[PATCH] D60039: Fix the bug of garbage collection of siod.

[Craig Topper via Phabricator via llvm-commits]

craig.topper added a comment.

I believe this is saving rbp but mangling it while doing so in a reversible way.

  0x00007ffff6f93fa3 <+3>:     mov    %rbp,%rax
  0x00007ffff6f93fa6 <+6>:     xor    %fs:0x30,%rax
  0x00007ffff6f93faf <+15>:    rol    $0x11,%rax
  0x00007ffff6f93fb3 <+19>:    mov    %rax,0x8(%rdi)
