Chris Lattner c87c50a39c Enhance SRoA to promote allocas that are used by selects in some ... common cases. This triggers a surprising number of times in SPEC2K6 because min/max idioms end up doing this. For example, code from the STL ends up looking like this to SRoA: %202 = load i64* %__old_size, align 8, !tbaa !3 %203 = load i64* %__old_size, align 8, !tbaa !3 %204 = load i64* %__n, align 8, !tbaa !3 %205 = icmp ult i64 %203, %204 %storemerge.i = select i1 %205, i64* %__n, i64* %__old_size %206 = load i64* %storemerge.i, align 8, !tbaa !3 We can now promote both the __n and the __old_size allocas. This addresses another chunk of rdar://7339113, poor codegen on stringswitch. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@124088 91177308-0d34-0410-b5e6-96231b3b80d8		2011-01-23 22:04:55 +00:00
