* 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.
* 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/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.
* 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.
* 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.
* 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/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.
* 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.
* 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/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.
* gdbinit: Untested attempts to get the stack fondling macros to deal
with the new program representation.
* libguile/frames.c (scm_vm_frame_arguments, scm_vm_frame_source)
(scm_vm_frame_local_ref, scm_vm_frame_local_set_x): SCM_PROGRAM_DATA is
a struct scm_objcode*.
* libguile/instructions.h:
* libguile/instructions.c: Hide the instruction table and the struct
scm_instruction structure; all access to instructions now goes through
procedures. This is because instructions are no longer in a packed
array indexed by opcode. Also, declare a mask that all instructions
should fit in.
* libguile/objcodes.h:
* libguile/objcodes.c: Rewrite so that object code directly maps its
arity and length from its bytecode. This makes it unnecessary to keep
this information in programs, allowing programs to be simple conses
between the code (objcodes) and data (the object table and the closure
variables).
* libguile/programs.c (scm_make_program): Rework so that make-program
takes objcode, an object table, and externals as arguments. It's much
clearer this way, and we avoid malloc().
* libguile/stacks.c (is_vm_bootstrap_frame): Update for program/objcode
changes.
* libguile/vm-engine.c (vm_run): Initialize the jump table on the first
run, with the opcodes declared in the instruction sources, and with bad
instructions raising an error instead of wandering off into the
Unknown.
* libguile/vm-engine.h (FETCH_LENGTH): Always represent lengths as 3
bytes. The old code was too error-prone.
(NEXT_JUMP): Mask the instruction with SCM_VM_INSTRUCTION_MASK.
(NEW_FRAME): Update for program/objcode changes.
* libguile/vm-expand.h (VM_DEFINE_FUNCTION, VM_DEFINE_INSTRUCTION)
(VM_DEFINE_LOADER): Update so that we explicitly specify opcodes, so
that we have a stable bytecode API.
* libguile/vm-i-loader.c: Update license to LGPLv2+. Explicitly declare
opcodes.
(load-integer): Use an int instead of a long as the accumulator; still
need to revisit this code at some point, I think.
(load-program): Simplify, thankfully!! Just creates the objcode slice
and rolls with it.
* libguile/vm-i-scheme.c: Number the opcodes explicitly.
* libguile/vm-i-system.c: Update license to LGPLv2+. Explicitly declare
opcodes.
(make-closure): Update for new program API.
* libguile/vm.c (vm_make_boot_program): Update for new program/objcode
API. Still a bit ugly.
(scm_load_compiled_with_vm): Update for new program/objcode API.
* module/language/assembly.scm (byte-length): Fix byte-length calculation
for loaders, and load-program.
(code-pack, code-unpack): Start to move things from (system vm conv)
here.
(object->code, code->object): More things from conv.scm.
* module/language/glil.scm (<glil-program>): Add a new field,
closure-level.
(make-glil-program, compute-closure-level): Calculate the "closure
level" when making a glil program. This is the maximum depth of
external binding refs in this closure.
(unparse-glil): Fix label serialization.
* module/language/glil/compile-assembly.scm (make-meta): Prepend #f for
the meta's object table, though maybe in the future we can avoid
creating assembly in the first place.
(assoc-ref-or-acons, object-index-and-alist): GRRR! Caught again by the
different sets of arguments to assoc and assoc-ref!
(glil->assembly): Attempt to make the <glil-program> case more
readable, and fix the bugs. Sorry I don't know how to comment this
change any more than this.
(glil->assembly): For <glil-module> serialize the whole key, not just
the name.
(dump-object): subprogram-code is already a list. Serialize integers as
strings, not u8vectors. Fix the order of lists and vectors.
* module/language/glil/spec.scm (glil): Switch orders, so we prefer glil
-> assembly -> objcode. Actually glil->objcode doesn't work any more,
needs to be removed I think.
* module/language/objcode/spec.scm (objcode->value):
s/objcode->program/make-program/.
* module/language/scheme/inline.scm: Add acons inline.
* module/system/vm/conv.scm (make-byte-decoder): Skip the first 8 bytes,
they are header. Handle subprograms properly. Still needs help though.
(decode-length): Lengths are always 3 bytes now.
