++ptrace
++------
++When ptracing system calls (PTRACE_SYSCALL), the pt_regs.trap value contains
++the system call type that can be used to distinguish between sc and scv 0
++system calls, and the different register conventions can be accounted for.
++
++If the value of (pt_regs.trap & 0xfff0) is 0xc00 then the system call was
++performed with the sc instruction, if it is 0x3000 then the system call was
++performed with the scv 0 instruction.
