Member Function Documentation

◆ acceptSizeIncrease()

bool MemoryStubber::acceptSizeIncrease ( ) const
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 480 of file FIRRTLReductions.cpp.

◆ afterReduction()

void MemoryStubber::afterReduction ( mlir::ModuleOp  )
inlineoverridevirtual

Called after the reduction has been applied to a subset of operations.

Reductions may use this callback to perform post-processing of the reductions before the resulting module is tried for interestingness.

Reimplemented from circt::Reduction.

Definition at line 415 of file FIRRTLReductions.cpp.

◆ beforeReduction()

void MemoryStubber::beforeReduction ( mlir::ModuleOp  )
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 414 of file FIRRTLReductions.cpp.

◆ getName()

std::string MemoryStubber::getName ( ) const
inlineoverridevirtual

Return a human-readable name for this reduction pattern.

Implements circt::Reduction.

Definition at line 479 of file FIRRTLReductions.cpp.

◆ rewrite()

LogicalResult MemoryStubber::rewrite ( firrtl::MemOp  memOp)
inlineoverridevirtual
