* config/rs6000/rs6000.h (RS6000_VARARGS_AREA, RS6000_VARARGS_SIZE):
Remove.
(STARTING_FRAME_OFFSET): Don't add RS6000_VARARGS_AREA.
(machine_function): Move typedef to...
* config/rs6000/rs6000.c (machine_function): ... here. Add
varargs_save_offset field.
(rs6000_stack_t): Remove varargs_size field.
(setup_incoming_varargs): Allocate varargs save area using
assign_stack_local, try to make it as small as possible.
Save offset from virtual_stack_vars_rtx to the save area
in cfun->machine->varargs_save_offset. Use UNITS_PER_FP_WORD
instead of magic 8 when fp word byte size is used.
(rs6000_va_start): Use cfun->machine->varargs_save_offset
instead of -RS6000_VARARGS_SIZE.
(rs6000_stack_info, debug_stack_info,
rs6000_initial_elimination_offset): Remove all traces of
varargs_size.
* config/rs6000/sysv4.h (RS6000_VARARGS_AREA): Remove.
* config/rs6000/darwin.h (STARTING_FRAME_OFFSET): Don't add
RS6000_VARARGS_AREA.
