* libguile/stacks.c:
* libguile/strings.c:
* libguile/throw.c:
* libguile/vm.c: Use scm_from_latin1_symboln to make symbols from string
literals, because they aren't in the user's locale -- they are in
ASCII, and we can optimize this case.
* libguile/vm-i-loader.c: Also use scm_from_latin1_symboln when loading
narrow symbols.

* libguile/programs.c (scm_program_source): Add an optional arg, the
sources table to traverse. Defaults to the result of
scm_program_sources.
* module/system/vm/program.scm (program-sources-pre-retire): Move
definition here from (system vm traps), and export.
* module/system/vm/traps.scm: Adapt.

returns the source line corresponding to the next instruction instead
of the previous instruction.

function, will replace (procedure-property foo 'arity).
* libguile/programs.c (scm_i_program_arity): Rework to always provide
the most permissive arity.
* libguile/programs.h:
* libguile/programs.c (scm_program_name): Remove. procedure-name is
sufficient.

* libguile/procprop.c (scm_procedure_properties): Use
scm_i_program_properties, for programs.

(object-stexi-documentation): Use procedure-property, not
program-property.
* libguile/Makefile.am (lib_LTLIBRARIES): Instead of just "libguile.la",
make "libguile-@EFFECTIVE_VERSION@.la". This allows multiple versions
of Guile to be installed at once. See
http://www106.pair.com/rhp/parallel.html for a rationale.
(libguile_@GUILE_EFFECTIVE_VERSION@_la_CFLAGS):
(libguile_@GUILE_EFFECTIVE_VERSION@_la_SOURCES):

Guile, use the effective version also.
* meta/guile-2.0-uninstalled.pc.in (Libs):
* meta/guile-2.0.pc.in (Libs): Use -lguile-@EFFECTIVE_VERSION@. This
change should mean that code built against Guile should not be
affected by the libguile rename.

* libguile/programs.c (scm_i_program_print): Instead of printing the
address of the objcode, print the address of the program itself. Also
for continuations.
* libguile/vm-i-system.c (continuation-call): New op, like subr-call or
foreign-call, but for continuations.
* libguile/continuations.h: Add scm_i_continuation_call internal
declaration.
(SCM_CONTINUATIONP): Reimplement in terms of
SCM_PROGRAM_IS_CONTINUATION.
(scm_tc16_continuation, SCM_CONTREGS, SCM_CONTINUATION_LENGTH)
(SCM_SET_CONTINUATION_LENGTH, SCM_JMPBUF, SCM_DYNENV, SCM_THROW_VALUE)
(SCM_CONTINUATION_ROOT, SCM_DFRAME): Remove these from the exposed
API.
(scm_i_continuation_to_frame): New internal declaration.
* libguile/continuations.c
* libguile/continuations.c: Add trickery like in foreign.c, smob.c, and
gsubr.c, so that we can make procedural trampolines for continuations.
(scm_i_continuation_to_frame): New internal function, from stacks.c.
* libguile/programs.h (SCM_F_PROGRAM_IS_CONTINUATION)
(SCM_PROGRAM_IS_CONTINUATION): Add a flag for programs that are
continuations. Probably should add flags for the other trampoline
types too.
* libguile/programs.c (scm_i_program_print): Print continuations as
before.
* libguile/stacks.c (scm_stack_id, scm_make_stack): Use
scm_i_continuation_to_frame in the continuation case.
* libguile/_scm.h (SCM_OBJCODE_MINOR_VERSION): Bump.
* libguile/programs.h (SCM_PROGRAM_FREE_VARIABLES)
(SCM_PROGRAM_FREE_VARIABLE_REF, SCM_PROGRAM_FREE_VARIABLE_SET)
(SCM_PROGRAM_NUM_FREE_VARIABLES):
* libguile/programs.c (scm_make_program, scm_program_num_free_variables)
(scm_program_free_variable_ref, scm_program_free_variable_set_x):
Allocate free variables inline with programs, instead of being in a
vect. Should improve locality, and require fewer local variables in
the VM.
* libguile/vm-engine.c (vm_engine): Remove free_vars and free_vars_count
variables.
