build_noexcept_spec refrained from resolving nondependent noexcept expressions when they were not part of the function types (C++ 11 and 14). This caused problems during mangling: canonical_eh_spec, when called on the template function type, would find an unresolved but not explicitly deferred expression, and nothrow_spec_p would reject it. We could relax the mangling logic to skip canonical_eh_spec, but since -Wnoexcept-type warns when mangling function names that change as noexcept specs become part of types and of mangling in C++17, and the test at mangling time may give incorrect results if the spec is not resolved, we might as well keep things simple and resolve nondependent noexcept specs sooner rather than later. This is what this patch does. for gcc/cp/ChangeLog PR c++/86397 * except.c (build_noexcept_spec): Resolve nondependent expressions. for gcc/testsuite/ChangeLog PR c++/86397 * g++.dg/cpp0x/pr86397-1.C: New. * g++.dg/cpp0x/pr86397-2.C: New.

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.
