Unfortunately I'm not familiar enough with gas to tell either, but ...

I tried this and it fixed my problem!  I also recompiled the entire
linux kernel using the fixed gas, and compared disassemblies, and there
seem to be no regressions caused by this change (I think linux is a
better test than most because it uses a fair amount of embedded
assembly).

So ... looks reasonable to me.

Are you in a position to apply/send a patch, or do you want me to do
something?

Thanks very much,
