(make_dummy_parent): * window.c (compute_window_mirror_usage): * window.c (compute_window_usage): Overall point of this change and previous ones in this repository: (1) Introduce new, clearer terminology: everything other than int or char is a "record" object, which comes in two types: "normal objects" and "frob-block objects". Fix up all places that referred to frob-block objects as "simple", "basic", etc. (2) Provide an advertised interface for doing operations on Lisp objects, including creating new types, that is clean and consistent in its naming, uses the above-referenced terms and avoids referencing "lrecords", "old lcrecords", etc., which should hide under the surface. (3) Make the size_in_bytes and finalizer methods take a Lisp_Object rather than a void * for consistency with other methods. (4) Separate finalizer method into finalizer and disksaver, so that normal finalize methods don't have to worry about disksaving. Other specifics: (1) Renaming: LISP_OBJECT_HEADER -> NORMAL_LISP_OBJECT_HEADER ALLOC_LISP_OBJECT -> ALLOC_NORMAL_LISP_OBJECT implementation->basic_p -> implementation->frob_block_p ALLOCATE_FIXED_TYPE_AND_SET_IMPL -> ALLOC_FROB_BLOCK_LISP_OBJECT *FCCONFIG*, wrap_fcconfig -> *FC_CONFIG*, wrap_fc_config *FCPATTERN*, wrap_fcpattern -> *FC_PATTERN*, wrap_fc_pattern (the last two changes make the naming of these macros consistent with the naming of all other macros, since the objects are named fc-config and fc-pattern with a hyphen) (2) Lots of documentation fixes in lrecord.h. (3) Eliminate macros for copying, freeing, zeroing objects, getting their storage size. Instead, new functions: zero_sized_lisp_object() zero_nonsized_lisp_object() lisp_object_storage_size() free_normal_lisp_object() (copy_lisp_object() already exists) LISP_OBJECT_FROB_BLOCK_P() (actually a macro) Eliminated: free_lrecord() zero_lrecord() copy_lrecord() copy_sized_lrecord() old_copy_lcrecord() old_copy_sized_lcrecord() old_zero_lcrecord() old_zero_sized_lcrecord() LISP_OBJECT_STORAGE_SIZE() COPY_SIZED_LISP_OBJECT() COPY_SIZED_LCRECORD() COPY_LISP_OBJECT() ZERO_LISP_OBJECT() FREE_LISP_OBJECT() (4) Catch the remaining places where lrecord stuff was used directly and use the advertised interface, e.g. alloc_sized_lrecord() -> ALLOC_SIZED_LISP_OBJECT(). (5) Make certain statically-declared pseudo-objects (buffer_local_flags, console_local_flags) have their lheader initialized correctly, so things like copy_lisp_object() can work on them. Make extent_auxiliary_defaults a proper heap object Vextent_auxiliary_defaults, and make extent auxiliaries dumpable so that this object can be dumped. allocate_extent_auxiliary() now just creates the object, and attach_extent_auxiliary() creates an extent auxiliary and attaches to an extent, like the old allocate_extent_auxiliary(). (6) Create EXTENT_AUXILIARY_SLOTS macro, similar to the foo-slots.h files but in a macro instead of a file. The purpose is to avoid duplication when iterating over all the slots in an extent auxiliary. Use it. (7) In lstream.c, don't zero out object after allocation because allocation routines take care of this. (8) In marker.c, fix a mistake in computing marker overhead. (9) In print.c, clean up printing_unreadable_lcrecord(), external_object_printer() to avoid lots of ifdef NEW_GC's. (10) Separate toolbar-button allocation into a separate allocate_toolbar_button() function for use in the example code in lrecord.h.
