https://gcc.gnu.org/bugzilla/show_bug.cgi?id=79224 --- Comment #12 from Jan Hubicka --- I know - it is the problem I mentioned earlier. ray_sphere has a conditional on parameter SP that decides whether it does extra work. In some cases ray_sphere is called with SP NULL. Now we compute the speed

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=79224 --- Comment #11 from Richard Biener --- I still see inlining differences (comparing to GCC 6). The profile looks like 33.18% c-ray-f-7 c-ray-f-7 [.] shade 28.18% c-ray-f-6 c-ray-f-6 [.] shade 11.50% c-ray-f-7 c-ray-f

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=79224 --- Comment #9 from Jan Hubicka --- Most of the regression caused by the inlining difference is fixed now, but the solution is not ideal. According to Czerny we still have quite noticeable regression https://gcc.opensuse.org/c++bench-czerny/c-ray

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=79224 --- Comment #5 from Jan Hubicka --- The issue is that we no longer inline all calls to ray_sphere which is the inlining that matters. Declaring trace noinline or ray_sphere always_inline helps.
