Well, for every processor that I have used there is a similar (or same)
method of allocating space for parameters. I have noticed as time goes by
that more registers were used, but when we talk of the (braindead) x86 we
need to step back 20 years, as the CPU's of the time were more advanced and
the conventions that were being proposed were also becoming irrelevant as
the x86 was becoming more accepted.

I worked originally on the Amiga where the convention was to use the
registers (and hence not to create a new stack frame on every call), we
have stepped back 20 years (wrt x86) by having to provide a limited set of
parameters in registers (4 or 5 - if not less) and then to provide
everything else in stack.

So, as far as I am concerned there is still a C & PASCAL convention, it's
just a matter of how the compiler works I suppose.
