b071ce2147 redo the SCM tagging strategy
Currently failing some guardian tests.

* libguile/tags.h: Refactor tagging so that tc3 bits for a pair live in
  the SCM value, not in the heap words.  Do the same for structs.  This
  more rational tagging strategy will make native code generation
  easier.  Note that this means that to check a heap pointer for its
  type, you first have to ensure that it has the expected tc3, as not
  all the type bits are on the heap.
  (SCM_TYP3): Check the SCM tag type, not the bits in the cell.
  (SCM_HAS_TYP3): New helper.
  (SCM_I_CONSP): Redefine to just check the typ3.
  (scm_tcs_cons_imcar, scm_tcs_cons_nimcar, scm_tcs_struct): Remove, as
  they are no longer necessary.

* libguile/array-handle.c (scm_i_array_implementation_for_obj): Check
  for heap objects before checking type bits, so we don't check pairs.

* libguile/evalext.c (scm_self_evaluating_p):
* libguile/gc.c (scm_i_tag_name):
* libguile/goops.c (scm_class_of)
* libguile/hash.c (scm_hasher):
* libguile/print.c (iprin1): Adapt to tagging changes.

* libguile/gc.c (scm_storage_prehistory): Register all displacements
  here.  There are the same displacements as before, unfortunately.

* libguile/list.c (SCM_I_CONS):
* libguile/pairs.c (scm_cons):
* libguile/pairs.h (scm_is_pair):
* libguile/vm-engine.h (CONS): Tag pairs with scm_tc3_pair.

* libguile/modules.c (scm_post_boot_init_modules):
* libguile/modules.h (SCM_MODULEP):
* libguile/struct.c (struct_finalizer_trampoline, scm_i_alloc_struct):
  (scm_make_vtable_vtable):
* libguile/struct.h (SCM_STRUCTP, SCM_STRUCT_VTABLE_DATA):
  (SCM_STRUCT_VTABLE_SLOTS):
* libguile/vm-i-scheme.c (make-struct): Adapt to struct tagging
  changes.

* libguile/numbers.h (SCM_I_INUMP):
* module/rnrs/arithmetic/fixnums.scm (fixnum?, inline-fixnum?): Adapt
  to the new fixnum tag.

* libguile/numbers.h (SCM_INEXACTP): Make sure of the tc3 before looking
  at the cell type.

* libguile/deprecated.c (scm_lookup_closure_module):
  (scm_module_lookup_closure):
  (scm_current_module_lookup_closure): Deprecate this part of the eval
  closure interface.  It was unused internally, after the scm_sym2var

* libguile/modules.h: Remove deprecated code.

* libguile/goops.c (scm_ensure_accessor): Use scm_module_variable
  instead of calling the lookup closure.  However I'm not sure that this
  code is used at all.

a141db8604 remove weak pairs, rewrite weak vectors
* libguile/weak-vector.c:
* libguile/weak-vector.h: Renamed from weaks.[ch].  Remove weak pairs.
  They were not safe to access with `car' and `cdr'.  Remove weak alist
  vectors, as we have weak tables and sets.  Reimplement weak vectors,
  moving the implementation here.

* libguile/vectors.c:
* libguile/vectors.h: Remove the extra header word.  Use
  scm_c_weak_vector_ref / scm_c_weak_vector_set_x to access weak
  vectors.

* libguile/snarf.h: Remove the extra header word in vectors.

* libguile/threads.c (do_thread_exit, fat_mutex_lock, fat_mutex_unlock):
  Instead of weak pairs, store thread-owned mutexes in a list of
  one-element weak vectors.

* libguile/guardians.c (finalize_guarded): Similarly, store object
  guardians in a list of one-element weak vectors.

* libguile/modules.c (scm_module_reverse_lookup): We no longer need to
  handle the case of weak references.

* libguile/print.c (iprin1): Use the standard vector accessor to print
  vectors.

* libguile.h:
* libguile/Makefile.am:
* libguile/gc-malloc.c:
* libguile/gc.c:
* libguile/goops.c:
* libguile/init.c:
* libguile/objprop.c:
* libguile/struct.c: Update includes.

* module/ice-9/weak-vector.scm: Load weak vector definitions using an
  extension instead of %init-weaks-builtins.