* module/system/vm/disasm.scm: Superficial changes to keep things
working. I'd like to fix this better in the future.
* module/system/vm/frame.scm (bootstrap-frame?): Fixes for
program-bytecode.
* module/system/vm/program.scm: Export make-program. It's program-objcode
now, no more program-bytecode.
* module/system/vm/vm.scm (vm-load): Use make-program.
* test-suite/tests/asm-to-bytecode.test: New test, very minimal.
* module/system/vm/objcode.scm: Export word-size, byte-order, and
write-objcode.
* doc/ref/vm.texi (Stack Layout): Update to remove references to the
"heap link".
* gdbinit: Update for "heap link" removal.
* libguile/frames.c:
* libguile/frames.h: Update macros and diagram for removal of "heap
link". As part of this, we also remove "heap frames", replacing them
with "vm frames", which are much like the interpreter's debug objects,
but for VM stacks. That is to say, they don't actually hold the stack
themselves, just the pointers into stack that's held by a continuation
(either captured or current).
* libguile/stacks.c (stack_depth, read_frames): Since a "stack" object is
really a copy of information that comes from somewhere else, it makes
sense to copy over info from the VM, just as `make-stack' does from the
evaluator. The tricky bit is to figure out how to interleave VM and
interpreter frames. We do that by starting in the interpreter, and
whenever the current frame's procedure is actually a program, we switch
to the VM stack, switching back when we reach a "bootstrap frame". The
last bit is hacky, but it does work...
(is_vm_bootstrap_frame): Hacky predicate to see if a VM frame is a
bootstrap frame.
(scm_make_stack): Accept a VM frame in addition to debug frames.
Probably has some bugs in this case. But in the case that the arg is
#t (a common case), do the right thing, capturing the top VM frame as
well, and interleaving those frames appropriately on the stack.
As an accident, we lost the ability to limit the number of frames in
the backtrace. We could add that back, but personally I always want
*all* frames in the trace... Narrowing still works fine, though there
are some hiccups sometimes -- e.g. an outer cut to a procedure that
does a tail-call in VM code will never find the cut, as it no longer
exists in the continuation.
* libguile/vm.h (struct scm_vm): So! Now that we have switched to save
stacks in the normal make-stack, there's no more need for `this_frame'
or `last_frame'. On the other hand, we can take this opportunity to fix
tracing: when we're in a trace hook, we set `trace_frame' on the VM,
so we know not to fire hooks when we're already in a hook.
(struct scm_vm_cont): Expose this, as make-stack needs it to make VM
frames from VM continuations.
* libguile/vm.c (scm_vm_trace_frame): New function, gets the current
trace frame.
(vm_mark, make_vm): Hook up the trace frame.
(vm_dispatch_hook): New hook dispatcher, with a dynwind so it does the
right thing if the hook exits nonlocally.
* libguile/vm-engine.c (vm_run): No more this_frame in the wind data.
* libguile/vm-engine.h (RUN_HOOK): Run hooks through the dispatcher.
(ALIGN_AS_NON_IMMEDIATE, POP_LIST_ON_STACK): Remove unused code.
(NEW_FRAME): Adapt for no HL in the frame.
* libguile/vm-i-system.c (goto/args, mv-call, return, return/values):
Adapt for no HL in the frame.
* module/system/vm/frame.scm:
* module/system/vm/vm.scm: Beginnings of some reworkings, needs more
thought.
* module/ice-9/boot-9.scm (default-pre-unwind-handler): Rename from
default-lazy-handler.
(pre-unwind-handler-dispatch): Rename from lazy-hadler-dispatch.
(error-catching-loop): Adjust caller.
* module/system/repl/repl.scm (default-pre-unwind-handler): Remove this
definition, in favor of the default one in boot-9.
(default-catch-handler): Don't do a vm-backtrace, as we will soon be
relying on core machinery to do that for us.
(call-with-backtrace): Start a new stack for the thunk.
(with-backtrace): Macro version of call-with-backtrace.
(start-repl): Use with-backtrace for brevity. Start a stack with #t as
the tag instead of repl-eval, because all traces of repl-eval are gone
after it does a tail-call.
