* Allow static C++ destructors to be properly called on dlclose().David 'Digit' Turner2010-06-183-7/+13
| | | | | | | | | | | | | | | | | | | | | | | With this patch, _and_ an upcoming build/ patch, the destruction of static C++ objects contained in shared libraries will happen properly when dlclose() is called. Note that this change introduces crtbegin_so.S and crtend_so.S which are currently ignored by the build system. + move definition of __dso_handle to the right place (before that, all shared libraries used the __dso_handle global variable from the C library). Note that we keep a 'weak' __dso_handle in aeabi.c to avoid breaking the build until the next patch to build/core/combo/ appears. We will be able to remove that later. + move bionic/aeabi.c to arch-arm/bionic/ (its proper location) Change-Id: Ie771aa204e3acbdf02fd30ebd4150373a1398f39 NOTE: The NDK will need to be modified to enable this feature in the shared libraries that are generated through it.

| | | | | | | | | | | | | | | | | | | | This does not change the implementation of conditional variables since we're waiting for other system components to properly use pthread_condattr_init/setpshared before that. Also remove an obsolete x86 source file. Change-Id: Ia3e3fbac35b87a534fb04d4381c3c66b975bc8f7

* | bionic: pthread: use private futexes by default for mutexes and condvarsDavid 'Digit' Turner2010-03-111-0/+37
| | | | | | | | | | | | | | | | | | | | Private futexes are a recent kernel addition: faster futexes that cannot be shared between processes. This patch uses them by default, unless the PROCESS_SHARED attribute flag is used when creating a mutex and/or conditional variable. Also introduces pthread_condattr_init/destroy/setpshared/getpshared. Change-Id: I3a0e2116f467072b046524cb5babc00e41057a53

* Fix the C library initialization to avoid calling static C++ constructors twice.David 'Digit' Turner2009-06-022-18/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | The problem was due to the fact that, in the case of dynamic executables, the dynamic linker calls the DT_PREINIT_ARRAY, DT_INIT and DT_INIT_ARRAY constructors when loading shared libraries and dynamic executables, *before* calling the executable's entry point (i.e. arch-$ARCH/bionic/crtbegin_dynamic.c) which in turns call __libc_init() in libc.so, as defined by bionic/libc_init_dynamic.c The latter did call these constructors array again, mistakenly. The patch also updates the documentation of many related functions. Also adds a new section to linker/README.TXT explaining restrictions on C library usage. The patch has been tested on a Dream for stability issues with proprietary blobs: - H264 decoding works - Camera + Video recording works - GPS works - Sensors work The tests in system/extra/tests/bionic/libc/common/test_static_cpp_mutex.cpp has been run and shows the static C++ constructor being called only once.
