[PATCH] D60601: [DAGCombiner] Exploiting more about the transformation of TransformFPLoadStorePair function

[Eli Friedman via Phabricator via llvm-commits]

I can't find any previous discussion of this particular check.  I agree it isn't necessary for correctness.

Do you have any benchmarks showing this actually helps?  I'm a little concerned that this might not be a performance win in practice due to register pressure.
