Hello

gcc 3.0.4 is rather old at this point. Would it be possible for you to check whether this problem 
still occurs with gcc 3.3? Thanks,

Dara

Thanks - we're actually having some trouble building version 3.3 right now, let 
alone testing the problem!

Bug still exists in 3.3.1, in case anybody cares.

In the general case of calling library support functions, this really needs
fixing in the linker.  I'm going to fix this for the specific case of
__call_via_<rn> because this is necessary to generate code that conforms to the
EABI (__call_via_<rn> isn't a recognized library entry point).

Fixed for the common case, but not for caller super-inteworking.  I don't intend
to change that case, since that's outside the EABI and I still think the linker
should be fixing these types of problems up with linker-generated stubs.
