* Now that tailduplication does not bork SSA form, run mem2reg earlier in gccas.Chris Lattner2004-02-011-2/+4
| | | | | | | | | | | This tremendously improves the code generated by the LLVM optimizer, primarily by making the inliner more aggressive. For example, it improves the stepanov benchmark from 55.56 mega-additions/sec to 98.04 Ma/s. It also improves the oopack/iterator benchmark from 338.3MFLOPS/s to 1103.4MFLOPS/s. Less noteworthy, it improves oopack/matrix from 573 -> 641 MFLOPS/s. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11053 91177308-0d34-0410-b5e6-96231b3b80d8
