Re: PIC versus AVR

AVRGCC - single stack, does something odd when making function calls.

IAR, Rowley, ImageCraft - separate call and data stacks to prevent the
necessity for the above odd thing.

And yet people claim the AVR was designed to be C-friendly.
I've looked at AVR code generaged by GCC and IAR. The AVR is
not C-friendly. It may not be actively hostile like the 8051
or PIC, but it's not C friendly.

Any processor that falls over when you attempt to do any
pointer manipulation isn't C-friendly.

You are probably saying that an 8 bit architecture is inherently
C-unfriendly.
If you start in the other end: How do you make an 8 bit architecture which
is C-friendly
you may come to a different conclusion.

From this viewpoint it is "C-friendly" to use 2 instructions for 16 bit
operations
and 4 instructions to do 32 bit operations.
