◆ match() [1/2]
|
inlineoverridevirtual |
Check if the reduction can apply to a specific operation.
Returns a benefit measure where a higher number means that applying the pattern leads to a bigger reduction and zero means that the patten does not match and thus cannot be applied at all.
Implements circt::Reduction.
Definition at line 85 of file Reduction.h.
◆ match() [2/2]
|
inlinevirtual |
Reimplemented in NodeSymbolRemover, EagerInliner, ExtmoduleInstanceRemover, InstanceStubber, RootPortPruner, and FIRRTLModuleExternalizer.
Definition at line 94 of file Reduction.h.
◆ rewrite() [1/2]
|
inlineoverridevirtual |
Apply the reduction to a specific operation.
If the returned result indicates that the application failed, the resulting module is treated the same as if the tester marked it as uninteresting.
Implements circt::Reduction.
