Actually that seems to be the problem - on r600, rcp/rsq_clamped are used (=
btw
does someone know why rsq has its own code expansion on r600, but not
eg/cayman)?
But eg/cayman use rcp/rsq_ieee. It looks like if I use rcp_clamped instead =
that
is enough to fix everything (regardless what rsq/min/max are using).
