Currently the streaming code uses TREE_CONSTANT to determine whether an entity will have a definition that is interesting to stream out. This is not sufficient, however; we also need to write the definition of references, since although not TREE_CONSTANT they can still be usable in constant expressions. As such this patch uses the existing decl_maybe_constant_var function which correctly handles this case. gcc/cp/ChangeLog: * module.cc (has_definition): Use decl_maybe_constant_var instead of TREE_CONSTANT. gcc/testsuite/ChangeLog: * g++.dg/modules/cexpr-5_a.C: New test. * g++.dg/modules/cexpr-5_b.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.
