Re: [RFC] Replace some bitmaps with HARD_REG_SETs - second version

[Dimitrios Apostolou]

Bug found, in df_mark_reg I need to iterate until regno + n, not n. The 
error is at the following hunk:

-      bitmap_set_range (set, regno, n);
+      int i;

     }
   else

Many thanks to monoid from IRC for spotting it! I'll post an updated patch 
soon.

Thanks,
