* 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.
* libguile/procprop.c (scm_procedure_property)
scm_set_procedure_property_x): Fix to not call
scm_procedure_properties(), and thus to avoid consing up the arity as
well.
* libguile/vm-i-system.c (bind-rest): Renamed from push-rest-list.
(reserve-locals): Change so that instead of reserving space for some
additional number of locals, reserve-locals takes the absolute number
of locals, including the arguments.
* module/language/glil.scm (<glil-std-prelude>, <glil-opt-prelude>)
(<glil-kw-prelude>): New GLIL constructs, to replace <glil-arity>.
* module/language/glil/compile-assembly.scm (glil->assembly): Compile
the new preludes. Some instructions are not yet implemented, though.
* module/language/tree-il/analyze.scm (analyze-lexicals): The nlocs for
a lambda will now be the total number of locals, including arguments.
* module/language/tree-il/compile-glil.scm (flatten-lambda): Update to
write the new prelude.
* module/system/vm/program.scm (program-bindings-for-ip): If a given
index doesn't have a binding at the ip given, don't cons it on the
resulting list.
* test-suite/tests/tree-il.test: Update for GLIL changes.
* libguile/objcodes.h (struct scm_objcode): Remove nargs, nrest, and
nlocs, as they are no longer needed. Also obviates the need for a
padding word.
* libguile/procs.c (scm_thunk_p): Use scm_i_program_arity for programs.
* libguile/procprop.c (scm_i_procedure_arity): Use scm_i_program_arity
for programs.
(scm_procedure_properties, scm_set_procedure_properties_x)
(scm_procedure_property, scm_set_procedure_property_x): Rework so that
non-closure properties are stored directly in a weak hash, instead of
needing a weak hash of "stand-in" closures to hold the properties. Fix
docstrings also.
* libguile/root.h (scm_stand_in_procs): Remove from the scm_sys_protects
set. Actually with libGC, we should be able to store the elements of
scm_sys_protects directly as global variables.
* libguile/gc.c (scm_init_storage): Remove scm_stand_in_procs
initialization.
* libguile/programs.c (scm_i_program_arity): New private accessor, tries
to determine the "minimum arity" of a program.
* libguile/vm.c (really_make_boot_program): Adapt to changes in
struct scm_objcode.
* module/language/assembly.scm (*program-header-len*, byte-length):
* module/language/assembly/compile-bytecode.scm (write-bytecode):
* module/language/assembly/decompile-bytecode.scm (decode-load-program):
* module/language/assembly/disassemble.scm (disassemble-load-program):
Adapt to changes in objcode.
* module/system/xref.scm (program-callee-rev-vars): Adapt to changes in
assembly.
* module/language/glil.scm: Remove nargs, nrest, and nlocs from
glil-program.
* module/language/glil/compile-assembly.scm (make-meta, glil->assembly):
* module/language/glil/decompile-assembly.scm (decompile-toplevel):
(decompile-load-program): Adapt to changes in GLIL and assembly.
* module/language/tree-il/compile-glil.scm (flatten-lambda): Adapt to
changes in GLIL.
* test-suite/tests/asm-to-bytecode.test: Adapt to assembly and bytecode
changes.
* test-suite/tests/tree-il.test: Adapt to GLIL changes.
* gdbinit: Ignore SIGPWR and SIGXCPU, which the BDW GC seems to use.
* libguile/vm-engine.h (FETCH_WIDTH): Remove unused macro.
(INIT_ARGS, INIT_FRAME): Remove; callees now check their args and
reserve space for their locals.
* libguile/vm-engine.c:
* libguile/vm-i-system.c: Turn on callee arg checking and local
reservation. Seems to work!
* libguile/_scm.h (SCM_OBJCODE_MINOR_VERSION): Bump.
* libguile/vm-i-system.c (reserve-locals): New instruction, to reserve
space for local vars. Other ops renumbered.
* module/language/tree-il/compile-glil.scm (flatten-lambda): Emit
reserve-locals instructions as necessary.
* test-suite/tests/tree-il.test: Update to expect reserve-locals as
appropriate.
* libguile/objcodes.h: Bump for metadata format change.
* libguile/frames.h: Rework so we don't frob the program's nargs, nlocs,
etc at runtime. Instead we don't really know what's a local var, an
argument, or an intermediate value. It's a little unfortunate, but
this will allow for case-lambda, and eventually for good polymorphic
generic dispatch; and the nlocs etc can be heuristically
reconstructed. Such a reconstruction would be better done at the
Scheme level, though.
