* Temporarily Revert "Add basic loop fusion pass."Eric Christopher2019-04-171-43/+0
| | | | | | | | As it's causing some bot failures (and per request from kbarton). This reverts commit r358543/ab70da07286e618016e78247e4a24fcb84077fda. llvm-svn: 358546
* [InstCombine] Combine XOR and AES instructions on ARM/ARM64.Chad Rosier2018-05-241-0/+43
The ARM/ARM64 AESE and AESD instructions have a builtin XOR as the first step in the instruction. Therefore, if the AES key is zero and the AES data was previously XORed, it can be combined into a single instruction. Differential Revision: https://reviews.llvm.org/D47239 Patch by Michael Brase! llvm-svn: 333193
