 Well, actually I disagree.  I like this very much, since looking at the
output it's immediately obvious if some code contains opcodes
unrecognizable by a selected CPU (due to a bad compiler option or an
inline asm error).  And you can always select a desired CPU type with the
"-m mips:<model>" option (e.g. "-m mips:3000").  If there are MIPS I CPUs
which have have ll but no branch likely, etc. then their descriptions
should be appropriately set in objdump.  Otherwise, it's a bug in
