--- Comment #6 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Simon Martin <simar...@gcc.gnu.org>: https://gcc.gnu.org/g:02dff52c60e5b89d290147f142f655c7817154c2 commit r15-3232-g02dff52c60e5b89d290147f142f655c7817154c2 Author: Simon Martin <si...@nasilyan.com> Date: Mon Aug 26 14:09:46 2024 +0200 c++: Don't show constructor internal name in error message [PR105483] We mention 'X::__ct' instead of 'X::X' in the "names the constructor, not the type" error for this invalid code: === cut here === struct X {}; void g () { X::X x; } === cut here === The problem is that we use %<%T::%D%> to build the error message, while %qE does exactly what we need since we have DECL_CONSTRUCTOR_P. This is what this patch does. It also skips until the end of the statement and returns error_mark_node for this and the preceding if block, to avoid emitting extra (useless) errors. PR c++/105483 gcc/cp/ChangeLog: * parser.cc (cp_parser_expression_statement): Use %qE instead of incorrect %<%T::%D%>. Skip to end of statement and return error_mark_node in case of error. gcc/testsuite/ChangeLog: * g++.dg/parse/error36.C: Adjust test expectation. * g++.dg/tc1/dr147.C: Likewise. * g++.old-deja/g++.other/typename1.C: Likewise. * g++.dg/diagnostic/pr105483.C: New test.
