None. Since we're called from a fixed up thunk (which we want to keep
small), our only so-called argument is the EBC entry point passed in
to us in a processor register.
This is a thunk function. Microsoft x64 compiler only provide fast_call
calling convention, so the first four arguments are passed by rcx, rdx,
r8, and r9, while other arguments are passed in stack.
