* Source/cmake/OptionsWPE.cmake:
Enable THREADS_PREFER_PTHREAD_FLAG. This uses -pthread instead of
-lpthread, fixing the 64-bit RISC-V build of the GTK+ port due to
missing atomic primitives.
* Source/cmake/WebKitCompilerFlags.cmake:
Move the test to detect whether we need to link against libatomic
to a common CMake file so it can be used from both JavaScriptCore
and WebKit.
Source/JavaScriptCore:
We were linking JavaScriptCore against libatomic in MIPS because
in that architecture __atomic_fetch_add_8() is not a compiler
intrinsic and is provided by that library instead. However other
architectures (e.g armel) are in the same situation, so we need a
generic test.
That test already exists in WebKit/CMakeLists.txt, so we just have
to move it to a common file (WebKitCompilerFlags.cmake) and use
its result (ATOMIC_INT64_REQUIRES_LIBATOMIC) here.
* CMakeLists.txt:
Source/WebKit:
Move the test to determine whether we need to link against
libatomic to the common file WebKitCompilerFlags.cmake so it can
also be used for JavaScriptCore.
