--- Comment #3 from Hans-Peter Nilsson <hp at gcc dot gnu.org> ---
There's one single regression event, bringing the host runtime to about 1.63
seconds. Then some time later, an additional 0.1 second was added
(accumulated).
I did not look into that latter regression. The big one is clouded by a large
range of commits where max_size_type failed, due to r14-159-g03cebd304955a6.
This was fixed in r14-205-g83470a5cd4c3d2, at which time there the big
regression is seen for the first time. That is also the "cause" for the
commit, because applying that commit to r14-158-g7d115e01411156 shows the same
number as for r14-205-g83470a5cd4c3d2.
Actually, it's the testsuite part of that patch, because with that reverted the
execution time backs down to 0.33 seconds. IOW, this while PR is /testsuites.
Not sure what to do to improve the execution time, as plain disabling the using
"signed_rep_t = __int128;" by making the first line "+#if 0 &&
__SIZEOF_INT128__" yields
/x/testsuite/std/ranges/iota/max_size_type.cc:36: note: the comparison reduces
to '(16 == 8)'
Maybe the higher number for the execution time is actually the "right" one and
the range should be cut down to -100..100 for *all* targets?
HNY!
