[PATCH] D85548: Allow fneg + strict_fadd -> strict_fsub in DAGCombiner

[Andrew J Wock via Phabricator via llvm-commits]

ajwock added a comment.

This combine does create the strict_fsub in terms of strict_fadd while preserving the chain-protected ordering.  Would it still be appropriate to have this transform and others like it in the DAGCombiner?
