I suspect it doesn't.  There is nothing in the news file.

GDB does support a number of 64 bit MIPS ABIs (eg EABI64) and that could
well be very like the ABI used by -64.  You can build a GDB supporting
these ABI's using targets like mips64-elf and mips64vr5000-elf.

Any way, I'd suggest trying to build a GDB using something like:

	CC="cc -64" ../gdb-5.0/configure

This forces the IRIX 64 bit ABI to be used and hopefully that gets
things like procfs.c built using the correct headers.
