* module/system/vm/program.scm (program-bindings-as-lambda-list): Handle
the bindings-is-null case too -- not sure how it comes about, though. A
thunk with no let, perhaps.
(write-program): Another default for the name: the source location at
which it was defined.
* libguile/programs.c (program_print): Add some "logic" to stop doing
detailed prints if one print had a nonlocal exit -- preventing
exceptions in backtraces.
* module/system/vm/frame.scm (frame-call-representation)
(frame-program-name): Rename program-name to frame-program-name, and
use the program-name if it is available.
* module/system/vm/program.scm (program-bindings): Return #f if there are
no bindings.
(program-name): New public procedure.
(program-bindings-as-lambda-list, write-program): A more useful writer
for programs.
* libguile/programs.c (scm_bootstrap_programs, program_print): Add a smob
printer for programs, which dispatches to `write-program'.
* module/language/scheme/translate.scm (primitive-syntax-table): In forms
like (define x y) where y is a lambda, and the lambda has no name yet,
set the lambda's name in its metadata.
* module/system/il/compile.scm (codegen): Fix *another* bug in compiling
`or' -- in the case in which the value was being discarded, as in `or'
used as a control structure, we were sometimes leaving a value on the
stack.
* testsuite/t-or.scm: Add another test case for `or'.
* test-suite/tests/gc.test (Unused modules are removed): Use guardians
instead of `gc-live-object-stats'. Explain failure (FIXME).
* ice-9/boot-9.scm (make-module): Add `FIXME' about circular reference.
git-archimport-id: lcourtes@laas.fr--2006-libre/guile-core--boehm-gc--0--patch-9
* libguile/threads.c (on_thread_exit): Add caveat about possible
segfault.
git-archimport-id: lcourtes@laas.fr--2006-libre/guile-core--boehm-gc--0--patch-8
* libguile/gc-malloc.c (scm_gc_malloc): Pass a non-zero size to
`GC_MALLOC ()' when SIZE is zero.

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

(scm_gc_disable): New declaration.
(scm_gc_for_alloc): Removed.
(scm_gc_for_newcell): Removed.
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

`SCM_HASHTABLE_DECREMENT ()' when a weak pair is encountered in the
source bucket.
git-archimport-id: lcourtes@laas.fr--2005-libre/guile-core--boehm-gc--1.9--patch-43
* test-suite/tests/guardians.test: Use strings instead of symbols for
`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.
(START_WEAK_BUCKET_FIXUP): Added the HASHFN argument. Invoke
`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.

(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
