When using minimal encodings, most artificial types do not need to have their names emitted in the DWARF. This patch changes the compiler to generally omit these names. However, a subset of names are needed: when the compiler creates an artificial type for certain kinds of arrays, the name is needed by gdb. So, a new parameter is added to create_type_decl to allow this omission to be disabled. Note that simply passing 'false' as the artificial_p argument to create_type_decl doesn't work properly -- other parts of the compiler seem to rely on this flag being set, and so making this change causes ICEs. gcc/ada/ChangeLog: * gcc-interface/decl.cc (gnat_to_gnu_entity): Update some calls to create_type_decl. * gcc-interface/gigi.h (create_type_decl): Add can_be_nameless parameter. * gcc-interface/utils.cc (create_type_decl): Add can_be_nameless parameter. Set DECL_NAMELESS on type decl. |

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.
