implement shift.ll:test25. This compiles:
struct S { unsigned int i : 6, j : 11, k : 15; } b;
void plus3 (unsigned int x) {
b.k += x;
}
to:
_plus3:
lis r2, ha16(L_b$non_lazy_ptr)
lwz r2, lo16(L_b$non_lazy_ptr)(r2)
lwz r3, 0(r2)
rlwinm r4, r3, 0, 0, 14
add r4, r4, r3
rlwimi r4, r3, 0, 15, 31
stw r4, 0(r2)
blr
instead of:
_plus3:
lis r2, ha16(L_b$non_lazy_ptr)
lwz r2, lo16(L_b$non_lazy_ptr)(r2)
lwz r4, 0(r2)
srwi r5, r4, 17
add r3, r5, r3
slwi r3, r3, 17
rlwimi r3, r4, 0, 15, 31
