1. Actually increment the Statistic for the GV elim optzn 2. When resolving undef branches, only resolve branches in executable blocks, avoiding marking a bunch of completely dead blocks live. This has a big impact on the quality of the generated code. With this patch, we positively rip up vortex, compiling Ut_MoveBytes to a single memcpy call. In vortex we get this: 12 ipsccp - Number of globals found to be constant 986 ipsccp - Number of arguments constant propagated 1378 ipsccp - Number of basic blocks unreachable 8919 ipsccp - Number of instructions removed git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@18796 91177308-0d34-0410-b5e6-96231b3b80d8 |
