/* What the hell is happening here? This looks like a bug
|

waiting to happen. Assume regno = 2*MAX_SPRS_PER_GRP+3,
|
|
which presumably means I want to set register 3 in
|
|
group 2. Instead, I calculate ofs as 3, and regno as
|
|
2, and get a final value of 5??? Is this correct?
|
|
Oh well...I didn't write this. Who knows what it is
|
|
actually supposed to do. It doesn't matter if regno
|
|
is less than MAX_SPRS_PER_GRP, which is the only
|
|
way I use it. CZ - 21/06/01
