-Subject: [PATCH] Add AO_REQUIRE_CAS to fix build on ARM < v6
-
-ARM earlier than ARMv6, such as ARMv4 and ARMv5 do not provide
-optimize atomic operations in libatomic_ops. Since libunwind is using
-such operations, it should define AO_REQUIRE_CAS before including
-<atomic_ops.h> so that libatomic_ops knows it should use emulated
-atomic operations instead (even though they are obviously a lot more
-expensive).
-
-Also, while real atomic operations are all inline functions and
-therefore linking against libatomic_ops was not required, the emulated
-atomic operations actually require linking against libatomic_ops, so
-the commented AC_CHECK_LIB test in acinclude.m4 is uncommented to make
-sure we link against libatomic_ops.
