cases.

code.

* libguile/gsubr.h:
* libguile/gsubr.c (scm_i_primitive_call_ip):
* libguile/programs.c (scm_primitive_call_ip): Adapt to return an
absolute address.
* module/system/vm/assembler.scm (write-arity-headers): Adapt to write
byte addresses (relative to the text base).
* module/system/vm/debug.scm (arity-low-pc, arity-high-pc): Return
absolute addresses, instead of word offsets relative to the text
base.
(find-first-arity): Adapt for absolute addresses.
* module/system/vm/program.scm (program-arguments-alist): Adapt for
arity-low-pc / arity-high-pc absolute addresses.
* libguile/frames.c (scm_frame_source): Instead of assuming that
scm_frame_procedure is correct, use the IP to get the source.
(scm_frame_instruction_pointer): Return an absolute value instead of
assuming that slot 0 is correct. (It isn't, when preparing for a tail
call.)
* libguile/programs.h:
* libguile/programs.c (scm_find_source_for_addr): New internal helper.
* module/system/repl/debug.scm (print-registers): Readably print
absolute instruction pointers.
* module/system/vm/coverage.scm: Complete rewrite to use absolute IP's.
We can't assume that frame-procedure is cheap if it is correct, or
correct if it is cheap. Anyway using the address is better anyway.
(coverage-data->lcov): Disable per-function info temporarily.
(loaded-modules, module-procedures, closest-source-line)
(closed-over-procedures): Remove these. Instead of going from
procedures to source info, now we go from ELF image to source info.

* module/system/vm/program.scm (source-for-addr): New internal helper.
* module/system/vm/program.scm (program-arguments-alists): Export this
interface. Fall back to grovelling through procedure-minimum-arity if
the program has no arities, as might be the case for continuations.
* module/language/tree-il/analyze.scm (validate-arity): Use
program-arguments-alists instead of the program-arities interface, to
cover both stack VM and RTL programs.
* libguile/gsubr.c: Define RTL stubs instead of stack VM stubs.
(SUBR_STUB_CODE, get_subr_stub_code): Adapt to return a uint32_t*
pointer instead of a SCM value.
(create_subr): Create RTL procedures instead of stack VM procedures.
For RTL procedures, the function pointer, name, and generic address
pointer go inline to the procedure, as free variables.
(scm_i_primitive_arity, scm_i_primitive_call_ip): New helpers.
(scm_c_make_gsubr, scm_c_define_gsubr, scm_c_make_gsubr_with_generic)

(scm_i_rtl_program_documentation):

(scm_i_rtl_program_minimum_arity): Implement these appropriately for
primitives, which lack debugging information.
(scm_primitive_p, scm_primitive_call_ip): New helpers.
* libguile/snarf.h: Remove static allocation for subrs. Since there is
nothing to allocate besides the program itself, which needs runtime
relocation, static allocation is not a win.
* system/vm/program.scm: Fix up various arity-related things for
primitives, which don't use ELF arity info.
* test-suite/tests/eval.test ("stack involving a primitive"): Add an
XFAIL until we get just one VM.
* libguile/frames.c (scm_frame_source, scm_frame_instruction_pointer):
Fix to work with RTL programs.
* module/system/vm/debug.scm (find-debug-context): Allow for the
possibility of there being no ELF image.
(find-program-debug-info, find-program-arities)
(program-minimum-arity, find-program-docstring)
(find-program-properties, find-source-for-addr)

get the debug context.

(frame-call-representation): Allow RTL programs.
* module/system/vm/program.scm (program-arguments-alist): Placeholder
implementation for RTL programs.
(program-arguments-alists): Don't bail if we couldn't get the
arities.
* module/system/vm/debug.scm (find-program-sources): If there is no
source location before the low-pc of the procedure we're grovelling
for, we were skipping the source loc info. Fix that.
* module/system/vm/program.scm (write-program): Get source info for
anonymous RTL functions.
(program-sources, program-sources-pre-retire): Provide program
counters relative to the beginning of the procedure.

and let Scheme export the program-sources proper.

to write procedure property links out to a separate section.

