[release-branch.go1.21] cmd/internal/obj/arm64: fix frame pointer restore in epilogue For leaf but nonzero-frame functions. Currently we're not restoring it properly. We also need to restore it before popping the stack frame, so that the frame won't get clobbered by a signal handler in the meantime. For #63830 Fixes #65449 Needs a test, but I'm not at all sure how we would actually do that. Leaving for inspiration.
