* module/ice-9/getopt-long.scm (option-spec-fields): Enclose in a
`(load-toplevel compile-toplevel)' `eval-case'.
(define-one-option-spec-field-accessor,
define-one-option-spec-field-modifier): Enclose in a
`compile-toplevel'-only `eval-case'.
* module/language/ecmascript/parse.scm (parse-ecmascript): And update the
function declaration forms for the new var syntax.
* module/language/ecmascript/compile-ghil.scm (comp): Support foo["bar"]
in addition to foo.bar.
* module/language/ecmascript/impl.scm (pget, pput): Some fixes for when
we get non-symbols -- it can happen, yo. I suppose we should allow for
non-string keys too..
* module/language/ecmascript/compile-ghil.scm (@impl): Ok, don't recurse
on args here.
(comp): Implement property gets and puts and lexical assignment.
(comp-body): Fix scanning of var forms.
* module/language/ecmascript/impl.scm (prop-attrs): Allow for the prop
attr array to be #f.
* module/language/ecmascript/parse.scm (parse-ecmascript): Fix assignment
parsing.
* libguile/vm-i-system.c (drop, return): Declare drop and return as
popping one arg from the stack.
* module/language/ghil/compile-glil.scm:
* module/language/glil/compile-assembly.scm (make-meta): Adjust so that
we declare 'drop and 'return calls as popping one arg from the stack.
* module/language/ecmascript/compile-ghil.scm (comp, comp-body): Flesh
out a bit more. Most significantly, scoping within functions obeys
javascript semantics better, modulo bits about with() forms.
* module/language/ecmascript/impl.scm: Define some runtime helper
routines.
* module/language/Makefile.am (SOURCES): Add impl.scm.
* module/language/ecmascript/parse.scm (parse-ecmascript): Minor tweaks.
* module/language/ecmascript/tokenize.scm (read-identifier): Identifiers
now read as symbols, not strings.
* module/language/ecmascript/parse.scm (parse-ecmascript): Lambdas always
just have one member in their bodies.
* module/language/ecmascript/compile-ghil.scm (comp): Add some more silly
compilers.
* module/language/ecmascript/parse-lalr.scm: Add the Boucher/Bison lalr
parser. This is from guile-lib, but with : changed to -> so as not to
molest `prefix' keywords. Should probably be elsewhere.
* module/language/ecmascript/parse.scm: Add parser for ECMAScript. Rules
from the spec, 3rd edition.
* module/language/ecmascript/tokenize.scm: Add ECMAScript tokenizer,
hand-written. Neat stuff.
* module/language/Makefile.am: Autofoo.
* module/language/assembly.scm (align-program): Whoops, align programs
properly.
* module/language/glil/compile-assembly.scm (compile-assembly): Start
with addr=-1, for the unserialized load-program byte.
(glil->assembly): Align programs in all cases.
* module/system/base/compile.scm (compiled-file-name): Prepend "(dirname
file)" so that "guile-tools compile foo/bar.scm" produces
"foo/bar.go", not "bar.go".
* module/language/assembly.scm (addr+): New helper.
(align-program): New function, aligns a (load-program) form, currently
to 8-byte boundaries.
* module/language/glil/compile-assembly.scm (<subprogram>): Record the
object table and the program code separately, so that we can align the
program after the object table has been written.
(glil->assembly): Use addr+.
(dump-object): Rework to fold `addr' through dumping of compound
objects, so that procedures can be aligned properly.
* module/language/scheme/compile-ghil.scm (define-scheme-translator):
Only add an else clause if the transformer didn't have one.
* module/oop/goops.scm (min-fixnum, max-fixnum): Define at compile-time
as well.
(@slot-ref, @slot-set!): Only define transformers for these at
compile-time. Avoids loading up the compiler unnecessarily. Also, allow
for the `n' to be determined lexically, in which case we dispatch to
the primitive.
(num-standard-pre-cache, define-standard-accessor-method)
(bound-check-get, standard-get, standard-set): Rework the fixed-offset
getters and setters so that they can be computed at compile-time.
Accessors to fields with n > num-standard-pre-cache will be dispatched
to the primitive instead of within the VM.
* libguile/goops.c (scm_make): In the pre-inst `make', default
`procedure' to #f, and read a `make-procedure' instead of
`compile-env'.
* libguile/goops.h (scm_si_make_procedure): This instead of
scm_si_compile_env.
* module/oop/goops.scm (make-method): Remove this unused function. Users
should use (make <method> ...) directly.
(method): Capture `make-procedure' instead of `procedure' in the case
that the body calls a next-method. Allows for the kind of
"recompilation" that we were using before, but with closures instead of
re-entering the compiler. Type-specific compilation is still
interesting, but probably should be implemented in another way.
(initialize): Default #:procedure to #f, and
s/compile-env/make-procedure/.
* module/oop/goops/compile.scm (code-table-lookup): Just return the
cmethod, not the entry -- since the entry is now just (append types
cmethod).
