* module/ice-9/boot-9.scm (macroexpand): Rename from sc-expand.
(%pre-modules-transformer): Adapt to name change.
* module/ice-9/compile-psyntax.scm: Adapt to name change.
* module/ice-9/psyntax-pp.scm: Regenerated.
* module/ice-9/psyntax.scm: Rename sc-expand to macroexpand.
* module/language/scheme/compile-tree-il.scm (compile-tree-il): Adapt to
name change.
* module/ice-9/psyntax-pp.scm: Regenerated.
* module/ice-9/psyntax.scm (chi-top-sequence): Track changes to the
current module. Allows e.g. top-level `define-module' within a begin
to work.
* test-suite/tests/syncase.test ("changes to expansion environment"):
Enable test.
* module/ice-9/psyntax.scm (build-dynlet, with-fluids): Use psyntax to
recognize `with-fluids' as a core form, producing <dynlet> if we are
compiling.
(sc-expand): To spice up the mix, use with-fluids here in the
implementation.
* module/ice-9/psyntax-pp.scm: Bootstrapped twice (!).
* module/ice-9/boot-9.scm: Remove with-fluids definition, it's in the
core now.
There are some incompatible changes here, but only to interfaces that
were introduced earlier in 1.9, or interfaces which have been broken
since early in 1.9.
* libguile/_scm.h (SCM_OBJCODE_MINOR_VERSION): Bump, as the macro
changes affect the interface that is called by psyntax-generated macro
definitions.
* libguile/inline.h (scm_words): New function, allocates a variable
number of contiguous scm_t_bits locations, with a given value in the
0th word, and 0 in the rest of the words.
* libguile/macros.h: Rework interface to correspond more closely, and
minimally, to the needs of memoize.c and psyntax.
(SCM_ASSYNT, SCM_MACRO_TYPE_BITS, SCM_MACRO_TYPE_MASK)
(SCM_F_MACRO_EXTENDED, SCM_MACROP, SCM_MACRO_TYPE)
(SCM_MACRO_IS_EXTENDED, SCM_BUILTIN_MACRO_P, SCM_SYNCASE_MACRO_P)
(SCM_MACRO_CODE, scm_tc16_macro): Remove CPP macros related to the
representation of Scheme macros.
(scm_i_make_primitive_macro): Renamed from scm_i_makbimacro.
(scm_i_macro_primitive): New accessor so that memoize.c can get to the
primitive syntax transformer.
(scm_make_syncase_macro, scm_make_extended_syncase_macro)
(scm_syncase_macro_type, scm_syncase_macro_binding): Removed these
functions, replaced by make-syntax-transformer and its accessors.
(scm_macro_binding): New accessor, the same as what
scm_syncase_macro_binding was.
* libguile/macros.c: All representation details of syntax transformers
are private to this file now.
(macro_print): Print macros as #<syntax-transformer ...>, or
#<primitive-syntax-transformer ...> if psyntax has not attached a
transformer of its own.
(scm_i_make_primitive_macro): Represent macros as 5-word smobs.
(scm_make_syntax_transformer): New constructor for syntax transformers
(macros), exported to scheme. Takes a name, and looks it up in the
current module to determine the previous primitive transformer, if
any.
(scm_macro_type): Instead of returning 'builtin-macro!, etc, return
the type as set by psyntax, or #f if it's a primitive.
(scm_macro_name): Return the stored macro name.
(scm_macro_transformer): Return the psyntax-set syntax transformer.
Hacky, but should help introspection somewhat.
* libguile/memoize.c (memoize_env_ref_transformer): Use the new
scm_i_macro_primitive, and adapt to other macro API changes.
* module/ice-9/psyntax.scm (put-global-definition-hook)
(get-global-definition-hook, chi-install-global): Call (and generate
calls to) the new macro constructors and accessors.
* module/ice-9/psyntax-pp.scm: Doubly regenerated.
