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.
