(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/eval.test ("define set procedure-name")["closure"]:
Change to `pass-if' since it now works, as a result of

* 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.

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.

* 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.
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
* libguile/read.c (scm_read_r6rs_block_comment):
* test-suite/tests/reader.test ("reading"): Fix reading of #||||#,
originally reported in bug debbugs.gnu.org/9672, by Bruno Haible.
Thanks, Bruno!
This was a pretty big merge involving a fair amount of porting,
especially to peval and its tests. I did not update psyntax-pp.scm,
that comes in the next commit.
