Dan Gohman	40503396da	Eliminate more uses of llvm-as and llvm-dis. ... llvm-svn: 81290	2009-09-08 23:54:48 +00:00
Chris Lattner	e819cfbc71	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
Dan Gohman	ac33a9061d	Add an x86 peep that narrows TEST instructions to forms that use ... a smaller encoding. These kinds of patterns are very frequent in sqlite3, for example. llvm-svn: 79439	2009-08-19 18:16:17 +00:00
