Global symbol prefixes

Hey there,
I need a few directions:
I'm porting GAS to my architecture and I'm stuck with global symbol
prefixes.
Since my register operands are not prefixed (e.g. r23 instead of %r23),
I need to prefix global symbols to avoid name collisions.
How do I tell GAS to recognize this prefix?
If I try to assemble
.global %main
%main:
[...]
I am getting errors like
> example.s:1: Error: expected symbol name
> example.s:2: Error: junk at end of line, first unrecognized character
is `%'
The symbol names in the object file though must not have the prefix. It
is only needed at assembly time to solve the name collision problem.
I looked through a few existing ports, but none of them seem to do it
this way. Could anyone give me some advice how to do that?
Regards,
Jan Tlatlik
