[v3] __native_type typedefs, condition_variable, typesize
- From: Benjamin Kosnik <bkoz at redhat dot com>
- To: gcc-patches at gcc dot gnu dot org, libstdc++ at gcc dot gnu dot org

- Subject: [v3] __native_type typedefs, condition_variable, typesize
Adds consistent private __native_type typedefs for
mutex/condition_variable, makes the current ones private.
For std::condition_variable, there is an extra mutex data object that is
superfluous, as it is used only in notify_one/notify_all member
functions, which call pthread_cond_signal/broadcast, which do not need
to be locked. So, removed.
Adds some type/native_type compares to the testsuite.

2009-02-09 Benjamin Kosnik <bkoz@redhat.com>
* include/std/condition_variable (condition_variable): Remove
_M_internal_mutex. Add private __native_type typedef.
* src/condition_variable.cc (condition_variable::notify_one):
Remove _M_internal_mutex use. Use typedef.
(condition_variable::notify_all): Same.
* include/std/mutex (mutex): Add private __native_type typedef. Use it.
(recursive_mutex): Same.
(timed_mutex): Same.
(recursive_timed_mutex): Same.
(once_flag): Make __native_type typedef private.
* include/std/thread (this_thread): Add minimal markup.

Adjust line numbers.
