5161a3c0d7 add new scheme evaluator
* module/ice-9/eval.scm: New evaluator, written in Scheme. Whee!
  Batteries included but not wired up.

* module/Makefile.am: Abuse touch(1) to make sure eval.go gets built
  before everything. Can't just depend on eval.go, because eval.go will
  get the timestamp of eval.scm, which might be newer than foo.go (and
  thus foo.scm). Something better is warranted.

b7742c6b71 new evaluator, y'all
* libguile/eval.c: So, ladies & gents, a new evaluator. It's similar to
  the old one, in that we memoize and then evaluate, but in this
  incarnation, memoization of an expression happens before evaluation,
  not lazily as the expression is evaluated. This makes the evaluation
  itself much cleaner, in addition to being threadsafe. In addition,
  since this C evaluator will in the future just serve to bootstrap the
  Scheme evaluator, we don't have to pay much concern for debugging
  conveniences. So the environment is just a list of values, and the
  memoizer pre-computes where it's going to find each individual value
  in the environment.

  Interface changes are commented below, with eval.h.

  (scm_evaluator_traps): No need to reset the debug mode after rnning te
  traps thing. But really, the whole traps system needs some love.

* libguile/memoize.h:
* libguile/memoize.c: New memoizer, which runs before evaluation,
  checking all syntax before evaluation begins. Significantly, no
  debugging information is left for lexical variables, which is not so
  great for interactive debugging; perhaps we should change this to have
  a var list in the future as per the classic interpreters. But it's
  quite fast, and the resulting code is quite good. Also note that it
  doesn't produce ilocs, memoized code is a smob whose type is in the
  first word of the smob itself.

* libguile/eval.h (scm_sym_and, scm_sym_begin, scm_sym_case)
  (scm_sym_cond, scm_sym_define, scm_sym_do, scm_sym_if, scm_sym_lambda)
  (scm_sym_let, scm_sym_letstar, scm_sym_letrec, scm_sym_quote)
  (scm_sym_quasiquote, scm_sym_unquote, scm_sym_uq_splicing, scm_sym_at)
  (scm_sym_atat, scm_sym_atapply, scm_sym_atcall_cc)
  (scm_sym_at_call_with_values, scm_sym_delay, scm_sym_eval_when)
  (scm_sym_arrow, scm_sym_else, scm_sym_apply, scm_sym_set_x)
  (scm_sym_args): Remove public declaration of these symbols.
  (scm_ilookup, scm_lookupcar, scm_eval_car, scm_eval_body)
  (scm_eval_args, scm_i_eval_x, scm_i_eval): Remove public declaration
  of these functions.
  (scm_ceval, scm_deval, scm_ceval_ptr): Remove declarations of these
  deprecated functions.
  (scm_i_print_iloc, scm_i_print_isym, scm_i_unmemocopy_expr)
  (scm_i_unmemocopy_body): Remove declarations of these internal
  functions.
  (scm_primitive_eval_x, scm_eval_x): Redefine as macros for their less
  destructive siblings.

* libguile/Makefile.am: Add memoize.[ch] to the build.

* libguile/debug.h (scm_debug_mode_p, scm_check_entry_p)
  (scm_check_apply_p, scm_check_exit_p, scm_check_memoize_p)
  (scm_debug_eframe_size): Remove these vars that were tied to the old
  evaluator's execution model.
  (SCM_RESET_DEBUG_MODE): Remove, no more need for this.
  (SCM_MEMOIZEDP, SCM_MEMOIZED_EXP, SCM_MEMOIZED_ENV): Remove macros
  referring to old memoized code representation.
  (scm_local_eval, scm_procedure_environment, scm_memoized_environment)
  (scm_make_memoized, scm_memoized_p): Remove functions operating on old
  memoized code representation.
  (scm_memcons, scm_mem_to_proc, scm_proc_to_mem): Remove debug-only
  code for old evaluator.

* libguile/debug.c: Remove code to correspond with debug.h removals.
  (scm_debug_options): No need to set the debug mode or frame limit
  here, as we don't have C stack limits any more. Perhaps this is a bug,
  but as long as we can compile eval.scm, we should be fine.

