* APFloat::roundToIntegral: Special values don't keep the exponent value up to ↵Benjamin Kramer2012-09-261-1/+1
| | | | | | | | date, don't rely on it. Add a couple of unit tests for special floats. Fixes 13929, found by MemorySanitizer. llvm-svn: 164698
* The assumption that /proc/self/exe always exists is incorrect.Sylvestre Ledru2012-09-261-4/+13
| | | | | | | | | | | For example, under a Linux chroot, /proc/ might not be mounted. Therefor, we test if this file exist. If it is the case, use it (the current behavior). Otherwise, we fall back to the detection used by *BSD. The issue has been reported initially on the Debian bug tracker: http://bugs.debian.org/674588 llvm-svn: 164676

* Rename ANDROIDEABI to Android.Logan Chien2012-09-021-2/+2
| | | | | | | | | | | | | Most of the code guarded with ANDROIDEABI are not ARM-specific, and having no relation with arm-eabi. Thus, it will be more natural to call this environment "Android" instead of "ANDROIDEABI". Note: We are not using ANDROID because several projects are using "-DANDROID" as the conditional compilation flag. llvm-svn: 163087
* Add some __builtin_expect magic to StringMap.Benjamin Kramer2012-08-291-4/+5
| | | | | | | | | Tombstones and full hash collisions are rare, mark the "empty" and "no collision" paths as likely. The bug in simplifycfg that prevented the hints from being picked during selfhost up was fixed recently :) llvm-svn: 162874

| | | | | | | | | Adds the vendor 'fsl' (used by Freescale SDK) to Triple. This will allow clang support for Freescale cross-compile configurations. Patch by Tobias von Koch. llvm-svn: 162726

* This patch fixes 8 out of 20 unexpected failures in "make check"Preston Gurd2012-07-181-0/+3
| | | | | | | | | | | | | | | when run on an Intel Atom processor. The failures have arisen due to changes elsewhere in the trunk over the past 8 weeks or so. These failures were not detected by the Atom buildbot because the CPU on the Atom buildbot was not being detected as an Atom CPU. The fix for this problem is in Host.cpp and X86Subtarget.cpp, but shall remain commented out until the current set of Atom test failures are fixed.
