*	[SCEV] Don't create SCEV expressions that break LCSSA	Sanjoy Das	2015-10-31	1	-0/+24
\| \| \| \| \| \| \| \| \| \| \| \| \|	Prevent `createNodeFromSelectLikePHI` from creating SCEV expressions that break LCSSA. A better fix for the same issue is to teach SCEVExpander to not break LCSSA by inserting PHI nodes at appropriate places. That's planned for the future. Fixes PR25360. llvm-svn: 251756
*	[SCEV] Recognize simple br-phi patterns	Sanjoy Das	2015-10-02	1	-0/+104
	Summary: Teach SCEV to match patterns like ``` br %cond, label %left, label %right left: br label %merge right: br label %merge merge: V = phi [ %x, %left ], [ %y, %right ] ``` as "select %cond, %x, %y". Before this SCEV would match PHI nodes exclusively to add recurrences. This addresses PR25005.
