Bobby Bingham	b500b054c7	ppc32/64: don't store uc_link on the stack This was previously stored either in the CR (ppc64) or LR (ppc32) save area of the stack, or to one of the parameter save slots. In either case, the saved value was unused. This value is also passed to __start_context via r31, so there's no need to pass it on the stack.	2019-04-05 14:15:49 -05:00
Bobby Bingham	b9bd4045fb	ppc32/64: fix back chain pointer The ABI states that sp[0] should point to the previous stack frame, or be zero if there is no previous stack frame. makecontext previously set this slot to point to the __start_context function, rather than to a valid stack frame.	2019-04-05 14:15:49 -05:00
