* Temporarily Revert "Add basic loop fusion pass."Eric Christopher2019-04-171-49/+0
| | | | | | | | As it's causing some bot failures (and per request from kbarton). This reverts commit r358543/ab70da07286e618016e78247e4a24fcb84077fda. llvm-svn: 358546
* [SimplifyCFG] Create attribute for fuzzing-specific optimizations.Matt Morehouse2018-03-221-0/+49
Summary: When building with libFuzzer, converting control flow to selects or obscuring the original operands of CMPs reduces the effectiveness of libFuzzer's heuristics. This patch provides an attribute to disable or modify certain optimizations for optimal fuzzing signal. Provides a less aggressive alternative to https://reviews.llvm.org/D44057.
