--- Comment #11 from Jeffrey A. Law <law at redhat dot com> ---
The PRE/GCSE limits were changed between gcc-5 and gcc-6 to allow it to run on
larger CFGs such as this, but without totally blowing up.  So I don't consider
the PRE/GCSE bump a regression, a conscious decision to try harder to optimize
functions with these painful CFGs.
