Chris Lattner	0b34068b2b	change selectiondag to add the sign extended versions of immediate operands ... to instructions instead of zero extended ones. This makes the asmprinter print signed values more consistently. This apparently only really affects the X86 backend. llvm-svn: 81265	2009-09-08 23:05:44 +00:00
Eli Friedman	ccdfdbfc99	Followup to r60283: optimize arbitrary width signed divisions as well ... as unsigned divisions. Same caveats as before. llvm-svn: 60284	2008-11-30 06:35:39 +00:00
