Chris Lattner eddfe437c7 Now that tailduplication does not bork SSA form, run mem2reg earlier in gccas. 
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.

Chris Lattner ed9b12c31a Disable tail duplication in any "hard" cases, where it might break SSA form.

any test cases :-)

FirstVirtualRegister

llvm-svn: 11031
 2004-01-31 19:57:11 +00:00
Alkis Evlogimenos cdf48ab294 Optimize liveAt() and overlaps(). We now use a binary search instead 
of a linear search to find the first range for comparisons. This cuts
down the linear scan register allocator running time by a factor of 3
in 254.perlbmk and by a factor of 2.2 in 176.gcc.

Chris Lattner 4710add9dd Add (currently disabled) support to the instruction selector to only insert 
FP_REG_KILL instructions at the end of blocks involved with critical edges.

Fix a bug where FP_REG_KILL instructions weren't inserted in fall through
unconditional branches.  Perhaps this will fix some linscan problems?