(SCM_FRAME_STACK_ADDRESS): New macro, the pointer to the base of the
stack elements (not counting the program).
(SCM_FRAME_UPPER_ADDRESS): Repurpose to be the address of the last
element in the bookkeeping part of the stack -- i.e. to point to the
return address.
* libguile/vm-engine.h:
* libguile/vm-i-system.c: Adapt to removal of stack_base. Though we
still detect stack-smashing underflow, we don't do so as precisely as
we did before, because now we only detect overwriting of the frame
metadata.
* libguile/vm-engine.c (vm_engine): Remove the stack_base variable. It
is unnecessary, and difficult to keep track of in the face of
case-lambda. Also fix miscommented "ra" and "mvra" pushes. Push the
vp->ip as the first ra...
* libguile/vm-i-system.c (halt): ...because here we can restore the
vp->ip instead of setting ip to 0. Allows us to introspect ips all
down the stack, including in recursive VM invocations.
* libguile/frames.h:
* libguile/frames.c (scm_vm_frame_stack): Removed, because it's getting
more difficult to tell what's an argument and what's a temporary stack
element.
(scm_vm_frame_num_locals): New accessor.
(scm_vm_frame_instruction_pointer): New accessor.
(scm_vm_frame_arguments): Defer to an implementation in Scheme.
(scm_vm_frame_num_locals scm_vm_frame_local_ref)
(scm_vm_frame_local_set_x): Since we can get not-yet-active frames on
the stack now, with our current calling convention, we have to add a
heuristic here to jump over those frames -- because frames have
pointers in them, not Scheme values.
* libguile/programs.h:
* libguile/programs.c (scm_program_arity): Remove, in favor of..
(scm_program_arities): ...this, which a list of arities, in a new
format, occupying a slot in the metadata.
* module/language/assembly/decompile-bytecode.scm (decode-load-program):
Fix mv-call decompilation.
* module/system/vm/frame.scm (vm-frame-bindings, vm-frame-binding-ref)
(vm-frame-binding-set!): New functions, to access bindings by name in
a frame.
(vm-frame-arguments): Function now implemented in Scheme. Commented
fairly extensively.
* module/system/vm/program.scm (program-bindings-by-index)
(program-bindings-for-ip): New accessors, parsing the program bindings
metadata into something more useful.
(program-arities, program-arguments): In a case-lambda world, we have
to assume that programs can have multiple arities. But it's tough to
detect this algorithmically; instead we're going to require that the
program metadata include information about the arities, and the parts
of the program that that metadata applies to.
(program-lambda-list): New accessor.
(write-program): Show multiple arities.
* module/language/glil/compile-assembly.scm (glil->assembly): Add
"arities" to the state of the compiler, and add arities entries as
appropriate.
* libguile/_scm.h (SCM_OBJCODE_MINOR_VERSION): Bump.
* libguile/vm-i-system.c (assert-nargs-ee, assert-nargs-ge)
(push-rest-list): New instructions, which for now don't actually do
anything. Renumber the rest of the ops in this file.
* module/language/glil.scm (<glil-arity>): New GLIL type, an entity that
checks the number of args for a block, optionally consing a rest list,
and either branching or erroring if the arity doesn't match.
* module/language/glil/compile-assembly.scm (glil->assembly): Compile
<glil-arity> to assembly. Some of these VM ops are not implemented --
notably the branching case.
* module/language/tree-il/compile-glil.scm (flatten-lambda): Emit
<glil-arity>.
* test-suite/tests/tree-il.test: Update.
* module/language/tree-il/analyze.scm (goops-toplevel-definition): New
procedure.
(report-possibly-unbound-variables): Check for GOOPS top-level
definitions.
* test-suite/tests/tree-il.test ("warnings")["GOOPS definitions are
visible"]: New test.
Partly fixes bug #23681 ("Function declarators with empty parentheses
should not be used").
* libguile/goops.c (scm_wrap_component): Cast `scm_sloppy_assq'.
* libguile/hashtab.c (scm_hash_fn_get_handle): Update to take functions
of type `scm_t_hash_fn' and `scm_t_assoc_fn'. Update callers.
(scm_ihashx): Change to match `scm_t_hash_fn'.
(scm_sloppy_assx): Change to match `scm_t_assoc_fn'.
* libguile/hashtab.h (scm_t_hash_fn, scm_t_assoc_fn): New types.
(scm_t_hashtable)[hash_fn]: Change to `scm_t_hash_fn'.
