e610dc3851 merge guile-vm to guile
An attempt to pull in the original history from guile-vm into guile itself.

87c4242ca8 Updated loop disassembly
* benchmark/lib.scm: Update loop disassembly, with inlining. Neat!
2008-05-25 13:43:26 +02:00
Andy Wingo
6cc3f99e83 add inline macros for zero? and 1-
* module/system/il/inline.scm (zero?, 1-): New inlines. Neat :) The loop
  benchmark speedup is now up to 5x.

e677365cbc Speed up the self-tail-recursive case (1x->2x)
* benchmark/lib.scm: Add a comment, update the loop disassembly. Loop is
  now faster in the VM, thankfully.

* src/vm_engine.h (CACHE_PROGRAM): Only release and regrab the object
  array handle if the program changed. That is to say, optimize the
  self-tail-recursive case. But perhaps the thing to optimize here are
  the procedure calls themselves. Worth looking at in the future.

22bcbe8cc9 enable inlining; speed!
* module/system/il/inline.scm: New module, implements generic inlining of
  scheme functions. It even does the right thing regarding (define
  arity:nopt caddr) and such. So now there are many more inlines: the
  arithmetics, `apply', the caddr family, etc. This makes the benchmarks
  *much* faster.

* module/language/scheme/translate.scm (trans): Remove the
  %scheme-primitives code in favor of the generic (scheme il inline)
  code. Adds inlining for +, -, =, etc.

* src/vm.c (vm_puts): Fix to work.

* module/system/base/compile.scm (system): Export load/compile also.

* module/system/il/compile.scm (optimize): Further debitrotting, but I
  haven't tried this function yet. It seems that <ghil-inst> was what
  <ghil-inline> is.

* module/system/il/ghil.scm (*core-primitives*, *macro-module*)
  (ghil-primitive-macro?, ghil-macro-expander, ghil-primitive?): Remove
  these unused things.

* module/system/il/macros.scm: Removed, replaced with inline.scm.

* module/system/vm/assemble.scm (stack->bytes): Before, the final
  serialization code did an (apply u8vector (apply append (map
  u8vector->list ...))). Aside from the misspelling of append-map, this
  ends up pushing all elements of the u8vector on the stack -- assuredly
  not what you want. But besides even that, I think that pushing more
  than 32k arguments on the stack brings out some other bug that I think
  was hidden before, because now we actually use the `apply' VM
  instruction. Further testing is needed here, I think. Fixed the code to
  be more efficient, which fixes the manifestation of this particular
  bug: a failure to self-compile after inlining was enabled.

* module/system/vm/bootstrap.scm: New module, serves to bootstrap
  boot-9's `load-compiled'. That way when we load (system vm core), we're
  loading compiled code already.

* module/system/vm/core.scm: Use (system vm bootstrap).

* src/guilec.in: Use the bootstrap code, so that we really are compiling
  with an entirely compiled compiler.

* module/system/repl/repl.scm (default-catch-handler): An attempt at
  making the repl print a backtrace; more work needed here.

* module/system/vm/frame.scm (make-frame-chain): Fix some misspellings --
  I think, anyway.

* module/system/il/Makefile.am:
* module/system/repl/Makefile.am:
* module/system/vm/Makefile.am: Use guilec.mk.

* module/system/base/compile.scm (compiled-file-name): Work on the
  basename of a file, so that we always create files in the directory
  where we run. Perhaps should add a -o option to guilec in the future.

* Makefile.am: Actually recurse into module/ in a normal build.

292bb8fc68 include local copy of guile.m4
* acinclude.m4: Add guile.m4 to this, because I really can't be arsed
  with aclocal.

1f246cb782 autotooling, version bump to 0.7
* acconfig.h: Removed.

* acinclude.m4: Use the extended AC_DEFINE for HAVE_LABELS_AS_VALUES, so
  as to remove the need for acconfig.h.

* autogen.sh: Use autoreconf.

* configure.in: Update info, don't warn about non-gnu make, bump version
  to 0.7.

* doc/texinfo.tex: Automagically updated. (Should this be in VCS?)

b571a648d5 fix distcheck
* src/Makefile.am (AM_CFLAGS, libguile_vm_la_LDFLAGS): Don't build with
  -pg. (There are better profilers out there.)
  (CLEANFILES): Add guilev and guile-disasm.

* testsuite/Makefile.am (GUILE_VM): s/srcdir/builddir/.
2008-05-20 11:54:05 +02:00

13c4775352 properly include config.h in source files, not headers
* src/Makefile.am: Add $(DEFAULT_INCLUDES) to a couple of our custom
  rules so we pick up the -I for config.h.

