spu-as input syntax/parser

[Timo Schneider <timo dot schneider at s2004 dot tu-chemnitz dot de>]

Hello,

I am currently writing a program which has to parse Cell BE SPU assembly 
generated, for example, by spu-gcc -S. This is exactly the same that 
spu-as does.

So I thougt I could find the GNU assembly grammar in (E)BNF or alike and 
build a simple parser with flex/bison. Unfortunately I didn't find such a 
grammer neighter in binutils/gas source nor in the binutils/gas manual 
(only a description of the syntax in text form was available there).

Maybe one of you can tell me where to find the binutils/gas input grammar?

Regards,
Timo