* module/ice-9/debugging/traps.scm (trap-here): Comment out this
definition and export, while it's not working.
* libguile/vm-engine.c (VM_NAME): Keyword arg errors are now thrown to
'keyword-argument-error.
* libguile/vm.c: Define sym_keyword_argument_error, and statically
allocate some other symbols.
* module/ice-9/optargs.scm (parse-lambda-case): Throw to
'keyword-argument-error in kwarg error cases.
* module/ice-9/psyntax.scm (build-lambda-case): Remove a couple
workarounds for the old memoizer. Throw to 'wrong-number-of-args if
the lambda-case fails to parse.
* module/ice-9/psyntax-pp.scm: Regenerated.
* test-suite/tests/optargs.test: Update expected exceptions.
* module/ice-9/psyntax.scm (gen-label, new-mark): Labels and marks need
to be unique across read/write boundaries -- it's not sufficient for
them to simply be unique within a process by virtue of (string #\i)
constructing a new object. This used to mostly work before, because
the collapsing of duplicate constants didn't catch many syntax-object
cases -- but for some reason the attached test case brings out the
problem. So switch to use gensyms. Potentially more costly, but it's
what upstream psyntax does now.
This bug took me fully two days to figure out.
* module/ice-9/psyntax-pp.scm: Regenerated.
* test-suite/tests/syncase.test ("serializable labels and marks"): Add
test case.
I've prepared a patch that adds partial support for tail patterns.
Things like the the SRFI-34 `guard' macro from [0] are supported, but
you still can't combine dotted patterns with tail patterns, e.g.
(syntax-rules (else)
((foo bar ... (else something) . rest)
<TEMPLATE-HERE>))
will *not* work; there's the issue that one can't just transcribe
the implementation of this feature from the latest version of psyntax,
as I've done for non-dotted tail patterns, as it's implemented using a
dotted pattern like the above. Alas!
[0] <http://article.gmane.org/gmane.lisp.guile.devel/9442>
* module/ice-9/psyntax.scm (syntax-case, $sc-dispatch): Add support for
tail patterns, transcribed from the latest psyntax.
* module/ice-9/psyntax-pp.scm: Regenerated.
* test-suite/tests/syncase.test: Add tests for tail patterns.
* libguile/eval.c (scm_primitive_eval, scm_c_primitive_eval):
(scm_init_eval): Rework so that scm_primitive_eval always calls out to
the primitive-eval variable. The previous definition is the default
value, which is probably overridden by scm_init_eval_in_scheme.
* libguile/init.c (scm_i_init_guile): Move ports and load-path up, so we
can debug when initing eval. Call scm_init_eval_in_scheme. Awesome.
* libguile/load.h:
* libguile/load.c (scm_init_eval_in_scheme): New procedure, loads up
ice-9/eval.scm to replace the primitive-eval definition, if everything
is there and up-to-date.
* libguile/modules.c (scm_module_transformer): Export to Scheme, so it's
there for eval.go.
* module/ice-9/boot-9.scm: No need to define module-transformer.
* module/ice-9/eval.scm (capture-env): Only reference the-root-module if
modules are booted.
(primitive-eval): Inline a definition for identity. Throw a more
standard error for "wrong number of arguments".
* module/ice-9/psyntax.scm (chi-install-global): The macro binding for a
syncase macro is now a pair: the transformer, and the module that was
current when the transformer was installed. The latter is used for
hygiene purposes, replacing the use of procedure-module, which didn't
work with the interpreter's shared-code closures.
(chi-macro): Adapt for the binding being a pair, and get the hygiene
from the cdr.
(eval-local-transformer): Adapt to new form of macro bindings.
* module/ice-9/psyntax-pp.scm: Regenerated.
* .gitignore: Ignore eval.go.stamp.
* module/Makefile.am: Reorder for fastest serial compilation, now that
there are no ordering constraints. I did a number of experiments here
and this seems to be the best; but the bulk of the time is compiling
psyntax-pp.scm with eval.scm. Not so great.
