Function - replaceAllUsesWith
...y try overloading “puts” with a custom address before I start the JIT process. I want to replace the call to “puts” with my own address. For a test purpose I tried this now:
mainModue->getFunction("puts")->replaceAllUsesWith(
llvm::ConstantExpr::getPointerCast(
llvm::ConstantInt::get(llvm::IntegerType::get(context, 64), 0xF),
mainModue->getFunction("puts")->getType()
)
);
This code will crash the application though. I know that 0xF is not a correct ad...

I'm virtually certain it is. I think lldb does it, in fact. You mentioned the pointercast didn't work, but didn't give any details on how or what actually crashed. Do you have more you can tell us?
Also, hopefully you're using a build of LLVM with assertions enabled, that'll catch errors much earlier.
Cheers.
