[PATCH, rs6000] 1/2 Add x86 MMX <mmintrin,h> intrinsics to GCC PPC64LE taget

2017-07-06 Thread Steven Munroe
These is the second major contribution of X86 intrinsic equivalent headers for PPC64LE. X86 MMX technology was the earlest integer SIMD and 64-bit scalar extension for IA32. MMX should have largely been replaced by now with X86_64 64-bit scalars and SSE 128-bit SIMD operation in modern
