* cp-tree.h (struct lang_decl_decomp): New type. (struct lang_decl): Add u.decomp. (LANG_DECL_DECOMP_CHECK): Define. (DECL_DECOMPOSITION_P): Note it is set also on the vars for user identifiers. (DECL_DECOMP_BASE): Define. (retrofit_lang_decl): Add extra int = 0 argument. * lex.c (retrofit_lang_decl): Add SEL argument, if non-zero use it to influence the selector choices and for selector 0 to non-zero transition copy old content. (cxx_dup_lang_specific_decl): Handle DECL_DECOMPOSITION_P. * decl.c (poplevel): For DECL_DECOMPOSITION_P, check !DECL_DECOMP_BASE instead of !DECL_VALUE_EXPR. Adjust warning wording if decl is a structured binding. (cp_finish_decomp): Pass 4 as the new argument to retrofit_lang_decl. Set DECL_DECOMP_BASE. Ignore DECL_READ_P sets from initialization of individual variables for tuple structured bindings. (grokdeclarator): Pass 4 as the new argument to retrofit_lang_decl. Clear DECL_DECOMP_BASE. * decl2.c (mark_used): Mark DECL_DECOMP_BASE TREE_USED as well. * pt.c (tsubst_decomp_names): Assert DECL_DECOMP_BASE matches what is expected. * expr.c (mark_exp_read): Recurse on DECL_DECOMP_BASE instead of DECL_VALUE_EXPR. * g++.dg/cpp1z/decomp29.C (p): New variable. (main): Add further tests. From-SVN: r248483 |

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.