* module/ice-9/debugger.scm:
* module/ice-9/debugging/traps.scm:
* module/ice-9/stack-catch.scm: Adapt to s/lazy/pre-unwind/ in
boot-9.scm.
* 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/il/ghil.scm (parse-ghil): Fix a typo for values*
(unparse-ghil): Only output (quote foo) if the object is a symbol.
(unparse-ghil): Fix some missing ,@.
* 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/vm/disasm.scm (disassemble-program): Don't print the
nargs= nrest= etc line, it's redundant.
* module/system/vm/program.scm (program-bindings-as-lambda-list): If the
program bindings is null, then that's that.
* 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.
* module/system/il/inline.scm (define-inline): Use @ when accessing
module vars so that other modules don't need to import all of our
modules. However case-lambda is still needed.
* 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.
* ice-9/boot-9.scm (compile-time-environment): New function, with
documentation. The trick is that the compiler recognizes calls to
(compile-time-environment) and replaces it with a representation of the
*available* lexicals. Note that this might not be all the lexicals;
only the heap-allocated ones are returned.
* module/language/scheme/translate.scm (custom-transformer-table):
Compile `compile-time-environment' to <ghil-reified-env>.
* module/system/il/compile.scm (codegen): Add <ghil-reified-env> clause,
which calls ghil-env-reify.
* module/system/il/ghil.scm (ghil-env-reify): New procedure, returns a
list of (NAME . EXTERNAL-INDEX).
(<ghil>): Add <ghil-reified-env> object.
* 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.
* gdbinit (pp, inst): New commands.
* libguile/vm-engine.c (vm_error_not_a_pair): New error case.
* libguile/vm-i-scheme.c (VM_VALIDATE_CONS): New macro -- use this
instead of SCM_VALIDATE_* because SCM_VALIDATE will exit nonlocally
before we have a chance to sync the regs.
(car, cdr, set-car, set-cdr): Use VM_VALIDATE_CONS.
* libguile/vm-i-system.c (goto/args): Bugfix: when doing a
self-tail-recursion, allocate fresh externals. Fixes use of match.go.
* module/system/vm/assemble.scm (dump-object!): Add some checks that we
aren't dumping out values that the VM can't handle.
* module/system/vm/disasm.scm (disassemble-externals): Fix rotten call to
`print-info'.
* oop/goops/dispatch.scm: Add a FIXME.
* testsuite/Makefile.am (vm_test_files):
* testsuite/t-closure4.scm (extract-symbols): New test, distilled with
much effort out of match.scm.
* ice-9/Makefile.am (NOCOMP_SOURCES): Re-enable compilation of match.scm.
Yay!
* module/system/vm/assemble.scm (make-temp-binding, btemp:name)
(btemp:extp, btemp:index): Don't abuse program.scm's make-binding to
make something that actually isn't a binding.
(codegen): Do use program.scm's make-binding to make something that
actually is a binding.
* module/system/vm/program.scm (binding:start, binding:end): New
accessors.
(make-binding): Expand to have the start and end arguments in the
constructor.
* module/system/vm/disasm.scm (disassemble-program): Fix misunderstanding
of nlocs: the *actual* number of locals is nlocs + nargs, even if the
arg is heap-allocated -- because our calling convention always puts the
initial val on the stack. Also: don't disassemble the objects, they are
now woven into the text.
(code-annotation): Fix external-{ref,set} handling to allow for
referencing externals from enclosed stack frames. Really this should be
statically determined, though. Add late-variable-{ref,set} handling.
* module/system/vm/assemble.scm (pop): Define a pop here too.
(codegen): Rework how bindings are represented in a program's
meta-info, so they declare their range in the binding list instead of
you having to figure out when they end.
* module/system/vm/conv.scm (make-byte-decoder): Return the end-address
as well; requires a change to callers.
* module/system/vm/disasm.scm (disassemble-objcode, disassemble-program)
(disassemble-bytecode, disassemble-objects, disassemble-externals)
(disassemble-meta, source->string, make-int16, code-annotation)
(print-info): Rework to display my domination of `format', and, more
seriously, start to integrate the "subsections" of the disassembly into
the main disassembly text.
* module/system/vm/program.scm (program-bindings-as-lambda-list): Update
for new bindings format; should be more correct.
