| | | | | | | | | As it's causing some bot failures (and per request from kbarton). This reverts commit r358543/ab70da07286e618016e78247e4a24fcb84077fda. llvm-svn: 358546 | ||||
* | [LSR] canonicalize Prod*(1<<C) to Prod<<C | Jingyue Wu | 2015-06-24 | 1 | -0/+38 |
Summary: Because LSR happens at a late stage where mul of a power of 2 is typically canonicalized to shl, this canonicalization emits code that can be better CSE'ed. Test Plan: Transforms/LoopStrengthReduce/shl.ll shows how this change makes GVN more powerful. Fixes some existing tests due to this change.
