Any  compiler from the last decade will take notice of the scope in which  variables are used and will reuse stack (or register) space if the  value they hold is no longer needed/used. I'm with John here, clarity  in the naming of variables is much more important.

Well, if the single "tmp" approach is not good, the current approach
that uses reg_init even for the led_polarity is not good either...
