Zi Xuan Wu	9479f6d72e	[PowerPC] Fix assert from machine verify pass that unmatched register class about fcmp selection in fast-isel ... Bad machine code: Illegal virtual register for instruction function: TestULE basic block: %bb.0 entry (0x1000a39b158) instruction: %2:crrc = FCMPUD %1:vsfrc, %3:f8rc operand 1: %1:vsfrc Fix assert about missing match between fcmp instruction and register class. We should use vsx related cmp instruction xvcmpudp instead of fcmpu when vsx is opened. add -verifymachineinstrs option into related test cases to enable the verify pass.

Bill Seurer	1baeeb029b	[PowerPC]Update Power VSX test cases to also test fast-isel ... Update of some of the VSX test cases for Power to check fast-isel codegen as well as the regular codegen. http://reviews.llvm.org/D6357 llvm-svn: 223509	2014-12-05 20:32:05 +00:00
Hal Finkel	c6fc9b8960	[PowerPC] Use a small cleanup pass to remove VSX self copies ... As explained in r204976, because of how the allocation of VSX registers interacts with the call-lowering code, we sometimes end up generating self VSX copies. Specifically, things like this: %VSL2<def> = COPY %F2, %VSL2<imp-use,kill> (where %F2 is really a sub-register of %VSL2, and so this copy is a nop) This adds a small cleanup pass to remove these prior to post-RA scheduling. llvm-svn: 204980	2014-03-27 23:12:31 +00:00