* src/*.[ch]: Include the config.h in the C files, not in the headers.

d79d908ef0 guile-vm is completely self-compiling now!
* module/language/scheme/translate.scm (*the-compile-toplevel-symbol*):
  Reset to compile-toplevel, which requires a patch to guile.

* module/system/base/compile.scm (compile-file): Some foo so that we load
  up the scheme language before call-with-output-file. Fixes compilation
  of (language scheme) modules.

* module/system/base/language.scm (define-language): Don't unquote in
  make-language; refer to it by name instead, and export it.

* module/system/repl/Makefile.am (vm_DATA): Don't compile describe.scm,
  because we really can't deal with goops yet.

* module/system/repl/repl.scm (compile-toplevel): If we're compiling, put
  in a stub definition of start-stack, which is closely tied to the
  interpreter.

* src/vm_loader.c (load-program): Fix a very tricky corruption bug!
2008-05-20 11:33:28 +02:00
Andy Wingo
5163e95138 fix syntax error in describe.scm
* module/system/repl/describe.scm (format-documentation): Remove bad
  string syntax. This file doesn't compile though, due to define-macro
  being a procedure->syntax macro.

Andy Wingo
9246a48606 fix immediate linkage, some other fixes to allow vm/ to compile
* module/language/scheme/translate.scm (lookup-transformer): Allow for
  undefined variables when doing the transformation -- it's possible that
  they come from a module definition's forward declaration.

* module/system/repl/command.scm (import): Make into legal Scheme, caught
  by the compiler :-)

* module/system/vm/assemble.scm (<vlink-now>): Remove the module field.
  Immediate bindings will now always be relative to the current module.
  Fixes some mess about process-define-module not being defined when
  loading modules, probably because we destructively modified the
  ghil-env.
  (codegen, dump-object!): Don't dump a module name.

* src/vm_loader.c (link-now): Just use scm_lookup.

6297d22907 bind all module-level variables lazily
comments in ghil-lookup are pertinent.

* module/system/il/compile.scm (make-glil-var): Require that ghil vars
  have environments. Remove the 'unresolved case -- we'll treat all
  module-level variables as late bound.

* module/system/il/ghil.scm (ghil-lookup): Treat all module level vars as
  late bound.

* module/system/vm/assemble.scm: Instead of vlink and vlate-bound, have
  vlink-now and vlink-later.
  (codegen): Add a bunch of crap to get the various cases right.
  (object-assoc, dump-object!): Handle the new cases, remove the old
  cases.

* src/vm_loader.c (link-now, link-later): Change from link and lazy-bind.
  Include the module in which the link is to be done, so that callers
  from other modules get the right behavior.

* src/vm_system.c (late-variable-ref, late-variable-set): Instead of a
  sym, the unbound representation is a module name / symbol pair.

* testsuite/run-vm-tests.scm (run-vm-tests): Remove some debugging.

9cc649b880 Add instructions for doing very late binding
Fixes the mutually-recursive toplevel definitions case. This could be
fixed by rewriting bodies as letrecs, as r6 does, but that's not really
repl-compatible.

* module/system/il/ghil.scm (ghil-lookup): Ok, if we can't locate a
  variable, mark it as unresolved.

* module/system/il/compile.scm (make-glil-var): Compile unresolved
  variables as <glil-late-bound> objects.

* module/system/il/glil.scm: Add <glil-late-bound> definition.

* module/system/vm/assemble.scm (codegen): And, finally, when we see a
  <vlate-bound> object, allocate a slot for it in the object vector,
  setting it to a symbol. Add a new pair of instructions to resolve that
  symbol to a variable at the last minute.

* src/vm_loader.c (load-number): Bugfix: the radix argument should be
  SCM_UNDEFINED in order to default to 10.
  (late-bind): Add an unresolved symbol to the object vector. Could be
  replaced with load-symbol I guess.

* src/vm_system.c (late-variable-ref, late-variable-set): New
  instructions to do late symbol binding.

* testsuite/Makefile.am (vm_test_files):
* testsuite/t-mutual-toplevel-defines.scm: New test, failing for some
  reason involving the core even? and odd? definitions.

1b8abe5514 compile all of base/; some arbitrary changes; more "fixes" to `link'
* module/language/scheme/translate.scm (lookup-transformer): When
  expanding syncase macros, use the eval closure from the ghil-env.
  Probably doesn't make any difference whatsoever.

* module/system/base/Makefile.am (SOURCES): Compile pmatch.scm, now that
  it works :-))

* module/system/base/compile.scm (compile-in): Compile inside a
  save-module-excursion, so that side effects of evaluation don't leak
  out.

* module/system/base/pmatch.scm: Change from :use-syntax/:export-syntax
  to simply :use-modules/:export. Also probably has no effect.