* libguile/vm-engine.h (CACHE_PROGRAM): No need to muck with free_vars
and free_vars_count.
(CHECK_FREE_VARIABLE): Update for inline free vars.
* libguile/vm-i-system.c (FREE_VARIABLE_REF): Update for inline free
vars.
(make-closure, fix-closure): Take the closure vals as separate stack
args, and copy or fix them inline into the appropriate closure.
* module/language/objcode/spec.scm (program-free-variables): Define a
local version of this removed function.
* module/language/tree-il/compile-glil.scm (flatten): Adjust to not make
a vector when making closures.
* module/system/vm/program.scm: Export program-num-free-variables,
program-free-variable-ref, program-free-variable-set!, and remove
program-free-variables.
* test-suite/tests/tree-il.test ("lambda"): Update to not make vectors
when making closures.
* libguile/Makefile.am (modinclude_HEADERS):
* libguile/vm-bootstrap.h: Remove vm-bootstrap.h.
* libguile/frames.c: No more vm-bootstrap.h.
* libguile/instructions.c (scm_init_instructions):
* libguile/objcodes.c (scm_init_objcodes):
* libguile/programs.c (scm_init_programs): No need to call
scm_bootstrap_vm, init.c does that for us.
* libguile/vm.c (scm_bootstrap_vm): No need call e.g.
scm_bootstrap_frames, init.c does that. Remove a twice-calling guard,
should be unnecessary. Don't define the load-compiled subr here.
* libguile/load.c (scm_init_load): Define the load-compiled subr here.
* libguile/vm.h: Declare scm_bootstrap_vm here.
* libguile/init.c (scm_i_init_guile): Properly integrate VM
bootstrapping into this file.
* libguile/programs.c (scm_program_meta): Give the program meta
procedure the same object table as the main procedure. Will allow for
easier hand-crafting of meta programs. Of course when compiling a
metadata procedure from Scheme, one still wants to avoid preallocating
the heap objects needed by the metadata...
* libguile/frames.c, libguile/objcodes.c, libguile/programs.c,
libguile/vm-engine.c, libguile/vm-i-system.c, libguile/vm.c: Use
`SCM_C_OBJCODE_BASE ()' instead of accessing the `base' field of
`struct scm_objcode'.
* libguile/objcodes.h (struct scm_objcode)[base]: Remove.
* libguile/frames.c, libguile/instructions.c, libguile/objcodes.c,
libguile/programs.c, libguile/throw.c, libguile/vm-i-scheme.c,
libguile/vm.c: Replace uses of discouraged constructs by their
current counterparts.
* module/language/glil/compile-assembly.scm (open-arity, close-arity)
(begin-arity, glil->assembly): Refactor so that arities can have
noncontiguous starts and ends. So within a prelude there is no arity
-- only before (the previous arity) or after (the new arity).
* module/system/vm/program.scm (arity:end): Add this private accessor.
Arities are expected to be in the new format. While not a change in
objcode format, it is an incompatible change, so I'll bump the objcode
cookie.
(program-arity): Check that the ip is within both bounds of the arity.
* libguile/_scm.h (SCM_OBJCODE_MINOR_VERSION): Bump.
* libguile/programs.c (scm_i_program_arity): Update for new arity format.
* module/system/vm/frame.scm (vm-frame-arguments): Avoid throwing an
error in this function, which is called from the backtrace code.
* 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.
* 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/tags.h (scm_tc7_program):
* libguile/programs.h: Programs now have their own tc7 code. Fix up the
macros appropriately.
* libguile/programs.c: Remove smobby bits, leaving marking, printing,
and application for other parts of Guile.
* libguile/debug.c (scm_procedure_source):
* libguile/eval.c (scm_trampoline_0, scm_trampoline_1)
(scm_trampoline_2): Add cases for tc7_program.
* libguile/eval.i.c (CEVAL, SCM_APPLY):
* libguile/evalext.c (scm_self_evaluating_p):
* libguile/gc-card.c (scm_i_sweep_card, scm_i_tag_name):
* libguile/gc-mark.c (1):
* libguile/print.c (iprin1):
* libguile/procs.c (scm_procedure_p, scm_thunk_p)
* libguile/vm-i-system.c (make-closure): Adapt to new procedure
representation.
