* Adding missing anchor to DATDeltaAlgorithm.David Blaikie2011-12-071-0/+3
| | | | llvm-svn: 146025
* Silence tsan false-positives (tsan can't track things which are only safe due toNick Lewycky2011-12-051-0/+3
| | | | | | | memory fences) in statistics registration, which works the same way that ManagedStatic registration does. llvm-svn: 145869

| | | | | | | | | | | | 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. llvm-svn: 145389
* Don't define these unless we plan to use them.Nick Lewycky2011-11-281-0/+2

* Add back a line I deleted by accident in r145141. Fixes uninitialized ↵Eli Friedman2011-11-281-0/+1
| | | | | | variable warnings and runtime failures. llvm-svn: 145256
* rename ENABLE_THREADS to LLVM_ENABLE_THREADSDylan Noblesmith2011-11-284-7/+7
| | | | | | | | | | | 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. llvm-svn: 145214
* Fix APFloat::convert so that it handles narrowing conversions correctly; itEli Friedman2011-11-261-49/+36
| | | | | | | | 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. llvm-svn: 145141
* Make ConstantRange::truncate a bit more efficient.Benjamin Kramer2011-11-241-4/+2

* Turn error recovery into an assert.Benjamin Kramer2011-11-221-6/+1
| | | | | | | 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. llvm-svn: 145059
* Move WEAK marking to the declaration.Nick Lewycky2011-11-151-6/+6
| | | | llvm-svn: 144603
* Fix linking for some users who already have tsan enabled code and are trying toNick Lewycky2011-11-151-6/+6
| | | | | | link it against llvm code, by making our definitions weak. "Some users." llvm-svn: 144596
* Add support for tsan annotations (thread sanitizer, a valgrind-based tool).Nick Lewycky2011-11-142-1/+18
| | | | | | | | | | | | 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: 144567
* Fix a typo.Benjamin Kramer2011-11-061-1/+1
| | | | llvm-svn: 143890

| | | | | | Process::Wait on Windows (mimicing POSIX behaviour). llvm-svn: 143876

* BlockFrequency: Use a smarter overflow check.Benjamin Kramer2011-10-271-4/+8
| | | | | | This trades one 64 bit div for one 64 bit mul and some arithmetic. llvm-svn: 143106

* Print branch probabilities as percentages.Benjamin Kramer2011-10-231-3/+3
| | | | | | 50% is much more readable than 5.000000e-01. llvm-svn: 142752

* Fix handling of the From parameter in StringRef::find.Benjamin Kramer2011-10-171-2/+5
| | | | | | Enable bounds checking to catch this kind of bug earlier. llvm-svn: 142247
* Let printf do the formatting instead aligning strings ourselves.Benjamin Kramer2011-10-162-17/+12
| | | | | | While at it, merge some format strings. llvm-svn: 142140
* remove the dead 'ShowLine' argument from SMDiagnostic.Chris Lattner2011-10-161-11/+8

* Make SMDiagnostic a little more sane. Instead of passing around ↵Chris Lattner2011-10-161-16/+22
| | | | | | | | note/warning/error as a string, pass it around as an enum. llvm-svn: 142107
* Enhance llvm::SourceMgr to support diagnostic ranges, the same way clang ↵Chris Lattner2011-10-161-21/+100
| | | | | | | | | | | | | | | 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. llvm-svn: 142106
* Add a bad char heuristic to StringRef::find.Benjamin Kramer2011-10-151-3/+26
| | | | | | | | | 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. llvm-svn: 142061

| | | | | | | | | | 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-". llvm-svn: 142055
* Fix for llvm::sys::getHostTriple on Windows. Instead of relying on the tripleChad Rosier2011-10-151-4/+36
