1dcf33280d procedure-arity on vm-compile apply: verily, unresolved.
* test-suite/tests/procprop.test ("procedure-arity"): Procedure-property
  'arity on "apply" will fail if "apply" is a program. I suggest that
  procedure-property is actually the wrong interface for this; if we even
  want to preseve the old arity forms, we should have an accessor for
  arity directly that the VM can implement. But in the meantime throw
  this nasty error while we decide.

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.

b0b180d522 nifty generic compiler infrastructure -- no more hardcoded passes
* module/system/base/language.scm (<language>): Rework so that instead of
  hardcoding passes in the language, we define compilers that translate
  from one language to another. Add `parser' to the language fields, a
  bit of a hack but useful for languages with s-expression external
  representations but with record internal representations.
  (define-language, *compilation-cache*, invalidate-compilation-cache!)
  (compute-compilation-order, lookup-compilation-order): Add an algorithm
  that does a depth-first search for a translation path from a source
  language to a target language, caching the result in a lookup table.

* module/language/scheme/spec.scm:
* module/language/ghil/spec.scm: Update to the new language format.

* module/language/glil/spec.scm: Add a language specification for GLIL,
  with a compiler to objcode. Also there are parsers and printers, for
  repl usage, but for some reason this doesn't work yet.

* module/language/objcode/spec.scm: Define a language specification for
  object code. There is some sleight of hand here, in the "compiler" to
  values; but there is method behind the madness, because this way we
  higher levels can pass environments (a module + externals pair) to
  objcode->program.

* module/language/value/spec.scm: Define a language specification for
  values. There is something intellectually dishonest about this, but it
  does serve its purpose as a foundation for the language hierarchy.

* configure.in:
* module/language/Makefile.am
* module/language/ghil/Makefile.am
* module/language/glil/Makefile.am
* module/language/objcode/Makefile.am
* module/language/value/Makefile.am:
  Autotomfoolery for the ghil, glil, objcode, and value languages.

* module/language/scheme/translate.scm (translate): Import the bits that
  understand `compile-time-environment' here, and pass on the relevant
  portions of the environment to the next compiler pass.

* module/system/base/compile.scm (current-language): New procedure, refs
  the current language fluid, or lazily sets it to scheme.
  (call-once, call-with-output-file/atomic): Refactor these bits to use
  with-throw-handler. No functional change.
  (compile-file, compile-and-load, compile-passes, compile-fold)
  (compile): Refactor the public interface of the compiler to be generic
  and simple. Uses `lookup-compilation-order' to find a path from the
  source language to the target language.

* module/system/base/syntax.scm (define-type): Adapt to changes in
  define-record.
  (define-record): Instead of expecting all slots in the first form,
  expect them in the body, and let the first form hold the options.

* module/system/il/compile.scm (compile): Adapt to the compilation pass
  API (three in and two out).

* module/system/il/ghil.scm (<ghil-var>, <ghil-env>)
  (<ghil-toplevel-env>): Adapt to define-record changes.

* module/system/il/glil.scm (<glil-vars>): Adapt to define-record
  changes.
  (<glil>, print-glil): Add a GLIL record printer that uses unparse.
  (parse-glil, unparse-glil): Update unparse (formerly known as pprint),
  and write a parse function.

* module/system/repl/common.scm (<repl>): Adapt to define-record changes.
  (repl-parse): New function, parses the read form using the current
  language. Something of a hack.
  (repl-compile): Adapt to changes in `compile'.
  (repl-eval): Fix up the does-the-language-have-a-compiler check for
  changes in <language>.

* module/system/repl/repl.scm (start-repl): Parse the form before eval.

* module/system/repl/command.scm (describe): Parse.
  (compile): Be more generic.
  (compile-file): Adapt to changes in compile-file.
  (disassemble, time, profile, trace): Parse.

* module/system/vm/debug.scm:
* module/system/vm/assemble.scm: Adapt to define-record changes.

* module/language/scheme/translate.scm (receive): Fix an important bug
  that gave `receive' letrec semantics instead of let semantics. Whoops!

This reverts par of "Document the failure of `gc.test' wrt. unused modules."
(commit 328efeb9a6.)

* ice-9/boot-9.scm (set-module-eval-closure!): Don't set the `module' property

* libguile/modules.c (scm_lookup_closure_module): Call `abort ()' to make it

3fd8807eab make-procedure-with-setter inherits name from getter

  srfi-17 test, as the VM doesn't set procedure-name on define -- but
  perhaps that is the bug that should be fixed. In any case this patching
  is cheap.

