* Temporarily Revert "Add basic loop fusion pass."Eric Christopher2019-04-171-140/+0
| | | | | | | | As it's causing some bot failures (and per request from kbarton). This reverts commit r358543/ab70da07286e618016e78247e4a24fcb84077fda. llvm-svn: 358546
* [ppc] Correctly compute the cost of loading 32/64 bit memory into VSRGuozhi Wei2016-12-031-0/+140
VSX has instructions lxsiwax/lxsdx that can load 32/64 bit value into VSX register cheaply. That patch makes it known to memory cost model, so the vectorization of the test case in pr30990 is beneficial. Differential Revision: https://reviews.llvm.org/D26713 llvm-svn: 288560
