Whilst I agree with changing our own definitions & filenames to use n64,
this macro actually reflects naming used by the toolchain. ie:
$ mips-linux-gcc -mips64 -mabi=64 -dM -E - </dev/null | grep ABI64
#define _ABI64 3
#define _MIPS_SIM _ABI64
Our macro here is used to compare against _MIPS_SIM provided by the
toolchain, so for consistency I think we should keep the same name for
the macro that the toolchain uses.
And I realise that undoing that but keeping n64 in our own filenames &
macros is another type of inconsistency, but something imperfect is
unavoidable at this point given that the engineers way back when decided
to use "ABI64" for n64.
Thanks,
Paul
