Nick Lewycky b2489b7484 Fix linking for some users who already have tsan enabled code and are trying to
link it against llvm code, by making our definitions weak. "Some users."

Nick Lewycky fe856110aa Add support for tsan annotations (thread sanitizer, a valgrind-based tool).
These annotations are disabled entirely when either ENABLE_THREADS is off, or
building a release build. When enabled, they add calls to functions with no
statements to ManagedStatic's getters.

Use these annotations to inform tsan that the race used inside ManagedStatic
initialization is actually benign. Thanks to Kostya Serebryany for helping
write this patch!

llvm-svn: 142108
2011-10-16 05:47:55 +00:00
Chris Lattner 03b80a4027 Make SMDiagnostic a little more sane. Instead of passing around note/warning/error as a
string, pass it around as an enum.

Chris Lattner a3a0681083 Enhance llvm::SourceMgr to support diagnostic ranges, the same way clang does. Enhance
the X86 asmparser to produce ranges in the one case that was annoying me, for example:

test.s:10:15: error: invalid operand for instruction
movl 0(%rax), 0(%edx)
              ^~~~~~~

It should be straight-forward to enhance filecheck, tblgen, and/or the .ll parser to use 
ranges where appropriate if someone is interested.

Benjamin Kramer 4d681d7dc4 Add a bad char heuristic to StringRef::find.
Based on Horspool's simplified version of Boyer-Moore. We use a constant-sized table of
uint8_ts to keep cache thrashing low, needles bigger than 255 bytes are uncommon anyways.

The worst case is still O(n*m) but we do a lot better on the average case now.

NAKAMURA Takumi ea97a05fc5 Revert r142046, "Fix for llvm::sys::getHostTriple on Windows. Instead of relying on the triple"
It extremely breaks builds when optimization is enabled. Twine should not hold temporary objects.

By the way, I might feel sad if I saw "i786-" "i1586-" or "iF86-".

Chad Rosier 559b8f2ae9 Fix for llvm::sys::getHostTriple on Windows. Instead of relying on the triple

Bruno Cardoso Lopes cc6659b2ae The Mips specific function for instruction cache invalidation cannot be
compiled on mips32r1 processors because it uses synci and rdhwr instructions
which are supported only on mips32r2, so I replaced this function with the
call to function cacheflush which works for both mips32r1 and mips32r2.

Bob Wilson 49621cb209 Remove the hack to check UNAME_RELEASE when identifying the Darwin version.
This was only needed to locate llvm-gcc's installation directory when clang
falls back to run llvm-gcc for i386 kexts.  As of clang svn r140187, we're
now just searching paths with several different Darwin versions on either
side of the current version, so this is no longer needed.
