Ah, yes, indeed!  I had mis-read your report.  If the message comes
from the assembler, then it seems to be the case that the assembler
doesn't support the opcode you're using, or it expects it to be
written in a different way.  In either case, the GCC mailing list is
not the best place to discuss assembler issues: the binutils mailing
list is (as long as you're using GNU as :-).