* libguile/init.c (scm_i_init_guile): Init memoize.c.

* libguile/modules.c (scm_top_level_env, scm_env_top_level)
  (scm_env_module, scm_system_module_env_p): Remove these functions.

* libguile/print.c (iprin1): No more need to handle isyms. Adapt to new
  form of interpreted procedures.

* libguile/procprop.c (scm_i_procedure_arity): Adapt to new form of
  interpreted procedures.

* libguile/procs.c (scm_thunk_p): Adapt to new form of interpreted
  procedures.
* libguile/procs.h (SCM_CLOSURE_FORMALS): Removed, this exists no more.
  (SCM_CLOSURE_NUM_REQUIRED_ARGS, SCM_CLOSURE_HAS_REST_ARGS): New
  accessors.

* libguile/srcprop.c (scm_source_properties, scm_source_property)
  (scm_set_source_property_x): Remove special cases for memoized code.

* libguile/stacks.c (read_frame): Remove a source-property case for
  interpreted code.
  (NEXT_FRAME): Remove a case that I don't fully understand, that seems
  to be designed to skip over apply frames. Will be obsolete in the
  futures.
  (read_frames): Default source value for interpreted frames to #f.
  (narrow_stack): Don't pay attention to the system_module thing.

* libguile/tags.h: Remove isyms and ilocs. Whee!

* libguile/validate.h (SCM_VALIDATE_MEMOIZED): Fix to use the new
  MEMOIZED_P formulation.

* module/ice-9/psyntax-pp.scm (do, quasiquote, case): Adapt for these no
  longer being primitive macros.
* module/ice-9/boot-9.scm: Whitespace change, but just a poke to force a
  rebuild due to and/or/cond/... not being primitives any more.

* module/ice-9/deprecated.scm (unmemoize-expr): Deprecate, it's
  unmemoize-expression now.

* test-suite/tests/eval.test ("define set procedure-name"): XFAIL a
  couple of tests here; I don't know what to do about them. I reckon the
  expander should ensure that defined values are named.

* test-suite/tests/chars.test ("basic char handling"): Fix expected
  exception when trying to apply a char.

ff74e44ecb with a rest arg, allow for keywords anywhere
* libguile/vm-i-system.c (br-if-nargs-gt): Fix variable declaration
  placement.
  (bind-kwargs): Patch mostly by Ludovic: it seems that in the mode in
  which we have rest args, the keywords can appear anywhere. Bummer.
  Change to allow for this.

* module/ice-9/optargs.scm (parse-lambda-case): Same, add a
  permissive-keys clause that handles the case in which there's a rest
  argument.

1e2a8edb8b Revert "implement #:predicate" and remove predicate from <lambda-case>
Turns out this was not a very useful idea, and semantically tricky to
boot.

This reverts commit 24bf130fd1, and makes
the following additional changes:

* module/ice-9/optargs.scm (parse-lambda-case, let-optional)

  (unparse-tree-il, tree-il->scheme, tree-il-fold,
  make-tree-il-folder)

  #:predicate from tree-il.

* module/ice-9/psyntax.scm (build-simple-lambda, build-lambda-case)
  (chi-lambda-case): Adapt to tree-il change.
* module/ice-9/psyntax-pp.scm: Regenerated.

* module/ice-9/optargs.scm (let-keywords): I thought that I had the
  scoping right here, but I didn't. Make sure that the lambda formals
  for the initializers are new, fresh identifiers, so that let scoping
  works appropriately.

24bf130fd1 implement #:predicate
will be useful for making e.g. typecase-lambda. Tough to tell though.

* module/ice-9/psyntax.scm (lambda-formals, lambda*-formals): Parse out
  a #:predicate, which goes right before the rest args. The vanilla
  lambda doesn't parse it out of course, but it does return another
  value.
  (chi-lambda-case, lambda*, lambda): Expand and pass the predicate on
  to build-lambda-case.

