811d10f5a2 new language: tree-il. psyntax generates it when run in compile mode.
* module/Makefile.am: Add tree-il sources.

* module/ice-9/compile-psyntax.scm: Adjust for sc-expand producing
  tree-il in compile mode.

* module/ice-9/psyntax.scm: Switch from expand-support to tree-il for
  generating output in compile mode. Completely generate tree-il -- the
  output wasn't Scheme before, but now it's completely not Scheme.

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

* module/language/scheme/compile-ghil.scm: Strip structures using
  tree-il, not expand-support.

* module/language/tree-il.scm:
* module/language/tree-il/spec.scm
* module/language/tree-il/compile-glil.scm: New language. It will compile
  to GLIL, though it doesn't yet.

71f46dbd5e sc-expand in compile mode produces (ice-9 expand-support) structures
* module/ice-9/psyntax.scm (*mode*): New moving part, a fluid.
  (sc-expand): Dynamically bind *mode* to the expansion mode.
  (build-global-reference): Change to be a procedure instead of local
  syntax. Import the logic about when to make a @ or @@ form to here,
  from boot-9.scm. If we are compiling, build output using (ice-9
  expand-support)'s make-module-ref, otherwise just making the familiar
  s-expressions. (This will allow us to correctly expand in modules in
  which @ or @@ are not bound, at least when we are compiling.)
  (build-global-assignment): Use the result of build-global-reference. A
  bit hacky, but hey.
  (top-level-eval-hook, local-eval-hook): Strip expansion structures
  before evalling.

* module/ice-9/boot-9.scm (make-module-ref): Remove, this logic is now
  back in psyntax.scm.

* module/ice-9/compile-psyntax.scm (source): Since we expand in compile
  mode, we need to strip expansion structures.

* module/ice-9/expand-support.scm (strip-expansion-structures): Remove
  the logic about whether and how to strip @/@@ from here, as it's part
  of psyntax now.

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

* module/language/scheme/compile-ghil.scm (compile-ghil): Strip expansion
  structures -- for now. In the future, we might translate directly from
  these structures into GHIL.

123f8abb2d replace sc-expand with sc-expand3, removing binding for sc-expand3
* module/ice-9/boot-9.scm (sc-expand3):
* module/ice-9/psyntax.scm (sc-expand3): Replace sc-expand with
  sc-expand3, as expand3 with one argument is the same as sc-expand.

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

* module/ice-9/compile-psyntax.scm:
* module/language/scheme/compile-ghil.scm: Change callers to sc-expand3
  to use sc-expand.

384e92b3ae fix @ and syncase
* module/ice-9/boot-9.scm
  (make-module-ref): equal?, not eq?, when matching on module name.
  (Module names don't have to come from an invocation of module-name in
  this process.)

* module/ice-9/psyntax.scm (build-global-reference)
  (build-global-assignment, @): Rework the format of the module in syntax
  objects so that a car of #f indicates a public reference. Loading (foo
  %module-public-interface) didn't guarantee that (foo) was loaded and
  useful.

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

* module/language/scheme/compile-ghil.scm (lookup-transformer):
  primitive-macro? does not exist any more.

01c161ca11 it is alive!!!!! + concision + fix to compile-ghil
* module/ice-9/boot-9.scm: Remove lots of debugging prints. Remove some
  already-deprecated attempts to load modules from shared libraries.

* module/ice-9/psyntax.scm: If we have to create a variable for a
  syntactic binding, initialize its contents to a gensym. I'd like
  something more meaningful, but at least this way we can tell different
  macros apart. Only warn about missing modules if modules are booted.
  Chi the value part of a (set! (@ ...) ) expression -- whoops!

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

* module/language/glil.scm (parse-glil): Fix an unquoting error.

* module/language/scheme/compile-ghil.scm: No need to import syncase, we
  gots it. Rework compiler to expand only once, with syncase, instead of
  incrementally. Fix define-scheme-transformer to work with syncase, by
  not referencing bare keywords. It works!

900761bc8d hygienic compilation
* module/language/scheme/compile-ghil.scm (lookup-transformer): Recognize
  macros as initial (@ ...) or (@@ ...) forms, enabling hygienic
  compilation.
2009-04-17 15:20:18 +02:00
Andy Wingo
8e1d0d507a more work on modules and hygiene, not finished yet, alas.
* module/ice-9/compile-psyntax.scm: No more expansion-eval-closure.

* module/ice-9/expand-support.scm (strip-expansion-structures): Only @@
  names whose module is not the current module. Actually @@ serialization
  is disabled for this commit, just to get this one in and keep things
  working.

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

* module/ice-9/psyntax.scm (put-global-definition-hook)
  (get-global-definition-hook): Instead of going through that stupid
  getprop/putprop interface, let's just inline Guile-specific code here.
  (build-global-reference, build-global-assignment): Fix a bug where the
  module and public? were switched, which happily allowed things to
  compile. (We reintroduce a similar bug above in expand-support.)
  (lookup): Add a module argument.
  (global-extend): Adapt for put-global-definition-hook invocation.
  (syntax-type): Lookup with mod. Return mod even for lexicals and
  define-form -- why not.
  (chi-top, fluid-let-syntax, syntax, set!): Lookup with mod. Wrap with
  mod.

