[PATCH] D125649: [ARM SEH 7] [WIP] [ARM] Adjust the frame pointer when it's needed for SEH unwinding

[Eli Friedman via Phabricator via llvm-commits]

efriedma added a comment.

Can we just rearrange the order we save registers on the stack?  I mean, generating an extra push instruction just to satisfy the unwinder is sort of silly, but it seems like the least bad alternative.  (And we only need to do it in cases involving dynamic allocation.)

  push {r4-r5}
  push {r11, lr}
  mov r11, sp
