Chandler Carruth 71fd27043e [PM/LoopUnswitch] When using the new SimpleLoopUnswitch pass, schedule ... loop-cleanup passes at the beginning of the loop pass pipeline, and re-enqueue loops after even trivial unswitching. This will allow us to much more consistently avoid simplifying code while doing trivial unswitching. I've also added a test case that specifically shows effective iteration using this technique. I've unconditionally updated the new PM as that is always using the SimpleLoopUnswitch pass, and I've made the pipeline changes for the old PM conditional on using this new unswitch pass. I added a bunch of comments to the loop pass pipeline in the old PM to make it more clear what is going on when reviewing. Hopefully this will unblock doing *partial* unswitching instead of just full unswitching. Differential Revision: https://reviews.llvm.org/D47408 llvm-svn: 333493		2018-05-30 02:46:45 +00:00