* module/ice-9/syncase.scm (expansion-eval-closure)
  (current-eval-closure, env->eval-closure): OK! So the idea is: module
  hygiene is syncase's business, not ours. So lose the eval-closure
  fluid. Also, eval closures are so 1990s.
  (sc-macro): But, we have to take the module from the env, sadly. In the
  future this will be different.
  Remove the rest of the eval-closure bits. Enable source reporting,
  while we're debugging.

* module/language/scheme/compile-ghil.scm (lookup-transformer): Adapt for
  eval closure fluid changes.

9d80c15649 serialize module information into syncase's output -- getting ready for hygiene
* module/ice-9/Makefile.am: Replace annotate.scm with expand-support.scm.

* module/ice-9/annotate.scm: Removed; subsumed into expand-support.scm.

* module/ice-9/compile-psyntax.scm: Strip out expansion structures before
  writing to disk.

* module/ice-9/expand-support.scm: New file. Provides annotation support,
  and other compound data types for use by the expander. Currently the
  only one that is used is the toplevel reference, <module-ref>, but we
  will record lexicals this way soon.

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

* module/ice-9/psyntax.scm (build-global-reference)
  (build-global-assignment): Instead of expanding out global references
  as symbols, expand them as <module-ref> structures, with space to
  record the module that they should be scoped against. This is in
  anticipation of us actually threading the module info through the
  syntax transformation, so that we can get hygiene with respect to
  modules.

* module/ice-9/syncase.scm: Replace eval-when. Since sc-expand will give
  us something that isn't Scheme because we put the <module-ref>
  structures in it, strip that info whenever we actually do need scheme.

* module/language/scheme/compile-ghil.scm (lookup-transformer): Strip
  expansion structures here too.

* module/language/scheme/expand.scm (language): Swap annotate for
  expand-support. But this file will die soon, I think.

b8076ec6cc support expression-by-expression compilation
* module/language/ghil.scm (unparse-ghil): Fix unparsing of quasiquoted
  expressions.

* module/language/ghil/spec.scm (join): Define a joiner for GHIL.

* module/language/scheme/compile-ghil.scm (cenv-ghil-env): Expand the
  definition of a CENV so it can have an actual ghil-env, if available.
  (compile-ghil): Return the actual ghil env in the cenv.

* module/system/base/compile.scm (compile-file): Rewrite. `output-file'
  is now a keyword argument, along with the new kwargs `env' and `from'.
  We now allow exceptions to propagate up, and instead of printing the
  output file to the console, we return a string corresponding to its
  location.
  (compile-and-load): Use read-and-compile.
  (compile-fold): Thread around the cenv as well. Return all three
  values.
  (find-language-joint, read-and-compile): New exciting helpers. The idea
  is that compiling a file should be semantically equivalent to compiling
  each expression in it, one by one. Compilation can have side effects,
  e.g. affecting the current language or the current reader. So what we
  do is find a point in the compilation path at which different
  expressions of a given language can be joined into one. Expressions
  from the source language are compiled to the joint language, then
  joined and compiled to the target.
  (compile): Just return the first value from compile-fold.

* module/system/base/language.scm (language-joiner): New optional field.

* scripts/compile: Rework for changes to compile-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/ecmascript/compile-ghil.scm:
* module/language/ghil/compile-glil.scm:
* module/language/glil/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.

b15dea6857 Replace eval-case with eval-when
* module/ice-9/boot-9.scm (eval-when): Replace eval-case with eval-when.
  Eval-when is *much* simpler, and more expressive to boot. Perhaps in
  the future we'll get 'visit and 'revisit too.

* module/ice-9/deprecated.scm (eval-case): Provide mostly-working
  deprecated version of eval-case.

* module/ice-9/boot-9.scm (defmacro, define-macro): Relax condition: we
  can make defmacros that are not at the toplevel now. But in the future
  we should replace this implementation of defmacros with one written in
  syntax-case.
  (define-module, use-modules, use-syntax): Allow at non-toplevel.
  (define-public, defmacro-public, export, re-export): Don't evaluate at
  compile-time, I can't see how that helps things. Allow `export' and
  `re-export' at non-toplevel.

* module/ice-9/getopt-long.scm:
* module/ice-9/i18n.scm:
* module/oop/goops.scm:
* module/oop/goops/compile.scm:
* module/oop/goops/dispatch.scm: Switch to use eval-when, not
  eval-case.

* module/language/scheme/compile-ghil.scm (eval-when): Replace eval-case
  transformer with eval-when transformer. Sooooo much simpler, and it
  will get better once we separate expansion from compilation.

* module/language/scheme/expand.scm (quasiquote): Hm, expand quasiquote
  properly. Not hygienic. Syncase needed.
  (lambda): Handle internal defines with docstrings propertly.

