gthr-posix.h (__gthread_cond_broadcast, [...]): Add to extend interface for POSIX conditional variables.
2007-09-13 Doug Kwan <dougkwan@google.com>
* gcc/gthr-posix.h (__gthread_cond_broadcast, __gthread_cond_wait,
__gthread_cond_wait_recursive): Add to extend interface for POSIX
conditional variables. (__GTHREAD_HAS_COND): Macro defined to signify
support of conditional variables.
* gcc/gthr-posix95.h (__gthread_cond_broadcast, __gthread_cond_wait,
__gthread_cond_wait_recursive): Add to extend interface for POSIX
conditional variables. (__GTHREAD_HAS_COND): Macro defined to signify
support of conditional variables.
* gcc/gthr-single.h (__gthread_cond_broadcast, __gthread_cond_wait,
__gthread_cond_wait_recursive): Add to extend interface for POSIX
conditional variables.
* gcc/gthr.h: Update comments to document new interface.
* libstdc++-v3/include/ext/concurrent.h (class __mutex,
class __recursive_mutex): Add new method gthread_mutex to access
inner gthread mutex.
[__GTHREAD_HAS_COND] (class __concurrence_broadcast_error,
class __concurrence_wait_error, class __cond): Add.
* guard.cc (recursive_push, recursive_pop): Delete.
(init_in_progress_flag, set_init_in_progress_flag): Add to
replace recursive_push and recursive_pop.
(throw_recursive_init_exception): Add.
(acquire, __cxa_guard_acquire, __cxa_guard_abort and
__cxa_guard_release): [__GTHREAD_HAS_COND] Use a conditional
for synchronization of static variable initialization.
The global mutex is only held briefly when guards are
accessed. [!__GTHREAD_HAS_COND] Fall back to the old code,
which deadlocks.
* testsuite/thread/guard.cc: Add new test. It deadlocks with the
old locking code in libstdc++-v3/libsup++/guard.cc.

libpthread libraries. We also need a test that works for archive

|

libraries. We can't use pthread_once as some libc versions call the
|
|
|
|
init function. We also can't use pthread_create or pthread_attr_init
|
|
|
|
as these create a thread and thereby prevent changing the default stack
|
|
|
|
size. The function pthread_default_stacksize_np is available in both
|
|
|
|
the archive and shared versions of libpthread. It can be used to
|

|
|
determine the default pthread stack size. There is a stub in some
|
|
|
|
shared libc versions which returns a zero size if pthreads are not

active. We provide an equivalent stub to handle cases where libc

doesn't provide one. */

gthr-posix.h (__gthread_cond_broadcast, [...]): Add to extend interface for POSIX conditional variables.
2007-09-13 Doug Kwan <dougkwan@google.com>

* libstdc++-v3/include/ext/concurrent.h (class __mutex,

inner gthread mutex.
[__GTHREAD_HAS_COND] (class __concurrence_broadcast_error,

* guard.cc (recursive_push, recursive_pop): Delete.

old locking code in libstdc++-v3/libsup++/guard.cc.

gthr-posix.h (__gthread_cond_broadcast, [...]): Add to extend interface for POSIX conditional variables.
2007-09-13 Doug Kwan <dougkwan@google.com>
* gcc/gthr-posix.h (__gthread_cond_broadcast, __gthread_cond_wait,
__gthread_cond_wait_recursive): Add to extend interface for POSIX
conditional variables. (__GTHREAD_HAS_COND): Macro defined to signify
support of conditional variables.
* gcc/gthr-posix95.h (__gthread_cond_broadcast, __gthread_cond_wait,
__gthread_cond_wait_recursive): Add to extend interface for POSIX
conditional variables. (__GTHREAD_HAS_COND): Macro defined to signify
support of conditional variables.
* gcc/gthr-single.h (__gthread_cond_broadcast, __gthread_cond_wait,
__gthread_cond_wait_recursive): Add to extend interface for POSIX
conditional variables.
* gcc/gthr.h: Update comments to document new interface.
* libstdc++-v3/include/ext/concurrent.h (class __mutex,
class __recursive_mutex): Add new method gthread_mutex to access
inner gthread mutex.
[__GTHREAD_HAS_COND] (class __concurrence_broadcast_error,
class __concurrence_wait_error, class __cond): Add.
* guard.cc (recursive_push, recursive_pop): Delete.
(init_in_progress_flag, set_init_in_progress_flag): Add to
replace recursive_push and recursive_pop.
(throw_recursive_init_exception): Add.
(acquire, __cxa_guard_acquire, __cxa_guard_abort and
__cxa_guard_release): [__GTHREAD_HAS_COND] Use a conditional
for synchronization of static variable initialization.
The global mutex is only held briefly when guards are
accessed. [!__GTHREAD_HAS_COND] Fall back to the old code,
which deadlocks.
* testsuite/thread/guard.cc: Add new test. It deadlocks with the
old locking code in libstdc++-v3/libsup++/guard.cc.
