We (OSF) are using a version of gdb based on Per Bothner's patches to
gdb 3.5 for the DECstation. Here are some fixes to mips-opcode.h which
fix the incorrect disassembly of the mfc1, cfc1, and ctc1
instructions. Also, the cvt.d.w and cvt.s.w instructions were missing
altogether - they are added here.

Apply the following context diff to your version. Line numbers may be
off slightly because of an edit history kept in our version:
