This patch renames symbols that happen to have names which are reserved keywords in C++. Most of this was generated with Tromey's cxx-conversion.el script. Some places where later hand massaged a bit, to fix formatting, etc. And this was rebased several times meanwhile, along with re-running the script, so re-running the script from scratch probably does not result in the exact same output. I don't think that matters anyway. gdb/ 2015-02-27 Tom Tromey <tromey@redhat.com> Pedro Alves <palves@redhat.com> Rename symbols whose names are reserved C++ keywords throughout. gdb/gdbserver/ 2015-02-27 Tom Tromey <tromey@redhat.com> Pedro Alves <palves@redhat.com> Rename symbols whose names are reserved C++ keywords throughout.