* libguile/procprop.c (scm_i_procedure_arity): Do the right thing for
programs.
* test-suite/tests/procprop.test ("procedure-arity"): Arity test now
succeeds.
* libguile/goops.c (scm_class_of): Programs now belong to the class
<procedure>, not a smob class.
* libguile/vm.h (struct vm, struct vm_cont):
* libguile/vm-engine.c (vm_engine):
* libguile/frames.h (SCM_FRAME_BYTE_CAST, struct vm_frame):
* libguile/frames.c (scm_c_make_vm_frame): Fix usages of scm_byte_t,
changing them to scm_t_uint8.
* libguile/programs.h:
* libguile/programs.c: (SCM_PROGRAM_FREE_VARIABLES): Rename from
SCM_PROGRAM_FREE_VARS. Callers changed.
* libguile/programs.c (scm_make_program): Rename arg to
"free_variables".
(scm_program_free_variables): Rename from program-free-vars.
* libguile/vm-engine.h:
* libguile/vm-engine.c (VM_CHECK_FREE_VARIABLES): Rename from
VM_CHECK_CLOSURE.
(vm_engine, CACHE_PROGRAM): Rename closure and closure_count to free_vars and
free_vars_vount.
* libguile/vm-i-system.c (FREE_VARIABLE_REF): Rename from CLOSURE_REF.
(free-ref, free-boxed-ref, free-boxed-set): Rename from closure-ref,
closure-boxed-ref, closure-boxed-set.
(make-closure): Renamed from make-closure2.
* module/language/glil/compile-assembly.scm (glil->assembly): Hack to
never write out the the old "make-closure" instruction. Will fix
better later. Change to emit free-ref etc instead of closure-ref.
* module/language/tree-il/compile-glil.scm (flatten): Emit make-closure
instead of make-closure2, now that the old make-closure is gone.
* module/system/vm/program.scm (system): Rename program-free-vars to
program-free-variables.
* test-suite/tests/tree-il.test ("lambda"): Update for make-closure.
* libguile/frames.c (scm_frame_external_link): Removed.
* libguile/frames.h: No need to have the "external link" in the stack
frame -- update macros to take the new situation into account.
* libguile/objcodes.h (struct scm_objcode): Rename the nexts field to
"unused". In the future we can use it for nlocs, I think.
(SCM_OBJCODE_NEXTS): removed.
* libguile/programs.h:
* libguile/programs.c (scm_make_program): Expect the third argument to
be a vector of free variables, not a list of free variables.
SCM_BOOL_F indicates no free variables, not SCM_EOL.
(program_mark): Adapt.
(scm_program_arity): No more nexts.
(scm_program_free_vars): Replaces scm_program_externals.
* libguile/vm-engine.c (VM_CHECK_EXTERNAL)
(vm_engine): No need for the "external" var.
* libguile/vm-engine.h (CACHE_PROGRAM): Update for SCM_PROGRAM_FREE_VARS
instead of SCM_PROGRAM_EXTERNALS.
(NEW_FRAME): Update for new frame size, and no need to cons up
externals. Yay :)
* libguile/vm-i-loader.c (load-program): Update for scm_make_program.
* libguile/vm-i-system.c (external-ref, external-set): No more.
(make-closure): No more.
(goto/args): No need to re-cons externals here. Update for new stack
frame size.
(mv-call, return, return/values): Update for new frame size. No need
to reinstate externals on return.
* libguile/vm.c (really_make_boot_program, scm_load_compiled_with_vm):
Update for scm_make_program.
* module/language/objcode/spec.scm (objcode-env-externals): Treat '() as
#f, for the externals. Need to clean this up later...
* module/system/vm/program.scm (arity:nexts): Remove. Rename
program-external to program-free-vars.
* libguile/frames.c:

* libguile/vm-expand.h:
* libguile/vm-i-scheme.c:
* libguile/vm.c:
* libguile/vm.h: Update to use SCM_API and SCM_INTERNAL correctly. Adjust
copyright to be the same as the copyright of Guile itself, which should
be fine given that the FSF holds the whole thing.
