Dan Gohman	40561dd0ba	When checking whether the special handling for an addrec increment which ... doesn't dominate the header is needed, don't check whether the increment expression has computable loop evolution. While the operands of an addrec are required to be loop-invariant, they're not required to dominate any part of the loop. This fixes PR6914. llvm-svn: 102389	2010-04-26 21:46:36 +00:00
Dan Gohman	38949c2f1f	Fix LSR to tolerate cases where ScalarEvolution initially ... misses an opportunity to fold add operands, but folds them after LSR has separated them out. This fixes rdar://7886751. llvm-svn: 102157	2010-04-23 01:55:05 +00:00
