* APFloat cleanup: Remove now unused "arithmeticOK" logic.Ulrich Weigand2012-10-291-42/+8

* APFloat cleanup: Remove now unused fields "sign2" and "exponent2".Ulrich Weigand2012-10-291-21/+9

* Implement arithmetic on APFloat with PPCDoubleDouble semantics byUlrich Weigand2012-10-291-76/+65
| | | | | | | | | | | | treating it as if it were an IEEE floating-point type with 106-bit mantissa. This makes compile-time arithmetic on "long double" for PowerPC in clang (in particular parsing of floating point constants) work, and fixes all "long double" related failures in the test suite. llvm-svn: 166951
* Don't explicitly require RTTI and EH.Joerg Sonnenberger2012-10-262-9/+0
| | | | llvm-svn: 166772
* Support: Don't remove special files on signals.Daniel Dunbar2012-10-171-9/+21
| | | | | | | - Similar to Path::eraseFromDisk(), we don't want LLVM to remove things like /dev/null, even if it has the permission. llvm-svn: 166105

* Revert r165652: "Remove unnecessary RTTI from the build."Sean Silva2012-10-102-0/+5
| | | | | | ... Apparently the RTTI is still necessary for some reason. llvm-svn: 165654

* Support for generating ELF objects on Windows.Andrew Kaylor2012-10-021-0/+2
| | | | | | This adds 'elf' as a recognized target triple environment value and overrides the default generated object format on Windows platforms if that value is present. This patch also enables MCJIT tests on Windows using the new environment value. llvm-svn: 165030

* 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

| | | | | | | | | | * wrap code blocks in \code ... \endcode; * refer to parameter names in paragraphs correctly (\arg is not what most people want -- it starts a new paragraph); * use \param instead of \arg to document parameters in order to be consistent with the rest of the codebase. llvm-svn: 163902

* 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
