Dan Gohman	df2896d609	Eliminate more uses of llvm-as and llvm-dis. ... llvm-svn: 81290	2009-09-08 23:54:48 +00:00
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
Evan Cheng	9b27f3ec42	Teach LSR to optimize more loop exit compares, i.e. change them to use postinc iv value. Previously LSR would only optimize those which are in the loop latch block. However, if LSR can prove it is safe (and profitable), it's now possible to change those not in the latch blocks to use postinc values. ... Also, if the compare is the only use, LSR would place the iv increment instruction before the compare instead in the latch. llvm-svn: 71485	2009-05-11 22:33:01 +00:00
