Up until Power9, the performance profile for rlwinm., rldicl. and andi. looked more or less equivalent. However with Power9, the rotates are still 2-way cracked whereas the and-immediate is not. This patch just ensures that we don't emit record-form rotates when an andi. is adequate. As first pointed out by Carrot in https://bugs.llvm.org/show_bug.cgi?id=30833 (this patch is a fix for that PR). Differential Revision: https://reviews.llvm.org/D43977 llvm-svn: 326736 |
