-Subject: [PATCH] wscript: improve stdatomic check
-
-The current stdatomic check verifies the availability of the function by
-calling atomic_load(). It also uses this test to check if linking
-against libatomic is needed or not.
-
-Unfortunately, on specific architectures (namely SPARC), using
-atomic_load() does *not* require linking against libatomic, while other
-atomic operations do. Due to this, mpv's wscript concludes that
-stdatomic is available, and that linking against libatomic is not
-needed, causing the following link failure:
-
-[190/190] Linking build/mpv
-audio/out/ao.c.13.o: In function `ao_query_and_reset_events':
-/home/peko/autobuild/instance-0/output/build/mpv-0.18.1/build/../audio/out/ao.c:399: undefined reference to `__atomic_fetch_and_4'
-
-In order to fix this, the stdatomic check is adjusted to call
-atomic_fetch_add() instead, which does require libatomic. Thanks to
-this, the wscript realizes that linking against libatomic is needed, and
-the build works fine.
