--- Comment #3 from Jan Hubicka <hubicka at gcc dot gnu.org> --- tp_sum is function that should be inlined. The problem is that its estimated size after inlining a function call within tp_sum is 75. We used to estimate that the speedup for inlining function is large and thus we bumped limit from 30 to 400 (inline-insns-sinle to -auto). This is no longer the case after fix to the time acocunting, because tp_sum has loop which we now account as iterating 16 times (it is correct) and previously we accounted 1 times (that is bug I fixed). Now the speedup for inlining estimated by inliner is just about 2% which falls bellow to the estimate of 15%. I do not see how to reasonably tel inliner that this is good idea to inline here. So shall we just xfail the testcase? Honza
