Oops, Sorry, I took that as read.  Same with  FP regs, I think.

Isn't there  an FPU bit to enable the 64-bit FP registers.
If so, I have no idea how to set it for binaries compiled with -mfp64
that are otherwise mips1 binaries, Unless we use separate ECOFF or ELF
code for those binaries, but I don't know off-hand of such codes.


I also don't see any switch to control FP argument-passing,
independently of -mfp64.

Ted?  Did you just compile whole systems with -mfp64?
