f3130a2ecf compiled-file-name tries to put the .go in the %load-compiled-path
* module/system/base/compile.scm (ensure-writable-dir): Rename from
  ensure-directory.
  (dsu-sort): Helper, does a decorate / sort / undecorate.
  (compiled-file-name): Refactor to only return a writable filename. The
  readable case is handled by load.c now, and the other case was silly.
  Hopefully it will do the right thing.
  (load-ensuring-compiled): Remove, load.c will call out to compile-file
  if necessary.
  (ensure-fallback-path): Remove, load.c will add the ~/.guile-ccache dir
  to the load-compiled path, which will prompt its creation if necessary.

4c9c9b9b98 install .go files under $libdir, not $datadir
* am/guilec: Install .go files to
  $(pkglibdir)/$GUILE_EFFECTIVE_VERSION/ccache.

34f3d47df9 add reader support for #; #` #' #, and #,@. fix bug in compile-and-load.
* libguile/read.c (flush_ws, scm_read_commented_expression)
  (scm_read_sharp): Add support for commenting out expressions with #;.
  (scm_read_syntax, scm_read_sharp): Add support for #', #`, #, and #,@.

* module/ice-9/boot-9.scm: Remove #' read-hash extension, which actually
  didn't do anything at all. It's been there since 1997, but no Guile
  code I've ever seen uses it, and it conflicts with #'x => (syntax x)
  from modern Scheme.

* module/system/base/compile.scm (compile-and-load): Whoops, fix a number
  of bugs here.

1351c2dba5 fix backtraces with compiled boot-9
* module/ice-9/boot-9.scm (default-pre-unwind-handler): Since we were
  tail-called by pre-unwind-handler-dispatch, we can't use
  pre-unwind-handler-dispatch as a narrowing argument. Instead just
  narrow by one frame.
  (pre-unwind-handler-dispatch): Deprecate.
  (error-catching-loop): Remove crack comment and code, and just use
  default-pre-unwind-handler as our pre-unwind handler.

* module/ice-9/stack-catch.scm (stack-catch):
* module/system/repl/repl.scm (call-with-backtrace): Use
  default-pre-unwind-handler directly.

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.

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

68623e8e78 remove compile-time-environment
* module/ice-9/boot-9.scm (guile-user): Move the `compile' autoload to
  the guile-user module. Remove reference to compile-time-environment.

* module/language/scheme/compile-ghil.scm:
* module/language/tree-il/compile-glil.scm:
* module/language/tree-il/optimize.scm:
* module/system/base/compile.scm:
* test-suite/tests/compiler.test: Remove definition of and references to
  compile-time-environment. While I do think that recompilation based on
  a lexical environment can be useful, I think it needs to be implemented
  differently. So for now we've lost nothing if we take it away, as it
  doesn't work with syncase anyway.

112edbaea3 inline calls to some primitives
* module/system/base/pmatch.scm: Wrap consequents in (let () ) instead of
  (begin ) so that they can have local definitions.

* module/language/tree-il/compile-glil.scm: Inline some calls to
  primitives.

7c72fe0bb5 ice-9 syncase now deprecated, woo
Remove #:use-module (ice-9 syncase) from lots of places, as it's no
longer needed.

8239263f86 fix erroneous #:use-syntax clausen
* module/system/repl/command.scm:
* module/system/repl/common.scm:
* module/system/repl/repl.scm:
* module/system/vm/debug.scm:
* module/system/vm/trace.scm: Change #:use-syntax to #:use-module, as
  that's really what we want to do.

c5cc65ac0c fix hygiene + modules + local macros
* module/ice-9/psyntax-pp.scm: Regenerate.

* module/ice-9/psyntax.scm (syntax-type): Look up the type of the car of
  a form relative to its module, if it is a syntax object. Fixes hygiene
  wrt modules and private macros.

* module/ice-9/syncase.scm (sc-macro): Add a comment.

* module/system/base/pmatch.scm: The big test case: just export pmatch,
  not ppat too.

