Subject: [PATCH] libunwind: don't mess around with ARM atomic detection
Date: Wed, 7 Jun 2017 15:40:06 +0100 [thread overview]
Message-ID: <1496846406-18518-1-git-send-email-ross.burton@intel.com> (raw)
This recipe explictly sets -DAO_USE_PTHREAD_DEFS on ARM, but with libunwind 1.2
this causes the linker to fail:
hidden symbol `__sync_synchronize' in libgcc.a(linux-atomic.o) is referenced by DSO
Removing these defines lets configure do the right thing and build libunwind.
