As maintainer of 68HC11/68HC12 port I receive this request regularly
(for HC08 or HC05). The HC05/08 are close to the HC11/HC12 with only 2
registers instead of 3 (A + X). It was a real nightmare for me to port
on HC11
due to this small register architecture. But now, gcc generates very good
code that beats commercial compilers.
Which raises another question: Another very common embedded
microcontroller architecture is the 8051-based processors. A lot of
people (at regular intervals) ask about GCC support for the 8051. The
8081 architecture is probably very similar to the HC11. It incorporates
one accumulator and 7 semi-generic registers. What woul your comment be
about porting gcc to this target?
