I saw Ed's reply and thought I'd throw in my two cents. I've been using
Microtec for three years now for 68020 development and while it has gotten
the job done, I'm somewhat less than thrilled. We use both PCs and Micro
VAXs running ULTRIX (Unix) as development platforms and there are some
minor incompatabilities between the two versions. The big problems I've had
are:
1. Until the latest release, they didn't support packed record
structures. i.e. All long and short words are forced to even byte
boundaries. Of course, that's not as big a problem if your doing 68000
work, because the processor makes that requirement anyway. To be fair, I
couldn't find any other vendors that support structure packing either and
the latest Microtec release supposedly does.
2. The compiler would occaisionaly crash if asked to produce a mixed
assembly language listing, i.e. core dump in Unix.
3. The PC version tends to run out of symbol space with relatively small
programs. There is supposedly an EMS fix for this, but I've yet to see it
work. The bottom line is: make sure the compiler does what you need before
shelling out the high price they ask for it. P.S. The PR for the latest
release does look impressive, I'm even considering upgrading after two
years of saying NO THANKS.
