Stefan Pintilie	cb4f0c5c07	[PowerPC] Replace the Post RA List Scheduler with the Machine Scheduler ... We want to run the Machine Scheduler instead of the List Scheduler after RA. Checked with a performance run on a Power 9 machine with SPEC 2006 and while some benchmarks improved and others degraded the geomean was slightly improved with the Machine Scheduler.

Ehsan Amiri	a538b0f023	Adding -verify-machineinstrs option to PowerPC tests ... 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	2016-08-03 18:17:35 +00:00
Hal Finkel	79dbf5b562	[PowerPC] Cleanup cost model for unaligned vector loads/stores ... 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. llvm-svn: 246712	2015-09-02 21:03:28 +00:00
