This patch changes the mangling of __alignof__ to v111__alignof__, making its mangling distinct from that of alignof(type) and alignof(expr). How we mangle ALIGNOF_EXPR now depends on its ALIGNOF_EXPR_STD_P flag, which after the previous patch gets consistently set for alignof(type) as well as alignof(expr). gcc/c-family/ChangeLog: PR c++/88115 * c-opts.c (c_common_post_options): Update latest_abi_version. gcc/ChangeLog: PR c++/88115 * common.opt (-fabi-version): Document =15. * doc/invoke.texi (C++ Dialect Options): Likewise. gcc/cp/ChangeLog: PR c++/88115 * mangle.c (write_expression): Mangle __alignof_ differently from alignof when the ABI version is at least 15. libiberty/ChangeLog: PR c++/88115 * cp-demangle.c (d_print_comp_inner) <case DEMANGLE_COMPONENT_EXTENDED_OPERATOR>: Don't print the "operator " prefix for __alignof__. <case DEMANGLE_COMPONENT_UNARY>: Always print parens around the operand of __alignof__. * testsuite/demangle-expected: Test demangling for __alignof__. gcc/testsuite/ChangeLog: PR c++/88115 * g++.dg/abi/macro0.C: Adjust. * g++.dg/cpp0x/alignof7.C: New test. * g++.dg/cpp0x/alignof8.C: New test. |

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.
