To be able to use the mac.w instruction for implementing the ssmaddhisi4
pattern I think the already existing mode-switching facilities can be used, as
it is done for float/double mode switching.
Even without doing SR.S mode switches, before any mac instructions can be used,
we must make sure that the SR.S bit is in a defined state at function entry and
function leave.
Kaz, do you think it is safe to assume that SR.S = 0 at function entry?
