Functions
template
static CallInst *	ReplaceCallWith (const char NewFn, CallInst CI, ArgIt ArgBegin, ArgIt ArgEnd, Type *RetTy)
	This function is used when we want to lower an intrinsic call to a call of an external function.
static Value *	LowerBSWAP (LLVMContext &Context, Value V, Instruction IP)
	Emit the code to lower bswap of V before the specified instruction IP.
static Value *	LowerCTPOP (LLVMContext &Context, Value V, Instruction IP)
	Emit the code to lower ctpop of V before the specified instruction IP.
static Value *	LowerCTLZ (LLVMContext &Context, Value V, Instruction IP)
	Emit the code to lower ctlz of V before the specified instruction IP.
static void	ReplaceFPIntrinsicWithCall (CallInst CI, const char Fname, const char Dname, const char LDname)

◆ LowerBSWAP()

◆ LowerCTLZ()

◆ LowerCTPOP()

◆ ReplaceCallWith()

This function is used when we want to lower an intrinsic call to a call of an external function.

This handles hard cases such as when there was already a prototype for the external function, but that prototype doesn't match the arguments we expect to pass in.