* libguile/vm-engine.c (vm-engine): Throw a more standard error for
"wrong type to apply".
* test-suite/tests/gc.test ("gc"): Remove a hack that shouldn't affect
the new evaluator, and throw in another (gc) for good measure.
* test-suite/tests/goops.test ("defining classes"):
* test-suite/tests/hooks.test (proc1): We can't currently check what the
arity is of a closure made by eval.scm -- or more accurately all
closures have 0 required args and no rest args. So punt for now.
* test-suite/tests/syntax.test ("letrec"): The scheme evaluator can't
check that a variable is unbound, currently; perhaps the full "fixing
letrec" expansion could fix this. But barring that, punt.
Turns out this was not a very useful idea, and semantically tricky to
boot.
This reverts commit 24bf130fd1, and makes
the following additional changes:
* module/ice-9/optargs.scm (parse-lambda-case, let-optional)
(let-optional*, let-keywords, let-keywords*):
* module/language/tree-il.scm: (<lambda-case>, parse-tree-il)
(unparse-tree-il, tree-il->scheme, tree-il-fold,
make-tree-il-folder)
(post-order!, pre-order!):
* module/language/tree-il/analyze.scm (analyze-lexicals):
* module/language/tree-il/compile-glil.scm (compile-glil):
* module/language/tree-il/inline.scm (inline!): Remove all traces of
#:predicate from tree-il.
* module/ice-9/psyntax.scm (build-simple-lambda, build-lambda-case)
(chi-lambda-case): Adapt to tree-il change.
* module/ice-9/psyntax-pp.scm: Regenerated.
* module/language/brainfuck/compile-tree-il.scm (compile-body):
* module/language/ecmascript/compile-tree-il.scm (comp, comp-body):
* test-suite/tests/tree-il.test: Adapt to tree-il change.
* doc/ref/api-procedures.texi (Case-lambda): Remove mention of
#:predicate.
will be useful for making e.g. typecase-lambda. Tough to tell though.
* module/ice-9/psyntax.scm (lambda-formals, lambda*-formals): Parse out
a #:predicate, which goes right before the rest args. The vanilla
lambda doesn't parse it out of course, but it does return another
value.
(chi-lambda-case, lambda*, lambda): Expand and pass the predicate on
to build-lambda-case.
* module/ice-9/psyntax-pp.scm: Regenerate.
* module/language/tree-il/compile-glil.scm (flatten): Compile a failing
predicate without an else clause into a call to `error'. Also, fix
something the compile warnings caught.
* module/ice-9/psyntax.scm (case-lambda, case-lambda*): Add
implementations of these, present in the base environment.
* module/ice-9/psyntax-pp.scm: Regenerated.
* module/srfi/srfi-16.scm (case-lambda): Replace the core's case-lambda
definition with our own. We're not quite ready to switch yet.
* module/ice-9/psyntax.scm (lambda-formals, chi-simple-lambda)
(lambda*-formals, chi-lambda-case): Refactor the lambda
transformations with an eye to being able to do case-lambda.
* module/ice-9/psyntax-pp.scm: Regenerated.
* test-suite/tests/syntax.test: Adapted tests so that the errors we
expect match what is given by psyntax.
* module/ice-9/optargs.scm:
* module/ice-9/psyntax-pp.scm:
* module/ice-9/psyntax.scm: Make define* available in the default
environment, as lambda* is available there.
* module/ice-9/psyntax.scm (build-lambda-case): Take an "inits" arg.
Also work around a nasty memoizer bug: see
http://article.gmane.org/gmane.lisp.guile.devel/9561.
(lambda*): Implement in psyntax, in the default environment. Exciting
stuff!
* module/ice-9/psyntax-pp.scm: Regenerated.
* module/ice-9/optargs.scm (parse-lambda-case): Helper for lambda* when
we're running under the interpreter.
