  xchg %rsp, %rdi
complete rewrite! featuring 7ns inlineable context switches, no more separately-built assembly objects, and a vastly nicer interface. incontext/outcontext are no more, context switch calls now take a single context structure, which functions as both. everything now also functions without any heap allocations -- for the context setup, only an FnOnce() value is necessary. 2015-01-14 15:31:17 +08:00			`xchg %rsp, %rdi`
