URL: https://github.com/llvm/llvm-project/commit/2abc33683b2b702c00c366d56c6285fda6d1e436 DIFF: https://github.com/llvm/llvm-project/commit/2abc33683b2b702c00c366d56c6285fda6d1e436.diff LOG: [PowerPC] [Clang] Define macros to identify quad-fp semantics We have option -mabi=ieeelongdouble to set current long double to IEEEquad semantics. Like what GCC does, we need to define __LONG_DOUBLE_IEEE128__ macro in this case, and __LONG_DOUBLE_IBM128__ if using PPCDoubleDouble.