* libguile/programs.h:
* libguile/programs.c (scm_i_rtl_program_properties):
* module/system/vm/debug.scm (find-program-properties): Wire up
procedure-properties for RTL procedures. Yeah! Fistpumps! :)
* module/system/vm/debug.scm (find-program-debug-info): Return #f if the
string is "", as it is if we don't have a name. Perhaps
elf-symbol-name should return #f in that case...
* test-suite/tests/rtl.test: Add some tests.
* libguile/procprop.h:
* libguile/procprop.c (scm_procedure_documentation): Move here from
procs.c, and to make the logic more similar to that of procedure-name,
which allows RTL programs to dispatch to rtl-program-documentation.
* libguile/programs.c (scm_i_rtl_program_documentation):
* libguile/programs.h:
* module/system/vm/program.scm (rtl-program-documentation): New
plumbing.

function.

procedures.

arities make it all the way to cold ELF and back to warm Guile.

to (system vm program).

* .gitignore: Ignore vm-operations.h.
* module/system/vm/instruction.scm:
* libguile/instructions.c:
* libguile/instructions.h: Use vm-operations.h to define enumerated
values for the new RTL opcodes. Define some helper macros to pack and
unpack 32-bit instruction words.
(rtl-instruction-list): New function, exported by (system vm
instruction).
* libguile/objcodes.c: Wire up the bits needed to detect the new RTL
bytecode and load it, as appropriate.
* doc/ref/api-procedures.texi (Compiled Procedures): Expand
program-arguments-alist and program-lambda-list documentation.
* module/system/vm/program.scm (arity->arguments-alist): Fix the rest
arg if there are also keyword args, a bug found while documenting!
* test-suite/tests/session.test ("procedure-arguments"): Update.
* libguile/programs.h:
* libguile/programs.c (scm_program_source): Add an optional arg, the
sources table to traverse. Defaults to the result of
scm_program_sources.
* module/system/vm/program.scm (program-sources-pre-retire): Move
definition here from (system vm traps), and export.
* module/system/vm/traps.scm: Adapt.

returns the source line corresponding to the next instruction instead
of the previous instruction.
* module/system/vm/program.scm (source:line-for-user): New exported
procedure, returns a 1-indexed line, suitable for presentation to a
user.
(write-program): Use source:line-for-user when making fallback names.

