AW: A new cross

[Hansjörg Petriffer <hpetriffer at grips dot com>]

Hello I have one question to a port too. I need for the H8 an ELF compiler.
The original can make only the coff format. How much time do you think take
the time?

Thanks
Hansjörg

Yes.  We did a port to the Motorola HC11, HC12, and HC16 starting about five
years ago.  You can see the result at http://www.realtime.bc.ca.

We did gcc first; it took about three man-months for the first CPU and
considerably less for the other two.  We did gas and ld later; these took
about one man-month.

At the time, we had only the gcc docs and the source.  The trick is to find
an existing port that's either similar to your target, or is extremely
simple, and use it as a starting point.  We used the we32k port, if memory
serves.

By the way, what machine do you have in mind?
