* Copy utilities updated and added for MI flagsMichael Berg2018-09-191-1/+1
| | | | | | | | | | | | | | Summary: This patch adds a GlobalIsel copy utility into MI for flags and updates the instruction emitter for the SDAG path. Some tests show new behavior and I added one for GlobalIsel which mirrors an SDAG test for handling nsw/nuw.

* [Hexagon] Simplify CFG after atomic expansionKrzysztof Parzyszek2018-08-021-1/+1
| | | | | | | | | | This will remove suboptimal branching from the generated ll/sc loops. The extra simplification pass affects a lot of testcases, which have been modified to accommodate this change: either by modifying the test to become immune to the CFG simplification, or (less preferablt) by adding option -hexagon-initial-cfg-clenaup=0. llvm-svn: 338774