* module/language/assembly/disassemble.scm (source->string):
* module/system/repl/debug.scm (print-frame): Use source:line-for-user.
* libguile/programs.h:
* libguile/programs.c (scm_program_name): Remove. procedure-name is
sufficient.
* module/system/vm/program.scm (program-name): Remove from exports list.
(program-documentation): Remove; procedure-documentation is
sufficient.
* libguile/debug.c (scm_procedure_name): Remove special case for
programs.
* module/language/tree-il/analyze.scm (validate-arity): Use
procedure-name.
* module/ice-9/documentation.scm (object-documentation): Just use
procedure-documentation, without special cases for programs.
* libguile/programs.h:
* libguile/programs.c (scm_i_program_properties): Make internal.
(scm_program_name): Use scm_i_program_properties.
* libguile/procprop.c (scm_procedure_properties): Use
scm_i_program_properties, for programs.
* libguile/procs.c (scm_procedure_documentation): Use procedure-property
to get to 'documentation, not program-property.
* module/system/vm/program.scm (program-properties, program-property):
Remove from the exports list.
(program-documentation): Use procedure-property.
* module/texinfo/reflection.scm (macro-arguments)
(macro-additional-stexi)
(object-stexi-documentation): Use procedure-property, not
program-property.
* libguile/Makefile.am (lib_LTLIBRARIES): Instead of just "libguile.la",
make "libguile-@EFFECTIVE_VERSION@.la". This allows multiple versions
of Guile to be installed at once. See
http://www106.pair.com/rhp/parallel.html for a rationale.
(libguile_@GUILE_EFFECTIVE_VERSION@_la_CFLAGS):
(libguile_@GUILE_EFFECTIVE_VERSION@_la_SOURCES):
(EXTRA_libguile_@GUILE_EFFECTIVE_VERSION@_la_SOURCES):
(libguile_@GUILE_EFFECTIVE_VERSION@_la_DEPENDENCIES):
(libguile_@GUILE_EFFECTIVE_VERSION@_la_LIBADD):
(libguile_@GUILE_EFFECTIVE_VERSION@_la_LDFLAGS): Fixup automake vars
to include the effective version.
(guile_LDADD): Fix up the spelling of libguile.
* libguile/bytevectors.c (scm_bootstrap_bytevectors):
* libguile/foreign.c (scm_register_foreign):
* libguile/i18n.c (scm_bootstrap_i18n):
* libguile/instructions.c (scm_bootstrap_instructions):
* libguile/objcodes.c (scm_bootstrap_objcodes):
* libguile/programs.c (scm_bootstrap_programs):
* libguile/vm.c (scm_bootstrap_vm): Register extensions using e.g.
"libguile-2.0" as the libname -- i.e., including the effective version
in the libname.
* module/ice-9/i18n.scm:
* module/rnrs/bytevector.scm:
* module/rnrs/io/ports.scm:
* module/system/foreign.scm:
* module/system/vm/instruction.scm:
* module/system/vm/objcode.scm:
* module/system/vm/program.scm:
* module/system/vm/vm.scm: When doing a load-extension for something in
Guile, use the effective version also.
* meta/guile-2.0-uninstalled.pc.in (Libs):
* meta/guile-2.0.pc.in (Libs): Use -lguile-@EFFECTIVE_VERSION@. This
change should mean that code built against Guile should not be
affected by the libguile rename.
* guile-readline/Makefile.am (libguilereadline_v_@LIBGUILEREADLINE_MAJOR@_la_LIBADD):
* srfi/Makefile.am
(libguile_srfi_srfi_1_v_@LIBGUILE_SRFI_SRFI_1_MAJOR@_la_LIBADD):
(libguile_srfi_srfi_4_v_@LIBGUILE_SRFI_SRFI_4_MAJOR@_la_LIBADD):

