I have a public domain compiler for the amiga which generates separate
entry points for calls with the arguments on the stack or in registers.
This is fairly normal on the amiga, where system calls pass their
arguments through registers.


It is interesting to note that this compiler has various other interesting
aspects to it: a cmd-line flag for generating reentrant code, support for
dynamic linking (that is, select-code-object-at-runtime-and-load-it, not
just shared libraries). Such properties are important/useful on a machine
with no hardware memory protection :-)
