I am currently investigating a proper fix but this patch
will get our buildbot to pass in the meantime. <rdar://problem/14578094>

mapping of source to assembly so that the same test script can be used

MSVC-specific, MSVCRT-specific, or Windows-specific. Because Clang can
also define _MSC_VER, and MSVCRT is not necessarily the only C runtime,
these macros should not be used interchangeably.
This patch divides all Windows-related bits into the aforementioned
categories. Two new macros are introduced:
- _LIBCPP_MSVC: Defined when compiling with MSVC. Detected using
_MSC_VER, excluding Clang.
- _LIBCPP_MSVCRT: Defined when using the Microsoft CRT. This is the default
when _WIN32 is defined.
This leaves _WIN32 for code using the Windows API.
This also corrects the spelling of _LIBCP_HAS_IS_BASE_OF to _LIBCPP_HAS_IS_BASE_OF.
Nico, please prepare a patch for CREDITS.TXT, thanks.

This adds a new parameter, --skip-category, that can be used to list
categories that should be skipped. For example, to run all tests except for
Objective-C ones, one can now write:
./dotest.py --skip-category objc [...]

Before:
template <bool B, bool C>
class A {
static_assert(B &&C, "Something is wrong");
};
After:
template <bool B, bool C>
class A {
static_assert(B && C, "Something is wrong");
};
(Note the spacing around '&&'). Also change the identifier table to always
understand all C++11 keywords (which seems like the right thing to do).

* Added R600_Reg64 class
* Added T#Index#.XY registers definition
* Added v2i32 register reads from parameter and global space
* Added f32 and i32 elements extraction from v2f32 and v2i32
* Added v2i32 -> v2f32 conversions
Tom Stellard:
- Mark vec2 operations as expand. The addition of a vec2 register
class made them all legal.

We needed a way to tell LSan to invoke leak checking only if __do_leak_check()
is called explicitly. This can now be achieved by setting
leak_check_at_exit=false.