* module/ice-9/psyntax-pp.scm: Regenerate.

* module/language/tree-il/compile-glil.scm (flatten): Compile a failing
  predicate without an else clause into a call to `error'. Also, fix
  something the compile warnings caught.

  logic is in one place.
  (lambda*): Re-export from the default environment -- it's all in the
  VM now :-))

  Also work around a nasty memoizer bug: see
  http://article.gmane.org/gmane.lisp.guile.devel/9561.
  (lambda*): Implement in psyntax, in the default environment. Exciting
  stuff!

b0c8c187d9 separate "inits" field in <lambda-case>; compile fixes for inits, kwargs
* module/language/tree-il.scm (<lambda-case>): Add "inits" field, so we
  don't have to parse it out of opt and kw. Adapt the traversal
  procedures.
* module/language/tree-il/analyze.scm (analyze-lexicals): Analyze
  lexicals in the <lambda-case> init expressions as well. Fix keyword
  allocation.

* module/language/tree-il/compile-glil.scm (compile-glil): Adapt to
  make-lambda-case change.
  (flatten): Adapt to "inits" slot, actually init uninitialized args,
  and fix bugs related to keyword arguments.

* module/language/tree-il/inline.scm (inline!): Adapt a little bit --
  but with no effect.

* module/language/glil/compile-assembly.scm (glil->assembly): Flesh out
  <glil-kw-prelude> compilation some more. Add a "bound?" op for
  <glil-lexical>, which will push #t if the local is bound.

* module/ice-9/psyntax.scm (build-simple-lambda, build-lambda-case):
  Update for new signature of make-lambda-case.
* module/ice-9/psyntax-pp.scm: Regenerated.

* module/language/brainfuck/compile-tree-il.scm (compile-body):
* module/language/ecmascript/compile-tree-il.scm (comp):
* test-suite/tests/tree-il.test ("lambda"): Update for new lambda-case
  syntax.

899d37a6cf more work towards compiling and interpreting keyword args
* libguile/_scm.h (SCM_OBJCODE_MINOR_VERSION): Bumparoo
* libguile/vm-i-system.c (push-rest, bind-rest): Logically there are
  actually two rest binders -- one that pops, conses, and pushes, and
  one that pops, conses, and local-sets. The latter is used on keyword
  arguments, because the keyword arguments themselves have been shuffled
  up on the stack. Renumber ops again.

* module/language/tree-il/compile-glil.scm (flatten): Attempt to handle
  compilation of lambda-case with keyword arguments. Might need some
  help.

* module/ice-9/psyntax.scm (build-lambda-case): An attempt to handle the
  interpreted case correctly. This might need a couple iterations, but
  at least it looks like the compile-glil code.

* module/ice-9/psyntax-pp.scm: Regenerated.

* module/language/glil.scm (<glil>): Rename "rest?" to "rest" in
  <glil-opt-prelude> and <glil-kw-prelude>, as it is no longer a simple
  boolean, but if true is an integer: the index of the local variable to
  which the rest should be bound.

* module/language/glil/compile-assembly.scm (glil->assembly): Adapt to
  "rest" vs "rest?". In the keyword case, use "bind-rest" instead of
  "push-rest".

* test-suite/tests/tree-il.test: Update for opt-prelude change.

8a4ca0ea3b tree-il support for case-lambda
* module/language/tree-il.scm (<lambda>, <lambda-case>): Split lambda
  into the lambda itself, denoting the procedure, and lambda-case,
  denoting a particular arity case. Lambda-case is fairly featureful,
  and has not yet been fully tested.
  (<let-values>): Use a <lambda-case> as the binding expression. Seems
  to suit the purpose well.
  Adapt parsers, unparsers, traversal operators, etc. Sometimes in this
  first version we assume there are no optional args, rest args, or a
  predicate.

* module/language/tree-il/analyze.scm (analyze-lexicals): Adapt for the
  new case-lambda regime. Fairly well commented. It actually simplifies
  things.
  (report-unused-variables): Update for new tree-il.

