--- Comment #3 from Richard Biener <rguenth at gcc dot gnu.org> ---
Huh, and ::hash is just a UID in some cases? It feels like we're mixing
values and expressions in the same hashtable but only for expressions
hashing makes sense, for values you'd rather use an array where you
then do the lookup doing the walk over locs? That is,
you want a hash-map, mapping expressions to values and the values then
contain the list of all expressions with this value.
Broken data structure?
CCing two more people based on frequence of editing cselib.c
(Jakub wins, Richard is second...).
