[PATCH] D18905: [ValueTracking] Improve isImpliedCondition for conditions with matching operands.

[Chad Rosier via llvm-commits]

mcrosier retitled this revision from "[ValueTracking] Improve isImpliedCondition for conditions with matching but swapped operands." to "[ValueTracking] Improve isImpliedCondition for conditions with matching operands.".
mcrosier updated this revision to Diff 53559.
mcrosier added a comment.

-Make this patch much more general by not insisting the operands be swapped.
-Address the FIXME by handling the remaining comparisons (e.g., A == B implies A >B, A <B, and A != B are false, etc.).

Passes all correctness test for the test-suite, SPEC200X, EEMBC and a clang bootstrap.

I believe this is in pretty good shape.

Chad