* module/language/tree-il.scm (<lambda-case>): Add "inits" field, so we
don't have to parse it out of opt and kw. Adapt the traversal
procedures.
* module/language/tree-il/analyze.scm (analyze-lexicals): Analyze
lexicals in the <lambda-case> init expressions as well. Fix keyword
allocation.
* module/language/tree-il/compile-glil.scm (compile-glil): Adapt to
make-lambda-case change.
(flatten): Adapt to "inits" slot, actually init uninitialized args,
and fix bugs related to keyword arguments.
* module/language/tree-il/inline.scm (inline!): Adapt a little bit --
but with no effect.
* module/language/glil/compile-assembly.scm (glil->assembly): Flesh out
<glil-kw-prelude> compilation some more. Add a "bound?" op for
<glil-lexical>, which will push #t if the local is bound.
* module/ice-9/psyntax.scm (build-simple-lambda, build-lambda-case):
Update for new signature of make-lambda-case.
* module/ice-9/psyntax-pp.scm: Regenerated.
* module/language/brainfuck/compile-tree-il.scm (compile-body):
* module/language/ecmascript/compile-tree-il.scm (comp):
* test-suite/tests/tree-il.test ("lambda"): Update for new lambda-case
syntax.
* libguile/_scm.h (SCM_OBJCODE_MINOR_VERSION): Bumparoo
* libguile/vm-i-system.c (push-rest, bind-rest): Logically there are
actually two rest binders -- one that pops, conses, and pushes, and
one that pops, conses, and local-sets. The latter is used on keyword
arguments, because the keyword arguments themselves have been shuffled
up on the stack. Renumber ops again.
* module/language/tree-il/compile-glil.scm (flatten): Attempt to handle
compilation of lambda-case with keyword arguments. Might need some
help.
* module/ice-9/psyntax.scm (build-lambda-case): An attempt to handle the
interpreted case correctly. This might need a couple iterations, but
at least it looks like the compile-glil code.
* module/ice-9/psyntax-pp.scm: Regenerated.
* module/language/glil.scm (<glil>): Rename "rest?" to "rest" in
<glil-opt-prelude> and <glil-kw-prelude>, as it is no longer a simple
boolean, but if true is an integer: the index of the local variable to
which the rest should be bound.
* module/language/glil/compile-assembly.scm (glil->assembly): Adapt to
"rest" vs "rest?". In the keyword case, use "bind-rest" instead of
"push-rest".
* test-suite/tests/tree-il.test: Update for opt-prelude change.
* module/language/tree-il.scm (<lambda>, <lambda-case>): Split lambda
into the lambda itself, denoting the procedure, and lambda-case,
denoting a particular arity case. Lambda-case is fairly featureful,
and has not yet been fully tested.
(<let-values>): Use a <lambda-case> as the binding expression. Seems
to suit the purpose well.
Adapt parsers, unparsers, traversal operators, etc. Sometimes in this
first version we assume there are no optional args, rest args, or a
predicate.
* module/language/tree-il/analyze.scm (analyze-lexicals): Adapt for the
new case-lambda regime. Fairly well commented. It actually simplifies
things.
(report-unused-variables): Update for new tree-il.
* module/language/tree-il/compile-glil.scm: Adapt for the new tree-il.
There are some first stabs here at proper case-lambda compilation, but
they are untested as of yet.
* module/language/tree-il/inline.scm (inline!): Rework so we can
recurse on a single node; though these transformations are strictly
reductive, so they should complete in bounded time. Simplify
accordingly, and adapt to case-lambda. Oh, and we handle lambda->let
in not just the nullary case.
* module/ice-9/psyntax.scm (build-simple-lambda, build-case-lambda)
(build-lambda-case): New constructors. The idea is that after syntax
expansion, we shouldn't have to deal with improper lists any more.
Build-simple-lambda is a shortcut for the common case. The others are
not fully exercised yet. Adapt callers.
