Good idea.
Depending on the architecture there might still need to be
restrictions on use of the stack pointer, eg aarch64's
alignment requirements, but this at least means you can
in theory write some risu rules that use SP.
I really want use alternate stack, this way can reduce risu rules.
what about use this only on LoongArch architecture ?
Thanks.
