Chris Lattner f0ef4b4391 Fix a nasty problem on two-address machines in the following situation: ... store EAX -> [ss#0] [ss#0] += 1 ... use(EAX) In this case, it is not valid to rewrite this as: store EAX -> [ss#0] EAX += 1 store EAX -> [ss#0] ;;; this would also delete the store above ... use(EAX) ... because EAX is not a dead at that point. Keep track of which registers we are allowed to clobber, and which ones we aren't, and don't clobber the ones we're not supposed to. :) This should resolve the issues on X86 last night. llvm-svn: 25948		2006-02-03 23:28:46 +00:00
