◆ beforeReduction()

void ModuleInputPruner::beforeReduction ( mlir::ModuleOp )

Called before the reduction is applied to a new subset of operations.

Reductions may use this callback to collect information such as symbol tables about the module upfront.

Reimplemented from circt::Reduction.

Return a human-readable name for this reduction pattern.

Implements circt::Reduction.
