Member Function Documentation
◆ acceptSizeIncrease()
|
inlineoverridevirtual |
Return true if the tool should accept the transformation this reduction performs on the module even if the overall size of the output increases.
This can be handy for patterns that reduce the complexity of the IR at the cost of some verbosity.
Reimplemented from circt::Reduction.
Definition at line 78 of file HWReductions.cpp.
◆ 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 60 of file HWReductions.cpp.
References ModuleSizeCache::clear(), instanceGraph, and moduleSizes.
◆ getName()
|
inlineoverridevirtual |
Return a human-readable name for this reduction pattern.
Implements circt::Reduction.
