For MIPS I've done some experiment with this and the result (with N64 ABI) is:
With GCC trunk, G++ trunk, and GCC 11.2: argument passed via FPR $f12 and GPR
$5,
returned via GPR $2 and $3
With G++ 11.2: argument passed via FPR $f12 and $f13, returned via FPR $f0 and
$f2
So I guess we need -Wpsabi for both mips_function_arg and
mips_fpr_return_fields.
