the two operations together. This allows us to compile this:
void %two(int %a, int* %b) {
%tmp.2 = seteq int %a, 0
%tmp.0.0 = select bool %tmp.2, int 10, int 20
store int %tmp.0.0, int* %b
ret void
}
into:
two:
save -96, %o6, %o6
or %g0, 20, %l0
or %g0, 10, %l1
subcc %i0, 0, %l2
be .LBBtwo_2 ! entry
nop
.LBBtwo_1: ! entry
or %g0, %l0, %l1
.LBBtwo_2: ! entry
st %l1, [%i1]
restore %g0, %g0, %g0
retl
nop
instead of:
two:
save -96, %o6, %o6
sethi 0, %l0
or %g0, 1, %l1
or %g0, 20, %l2
or %g0, 10, %l3
subcc %i0, 0, %l4
