--- Comment #2 from Reid Kleckner <r...@google.com> ---
r319490 was not reverted, so this is fixed. Now we get XOR RSP instructions as
expected:

$ clang-cl -O2 -GS t2.c -Fat.s -c && grep -B1 -A2 security t.s
        .seh_endprologue
        movq    __security_cookie(%rip), %rax
        xorq    %rsp, %rax
        movq    %rax, 96(%rsp)
--
        xorq    %rsp, %rcx
        callq   __security_check_cookie
        nop
        addq    $104, %rsp
