Subject: Stack in a non-zero address space?

Hi,

We're currently looking at moving our stack out of the address space that
contains the heap and globals (and, actually moving those into separate
address spaces, but that seems easier).  Currently, however, there seems to
be an assumption that alloca instructions always return a pointer into
address space 0, and the verifier enforces this.

Is anyone else encountering this problem?  Are there any assumption in
optimisers that rely on it?