* module/system/il/ghil.scm (fix-ghil-mod!): Suppress warnings resulting
  from compilation of define-module.

* src/vm_loader.c (link): So, referencing variables defined but not
  exported from the current module didn't work. Fixed that, but it's
  hacky. There are still some uncaught cases.

8f43eb2b42 syncase macros compiling!
* module/system/base/compile.scm: Also import load-objcode from (system
  vm core).

* module/language/scheme/translate.scm (lookup-transformer): Use
  sc-expand3 in compilation mode when compiling macros. Yay, syncase
  macros compile!
2008-05-19 10:38:18 +02:00
Andy Wingo
a52b96a70a rudimentary syncase support; some dash symbol syncase removal
* module/system/vm/assemble.scm (dump-object!):
* src/vm_loader.c (VM_DEFINE_LOADER): Use scm_from_locale_keywordn, not
  the krazy dash symbol stuff.

* module/language/scheme/translate.scm (lookup-transformer): Add a
  special case for syncase macros.

7f52f9e3b4 avoid zealous unquotation
* module/system/base/syntax.scm (define-record): Again, don't unquote in
  actual objects, because this is uncompilable. Ah well. At least now all
  of base/ is compiling.

* module/system/vm/assemble.scm (dump-object!): More debug info.

cd702346f2 fix else in cond, letrec env corruption, syntax.scm compile, define-module side effects
* module/language/scheme/translate.scm (primitive-syntax-table):
  Translate the `else' clause of a cond as (begin ...). We used to use
  trans-body, which processes internal defines, which are not legal
  syntax here.

* module/system/base/syntax.scm (define-record): Unfortunately, we can't
  unquote in the actual procedure for `%compute-initargs', because that
  doesn't work with compilation. So reference %compute-initargs by name,
  and export it.

* module/system/il/ghil.scm (apopq!): Gaaaaar. The order of the arguments
  to assq-remove! was reversed, which was the badness, causing corruption
  to the env after calling call-with-ghil-bindings. Grrrrrr.

  (fix-ghil-mod!, ghil-lookup, ghil-define): As amply commented in the
  code, deal with compile-time side effects to the current module by
  lazily noticing and patching up the compile-time environment. A hacky
  solution until such a time as we special-case something for
  `define-module'.

6167de4f72 `link' instruction links to symbols by module
* module/system/il/compile.scm (make-glil-var): Only dump the module if
  we actually have one.

* module/system/il/ghil.scm (ghil-define): Make sure that ghil-var-env is
  a ghil-env.

* src/vm_loader.c (link):
* module/system/vm/assemble.scm (dump-object!): Rewrite `link' to take
  two Scheme arguments on the stack: the symbol, as before, and the
  module in which the symbol was found at compile time. This introduces
  some undesireable early binding, but it does let the vm load up
  modules, and (potentially) have multiple modules in one .go file. On a
  practical level, I can now compile modules and have their .go files
  load up the modules' dependencies as necessary.

Andy Wingo
5e1cead419 push the module resolution info for variables down into glil
* module/system/il/compile.scm (make-glil-var): Make the :mod of the
  glil-var actually a guile module, not a ghil-env.

* module/system/il/ghil.scm (module-lookup, ghil-lookup): For module
  variables, encode the location where we found the variable in the
  ghil-var.

10be70254b fix dumping of #:keywords
* module/language/scheme/translate.scm (trans):
* module/system/il/compile.scm (codegen): When making records where a
  value can be a keyword, make sure to use the keyword initialization
  form, so that the record initializer doesn't interpret the keyword as a
  slot name.

* module/system/base/Makefile.am (vm_DATA): For now, don't compile
  pmatch.
2008-05-15 12:20:18 +02:00

bd76c6d3ea allow interpretation of load-toplevel as compile-toplevel
* module/language/scheme/translate.scm (*the-compile-toplevel-symbol*)
  (primitive-syntax-table): Existing eval-case invocations in boot-9.scm
  only have `load-toplevel', not `load-toplevel' and `compile-toplevel'
  as they should. Allow for interpreting `load-toplevel' as
  `compile-toplevel'.
2008-05-15 11:17:00 +02:00

e009240547 rework eval-case handling to be like cl's eval-when
* module/language/scheme/translate.scm (trans): Remove the hacky case for
  the unspecified value, not needed any more.
  (primitive-syntax-table): Rework eval-case to understand
  compile-toplevel and evaluate contexts, as in common lisp's eval-when:
  http://www.lisp.org/HyperSpec/Body/speope_eval-when.html
  This is the Right Thing.