(libtest_extensions_la_LIBADD):
(test_with_guile_module_LDADD):
(test_scm_with_guile_LDADD): Fix up the spelling of libguile.la.
* module/system/vm/program.scm (program-arguments-alist): Rename from
program-arguments, a name shadowed by features.c
(arglist->arguments-alist, arity->arguments-alist)
(arguments-alist->lambda-list, program-lambda-list, write-program):
Adapt callers.
* module/system/vm/frame.scm (frame-lookup-binding): Return #f if the
binding is not found, not an error.
(frame-binding-set!, frame-binding-ref): Adapt to error appropriately.
(frame-arguments): Dispatch to frame-call-representation.
(frame-call-representation): Refactor a bit.
* module/ice-9/session.scm (procedure-arguments): Adapt to
program-arguments name change.
* module/texinfo/reflection.scm (get-proc-args): Refactor to actually
work with VM procedures.
* libguile/_scm.h (SCM_OBJCODE_MINOR_VERSION): Bump.
* libguile/programs.h (SCM_PROGRAM_FREE_VARIABLES)
(SCM_PROGRAM_FREE_VARIABLE_REF, SCM_PROGRAM_FREE_VARIABLE_SET)
(SCM_PROGRAM_NUM_FREE_VARIABLES):
* libguile/programs.c (scm_make_program, scm_program_num_free_variables)
(scm_program_free_variable_ref, scm_program_free_variable_set_x):
Allocate free variables inline with programs, instead of being in a
vect. Should improve locality, and require fewer local variables in
the VM.
* libguile/vm-engine.c (vm_engine): Remove free_vars and free_vars_count
variables.
* libguile/vm-engine.h (CACHE_PROGRAM): No need to muck with free_vars
and free_vars_count.
(CHECK_FREE_VARIABLE): Update for inline free vars.
* libguile/vm-i-system.c (FREE_VARIABLE_REF): Update for inline free
vars.
(make-closure, fix-closure): Take the closure vals as separate stack
args, and copy or fix them inline into the appropriate closure.
* module/language/objcode/spec.scm (program-free-variables): Define a
local version of this removed function.
* module/language/tree-il/compile-glil.scm (flatten): Adjust to not make
a vector when making closures.
* module/system/vm/program.scm: Export program-num-free-variables,
program-free-variable-ref, program-free-variable-set!, and remove
program-free-variables.
* test-suite/tests/tree-il.test ("lambda"): Update to not make vectors
when making closures.
* gdbinit: Add gbt macro, to make a Guile backtrace whenever you want.
* module/system/vm/program.scm (program-arity): If ip is #f, just take
the first arity.
* module/system/vm/program.scm: Export the arity things again, and
program-arity. Why not.
* doc/ref/api-procedures.texi (Compiled Procedures): Update for current
API.
(Optional Arguments): Update to assume lambda* and define* are always
available, and (ice-9 optargs) is now the ghetto.
(Case-lambda): Now here, moved from SRFI-16 docs. Also docs
case-lambda*.
* doc/ref/srfi-modules.texi: Point to core case-lambda docs.
* module/language/glil/compile-assembly.scm (open-arity, close-arity)
(begin-arity, glil->assembly): Refactor so that arities can have
noncontiguous starts and ends. So within a prelude there is no arity
-- only before (the previous arity) or after (the new arity).
* module/system/vm/program.scm (arity:end): Add this private accessor.
Arities are expected to be in the new format. While not a change in
objcode format, it is an incompatible change, so I'll bump the objcode
cookie.
(program-arity): Check that the ip is within both bounds of the arity.
* libguile/_scm.h (SCM_OBJCODE_MINOR_VERSION): Bump.
* libguile/programs.c (scm_i_program_arity): Update for new arity format.
* module/system/vm/frame.scm (vm-frame-arguments): Avoid throwing an
error in this function, which is called from the backtrace code.
* libguile/objcodes.h: Bump for metadata format change.
* libguile/frames.h: Rework so we don't frob the program's nargs, nlocs,
etc at runtime. Instead we don't really know what's a local var, an
argument, or an intermediate value. It's a little unfortunate, but
this will allow for case-lambda, and eventually for good polymorphic
generic dispatch; and the nlocs etc can be heuristically
reconstructed. Such a reconstruction would be better done at the
Scheme level, though.
(SCM_FRAME_STACK_ADDRESS): New macro, the pointer to the base of the
stack elements (not counting the program).
(SCM_FRAME_UPPER_ADDRESS): Repurpose to be the address of the last
element in the bookkeeping part of the stack -- i.e. to point to the
return address.
* libguile/vm-engine.h:
* libguile/vm-i-system.c: Adapt to removal of stack_base. Though we
still detect stack-smashing underflow, we don't do so as precisely as
we did before, because now we only detect overwriting of the frame
metadata.
* libguile/vm-engine.c (vm_engine): Remove the stack_base variable. It
is unnecessary, and difficult to keep track of in the face of
case-lambda. Also fix miscommented "ra" and "mvra" pushes. Push the
vp->ip as the first ra...
* libguile/vm-i-system.c (halt): ...because here we can restore the
vp->ip instead of setting ip to 0. Allows us to introspect ips all
down the stack, including in recursive VM invocations.
* libguile/frames.h:
