[LLVMdev] simulating c style unions in LLVM

[Carter Cheng]

I am trying to create a boxed tagged datatype for a language where it is necessary to resolve the type at runtime. If I were writing an interpreter in C- it would most likely look something like this-

struct
{
    unsigned tag;
    union { long Int; double Float; .... }
}

Is there a standard way for constructing a type like this in LLVM?

Thanks again.
