Function Documentation

◆ createSubApply()

static AffineApplyOp createSubApply	(	RewriterBase &	rewriter,
		AffineApplyOp	originalOp,
		AffineExpr	expr
	)

static

Build an affine.apply that is a subexpression expr of originalOps affine map and with the same operands.

Canonicalize the map and operands to deduplicate and drop dead operands before returning but do not perform maximal composition of AffineApplyOp which would defeat the purpose.

Definition at line 85 of file DecomposeAffineOps.cpp.

◆ numEnclosingInvariantLoops()

static int64_t numEnclosingInvariantLoops ( OpOperand & operand )

static

Count the number of loops surrounding operand such that operand could be hoisted above.

Stop counting at the first loop over which the operand cannot be hoisted.
