I have the following instruction in my IR-
%call2 = call i8* @strcpy(i8* %1, i8* %2) #2
I intend to change call to strcpy with strncpy. I have included the following code in runOnFunction, so that when it is strcpy’s turn to be invoked, strncpy is invoked instead.
Assuming I* is the strcpy instruction,
CallInst* x=new CallInst::CreateCall3(strncpy,1,2,ConstantInt(16),“my_strncpy”);
I’m running into a whole bunch of errors in CreateCall3(). How can I go about writing this correctly?
Any help would be appreciated.