(syntax): Add some debugging in the lambda case. I don't fully
understand this, but in practice we don't seem to see rest args here.
(lambda): Inline chi-lambda-clause, and adapt for build-simple-lambda.
* module/ice-9/psyntax-pp.scm: Regenerated.
* test-suite/tests/tree-il.test: Update tests for new tree-il lambda
format, and to expect post-prelude labels for all glil programs.
* module/ice-9/psyntax-pp.scm: Regenerate.
* module/ice-9/psyntax.scm (chi-top)[define-form]: If a same-named
imported variable exists, take its value instead of `#f'.
* test-suite/tests/compiler.test ("psyntax")["redefinition"]: New tests.
* module/ice-9/psyntax.scm (build-lexical-var): Make our gensyms really
unique. Before, there was a chance that different lexicals could
result in the same gensym.
* module/ice-9/psyntax-pp.scm: Regenerate.
* module/ice-9/psyntax.scm (source-wrap): Use decorate-source, for
clarity.
(syntax-type): When turning the RHS of (define (foo) ...) into a
lambda, decorate the resulting lambda expression with source
information, as the RHS later goes to chi-expr, which receives no
source information. Perhaps that is a bug. In any case, fixes some
source location lossage, reported by Jao.
* module/ice-9/psyntax-pp.scm: Regenerated.
* module/Makefile.am (ice-9/psyntax-pp.scm): Don't try autocompiling when
making psyntax-pp.scm.
* module/ice-9/psyntax-pp.scm: Regenerated.
* module/ice-9/psyntax.scm (chi-top): Only affect the compile-time
environment if modules have booted.
* libguile/vm-i-scheme.c (FUNC2): Use a signed value for the intermediate
result here. Not sure what the effect is, though.
* module/ice-9/psyntax.scm (chi-top): Toplevel definitions ensure that
variables are defined in the current module. Fixes the specific case of
guile-lib's md5.scm, which redefines + -- this code is needed so that
we don't incorrectly open-code +.
* module/language/tree-il/primitives.scm (resolve-primitives!): I think
there were some cases in which vars and names would not resolve
properly here. Fix those.
* module/ice-9/psyntax.scm (syntax-type): Remove `external-macro', not
used any more. Take an extra arg, `for-car?', indicating that we're
checking on the type of a form in the car position. In the case that
the expression is a pair, do a full recursion on the car, which allows
us to catch the fact that the car of the following form is a macro:
((@ (ice-9 optargs) let-optional) ...)
and thus the form itself should be macroexpanded.
But, since we want to distingush `lambda' from `(lambda ...)', just as
we have global and global-call, we have core to the new `core-form'.
(chi-top, chi, chi-expr, chi-body, set!): Adapt to changes to
syntax-type.
* module/ice-9/psyntax.scm (source-annotation): Return #f if
source-properties returns null.
(source-wrap): Rework a bit.
(syntax-type): Don't throw away source info for wrapped expressions.
Can has source location info, fools!
(chi-body): Correctly propagate source info for body subforms.
(syntax): Remove special case for map, it doesn't apply (ahem) for
Guile.
* module/ice-9/psyntax-pp.scm: Regenerate.
* module/ice-9/psyntax.scm: Remove references to annotation objects,
we're just going to try and use Guile's source properties now. It works
until `syntax' reconstructs output, at which point it seems we lose it.
* module/ice-9/psyntax-pp.scm: Regenerated.
* module/ice-9/psyntax.scm (chi-body): Fix a problem introduced in
dc1eed52f7, that internal syntax definitions were included in the id
lis along with value definitions. Only showed up on a second bootstrap.
Psyntax, how I love thee.
* module/ice-9/psyntax-pp.scm
* module/ice-9/boot-9.scm (cond): Implement srfi-61; most of the code is
from the SRFI itself. Yuk.
(%print-module, make-modules-in, %app, (%app modules))
(module-name): Syncase needs to get at the names of modules, even at
anonymous modules. So lazily assign gensyms as module names. Name %app
as (%app), but since (%app modules) is at the top of the module
hierarchy, name it ().
