* [MergeICmps] Simplify the code.Clement Courbet2019-05-151-9/+9
| | | | | | | | | | | | | | | | | | | Instead of patching the original blocks, we now generate new blocks and delete the old blocks. This results in simpler code with a less twisted control flow (see the change in `entry-block-shuffled.ll`). This will make https://reviews.llvm.org/D60318 simpler by making it more obvious where control flow created and deleted.

| | | | | | | | The reversion apparently deleted the test/Transforms directory. Will be re-reverting again. llvm-svn: 358552
* Temporarily Revert "Add basic loop fusion pass."Eric Christopher2019-04-171-64/+0
| | | | | | | | As it's causing some bot failures (and per request from kbarton). This reverts commit r358543/ab70da07286e618016e78247e4a24fcb84077fda. llvm-svn: 358546
* [MergeICmp] We can discard initial blocks that do other workXin Tong2018-03-051-0/+64
Summary: We can discard initial blocks that do other work We do not need to limit ourselves to just the first block in the chain. Reviewers: courbet, davide Reviewed By: courbet Subscribers: llvm-commits Differential Revision: https://reviews.llvm.org/D44029 llvm-svn: 326698