* test-suite/tests/weaks.test: Use the make-...-hash-table names instead
  of the old alist vector names.

* libguile/goops.c (map, filter_cpl, remove_duplicate_slots): Use
  scm_is_pair instead of !scm_is_null, given that we use accessor
  macros.
  (check_cpl, build_slots_list): Check that descendents of <class> can't
  redefine slots of <class>.

* test-suite/tests/goops.test ("defining classes"): Add a test.

ae88d9bcf6 fix CPL of <extended-generic-with-setter> and <extended-accessor>
* libguile/goops.c (fix_cpl): Fix bug in placement of debug assertion.
  (create_standard_classes): Put <extended-generic> before
  <generic-with-setter> in <extended-generic-with-setter>'s direct
  supers, so that the slot allocation is a superset of
  <generic-with-setter>, which results in the `setter' being allocated
  in the same place.

  Likewise fix <extended-accessor> to place <extended-generic> before
  <generic-with-setter>, not just <generic>.

28d0871b55 defining a smob or port type no longer mucks exports of (oop goops)
* libguile/goops.c (DEFVAR): Remove this helper macro, replacing its
  uses with scm_module_define, but without scm_module_export.
  (create_basic_classes, scm_init_goops_builtins): Update callers.
  (make_class_from_template, make_class_from_symbol): Change to not
  define variables for classes.  This affects ports, struct classes, and
  smob classes.

* module/oop/goops.scm: Explicitly list our exports, so there is no more
  trickery happening in C.
  (find-subclass): Private helper to grub the class hierarchy, so we can
  define bindings for smobs, ports, etc.  Use to define the classes that
  goops.c used to define -- probably a subset, but it's better to have
  them listed.

52fd9639fd foreign.h presents a more pointer-centric interface
* libguile/foreign.c:
* libguile/foreign.h: Rework interface to be more pointer-centric.
  Details are:
  (SCM_FOREIGN_TYPE_STRUCT, SCM_FOREIGN_TYPE_POINTER): Removed; now the
  pointer in a foreign is first-class. If it points to a native type
  like uint32, then it still has a tag; but if it points to something
  else, like a struct or a pointer or something, then its type is VOID
  (i.e., void*).
  (SCM_FOREIGN_POINTER): Rename from SCM_FOREIGN_OBJECT.
  (SCM_FOREIGN_VALUE_REF, SCM_FOREIGN_VALUE_SET): Rename from
  SCM_FOREIGN_OBJECT_REF and SCM_FOREIGN_OBJECT_SET, to indicate that
  they only work with value types.
  (SCM_FOREIGN_HAS_FINALIZER): Reserve a bit to indicate if the foreign
  pointer in question has a finalizer registered.
  (SCM_FOREIGN_LEN): For void* pointers, optionally store the length in
  bytes of the associated memory region.
  (SCM_FOREIGN_VALUE_P): Rename from SCM_FOREIGN_SIMPLE_P.
  (SCM_VALIDATE_FOREIGN_VALUE): Rename from SCM_VALIDATE_FOREIGN_SIMPLE.
  (scm_take_foreign_pointer): Rename from scm_c_take_foreign. Remove
  scm_c_from_foreign.
  (scm_foreign_type): New accessor.
  (scm_foreign_ref, scm_foreign_set_x): Take some optional args, used
  when dereferencing void pointers.

* libguile/dynl.h:
* libguile/dynl.c (scm_dynamic_pointer): New function, used by
  scm_dynamic_func. Adapt code to foreign.h changes.

* libguile/goops.c (scm_enable_primitive_generic_x)
  (scm_set_primitive_generic_x): Use the SCM_SET_SUBR_GENERIC macro.

* libguile/gsubr.c (create_gsubr): Adapt to API change.
* libguile/gsubr.h (SCM_SUBRF, SCM_SUBR_GENERIC): Store the pointer
  directly, not indirected.

* libguile/snarf.h (SCM_DEFINE, SCM_IMMUTABLE_FOREIGN): Store subr
  pointers directly. Adapt to SCM_FOREIGN_TYPE_VOID change.

