[sdcc-devel] Merging the Rabbit2000 branch

[Philipp K. K. <pk...@sp...>]

Leland Morrison's Rabbit 2000 port is doing quite well. I've created the
Rabbit2000 branch for it and did a little bit of work on it as well.

It can generate code for the Rabbit 2000 / Rabbit 3000, which will work
on the 3000A, too (but it does not use any of the special Rabiit 3000A
instructions).

It passes the regression tests.

The assembler has been derived from the asz80 assembler.
The simulator has been integrated with the z80/z180 ucsim simulator.

It already uses some of the Rabbit's additional (over z80) instructions,
such as mul, ld iy, hl and add sp, d.

The MSVC files might need to be updated, I don't know. Could a MSVC use
have a look?

I'd like to merge this port soon.

Missing features include bank switching and more use of the new
instructions.

Like the z80 port, is uses the new optimal register allocator, has full
support for bool, basic support for long long, etc.
