Description
|
The logic for commuting binary operations ignores the case where both operations are loads so it doesn't canonicalize them based on idx which can lead to missing GVN opportunities.

Evaluation

The fix is simply to handle Load + x and x + Load explicitly and allow Load + Load to fall through.
