Nick Lewycky 897a57ecda Silence tsan false-positives (tsan can't track things which are only safe due to
memory fences) in statistics registration, which works the same way that
ManagedStatic registration does.

NAKAMURA Takumi 64404a3b2c [Win32] Catch exceptions (eg. segfault) on waiting for invoked clang from the driver.
clang/lib/Driver/Driver.cpp: Don't pass through negative exit status, or parent would be confused.

llvm::sys::Program::Wait(): Suppose 0x8000XXXX and 0xC000XXXX as abnormal exit code and pass it as negative value.

Win32 Exception Handler: Exit with ExceptionCode on an unhandle exception.

Dylan Noblesmith efddf20126 rename ENABLE_THREADS to LLVM_ENABLE_THREADS
Now that it needs to be exported in a public header (Valgrind.h)
it should be prefixed to avoid collision with other projects.
Add it to llvm-config.h as well.

This'll require regenerating the configure script after this
commit, but I don't have the required autoconf version.

Eli Friedman a84ad7d0d0 Fix APFloat::convert so that it handles narrowing conversions correctly; it
was returning incorrect values in rare cases, and incorrectly marking
exact conversions as inexact in some more common cases. Fixes PR11406, and a
missed optimization in test/CodeGen/X86/fp-stack-O0.ll.

Benjamin Kramer f22623b78b Turn error recovery into an assert.
This was put in because in a certain version of DragonFlyBSD stat(2) lied about the
size of some files. This was fixed a long time ago so we can remove the workaround.

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
