--- Comment #8 from Tobias Burnus <burnus at gcc dot gnu.org> 2010-09-28 14:57:34 UTC --- Using -fno-inline-functions, the program recovers the speed of the no-LTO version. Notes from #gcc: (dominiq) For fatigue the key for speed-up is inlining of generalized_hookes_law and you need -finline-limit=400 (richi) "Considering inline candidate generalized_hookes_law." / "Inlining failed: --param max-inline-insns-auto limit reached"
