Chris Lattner	e819cfbc71	change selectiondag to add the sign extended versions of immediate operands ... to instructions instead of zero extended ones.

Dan Gohman	e99f98262c	Permit ChangeCompareStride to rewrite a comparison when the factor ... between the comparison's iv stride and the candidate stride is exactly -1. llvm-svn: 70244	2009-04-27 20:35:32 +00:00
