| | | | | | | | | | test/Regression/Assembler/2004-02-01-NegativeZero.llx. Basically we store floating point values as their integral components, instead of relying on the semantics of floating point < to differentiate between values. This is likely to make the map search be faster anyway. llvm-svn: 11064

* 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. llvm-svn: 11053
