I found a bug in my current patch (v5). When 32-bit tracer skips a system call, we should not update syscallno from x8 since syscallno is re-written directly via ptrace(PTRACE_SET_SYSCALL).
Ah, yes. Will aarch64 have a PTRACE_SET_SYSCALL option, or is this strictly a 32-bit vs 64-bit issue?
As discussed in a few weeks ago, aarch64 won't support PTRACE_SET_SYSCALL.
Well, I don't think anything was set in stone. If you have a compelling reason why adding the new request gives you something over setting w8 directly, then we can extend ptrace.
