This corrects the earlier problems with removing the template header from local omp reductions. And it uncovered a latent bug. When we tsubst such a decl, we immediately tsubst its body. cp_check_omp_declare_reduction gets a success return value to gate that instantiation. udr-2.C got a further error, as the omp checking machinery doesn't appear to turn the reduction into an error mark when failing. I didn't dig into that further. udr-3.C appears to have been invalid and accidentally worked. gcc/cp/ * cp-tree.h (cp_check_omp_declare_reduction): Return bool. * semantics.c (cp_check_omp_declare_reduction): Return true on for success. * pt.c (push_template_decl_real): OMP reductions do not get a template header. (tsubst_function_decl): Remove special casing for local decl omp reductions. (tsubst_expr): Call instantiate_body for a local omp reduction. (instantiate_body): Add nested_p parm, and deal with such instantiations. (instantiate_decl): Reject FUNCTION_SCOPE entities, adjust instantiate_body call. gcc/testsuite/ * g++.dg/gomp/udr-2.C: Add additional expected error. libgomp/ * testsuite/libgomp.c++/udr-3.C: Add missing ctor. |

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.
