Methods

¶llvm::IVStrideUse& AddUser(
    llvm::Instruction* User,
    llvm::Value* Operand)

Declared at: llvm/include/llvm/Analysis/IVUsers.h:128

Parameters

llvm::Instruction* User

llvm::Value* Operand

¶bool AddUsersIfInteresting(llvm::Instruction* I)

Description

AddUsersIfInteresting - Inspect the specified Instruction. If it is a reducible SCEV, recursively add its users to the IVUsesByStride set and return true. Otherwise, return false.
