--- Comment #7 from Jeffrey A. Law <law at gcc dot gnu.org> ---
Given the problems we've generally had in this space, it's probably quite
reasonable to treat modifications to the stack pointer as memory accesses.
It probably would have been enough to avoid the RISC-V bug I just fixed a week
or so ago.
