Add/Sub/Mul are safe to promote here as well. Incrementing a single-bit
bitfield now gives this code:
_plus:
lwz r2, 0(r3)
rlwimi r2, r2, 0, 1, 31
xoris r2, r2, 32768
stw r2, 0(r3)
blr
instead of this:
_plus:
lwz r2, 0(r3)
srwi r4, r2, 31
slwi r4, r4, 31
addis r4, r4, -32768
rlwimi r2, r4, 0, 0, 0
stw r2, 0(r3)
blr
this can obviously still be improved.
