And even if you are just generating a small bit of embedded code

PC you probably were not thinking of running GCC out of a dozen
words of target ROM.

Huh?

Unless I'm misunderstanding something, we're not talking about the platform
that the C compiler runs on. That's of no interest (to me). We're talking
about the target it compiles for.

As for "it is becoming an option more often to take the library and file
system and OS from development platform to the embedded
target with the minimal effort" - if you're talking about embedded PCs,
fine. Again that's of no interest to me, and I don't see how it's relevant
to this thread.


I've been using a 32 bit processor with MMU running Linux as a
fairly deeply embedded processor for years. The source is 100%
compilable with the PC (development system) as a target, and
about 80% functionally portable between the development system
and the actual embedded target. I think that's what he means.

And yes, the development system for the processor was the starting
point. Axis provides a stable starting point, royalty free tools and
Linux and GCC ports.

The target filesystem and minimal user space (mostly BusyBox)
on the embedded target would not be suitable for a PC, and I
don't think that was an argument.
