e11354c0 - [Tests] Remove explicit -enable-mssa-loop-dependency options (NFC)

Sat, 14 Aug 2021 18:54:19 +0000

[Tests] Remove explicit -enable-mssa-loop-dependency options (NFC)This is enabled by default. Drop explicit uses in preparation forremoving the option.Also drop RUN lines that are now the same (typically modulo a-verify-memoryssa option).

da0fe183 - LPM: Drop require from these tests, it's redundant. NFC

LPM: Drop require from these tests, it's redundant. NFCThe LoopPassManager needs to calculate the loops analysis in order toiterate over the loops at all. Requiring it is redundant and just addsnoise to the RUN lines here.llvm-svn: 269097 List of files: /llvm-project-15.0.7/llvm/test/Transforms/LoopSimplifyCFG/merge-header.ll

b417d464 - Add LoopSimplifyCFG pass

Fri, 29 Jan 2016 22:35:36 +0000

Add LoopSimplifyCFG passLoop transformations can sometimes fail because the loop, while invalid rotated LCSSA form, is not in a canonical CFG form. This isan extremely simple pass that just merges obviously redundantblocks, which can be used to fix some known failure cases. In thefuture, it may be enhanced with more cases (and have code shared withSimplifyCFG).This allows us to run LoopSimplifyCFG -> LoopRotate -> LoopUnroll,so that SimplifyCFG cleans up the loop before Rotate tries to run.Not currently used in the pass manager, since this pass doesn't doanything unless you can hook it up in an LPM with other loop passes.It'll be added once Chandler cleans up things to allow this.Tested in a custom pipeline out of tree to confirm it works inpractice (in addition to the included trivial test).llvm-svn: 259256 List of files: /llvm-project-15.0.7/llvm/test/Transforms/LoopSimplifyCFG/merge-header.ll
