Replacing a function from one module into another one
Thank you Ahmad,
I figured out that, although the type of both p(oInst) and p(nInst) were
the same, I had to:
for (unsigned int i = 0; i < callOInst->getNumArgOperands(); i++) {
callOInst->getArgOperand(i)->mutateType(callNInst->getArgOperand(i)->getType());
}
that solves the issue at the calling instruction in the main function, but
now I see that *linkModules* does not work for me (it's a mess to bring all
the other unnecessary functions from the reference module) so what I need
is to directly move one functi...

Replacing a function from one module into another one
Hello LLVM Developers,
I'm trying to replace a function defined in one module into another module
(different files). The first issue I ran into was that llvm::Function does
not have a method "moveBefore" or "moveAfter" as the llvm::BasicBlock or
llvm::Instruction do, so I figured I would just move the BasicBlocks of the
replacing function into the function that was being
