2002-08-01 Kevin Buettner <kevinb@redhat.com>
* mips-tdep.c (mips_register_virtual_type): New function.
(mips_gdbarch_init): Register mips_register_virtual_type()
with gdbarch machinery.
* config/mips/tm-irix6.h (mips/tm-bigmips64.h): Include
this file instead of tm-bigmips.h.
(MIPS_REGSIZE): Delete this macro.
(REGISTER_VIRTUAL_TYPE): Delete macro. Undef macro so that
multiarch version in mips-tdep.c will be found.
2002-08-01 Andrew Cagney <cagney@redhat.com>
* NEWS: Menion that CHILL has been made obsolete.

reproduce the behavior of each of the REGISTER_VIRTUAL_TYPE

the ``FCRCS_REGNUM <= reg && reg <= LAST_EMBED_REGNUM'' clause