* libguile/vm-i-system.c (subr-call): Access the void* directly.

cc7005bc37 remove scm_tc7_gsubr
* libguile/tags.h (scm_tc7_gsubr): Return to the pool of unused tc7s, as
  there are no more gsubrs. Yay :)

* libguile/programs.h (SCM_F_PROGRAM_IS_PRIMITIVE):
  (SCM_PROGRAM_IS_PRIMITIVE): New flag and accessor.

* libguile/gsubr.c (create_gsubr):
* libguile/snarf.h (SCM_STATIC_PROGRAM): Give subrs a PRIMITIVE flag.

* libguile/smob.h:
* libguile/smob.c (scm_i_smob_arity): New internal procedure. Uses the
  old GSUBR type macros, local to the file.

* libguile/procprop.c (scm_i_procedure_arity): Call out to
  scm_i_smob_arity, and remove a gsubr case.

* libguile/gc.c (scm_i_tag_name):
* libguile/evalext.c (scm_self_evaluating_p):
* libguile/goops.c (scm_class_of):
* libguile/vm.c (apply_foreign):
* libguile/hash.c (scm_hasher):
* libguile/debug.c (scm_procedure_name):
* libguile/print.c (iprin1): Remove gsubr cases.

* libguile/gsubr.h (SCM_PRIMITIVE_P): Fix to work with the new VM
  program regimen.
  (SCM_GSUBR_TYPE, SCM_GSUBR_MAKTYPE, SCM_GSUBR_MAX, SCM_GSUBR_REQ)
  (SCM_GSUBR_OPT, SCM_GSUBR_REST): Remove these macros, that are no
  longer useful.
* libguile/gsubr.c (scm_i_gsubr_apply, scm_i_gsubr_apply_list)
  (scm_i_gsubr_apply_array): Remove internal gsubr application
  functions.

fd12a19a5e subrs are now VM trampoline procedures
* libguile/_scm.h: Add foreign.h and programs.h to the private include
  list, as snarfing subrs with static allocation now needs access to
  some of their enums and macros.

* libguile/gsubr.c (create_gsubr): Instead of creating a tc7_gsubr
  object, create a VM program with the call-subr opcode, so that the
  representation of subrs is now gsubrs. CPP and elisp, together at
  last.
  (scm_subr_objcode_trampoline): New function, used by the SCM_DEFINE
  snarf macro.

* libguile/gsubr.h (SCM_SUBR_META_INFO, SCM_SUBR_PROPS)
  (SCM_SET_SUBR_GENERIC_LOC, SCM_SUBR_ARITY_TO_TYPE): Remove these
  macros. They were never deprecated, but hopefully people aren't using
  them.
  (SCM_SUBRF, SCM_SUBR_NAME, SCM_SUBR_GENERIC, SCM_SET_SUBR_GENERIC):
  Update to work on the new subr representation.

* libguile/objcodes.h (SCM_F_OBJCODE_IS_STATIC): New flag, indicates
  that the "backing store" of the objcode is statically allocated.

* libguile/procprop.c (scm_sym_name): Define here instead of in gsubr.c.

* libguile/snarf.h (SCM_DEFINE): If we are doing static allocation,
  statically allocate the foreign object, the object table, and the
  program, and use some SCM_SNARF_INITtery to fix things up.
  Unfortunately I have not been able to make this immutable. It might be
  possible, though.
  (SCM_IMMUTABLE_CELL, SCM_STATIC_DOUBLE_CELL, SCM_IMMUTABLE_FOREIGN):
  (SCM_STATIC_SUBR_OBJVECT, SCM_STATIC_PROGRAM): New helper macros.

6f3b0cc29e tc7 tags for vm-related data
* libguile/tags.h (scm_tc7_frame, scm_tc7_objcode, scm_tc7_vm)
  (scm_tc7_vm_cont): Take more tc7s for VM-related data structures.

* libguile/evalext.c (scm_self_evaluating_p):
* libguile/gc.c (scm_i_tag_name):
* libguile/goops.c (scm_class_of, create_standard_classes):
* libguile/print.c (iprin1): Add cases for the new tc7s.

* libguile/frames.c:
* libguile/frames.h:
* libguile/objcodes.c:
* libguile/objcodes.h:
* libguile/vm.c:
* libguile/vm.h: Desmobify.

