<pre>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</pre>
