multiple value truncation.
* test-suite/tests/asm-to-bytecode.test (%objcode-cookie-size)
(test-target): The objcode version embedded in the cookie is not an
effective version, so elide it from the test.
* module/web/uri.scm (parse-authority): Allow empty authorities, so that
we accept URIs of the form, file:///etc/hosts.
* test-suite/tests/web-uri.test ("string->uri"): Add tests.
* module/ice-9/boot-9.scm (<parameter>, make-parameter, parameter?)

`memcpy'.
* test-suite/tests/bytevectors.test ("2.2 General
Operations")["bytevector-copy! overlapping"]: New test.
* doc/ref/api-data.texi (Bytevector Manipulation): Mention possible
overlapping.
* test-suite/tests/eval.test ("stacks"): Enable another test, fix to use
with-throw-handler, and remove a duplicate test, now that there is no
difference between subrs and gsubrs.
These tests had been disabled as part of
b7742c6b71 ("new evaluator, y'all").
* test-suite/tests/eval.test ("define set procedure-name")["closure"]:
Change to `pass-if' since it now works, as a result of
ee15aa46e3 ("set names of functions
defined at the toplevel from `eval'").
("stacks")["arguments of a gsubr stack frame"]: Remove (throw
'unresolved).
* libguile/procprop.c (scm_set_procedure_minimum_arity_x): New
function, allows a user to override a function's arity.
(scm_i_procedure_arity): Look up in the overrides table first.

closures".

Based on a patch from Stefan Israelsson Tampe. Test based on work by
Patrick Bernaud.
* libguile/bitvectors.c (scm_bit_set_star_x): Fix a long-standing (since
2005) bug in which instead of using the kv bitvector, we actually use
the `v' bitvector. Also, change to allow `kv' being shorter than
`v'.
* test-suite/tests/bitvectors.test ("bit-set*!"): Add tests.
* module/language/tree-il/compile-glil.scm (flatten-lambda-case): Clear
lexical stack slots at the end of a non-tail let, letrec, or fix.
Fixes http://debbugs.gnu.org/9900.
* test-suite/tests/gc.test ("gc"): Add test.
* module/language/tree-il.scm (<tree-il>): Add `pre' and `post' fields
to <dynwind>, so that we can inline the guard bodies in the normal
control-flow case. It also avoids duplicating code in compile-glil,
which probably hides more bugs in 2.0.
(parse-tree-il, unparse-tree-il, tree-il->scheme, tree-il-fold)
(make-tree-il-folder, post-order!, pre-order!): Update.
* module/language/tree-il/analyze.scm (analyze-lexicals): Update.
* module/language/tree-il/compile-glil.scm (flatten-lambda-case): Update
to use `pre' and `post' instead of compiling code twice.
* module/language/tree-il/debug.scm (verify-tree-il): Update.
* module/language/tree-il/peval.scm (peval): Update. Instead of doing
complicated things in <dynwind>, handle 'dynamic-wind primcalls.

Remove 'dynamic-wind mess. Adapt '@dynamic-wind.
* test-suite/tests/tree-il.test ("partial evaluation"): Update tests.
* module/language/tree-il/peval.scm (peval): The <dynwind> compiler will
copy the winder and unwinder values, so make sure that they are
constant, and if not, create lexical bindings. Fixes
http://debbugs.gnu.org/9844.
* test-suite/tests/tree-il.test ("partial evaluation"): Add a couple
<dynwind> tests.
* module/language/tree-il/peval.scm (peval): Accessor primitives applied
to constants are pure if the call type-checks. Also, fold constants
in accessor primcalls.
* test-suite/tests/tree-il.test ("partial evaluation"): Fix the "yo"
test.
* 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/gc.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.
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.
* 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.