(scm_i_rehash, scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
scm_hash_fn_ref, scm_hash_fn_set_x, scm_hash_fn_remove_x): Change to
take `scm_t_hash_fn' and `scm_t_assoc_fn' parameters.
* libguile/srcprop.h (scm_whash_get_handle, scm_whash_create_handle,
scm_whash_lookup): Implement in terms of `scm_hashq_*' instead of
`scm_hash_fn_*'.
* libguile/struct.c (scm_struct_ihashq): Change to match
`scm_t_hash_fn'.
(scm_struct_create_handle): Cast `scm_sloppy_assq'.
* libguile/struct.h (scm_struct_ihashq): Update, make internal.
* module/ice-9/boot-9.scm (make-fresh-user-module): New public function,
makes an anonymous beautified module.
* module/language/objcode/spec.scm: We used to have some things in here
that allowed lexical variable names and values to be a part of the
environment, but no more. Now an environment is just a module. If you
want to "inject" free variables into code, just use lambda.
* module/language/scheme/compile-tree-il.scm (compile-tree-il): Same
here. Also, rely on the fact that an environment *will* be a module --
because (system base compile) guarantees that for us.
* module/language/scheme/spec.scm (scheme): In the reader, rely on the
environment being a module. Define a #:make-default-environment
handler, which returns a beautified module, augmented with a fresh
definition for current-reader, so that side effects to current-reader
are restricted to the compilation unit.
* module/language/tree-il/analyze.scm
(report-possibly-unbound-variables):
* module/language/tree-il/compile-glil.scm (compile-glil):
* module/language/tree-il/optimize.scm (optimize!): The environment will
be a module.
* module/system/base/language.scm (<language>): New field,
`make-default-environment'. Defaults to `make-fresh-user-module'.
(default-environment): New accessor, returns a default environment for
a language.
* module/system/repl/common.scm (repl-compile): Always compile relative
to the current module, because a module is always acceptable as an
environment.
* module/system/base/compile.scm (compile-file, compile-and-load): Both
of these have a new keyword argument, #:env. For `compile-file', it
defaults to the default environment of the source language, and for
`compile-and-load', to the current module.
(read-and-compile): If there are no expressions read, pass the joiner
its default environment (via `default-environment joint').
* module/system/base/compile.scm (current-compilation-environment):
Remove, as the only thing that needed it (language readers) now get
the environment as an argument.
(read-and-compile, compile): Rework for no *compilation-environment*,
and default the environment using the define* mechanism.
* module/language/tree-il/analyze.scm (env-module): Hack around the lack
of a current compilation module. Will fix this in the next commit so
that the environment is always valid.
* module/language/assembly/spec.scm:
* module/language/brainfuck/spec.scm:
* module/language/bytecode/spec.scm:
* module/language/ecmascript/spec.scm:
* module/language/glil/spec.scm:
* module/language/scheme/spec.scm:
* module/language/tree-il/spec.scm: Language-readers now take two
arguments: the port and the environment. This should allow for
compile-environment-specific reader behavior.
* module/system/base/compile.scm (read-and-compile):
* module/system/repl/common.scm (repl-read): Pass the environment to the
language-reader.
* module/system/repl/repl.scm (meta-reader, prompting-meta-read):
* module/system/repl/command.scm (define-meta-command): Use the second
argument to repl-reader, so we avoid frobbing current-reader.
* module/ice-9/boot-9.scm (repl-reader): Accept an optional second
argument, the reader to use. If it is given, use it instead of
dereferencing the current-reader fluid.
* guile-readline/ice-9/readline.scm (activate-readline): Make our
replacement definition of repl-reader compatible with boot-9.
GHIL is obsolete, and it's about time we got rid of it. Elisp and R5RS
were unmodified since their import from Guile-VM, so we ditch them too.
R5RS compilation is supported via compiling Scheme within an R5RS
environment.
Elisp will be supported when we merge in Daniel's work.
* libguile/arrays.c (scm_from_contiguous_typed_array):
* libguile/bytevectors.c (scm_uniform_array_to_bytevector): Error if the
uniform element size is more than 8 bits, but not divisible by 8 --
because our math could overflow in that case.
* module/ice-9/deprecated.scm (#\y): Indeed, #* is the valid bitvector
syntax :)
* libguile/arrays.c (scm_from_contiguous_typed_array): Fix BYTE_LEN
sanity check for bitvectors.
* test-suite/tests/unif.test ("syntax")["bitvector is self-evaluating"]:
New test.
