Richard Biener <rguenth at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Last reconfirmed|2009-11-03 12:18:41 |2024-2-20 --- Comment #11 from Richard Biener <rguenth at gcc dot gnu.org> --- GCC 14 shows, at -O2 with LIM4/RBR4 (the testcases setting) 0.55user 0.18system 0:00.73elapsed 100%CPU (0avgtext+0avgdata 798332maxresident)k 0inputs+8outputs (0major+195627minor)pagefaults 0swaps and with LIM5/RBR5 it blows 64GB. So here's LIM3/RBR3 as comparison: 0.00user 0.02system 0:00.38elapsed 8%CPU (0avgtext+0avgdata 30988maxresident)k 53680inputs+104outputs (74major+3608minor)pagefaults 0swaps re-confirmed and it's the original issue still, though the implementation detail of record_alias_subset rather record_component_aliases. record_alias_subset records childrens of the subset as immediate subset transitively.
