From: Marek Polacek <mpolacek@gcc.gnu.org> To: gcc-cvs@gcc.gnu.org Subject: [gcc r13-4470] testsuite: Adjust dg-error for -fimplicit-constexpr Date: Fri, 2 Dec 2022 20:07:52 +0000 (GMT) [thread overview] Message-ID: <20221202200752.B33263858D39@sourceware.org> (raw) https://gcc.gnu.org/g:1998db0fa1f78e373c88daea8bb339d32b41e6aa commit r13-4470-g1998db0fa1f78e373c88daea8bb339d32b41e6aa Author: Marek Polacek <polacek@redhat.com> Date: Fri Dec 2 14:43:26 2022 -0500 testsuite: Adjust dg-error for -fimplicit-constexpr Some of the new tests were failing with -fimplicit-constexpr. This patch adjusts the expected diagnostic. Tested with GXX_TESTSUITE_STDS=98,11,14,17,20,23 make check-c++ RUNTESTFLAGS="--target_board=unix\{,-fimplicit-constexpr\} dg.exp=spaceship-eq3.C" gcc/testsuite/ChangeLog: * g++.dg/cpp0x/constexpr-ex1.C: Adjust dg-error. * g++.dg/cpp23/constexpr-nonlit10.C: Adjust dg-warning. * g++.dg/cpp23/constexpr-nonlit11.C: Likewise. * g++.dg/cpp2a/spaceship-eq3.C: Add dg-error.
