e311f5fa04 tick in calls, procedure-name works on compiled procedures
* 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.

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.

9a9f64874a add scm_c_program_source
* libguile/programs.h:
* libguile/programs.c (scm_c_program_source): New helper for getting
  source information from C.

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
  defined, which won't normally be the case.

* libguile/frames.h:
* libguile/instructions.c:
* libguile/instructions.h:
* libguile/objcodes.c:
* libguile/objcodes.h:

* 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?
