define i3 @src(i3 %a, i3 %b, i3 %c) {
%0:
%or1 = or i3 %b, %c
%not1 = xor i3 %or1, 7
%and1 = and i3 %a, %not1
%xor1 = xor i3 %b, %c
%or2 = or i3 %xor1, %a
%not2 = xor i3 %or2, 7
%or3 = or i3 %and1, %not2
ret i3 %or3
}
=>
define i3 @tgt(i3 %a, i3 %b, i3 %c) {
%0:
%obc = or i3 %b, %c
%xbc = xor i3 %b, %c
%o = or i3 %a, %xbc
%and = and i3 %obc, %o
%r = xor i3 %and, 7
ret i3 %r
}
Transformation seems to be correct!
