I think that the CVSup failure one person reported was caused by the
fact that I'm not currently saving/restoring the floating point state
on thread context switches. I need to find out how to do that. It
looks like if I save and restore the FSR and the FPRS and %q0 through
%q60, that will do it. Am I missing anything?
What is the most straightforward way to save all of the %qN registers?
Like this?
stq %q0, ...
stq %q4, ...
stq %q8, ...
[...]
stq %q60, ...
Thanks,
John
