void IntrinsicLowering::AddPrototypes

(

Module &

M

)

AddPrototypes - This method, if called, causes all of the prototypes that might be needed by an intrinsic lowering implementation to be inserted into the module specified.

void IntrinsicLowering::LowerIntrinsicCall

(

CallInst *

CI

)

LowerIntrinsicCall - This method replaces a call with the LLVM function which should be used to implement the specified intrinsic function call. 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.
