class IntrinsicLowering

Declaration

class IntrinsicLowering { /* full declaration omitted */ };

Declared at: llvm/include/llvm/CodeGen/IntrinsicLowering.h:25

Method Overview

• public IntrinsicLowering(const llvm::DataLayout & DL)
• public void LowerIntrinsicCall(llvm::CallInst * CI)
• public static bool LowerToByteSwap(llvm::CallInst * CI)

Methods

¶IntrinsicLowering(const llvm::DataLayout& DL)

Declared at: llvm/include/llvm/CodeGen/IntrinsicLowering.h:31

Parameters

const llvm::DataLayout& DL

¶void LowerIntrinsicCall(llvm::CallInst* CI)

Description

Replace a call to the specified intrinsic function. If an intrinsic function must be implemented by the code generator (such as va_start), this function should print a message and abort. Otherwise, if an intrinsic function call can be lowered, the code to implement it (often a call to a non-intrinsic function) is inserted _after_ the call instruction and the call is deleted. The caller must be capable of handling this kind of change.

Parameters

llvm::CallInst* CI

¶static bool LowerToByteSwap(llvm::CallInst* CI)

Description

Try to replace a call instruction with a call to a bswap intrinsic. Return false if the call is not a simple integer bswap.
