* libguile/gc-malloc.c (scm_gc_malloc): Pass a non-zero size to
`GC_MALLOC ()' when SIZE is zero.
git-archimport-id: lcourtes@laas.fr--2006-libre/guile-core--boehm-gc--0--patch-2

(scm_gc_stats): Rewritten. Return the (little) information available
from `libgc'.
(scm_gc_disable): New.
(scm_gc_enable): New.
(scm_storage_prehistory): Don't call `GC_add_roots ()' with
SCM_SYS_PROTECTS. Use `GC_is_visible ()' to check whether

git-archimport-id: lcourtes@laas.fr--2005-libre/guile-core--boehm-gc--1.9--patch-46
* libguile/symbols.c (lookup_interned_symbol): When a deleted weak pair
is encountered, remove it and update the hashtable's item count. Also,
check the hash table threshold and trigger a rehashing if needed.
(scm_i_c_mem2symbol): Allocate CELL using `scm_weak_car_pair ()' rather
than `scm_cons ()'.
(scm_i_mem2symbol): Likewise.
(scm_symbols_prehistory): Don't invoke `scm_permanent_object ()' for
SYMBOLS.
git-archimport-id: lcourtes@laas.fr--2005-libre/guile-core--boehm-gc--1.9--patch-44
* libguile/hashtab.c (scm_i_rehash): Don't invoke
`SCM_HASHTABLE_DECREMENT ()' when a weak pair is encountered in the
source bucket.

`g3-garbage' et al.
git-archimport-id: lcourtes@laas.fr--2005-libre/guile-core--boehm-gc--1.9--patch-42
* libguile/guardians.c (finalize_guarded): While traversing
GUARDIANS_LIST, check for deleted weak-car pairs.
(scm_i_guard): Instantiate GUARDIANS_FOR_OBJ using `scm_weak_car_pair ()'
rather than `scm_cons ()'.
git-archimport-id: lcourtes@laas.fr--2005-libre/guile-core--boehm-gc--1.9--patch-41
* libguile/hashtab.c (weak_hashtables): Removed.
(SCM_WEAK_CELL_DELETED_P): New macro.

`scm_i_rehash ()' when pairs have been removed.
(END_WEAK_BUCKET_FIXUP): Added the HASHFN argument.
(make_hash_table): Use `SCM_NEWSMOB2 ()' instead of `SCM_NEWSMOB3 ()'
-- last argument used to be WEAK_HASHTABLES.
(scm_i_rehash): Handle weak hash tables.
(to_rehash): Removed.
(scm_internal_hash_fold): Use `SCM_WEAK_CELL_DELETED_P ()' rather than
hand-written equivalent code.

