Import llvm r187614 (git 44c8e34), for lldb's use:

Author: Daniel Malea <daniel.malea@intel.com>
Date: Thu Aug 1 21:18:16 2013 +0000

Fixed the Intel-syntax X86 disassembler to respect the (existing)
option for hexadecimal immediates, to match AT&T syntax. This also
brings a new option for C-vs-MASM-style hex.

MFC 261991:

Upgrade our copy of llvm/clang to 3.4 release. This version supports
all of the features in the current working draft of the upcoming C++
standard, provisionally named C++1y.

The code generator's performance is greatly increased, and the loop
auto-vectorizer is now enabled at -Os and -O2 in addition to -O3. The
PowerPC backend has made several major improvements to code generation
quality and compile time, and the X86, SPARC, ARM32, Aarch64 and SystemZ
backends have all seen major feature work.

Pull in r197521 from upstream clang trunk (by rdivacky):

Use the integrated assembler by default on FreeBSD/ppc and ppc64.

MFC 262611:

Pull in r196874 from upstream llvm trunk:

Fix a crash that occurs when PWD is invalid.

MCJIT needs to be able to run in hostile environments, even when PWD
is invalid. There's no need to crash MCJIT in this case.

The obvious fix is to simply leave MCContext's CompilationDir empty
when PWD can't be determined. This way, MCJIT clients,
and other clients that link with LLVM don't need a valid working directory.

If we do want to guarantee valid CompilationDir, that should be done
only for clients of getCompilationDir(). This is as simple as checking
for an empty string.

The only current use of getCompilationDir is EmitGenDwarfInfo, which
won't conceivably run with an invalid working dir. However, in the
purely hypothetically and untestable case that this happens, the
AT_comp_dir will be omitted from the compilation_unit DIE.

This should help fix assertions occurring with ports-mgmt/tinderbox,
when it is using jails, and sometimes invalidates clang's current
working directory.

Pull in r203007 from upstream clang trunk:

Don't produce an alias between destructors with different calling conventions.

Fixes pr19007.

(Please note that is an LLVM PR identifier, not a FreeBSD one.)

This should fix Firefox and/or libxul crashes (due to problems with
regparm/stdcall calling conventions) on i386.

MFC 263048:

Repair recognition of "CC" as an alias for the C++ compiler, since it
was silently broken by upstream for a Windows-specific use-case.

Apparently some versions of CMake still rely on this archaic feature...

MFC 263049:

Garbage collect the old way of adding the libstdc++ include directories
in clang's InitHeaderSearch.cpp. This has been superseded by David
Chisnall's commit in r255321.

Moreover, if libc++ is used, the libstdc++ include directories should
not be in the search path at all. These directories are now only used
if you pass -stdlib=libstdc++.

Upgrade our copy of llvm/clang to r155985, from upstream's release_31

MFC r235058:

Make sure a few new internal clang headers get installed, I missed these
in the last import. They are sometimes needed when you want to use
advanced instructions.

Also, add clang's internal stdalign.h header to ObsoleteFiles.inc, since
it is redundant: we already have a stdalign.h header in /usr/include.

Upgrade our Clang in base to r108428.

This commit merges the latest LLVM sources from the vendor space. It
also updates the build glue to match the new sources. Clang's version
number is changed to match LLVM's, which means /usr/include/clang/2.0
has been renamed to /usr/include/clang/2.8.
