--- Comment #16 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The trunk branch has been updated by Jason Merrill <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:958940eb3511e341e57606f5a2f5399bc89533cb commit r14-6506-g958940eb3511e341e57606f5a2f5399bc89533cb Author: Jason Merrill <ja...@redhat.com> Date: Tue Dec 12 22:53:10 2023 -0500 c++: constant direct-initialization [PR108243] When testing the proposed patch for PR71093 I noticed that it changed the diagnostic for consteval-prop6.C. I then noticed that the diagnostic wasn't very helpful either way; it was complaining about modification of the 'x' variable, but it's not a problem to initialize a local variable with a consteval constructor as long as the value is actually constant, we want to know why the value isn't constant. And then it turned out that this also fixed a missed-optimization bug in the testsuite. PR c++/108243 gcc/cp/ChangeLog: * constexpr.cc (cxx_eval_outermost_constant_expr): Turn a constructor CALL_EXPR into a TARGET_EXPR. gcc/testsuite/ChangeLog: * g++.dg/cpp2a/consteval-prop6.C: Adjust diagnostic. * g++.dg/opt/is_constant_evaluated3.C: Remove xfails.
