Seems reasonable to me with a couple minor edits.

An old bug -- can you change the length of div_trap_normal to "3", since it
can generate 3 insns in some cases.

If the mips16 is using an a macro, then odds are it has a length > 3;
can you find out what length it has and update the div_trap_mips16
insn appropriately?

Consider the approved with those changes.