3ac6d9f37e use -> macro in scheme->ghil compiler
* module/language/scheme/compile-ghil.scm (->): New macro, makes GHIL
  generation a bit more palatable. Use it in all the transformers.

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.

* module/language/ecmascript/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.

abd6af11cd generate the fixed-offset accessors at compile-time
* module/language/scheme/compile-ghil.scm (define-scheme-translator):
  Only add an else clause if the transformer didn't have one.

* module/oop/goops.scm (min-fixnum, max-fixnum): Define at compile-time
  as well.
  (@slot-ref, @slot-set!): Only define transformers for these at
  compile-time. Avoids loading up the compiler unnecessarily. Also, allow
  for the `n' to be determined lexically, in which case we dispatch to
  the primitive.
  (num-standard-pre-cache, define-standard-accessor-method)
  (bound-check-get, standard-get, standard-set): Rework the fixed-offset
  getters and setters so that they can be computed at compile-time.
  Accessors to fields with n > num-standard-pre-cache will be dispatched
  to the primitive instead of within the VM.

d9d671f76e no keyword arguments in GHIL / GLIL, just optional args -- faster compiles
* module/system/base/syntax.scm (define-record): So, in the generated
  constructors, allow optional arguments, but not keyword arguments.
  Conses much less in the constructors.
  (define-record/keywords): And the old define-record is here.

* module/language/ghil.scm (parse-ghil):
* module/language/ghil/compile-glil.scm (codegen):
* module/language/scheme/compile-ghil.scm (translate-1, quote)
  (quasiquote): Don't use keywords in this compiler hotpath.

* module/system/base/language.scm (<language>):
* module/system/repl/common.scm (<repl>):
* module/system/vm/debug.scm (<debugger>): Use define-record/keywords.

028e3d0666 propagate much more source info through compilation
* module/language/ghil/compile-glil.scm (codegen): Record source location
  for offset 0 into a lambda, if we can.

* module/language/scheme/compile-ghil.scm (translate-1)
  (define-scheme-translator): In the retrans procedures, propagate the
  location information from the enclosing expression if the subexpression
  has no location information. Gives source information to many more
  expressions.
  (location): Just propagate the source properties as they are, the
  glil->assembly compiler will interpret them.

* module/language/glil.scm (<glil>): Change glil-source to take "props"
  and not "loc", as it's the source properties that we're interested in.

* module/language/glil/compile-assembly.scm (limn-sources): New function,
  takes a list of addr-source property pairs and "compresses" them for
  serialization to disk.
  (glil->assembly): Limn the sources before writing them to disk. Avoid
  non-tail recursion when determining total byte length of code.

* module/system/vm/program.scm (source:file, source:line, source:column):
  Update for new source representation.
  (program-source): Export.
  (write-program): Nicer pretty-printing of anonymous procedures.

* libguile/backtrace.c (display_backtrace_get_file_line): Update for the
  new VM source representation.

* libguile/programs.h:
* libguile/programs.c (scm_program_sources): Update for the new
  serialized source representation, where the filename is not in the
  stream unless it changes.
  (scm_program_source): New exported function, looks up the source for a
  given ip offset.
  (scm_c_program_source): Update to return the last source information
  that was <= the given IP, because we only serialize source info when it
  changes.

dae318a631 nicety in the compiler

277f728b14 allow defmacros to unquote in macros into expanded expressions
* module/language/scheme/compile-ghil.scm (lookup-transformer): Allow
  macros to be unquoted into the car of any form that results from macro
  expansion. This lets modules export defmacros built on other defmacros
  that are not exported.

9892287960 minor cleanups
* libguile/stacks.c (scm_make_stack): Instead of aborting when we misread
  the number of stack frames, just print a warning. I'd like to figure
  out what these cases are, exactly.

* module/language/scheme/compile-ghil.scm (lambda): Reindent the lambda
  transformer.

* module/system/base/compile.scm (call-with-compile-error-catch): Write
  the expression instead of displaying it.
  (call-with-output-file/atomic): Don't actually redirect output to this
  port, as it's not necessary -- the language-printer should respect the
  port that we pass.

ca445ba5ec rename translate.scm to compile-ghil.scm, and more work on compiler.texi
* doc/ref/api-evaluation.texi: Fix some typos and xrefs.

* doc/ref/compiler.texi (The Scheme Compiler): Document the scheme
  compiler, and start documenting the GHIL language.

* doc/ref/guile.texi (Guile Implementation): Whoops, put autoconf after
  the implementation foo. Unless we want it before?

* doc/ref/history.texi (The Emacs Thesis): Fix typo.

* doc/ref/vm.texi (Environment Control Instructions): Rename offset to
  index.

* module/language/ghil.scm (parse-ghil): Fix what I think was a bug --
  the consumer in a mv-call shouldn't be a rest arg.

* module/language/scheme/Makefile.am (SOURCES):
* module/language/scheme/compile-ghil.scm: Rename this file from
  translate.scm.

* module/oop/goops.scm:
* module/language/scheme/spec.scm: Deal with renaming.
