This patch fixes PR c++/16117. gdb has an extension so that users can use expressions like FILE::NAME to choose a variable of the given name from the given file. The bug is that this extension takes precedence over ordinary C++ expressions of the same form. You might think this is merely hypothetical, but now that C++ headers commonly do not use an extension, it is more common. This patch fixes the bug by making two related changes. First, it changes gdb to prefer the ordinary C++ meaning of a symbol over the extended meaning. Second, it arranges for single-quoting of the symbol to indicate a preference for the extension. Built and regtested on x86-64 Fedora 18. New test case included. 2013-11-15 Tom Tromey <tromey@redhat.com> PR c++/16117: * c-exp.y (lex_one_token): Add "is_quoted_name" argument. (classify_name): Likewise. Prefer a field of "this" over a filename. (classify_inner_name, yylex): Update. 2013-11-15 Tom Tromey <tromey@redhat.com> * gdb.texinfo (Variables): Note gdb rules for ambiguous cases. Add example. 2013-11-15 Tom Tromey <tromey@redhat.com> * gdb.cp/includefile: New file. * gdb.cp/filename.exp: New file. * gdb.cp/filename.cc: New file.
