https://gcc.gnu.org/bugzilla/show_bug.cgi?id=113077 --- Comment #4 from Alex Coplan --- So pro_and_epilogue has: ``` (insn/f 55 54 56 2 (set (mem/c:DI (plus:DI (reg/f:DI 31 sp) (const_int 16 [0x10])) [2 S8 A8]) (reg:DI 19 x19)) "t.c":2:28 -1 (expr_list:REG_CFA_OFFSE

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=113077 --- Comment #5 from Jakub Jelinek --- I think generally one shouldn't be reordering frame related instructions or needs to be extremely careful when doing so.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=113077 --- Comment #7 from Alex Coplan --- After discussing with Richard S (thanks!), I think the problem is using REG_CFA_OFFSET in aarch64_save_callee_saves is too brittle: it is always required to be expressed in terms of the current CFA reg instead

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=113077 --- Comment #8 from Alex Coplan --- Initial patch had some fallout, I was missing attaching REG_FRAME_RELATED_EXPR notes in the ldp/stp pass, testing a revised patch now...
