    Use functions and constants to manipulate Lisp_Save_Value objects. · 7b1123d8
    Paul Eggert authored
    This replaces code that used macros and strings and token-pasting.
    The change makes the C source a bit easier to follow,
    and shrinks the Emacs executable a bit.
    * alloc.c: Verify some properties of Lisp_Save_Value's representation.
    (make_save_value): Change 1st arg from string to enum.  All callers
    changed.
    (INTX): Remove.
    (mark_object): Use if, not #if, for GC_MARK_STACK.
    * lisp.h (SAVE_VALUEP, XSAVE_VALUE, XSAVE_POINTER, XSAVE_INTEGER)
    (XSAVE_OBJECT): Now functions, not macros.
    (STRING_BYTES_BOUND): Now just a macro, not a constant too;
    the constant was never used.
    (SAVE_SLOT_BITS, SAVE_VALUE_SLOTS, SAVE_TYPE_BITS, SAVE_TYPE_INT_INT)
    (SAVE_TYPE_INT_INT_INT, SAVE_TYPE_OBJ_OBJ, SAVE_TYPE_OBJ_OBJ_OBJ)
    (SAVE_TYPE_OBJ_OBJ_OBJ_OBJ, SAVE_TYPE_PTR_INT, SAVE_TYPE_PTR_OBJ)
    (SAVE_TYPE_PTR_PTR, SAVE_TYPE_PTR_PTR_OBJ, SAVE_TYPE_MEMORY):
    New constants.
    (struct Lisp_Save_Value): Replace members area, type0, type1, type2,
    type3 with a single member save_type.  All uses changed.
    (save_type, set_save_pointer, set_save_integer): New functions.
    * print.c (PRINTX): Remove.