(compile-make-procedure): New procedure, returns a form that, when
evaluated/compiled, will yield a procedure of one argument, the
next-method. When called with a next-method, the procedure returns an
actual method implementation. compile-make-procedure returns #f if the
body doesn't call next-method.
(compile-method): Unify to always return procedures. Much cleaner and
*much* faster in the compiled case. In the interpreted case, there
might be a slight slowdown, but if there is one it should be slight.
* module/oop/goops/dispatch.scm (method-cache-install!): Adapt to removal
of compute-entry-with-cmethod.
* module/system/base/compile.scm (call-with-output-file/atomic): Close
the port we are writing to before renaming it, so that we flush output.
Might fix some 0-length write errors that Jao was seeing.
* module/system/base/syntax.scm (define-record): So, in the generated
constructors, allow optional arguments, but not keyword arguments.
Conses much less in the constructors.
(define-record/keywords): And the old define-record is here.
* module/language/ghil.scm (parse-ghil):
* module/language/ghil/compile-glil.scm (codegen):
* module/language/scheme/compile-ghil.scm (translate-1, quote)
(quasiquote): Don't use keywords in this compiler hotpath.
* module/system/base/language.scm (<language>):
* module/system/repl/common.scm (<repl>):
* module/system/vm/debug.scm (<debugger>): Use define-record/keywords.
* module/language/ghil.scm: Whoops, export some unquote-splicing
accessors that we didn't have exported before.
* module/system/base/syntax.scm: Speed up record-case, by syntactically
determining the predicates and accessors. Nasty, in a way; but also
much faster.
* module/system/base/pmatch.scm (ppat): Match atoms with eq?, not equal?.
This speeds up compilation considerably, as we never match against
numbers or strings or what-have-you. Note, you can match against
literals with equal? via quoting the literal in the pattern.
* module/language/ghil/compile-glil.scm (codegen): Record source location
for offset 0 into a lambda, if we can.
* module/language/scheme/compile-ghil.scm (translate-1)
(define-scheme-translator): In the retrans procedures, propagate the
location information from the enclosing expression if the subexpression
has no location information. Gives source information to many more
expressions.
(location): Just propagate the source properties as they are, the
glil->assembly compiler will interpret them.
* module/language/glil.scm (<glil>): Change glil-source to take "props"
and not "loc", as it's the source properties that we're interested in.
* module/language/glil/compile-assembly.scm (limn-sources): New function,
takes a list of addr-source property pairs and "compresses" them for
serialization to disk.
(glil->assembly): Limn the sources before writing them to disk. Avoid
non-tail recursion when determining total byte length of code.
* module/system/vm/program.scm (source:file, source:line, source:column):
Update for new source representation.
(program-source): Export.
(write-program): Nicer pretty-printing of anonymous procedures.
* libguile/backtrace.c (display_backtrace_get_file_line): Update for the
new VM source representation.
* libguile/programs.h:
* libguile/programs.c (scm_program_sources): Update for the new
serialized source representation, where the filename is not in the
stream unless it changes.
(scm_program_source): New exported function, looks up the source for a
given ip offset.
(scm_c_program_source): Update to return the last source information
that was <= the given IP, because we only serialize source info when it
changes.
* module/language/scheme/compile-ghil.scm (lookup-transformer): Allow
macros to be unquoted into the car of any form that results from macro
expansion. This lets modules export defmacros built on other defmacros
that are not exported.
* libguile/stacks.c (scm_make_stack): Instead of aborting when we misread
the number of stack frames, just print a warning. I'd like to figure
out what these cases are, exactly.
* module/language/scheme/compile-ghil.scm (lambda): Reindent the lambda
transformer.
* module/system/base/compile.scm (call-with-compile-error-catch): Write
the expression instead of displaying it.
(call-with-output-file/atomic): Don't actually redirect output to this
port, as it's not necessary -- the language-printer should respect the
port that we pass.
* libguile/frames.c (vm_frame_print): Add a frame printer.
* libguile/stacks.c (stack_depth, read_frames): Only switch the VM stack
for boot program dframes.
* libguile/vm-engine.c (VM_NAME): Push one debug frame per invocation,
unconditionally. (If we push them at all, of course.)
* libguile/programs.h (SCM_F_PROGRAM_IS_BOOT, SCM_PROGRAM_IS_BOOT): Flags
for determining if a program is a boot program. It turns out that our
heuristics e.g. in stacks.c would catch non-boot programs, like
programs that end with (goto/args 1), because the 1 is the same byte as
`halt'. That took a while to find...
* libguile/stacks.c (stack_depth, read_frames): Use the new boot prog
macros.
(scm_make_stack): Assert that we read the number of frames that we said
we would.
* libguile/vm.c (really_make_boot_program): Mark boot programs
appropriately.
* libguile/vm-engine.c (VM_PUSH_DEBUG_FRAMES): New knob, if true we much
with the scm_i_last_debug_frame when entering the VM, because sometimes
the evaluator doesn't do it for us.
