Detailed Description

A tracker for track NLAs affected by a reduction.

Performs the necessary cleanup steps in order to maintain IR validity after the reduction has applied. For example, removing an instance that forms part of an NLA path requires that NLA to be removed as well.

Member Function Documentation

clear()

void NLARemover::clear ( )

inline

Clear the set of marked NLAs. Call this before attempting a reduction.

Definition at line 131 of file FIRRTLReductions.cpp.

References nlasToRemove.

markNLAsInAnnotation()

void NLARemover::markNLAsInAnnotation ( Attribute  anno )

inline

Mark all NLAs referenced in the given annotation as to be removed.

This can be an entire array or dictionary of annotations, and the function will descend into child annotations appropriately.

Definition at line 167 of file FIRRTLReductions.cpp.

markNLAsInOperation()

void NLARemover::markNLAsInOperation ( Operation *  op )

inline

Mark all NLAs referenced in an operation.

Also traverses all nested operations. Call this before removing an operation, to mark any associated NLAs as to be removed as well.

Definition at line 182 of file FIRRTLReductions.cpp.

remove()

void NLARemover::remove ( mlir::ModuleOp  module )

inline

Remove all marked annotations.

Call this after applying a reduction in order to validate the IR.

Definition at line 135 of file FIRRTLReductions.cpp.
