while compiling db2 i got the configure warning "spinlocks not implemented
for this compiler/architecture" - I guess as we do not currently have
SMP machines (except the ones ralf is working on) we dont have a problem,
but how should the spinlocks be implemented ?
I mean - normally "ll" and "sc" are needed - But those are not
available on R3000 - And spinning in an ll/sc loop and emulating
them with exceptions isnt that fast.
OTOH - Where are they normally implemented ? libc ? macro ? Could
there be a runtime linking thing with a cpu detection wether we
have ll/sc or not ?

Why is it called "common sense" when nobody seems to have any?