(VM_ENGINE): Plug through debug frame fondling. Now, program exit comes
back to the main text. Rename err_args to finish_args, and reuse for
the return value.
* libguile/vm-engine.h (PUSH_LIST):
* libguile/vm-i-loader.c:
* libguile/vm-i-scheme.c:
* libguile/vm-i-system.c: Update for finish_args.
(halt): goto vm_done, now, instead of returning directly.
* libguile/eval.c (scm_call_0, scm_call_1, scm_call_2, scm_call_3)
(scm_call_4): Special-case compiled procedures here, to avoid consing.
* libguile/vm.h:
* libguile/vm.c (scm_c_vm_run): Take a SCM after all.
(scm_vm_apply, scm_load_compiled_with_vm): Adapt to vm_run change.
* libguile/programs.c (scm_make_program): Add a comment.
* libguile/vm-engine.h (INIT_ARGS): Add a couple of UNLIKELY notes.
* libguile/vm-i-system.c (make-closure): Inline the call to
scm_make_program, which avoids some redundant checks.
* libguile/vm-engine.c (VM_USE_HOOKS, VM_USE_CLOCK, VM_CHECK_EXTERNAL)
(VM_CHECK_OBJECT): Update to define these here, before including
vm-engine.h.
(vm_run): Change so that we can make different engines. Also, we take
an array of arguments, and the struct scm_vm directly, so as to avoid
any need to cons.
* libguile/vm-engine.h (CHECK_EXTERNAL, CHECK_OBJECT): Add some UNLIKELY
bits; don't seem to help.
* libguile/vm.c (vm_dispatch_hook): Change to not pass the VP. This needs
some love, and perhaps we revert to the old way.
(VM_ENGINE): Actually make two engines, vm_regular_engine and
vm_debug_engine. Probably there is room for improvement here. Actually
their speeds are the same at the moment.
(make_vm): Choose which engine to run; currently the debug engine by
default.
(scm_c_vm_run): A thin wrapper to invoke a VM without consing.
(scm_vm_apply): Use scm_c_vm_run.
(scm_load_compiled_with_vm): Use scm_c_vm_run.
* libguile/throw.c (scm_c_catch): Stash away the current vm's regs, and
restore them if there's a nonlocal exit. There is a terrible case we
have to handle if we catch from when the vm smob type isn't registered
but the throw has the vm registered, but I think we handle this fine.
* libguile/vm-engine.c (vm_run):
* libguile/vm-i-system.c (halt): Don't make a dynwind context, so that
entering the VM doesn't cons at all, except for the arg list. Maybe we
can fix that bit too.
* libguile/vm.c (vm_reset_stack): Remove, as there is no more dynwind.
(make_vm): Return #f if the tc16 hasn't yet been registered.
* libguile/instructions.c (fetch_instruction_table)
(scm_lookup_instruction_by_name): Rework so we lazily load instructions
into an array keyed by opcode, and a hash table keyed by symbolic name.
Much faster, in this hot spot of compilation.
* libguile/vm-engine.c (vm_run): Use malloc instead of scm_gc_malloc,
given that we aren't ever going to free this thing.
* libguile/vm-expand.h (VM_DEFINE_FUNCTION, VM_DEFINE_LOADER): Rework to
always be aliases to VM_DEFINE_INSTRUCTION.
(VM_DEFINE_INSTRUCTION): In the table case, update to work with
fetch_instruction_table().
* libguile/objects.c (scm_apply_generic): Inline the case when the
generic is a program.
* libguile/vm-i-system.c (return): Tick when functions return.
* module/oop/goops.scm (object-eqv?, object-equal?): Remove these
historical methods.
* module/system/vm/program.scm:
* libguile/programs.h:
* libguile/programs.c (scm_program_bindings, scm_program_bindings)
(scm_program_properties, scm_program_name): Unfortunately, implement
more procs in C, so that C can use them more easily.
* libguile/debug.c (scm_procedure_name): Dispatch to scm_program_name as
appropriate.
* libguile/vm-i-system.c (call): Tick in a call.
* libguile/vm-i-system.c (vector): Don't cons up a list just to make a
vector. Saves a couple percent in total cell allocation when loading
syncase. Probably not worth it, but foo!
* libguile/objcodes.c (scm_bytecode_to_objcode): Check that the length of
the vector matches the length embedded in the bytecode.
* libguile/programs.c (scm_program_meta): Call through to
scm_objcode_meta, instead of looking in the object table. Avoids
consing up a program+objcode slice for the meta until the meta is
actually called.
* libguile/vm-i-loader.c (load-program): Step past the metadata too.
* module/language/glil/compile-assembly.scm (make-meta): Just return the
load-program form, or #f.
(assoc-ref-or-acons, object-index-and-alist, make-object-table): Don't
write the meta into the object table.
(glil->assembly): Instead write the meta into the load-program form.