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.

aa49787b5e Improved handling of callers cache in (system xref).
* We cache callees in each module, and keep a list of modified
    ('tainted') modules, which is used to reconstruct the callers
    database incrementally.
  * `procedure-callers' now returns an a-list, keyed by module name.

6ecae97fb8 fix duplicates in procedure-callers
* module/system/xref.scm (ensure-callers-db): OK! Since we can see the
  same variable twice, e.g. in different modules, keep a unified hash of
  seen vars and modules. Prevents duplicates in procedure-callers.
2009-03-28 22:21:00 -07:00
Andy Wingo
154a611669 fix spurious duplicates in procedure-callees and callers
* module/system/xref.scm (program-callee-rev-vars): It's possible to get
  duplicates when combining callees of inner procedures, so ignore dups.
  Quadratic, boo.

60ae5ca2a3 frame, program, objcode, etc inits use load-extension
* libguile/extensions.h: Define a scm_t_extension_init_func.

* libguile/frames.c:
* libguile/instructions.c:
* libguile/objcodes.c:
* libguile/programs.c:
* libguile/vm.c: Register extension init funcs. Should play nicer with a
  static Guile, in addition to working on Darwin with non-default
  installation prefixes without munging DYLD_LIBRARY_PATH.

* module/system/vm/frame.scm:
* module/system/vm/instruction.scm:
* module/system/vm/objcode.scm:
* module/system/vm/program.scm:
* module/system/vm/vm.scm: Use load-extension.

e0a3ad670b rework procedure-callers to stay correct as callees are redefined
* module/system/xref.scm (procedure-callers): Rework to calculate the
  callers of a *variable*, not of a value. This is because the
  module-observers only get fired when the module changes, not with the
  variables change values. Also accept either a variable, a symbol
  (resolved in the current module), or a modname . symname pair.

7eba9c99c2 doubly-weak callers db

Andy Wingo
b190790255 implement procedure-callers
* module/system/xref.scm: Implement procedure-callers, as the inverse of
  procedure-callees, with a cache invalidated by changes in modules.

* module/ice-9/boot-9.scm (module-use!): Don't poke module observers when
  module-use! is called for an already-used module.

Andy Wingo
4f96d42b2d add xref stub for interpreted procedures
* module/system/xref.scm (hacky-procedure-callees): Add a
  procedure-callees implementation for procedures with source, that
  currently does nothing. Not sure what to do, going into the future.
2009-03-17 23:16:35 +01:00
Andy Wingo
e04894e1ac add xref.scm
* module/system/xref.scm: New module, will provide callers/callees info.

* module/Makefile.am (SOURCES): Add xref.scm.

237f96e7f0 add separate expansion phase, to detwingle things a bit
* module/language/scheme/expand.scm: New module, implements a separate
  expansion phase, not interleaved with compilation.

* module/language/scheme/amatch.scm: Helper for expand.scm, it's pmatch
  with support for annotated source.

* module/ice-9/Makefile.am (SOURCES): Add annotate.scm to build list --
  early on because it will be used in the compiler.

* module/ice-9/annotate.scm: Fix the printer, default to unstripped
  (whatever that is), and add a deannotator.

* module/system/base/compile.scm (call-with-compile-error-catch): Fix for
  new representation of source locations.

* module/Makefile.am (SCHEME_LANG_SOURCES): Add amatch and expand.

3ca8401113 slight optimization in transform-record, note in optimize*
* module/language/ghil/compile-glil.scm (optimize*): Add a note.

* module/system/base/syntax.scm (transform-record): Access the common
  slots once at the beginning. Cuts down on the number of toplevel refs
  needed by the generated code.

89522052e2 introduce -> binding inside transform-record body expressions
* module/system/base/syntax.scm (transform-record): Introduce a ->
  binding inside the body, that produces records of the same type.

* module/language/ghil/compile-glil.scm (optimize*): Remove our ->ghil
  definition, as transform-record introduces a -> binding for us. Nice.

b106a3eddc first stabs as s-expression-driven transformation of GHIL
* module/language/ghil/compile-glil.scm (optimize*): Rewritten optimizer
  -- not yet in use, but it's closer to the code that I'd like to write.

