When printing the substituted parameter list of a requires-expression as part of the "in requirements with ..." context line during concepts diagnostics, we weren't considering that substitution into a parameter pack can yield zero or multiple parameters. This patch changes the way we print the parameter list of a requires-expression in print_requires_expression_info. We now print the dependent form of the parameter list (along with its template parameter mapping) instead of printing its substituted form. Besides being an improvement in its own, this also sidesteps the substitution issue in the PR altogether. gcc/cp/ChangeLog: PR c++/94808 * error.c (print_requires_expression_info): Print the dependent form of the parameter list with its template parameter mapping, rather than printing the substituted form. gcc/testsuite/ChangeLog: PR c++/94808 * g++.dg/concepts/diagnostic12.C: New test. * g++.dg/concepts/diagnostic5.C: Adjust dg-message.
This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
