Does it? I haven't seen any code to emulate trap, branch likely, dword
coprocessor transfer instructions. What is emulated are only the ll and
sc instructions, but they are only a small subset of MIPS II extensions
which is never used by gcc, unlike the others.

If a target triplet defines a CPU, it should always be used as the
default for uniformity.
