N2557, accepted into C2x at the October WG14 meeting, removes the requirement that duplicates of standard attributes cannot appear within an attribute list (so allowing e.g. [[deprecated, deprecated]], where previously that was disallowed but [[deprecated]] [[deprecated]] was OK). Remove the code checking for this (standard attributes aren't in any released version of the C standard) and update tests accordingly. Bootstrapped with no regressions on x86_64-pc-linux-gnu. gcc/c/ 2020-10-27 Joseph Myers <joseph@codesourcery.com> * c-parser.c (c_parser_std_attribute_specifier): Allow duplicate standard attributes. gcc/testsuite/ 2020-10-27 Joseph Myers <joseph@codesourcery.com> * gcc.dg/c2x-attr-deprecated-4.c, gcc.dg/c2x-attr-fallthrough-4.c, gcc.dg/c2x-attr-maybe_unused-4.c: Allow duplicate attributes. |

README
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.
