* lavc: add a null bitstream filterAnton Khirnov2016-12-14
| | | | | | It is useful for testing/debugging and will also be used as the default filter in the following commit adding pre-decode filtering to avoid having a separate non-filtered codepath.

* build: Use _extralibs variable names instead of _libs everywhereDiego Biurrun2016-12-09
| | | | This makes naming more consistent and simplifies extralibs-related changes.
* build: Rename host_libs/HOSTLIBS variables to host_extralibs/HOSTEXTRALIBSDiego Biurrun2016-12-09

* compat/atomics: add typecasts in atomic_compare_exchange_strong()Wan-Teh Chang2016-12-08
| | | | | | | | | | | | | | | | | | | | | The Solaris and Windows emulations of atomic_compare_exchange_strong() need typecasts to avoid compiler warnings, because the functions they call expect a void* pointer but an intptr_t integer is passed. Note that the emulations of atomic_compare_exchange_strong() (except the gcc version) only work for atomic_intptr_t because of the type of the second argument (|expected|). See http://en.cppreference.com/w/c/atomic: _Bool atomic_compare_exchange_strong( volatile A* obj, C* expected, C desired ); The types of the first argument and second argument are different (|A| and |C|, respectively). |C| is the non-atomic type corresponding to |A|. In the emulations of atomic_compare_exchange_strong(), |C| is intptr_t. This implies |A| can only be sig_intptr_t. Signed-off-by: Wan-Teh Chang <wtc@google.com>
* avutil: fix data race in av_get_cpu_flags()Wan-Teh Chang2016-12-08
| | | | | | | | | | | | | | | | | | | | | | | | Make the one-time initialization in av_get_cpu_flags() thread-safe. The static variables |flags|, |cpuflags_mask|, and |checked| in libavutil/cpu.c are read and written using normal load and store operations. These are considered as data races. The fix is to use atomic load and store operations. Remove the |checked| variable because the invalid value of -1 for |flags| can be used to indicate the same condition. Rename |flags| to |cpu_flags| and move it to file scope. The fix can be verified by running the libavutil/tests/cpu_init.c test program under ThreadSanitizer: ./configure --toolchain=clang-tsan make libavutil/tests/cpu_init libavutil/tests/cpu_init There should be no warnings from ThreadSanitizer.

* configure: add -fPIE instead of -pie to C flags for ThreadSanitizerWan-Teh Chang2016-12-06
| | | | | | | | | | | | | | | | | | | | | | | -pie was added to C flags for ThreadSanitizer in commit 19f251a2882a8d0779b432e63bf282e4d9c443bb. Under clang 3.8.0, the -pie flag causes a compiler warning and a linker error when running configure --toolchain=clang-tsan. Here is an excerpt from config.log: clang ... -fsanitize=thread -pie -std=c11 -fomit-frame-pointer -pthread -c -o /tmp/ffconf.A8SsaoCF.o /tmp/ffconf.JdpujQlD.c clang: warning: argument unused during compilation: '-pie' clang -fsanitize=thread -pie -Wl,--as-needed -o /tmp/ffconf.2iYA4bsw /tmp/ffconf.A8SsaoCF.o -lm -lm -lbz2 -lz -pthread /usr/bin/ld: /tmp/ffconf.A8SsaoCF.o: relocation R_X86_64_PC32 against undefined symbol `atan2f@@GLIBC_2.2.5' can not be used when making a shared object; recompile with -fPIC /usr/bin/ld: final link failed: Bad value clang: error: linker command failed with exit code 1 (use -v to see invocation) To be conservative, I changed -pie to -fPIE. But the documentation seems to imply just -fsanitize=thread is enough: http://clang.llvm.org/docs/ThreadSanitizer.html https://github.com/google/sanitizers/wiki/ThreadSanitizerCppManual Signed-off-by: Wan-Teh Chang <wtc@google.com> Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* configure: Pass CFLAGS_HEADERS through the right CFLAGS filterDiego Biurrun2016-12-06
| | | | | The generic parameter names used for CFLAGS in configure must be filtered for each compiler and replaced by the equivalent flag for that compiler.

* configure: Simplify OMX checkDiego Biurrun2016-12-06

* configure: Move COMPONENT_LIST to the bottom of CONFIG_LISTDiego Biurrun2016-12-06
| | | | | This ensures that dependencies are resolved correctly. COMPONENT_LIST can contain parts that depend on previous entries of CONFIG_LIST.
