* ginclude/stdarg.h: Include va-mn10300.h.
* ginclude/varargs.h: Likewise.
* ginclude/va-mn10300.h: New file.
* mn10300/mn10300.c (expand_prologue): If current_function_varargs is
nonzero, then flush d0/d1 back into the stack.
(mn10300_builtin_saveregs): New function.
(function_arg, function_arg_partial_nregs): New functions.
(initial_offset): Tweak now that the RP save area is allocated
and deallocated around each call again.
* mn10300/mn10300.h (FIRST_PARM_OFFSET): Now 4.
(FRAME_POINTER_REQUIRED): Require a frame pointer for all non-leaf
functions.
(REG_PARM_STACK_SPACE): Now 8 bytes.
(FUNCTION_ARG_REGNO_P): Update for new parameter passing conventions.
(CUMULATIVE_ARGS, INIT_CUMULATIVE_ARGS): Likewise.
(FUNCTION_ARG_ADVANCE, FUNCTION_ARG): Likewise.
(FUNCTION_ARG_PARTIAL_NREGS): Likewise.
(TRAMPOLINE_TEMPLATE): Don't clobber d0 anymore.
(TRAMPOLINE_SIZE, INITIALIZE_TRAMPOLINE): Corresponding changes.
(EXPAND_BUILTIN_SAVEREGS): Define.
* mn10300/mn10300.md (call, call_value patterns): Allocate and
deallocate a stack slot for the return pointer around each call.
* mn10300/mn10300.h (RTX_COSTS): Refine.
(CASE_VALUES_THRESHHOLD, NO_FUNCTION_CSE): Likewise.
* mn10300/mn10300.c (output_tst): New function.
* mn10300/mn10300.md (movdi, movdf): Improve code to load constants
into registers.
(tst insns): Use output_tst to optimize some cases. Add versions to
encourage more zero extensions instead of sign extensions of HImode
and QImode values.
(divsi3, udivsi3): Remove patterns. Replaced by...
(divmodsi4, udivmodsi4): New expanders/patterns.
(andsi3): Optimize "and" operations with certain constants.
