* module/Makefile.am (BRAINFUCK_LANG_SOURCES): Compile at the end. Add
compile-tree-il.scm.
* module/language/brainfuck/compile-tree-il.scm: New compiler, compiles
to tree-il instead of scheme. I thought it would be more illustrative,
though there are some uncommented bits.
* module/language/brainfuck/parse.scm: Modify not to put a header on the
scheme representation. After all, we don't put <scheme> before scheme
code, do we? :)
* module/language/brainfuck/spec.scm: Add tree-il compiler.
* module/language/tree-il.scm: Understand (set! (lexical foo) ...).
* module/system/base/language.scm: Update license. Actually, updates
licenses on all these.
* libguile/filesys.h:
* libguile/filesys.c (scm_canonicalize_path): New function,
canonicalize-path.
* module/system/base/compile.scm (compiled-file-name): Canonicalize the
filename so that compiling e.g. ../foo.scm doesn't compile to
~/.guile-ccache/1.9/../foo.scm.
* libguile/load.c (compiled_is_fresh): Rename from compiled_is_newer.
Check that the mtines of the .go and .scm match exactly, so we don't
get fooled by rsync-like modifications of the filesystem.
* module/system/base/compile.scm (call-with-output-file/atomic): Add
optional arg, a reference file. If present we utime the output file to
match the source file, before the rename.
(compile-file): Stamp the .go file with the timestamp of the .scm.
* libguile/load.c (scm_init_load_path): Set the fallback path even if
GUILE_SYSTEM_COMPILED_PATH is set. Now that we store full paths in the
autocompiled files, and the path contains the effective Guile version,
there's no danger of accidental collisions.
(do_try_autocompile, autocompile_catch_handler, scm_try_autocompile):
Simplify again -- since there's only one place we put autocompiled
files, and compile-file finds it itself, there's no need to pass along
the compiled file path.
(scm_primitive_load_path): Don't call out to compiled-file-name to get
the fallback path, as we might not be autocompiling, and besides that
we need to check if the file exists at all.
* module/system/base/compile.scm (compiled-file-name): Simplify again.
The auto-compiled path is just fallback path + full source path + .go.
* module/system/base/compile.scm (compiled-file-name):
* libguile/load.c (scm_init_load_path, scm_try_autocompile)
(scm_primitive_load_path): Rework so that we search for .go files in
the load-compiled path and in the fallback path, but we only
autocompile to the fallback path. Should produce a more desirable experience.
* 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.
* 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.
* 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.
* 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.
* 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.
* 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.
* 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.
* 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.
* 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.
* 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.
* 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.
* 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.
* 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
variables, taken from former `Makefile.am' files in sub-directories.
* 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.
* 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.
* 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".
* 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.
* 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.
* 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.
* 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.
* 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.
* 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.
* 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.
* 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.
* 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!
* module/system/repl/common.scm (repl-print): Slightly refine the meaning
of "language-printer": a language printer prints an expression of a
language, not the result of evaluation. `write' prints values.
* module/language/ghil/spec.scm (ghil): Define a language printer, and a
translator for turning s-expressions (not scheme, mind you) into GHIL.
* module/language/scheme/translate.scm (quote, quasiquote): Add some
#:keyword action, so that we can (quote #:keywords).
* module/system/base/language.scm (<language>):
* module/system/base/compile.scm (read-file-in): Don't require that a
language have a read-file; instead error when read-file is called.
(compile-passes, compile-in): Refactor to call a helper method to turn
the language + set of options into a set of compiler passes.
* module/system/base/syntax.scm (define-type): Allow the type to be a
list, with the car being the name and the cdr being keyword options.
Interpret #:printer as a printer, and pass it down to...
(define-record): Here.
* module/system/il/ghil.scm (print-ghil, <ghil>): New printer for GHIL,
yay!
(parse-ghil, unparse-ghil): New lovely functions. Will document them in
the manual.
* module/system/base/compile.scm (call-with-nonlocal-exit-protect): New
helper, like unwind-protect but only for nonlocal exits.
(call-with-output-file/atomic): Use call-with-nonlocal-exit-protect so
that we don't mess up backtraces by catching all and then rethrowing.
Should fix this more comprehensively somewhere, though.
* ice-9/boot-9.scm (compile-time-environment): Remove definition from
boot-9 -- instead, autoload it and `compile' from (system base
compile).
* libguile/objcodes.h:
* libguile/objcodes.c (scm_objcode_to_program): Add an optional argument,
`external', the external list to set on the returned program.
* libguile/vm-i-system.c (externals): New instruction, returns the
external list. Only used by (compile-time-environment).
* libguile/vm.c (scm_load_compiled_with_vm): Adapt to
scm_objcode_to_program change.
* module/language/scheme/translate.scm (translate): Actually pay
attention to the environment passed as an argument.
(custom-transformer-table): Expand out (compile-time-environment) to
something that can be passed to `compile'.
* module/system/base/compile.scm (*current-language*): Instead of
hard-coding `scheme' in various places, use a current language fluid,
initialized to `scheme'.
(compile-file, load-source-file): Adapt to *current-language*.
