(I don't have an opinion on how to fix the issue, but) Are SYSREGS actually always 64 bits even on arm32, and these helpers just a shorthand for the lower 32 bits, or is this an effectively-unnecessary constraint imposed by Clang? ~Andrew _______________________________________________ Xen-devel mailing list Xen-devel@lists.xenproject.org https://lists.xenproject.org/mailman/listinfo/xen-devel
