Hi, May I get review for a webrev to fix SLP patterns that use PPC64 VSX instructions? We found that SLP patterns added by JDK-8208171 [1] use incorrect data type, so the patterns have never been used. Further, the pattern for filling -1.0 is confused with the operation for filling -1L. This webrev fixes the pattern to fill an array with 0 to use 0.0d instead of 0d, and removes the pattern to will with -1 because the bit pattern of -1.0d is not easy to generate using a single VSX instruction. It's should be better to load the literal from TOC and use general repl2D_reg_Ex pattern. I also fixed some comments in "format %{ ... %}" to show correct matching types.
