"Unfortunately, it isn't too useful because the answer is a strong
function of who's doing it and how "peculiar" the machine in question is.

For example, I did the GCC config files for the RS/6000 in about a
month of elapsed time, working about 50% of my time on that.  Much of
that time was spent fighting IBM's assembler.

The Alpha was faster since the assembler problems didn't exist."

Of course, getting to the first version of the GCC config files is only
part of producting a complete port in a productized form, but still we
are typically talking of perhaps a person year in all, so not a big effort.
Certainly it is probably just as easy to create a new MD fie for GCC as
it would be to get a compiler working via a C translation, and you get
much better results from the former approach.
