Thanks both. I looked over the getelementptr and bitcast documentation but I am still a bit confused by one point. lets say i have something like this. union { long Int; double float; long* IntRef; } Since pointer sizes are platform dependent if I am trying to use the union in question with an extern C function is it possible to make write the single definition in a platform independent way? Thanks in advance. --- On Mon, 6/29/09, me22 <me22.ca at gmail.com> wrote: > From: me22...

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.
