* Temporarily Revert "Add basic loop fusion pass."Eric Christopher2019-04-171-701/+0
| | | | | | | | As it's causing some bot failures (and per request from kbarton). This reverts commit r358543/ab70da07286e618016e78247e4a24fcb84077fda. llvm-svn: 358546
* [SLPVectorizer] reorderInputsAccordingToOpcode - remove non-Instruction ↵Simon Pilgrim2019-03-251-17/+17
| | | | | | | | | | | | | | canonicalization Remove attempts to commute non-Instructions to the LHS - the codegen changes appear to rely on chance more than anything else and also have a tendency to fight existing instcombine canonicalization which moves constants to the RHS of commutable binary ops. This is prep work towards: (a) reusing reorderInputsAccordingToOpcode for alt-shuffles and removing the similar reorderAltShuffleOperands (b) improving reordering to optimized cases with commutable and non-commutable instructions to still find splat/consecutive ops.
