Re: Just what makes an architecture "C Friendly"?

In my opinion, probably one of the biggest factors would be the
development tools. By this I mean things like how efficient is the
output code, how much support are provided by the compiler libraries,
how compatible is the compiler and its pre-processor with standard C,
how well does the debugger or emulator handle high level stepping and
hierachy, etc.

Not sure this has much to do with the architecture of a processor. I would
of thought something along the lines of:
+ Easy stack manipulation (C by its nature likes to use a stack).
+ No hard limits on stack size (other than the amount of RAM naturally).
+ Decent number of registers for use by the compiler.
+ Instruction set that is easily mappable to C constructs.
+ etc.

Richard.
