Hal Finkel 5d195fd587 Check for all known bits on ret in InstCombine ... From a combination of @llvm.assume calls (and perhaps through other means, such as range metadata), it is possible that all bits of a return value might be known. Previously, InstCombine did not check for this (which is understandable given assumptions of constant propagation), but means that we'd miss simple cases where assumptions are involved. llvm-svn: 217346		2014-09-07 21:28:34 +00:00
