Subject: [Buildroot] [git commit branch/2019.11.x] package/grpc: add workaround for gcc<5
Date: Sun, 12 Jan 2020 11:09:14 +0100 [thread overview]
Message-ID: <20200112102020.8DE918B458@busybox.osuosl.org> (raw)

http://autobuild.buildroot.net/results/3d5/3d5e0b2b8c6670cf9a43ceac4b8173760e1f933c/
Commit e0e54afd0cf7 (package/grpc: bump to version 1.25.0) bumped the grpc
version and added a workaround for 'failure memory model cannot be stronger
than success memory model for '__atomic_compare_exchange'. This workaround
is also needed for 1.23.0, so add it here as well.