* module/ice-9/psyntax.scm: When building tree-il, try to name lambdas in
definitions and in lets.
(let, letrec): Give more specific errors in a couple of cases.
* module/ice-9/psyntax-pp.scm: Regenerated.
* test-suite/tests/syntax.test: More work. Many exceptions have different
messages than they used to, many more generic; we can roll this back to
be faithful to the original strings, but it doesn't seem necessary to
me.
* module/language/tree-il.scm (tree-il->scheme):
* module/ice-9/psyntax.scm (build-conditional): Attempt to not generate
(if #f #f) as the second arm of an if, but it doesn't seem to be
successful.
* module/ice-9/psyntax-pp.scm (syntax-rules): Regenerate.
* test-suite/tests/syntax.test (exception:unexpected-syntax): Change
capitalization.
("unquote-splicing"): Update test.
("begin"): Add in second arms on these ifs, to avoid the strange though
harmless expansion of `if'.
(matches?): New helper macro.
("lambda"): Match on lexically bound symbols, as they will be
alpha-renamed.
* module/ice-9/psyntax.scm (chi-lambda-clause): Strip the docstring
before passing it on to the continuation.
* module/ice-9/psyntax-pp.scm: Regenerated.
* test-suite/tests/eval.test (exception:failed-match): New exception, for
syntax-case failed matches.
("evaluator"): Fix macro-as-parameter tests. They pass now :)
* module/ice-9/psyntax.scm (chi-install-global, syntax-case): Fix a
couple of cases in which bare datums were passed to output
constructors.
* module/ice-9/psyntax-pp.scm: Regenerated.
* module/language/scheme/spec.scm (scheme): Clean up the #:compilers
list.
* module/language/tree-il/compile-glil.scm (flatten): Fix call to
`length' in call/cc compiler.
* libguile/vm-i-system.c:
* libguile/vm-engine.h (ASSERT_BOUND): New assertion, that a value is
bound. Used by local-ref and external-ref in paranoid mode.
* module/ice-9/boot-9.scm (and, or, cond, case, do): Since we are
switching to use psyntax as the first pass of the compiler, and perhaps
soon of the interpreter too, we need to make sure it expands out all
forms to primitive expressions. So define expanders for these derived
syntax forms, as in the R5RS report.
* module/ice-9/psyntax-pp.scm: Regenerate, with core forms fully
expanded.
* module/ice-9/psyntax.scm (build-void): New constructor, for making
undefined values.
(build-primref): Add in a hack so that primitive refs in the boot
module expand out to toplevel refs, not module refs.
(chi-void): Use build-void.
(if): Define an expander for if that calls build-conditional.
* module/language/scheme/compile-tree-il.scm (compile-tree-il): Use let*
so as not to depend on binding order for the result of
(current-module).
* module/language/scheme/spec.scm (scheme): Switch over to tree-il as the
primary intermediate language. Not yet fully tested, but at least it
can compile psyntax-pp.scm.
* module/language/tree-il/analyze.scm (analyze-lexicals): Arguments don't
count towards a function's nlocs.
* module/language/tree-il/compile-glil.scm (*comp-module*, compile-glil):
Define a "compilation module" fluid.
(flatten-lambda): Fix a call to make-glil-argument. Fix bug in
heapifying arguments.
(flatten): Fix number of arguments passed to apply instruction. Add a
special case for `(values ...)'. If inlining primitive-refs fails,
try expanding into toplevel-refs if the comp-module's variable is the
same as the root variable.
* module/language/tree-il/optimize.scm (resolve-primitives!): Add missing
src variable for <module-ref>.
* test-suite/tests/tree-il.test ("lambda"): Fix nlocs counts. Add a
closure test case.
* module/ice-9/psyntax.scm (build-lambda, build-let, build-named-let)
(build-letrec): Actually pass along the original ids to tree-il
constructors.