* module/ice-9/deprecated.scm (#\y): Fix deprecation comment: `#*' is
not a read syntax.
* libguile/bytevectors.c (scm_uniform_array_to_bytevector): Fix BYTE_LEN
computation for bitvectors.
* test-suite/tests/bytevectors.test ("uniform-array->bytevector"): New
test prefix.
This is a followup to 87c595c757 ("Compile
in a fresh module by default.") and
f65e2b1ec5 ("Honor and confine
expansion-time side-effects to `current-reader'.").
* doc/ref/api-evaluation.texi (Loading): Explain how to change
`current-reader' in a compiler-friendly way.
* doc/ref/compiler.texi (The Scheme Compiler): Explain use of a fresh
compilation module and separate `current-reader' fluid.
* test-suite/tests/compiler.test ("current-reader")["with eval-when"]:
New test.
* module/ice-9/boot-9.scm (load): Pull `autocompiled-file-name' inside
`load', and make it autocompile in the current module. Should fix
Julian's issue noted in
http://article.gmane.org/gmane.lisp.guile.devel/9483.
The incompatibility was introduced by
0fb81f95b0 ("add exception_on_error
optional arg to primitive-load-path").
* libguile/load.c (scm_primitive_load_path): Change to take 1 rest
argument. Interpret the argument as either a file name (C-level
backward compatibility with 1.8) or an actual argument list.
(scm_c_primitive_load_path): Update caller.
* libguile/load.h (scm_primitive_load_path): Update accordingly.
* doc/ref/api-evaluation.texi (Loading): Update documentation of
`primitive-load-path' and `scm_primitive_load_path ()'.
* libguile/Makefile.am (libpath.h): Fix SCM_LIB_DIR to point to the
libdir, not pkglibdir. Add SCM_EXTENSIONS_DIR, for a dir to put in the
dynamic-link search path that's not managed by ldconfig or the like;
and put this dir in the "extensionsdir" key of %guile-build-info.
* libguile/dynl.c (sysdep_dynl_init): Rename the installed-libdir
environment var to GUILE_SYSTEM_EXTENSIONS_PATH (from
GUILE_SYSTEM_LTDL_PATH). Also add SCM_EXTENSIONS_DIR to the ltdl
search path in the default case.
* meta/uninstalled-env.in: Adapt override to match.
* meta/guile-2.0.pc.in: Add extensionsdir, so you can pkg-config
--variable=extensionsdir guile-2.0.
* test-suite/tests/regexp.test (set-latin-1): also add .ISO8859-1 as a
possible extension for latin-1 locales. Use set-latin-1 exclusively
to set the locale for tests.
The method used was not portable. However, the underlying problem
still exists: the uc_locale_language used by libunistring does not
work with thread-specific locale_t locales.
* libguile/i18n.c (locale_language): avoid unpacking semi-opaque type
locale_t.
* test-suite/tests/i18n.test: set Turkish string and char locale upcase
and downcase tests to throw untested
In libgc CVS the `GC_do_blocking ()' declaration is now public but it
uses a slightly different signature for its first argument.
* configure.ac: Check for `GC_fn_type'.
* libguile/threads.c (GC_fn_type)[HAVE_GC_DO_BLOCKING &&
!HAVE_GC_FN_TYPE]: New typedef.
(scm_without_guile): Explicitly cast `without_guile_trampoline' to
`GC_fn_type'. This is because the upstream definition currently
looks like `typedef void * (extern *GC_fn_type)(void *);', which
isn't compatible.
* libguile/__scm.h (scm_async_tick): New declaration.
(SCM_ASYNC_TICK)[!BUILDING_LIBGUILE]: Use `scm_async_tick ()'.
* libguile/async.c (scm_critical_section_start,
scm_critical_section_end, scm_async_tick): New functions.
* libguile/async.h (scm_i_critical_section_mutex): Made internal.
(scm_critical_section_start, scm_critical_section_end): New
declarations.
(SCM_CRITICAL_SECTION_START,
SCM_CRITICAL_SECTION_END)[!BUILDING_LIBGUILE]: Use the same-named
function (lower-case).
* libguile/stackchk.h (SCM_STACK_OVERFLOW_P): Conditionalize on
`BUILDING_LIBGUILE'.
* libguile/threads.h (SCM_I_CURRENT_THREAD, scm_i_dynwinds,
scm_i_set_dynwinds, scm_i_last_debug_frame,
scm_i_set_last_debug_frame): Conditionalize on `BUILDING_LIBGUILE'.
