class VPCanonicalIVPHIRecipe

Declaration

class VPCanonicalIVPHIRecipe : public VPHeaderPHIRecipe { /* full declaration omitted */ };

Description

Canonical scalar induction phi of the vector loop. Starting at the specified start value (either 0 or the resume value when vectorizing the epilogue loop). VPWidenCanonicalIVRecipe represents the vector version of the canonical induction variable.
