Mark,

Thank you for reviewing my patch.

Your advise is very well-guided. :-)

It sounds reasonable. I'll implement PTRACE_GETREGS/PTRACE_SETREGS
on Linux/M32R kernel and simplify the register handling codes.

Some chips of M32R have FPU. But their target is ECU (Engine Control
Unit) and does not support Linux because ECU doesn't need a large OS
like Linux. So FPU support is not necessary for Linux/M32R.

OK. I'll revise my patch.
