Dan Gohman	40503396da	Eliminate more uses of llvm-as and llvm-dis. llvm-svn: 81290	2009-09-08 23:54:48 +00:00
Evan Cheng	9d339849ee	Teach branch folding pass about implicit_def instructions. Unfortunately we can't just eliminate them since register scavenger expects every register use to be defined. However, we can delete them when there are no intra-block uses. Carefully removing some implicit def's which enable more blocks to be optimized away. llvm-svn: 49461	2008-04-10 02:32:10 +00:00
