* Revert "Temporarily Revert "Add basic loop fusion pass.""Eric Christopher2019-04-171-0/+48
| | | | | | | | The reversion apparently deleted the test/Transforms directory. Will be re-reverting again. llvm-svn: 358552
* Temporarily Revert "Add basic loop fusion pass."Eric Christopher2019-04-171-48/+0
| | | | | | | | As it's causing some bot failures (and per request from kbarton). This reverts commit r358543/ab70da07286e618016e78247e4a24fcb84077fda. llvm-svn: 358546
* [LoopUnroll] Clean up remarks for unroll remainderDavid Green2017-10-311-1/+24
| | | | | | | | | | | | | | | | The optimisation remarks for loop unrolling with an unrolled remainder looks something like: test.c:7:18: remark: completely unrolled loop with 3 iterations [-Rpass=loop-unroll] C[i] += A[i*N+j]; ^ test.c:6:9: remark: unrolled loop by a factor of 4 with run-time trip count [-Rpass=loop-unroll] for(int j = 0; j < N; j++) ^ This removes the first of the two messages. Differential revision: https://reviews.llvm.org/D38725 llvm-svn: 316986
* Fix vectorization remarks.Diego Novillo2014-04-291-0/+25
This patch changes the vectorization remarks to also inform when vectorization is possible but not beneficial. Added tests to exercise some loop remarks. llvm-svn: 207574
