Re: [PATCH], Add power9 support to GCC, patch #8 (add integer multiply/add)

This patch adds support for the MADDLD instruciton, which is a fused multiply/add instruction for integers. At this time, it is for 64-bit multiplies only. Eventually, we will restructure 128-bit multiply so that we can use the 64x64 + 64 high bit varients. I have bootstrapped a compiler with th
