eb1482ac46 debitrot the ecmascript compiler
* module/Makefile.am (ECMASCRIPT_LANG_SOURCES):
* module/language/ecmascript/compile-ghil.scm:
* module/language/ecmascript/compile-tree-il.scm: SOURCES): Replace the
  GHIL compiler with a ->tree-il compiler. Not fully functional, but the
  basics work.

* module/language/ecmascript/spec.scm: Only include the tree-il compiler.

* module/language/ecmascript/tokenize.scm (read-punctuation): Avoid
  mutating a constant.

8f9b968329 some attempts to solve the ecmascript stack overflow problem
* module/language/ecmascript/compile-ghil.scm (comp): Just use pmatch,
  not ormatch. Now with syncase running over everything, it doesn't
  matter.

* module/ice-9/boot-9.scm (false-if-exception): Avoid saving stacks
  inside false-if-exception. There's probably a more general solution to
  this, though. Fixes getting bogus backtraces sometimes.

* module/Makefile.am (ECMASCRIPT_LANG_SOURCES): Reorder things so that
  spec comes last.

81fd315299 update docs, clean up VM vestiges, macro docs, fix (/ a b c)
* doc/ref/api-procedures.texi (Compiled Procedures): Fix for API changes.

* doc/ref/compiler.texi (Compiling to the Virtual Machine): Replace GHIL
  docs with Tree-IL docs. Update the bits about the Scheme compiler to
  talk about Tree-IL and the expander instead of GHIL. Remove
  <glil-argument>. Add placeholder sections for assembly and bytecode.

* doc/ref/vm.texi: Update examples with what currently happens. Reword
  some things. Fix a couple errors.

* libguile/vm-i-system.c (externals): Remove this instruction, it's not
  used.

* module/ice-9/documentation.scm (object-documentation): If the object is
  a macro, try to return documentation on the macro transformer.

* module/language/assembly/disassemble.scm (disassemble-load-program):
  Fix problem in which we skipped the first element of the object vector,
  because of changes to procedure layouts a few months ago.

* module/language/scheme/spec.scm (read-file): Remove read-file
  definition.

* module/language/tree-il.scm: Reorder exports. Remove <lexical>, it was
  a compat shim to something that was never released. Fix `location'.

* module/language/tree-il/primitives.scm (/): Fix expander for more than
  two args to /.

* module/system/base/compile.scm (read-file-in): Remove unused
  definition.

* module/system/base/language.scm (system): Remove language-read-file.

b41b92c9d1 compilation passes return third value: the continuation environment
* module/system/base/compile.scm: Expect compile passes to produce three
  values, not two. The third is the "continuation environment", the
  environment that can be used to compile a subsequent expression from
  the same source language. For example, expansion-time side effects can
  set the current module, which would be reflected appropriately in the
  continuation environment.

* module/language/assembly/compile-bytecode.scm:
* module/language/bytecode/spec.scm:

* module/language/objcode/spec.scm:
* module/language/scheme/compile-ghil.scm:
* module/system/base/compile.scm: Update compile passes to return a
  continuation environment.

* module/language/ecmascript/compile-ghil.scm: Use -> to make the ES
  compiler more readable. Fix bugs in do, while, and for, whereby we were
  missing ->boolean calls.

e05320fa54 compile for-in
* module/language/ecmascript/base.scm (prop-keys): New method, returns
  the list of keys of props of this instance.

* module/language/ecmascript/impl.scm: Refactor the global object into a
  special kind of module object. Provide a prop-keys implementation for
  module objects.

143177ed9e add scheme integration to js via `require'
* module/language/ecmascript/impl.scm: Add <js-module-object>, that wraps
  a module. Add js-require, a javascript-happy function that returns an
  object that wraps a Guile module. Bind it to `require' in the default
  environment.

a3e34104db ecmascript tokens have source info
* module/language/ecmascript/tokenize.scm: Attach source information to
  tokens. We have to enhance the lalr parser to actually let this
  information propagate through, though...

8c306808c2 + for strings, global js object, new Foo() works
* module/language/ecmascript/array.scm (*array-prototype*): Declare the
  constructor.

* module/language/ecmascript/base.scm (pput, pdel): Remove some needless
  checks.
  (new): Move definition of new here, and use the constructor.

* module/language/ecmascript/compile-ghil.scm (compile-ghil): Add a stub
  so that when we load a compiled JS program, we make sure the runtime
  has been booted.

* module/language/ecmascript/function.scm (js-constructor): Export a
  js-constructor method instead of a new method.

* module/language/ecmascript/impl.scm (<js-global-object>): Define a new
  class for the global "this" object, wrapping bindings from the current
  module.
  (init-js-bindings!): Define the dozen or so global properties, in the
  current module.
  (+): Define addition operations for non-numbers. This is efficient
  because the generics are only dispatched if the fast-path fails.

aec8febc46 compile ecmascript's parser. yay! instant load-time!
* module/language/ghil/compile-glil.scm (codegen): If there are more than
  255 arguments, make a list and use apply instead of calling directly.

* module/language/Makefile.am: Now we can compile parse.scm. Yay!

* module/language/scheme/compile-ghil.scm: Add a note.

