Does GCC 3.0.2 on IA64 have COMDAT sections specified by C++ ABI yet? If
not, is there a plan to implement it and when is it going to be available?
Thanks.

Sort-of, but not really. We're still using a gnu binutils feature
that provides similar functionality, but is represented differently
in the ELF object file. The gnu binutils feature pre-dates the new
ELF spec by at least 4 years.
GCC has little to do with this; it's almost all binutils work.

I don't know of anyone working on it.

Thank you very much for response. I still have some questions about COMDAT
to bother you:
Is GCC generating all the information needed for gas to output COMDAT
sections currently? What kind of flags/keywords should the assembler look
for in assembly to identify the information should be put in COMDAT
sections? I've noticed that GCC generated gnu.linkonce sections, are those
COMDAT sections? If so, are all COMDAT sections marked by gnu.linkonce? If
not, what's the difference between them?
Thanks.
