2016-08-03Adding -verify-machineinstrs option to PowerPC testsEhsan Amiri
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@277624 91177308-0d34-0410-b5e6-96231b3b80d8
2015-09-02[PowerPC] Cleanup cost model for unaligned vector loads/storesHal Finkel
I'm adding a regression test to better cover code generation for unaligned vector loads and stores, but there's no functional change to the code generation here. There is an improvement to the cost model for unaligned vector loads and stores, mostly for QPX (for which we were not previously accounting for the permutation-based loads), and the cost model implementation is cleaner. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@246712 91177308-0d34-0410-b5e6-96231b3b80d8