* libguile/vm.c (scm_vm_apply): Export to Scheme, because VM objects are
  no longer applicable.

* module/system/repl/command.scm (profile):
* module/system/vm/trace.scm (vm-trace):
* module/system/vm/vm.scm (vm-load): Call vm-apply to run a program in a
  VM instead of treating the VM as applicable.

9fdf9fd3ea move subr implementation details to gsubr.[ch]
* libguile/procs.h: Move subr macros to gsubr.h.
* libguile/procs.c (scm_c_make_subr, scm_c_make_subr_with_generic)
  (scm_c_define_subr, scm_c_define_subr_with_generic): Remove these,
  because they deal in subr types, and now there is only one subr type.
  The body of this code is now in gsubr.c.

* libguile/deprecated.h (scm_subr_p): Remove from procs.[ch] and define
  as a deprecated macro. Only used internally, but who knows who's out
  there.

* libguile/goops.c (scm_generic_capability_p)
  (scm_enable_primitive_generic_x, scm_set_primitive_generic_x)
  (scm_primitive_generic_generic): Use the new SCM_PRIMITIVE_GENERIC_P
  macro instead of calling scm_subr_p.

* libguile/gsubr.h (SCM_PRIMITIVE_P, SCM_PRIMITIVE_GENERIC_P): New
  macros, to replace scm_subr_p and hacky checking for generic
  capability.
  (SCM_SUBR_META_INFO, SCM_SUBR_NAME, SCM_SUBRF, SCM_SUBR_PROPS)
  (SCM_SUBR_GENERIC, SCM_SET_SUBR_GENERIC, SCM_SET_SUBR_GENERIC_LOC)
  (SCM_SUBR_ARITY_TO_TYPE): Moved here from procs.h.

* libguile/gsubr.c (create_gsubr): Inline the
  scm_c_make_subr definition here, and work for generics too. Removed a
  scm_remember_upto_here_1 that was added earlier in the year when
  meta_info was not being traced by the GC. Adapt callers.

e2c2a6994d add foreign value wrapper
* libguile/foreign.h:
* libguile/foreign.c: New files, implementing simple wrappers around
  foreign values, such as those that one might link in dynamically from
  a library.

* libguile/tags.h (scm_tc7_foreign): Take a tc7 for foreign values.

* libguile.h:
* libguile/init.c: Add foreign.h to headers and init.

* libguile/print.c (iprin1): Add printer for foreign values.

* libguile/gc.c (scm_i_tag_name): Case for foreign values.
* libguile/goops.c (scm_class_of, create_standard_classes): Add a class
  for foreign values.

* libguile/evalext.c (scm_self_evaluating_p): Add case for foreign

d5f9864ffc remove scm_add_method
* libguile/goops.h:
* libguile/goops.c (scm_add_method): Remove this function. It didn't
  work, and even if we fixed it to work it wouldn't be as good as using
  Scheme's `add-method!'.

9ea31741da fluids are tc7 objects
If you're wondering what I'm doing, I'm trying to eventually reimplement
smobs in terms of structs, so that applicable smobs can just follow the
applicable struct dispatch path. But to do that I have to get structs
initialized before things that use smobs, which means transforming a
bunch of smobby things to tc7 things. But this transformation is good
for performance anyway, and we currently have a glut of unused tc7s,
so here we go...

* libguile/tags.h (scm_tc7_fluid, scm_tc7_dynamic_state): Fluids (and
  dynamic states) now have tc7s.

* libguile/fluids.h: Remove scm_fluids_prehistory, and add internal
  scm_i_fluid_print. Update a comment.

* libguile/fluids.c: Update for tc7 representation. Also remove the next
  pointers while we're at it, as they aren't used in the new BDW GC.

* libguile/eq.c (scm_equal_p): Remove the hashtable case. Hashtables
  could never be equal? before, I don't see why to add stubs doing the
  same thing now.

* libguile/print.c (iprin1):
* libguile/gc.c (scm_i_tag_name):
* libguile/evalext.c (scm_self_evaluating_p): Add fluid and
  dynamic_state cases.

* libguile/goops.h: Remove scm_class_hashtable; it will be static.
* libguile/goops.c: Make <hashtable> static, and add <fluid> and
  <dynamic-state> classes.

