Chris Lattner	4ec0b670d5	fix PR6533 by updating the br(xor) code to remember the case when it looked past a trunc. llvm-svn: 98203	2010-03-10 23:46:44 +00:00
Chris Lattner	55e81eb49f	Fix PR6497, a bug where we'd fold a load into an addc node which has a flag. That flag in turn was used by an already-selected adde which turned into an ADC32ri8 which used a selected load which was chained to the load we folded. This flag use caused us to form a cycle. Fix this by not ignoring chains in IsLegalToFold even in cases where the isel thinks it can. llvm-svn: 97791	2010-03-05 06:19:13 +00:00
