* libguile/struct.h (SCM_VTABLE_INSTANCE_FINALIZER): Use DATA_REF, not
SLOT_REF.
(SCM_SET_VTABLE_INSTANCE_FINALIZER, SCM_SET_VTABLE_INSTANCE_PRINTER):
New accessor macros.
* libguile/struct.h (scm_standard_vtable_vtable)
(scm_applicable_struct_vtable_vtable)
(scm_applicable_struct_with_setter_vtable_vtable)
* libguile/struct.c: Make these stock meta-tables public to C.
* libguile/modules.c (SCM_F_EVAL_CLOSURE_INTERFACE)
(SCM_EVAL_CLOSURE_INTERFACE_P, scm_standard_interface_eval_closure):
Fix to not use SCM_CELL macros.
* libguile/smob.h: Regularize the SCM_SMOB macros, and make them all go
through some generic SMOB accessor macros.
* libguile/smob.c (scm_i_set_smob_flags): Remove, as it is unused.
* libguile/struct.h (scm_c_make_struct, scm_c_make_structv): New
functions with which you can make a struct without consing a rest
list.
* libguile/struct.c (scm_struct_init): Refactor to take an array of init
values, not a list.
(scm_make_struct, scm_make_vtable_vtable): Pull the rest arg out into
a list and pass it down to the new array-taking functions.
* libguile/memoize.c: Remove a neeless #include <alloca>.
* libguile/root.h
* libguile/root.c (scm_sys_protects): It used to be that for some reason
we'd define a special array of "protected" values. This was a little
silly, always, but with the BDW GC it's completely unnecessary. Also
many of these variables were unused, and none of them were good API.
So remove this array, and either eliminate, make static, or make
internal the various values.
* libguile/snarf.h: No need to generate calls to scm_permanent_object.
* guile-readline/readline.c (scm_init_readline): No need to call
scm_permanent_object.
* libguile/array-map.c (ramap, rafe): Remove the dubious nullvect
optimizations.
* libguile/async.c (scm_init_async): No need to init scm_asyncs, it is
no more.
* libguile/eval.c (scm_init_eval): No need to init scm_listofnull, it is
no more.
* libguile/gc.c: Make scm_protects a static var.
(scm_storage_prehistory): Change the sanity check to use the address
of protects.
(scm_init_gc_protect_object): No need to clear the scm_sys_protects,
as it is no more.
* libguile/keywords.c: Make the keyword obarray a static var.
* libguile/numbers.c: Make flo0 a static var.
* libguile/objprop.c: Make object_whash a static var.
* libguile/properties.c: Make properties_whash a static var.
* libguile/srcprop.h:
* libguile/srcprop.c: Make scm_source_whash a global with internal
linkage.
* libguile/strings.h:
* libguile/strings.c: Make scm_nullstr a global with internal linkage.
* libguile/vectors.c (scm_init_vectors): No need to init scm_nullvect,
it's unused.
* libguile/srfi-14.c (define_charset):
* libguile/deprecated.c (scm_create_hook): Don't bother making the
returned objects (hooks or charsets) into permanent objects; they are
already defined, and then the caller probably stores them away too.
* libguile/init.c (scm_i_init_guile): Add a couple annotations.
* libguile/bytevectors.c (scm_bootstrap_bytevectors): Remove a call to
scm_gc_protect_object.
* libguile/gc.h:
* libguile/gc.c (scm_init_gc_protect_object): Rename from
scm_init_storage, and just return void. Make the GC boot procs have
internal linkage.
* libguile/init.c: Adapt to the name change.
* libguile/init.c (scm_i_init_guile): Since hash tables are tc7 objects,
things that depend on hash tables no longer depend on smobs, so move
smob_prehistory up a bit. No more struct_prehistory.
* libguile/struct.h:
* libguile/struct.c (scm_struct_prehistory): Remove empty function.
* libguile/ports.h:
* libguile/ports.c (scm_ports_prehistory): Remove this function. Just
initialize global vars to NULL/0 instead of needing a prehistory
function.
