c4c098e355 procedure-properties for RTL functions
* module/system/vm/assembler.scm (link-procprops, link-objects): Arrange
  to write procedure property links out to a separate section.

* module/system/vm/debug.scm (find-program-properties): Wire up
  procedure-properties for RTL procedures.  Yeah!  Fistpumps!  :)

* module/system/vm/debug.scm (find-program-debug-info): Return #f if the
  string is "", as it is if we don't have a name.  Perhaps
  elf-symbol-name should return #f in that case...

* libguile/procprop.h:
* libguile/procprop.c (scm_procedure_documentation): Move here from
  procs.c, and to make the logic more similar to that of procedure-name,
  which allows RTL programs to dispatch to rtl-program-documentation.

  narrow symbols.

  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.

44602b0868 rename libguile to libguile-@EFFECTIVE_VERSION@, currently libguile-2.0
* 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):

* module/system/vm/objcode.scm:

  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.

* guile-readline/Makefile.am (libguilereadline_v_@LIBGUILEREADLINE_MAJOR@_la_LIBADD):

1d1cae0e2e continuations are vm procedures
* 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.

6f16379e9a allocate free variables inline to closures
* 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.

a6029b97ea properly integrate vm bootstrapping into init.c
* 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.

31a26df2cc program-meta procedures get their program's objtable
* 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.

df435c8307 arities can have noncontiguous starts and ends
* 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.

56164a5a6c de-nargs struct scm_objcode; procedure-property refactor
* 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.

6c6a44390b runtime and debugging support for callee-parsed procedure args
* 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/eval.c (scm_trampoline_0, scm_trampoline_1)
  (scm_trampoline_2): Add cases for tc7_program.

  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):

  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.

20d47c3915 remove "externals" from the vm
* 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.

  Update for scm_make_program.
* module/language/objcode/spec.scm (objcode-env-externals): Treat '() as

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 ()'

* libguile/frames.c:
* libguile/instructions.c:
* libguile/objcodes.c:
* libguile/programs.c:
* libguile/vm.c: Register extension init funcs. Should play nicer with a

aeeff258c6 non-srcdir build fixes
* 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.

df8cd091f9 provide program apply_0, apply_1, apply_2 implementations
* libguile/programs.c (program_apply_0, program_apply_1)

  smob application procedures. This molests some internal interfaces, but
  hey, we're internal.

028e3d0666 propagate much more source info through compilation
* 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:

  (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.

ac47d5f639 avoid 8 words of allocation per lambda, whoooo
* 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.

53e28ed9b2 static opcodes; refactor program/objcode division; use new assembly pipeline
* 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.

2fda024221 move module and meta inside programs' object tables
* 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.

877ffa3f9c revert part of 7ff017002d that caused missed references
* 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/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.

0ba8bb7143 tweaks for printing programs
* 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.

e6fea61823 programs can now get at their names, and print nicely
* 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'.

8e3670748f rework late binding resolution to be simpler and more efficient
* 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.

83495480e8 merge guile-vm into libguile itself
* ice-9/boot-9.scm: Only define load-compiled as #f if it's not already

* libguile/frames.c: (with change frame? -> heap-frame?)

* 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.

  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?

* module/system/vm/Makefile.am:
* module/system/vm/bootstrap.scm: Removed bootstrap.scm, scm_init_guile
