Quite recently AT&T has divulged details of its "Hobbit" microprocessor
(ATT92010) which indicate that it has neither general-purpose registers or
traditional instruction cache, but instead operates with only a stack cache
(and an instruction prefetch/decoded instruction pipeline/cache).

Can anyone shed any light on code development issues for the Hobbit, or on its
performance in executing compiled C code (as it is a direct decendent of the
CRISP archtecture)?
