Yes. As you can see, the systemstack function changes the stack
pointer back to its original value before it returns to its caller.
It does not return o
so mstart just put on stack for call traceback , but actually will not
return at mstart?

I read go runtime code，but I'm poor in assembly language,
i can't understand the following code
// switch to g0
MOVQDX, g(CX)
MOVQ(g_sched+gobuf_sp)(DX), BX
// make it look like mstart called systemstack on g0, to stop
traceback
SUBQ$8, BX
