Yes, I can confirm now that v13 has been tested on other MIPS variants and it
is good to go.

This seems to be related to the way how MIPS port uses and handles
DivModU128to64 and some other Iops.
The issue comes from tricks done due to the lack of appropriate Iops that I am
considering to add now.
These would be:
Iop_DivModU64to64, // :: I64,I64 -> I128
// of which lo half is div and hi half is mod
Iop_DivModS32to32, // :: I32,I32 -> I64
// of which lo half is div and hi half is mod
Iop_DivModU32to32, // :: I32,I32 -> I64
// of which lo half is div and hi half is mod
Does anyone object or is there a need to create a separate issue for it?
