The weak table API isn't public yet. It could be after some review.
But we can go ahead and use it now internally.
* libguile/foreign.c:
* libguile/goops.c:
* libguile/objprop.c:
* libguile/procprop.c:
* libguile/smob.c:
* libguile/srcprop.c: Update weak table users to new API. No locking
needed!
* libguile/hashtab.c:
* libguile/hashtab.h: Reimplement the weak hash table implementation in
terms of weak tables. All is well except for the horrific hack for
hashx tables.
* libguile/weak-table.h:
* libguile/weak-table.c (scm_make_weak_key_hash_table)
(scm_make_weak_value_hash_table, scm_make_doubly_weak_hash_table)
(scm_weak_key_hash_table_p, scm_weak_value_hash_table_p)
(scm_doubly_weak_hash_table_p): Move these definitions here.
* libguile/weak-table.c:
* libguile/weak-table.h: New files, implementing open-addressed weak
hash tables, similar to the implementation of weak sets. This will
let us remove weak pairs.
* libguile.h:
* libguile/Makefile.am:
* libguile/evalext.c:
* libguile/gc.c:
* libguile/init.c:
* libguile/print.c:
* libguile/tags.h: Update all the pieces for the new files and tc7.
* libguile/ports.c (scm_c_make_port_with_encoding, scm_c_make_port): New
functions, to replace scm_new_port_table_entry. Use a weak set
instead of a weak table.
(scm_i_remove_port):
(scm_c_port_for_each, scm_port_for_each): Adapt to use weak set.
(scm_i_void_port): Use scm_c_make_port.
(scm_init_ports): Make a weak set.
* libguile/fports.c:
* libguile/ioext.c:
* libguile/r6rs-ports.c:
* libguile/strports.c:
* libguile/vports.c: Adapt to use the new scm_c_make_port API.
* libguile/weak-set.c:
* libguile/weak-set.h: New files, implementing weak sets, for use in the
symbol table and port set. Eventually we will be able to remove weak
pairs.
* libguile.h:
* libguile/Makefile.am: Add new files.
* libguile/evalext.c:
* libguile/gc.c:
* libguile/init.c:
* libguile/print.c:
* libguile/tags.h: Add support for the new types.
* libguile/deprecated.c (init_module_stuff,
scm_primitive_make_property): Use `scm_is_false' instead of direct
comparison to SCM_BOOL_F'.
(maybe_close_port, scm_close_all_ports_except): Use `SCM2PTR' and
`PTR2SCM' instead of wild casts.
* GUILE-VERSION (GUILE_MICRO_VERSION): Increment.
(LIBGUILE_INTERFACE_CURRENT): Increment to account for new C functions
`scm_is_exact' etc.
(LIBGUILE_INTERFACE_AGE): Increment.
* doc/ref/libguile-parallel.texi (Parallel Installations): Document the
`sitedir' and `extensiondir' pkg-config variables. This fixes
<https://savannah.gnu.org/bugs/index.php?32515>, reported by
Dale. P. Smith.
* 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.
Patch originally by Stefan Israelsson Tampe.
* module/language/tree-il/analyze.scm (analyze-lexicals): When stepping
into a non-tail form, we know that labels allocation will be invalid,
so use an empty labels set. Fixes http://debbugs.gnu.org/9769.
* test-suite/tests/tree-il.test ("labels allocation"): Add a test.
* libguile/frames.h: Instead of doing a lot of nasty pointer match and
casts here, simply define a struct that aliases the contents of a
stack frame. There are some naming issues here, that the SCM_FRAME
macros access the scm_vm_frame structure, but SCM_VM_FRAME macros
access scm_frame; oh well.
This is a followup to d32df1325d ("manual:
reorganize autoconf, pkg-config info").
* doc/ref/Makefile.am (guile_TEXINFOS): Add `libguile-parallel.texi'.
This is a followup to d32df1325d ("manual:
reorganize autoconf, pkg-config info").
* doc/ref/Makefile.am: Replace references to `autoconf.texi' by
`libguile-autoconf.texi'.
* doc/ref/scheme-using.texi (Installing Site Packages): Add a new
section about where to install .scm, .go, and .so files.
