* [PowerPC] Do not emit record-form rotates when record-form andi/andis sufficesNemanja Ivanovic2018-09-181-0/+61
| | | | | | | | | | | | This is a follow-up to the previous patch that eliminated some of the rotates. With this addition, we will also emit the record-form andis. This patch increases the number of record-form rotates we eliminate by more than 70%. Differential revision: https://reviews.llvm.org/D44897 llvm-svn: 342478
* [PowerPC] Do not emit record-form rotates when record-form andi sufficesNemanja Ivanovic2018-03-051-0/+42
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