* libguile/hashtab.h:
* libguile/hashtab.c: Remove scm_i_hashtable_equal_p.

* libguile/init.c (scm_i_init_guile): Remove call to fluids_prehistory.

c99de5aa27 hash tables have a tc7
* libguile/tags.h (scm_tc7_hashtable): Allocate a tc7 for hashtables.

* libguile/hashtab.h: Adjust macros accordingly.
  (scm_i_hashtable_print, scm_i_hashtable_equal_p): New internal
  functions.
  (scm_hashtab_prehistory): Remove, no more need for this.

* libguile/hashtab.c (scm_hash_fn_remove_x): Fix a longstanding bug.
  (make_hash_table): Adapt to the new hash table representation.

* libguile/eq.c (scm_equal_p)
* libguile/evalext.c (scm_self_evaluating_p)
* libguile/print.c (iprin1)
* libguile/gc.c (scm_i_tag_name): Add some tc7_hashtab cases.

* libguile/init.c: Remove unused environments init functions. Remove
  call to hashtab_prehistory.

* libguile/goops.h (scm_class_hashtable)
* libguile/goops.c (scm_class_of, create_standard_classes): Have to
  make a class for hash tables manually, because they aren't smobs any
  more.

314b87163e eval.c closures are now applicable smobs, not tc3s
* libguile/debug.c (scm_procedure_name): Remove a SCM_CLOSUREP case and
  some dead code.
  (scm_procedure_module): Remove. This was introduced a few months ago
  for the hygienic expander, but now it is no longer needed, as the
  expander keeps track of this information itself.

* libguile/debug.h: Remove scm_procedure_module.

* libguile/eval.c: Instead of using tc3 closures, define a "boot
  closure" applicable smob type, and represent closures with that. The
  advantage is that after eval.scm is compiled, boot closures take up no
  address space (besides a smob number) in the runtime, and require no
  special cases in procedure dispatch.

* libguile/eval.h: Remove the internal functions scm_i_call_closure_0
  and scm_closure_apply, and the public function scm_closure.

* libguile/gc.c (scm_storage_prehistory): No tc3_closure displacement
  registration.
  (scm_i_tag_name): Remove closure case, and a dead cclo case.

* libguile/vm.c (apply_foreign):
* libguile/print.c (iprin1):
* libguile/procs.c (scm_procedure_p, scm_procedure_documentation);
* libguile/evalext.c (scm_self_evaluating_p):
* libguile/goops.c (scm_class_of): Remove tc3_closure/tcs_closure cases.
* libguile/hash.c (scm_hasher):

* libguile/hooks.c (scm_add_hook_x): Use new scm_i_procedure_arity.

* libguile/macros.c (macro_print): Print all macros using the same code.
  (scm_macro_transformer): Return any procedure, not just programs.

* libguile/procprop.h:
* libguile/procprop.c (scm_i_procedure_arity): Instead of returning a
  list that the caller has to parse, have the same prototype as
  scm_i_program_arity. An incompatible change, but it's an internal
  function anyway.
  (scm_procedure_properties, scm_set_procedure_properties)
  (scm_procedure_property, scm_set_procedure_property): Remove closure
  cases, and use scm_i_program_arity for arity.

* libguile/procs.h (SCM_CLOSUREP, SCM_CLOSCAR, SCM_CODE)
  (SCM_CLOSURE_NUM_REQUIRED_ARGS, SCM_CLOSURE_HAS_REST_ARGS)
  (SCM_CLOSURE_BODY, SCM_PROCPROPS, SCM_SETPROCPROPS, SCM_ENV)
  (SCM_TOP_LEVEL): Remove these macros that pertain to boot closures
  only. Only eval.c should know abut boot closures.
* libguile/procs.c (scm_closure_p): Remove this function. There is a
  simple stub in deprecated.scm now.
  (scm_thunk_p): Use scm_i_program_arity.
* libguile/tags.h (scm_tc3_closure): Remove. Yay, another tc3 to play
  with!
  (scm_tcs_closures): Remove.

* libguile/validate.h (SCM_VALIDATE_CLOSURE): Remove.

* module/ice-9/deprecated.scm (closure?): Add stub.

