If I understand right, you are not able to compile your code with
gccxml and the reason is "_asm" function usage.

I think, that this is a bug in gccxml and it could be fixed by Brad
King, gccxml author.

I suggest you to create small example and send it to him (
http://www.gccxml.org/mailman/listinfo/gccxml )

The current work-around is to move\comment the function body.
