If (.B) is selected as the size specifier (.size), the flag is set when the operation results in MSB =
1; otherwise cleared. The flag does not change if (.W) is selected as the size specifier (.size).
If (.B) is selected as the size specifier (.size), the flag is set when the operation results in 0;
otherwise cleared. The flag does not change if (.W) is selected as the size specifier (.size).
