* [Power9] Add exploitation of non-permuting memory opsNemanja Ivanovic2016-09-221-1/+12
| | | | | | | | | | | | This patch corresponds to review: https://reviews.llvm.org/D19825 The new lxvx/stxvx instructions do not require the swaps to line the elements up correctly. In order to select them over the lxvd2x/lxvw4x instructions which require swaps, the patterns for the old instruction have a predicate that ensures they won't be selected on Power9 and newer CPUs. llvm-svn: 282143
* Adding -verify-machineinstrs option to PowerPC testsEhsan Amiri2016-08-031-1/+1
| | | | | | | | | | | Currently we have a number of tests that fail with -verify-machineinstrs. To detect this cases earlier we add the option to the testcases with the exception of tests that will currently fail with this option. PR 27456 keeps track of this failures. No code review, as discussed with Hal Finkel. llvm-svn: 277624
