Subject: [PATCH] mesa: Add define to indicate missing 64bit atomics on armv5
Date: Tue, 6 Jun 2017 10:13:46 -0700 [thread overview]
Message-ID: <20170606171346.21413-1-raj.khem@gmail.com> (raw)
This is wrongly detected by configure since it only checks for
__sync_add_and_fetch and not __atomic_fetch_add, it decides
to let compiler emit references to atomic functions which
it expects to be provided by libgcc, but thats not the
case for armv5 arch
[YOCTO #11616]
