--- Comment #13 from Richard Biener <rguenth at gcc dot gnu.org> --- Ah. Setting value number of t34_9752(D) to t34_9752(D) (changed) Setting value number of t42_9760(D) to t42_9760(D) (changed) WARNING: Giving up with SCCVN due to SCC size 10003 exceeding 10000 so we're failing to call scc_vn_restore_ssa_info when we fail this way. oops.
