--- Comment #8 from Jan Hubicka <hubicka at gcc dot gnu.org> ---
So in mgau_eval the inner loop is vectorized and peeled, epilogues are
vectorized and fully unrolled. The resulting code seems bit more complicated
then it needs to be.
I do not think the problems in profile updates are very iportant and actually
should affect overall performance much.
vector_gautbl_eval_logs3 seems similar but we run out of registers, so there
profile may be more relevant
I added to PR110692 oversimplified example of this pattern. I think we could
get overall codegen better...