* doc/ref/tour.texi: Reference it here.
* doc/ref/guile.texi: Add new section.
* doc/ref/libguile-parallel.texi: New file, documenting parallel
installation and the use of pkg-config.
* doc/ref/libguile-linking.texi: Adapt.
* doc/ref/libguile-autoconf.texi: Rename from autoconf.texi. Lower
sections, and integrate in the "Programming in C" chapter.
* doc/ref/guile.texi: Adapt.
* module/language/tree-il/peval.scm (peval): Factor constant folding out
to a helper. Use it in the accessor case in addition to the normal
effect-free-primitive case.
* test-suite/tests/tree-il.test: Add a test.
* module/language/tree-il/peval.scm (peval): Add special handlers for
memq and memv, as inline.scm used to have. This is important for
`case' clauses. It is very ugly, though.
* test-suite/tests/tree-il.test ("partial evaluation"): Add tests.
* module/language/tree-il/primitives.scm (*primitive-accessors*): New
set of primitives: those that access mutable memory, but are otherwise
pure. Include bytevector references here.
(accessor-primitive?): New public predicate.
* module/language/tree-il/peval.scm (peval): Refactor to distinguish
constructor-primitive? from accessor-primitive?.
This commit changes to use <operand> structures to hold the context
needed to visit lexical bindings lazily, in context, instead of eagerly
visiting them for value. This laziness enables inlining of mutually
recursive bindings.
* module/language/tree-il/peval.scm (<var>): Remove comment about copy
propagation having to run build-var-table; things don't work like that
any more.
(build-var-table): Build <var> entries for all variables, even
unreferenced variables.
(alpha-rename): Remove. We will rename bindings on-demand now.
(peval lookup-var): New helper, to fetch the <var> of a gensym.
(peval fresh-gensyms): Fold here, under peval, and in it, handle
updating the store to record a mapping between new names and <var>
entries from the source program.
(peval record-source-expression): Don't call build-var-table on the
new expression, as alpha-renaming happens on-demand now.
(peval prune-bindings): Rewrite to work with mutually-recursive
bindings, while optionally preserving binding order.
(peval extend-env): New helper.
(peval loop): OK, here goes... Remove the `operand' context, as now we
visit operands lazily. Add a `call' context, which does not
copy-propagate lambda expressions, used to residualize a call after
aborting an inlining attempt. Change the `env' to be a mapping of
gensym to <operand>. Instead of looking up the operand's binding then
alpha-renaming it, just rely on the fact that visiting the operand
will rename it if necessary.
If we residualize a lexical, do so with the fresh name from the
environment. If we visit an operand and it doesn't turn out to be
constant, we will never be able to copy it, and so cache that fact in
the operand. If we residualize a binding and we know what the value
should be, record that binding so that prune-bindings won't have to
visit it again. If the operand folds to a constant, cache that too,
to save effort when unrolling loops.
For let, letrec, fix, and lambda-case, instead of visiting the
bindings eagerly for value, simply record the source expressions and
environments in an <operand> and rely on copy-propagation to visit
them later in the right context. In the case of letrec and fix, this
allows mutually-recursive bindings to be inlined.
Refactor folding of "constructors" (which still need renaming) to
avoid visiting operands twice in some contexts.
For applications, if we have to abort, process the procedure in call
context, which allows some folding but avoids copying lambdas. If we
find a recursive procedure, mark intervening counters as recursive
too, to allow for mutual recursion at the top level.
For lambdas, if we are processing for value, record the source
expression so we can detect recursion. This was previously done in
the lexical-ref copy propagator.
* test-suite/tests/tree-il.test ("partial evaluation"): Remove unused
recursive lexicals in a couple of cases. Add a couple test cases for
pruning. Add a few recursive binding cases.
* doc/ref/api-data.texi (Exact and Inexact Numbers): doc for scm_is_exact
and scm_is_inexact
* libguile/numbers.c (scm_is_exact, scm_is_inexact): new functions
* libguile/numbers.h: declarations for scm_is_exact and scm_is_inexact
* test/suite/standalone/test-conversion.c (test_is_exact, test_is_inexact):
new tests
