    arm64: Work around a clang/LLVM misoptimization · 12e0c905
    Martin Storsjö authored
    This avoids a misoptimization in clang,
    https://bugs.llvm.org/show_bug.cgi?id=39550, where the root cause
    has been around for a number of years, but a change in LLVM 6.0
    allowed for better optimizations, exposing this bug. This bug is
    on good track to be fixed in LLVM for the 8.0 release and hopefully
    also for backporting into 7.0.1. It is however present in 6.0, 6.0.1
    and 7.0, and other downstream users such as Xcode 10.0/10.1.
