I am sorry.. I think u got me wrong. I have had a look at the source
code. I am actually trying to find out WHY and WHEN peep2_reg_dead_p
was introduced. I checked the mailing list but dint find anything
relavent. Are cleanliness of the code and compile time efficiency the
only reasons? I mean is that why they introduced peep2_reg_dead_p?
