Hi
Here is the patch to registers Printers depending on activation of
versioned namespace.
2017-04-27 François Dumont <fdum...@gcc.gnu.org>
* python/Makefile.am [ENABLE_SYMVERS_GNU_NAMESPACE]
(user_versioned_namespace): New.
(gdb.py): Adapt target.
* python/Makefile.in: Regenerate.
* python/hook.in: Likewise.
* python/libstdcxx/v6/printers.py (add_one_template_type_printer):
Register only 1 Printer type depending on _versioned_namespace value.
(add_one_type_printer): Likewise.
(register_libstdcxx_printers): Add parameter use_versioned_namespace.
Adapt _versioned_namespace value based on it.
* testsuite/lib/gdb-test.exp (get_use_versioned_namespace): New.
(note-test): Detect if version namespace is active and pass the
information to register_libstdcxx_printers.
* testsuite/libstdc++-prettyprinters/48362.cc: Replace a regexp-test
by a note-test.
Tested under Linux x86_64, with and without version namespace.
Ok to commit to trunk ?
What's the advantage?
Again, the point of my patch was to optimise if needed. Is it needed?
Oh, I thought it was obviously better to not register useless Printers.
But if you need a bug report or an explicit test showing that it is
better then I don't have it. Maybe a gdb guy could tell us if it worth it.
Do I just keep the small cleanup on the useless usage of regexp-test in
48362.cc ?
Are we going to wait for gcc 7.1 before bumping version namespace ?
Shouldn't we wait until we change something that would require bumping
it? :-)
Ok, I'll add it to my first patch needing it.
Is it the right moment to do so ?