(load-source-file): Ada
(scheme-eval): Removed, no one used this.
(compiled-file-name): Don't hard-code "scm" and "go"; instead use the
%load-extensions and %load-compiled-extensions.
(cenv-module, cenv-ghil-env, cenv-externals): Some accessors for
compile-time environments.
(compile-time-environment): Here we define (compile-time-environment)
to something that will return #f; the compiler however produces
different code as noted above.
(compile): New function, compiles an expression into a thunk, then runs
the thunk to get the value. Useful for procedures. The optional second
argument can be either a module or a compile-time-environment; in the
latter case, we can recompile even with lexical bindings.
(compile-in): If the env specifies a module, set that module for the
duration of the compilation.
* module/system/base/syntax.scm (%compute-initargs): Fix a bug where the
default value for a field would always replace a user-supplied value.
Whoops.
* module/system/il/ghil.scm (ghil-env-dereify): New function, takes the
result of ghil-env-reify and turns it back into a GHIL environment.
* scripts/compile (compile): Remove some of the tricky error handling, as
the library procedures handle this for us.
* test-suite/tests/compiler.test: Add a test for the dynamic compilation
bits.
* module/system/base/syntax.scm (define-type): Rework to not require the
`|', which confuses Emacs.
* module/system/il/ghil.scm (<ghil>):
* module/system/il/glil.scm (<glil>): Adapt to define-type changes.
* ice-9/boot-9.scm: Allow a compiled load of posix, networking, and
deprecated files.
* module/language/scheme/translate.scm (lookup-transformer): Lookup the
sc-macro by value, not by name. Works around the fact that compiled
macros don't have names, which is probably a bug.
* module/system/base/compile.scm (syntax-error)
(call-with-compile-error-catch): Throw and catch a key that's not used
by anyone else. Write error messages to the error port.
* module/system/repl/repl.scm (default-catch-handler): Call display-error
with the correct number of arguments.
* module/system/vm/frame.scm (frame-program-name): Guard against unbound
variables.
* ice-9/optargs.scm (let-keywords-template): Don't unquote in a helper
procedure. A bit irritating. I suppose we should fix the modules +
syncase situation at some point, and then switch to syncase.
* module/system/base/syntax.scm (keywords): Don't enable :keywords, it
breaks code that may assume that ':foo is a symbol, like boot-9.
* module/*.scm: Don't use :keywords, use #:keywords. The user can decide
if she wants #:keywords in their .guile, and :keywords might make us
compile modules differently.
Thanks to Dale Smith.
* guilec.mk: Rework to expect the includer to define $(modpath), then
make $(moddir) from that.
* module/language/Makefile.am:
* module/language/scheme/Makefile.am:
* module/system/base/Makefile.am:
* module/system/il/Makefile.am:
* module/system/repl/Makefile.am:
* module/system/vm/Makefile.am: Define modpath instead.
* src/guilec.in: Don't import (system vm bootstrap), it is no more.
* module/system/base/compile.scm (call-with-output-file/atomic): New
proc, outputs to a tempfile then does an atomic rename. Prevents SIGBUS
if a compiled file is truncated and rewritten, as the file's objcode is
mmap'd in.
(compile-file): Use the new helper.
This reorganization kills the ugly module-export-all hacks in
bootstrap.scm and core.scm. In fact, it gets rid of core.scm entirely,
breaking out its functionality into separate files.
* module/system/vm/trace.scm:
* module/system/vm/profile.scm:
* module/system/vm/disasm.scm:
* module/system/vm/debug.scm:
* module/system/vm/conv.scm:
* module/system/vm/assemble.scm:
* module/system/repl/repl.scm:
* module/system/repl/common.scm:
* module/system/base/compile.scm:
* module/system/repl/command.scm: Update for changes, and fix a bug in
procedure-documentation.
* module/system/vm/bootstrap.scm: Just call scm_bootstrap_vm, which
handles setting load-compiled for us.
* module/system/vm/core.scm: Removed, functionality folded into other
modules.
* module/system/vm/frame.scm: Export the C frame procedures here; also
move scheme functions from core.scm here.
* module/system/vm/instruction.scm: New file, exports procedures from
instructions.c.
* module/system/vm/objcode.scm: New file, exports procedures from
objcodes.c.
* module/system/vm/program.scm: New file, exports procedures from
programs.c, and some scheme functions originally from core.scm.
* module/system/vm/vm.scm: New file, from vm.c and core.scm.
* src/Makefile.am (libguile_vm_la_SOURCES): Add bootstrap.h.
* src/bootstrap.h: New file, prototypes scm_bootstrap_vm (), which the
scm_init_* functions call.
* src/frames.h:
* src/frames.c (scm_init_frames):
* src/frames.c (scm_bootstrap_frames):
* src/vm.h:
* src/instructions.h:
* src/instructions.c (scm_init_instructions):
* src/instructions.c (scm_bootstrap_instructions):
* src/objcodes.h:
* src/objcodes.c (scm_bootstrap_objcodes):
* src/objcodes.c (scm_init_objcodes):
* src/programs.h:
* src/programs.c (scm_bootstrap_programs):
