It makes some of these names illegal, this might break compatibility
to existing source. Btw, it looks like you have choosen $t0 $t1 etc,
not t0 t1 etc. It also does not work for new ABI names, breaking such
code surely.

The solution I know of is to do defines via a preprocessor.
This circumvents the problem without losing much.
