 Well, barring wading through the mips.com web site to get the right 
architecture spec (the best and authoritative reference is the REGIMM 
minor opcode map in the "MIPS32 Instruction Set" manual, doc #MD00086, 
table A.4) you could always check mips-opc.c in opcodes (search 
"0x0[4-7].[0-3]....").  There aren't really that many instructions using 
the REGIMM major opcode -- except from branches covered here, there are 
also traps and SYNCI.

 Applied now, thanks.