* libguile/ports.c (register_finalizer_for_port): New.
(finalize_port): New.
(scm_new_port_table_entry): Call `register_finalizer_for_port ()'
before returning the new port.
(scm_ports_prehistory): Use `scm_gc_malloc_pointerless ()' instead of
`scm_gc_malloc ()' when allocating room for SCM_I_PORT_TABLE.
git-archimport-id: lcourtes@laas.fr--2005-libre/guile-core--boehm-gc--1.9--patch-37
* libguile/__scm.h (SCM_DEBUG): add SCM_DEBUG_MARKING_API
* libguile/gc.h (SCM_SET_GC_MARK): depending on
SCM_DEBUG_MARKING_API crash if someone is touching markbits
outside regular hours.
Rename ensure_marking() to scm_i_ensure_marking().
* libguile/inline.h (scm_double_cell, scm_cell): only set mark bits
for debugging if SCM_DEBUG_MARKING_API is unset
* libguile/gc-mark.c: Issue deprecation warning if we are marking
outside of the GC mark phase.
* libguile/gc-card.c: Include <config.h> and <count-one-bits.h>.
(scm_i_uint_bit_count): Remove.
(scm_i_card_marked_count): Use `count_one_bits_l ()' instead
of `scm_i_uint_bit_count ()'.
* libguile/gc-segment.c: Include <config.h> and <count-one-bits.h>.
(scm_i_heap_segment_marked_count): Use `count_one_bits_l ()' instead
of `scm_i_uint_bit_count ()'.
* libguile/private-gc.h (scm_i_uint_bit_count): Remove.
* ice-9/boot-9.scm (@, @@): Note that these don't work with the compiler.
Damn.
(top-repl): Run the VM repl. Whooo!
* module/system/repl/repl.scm (start-repl): Catch 'quit, as the
scm-style-repl does. Newline after input EOF's, so that we don't leave
the user's shell messed up.
* module/language/scheme/spec.scm (scheme): Specify an evaluator, `eval'.
* module/system/repl/common.scm (repl-default-options): Add option,
`interp', specifying that, if possible, the repl should interpret its
expressions rather than compile them. Defaults to #f.
* libguile/programs.h (struct scm_program):
* libguile/programs.c (scm_c_make_program): Record the current module
when making a program. This replaces the per-late binding recorded
module in the generated code, which should be more efficient, both in
terms of garbage, and in not calling resolve-module.
(program-module): New accessor.
* module/system/vm/program.scm: Add program-module to exports.
* libguile/vm-i-loader.c (link-later): Remove this instruction, since now
the entry in the object table is just a symbol, and can be loaded with
load-symbol.
* libguile/vm-i-system.c (late-variable-ref, late-variable-set): Rework
so as to look up in the module of the current program. The logic could
be condensed quite a bit if scm_module_lookup () knew what to do with
mod==#f.
* module/system/vm/assemble.scm (dump-object!): Dump <vlink-later> just
as load-symbol, as mentioned in the note on link-later.
* module/system/il/ghil.scm: Update comment to reflect the new reality.
* module/system/base/syntax.scm (keywords): Don't enable :keywords, it
breaks code that may assume that ':foo is a symbol, like boot-9.
* module/*.scm: Don't use :keywords, use #:keywords. The user can decide
if she wants #:keywords in their .guile, and :keywords might make us
compile modules differently.
* module/system/vm/assemble.scm (make-meta, codegen): Hide the "meta"
information -- the names of the bindings, source info, procedure
properties, etc -- behind a lambda. This way, loading up a program
conses less, because the metadata stays as mmap'd code until it is
needed.
* libguile/vm-i-loader.c (load-program): Adjust load-program to expect
the metadata to be a program.
* module/system/vm/program.scm (program-bindings, program-sources)
(program-properties): Adjust to new meta format.
* ice-9/Makefile.am (SOURCES, NOCOMP_SOURCES): Compile boot-9.scm.
Wooooo! This makes some things harder to debug, and program loading
needs to cons much less, but I think it makes sense to compile boot-9
by default if for no other reason than to catch bugs earlier.
* ice-9/boot-9.scm (defmacro:syntax-transformer, define-syntax-macro):
Removed these, as I could not see anywhere they were being used, and
they use the unnecessary procedure->syntax procedure.
* module/language/scheme/translate.scm (%forbidden-primitives): Take
procedure->memoizing-macro off probation; although it's not a good
idea, there is a fair amount of existing code that uses it that can be
compiled fine. So allow it in that case.
* ice-9/boot-9.scm: Postpone module system boot until (%app modules) is
defined, so that resolve-module will work. This might not actually be
necessary given the previous tomfoolery in resolve-module, but it
doesn't seem like a bad change.
* libguile/modules.c (module-variable): If module is #f, access the
pre-modules-array. This is so that nested-ref can work before the
module system is booted, I think.
Of course all of these dependency lines during bootstrap are just to
make sure the system can be booted properly, either interpreted or
compiled, so there's no one right way: there are many ways that could
work.
* ice-9/boot-9.scm (resolve-module): Change so that resolving '(guile)
does not require any module lookups. This is so that while within a
call to (resolve-module '(guile)), we don't recurse when looking up the
location for e.g. `append'. I can imagine other ways to get around
this, but this one seems OK.
* libguile/vm-i-system.c (late-variable-ref, late-variable-set): If the
module system isn't booted, do a simple scm_lookup. In the -ref case,
actually cache the variable location (doh!).
