    Description

      Support for building with -moutline-atomcis was added in SERVER-51722 and backported to v4.4 and v4.2. However, we do not yet have a GCC 8 release which offers that flag. We will need to wait on GCC 8.5 and then upgrade the toolchain. Once that happens, the next releases from v4.4 and v4.2 will use the LSE support. Note that the upcoming v5.0 release will have the LSE intrinsics without needing to wait for a compiler upgrade, because it targets armv8.2-a by default.