* module/ice-9/psyntax-pp.scm: Regenerated.
* module/language/tree-il.scm: Add fields in <lambda>, <let>, and
<letrec> for the original variable names.
* module/language/tree-il/compile-glil.scm (compile-glil): Adapt for new
make-lambda arg.
* module/ice-9/psyntax.scm (build-letrec, build-let, build-lambda)
(build-named-let): Take extra args for the original names of the
gensyms. Not used yet. Callers adapted.
* module/ice-9/psyntax-pp.scm: Regenerated.
* module/Makefile.am: Add tree-il sources.
* module/ice-9/compile-psyntax.scm: Adjust for sc-expand producing
tree-il in compile mode.
* module/ice-9/psyntax.scm: Switch from expand-support to tree-il for
generating output in compile mode. Completely generate tree-il -- the
output wasn't Scheme before, but now it's completely not Scheme.
* module/ice-9/psyntax-pp.scm: Regenerated.
* module/language/scheme/compile-ghil.scm: Strip structures using
tree-il, not expand-support.
* module/language/tree-il.scm:
* module/language/tree-il/spec.scm
* module/language/tree-il/compile-glil.scm: New language. It will compile
to GLIL, though it doesn't yet.
* module/ice-9/expand-support.scm (make-module-ref, make-lexical): Add
source arguments to these constructors.
* module/ice-9/psyntax.scm:
* module/ice-9/psyntax-pp.scm: Adapt to match, though we don't wire
everything up yet.
* module/ice-9/psyntax.scm (build-global-definition): Remove mod
argument, as it does not seem we could ever define something in another
module.
(chi-install-global): Build the define as a definition, not an
application. Doesn't matter now, but it will later.
(chi-top): Fix build-global-definition call.
* module/ice-9/psyntax.scm: Regenerated.
* module/ice-9/psyntax.scm (build-lexical-reference): Change to be a
function. Take an extra arg, the original name of the variable. If we
are compiling, make a #<lexical>, annotated with the original var name.
All callers changed.
(build-lexical-assignment): Also a function, taking also the original
var name, using build-lexical-reference to build its output.
* module/ice-9/psyntax-pp.scm: Regenerated.
* module/ice-9/psyntax.scm (*mode*): New moving part, a fluid.
(sc-expand): Dynamically bind *mode* to the expansion mode.
(build-global-reference): Change to be a procedure instead of local
syntax. Import the logic about when to make a @ or @@ form to here,
from boot-9.scm. If we are compiling, build output using (ice-9
expand-support)'s make-module-ref, otherwise just making the familiar
s-expressions. (This will allow us to correctly expand in modules in
which @ or @@ are not bound, at least when we are compiling.)
(build-global-assignment): Use the result of build-global-reference. A
bit hacky, but hey.
(top-level-eval-hook, local-eval-hook): Strip expansion structures
before evalling.
* module/ice-9/boot-9.scm (make-module-ref): Remove, this logic is now
back in psyntax.scm.
* module/ice-9/compile-psyntax.scm (source): Since we expand in compile
mode, we need to strip expansion structures.
* module/ice-9/expand-support.scm (strip-expansion-structures): Remove
the logic about whether and how to strip @/@@ from here, as it's part
of psyntax now.
* module/ice-9/psyntax-pp.scm: Regenerated.
* module/language/scheme/compile-ghil.scm (compile-ghil): Strip expansion
structures -- for now. In the future, we might translate directly from
these structures into GHIL.
* module/ice-9/boot-9.scm (sc-expand3):
* module/ice-9/psyntax.scm (sc-expand3): Replace sc-expand with
sc-expand3, as expand3 with one argument is the same as sc-expand.
* module/ice-9/psyntax-pp.scm: Regenerated.
* module/ice-9/compile-psyntax.scm:
* module/language/scheme/compile-ghil.scm: Change callers to sc-expand3
to use sc-expand.
