>From what I understood of the armv7 calling convention, it should be relatively easy to get that working, as it seems to be pretty similar to what we have for x86_64 or arm64.
Mips on the other hand has a whole bunch of special rules that will need to be put in place, especially when floats/doubles come into the equation, incuding, but not limited to:
 - a float/double passed as first argument is always in $f12
 - a float/double in second argument will be in $f14 if the first argument is a float/double, but in $a3 (or $a3 and $a4 for double) if the first argument is integral.
