------- Comment #6 from dberlin at gcc dot gnu dot org 2007-07-11 22:20 ------- Subject: Re: [4.3 regression] ICE in set_ssa_val_to, at tree-ssa-sccvn.c:1022
The only way i can see this happening is if you have a truly uninitialized variable, or there is something we have missed. Does this function have cfun->static_chain_decl being used, and we have a copy of that here? It is theoretically safe to call set_ssa_to_val with to == vn_top, but it's probably a bug somewhere, and i'd rather eliminate the bug cases before turning it off.
