// VOID
// SwitchStackThenTerminate (
//     IN PVOID StackLimit,
//     IN PVOID NewStack,
//     IN DWORD ExitCode
//     )

// Routine Description:

//     This API is called during thread termination to delete a thread's
//     stack, switch to a stack in the thread's TEB, and then terminate.

// Arguments:

//     StackLimit (a0) - Supplies the address of the stack to be freed.

//     NewStack (a1) - Supplies an address within the terminating thread's TE
//         that is to be used as its temporary stack while exiting.

//     ExitCode (a2) - Supplies the termination status that the thread
//         is to exit with.

// Return Value:

//     None.



        LEAF_ENTRY(SwitchStackThenTerminate)


// Switch stacks and then jump to FreeStackAndTerminate.


        mov     a1, sp                  // set new stack pointer
        mov     a2, a1                  // set exit code argument
        br      zero, FreeStackAndTerminate // jump
