/*++ @file
Since the SEC is the only program in our emulation we
must use a UEFI/PI mechanism to export APIs to other modules.
This is the role of the EFI_EMU_THUNK_PROTOCOL.
The mUnixThunkTable exists so that a change to EFI_EMU_THUNK_PROTOCOL
will cause an error in initializing the array if all the member functions
are not added. It looks like adding a element to end and not initializing
it may cause the table to be initaliized with the members at the end being
set to zero. This is bad as jumping to zero will crash.

# Routine Description:
#
# Routine for switching stacks with 2 parameters EFI ABI
# Convert UNIX to EFI ABI
#
# Arguments:
#
# (rdi) EntryPoint - Entry point with new stack.
# (rsi) Context1 - Parameter1 for entry point. (rcx)
# (rdx) Context2 - Parameter2 for entry point. (rdx)
# (rcx) NewStack - The pointer to new stack.
#
# Returns:
#
# None

movq %rsp, %rbp
movq %rcx, %rsp // update stack pointer
movq %rdi, %rax // entry point to %rax
movq %rsi, %rcx // Adjust Context1
// Context2 already in the rigth spot
#
# Reserve space for register parameters (rcx, rdx, r8 & r9) on the stack,
# in case the callee wishes to spill them.
