/* Don't use BLKmode if VAX floats are used. */
/* Perform any needed actions needed for a function that is receiving a
variable number of arguments.
CUM is as for INIT_CUMULATIVE_ARGS.
MODE and TYPE are the mode and type of the current parameter.
PRETEND_SIZE is a variable that should be set to the amount of stack
that must be pushed by the prolog to pretend that our caller pushed
it.
Normally, this macro will push all remaining incoming registers on the
stack and set PRETEND_SIZE to the length of the registers pushed.
For VMS, we allocate space for all 6 arg registers plus a count.
However, if NO registers need to be saved, don't allocate any space.
This is not only because we won't need the space, but because AP includes
the current_pretend_args_size and we don't want to mess up any
ap-relative addresses already made. */
