Chris Lattner 55149d7835 Fix a bug in the local spiller, where we could take code like this: ... store r12 -> [ss#2] R3 = load [ss#1] use R3 R3 = load [ss#2] R4 = load [ss#1] and turn it into this code: store R12 -> [ss#2] R3 = load [ss#1] use R3 R3 = R12 R4 = R3 <- oops! The problem was that promoting R3 = load[ss#2] to a copy missed the fact that the instruction invalidated R3 at that point. llvm-svn: 23638		2005-10-05 18:30:19 +00:00