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.
* 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.
* 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?.
* 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/goops.c (scm_class_of)
* libguile/hash.c (scm_hasher)
* libguile/print.c (iprin1)
* libguile/procprop.c (scm_i_procedure_arity)
* libguile/procs.c (scm_procedure_p, scm_subr_p)
(scm_make_procedure_with_setter)
* libguile/vm.c (apply_foreign): Remove cxr cases. Replace uses of
scm_tcs_subrs with scm_tc7_gsubr.
* 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.
* test-suite/tests/numbers.test ("=", "<"): Turn a couple xfails into
passes.
* libguile/tags.h (scm_tcs_subrs, scm_tc7_asubr): Remove definitions.
* 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 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.
* libguile/numbers.h:
* libguile/numbers.c (scm_i_sum): Rework so that scm_sum is just a
normal function. Its generic is actually provided by scm_i_sum, a
gsubr with rest args. In that way, + is no longer an asubr.
* libguile/tags.h: Remove scm_tc7_dsubr. There are no more users of
this.
* libguile/array-map.c:
* libguile/eval.c:
* libguile/eval.i.c:
* libguile/goops.c:
* libguile/procprop.c:
* libguile/procs.h: Remove all dsubr cases.
* libguile/deprecated.h:
* libguile/deprecated.c (scm_asinh, scm_acosh, scm_atanh): Deprecate
these stand-ins for the C99 asinh, acosh, and atanh functions. Guile
is not gnulib.
(scm_sys_atan2): Deprecate as well, in favor of scm_atan.
* libguile/numbers.h:
* libguile/numbers.c (scm_sin, scm_cos, scm_tan)
(scm_sinh, scm_cosh, scm_tanh)
(scm_asin, scm_acos, scm_atan)
(scm_sys_asinh, scm_sys_acosh, scm_sys_atanh): New functions,
replacing the combination of dsubrs and boot-9 wrappers with C subrs
that handle complex values. The latter three have _sys_ in their names
due to the name conflict with the deprecated scm_asinh et al.
Remove the $abs, $sin etc "dsubrs".
* module/ice-9/boot-9.scm: Remove transcendental functions, as this all
happens in C now.
* module/ice-9/deprecated.scm: Add aliases for $sin et al.
* test-suite/tests/ramap.test ("array-map!"): Adjust "dsubr" tests to
use sqrt, not $sqrt. They don't actually test dsubrs now. In the
two-source test, I'm pretty sure the dsubr array-map! should have been
failing, as indeed it does now; I've changed the test case to expect
the failure. I'd still like to know why it was succeeding before.
* libguile/numbers.h:
* libguile/numbers.c (scm_expt): Rename from scm_sys_expt, and handle
the complex cases as well.
* libguile/deprecated.h:
* libguile/deprecated.c (scm_sys_expt): Add a deprecated shim.
* module/ice-9/boot-9.scm (expt): Remove definition, scm_expt does all
we need.
* 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?.
* libguile/gsubr.c (create_gsubr, create_gsubr_with_generic): Always
create gsubrs -- never the specialized tc7 types. Allow gsubrs to have
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
scm_c_define_subr.
* libguile/goops.c (scm_class_of): Allow gsubrs to be primitive
generics.
* libguile/stacks.h: Rework so that a stack doesn't copy information out
of VM frames, it just holds onto a VM frame, along with the stack id
and length. VM frames are now the only representation of frames in
Guile.
(scm_t_info_frame, SCM_FRAME_N_SLOTS, SCM_FRAME_REF, SCM_FRAME_NUMBER)
(SCM_FRAME_FLAGS, SCM_FRAME_SOURCE, SCM_FRAME_PROC, SCM_FRAME_ARGS)
(SCM_FRAME_PREV, SCM_FRAME_NEXT)
(SCM_FRAMEF_VOID, SCM_FRAMEF_REAL, SCM_FRAMEF_PROC)
(SCM_FRAMEF_EVAL_ARGS, SCM_FRAMEF_OVERFLOW)
(SCM_FRAME_VOID_P, SCM_FRAME_REAL_P, SCM_FRAME_PROC_P)
(SCM_FRAME_EVAL_ARGS_P, SCM_FRAME_OVERFLOW_P): Remove these macros
corresponding to the old frame implementation.
