I have an ever-increasing need for C cross-compilers for various uP's.
I'm writing this note to solicit any advice or suggestions you may have to

Here's the picture:  My company runs 4.1BSD on several machines (and plans to
acquire some SUNS in short order).  We use UNIX as a development environment to
produce embedded software for a variety of 8 and 16-bitters.  We're wanting to
write this uP software in C because writing assembly code is boring.

So far we've gotten by with C compliers purchased from Whitesmiths'.  We've
hacked these up to emit code for the TMS9900 and the Z80, but we're not keen
on spending six months grinding out another code generator every time a new chip
pops out of Silicon Valley.

We're even more concerned about the licensing morass when we start bringing in
numerous SUN workstations.  Multiply dozens of host machines by the multiplicity
of compilers and our licensing costs grow unpleasantly large.  Now add another
degree of freedom by considering multiple vendors (each with a half-dozen
licensing options) and we see ourselves spending a goodly fraction of a man-
year just trying to keep all the lawyers placated.

So, dear readers, here's the Question of the Day:  Anybody else out there in
the same boat?  Do you have a plan for orderly growth and acquisition of new
cross-compilers?  How do you deal with the combinatorial explosion of

How do you acquire cross-compilers for new $1.98 target machines?  Buy 'em?
>From whom?  Roll your own?  Starting from what base - PCC or something else?
Any advice from One Who Knows?

Drop me a line - I'd love to talk with you.  If nothing else, we can commis-