594d9d4c48 be smarter about allocating local variables, reusing slots if possible
* module/language/Makefile.am: OK, we can compile compile-ghil.scm now,
  thankfully.

* module/language/ecmascript/compile-ghil.scm (ormatch): New macro, a
  wrapper around pmatch to avoid some of the more egregious
  non-tail recursiveness.
  (comp): Use ormatch.

* module/language/ghil.scm (unparse-ghil): The body of bind and mv-bind
  is a single expression, not a list of expressions.

* module/language/ghil/compile-glil.scm (codegen): Be more clever when
  allocating "local" variables -- if a variable goes out of scope, its
  index can be re-used later.

* module/language/glil.scm (parse-glil, unparse-ghil): The "rest" of a
  mv-bind is a flag, not a list. The "ra" of an mv-call is a label, not a
  GLIL expression.

* module/language/objcode/spec.scm (collapse-locals, decompile-value):
  When decompiling a value, process the bindings list differently.
  Comments in the code.

* module/language/scheme/compile-ghil.scm (define-scheme-translator): Fix
  the generated error procedure.
  (let): Re-indent.
  (letrec): Re-indent.

* module/system/base/syntax.scm (record-case): If the body of a clause is
  null, fill it with the unspecified value.

81d677eb12 implement break and continue, work around overly recursive pmatch expansion
* libguile/vm-i-system.c (goto/args): On a tail call to a different
  procedure, init the locals to valid scheme values. Shouldn't matter for
  well-compiled scheme, but inspecting uninitialized locals could give
  garbage, or badly-compiled code could cause a crash.

* module/language/Makefile.am (NOCOMP_SOURCES): For the moment, don't
  compile compile-ghil.scm. I need to fix this.

* module/language/ecmascript/compile-ghil.scm (load-toplevel): Sigh, and
  disable stack checking in the evaluator too. Grr.
  (comp): Implement (unnamed) break and continue.

* module/language/ecmascript/parse.scm (parse-ecmascript): Fix var
  statements in `for' -- though it still doesn't work.

Andy Wingo
3bef3ae428 implement do, while, for
* module/language/ecmascript/compile-ghil.scm (comp): Use ghil-bind when
  making temp vars, so that disassembly understands things. Implement do,
  while, and for.

* module/language/ecmascript/parse.scm (parse-ecmascript): Some tweaks.

* module/language/ecmascript/impl.scm (language): Export ->boolean.

b358fe6502 implement more operations
* module/language/ecmascript/base.scm: Implement some more robust
  property getters that convert strings to symbols. Implement
  has-property?.

* module/language/ecmascript/compile-ghil.scm (comp): Implement lots more
  mathematical operators. We now do all expressions; on to statements.

* module/language/ecmascript/impl.scm: Define some math helpers. They
  probably need to call ->number on some things.

* module/language/ecmascript/parse.scm (parse-ecmascript): Fix a typo.

a287987818 implement ++, --, new, delete, void, typeof
* module/language/ecmascript/compile-ghil.scm (@impl): Implement with
  @implv.
  (comp): Implement ++ and -- (pre- and post-). Quite a pain. I'll be
  looking for ways to simplify this notation. Also implement new, delete,
  and void.

* module/language/ecmascript/impl.scm: Implement typeof.

cdad2166e7 support foo["bar"] in addition to foo.bar
* module/language/ecmascript/parse.scm (parse-ecmascript): And update the
  function declaration forms for the new var syntax.

* module/language/ecmascript/compile-ghil.scm (comp): Support foo["bar"]
  in addition to foo.bar.

* module/language/ecmascript/impl.scm (pget, pput): Some fixes for when
  we get non-symbols -- it can happen, yo. I suppose we should allow for
  non-string keys too..

* module/language/ecmascript/compile-ghil.scm (@impl): Ok, don't recurse
  on args here.

  (comp-body): Fix scanning of var forms.

* module/language/ecmascript/impl.scm (prop-attrs): Allow for the prop
  attr array to be #f.

131f7d6c71 further ecmascript work
* libguile/vm-i-system.c (drop, return): Declare drop and return as
  popping one arg from the stack.

* module/language/ghil/compile-glil.scm:
* module/language/glil/compile-assembly.scm (make-meta): Adjust so that
  we declare 'drop and 'return calls as popping one arg from the stack.

* module/language/ecmascript/compile-ghil.scm (comp, comp-body): Flesh
  out a bit more. Most significantly, scoping within functions obeys
  javascript semantics better, modulo bits about with() forms.

* module/language/ecmascript/impl.scm: Define some runtime helper
  routines.
* module/language/Makefile.am (SOURCES): Add impl.scm.

* module/language/ecmascript/parse.scm (parse-ecmascript): Minor tweaks.

  compilers.

5dcd3e4801 add ecmascript parser
* module/language/ecmascript/parse-lalr.scm: Add the Boucher/Bison lalr
  parser. This is from guile-lib, but with : changed to -> so as not to
  molest `prefix' keywords. Should probably be elsewhere.

* module/language/ecmascript/parse.scm: Add parser for ECMAScript. Rules
  from the spec, 3rd edition.

* module/language/ecmascript/tokenize.scm: Add ECMAScript tokenizer,
  hand-written. Neat stuff.
