GCC modified for the FreeChainXenon project

The problem here is that first check_initializer calls build_aggr_init_full_exprs, which does overload resolution, but then in the case of failed constexpr throws away the result and does it again in build_functional_cast. But in the first overload resolution, reshape_init_array_1 decided to reuse the inner CONSTRUCTORs because tf_error is set, so we know we're committed. But the second pass gets confused by the CONSTRUCTORs with non-init-list types. Fixed by avoiding a second pass: instead, pass the call from build_aggr_init to build_cplus_new, which will turn it into a TARGET_EXPR. I don't bother to change the object argument because it will be replaced later in simplify_aggr_init_expr. PR c++/102307 gcc/cp/ChangeLog: * decl.cc (check_initializer): Use build_cplus_new in case of constexpr failure. gcc/testsuite/ChangeLog: * g++.dg/cpp1z/constexpr-array2.C: New test. |

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.