* module/language/tree-il/compile-glil.scm: Adapt for the new tree-il.
  There are some first stabs here at proper case-lambda compilation, but
  they are untested as of yet.

* module/language/tree-il/inline.scm (inline!): Rework so we can
  recurse on a single node; though these transformations are strictly
  reductive, so they should complete in bounded time. Simplify
  accordingly, and adapt to case-lambda. Oh, and we handle lambda->let
  in not just the nullary case.

* module/ice-9/psyntax.scm (build-simple-lambda, build-case-lambda)
  (build-lambda-case): New constructors. The idea is that after syntax
  expansion, we shouldn't have to deal with improper lists any more.
  Build-simple-lambda is a shortcut for the common case. The others are
  not fully exercised yet. Adapt callers.
  (syntax): Add some debugging in the lambda case. I don't fully
  understand this, but in practice we don't seem to see rest args here.
  (lambda): Inline chi-lambda-clause, and adapt for build-simple-lambda.
* module/ice-9/psyntax-pp.scm: Regenerated.

* test-suite/tests/tree-il.test: Update tests for new tree-il lambda
  format, and to expect post-prelude labels for all glil programs.

f95f82f8e1 compilation enviroments are always modules; simplifications & refactorings
* module/ice-9/boot-9.scm (make-fresh-user-module): New public function,
  makes an anonymous beautified module.

* module/language/objcode/spec.scm: We used to have some things in here
  that allowed lexical variable names and values to be a part of the
  environment, but no more. Now an environment is just a module. If you
  want to "inject" free variables into code, just use lambda.

* module/language/scheme/compile-tree-il.scm (compile-tree-il): Same
  here. Also, rely on the fact that an environment *will* be a module --
  because (system base compile) guarantees that for us.

* module/language/scheme/spec.scm (scheme): In the reader, rely on the
  environment being a module. Define a #:make-default-environment
  handler, which returns a beautified module, augmented with a fresh
  definition for current-reader, so that side effects to current-reader
  are restricted to the compilation unit.

* module/language/tree-il/analyze.scm
  (report-possibly-unbound-variables):
* module/language/tree-il/compile-glil.scm (compile-glil):
* module/language/tree-il/optimize.scm (optimize!): The environment will
  be a module.

* module/system/base/language.scm (<language>): New field,
  `make-default-environment'. Defaults to `make-fresh-user-module'.
  (default-environment): New accessor, returns a default environment for
  a language.

* module/system/repl/common.scm (repl-compile): Always compile relative
  to the current module, because a module is always acceptable as an
  environment.

* module/system/base/compile.scm (compile-file, compile-and-load): Both
  of these have a new keyword argument, #:env. For `compile-file', it
  defaults to the default environment of the source language, and for
  `compile-and-load', to the current module.
  (read-and-compile): If there are no expressions read, pass the joiner
  its default environment (via `default-environment joint').

* guile-readline/ice-9/readline.scm (activate-readline): Make our
  replacement definition of repl-reader compatible with boot-9.

  New test.

  Change mentions of (ice-9 debugging ice-9-debugger-extensions)
  module to whatever is appropriate now (or just remove them).

248ee86a0b Remove superfluous ice-9-debugger-extensions code for old Guile versions
* module/ice-9/debugging/ice-9-debugger-extensions.scm: Remove all
  code checking for version < 1.7, and move code for versions >= 1.7
  up to top level.  Comment out dummy mutex definitions for now, as
  I'm not sure how to rewrite them correctly for psyntax.

  primitive-eval.

9591a2b016 `load' autocompiles
* libguile/load.h:
* libguile/load.c (scm_sys_warn_autocompilation_enabled): New primitive,
  not exported. Since `load' autocompiles now, it should warn in the
  same way that the bits hardcoded into C warn.
  (scm_try_autocompile): Use scm_sys_warn_autocompilation_enabled.

* module/ice-9/boot-9.scm (autocompiled-file-name): New helper.
  (load): Try autocompiling the argument, if appropriate. Will
  autocompile files passed on Guile's command line. `primitive-load' is
  unaffected.