(scm_frame_p scm_frame_source, scm_frame_procedure)
(scm_frame_arguments): These definitions are now in frames.h.
(scm_last_stack_frame): Remove declaration of previously-removed
constructor. Probably should re-instate it though.
(scm_frame_number, scm_frame_previous, scm_frame_next)
(scm_frame_real_p, scm_frame_procedure_p, scm_frame_evaluating_args_p)
(scm_frame_overflow_p) : Remove these procedures corresponding to the
old stack implementation.
* libguile/stacks.c: Update for new frames implementation.
* libguile/frames.h:
* libguile/frames.c: Rename functions operating on VM frames to have a
scm_frame prefix, not scm_vm_frame -- because they really are the only
frames we have. Rename corresponding Scheme functions too, from
vm-frame-foo to frame-foo.
* libguile/deprecated.h: Remove scm_stack and scm_info_frame data types.
* libguile/vm.c (vm_dispatch_hook): Adapt to scm_c_make_frame name
change.
* module/system/vm/frame.scm: No need to export functions provided
frames.c now, as we load those procedures into the default environment
now. Rename functions, and remove a couple of outdated, unused
functions. The bottom half of this file is still bitrotten, though.
* libguile/backtrace.c: Rework to operate on the new frame
representation. Also fix a bug displaying file names for compiled
procedures.
* libguile/init.c: Load the VM much earlier, just because we can. Also
it allows us to have frames.[ch] loaded in time for stacks to be
initialized, so that scm_frame_arguments can do the right thing.
* libguile/debug.h (scm_t_debug_frame): Remove this type, as it was
internal to the old evaluator.
(SCM_EVALFRAME, SCM_APPLYFRAME, SCM_VOIDFRAME, SCM_MACROEXPF)
(SCM_TAILREC, SCM_TRACED_FRAME, SCM_ARGS_READY, SCM_DOVERFLOW)

(SCM_SET_ARGSREADY, SCM_SET_OVERFLOW)
(SCM_CLEAR_MACROEXP, SCM_CLEAR_TRACED_FRAME, SCM_CLEAR_ARGSREADY):
Remove macro accessors to scm_t_debug_frame.
(SCM_DEBUGOBJP, SCM_DEBUGOBJ_FRAME, SCM_SET_DEBUGOBJ_FRAME):
(scm_debug_object_p, scm_make_debugobj): Remove debugobj accessors.
(scm_i_unmemoize_expr): Remove unused declaration.
* libguile/debug.c (scm_debug_options): No more max limit on frame
sizes.
(scm_start_stack): Just call out to scm_vm_call_with_new_stack.
(scm_debug_object_p, scm_make_debugobj, scm_init_debug): No more
debugobj smob type.
* libguile/deprecated.h:
* libguile/deprecated.c (scm_i_deprecated_last_debug_frame)
(scm_last_debug_frame): Remove deprecated debug-frame bits.
* libguile/stacks.c (scm_make_stack): Rework this function and its
dependents to only walk VM frames.
(scm_stack_id): Call out to the holder of the VM frame in question,
which should be a VM or a VM continuation, for the stack ID. Currently
this bit is stubbed out.
(scm_last_stack_frame): Removed. It seems this is mainly useful for a
debugger, and we need to rewrite the debugger to work on the Scheme
level.
* test-suite/tests/continuations.test ("continuations"): Remove test for
last-stack-frame.
* libguile/continuations.h (struct scm_t_contregs):
* libguile/continuations.c (scm_make_continuation):
(copy_stack_and_call, scm_i_with_continuation_barrier): No need to
save and restore debug frames.
* libguile/threads.h (scm_i_thread): Don't track debug frames.
