* Fix APFloat::convert so that it handles narrowing conversions correctly; itEli Friedman2011-11-26
| | | | | | | | | | was returning incorrect values in rare cases, and incorrectly marking exact conversions as inexact in some more common cases.

* Add support for tsan annotations (thread sanitizer, a valgrind-based tool).Nick Lewycky2011-11-14
| | | | | | | | | | | | | 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.

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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142106 91177308-0d34-0410-b5e6-96231b3b80d8
* Add a bad char heuristic to StringRef::find.Benjamin Kramer2011-10-15
| | | | | | | | | 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.

| | | | | | | | | | It is an endian-aware helper that can read data from a StringRef. It will come in handy for DWARF parsing.
