Hi I want to insert some functions into the llvm bitcode ir files. So I use IRBuilder and CreateCall(). But it how error : inlinable function call in a function with debug info must have a !dbg location. I don't know what DebugLoc should I give the new CallInst to setDebugLoc. I Create this CallInst , so this CallInst doesn't hava so-called "DebugLoc" mapping to the source

Hi I want to write a FunctionPass to insert some code before return. Funcion: .. .. .. mov eax,[esp] cmp eax,0x12345678 je 0x12345678 ret (maybe stack will not balance) I wonder that can I get the return address at llvm ir level? I use IRBuilder to CreateICmpEQ and CreateCondBr. but I don't how to get the value of return addrss. I have found there is a Intrinsic::returnaddress. Is Intrinsic::returnaddress can help me? I don't konw how to use Intrinsic::returnaddress because few files use this intrinsic. Thanks -------------- next part ------...
