--- Comment #6 from Andrew Pinski <pinskia at gcc dot gnu.org> --- (In reply to Hwang Joonhyung from comment #0) > It took more than 30 minutes when I compiled testcase.cc with g++ 14.0.0 > 20231001 on Debian GNU/Linux 12 with -std=gnu++2a (or gnu++20, c++2a, c++20). > I guess it is a regression because it finishes within 0.1 second with g++ > 13.2.0 or 12.3.0. > The testcase is based on GetOneCharToken() of V8. Does -fno-checking solve the performance issue?
