Hal Finkel 0a3e33b633 Improve ext/trunc patterns on PPC64. ... The PPC64 backend had patterns for i32 <-> i64 extensions and truncations that would leave self-moves in the final assembly. Replacing those patterns with ones based on the SUBREG builtins yields better-looking code. Thanks to Jakob and Owen for their suggestions in this matter. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@158283 91177308-0d34-0410-b5e6-96231b3b80d8		2012-06-09 22:10:19 +00:00