* module/ice-9/documentation.scm (object-documentation)
* module/ice-9/session.scm (help-doc, arity)
* module/oop/goops.scm (compute-getters-n-setters)
* module/oop/goops/describe.scm (describe)
* module/system/repl/describe.scm (display-object, display-type):
  Remove calls to closure?.

f36878ba2d remove cxrs
* libguile/pairs.h:
* libguile/pairs.c: Previously scm_cdadr et al were implemented as
  #defines that called scm_i_chase_pairs, and the Scheme-exposed
  functions themselves were cxr subrs, which got special help in the
  interpreter. Since now the special help is unnecessary (because the
  compiler inlines and expands calls to car, cdadr, etc), the complexity
  is a loss. So just implement cdadr etc using normal functions. There's
  an advantage too, in that the compiler can unroll the cxring, reducing
  branches.

* libguile/tags.h (scm_tc7_cxr): Remove this tag.
  (scm_tcs_subrs): Now there's only one kind of subr, yay!

* libguile/debug.c (scm_procedure_name)
* libguile/evalext.c (scm_self_evaluating_p)
* libguile/gc.c (scm_i_tag_name)

* libguile/procs.c (scm_procedure_p, scm_subr_p)

* libguile/vm.c (apply_foreign): Remove cxr cases. Replace uses of
  scm_tcs_subrs with scm_tc7_gsubr.

8a1f4f98e1 remove rpsubrs
* libguile/tags.h: Remove rpsubrs (I chose to interpret the terse name
  as "recursive predicate subrs"). Just use gsubrs with rest arguments,
  or do a fold yourself.

* libguile/array-map.c (scm_i_array_equal_p): Do the comparison in
  order, why not.

* libguile/chars.c:
* libguile/eq.c:
* libguile/numbers.c:
* libguile/strorder.c: Add 0,2,1 gsubr wrappers for rpsubrs like eq?, <,
  etc.

* libguile/goops.c (scm_class_of)
* libguile/procprop.c (scm_i_procedure_arity)
* libguile/procs.c (scm_thunk_p)
* libguile/vm.c (apply_foreign): Remove rpsubr cases.

* libguile/procprop.c (scm_i_procedure_arity)
* libguile/procs.c (scm_thunk_p)
* libguile/vm.c (apply_foreign): Remove cases for asubrs.

* libguile/array-map.c: Gut all of the optimizations, because there are
  no more asubrs, soon won't be rpsubrs, and all of this should happen
  on the Scheme level, ideally.

df338a2264 remove tc7_subr_* and tc7_lsubr_*
* libguile/tags.h: Remove tc7 #defines for subrs, replacing them with
  placeholders. These were public, but hopfully unused. I don't see how
  to usefully deprecate them.

* libguile/array-map.c (scm_array_map_x): Remove special cases for
  certain subr types. This might make things slower for the moment,
  otoh, native compilation should moot that question.

* libguile/eval.i.c:
* libguile/eval.c: Remove subr-handling cases. To regain this speed and
  more won't have to wait for native compilation, though -- this change
  smooths the way for subr dispatch in the VM.

* libguile/gsubr.c (scm_i_gsubr_apply): Fix a bug in which we didn't
  detect too-many-arguments. This would only show up when using ceval,
  as only ceval called this function.

* test-suite/tests/ramap.test ("array-map!"): Change the expected
  exception if passed a procedure of the wrong arity. It now gives
  wrong-num-args.
  more won't have to wait for native compilation, though -- this change
  smooths the way for subr dispatch in the VM.

* libguile/goops.c (scm_class_of): Remove subr cases. No speed
  implication.

* libguile/objects.c (scm_valid_object_procedure_p): Remove this public
  but undocumented, and useless, function. I do not think this will
  affect anyone at all.
  (scm_set_object_procedure_x): Replace a call to
  scm_valid_object_procedure_p with scm_procedure_p, and actually wrap
  with a scm_is_true.

* module/oop/goops.scm (initialize-object-procedure): Don't call
  valid-object-procedure?.

  generics, there doesn't seem to be any reason not to.

* libguile/macros.c (scm_make_synt):
* libguile/values.c (scm_init_values):
* libguile/eval.c (scm_init_eval):
* libguile/gc.c (scm_init_gc): Use scm_c_define_gsubr instead of

  generics.
