* 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.
* module/system/base/language.scm (<language>): Rework so that instead of
hardcoding passes in the language, we define compilers that translate
from one language to another. Add `parser' to the language fields, a
bit of a hack but useful for languages with s-expression external
representations but with record internal representations.
(define-language, *compilation-cache*, invalidate-compilation-cache!)
(compute-compilation-order, lookup-compilation-order): Add an algorithm
that does a depth-first search for a translation path from a source
language to a target language, caching the result in a lookup table.
* module/language/scheme/spec.scm:
* module/language/ghil/spec.scm: Update to the new language format.
* module/language/glil/spec.scm: Add a language specification for GLIL,
with a compiler to objcode. Also there are parsers and printers, for
repl usage, but for some reason this doesn't work yet.
* module/language/objcode/spec.scm: Define a language specification for
object code. There is some sleight of hand here, in the "compiler" to
values; but there is method behind the madness, because this way we
higher levels can pass environments (a module + externals pair) to
objcode->program.
* module/language/value/spec.scm: Define a language specification for
values. There is something intellectually dishonest about this, but it
does serve its purpose as a foundation for the language hierarchy.
* configure.in:
* module/language/Makefile.am
* module/language/ghil/Makefile.am
* module/language/glil/Makefile.am
* module/language/objcode/Makefile.am
* module/language/value/Makefile.am:
Autotomfoolery for the ghil, glil, objcode, and value languages.
* module/language/scheme/translate.scm (translate): Import the bits that
understand `compile-time-environment' here, and pass on the relevant
portions of the environment to the next compiler pass.
* module/system/base/compile.scm (current-language): New procedure, refs
the current language fluid, or lazily sets it to scheme.
(call-once, call-with-output-file/atomic): Refactor these bits to use
with-throw-handler. No functional change.
(compile-file, compile-and-load, compile-passes, compile-fold)
(compile): Refactor the public interface of the compiler to be generic
and simple. Uses `lookup-compilation-order' to find a path from the
source language to the target language.
* module/system/base/syntax.scm (define-type): Adapt to changes in
define-record.
(define-record): Instead of expecting all slots in the first form,
expect them in the body, and let the first form hold the options.
* module/system/il/compile.scm (compile): Adapt to the compilation pass
API (three in and two out).
* module/system/il/ghil.scm (<ghil-var>, <ghil-env>)
(<ghil-toplevel-env>): Adapt to define-record changes.
* module/system/il/glil.scm (<glil-vars>): Adapt to define-record
changes.
(<glil>, print-glil): Add a GLIL record printer that uses unparse.
(parse-glil, unparse-glil): Update unparse (formerly known as pprint),
and write a parse function.
* module/system/repl/common.scm (<repl>): Adapt to define-record changes.
(repl-parse): New function, parses the read form using the current
language. Something of a hack.
(repl-compile): Adapt to changes in `compile'.
(repl-eval): Fix up the does-the-language-have-a-compiler check for
changes in <language>.
* module/system/repl/repl.scm (start-repl): Parse the form before eval.
* module/system/repl/command.scm (describe): Parse.
(compile): Be more generic.
(compile-file): Adapt to changes in compile-file.
(disassemble, time, profile, trace): Parse.
* module/system/vm/debug.scm:
* module/system/vm/assemble.scm: Adapt to define-record changes.
* module/language/scheme/translate.scm (receive): Fix an important bug
that gave `receive' letrec semantics instead of let semantics. Whoops!
* benchmark/measure.scm: Update for module changes.
* module/system/vm/Makefile.am: Update the set of modules needing
compilation.
* src/guile-vm.c: Bootstrap the VM, now that we have a function for it.
* testsuite/Makefile.am:
* testsuite/run-vm-tests.scm: Update to fix make check, broken since we
merged with Guile.
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.
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.
* module/language/scheme/translate.scm (trans-pair): In the `set!' case,
when a procedure-with-setter is passed, call `trans:pair' with an
actual pair. This fixes a long-lasting bug which prevented compilation
of `set!' statements with procedures-with-setter (this showed up when
compiling `(system vm assemble)').
* module/system/base/compile.scm: Added `objcode->u8vector' to the
`#:select' clause.
* module/system/base/syntax.scm: Cosmetic changes.
* module/system/vm/assemble.scm (preprocess): Removed debugging
statements.
* src/frames.c: Cosmetic changes.
* src/frames.h (SCM_FRAME_SET_DYNAMIC_LINK): New.
* src/objcodes.c: Use `scm_t_uint8' instead of `char' when relevant.
* src/vm.c (vm_heapify_frames_1): Use `SCM_FRAME_SET_DYNAMIC_LINK ()'.
* src/vm_loader.c: Added casts to mute GCC 4 warnings.
* testsuite/run-vm-tests.scm (*scheme*): Renamed to `%scheme'.
(run-test-from-file): Renamed to `compile/run-test-from-file'.
(run-vm-tests): Run each test using both the VM and the interpreter;
compare the results.
* testsuite/t-proc-with-setter.scm: Try out `get/set'.
* doc/Makefile.am (info_TEXINFOS): New.
* doc/guile-vm.texi: Added index entries and indices.
* doc/texinfo.tex: New file.
git-archimport-id: lcourtes@laas.fr--2005-mobile/guile-vm--mobile--0.6--patch-5
object file is too small.
* doc/guile-vm.texi: Documented `make-closure'. Improved the documentation
of `load-program'.
* testsuite: New directory.
* configure.in: Added `testsuite/Makefile' to `AC_OUTPUT'.
* Makefile.am (SUBDIRS): Added `testsuite'.
* src/vm_engine.h (VM_CHECK_OBJECT): New option.
(CHECK_OBJECT): New macro.
* src/vm_system.c (object-ref): Use VM_CHECK_OBJECT.
* module/system/vm/assemble.scm (preprocess): Commented out the debugging
code.
* benchmark/lib.scm (do-loop): New procedure.
