The assembler code, perhaps, but not the BLISS. Except for data widths
(and even those can be parameterized in header files), BLISS code is
quite machine-independent. In fact, ISTR that the entire front-end of
the Common BLISS compiler (written in Common BLISS, of course) ran
*unchanged* on at least three different architectures.
