class IVStrideUse

Declaration

class IVStrideUse : public CallbackVH, public ilist_node { /* full declaration omitted */ };

Description

IVStrideUse - Keep track of one use of a strided induction variable. The Expr member keeps track of the expression, User is the actual user instruction of the operand, and 'OperandValToReplace' is the operand of the User that is the use.

Declared at: llvm/include/llvm/Analysis/IVUsers.h:34

Inherits from: CallbackVH, ilist_node

Member Variables

private llvm::IVUsers* Parent

Parent - a pointer to the IVUsers that owns this IVStrideUse.

private llvm::WeakTrackingVH OperandValToReplace

OperandValToReplace - The Value of the operand in the user instruction that this IVStrideUse is representing.

private llvm::PostIncLoopSet PostIncLoops

PostIncLoops - The set of loops for which Expr has been adjusted to use post-inc mode. This corresponds with SCEVExpander's post-inc concept.
