This is already implemented, parts of it are in CVS. > Sounds like everything else is okay.

Will let you know. This needs an SSA graph of the data flow? BTW, looking at analyse_life_block() it seems that this allocates unconditionally a Life_range structure. As these are O2 in (n_symbols * n_basic_blocks) we could safe huge amounts of memory, by defining that a missing life block propagates the previous one. Dunno if its possible, though. leo
