* Temporarily Revert "Add basic loop fusion pass."Eric Christopher2019-04-171-74/+0
| | | | | | | | As it's causing some bot failures (and per request from kbarton). This reverts commit r358543/ab70da07286e618016e78247e4a24fcb84077fda. llvm-svn: 358546
* The cost of splitting a large vector instruction is not being taken into ↵Graham Yiu2017-10-191-0/+74
account by the getUserCost function. This was leading to some loops being over unrolled. The cost of a vector instruction is now being multiplied by the cost of the type legalization. This will return a more accurate cost. Committing on behalf on Brad Nemanich (brad.nemanich@ibm.com) Differential Revision: https://reviews.llvm.org/D38961 llvm-svn: 316174
