Something like: // Once, M = llvm::Module*, C = LLVMContext&: FunctionType *AbortFTy = FunctionType::get(Type::getVoidTy(C), false); Function *AbortF = Function::Create(AbortFTy, GlobalValue::ExternalLinkage, "abort", M); // Each call site: CallInst *abort = CallInst::Create(AbortF, ...

Guys, I would like to instrument the bytecode that LLVM produces with assertions. I have written the instrumentation code manually, but I do not know how to halt the program in case the assertion is false. I took a look into the bytecode that LLVM produces for a program like: #include <stdlib.h> int main() { exit(1); } And it is like this: define i32 @main() nounwind { entry:

...th some assertions, and to do this, I want to insert the abort() function into the bytecode. The problem is that LLVM is creating a new abort() function, instead of using the one that already exists in libc. Let me show my code to add the abort into the code: // Create abort function FunctionType *AbortFTy = FunctionType::get(Type::getVoidTy(*context), false); Function *AbortF = Function::Create(AbortFTy, GlobalValue::ExternalLinkage, "abort", &M); // Call to abort function CallInst *abort = CallInst::Create(AbortF, Twine(), assertfail); // Add atributes to the abort call instructio...
