I appreciate it is quite late in the day for the 4.9.3 branch, but do we want to consider this patch for backporting (either now or after the branch reopens)? gcc.dg/atomic/c11-atomic-exec-5.c is the only interesting test I see failing on a native AArch64 build of the 4.9.3 release candidate (there is plenty of other FAILures, but they are guality, scan assembler or missed optimization fails). Thanks, James
