Function - replaceAllUsesWith
...would need to at least cast this pointer value to the right type, and use an indirect call.
Hey Mehdi,
I simply 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()...

Function - replaceAllUsesWith
I could actually track down the cause of the problem:
mainModue->getFunction("puts")->replaceAllUsesWith(
llvm::ConstantExpr::getPointerCast(
llvm::ConstantInt::get(llvm::IntegerType::get(context, 64), 0xF),
mainModue->getFunction("puts")->getType()
)
);
The problem is the line where I receive the type of the function "puts...

Function - replaceAllUsesWith
Hey Tim,
Sadly I have currently only a release build of LLVM7 with no assertions turned on... So I just know that the line of code I posted is crashing.
No output, no anything....just...Crash...
Kind greetings
Björn

Can I use the JIT interface to create trampolines? (For functions and global values)
...ear LLVM-Mailing list (again),
I still have another beginners question in my mind - thank you for your patience.
Again I was playing around, but this time with llvm::Function. In an older question I learned, that I can replace a llvm::Function directly with an address.
llvm::Function *function = mainModue->getFunction("puts");
function->replaceAllUsesWith(
llvm::ConstantExpr::getIntToPtr(
llvm::ConstantInt::get(llvm::IntegerType::get(context, 64), 0xF),
function->getType()
)
);
With th...

Function - replaceAllUsesWith
Hello LLVM-World,
currently I play around with a "llvm::Module" and an external function defined there "puts". Normally this function gets resolved in the JIT-Process but I wonder about two things:
1. Can I resolve the function already in this step? I used "replaceAllUsesWith" and passed a "llvm::ConstantInt" to the function. But this didn't

Hi Björn
What does the IR code look like when you dump your module?
llvm::outs() << mainModule;
I guess for the external function "puts" it will have a declaration like this:
declare i32 @puts(i8*)
When loading your module in the JIT, RuntimeDyld will resolve it to an actual address. This lookup is done by name and it happens in a stage called external symbol resolution. You sh...

Setting a function in a module to extern
But in my module this function already exist… I first want to delete it but without also deleting the calls to it…
