You wrote in earlier message:

    It obviously prevents the ability to create recursive calls to a
    function (except for tail recursion which can always be replaced
    with iteration).

That sounded like you were decribing a compiler that doesn't support
recursion other than tail recursion, i.e. doesn't follow the C standard.
The usual hack of printing decimal numbers using recursion wouldn't
work, for example.  So I'd have trouble calling that a C compiler.

GCC supports that kind of stuff, I thought.

Wait, I explicitly ask for a double and get a single?  That seems pretty
bogus.

Sure, that's reasonable for the library, nothing to do with the
compiler.

Oh that's interesting, I thought the 8051 was supported and I know
the AVR8 is supported.  I wasn't thinking about the 6502 and Z80.

Tons of non-embedded C, a fair amount of 32-bit embedded, and (as you
guessed) no tiny embedded to speak of.  I've been interested in the AVR8
for some things (that's also what originally brought me to c.l.f.)  and
the main toolchain I know of for it uses GCC.

Well, the VM suggestion was from Greg Bailey, the president of GA, who I
figure knows what he's talking about.  He talks about it in his recent
Forth Day video on forth.org, and in fact he more or less pleads for
someone to do it.  (I've put a little thought into it but realistically
have too many other things to pursue).  I figured its purpose was to
allow writing the outer control and UI layer of the user application
using a traditional, relaxed style of C programming rather than a memory
starved one.  GA uses Eforth the same way now--there is a VM for it
programmed into the ROM of the GA144.  I spent a few minutes looking at
the VM code to see if it also seemed suitable for C, but it looks like
it would take some head scratching to figure out what it actually does.

Yeah, I've toyed with the idea of a Haskell EDSL targeted at the GA
nodes, that would attempt whole-program optimization and also give
some compile-time safety checking that couldn't really be done in C.

I'd expect the overriding constraint is the limited code space available
in each node.  Using more nodes would seem to create a lot of
communications requirements that would in turn need even more code to
deal with, etc.  This is why I was asking about diagonal ports so each
node would have 8 neighbors, allowing avoiding some routing of data
around nodes that were in use for other things.
