* Change all checks regarding the presence of any SSE level to alwaysBruno Cardoso Lopes2011-09-15
| | | | | | | | | | take into consideration the presence of AVX. This change, together with the SSEDomainFix enabled for AVX, makes AVX codegen to always (hopefully) emit the same code as SSE for 128-bit vector ops. I don't have a testcase for this, but AVX now beats SSE in performance for 128-bit ops in the majority of programas in the llvm testsuite git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@139817 91177308-0d34-0410-b5e6-96231b3b80d8

* Trace through sibling PHIs in bulk.Jakob Stoklund Olesen2011-09-15
| | | | | | | | | | | | | | | When traceSiblingValue() encounters a PHI-def value created by live range splitting, don't look at all the predecessor blocks. That can be very expensive in a complicated CFG. Instead, consider that all the non-PHI defs jointly dominate all the PHI-defs. Tracing directly to all the non-PHI defs is much faster that zipping around in the CFG when there are many PHIs with many predecessors. This significantly improves compile time for indirectbr interpreters. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@139797 91177308-0d34-0410-b5e6-96231b3b80d8

* Use getPrevSlot() instead of getPrevIndex().Jakob Stoklund Olesen2011-09-15
| | | | | | | | The getPrevIndex() function moves to the same slot in the previous instruction. For getVNInfoBefore(), we just need the previous slot in the same instruction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@139793 91177308-0d34-0410-b5e6-96231b3b80d8
* Speed up LiveIntervals::shrinkToUse with some caching.Jakob Stoklund Olesen2011-09-15
| | | | | | | | | | | | | Blocks with multiple PHI successors only need to go on the worklist once. Use a SmallPtrSet to track the live-out blocks that have already been handled. This is a lot faster than the two live range check we would otherwise do. Also stop recomputing hasPHIKill flags. Like RenumberValues(), it is conservatively correct to leave them in, and they are not used for anything important. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@139792 91177308-0d34-0410-b5e6-96231b3b80d8
