The PR98481 fix corrects an ABI regression in GCC 10, but we don't want to introduce an ABI change in the middle of the GCC 10 cycle. This patch introduces ABI v15 for the fix, which will be available but not default in GCC 10.3; the broken behavior remains in ABI v14. Compatibility aliases will not be generated for this change. gcc/ChangeLog: PR c++/98481 * common.opt: Document v15 and v16. gcc/c-family/ChangeLog: PR c++/98481 * c-opts.c (c_common_post_options): Bump latest_abi_version. gcc/cp/ChangeLog: PR c++/98481 * mangle.c (write_expression): Adjust. * class.c (find_abi_tags_r): Disable PR98481 fix for ABI v14. (mark_abi_tags_r): Likewise. gcc/testsuite/ChangeLog: PR c++/98481 * g++.dg/abi/abi-tag24a.C: New test. * g++.dg/abi/macro0.C: Adjust expected value. |

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.
