Hi,

Hopefully this is the correct forum. I have a
Pascal like language using gcc as the backend.
For some reason a call to a simple procedure
with no parameters generates code to initialises eax to zero before the
call. With any parameters in the proc there=E2=80=99s no init.

Is there some way to prevent this init? Some
flag I can set, some arcane piece of wizardry?

Thanks Peter