Reported by Daniel Kraft <d@domob.eu>.
* libguile/frames.c, libguile/vm.c: Include <stdlib.h>, use `size_t'
instead of `scm_sizet'.
* libguile/objcodes.c, libguile/programs.c, libguile/vm-engine.c,
libguile/vm-i-loader.c, libguile/vm-i-system.c: Use `scm_list_X ()'
instead of the deprecated `SCM_LISTX ()'.
* libguile/extensions.h: Define a scm_t_extension_init_func.
* libguile/frames.c:
* libguile/instructions.c:
* libguile/objcodes.c:
* libguile/programs.c:
* libguile/vm.c: Register extension init funcs. Should play nicer with a
static Guile, in addition to working on Darwin with non-default
installation prefixes without munging DYLD_LIBRARY_PATH.
* module/system/vm/frame.scm:
* module/system/vm/instruction.scm:
* module/system/vm/objcode.scm:
* module/system/vm/program.scm:
* module/system/vm/vm.scm: Use load-extension.
* guile-tools.in: Fix the checks to account for non-srcdir builds.
* libguile/frames.c:
* libguile/objcodes.c:
* libguile/programs.c:
* libguile/instructions.c:
* libguile/vm.c: Fix snarf-includes to cope with non-srcdir builds.
* libguile/instructions.h:
* libguile/instructions.c: Fix the stubs inclusion to be non-srcdir
compatible.
* libguile/vm-expand.h (VM_DEFINE_INSTRUCTION): Fix some things so as not
to require the instructions.h defintitions, since we have the codes
already. Not important tho :)
* pre-inst-guile-env.in: Minor tweak that should have no effect.
* test-suite/standalone/Makefile.am (all-local): Remove a chmod +x step,
the configure.ac rule should do that if necessary.
* 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.
* 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.
* 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/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.
* gdbinit: Untested attempts to get the stack fondling macros to deal
with the new program representation.
* libguile/frames.c (scm_vm_frame_arguments, scm_vm_frame_source)
(scm_vm_frame_local_ref, scm_vm_frame_local_set_x): SCM_PROGRAM_DATA is
a struct scm_objcode*.
* libguile/instructions.h:
* libguile/instructions.c: Hide the instruction table and the struct
scm_instruction structure; all access to instructions now goes through
procedures. This is because instructions are no longer in a packed
array indexed by opcode. Also, declare a mask that all instructions
should fit in.
* libguile/objcodes.h:
* libguile/objcodes.c: Rewrite so that object code directly maps its
arity and length from its bytecode. This makes it unnecessary to keep
this information in programs, allowing programs to be simple conses
between the code (objcodes) and data (the object table and the closure
variables).
* libguile/programs.c (scm_make_program): Rework so that make-program
takes objcode, an object table, and externals as arguments. It's much
clearer this way, and we avoid malloc().
* libguile/stacks.c (is_vm_bootstrap_frame): Update for program/objcode
changes.
* libguile/vm-engine.c (vm_run): Initialize the jump table on the first
run, with the opcodes declared in the instruction sources, and with bad
instructions raising an error instead of wandering off into the
Unknown.
* libguile/vm-engine.h (FETCH_LENGTH): Always represent lengths as 3
bytes. The old code was too error-prone.
(NEXT_JUMP): Mask the instruction with SCM_VM_INSTRUCTION_MASK.
(NEW_FRAME): Update for program/objcode changes.
* libguile/vm-expand.h (VM_DEFINE_FUNCTION, VM_DEFINE_INSTRUCTION)
(VM_DEFINE_LOADER): Update so that we explicitly specify opcodes, so
that we have a stable bytecode API.
* libguile/vm-i-loader.c: Update license to LGPLv2+. Explicitly declare
opcodes.
(load-integer): Use an int instead of a long as the accumulator; still
need to revisit this code at some point, I think.
(load-program): Simplify, thankfully!! Just creates the objcode slice
and rolls with it.
* libguile/vm-i-scheme.c: Number the opcodes explicitly.
