[PATCH] D85047: [Hexagon] Use InstSimplify instead of ConstantProp

[Krzysztof Parzyszek via Phabricator via llvm-commits]

kparzysz added a comment.

These failures seem to be caused by optimizing the code "too much", and simply removing the parts that the tests were looking for.

Could you add a debug flag in HexagonTargetMachine.cpp, and add the simplification pass conditionally, similarly to how line 322 does it?  The pass would be added by default, but these failing tests could exclude it (see the `-hexagon-initial-cfg-cleanup=0` in some of the failing tests, that's the exact same problem caused by some other change in optimization passes).
