Turn misc objects into pseudovectors
Eliminate the category of miscellaneous objects, and turn all such objects into pseudovectors. The immediate motivation for this change is to free up an enum Lisp_Type tag value, a scarce resource that can be better used elsewhere. However, this change is worthwhile in its own right, as it improves performance slightly on my platform, 0.3% faster for 'make compile-always' on Fedora 28, and it simplifies the garbage collector and interpreter (Bug#32405). * doc/lispref/internals.texi (Garbage Collection): * etc/NEWS: Document change to garbage-collect return value. * src/alloc.c (total_markers, total_free_markers): (union aligned_Lisp_Misc, MARKER_BLOCK_SIZE) (struct marker_block, marker_block, marker_block_index) (misc_free_list, allocate_misc, live_misc_holding) (live_misc_p, sweep_misc): * src/lisp.h (lisp_h_MARKERP, lisp_h_MISCP, MARKERP, MISCP) (Lisp_Misc, enum Lisp_Misc_Type, Lisp_Misc_Free) (Lisp_Misc_Marker, Lisp_Misc_Overlay, Lisp_Misc_Finalizer) (Lisp_Misc_Ptr, Lisp_Misc_User_Ptr, Lisp_Misc_Limit) (Lisp_Misc_Bignum) (XSETMISC, struct Lisp_Misc_Any, XMISCANY, XMISCTYPE) (struct Lisp_Free, union Lisp_Misc, XMISC): Remove. All uses removed. (cleanup_vector): Clean up objects that were formerly misc and are now pseudovectors. (make_misc_ptr, build_overlay, Fmake_marker, build_marker) (make_bignum_str, make_number, make_pure_bignum) (make_user_ptr, Fmake_finalizer): Build as pseudovectors, not as misc objects. (mark_finalizer_list, queue_doomed_finalizers) (compact_undo_list, mark_overlay, mark_object) (unchain_dead_markers): Mark as vector-like objects, not as misc objects. (mark_maybe_object, mark_maybe_pointer, valid_lisp_object_p) (total_bytes_of_live_objects, survives_gc_p): * src/fns.c (sxhash): No need to worry about misc objects. (garbage_collect_1): Do not generate a 'misc' component. (syms_of_alloc): No need for 'misc' symbol. * src/buffer.c (overlays_at, overlays_in, overlay_touches_p) (overlay_strings, recenter_overlay_lists) (fix_start_end_in_overlays, fix_overlays_before) (Foverlay_lists, report_overlay_modification) (evaporate_overlays): * src/editfns.c (overlays_around): * src/data.c (Ftype_of): * src/fns.c (internal_equal): * src/lisp.h (mint_ptrp, xmint_pointer, FINALIZERP) (XFINALIZER, MARKERP, XMARKER, OVERLAYP, XOVERLAY, USER_PTRP) (XUSER_PTR, BIGNUMP, XBIGNUM): * src/print.c (print_vectorlike, print_object): * src/undo.c (record_marker_adjustments): * src/xdisp.c (load_overlay_strings): Formerly misc objects are now pseudovectors. * src/lisp.h (PVEC_MARKER, PVEC_OVERLAY, PVEC_FINALIZER) (PVEC_BIGNUM, PVEC_MISC_PTR, PVEC_USER_PTR): New constants, replacing their misc versions. All uses changed. (struct Lisp_Marker, struct Lisp_Overlay, struct Lisp_Misc_Ptr) (struct Lisp_Bignum, struct Lisp_User_Ptr, struct Lisp_Finalizer): Make usable as a pseudovector by using a pseudovector header, replacing any DIY components, and putting Lisp_Object members first. All uses changed.

574 For a Lisp_Misc, you will also need to add your entry to union
575 Lisp_Misc, but make sure the first word has the same structure as
576 the others, starting with a 16-bit member of the Lisp_Misc_Type
577 enumeration and a 1-bit GC markbit. Also make sure the overall
578 size of the union is not increased by your addition. The latter
579 requirement is to keep Lisp_Misc objects small enough, so they
580 are handled faster: since all Lisp_Misc types use the same space,
581 enlarging any of them will affect all the rest. If you really
582 need a larger object, it is best to use Lisp_Vectorlike instead.
