And how is a stack allocated? I assume we’re talking assembly here? The link I posted (http://www.festra.com/wwwboard/messages/12899.html) seems to do this but I don’t know assembly so I’m just guessing. Even if you allocated a stack frame doesn’t it need to be populated with all local variables in the current scope? In my short time working on the compiler I haven’t looked at the actual code generator so I don’t know how the stack works. However, in theory you should be able to make a compiler intrinsic that wraps this process for you.