0658041d11 fix use-syntax / use-modules confusion -- fixes testsuites
* testsuite/t-match.scm:
* testsuite/t-records.scm: While the attempt to redefine use-syntax as
  being "use during compilation" was cute, it does not reflect the
  historical usage of use-syntax, nor does it correspond to existing code
  that includes other modules and uses them during compilation.

  So use-syntax has been replaced with use-modules. The test suites now
  pass. In the future, compilation phases should be done on whole
  modules, I think; r5rs-style computation does not have phases.

7d1c45d38e fix macro compilation via hooking into eval-case
* module/language/scheme/translate.scm (eval-at-compile-time)
  (&compile-time-module, expand-macro): Remove this attempt at dealing
  with macros. Instead, we're going to rely on macros being first-class,
  and just catch eval-case at the bottom.
  (lookup-transformer): Lookup all syntax transformers in the module's
  eval closure. We catch the primitive-macros, compiling them to ghil,
  and expand the rest.
  (lookup-transformer): Fold in trans-pair here. Add a hacky case for the
  unspecified value; the problem shows up when compiling e.g.
  (define-macro (plus! x) `(set! ,x (1+ x))), as a fallout from
  eval-case.
  (make-pmatch-transformers, primitive-syntax-table): Define the
  primitive syntax transformers as a data-driven table instead of a
  function. There's a bit of syntax, too. Eval-case was rewritten to use
  pmatch.

* module/system/base/compile.scm (scheme): Define as a thunk instead
  of a value, so as to allow (language scheme translate) to be imported
  in the repl. Still, a hack.
2008-05-14 14:47:29 +02:00
Andy Wingo
c78279fc40 (void) -> (begin)
* module/language/scheme/translate.scm (expand-macro, trans-pair): Remove

  Keisuke thinking? :)

* module/system/repl/repl.scm (default-pre-unwind-handler)

db917b4152 replace cenv with things in <repl> and fluids; remove the `use' meta-command
* module/system/base/compile.scm (<cenv>): No more cenv, it was a useless
  data structure.

* module/system/repl/command.scm (*command-table*): Remove `use', it's
  the same as `import'. Otherwise in this file, adapt to the repl having
  direct pointers to the vm and the language, and to the module being in
  the current-module fluid.

* module/system/repl/repl.scm (prompting-meta-read):
* module/system/repl/common.scm (<repl>): The repl now has a direct
  pointer to the vm and language. Adapt accordingly.

cd9d95d760 fixes so that typing asdfadfasff in the repl doesn't error
Before:

> ,c (set! x 3)
   0    (make-int8 3)                   ;; 3
   2    (link "x")
   5    (variable-set)

> ,c (define x 3)
   0    (make-int8 3)                   ;; 3
   2    (link "x")
   5    (variable-set)

After:
> ,c (define x 3)
   0    (make-int8 3)                   ;; 3
   2    (define "x")
   5    (variable-set)

* src/vm_loader.c (link): `link' now errors if the variable is undefined.
  This corresponds with desired behavior, for both `ref' and `set'
  operations, for scheme. It's not what elisp wants, though. Perhaps
  elisp linking needs another instruction.
  (define): New instruction, the same as calling scm_define(), basically.

* module/language/scheme/translate.scm (trans-pair): Don't try to look up
  an existing variable definition when translating `define'; instead use
  the special-purpose lookup from ghil.scm's `ghil-define'.

* module/system/il/compile.scm (codegen): Compile to a different kind of
  variable access from `set!', specifically via passing 'define as the op
  to `make-glil-var'.

* module/system/il/ghil.scm (ghil-lookup): Don't add to the module table
  when compiling variable sets via `set!'.
  (ghil-define): New procedure, for looking up variables for `define'.

* module/system/vm/assemble.scm (<vdefine>): New record: a new
  instruction type.
  (codegen): Compile `define' module vars into <vdefine>.
  (dump-object!): <vdefine> == `define'.

f540e3271b Replace ice-9 match's structures with guile's records
* module/system/base/syntax.scm (define-record): Rebase to implement on
  top of Guile's records, which are the substrate of srfi-9's records.
  (%compute-initargs): Rename from %make-struct, just return the list of
  values.
  (get-slot, set-slot!, slot): Removed, no longer used.
  (record-case): Allow slots of the form (MYNAME SLOTNAME), which binds
  SLOTNAME to MYNAME (instead of SLOTNAME to SLOTNAME).
  (record-case, record?): No more ice-9 match!

* module/system/il/compile.scm (codegen): Tweaks so that the new record
  code works.

* module/system/il/ghil.scm: Fix some slot references.

* module/system/vm/assemble.scm (preprocess, codegen): Remove calls to
  `slot'.
  (codegen): Fix some slot references.
