...it... You are doing this, in LLVM IR: %0 = getelementptr %Value* %firstArg, i32 0 ; i8** %1 = load i8** %0 ; i8* %2 = bitcast i8* %1 to i64* %3 = getelementptr %Value* %secondArg, i32 0 ; i8** %4 = load i8** %3; i8* %5 = bitcast i8* %4 to i64* %6 = load i64* %2 %7 = load i64* %5 Then you call convertDoubleToInt64(). What does this actually do? It's in trouble by this point because it needs to do a fptosi on a double operand, but you've got an i64 operand and you can't reinterpret-cast ints to floats in LLVM IR (AFAIK) I can't see what your code is doing afterwards as it uses calls to helpe...

Hi, I'm pursuing M.Tech course. As a part of the project work i'm using LLVM as back-end. My project area is "Enhancing the performance of V8 javascript engine using LLVM as a back-end". Now i'm writing code for shift left(SHL) operator. I had my own Value Structure .. it's like this Struct Value { void *val ; char type; } The "char type" holds