* module/system/base/syntax.scm (transform-record): New crazy macro,
  makes GHIL a little less painful to work with.

Andy Wingo
2c65f2d5a7 use common slots mechanism in ghil
* module/system/base/syntax.scm (define-type): Fix getter for common
  slot.

* module/language/ghil.scm (<ghil>): Use the common slots mechanism.

Andy Wingo
43e0c29305 define-type has #:common-slots
* module/system/base/syntax.scm (define-type): Accept a #:common-slots

0704c81395 export procedure-arguments from ice-9 session
* module/system/vm/program.scm (program-arguments): New function, used by
  procedure-arguments.

* module/ice-9/session.scm (procedure-arguments): New exported function,
  returns an alist describing the given procedure.

3bb299b3f0 Aggregate makefiles for module/system' and module/language'.
* am/guilec (.scm.go): Create the target's directory, in case
  $(builddir) != $(srcdir).

* configure.in: Don't output any makefile under `module/system' or
  `module/language'.

* module/Makefile.am (SUBDIRS): Remove `language' and `system'.  Add `.'
  to the front.
  (modpath, SOURCES, SCHEME_LANG_SOURCES, ECMASCRIPT_LANG_SOURCES,
  GHIL_LANG_SOURCES, GLIL_LANG_SOURCES, ASSEMBLY_LANG_SOURCES,
  BYTECODE_LANG_SOURCES, OBJCODE_LANG_SOURCES, VALUE_LANG_SOURCES): New

c15fa41c0c unbork the repl

Andy Wingo
abf780e45e in meta-reader, return directly if the peeked char is EOF
* module/system/repl/repl.scm (meta-reader): If the (next-char #t)
  returns EOF, return that EOF directly, as it seems that with guile -q,
  the subsequent `read' actually waits for another C-d. Dunno why.

Andy Wingo
a56db0f67e use umask when making permissions on .go files
* module/system/base/compile.scm (call-with-output-file/atomic): Temp
  files get created 0600. After we're done writing, chmod them to
  something in line with the user's umask.

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.

Ludovic Courtès
73f4d8d1d2 Add -o'/--output' option to "guile-tools compile".
* module/system/base/compile.scm (compile-file): Add optional
  OUTPUT-FILE argument.

* scripts/compile (fail): New procedure.
  (%options): Add `-o'/`--output' option.
  (compile): Handle `-o'.
2009-02-21 00:38:06 +01:00
Ludovic Courtès
b96dac4d0e Change `compiled-file-name' to preserve the input file's directory.
* module/system/base/compile.scm (compiled-file-name): Prepend "(dirname
  file)" so that "guile-tools compile foo/bar.scm" produces
  "foo/bar.go", not "bar.go".
2009-02-14 22:17:47 +01:00
Andy Wingo
5a0df7be5f flush output when writing .go files
* module/system/base/compile.scm (call-with-output-file/atomic): Close
  the port we are writing to before renaming it, so that we flush output.
  Might fix some 0-length write errors that Jao was seeing.

Andy Wingo
34898db352 inline record predicates into record-case
* module/system/base/syntax.scm (record-case): Inline record predicates
  into the record-case. Shaves off a few more milliseconds from a GOOPS
  load.
2009-02-13 00:16:44 +01:00
Andy Wingo
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.
2009-02-13 00:01:47 +01:00
Andy Wingo
e14679bd52 speed up record-case
* module/language/ghil.scm: Whoops, export some unquote-splicing
  accessors that we didn't have exported before.

* module/system/base/syntax.scm: Speed up record-case, by syntactically
  determining the predicates and accessors. Nasty, in a way; but also
  much faster.
2009-02-11 22:08:04 +01:00
Andy Wingo
8899057d65 match bare literals with eq? in pmatch, not equal?
* module/system/base/pmatch.scm (ppat): Match atoms with eq?, not equal?.
  This speeds up compilation considerably, as we never match against
  numbers or strings or what-have-you. Note, you can match against
  literals with equal? via quoting the literal in the pattern.

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.

