dealing with weak vectors from C.

New Scheme interfaces to weak vectors; to be used instead of
vector-length, vector-ref, etc.
* module/ice-9/weak-vector.scm: Export the new interfaces.
* module/ice-9/boot-9.scm (define-values): Use 'generate-temporaries' to
generate a fresh name for 'dummy', to work around the lack of hygiene
for macro-introduced toplevel identifiers. Blackhole 'dummy' to avoid
keeping garbage alive. Add more comments.

before the module system is loaded. Remove redundant uses of
'compile' where 'expand' is also given. Standardize on the
"(expand load eval)" order of conditions.

'ellipsis' binding type.

Reported by taylanbayirli@gmail.com (Taylan Ulrich B.).
* module/ice-9/psyntax.scm (cvt*): Use 'syntax-case' to destructure
the pattern tail, instead of 'pair?', 'car', and 'cdr'.
(gen-clause): When checking for errors, check for misplaced ellipsis
before duplicate pattern variables, to improve the error message in
case of multiple misplaced ellipses.

Fixes <http://bugs.gnu.org/15683>.
Reported by David Pirotte <david@altosw.be>.
* module/ice-9/popen.scm: Import (ice-9 threads) and (srfi srfi-9).
(<pipe-info>): New record type.
(port/pid-table): Mark as deprecated in comment.
(port/pid-table-mutex): New variable.
(open-pipe*): Store the pid in the pipe-info record, and store the
pipe-info as a port property. Guard the pipe-info instead of the
port. Lock 'port/pid-table-mutex' while mutating 'port/pid-table'.
(fetch-pid): Removed.
(fetch-pipe-info): New procedure.
(close-process-quietly): Removed.
(close-pipe): Use 'fetch-pipe-info' instead of 'fetch-pid'. Clear
the pid from the pipe-info. Improve error messages.
(reap-pipes): Adapt to the fact that the pipe-info is now guarded
instead of the port. Incorporate the 'waitpid' code that was
previously in 'close-process-quietly', but let the port finalizer
close the port. Clear the pid from the pipe-info.
* libguile/vm.h:

scm_vm_trace_level, scm_set_vm_trace_level_x, scm_vm_engine,

Reported by Nala Ginrut <nalaginrut@gmail.com>.
* module/ice-9/psyntax.scm (include): Give a proper error message when
given a relative file name, and when the form is not in a file.
* module/ice-9/psyntax-pp.scm: Regenerate.
* module/language/tree-il/effects.scm (make-effects-analyzer): Allow
module-ref calls to be treated as bailouts, if the procedure has the
"definite-bailout?" property. Perhaps this should be renamed.
* module/ice-9/match.upstream.scm (match-error):
* module/srfi/srfi-9.scm (throw-bad-struct): Give these procedures the
definite-bailout? property.
* libguile/Makefile.am:
* libguile/vm-i-loader.c:
* libguile/vm-i-scheme.c:

build the .i files.

cases.

program cases.

* module/system/vm/program.scm: Remove old program code.
* module/ice-9/session.scm (procedure-arguments): Add an rtl-program?
case.
* module/system/vm/debug.scm (arity-arguments-alist): Use the order that
session.test expects.
* test-suite/tests/session.test ("procedure-arguments"): Adapt tests
with keywords for the new starting-with-the-procedure numbering of
locals.
* module/ice-9/eval.scm (primitive-eval): For ((lambda* (#:key foo) foo) 'bar),
give an "invalid keyword" error instead of a "wrong number of
arguments" error.
* module/ice-9/eval.scm (let-env-evaluator, primitive-eval): Evaluate
initializers of let expressions before creating the environment rib.
This prevents call/cc-related shenanigans.
* module/ice-9/match.upstream.scm (match-next): Call out to an external
procedure on error, and use a begin instead of double-parens. This
results in less generated code.
* libguile/memoize.h (SCM_M_CAPTURE_MODULE)
* libguile/memoize.c (MAKMEMO_CAPTURE_MODULE, capture_env):
(maybe_makmemo_capture_module, memoize): Determine when to capture the
module on the environment chain at compile-time, instead of at
runtime. Introduces a new memoized expression type, capture-module.
(scm_memoized_expression): Start memoizing with #f as the
environment.
(unmemoize): Add unmemoizer.
(scm_memoize_variable_access_x): Cope with #f as module, and treat as
the root module (captured before modules were booted).
* libguile/eval.c (eval):
* module/ice-9/eval.scm (primitive-eval): Adapt.
* libguile/memoize.c (MAKMEMO): Memoized objects are pairs now, not
SMOBs. This lets eval.scm destructure them more efficiently.
(scm_print_memoized, scm_memoized_p, scm_memoized_expression_typecode)
(scm_memoized_expression_data): Remove these interfaces.
(unmemoize, scm_memoize_variable_access_x): Remove SMOB type checks.
(scm_init_memoize): Remove SMOB type definition.
* libguile/memoize.h (scm_tc16_memoized, SCM_MEMOIZED_P)
(scm_memoized_expression_typecode, scm_memoized_expression_data)
(scm_memoized_p): Remove declarations.
* libguile/validate.h (SCM_VALIDATE_MEMOIZED): Remove declaration.
* libguile/eval.c (eval): Remove memoized type check, and inline the
inum unpacking.
* module/ice-9/eval.scm (memoized-expression-case): Use car and cdr to
destructure memoized expressions. A big win!
* libguile/memoize.c (MAKMEMO_LAMBDA, memoize): Instead of passing the
docstring in the memoized lambda, pass the meta as-is. That way we
get all procedure properties, including "name".
* module/ice-9/eval.scm (primitive-eval): Set procedure properties when
making lambdas. Don't set the name when defining toplevel variables
-- before we did so only if the procedure didn't have a name
property, but I would like to avoid calls to procedure-property in
eval, because getting the name for an RTL function requires loading up
other modules.
* libguile/memoize.c (MAKMEMO_LEX_REF, MAKMEMO_LEX_SET): Change to
address lexicals by depth and width.
(try_lookup_rib, lookup_rib, make_pos): New helpers.
(lookup): Adapt to return a pair.
(memoize, unmemoize_bindings, unmemoize_lexical): Adapt.
* libguile/eval.c (eval, prepare_boot_closure_env_for_eval):
(prepare_boot_closure_env_for_apply):
* module/ice-9/eval.scm (make-fixed-closure, make-general-closure)
(eval): Adapt to new environment.
This is currently a slight win for C, and a slight lose for Scheme --
because the lookup loop is so poorly compiled by the stack VM. I expect
that the RTL-compiled eval will fix this.
