Dan Gohman	58b0470592	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	997bbc54d6	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

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.