Andy Wingo
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.

e311f5fa04 tick in calls, procedure-name works on compiled procedures
* module/system/vm/program.scm:
* libguile/programs.h:
* libguile/programs.c (scm_program_bindings, scm_program_bindings)
  (scm_program_properties, scm_program_name): Unfortunately, implement
  more procs in C, so that C can use them more easily.

* libguile/debug.c (scm_procedure_name): Dispatch to scm_program_name as
  appropriate.

* libguile/vm-i-system.c (call): Tick in a call.

1f1ec13b5c add code for writing out metadata to the end of a program
* libguile/objcodes.c (make_objcode_by_mmap, scm_c_make_objcode_slice):
  Verify the lengths with the meta-length.
  (scm_objcode_meta): New procedure, for getting at the meta-info of an
  objcode.
  (scm_objcode_to_bytecode):
  (scm_write_objcode): Write bytecode with the metadata too.

* module/system/vm/objcode.scm: Export object-meta.

* module/language/assembly.scm (byte-length):
* module/language/assembly/compile-bytecode.scm (write-bytecode):
* module/language/assembly/decompile-bytecode.scm (decode-load-program):
* module/language/assembly/disassemble.scm (disassemble-load-program):
* module/language/glil/compile-assembly.scm (glil->assembly):
* test-suite/tests/asm-to-bytecode.test ("compiler"): Change to
  load-program format to have meta-or-#f instead of meta-length, so that
  we can serialize the meta as objcode without a load-program byte. Add a
  test for writing out the meta.

9bb8012dd6 remove conv.scm, disasm.scm; objcode->bytecode rename
* module/system/vm/Makefile.am:
* module/system/vm/conv.scm:
* module/system/vm/disasm.scm: Remove these modules, as their
  functionality is now in (language ...).

* libguile/objcodes.h:
* libguile/objcodes.c:
* module/system/vm/objcode.scm: Rename objcode->u8vector to
  objcode->bytecode.

* module/system/vm/frame.scm:
* module/language/bytecode/spec.scm: Fix for objcode->bytecode.

* scripts/disassemble:
* testsuite/run-vm-tests.scm: Fix for (system vm disasm) removal.

* module/system/repl/command.scm: Use the right disassembler.

d7236899f5 add disassembler that fits in with old compiler tower
* module/language/assembly/Makefile.am:
* module/language/assembly/disassemble.scm: Add a disassembler, based on
  the old one but fitting in with the decompiler tower.

* module/language/objcode/spec.scm (decompile-value): When decompiling
  programs, shove all the metadata that we know about into the "env".

* module/system/base/compile.scm (decompile-fold, decompile): Return the
  env from `decompile' as a second value. Not sure if `compile' should do
  this too.

7b107cceb9 add decompilers that can take us back to assembly
* module/language/assembly/Makefile.am:
* module/language/assembly/spec.scm:
* module/language/assembly/decompile-bytecode.scm: Add a bytecode
  decompiler. Neat!

* module/language/bytecode/spec.scm (decompile-objcode):
* module/language/objcode/spec.scm (decompile-value): Add some
  "decompilers" here too.

* module/system/base/compile.scm (current-language): Since we can refer
  to languages by name, do so here -- removes the previous
  anti-circularity hack.
  (compile-file, compile): Refer to target languages by name.
  (decompile): New public function. Neat!

* module/system/base/language.scm (lookup-decompilation-order): Fix so we
  look for decompilers with the high-level language definition.

5d6fb8bbeb allow specification of languages by name; add decompilers to languages
* module/system/base/language.scm (lookup-decompilation-order): New
  function, like its compiling cousin, but backwards.
  (compute-translation-order): Rework so that languages can be specified
  either by name or by identity. Return a list of language - procedure
  pairs, without the "to" language in the list, instead of a list of
  languages.
  (invalidate-compilation-cache!): Invalidate the decompilation cache
  too.
  (<language>): Add a decompiler field.

* module/system/base/compile.scm (compile-passes): Much simpler now that
  lookup-compilation-order gives us the procedures directly.

* module/language/*/spec.scm: Specify compilers by name, so that we can
  avoid unnecessary module loads, and so that when we specify
  decompilers, we can avoid cycles.
