Lunderberg opened a new pull request, #15494:
URL: https://github.com/apache/tvm/pull/15494
Prior to this commit, the commutative pattern matching was enabled based on
the operation in the pattern. As a result, commutative matches would only be
checked if the match checked for a single operator, but not if the operator was
itself a pattern that resolved to a commutative operator.
```python
pattern_add = ExprPattern(Op.get("relax.add"))
pattern_mul = ExprPattern(Op.get("relax.multiply"))
uses_commutative_matching = pattern_add(lhs, rhs)
no_commutative_matching = OrPattern(pattern_add, pattern_mul)(lhs, rhs)
```
This commit updates the pattern matcher to check against the matched
operator, rather than the pattern, to determine whether to check for
commutative matches.
