This fixes a weakness in the way -fdump-ada-spec builds names for anonymous structures in the C/C++ code, resulting in duplicate identifiers under specific circumstances. c-family/ * c-ada-spec.c: Include bitmap.h. (dump_ada_double_name): Rename into... (dump_anonymous_type_name): ...this. Always use the TYPE_UID. (dump_ada_array_type): Adjust to above renaming. Robustify. (dump_nested_types_1): New function copied from... Add dumped_types parameter and pass it down to dump_nested_type. (dump_nested_types): ...this. Remove parent parameter. Just call dump_nested_types_1 on an automatic bitmap. (dump_nested_type): Add dumped_types parameter. <ARRAY_TYPE>: Do not dump it if already present in dumped_types. Adjust recursive calls and adjust to above renaming. (dump_ada_declaration): Adjust call to dump_nested_types. Tidy up and adjust to above renaming. (dump_ada_specs): Initialize and release bitmap obstack.
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.
