During the implementation of modules I added myself a note to implement nested_udt handling. It wasn't obvious to me what they were for and nothing seemed to be broken in ignoring them. I figured something would eventually pop up and I'd add support. Nothing popped up. Investigating on trunk discovered 3 places where we look at the nested-udts. I couldn't figure how the one in lookup_field_r was needed -- surely the regular lookup would find the type. It turned out that code was unreachable. So we can delete it. Next in do_type_instantiation, we walk the nested-utd table instantiating types. But those types are also on the TYPE_FIELDS list, which we've just iterated over. So I can move the handling into that loop. The final use is in handling structs that have a typedef name for linkage purposes. Again, we can just iterate over TYPE_FIELDS. (As commented, we probably don't need to do even that, as a DR, whose number I forget, requires such structs to only have C-like things in them. But I didn't go that far. Having removed all the uses of nested-udts, I can remove their creation from name-lookup, and as the only instance of a binding_table object, we can remove all that code too. gcc/cp/ * cp-tree.h (struct lang_type): Delete nested_udts field.

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.
