* 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
* PPC: Teach FMA mutate to respect register classes.Kyle Butt2015-12-101-0/+89
This was causing bad code gen and assembly that won't assemble, as mixed altivec and vsx code would end up with a vsx high register assigned to an altivec instruction, which won't work. Constraining the classes allows the optimization to proceed. llvm-svn: 255299
