getIdentityValue()

virtual bool ReductionCat::getIdentityValue ( ) const

pure virtual

Return the unit value for this reduction operation:

Implemented in OrRCat, AndRCat, and XorRCat.

handleConstant()

virtual bool ReductionCat::handleConstant ( mlir::PatternRewriter &  rewriter, Operation *  op, ConstantOp  constantOp, SmallVectorImpl< Value > &  remaining  ) const

pure virtual

Handle a constant operand in the cat operation.

Returns true if the entire reduction can be replaced with a constant. May add non-zero constants to the remaining operands list.