* libguile/vm-i-system.c: Update license to LGPLv2+. Explicitly declare
opcodes.
(make-closure): Update for new program API.
* libguile/vm.c (vm_make_boot_program): Update for new program/objcode
API. Still a bit ugly.
(scm_load_compiled_with_vm): Update for new program/objcode API.
* module/language/assembly.scm (byte-length): Fix byte-length calculation
for loaders, and load-program.
(code-pack, code-unpack): Start to move things from (system vm conv)
here.
(object->code, code->object): More things from conv.scm.
* module/language/glil.scm (<glil-program>): Add a new field,
closure-level.
(make-glil-program, compute-closure-level): Calculate the "closure
level" when making a glil program. This is the maximum depth of
external binding refs in this closure.
(unparse-glil): Fix label serialization.
* module/language/glil/compile-assembly.scm (make-meta): Prepend #f for
the meta's object table, though maybe in the future we can avoid
creating assembly in the first place.
(assoc-ref-or-acons, object-index-and-alist): GRRR! Caught again by the
different sets of arguments to assoc and assoc-ref!
(glil->assembly): Attempt to make the <glil-program> case more
readable, and fix the bugs. Sorry I don't know how to comment this
change any more than this.
(glil->assembly): For <glil-module> serialize the whole key, not just
the name.
(dump-object): subprogram-code is already a list. Serialize integers as
strings, not u8vectors. Fix the order of lists and vectors.
* module/language/glil/spec.scm (glil): Switch orders, so we prefer glil
-> assembly -> objcode. Actually glil->objcode doesn't work any more,
needs to be removed I think.
* module/language/objcode/spec.scm (objcode->value):
s/objcode->program/make-program/.
* module/language/scheme/inline.scm: Add acons inline.
* module/system/vm/conv.scm (make-byte-decoder): Skip the first 8 bytes,
they are header. Handle subprograms properly. Still needs help though.
(decode-length): Lengths are always 3 bytes now.
* module/system/vm/disasm.scm: Superficial changes to keep things
working. I'd like to fix this better in the future.
* module/system/vm/frame.scm (bootstrap-frame?): Fixes for
program-bytecode.
* module/system/vm/program.scm: Export make-program. It's program-objcode
now, no more program-bytecode.
* module/system/vm/vm.scm (vm-load): Use make-program.
* test-suite/tests/asm-to-bytecode.test: New test, very minimal.
* module/system/vm/objcode.scm: Export word-size, byte-order, and
write-objcode.
* libguile/programs.h (struct scm_program): Remove the module and meta
fields.
* libguile/programs.c (scm_c_make_program): Add a new argument, `objs'.
If it's a vector, we'll look for the module and the metadata in there,
instead of having them in the scm_program structure.
(scm_c_make_closure, program_mark, scm_program_meta)
(scm_c_program_source, scm_program_module): Adapt to the new program
representation.
* libguile/objcodes.c (scm_objcode_to_program): Pass #f as the object
table when making the program.
* libguile/vm-engine.h (CACHE_PROGRAM):
* libguile/vm-engine.c (vm_run): Rework to use the simple vector API for
getting the current object table. Call the helper,
vm_make_boot_program, to make the boot program.
* libguile/vm-i-loader.c (load-program): Set the current module and the
meta in the object vector, which we pass to scm_c_make_program.
* libguile/vm-i-system.c (toplevel-ref, toplevel-set): Adapt to the new
program representation.
* module/language/glil/compile-objcode.scm (codegen): Clarify.
* libguile/programs.c (scm_c_make_closure): If the program is actually
not a program, abort. This can happen if GC misses a reference, as
currently seems to happen.
* libguile/vm.c (vm_mark): Revert part of
7ff017002d, which changed the call to
scm_mark_locations. I'm 99% *sure* this is wrong, but it seems to
prevent missed references when recompiling the .go files in guile
itself. Needs revisiting soon, but for the time being we can go back to
where we were a couple of days ago.
* libguile/vm-i-system.c (halt, vector, vector-mark): Sync the registers
before calling into C, as it may GC.
* libguile/programs.c (program_print): Only try to lookup write-program
if the module system is booted.
