GCC modified for the FreeChainXenon project
37edf28c24
For a span with statically empty extent, we currently model the preconditions of front(), back(), and operator[] as if they are mandates, by using a static_assert to verify that extent != 0. This causes us to reject valid programs that would instantiate these member functions and at runtime never call them. Since they are already followed by more general runtime asserts, this patch just removes these static_asserts altogether, libstdc++-v3/ChangeLog: * include/std/span (span::front): Remove static_assert. (span::back): Likewise. (span::operator[]): Likewise. * testsuite/23_containers/span/back_neg.cc: Rewrite to verify that we check the preconditions of back() only when it's called. * testsuite/23_containers/span/front_neg.cc: Likewise for front(). * testsuite/23_containers/span/index_op_neg.cc: Likewise for operator[]. |

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.
