| * | Temporarily Revert "Add basic loop fusion pass." | Eric Christopher | 2019-04-17 | 1 | -37/+0 |
| | | | | | | | | | As it's causing some bot failures (and per request from kbarton). This reverts commit r358543/ab70da07286e618016e78247e4a24fcb84077fda. llvm-svn: 358546 | ||||
| * | [X86] Disable loop unrolling in loop vectorization pass when VF is 1. | Wei Mi | 2015-05-06 | 1 | -0/+37 |
| The patch disabled unrolling in loop vectorization pass when VF==1 on x86 architecture, by setting MaxInterleaveFactor to 1. Unrolling in loop vectorization pass may introduce the cost of overflow check, memory boundary check and extra prologue/epilogue code when regular unroller will unroll the loop another time. Disable it when VF==1 remove the unnecessary cost on x86. The same can be done for other platforms after verifying interleaving/memory bound checking to be not perf critical on those platforms.
