>So you are a bit out of luck here on MIPS [for 64-bit compilers]
64-bit compilers for 64-bit RISC architectures are fairly easy,
at least in the sense that we know what to do. amd64 wasn't quite
as easy because it was non-RISC (and as weird as x86),
had a completely different FP model, and was the first full 64-bit port,
requiring some decisions about the model and (in the end) tweaks to /sys/src/cmd/cc.
(alpha was a 64-bit processor but ran with 32-bit pointers.)
that's all done. based on that, power64 was mostly done in about a week.
it hasn't been much used since then, and might need a bit more work,
but that will be small. i wouldn't expect much more is required for 64-bit mips.
