/* The minimum stack frame size (bytes) is:
* 16 extended words for saving the current register window,
* 1 extended word for "hidden parameter",
* 6 extended words in wihch a callee can store its arguments
* ("The SPARC Architecure Manual" by Weaver & Germond)
* This gives 184 bytes. However we must round up to an extended
* word boundary, thus 192 bytes.
* (if we weren't v9, it would be 96 bytes rather than 192)