(scm_i_last_debug_frame, scm_i_set_last_debug_frame): Remove macro
accessors.
* libguile/threads.c (guilify_self_1): Don't track debug frames.
* libguile/throw.c: No need to track debug frames in a jmpbuf.
* libguile/vm-engine.c (vm_engine, VM_PUSH_DEBUG_FRAMES): Don't push
debug frames.
* libguile/vm.h:
* libguile/vm.c (scm_vm_call_with_new_stack): New function. Currently
stubbed out though.
* libguile/eval.c (scm_primitive_eval, scm_c_primitive_eval):
(scm_init_eval): Rework so that scm_primitive_eval always calls out to
the primitive-eval variable. The previous definition is the default
value, which is probably overridden by scm_init_eval_in_scheme.
* libguile/init.c (scm_i_init_guile): Move ports and load-path up, so we
can debug when initing eval. Call scm_init_eval_in_scheme. Awesome.
* libguile/load.h:
* libguile/load.c (scm_init_eval_in_scheme): New procedure, loads up
ice-9/eval.scm to replace the primitive-eval definition, if everything
is there and up-to-date.
* libguile/modules.c (scm_module_transformer): Export to Scheme, so it's
there for eval.go.
* module/ice-9/boot-9.scm: No need to define module-transformer.
* module/ice-9/eval.scm (capture-env): Only reference the-root-module if
modules are booted.
(primitive-eval): Inline a definition for identity. Throw a more
standard error for "wrong number of arguments".
* module/ice-9/psyntax.scm (chi-install-global): The macro binding for a
syncase macro is now a pair: the transformer, and the module that was
current when the transformer was installed. The latter is used for
hygiene purposes, replacing the use of procedure-module, which didn't
work with the interpreter's shared-code closures.
(chi-macro): Adapt for the binding being a pair, and get the hygiene
from the cdr.
(eval-local-transformer): Adapt to new form of macro bindings.
* module/ice-9/psyntax-pp.scm: Regenerated.
* .gitignore: Ignore eval.go.stamp.
* module/Makefile.am: Reorder for fastest serial compilation, now that
there are no ordering constraints. I did a number of experiments here
and this seems to be the best; but the bulk of the time is compiling
psyntax-pp.scm with eval.scm. Not so great.
* libguile/vm-engine.c (vm-engine): Throw a more standard error for
"wrong type to apply".
* test-suite/tests/gc.test ("gc"): Remove a hack that shouldn't affect
the new evaluator, and throw in another (gc) for good measure.
* test-suite/tests/goops.test ("defining classes"):
* test-suite/tests/hooks.test (proc1): We can't currently check what the
arity is of a closure made by eval.scm -- or more accurately all
closures have 0 required args and no rest args. So punt for now.
* test-suite/tests/syntax.test ("letrec"): The scheme evaluator can't
check that a variable is unbound, currently; perhaps the full "fixing
letrec" expansion could fix this. But barring that, punt.
* libguile/eval.c (eval): Call scm_vm_apply instead of apply.
(apply): Deleted, no longer referenced. Heh.
(scm_apply): Call scm_vm_apply.
* libguile/init.c (scm_i_init_guile): Bootstrap the VM before the
evaluator.
* libguile/vm.c (scm_vm_apply): Actually it's not necessary that the
procedure is a program; so that's cool, relax the check.
* libguile/eval.h:
* libguile/eval.c (scm_closure_apply): New function, applies a closure.
Won't be necessary in the future, but for now here it is, with
internal linkage.
* libguile/gsubr.h:
* libguile/gsubr.c (scm_i_gsubr_apply_array): New function, applies a
gsubr to an array of values, potentially extending that array for
optional arguments and rest arguments and such.
* libguile/vm.c (apply_foreign): New function, applies a foreign
function to arguments on the stack, in place.
* libguile/vm-i-system.c (call): Add a case for procedures-with-setters
(will go away when they are applicable structs). Instead of calling
the evaluator for foreign functions, call apply_foreign.
