Member Function Documentation
◆ beforeReduction()
|
inlineoverridevirtual |
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.
Definition at line 182 of file HWReductions.cpp.
◆ getName()
|
inlineoverridevirtual |
Return a human-readable name for this reduction pattern.
Implements circt::Reduction.
