[PowerPC] Support __builtin_ppc_get_timebase GCC 4.8+ has a PowerPC-specific intrinsic, __builtin_ppc_get_timebase, to do what Clang's __builtin_readcyclecounter does. For compatibility with code that uses GCC's spelling (including glibc), support it as well. Partially fixes PR23681. llvm-svn: 246510

[CodeGenModule] Assume dso_local for -fpic -fno-semantic-interposition Summary: Clang -fpic defaults to -fno-semantic-interposition (GCC -fpic defaults to -fsemantic-interposition). Users need to specify -fsemantic-interposition to get semantic interposition behavior. Semantic interposition is currently a best-effort feature. There may still be some cases where it is not handled well.

[PowerPC] Add the support for __builtin_setrnd() in clang Summary: PowerPC64/PowerPC64le supports the builtin function __builtin_setrnd to set the floating point rounding mode. This function will use the least significant two bits of integer argument to set the floating point rounding mode. double __builtin_setrnd(int mode); The effective values for mode are: 0 - round to nearest 1 - round to zero 2 - round to +infinity 3 - round to -infinity Note that the mode argument will modulo 4, so if the int argument is greater than 3, it will only use the least significant two bits of the mode. Namely, builtin_setrnd(102)) is equal to builtin_setrnd(2). Reviewed By: jsji Differential Revision: https://reviews.llvm.org/D59403 llvm-svn: 357242
