Eric Christopher	71d1cca7ef	Temporarily Revert "Add basic loop fusion pass." ... As it's causing some bot failures (and per request from kbarton). This reverts commit r358543/ab70da07286e618016e78247e4a24fcb84077fda. llvm-svn: 358546	2019-04-17 02:12:23 +00:00
Jingyue Wu	35a6e27706	[InstCombine] call SimplifyICmpInst with correct context ... Summary: Fixes PR23809. Without passing the context to SimplifyICmpInst, we would use the assume to prove that the condition feeding the assume is trivially true (see isValidAssumeForContext in ValueTracking.cpp), causing the removal of the assume which may be useful for later optimizations.