* libguile/vm-engine.h (FREE_FRAME): Remove, it's now inlined everywhere.
* libguile/vm-i-system.c (tail-call): Inline FREE_FRAME, and implement
the calling bits here. Will make things more hackable.
* module/system/vm/program.scm (program-bindings-as-lambda-list): Handle
the bindings-is-null case too -- not sure how it comes about, though. A
thunk with no let, perhaps.
(write-program): Another default for the name: the source location at
which it was defined.
* libguile/programs.c (program_print): Add some "logic" to stop doing
detailed prints if one print had a nonlocal exit -- preventing
exceptions in backtraces.
* module/system/vm/frame.scm (frame-call-representation)
(frame-program-name): Rename program-name to frame-program-name, and
use the program-name if it is available.
* module/system/vm/program.scm (program-bindings): Return #f if there are
no bindings.
(program-name): New public procedure.
(program-bindings-as-lambda-list, write-program): A more useful writer
for programs.
* libguile/programs.c (scm_bootstrap_programs, program_print): Add a smob
printer for programs, which dispatches to `write-program'.
* libguile/programs.h (struct scm_program):
* libguile/programs.c (scm_c_make_program): Record the current module
when making a program. This replaces the per-late binding recorded
module in the generated code, which should be more efficient, both in
terms of garbage, and in not calling resolve-module.
(program-module): New accessor.
* module/system/vm/program.scm: Add program-module to exports.
* libguile/vm-i-loader.c (link-later): Remove this instruction, since now
the entry in the object table is just a symbol, and can be loaded with
load-symbol.
* libguile/vm-i-system.c (late-variable-ref, late-variable-set): Rework
so as to look up in the module of the current program. The logic could
be condensed quite a bit if scm_module_lookup () knew what to do with
mod==#f.
* module/system/vm/assemble.scm (dump-object!): Dump <vlink-later> just
as load-symbol, as mentioned in the note on link-later.
* module/system/il/ghil.scm: Update comment to reflect the new reality.
* ice-9/boot-9.scm: Only define load-compiled as #f if it's not already
defined, which won't normally be the case.
* libguile/guile-vm.c: Removed, there's no more guile-vm binary.
* libguile/frames.c: (with change frame? -> heap-frame?)
* libguile/frames.h:
* libguile/instructions.c:
* libguile/instructions.h:
* libguile/objcodes.c:
* libguile/objcodes.h:
* libguile/programs.c:
* libguile/programs.h:
* libguile/vm-bootstrap.h: (was bootstrap.h)
* libguile/vm-engine.c: (was vm_engine.c)
* libguile/vm-engine.h: (was vm_engine.h)
* libguile/vm-expand.h: (was vm_expand.h)
* libguile/vm-i-loader.c: (was vm_loader.c)
* libguile/vm-i-scheme.c: (was vm_scheme.c)
* libguile/vm-i-system.c: (was vm_system.c)
* libguile/vm.c:
* libguile/vm.h: These files moved here from src/, as guile-vm is now a
part of libguile.
* libguile/init.c: Bootstrap the VM. Yay!
* libguile/Makefile.am: The necessary chicanery here.
* module/system/vm/Makefile.am:
* module/system/vm/bootstrap.scm:
* module/system/vm/frame.scm:
* module/system/vm/instruction.scm:
* module/system/vm/objcode.scm:
* module/system/vm/program.scm:
* module/system/vm/vm.scm:
* pre-inst-guile-env.in: Add builddirs to the load path; add module/ to
the path in the empty-$GUILE_LOAD_PATH case as well.
* src/Makefile.am: Moved out everything except guilec and guile-disasm,
which probably should be moved to the scripts directory?
* testsuite/Makefile.am: Update to find guile-vm in the right place.
* module/system/vm/Makefile.am:
* module/system/vm/bootstrap.scm: Removed bootstrap.scm, scm_init_guile
handles the bootstrapping for us.
* module/system/vm/frame.scm:
* module/system/vm/instruction.scm:
* module/system/vm/objcode.scm:
* module/system/vm/program.scm:
* module/system/vm/vm.scm: Call the init functions in libguile; should
fix at some point to avoid the dlopen?
