Bob,

It was Byte Craft Ltd.'s C6805 compiler that really turned my head in the C
vs. asm "war" all the way back in the late 80's or very early 90's. I was
working on a 6805 project and the client insisted the code be written in C.
I was resistant and tossed out all the arguments that have run their course
in this thread in favor of asm. I had about 7 or 8 years of 6805 assembler
programming experience and would say if not an expert at least very
experienced.

After I wrote my first few short programs with the C6805 compiler I was
astonished that the code was as compact as I'd write -- in fact much of the
code was translated exactly as I'd write the assembler. In some cases (and
this is where Walter is really correct) the compiler did things that
weren't immediately intuitive on inspection but in reality saved code
space, execution time or both.

We write our code here almost entirely in C now, even for the tiny
processors. The C compilers for embedded micros have gotten so good that
it's difficult to find a truly bad one these days. Most are quite
excellent.