* libguile/frames.c (scm_vm_frame_stack): Removed, because it's getting
more difficult to tell what's an argument and what's a temporary stack
element.
(scm_vm_frame_num_locals): New accessor.
(scm_vm_frame_instruction_pointer): New accessor.
(scm_vm_frame_arguments): Defer to an implementation in Scheme.
(scm_vm_frame_num_locals scm_vm_frame_local_ref)
(scm_vm_frame_local_set_x): Since we can get not-yet-active frames on
the stack now, with our current calling convention, we have to add a
heuristic here to jump over those frames -- because frames have
pointers in them, not Scheme values.
* libguile/programs.h:
* libguile/programs.c (scm_program_arity): Remove, in favor of..
(scm_program_arities): ...this, which a list of arities, in a new
format, occupying a slot in the metadata.
* module/language/assembly/decompile-bytecode.scm (decode-load-program):
Fix mv-call decompilation.
* module/system/vm/frame.scm (vm-frame-bindings, vm-frame-binding-ref)
(vm-frame-binding-set!): New functions, to access bindings by name in
a frame.
(vm-frame-arguments): Function now implemented in Scheme. Commented
fairly extensively.
* module/system/vm/program.scm (program-bindings-by-index)
(program-bindings-for-ip): New accessors, parsing the program bindings
metadata into something more useful.
(program-arities, program-arguments): In a case-lambda world, we have
to assume that programs can have multiple arities. But it's tough to
detect this algorithmically; instead we're going to require that the
program metadata include information about the arities, and the parts
of the program that that metadata applies to.
(program-lambda-list): New accessor.
(write-program): Show multiple arities.
* module/language/glil/compile-assembly.scm (glil->assembly): Add
"arities" to the state of the compiler, and add arities entries as
appropriate.
* libguile/programs.h:
* libguile/programs.c: (SCM_PROGRAM_FREE_VARIABLES): Rename from
SCM_PROGRAM_FREE_VARS. Callers changed.
* libguile/programs.c (scm_make_program): Rename arg to
"free_variables".
(scm_program_free_variables): Rename from program-free-vars.
* libguile/vm-engine.h:
* libguile/vm-engine.c (VM_CHECK_FREE_VARIABLES): Rename from
VM_CHECK_CLOSURE.
(vm_engine, CACHE_PROGRAM): Rename closure and closure_count to free_vars and
free_vars_vount.
* libguile/vm-i-system.c (FREE_VARIABLE_REF): Rename from CLOSURE_REF.
(free-ref, free-boxed-ref, free-boxed-set): Rename from closure-ref,
closure-boxed-ref, closure-boxed-set.
(make-closure): Renamed from make-closure2.
* module/language/glil/compile-assembly.scm (glil->assembly): Hack to
never write out the the old "make-closure" instruction. Will fix
better later. Change to emit free-ref etc instead of closure-ref.
* module/language/tree-il/compile-glil.scm (flatten): Emit make-closure
instead of make-closure2, now that the old make-closure is gone.
* module/system/vm/program.scm (system): Rename program-free-vars to
program-free-variables.
* test-suite/tests/tree-il.test ("lambda"): Update for make-closure.
* libguile/frames.c (scm_frame_external_link): Removed.
* libguile/frames.h: No need to have the "external link" in the stack
frame -- update macros to take the new situation into account.
* libguile/objcodes.h (struct scm_objcode): Rename the nexts field to
"unused". In the future we can use it for nlocs, I think.
(SCM_OBJCODE_NEXTS): removed.
* libguile/programs.h:
* libguile/programs.c (scm_make_program): Expect the third argument to
be a vector of free variables, not a list of free variables.
SCM_BOOL_F indicates no free variables, not SCM_EOL.
(program_mark): Adapt.
(scm_program_arity): No more nexts.
(scm_program_free_vars): Replaces scm_program_externals.
* libguile/vm-engine.c (VM_CHECK_EXTERNAL)
(vm_engine): No need for the "external" var.
* libguile/vm-engine.h (CACHE_PROGRAM): Update for SCM_PROGRAM_FREE_VARS
instead of SCM_PROGRAM_EXTERNALS.
(NEW_FRAME): Update for new frame size, and no need to cons up
externals. Yay :)
* libguile/vm-i-loader.c (load-program): Update for scm_make_program.
* libguile/vm-i-system.c (external-ref, external-set): No more.
(make-closure): No more.
(goto/args): No need to re-cons externals here. Update for new stack
frame size.
(mv-call, return, return/values): Update for new frame size. No need
to reinstate externals on return.
* libguile/vm.c (really_make_boot_program, scm_load_compiled_with_vm):
Update for scm_make_program.
* module/language/objcode/spec.scm (objcode-env-externals): Treat '() as
#f, for the externals. Need to clean this up later...
* module/system/vm/program.scm (arity:nexts): Remove. Rename
program-external to program-free-vars.
* 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.
* 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.
* 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.
* 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.
* 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.
* 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/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.
