- I'd prefer patterns to have a name : that makes output of `-dp' more
readable. Without a name for the pattern, `-dp' will use `andqi3-2' or
something like that. E.g. we could use here `iorqi_bit' and `andqi_bit'.
If the pattern is not used by the expander, like here, it should have a name
starting with '*'. If the condition for the pattern tests anything other
than a global flag (here it does), it *must* have a name beginning with a '*'.