* test-suite/tests/eval.test: Change so that (define name pws) is

  (make-bound-check-get, make-get, make-set): Compile these indexed
  accessors instead of having them be closures. Probably slower for the
  memoizer, but faster for the vm... not sure what the perfect solution
  is.

* test-suite/tests/goops.test ("defining classes"): Add a test that

  that (@ (system base compile) compile) thing).

3de80ed52f recompiling with compile environments, fluid languages, cleanups
* ice-9/boot-9.scm (compile-time-environment): Remove definition from
  boot-9 -- instead, autoload it and `compile' from (system base
  compile).

* libguile/objcodes.h:
* libguile/objcodes.c (scm_objcode_to_program): Add an optional argument,
  `external', the external list to set on the returned program.

* libguile/vm-i-system.c (externals): New instruction, returns the
  external list. Only used by (compile-time-environment).

* libguile/vm.c (scm_load_compiled_with_vm): Adapt to
  scm_objcode_to_program change.

* module/language/scheme/translate.scm (translate): Actually pay
  attention to the environment passed as an argument.
  (custom-transformer-table): Expand out (compile-time-environment) to
  something that can be passed to `compile'.

* module/system/base/compile.scm (*current-language*): Instead of
  hard-coding `scheme' in various places, use a current language fluid,
  initialized to `scheme'.
  (compile-file, load-source-file): Adapt to *current-language*.
  (load-source-file): Ada
  (scheme-eval): Removed, no one used this.
  (compiled-file-name): Don't hard-code "scm" and "go"; instead use the
  %load-extensions and %load-compiled-extensions.
  (cenv-module, cenv-ghil-env, cenv-externals): Some accessors for
  compile-time environments.
  (compile-time-environment): Here we define (compile-time-environment)
  to something that will return #f; the compiler however produces
  different code as noted above.
  (compile): New function, compiles an expression into a thunk, then runs
  the thunk to get the value. Useful for procedures. The optional second
  argument can be either a module or a compile-time-environment; in the
  latter case, we can recompile even with lexical bindings.
  (compile-in): If the env specifies a module, set that module for the
  duration of the compilation.

* module/system/base/syntax.scm (%compute-initargs): Fix a bug where the
  default value for a field would always replace a user-supplied value.
  Whoops.

* module/system/il/ghil.scm (ghil-env-dereify): New function, takes the
  result of ghil-env-reify and turns it back into a GHIL environment.

* scripts/compile (compile): Remove some of the tricky error handling, as
  the library procedures handle this for us.

* test-suite/tests/compiler.test: Add a test for the dynamic compilation
  bits.

* libguile/vm.c (vm_cont_mark): Fix the marking function.
  (vm_mark): Fix this one too -- the size is a number of STACKITEMS,
  which we foolishly assume are the same size as SCM.

* test-suite/tests/ftw.test: Make our stat hacks verifyable without
  assuming that they are interpreted.

* test-suite/tests/r5rs_pitfall.test: Re-indent.

fb2f8886c4 Make literal strings (i.e., returned by `read') read-only.
* libguile/read.c (scm_read_string): Use `scm_i_make_read_only_string ()' to
  return a read-only string, as mandated by R5RS.  Reported by Bill
  Schottstaedt <bil@ccrma.Stanford.EDU>.

* libguile/strings.c (scm_i_make_read_only_string): New function.
  (scm_i_shared_substring_read_only): Special-case the empty string
  so that the read-only and read-write empty strings are `eq?'.  This
  optimization is relied on by the `substring/shared' `empty string'
  test case in `srfi-13.test'.

* libguile/strings.h (scm_i_make_read_only_string): New declaration.

* test-suite/tests/strings.test ("string-set!")["literal string"]: New test.

* NEWS: Update.

fd2b17b9cb Make `symbol->string' return a read-only string.
* libguile/strings.c (scm_i_symbol_substring): Return a read-only string
  since R5RS requires `symbol->string' to return a read-only string.
  Reported by Bill Schottstaedt <bil@ccrma.Stanford.EDU>.

* test-suite/tests/symbols.test: Add `define-module' clause.
  (exception:immutable-string): Adjust to current exception.
  ("symbol->string")["result is an immutable string"]: Use
  `pass-if-exception' instead of `expect-fail-exception'.

* NEWS: Update.

  to ensure that result is non-negative.
