* libguile/vm-i-system.c (call): Rename continuation invocation from
`vm_call_cc' to `vm_call_continuation', because that's what it really
does. Add a note that it doesn't handle multiple values at the moment.
(goto/arg): Renamed from tail-call, in deference to the progenitors, on
Dale Smith's suggestion.
(goto/apply): New instruction, for `apply' in a tail context. Not yet
used, or vetted for that matter.
(call/cc): No need to pop the program, I don't think; although this
isn't tested either.
(goto/cc): New instruction, for call/cc in a tail context.
* module/language/scheme/translate.scm (*forbidden-primitives*): Rename
from %forbidden-primitives.
* module/system/il/compile.scm (codegen): Adapt to goto/args instead of
tail-call.
* module/system/il/inline.scm: Start inlining some macros used in
r4rs.scm -- not yet fully tested.
* ice-9/boot-9.scm: Allow load of a compiled r4rs file.
* libguile/frames.c (frame-mv-return-address): New accessor.
* libguile/frames.h: Update frame diagram.
(SCM_FRAME_UPPER_ADDRESS): Update for data area
growing by one pointer.
(SCM_FRAME_MV_RETURN_ADDRESS): New macro.
* libguile/vm-engine.h (NEW_FRAME): Update for frame getting bigger by a
pointer. In a normal NEW_FRAME, set the MV return address to NULL, to
indicate that this continuation does not accept multiple values.
* libguile/vm-i-system.c (tail-call): Update frame replacement code to
understand the MV return address.
(return): Make room for the MVRA.
* libguile/programs.c (program_print): Only try to lookup write-program
if the module system is booted.
* libguile/vm-engine.h (FREE_FRAME): Remove, it's now inlined everywhere.
* libguile/vm-i-system.c (tail-call): Inline FREE_FRAME, and implement
the calling bits here. Will make things more hackable.
* libguile/programs.h (struct scm_program):
* libguile/programs.c (scm_c_make_program): Record the current module
when making a program. This replaces the per-late binding recorded
module in the generated code, which should be more efficient, both in
terms of garbage, and in not calling resolve-module.
(program-module): New accessor.
* module/system/vm/program.scm: Add program-module to exports.
* libguile/vm-i-loader.c (link-later): Remove this instruction, since now
the entry in the object table is just a symbol, and can be loaded with
load-symbol.
* libguile/vm-i-system.c (late-variable-ref, late-variable-set): Rework
so as to look up in the module of the current program. The logic could
be condensed quite a bit if scm_module_lookup () knew what to do with
mod==#f.
* module/system/vm/assemble.scm (dump-object!): Dump <vlink-later> just
as load-symbol, as mentioned in the note on link-later.
* module/system/il/ghil.scm: Update comment to reflect the new reality.
* libguile/vm-i-system.c (late-variable-ref, late-variable-set): If the
module system isn't booted, do a simple scm_lookup. In the -ref case,
actually cache the variable location (doh!).
* ice-9/boot-9.scm: Only define load-compiled as #f if it's not already
defined, which won't normally be the case.
* libguile/guile-vm.c: Removed, there's no more guile-vm binary.
* libguile/frames.c: (with change frame? -> heap-frame?)
* libguile/frames.h:
* libguile/instructions.c:
* libguile/instructions.h:
* libguile/objcodes.c:
* libguile/objcodes.h:
* libguile/programs.c:
* libguile/programs.h:
* libguile/vm-bootstrap.h: (was bootstrap.h)
* libguile/vm-engine.c: (was vm_engine.c)
* libguile/vm-engine.h: (was vm_engine.h)
* libguile/vm-expand.h: (was vm_expand.h)
* libguile/vm-i-loader.c: (was vm_loader.c)
* libguile/vm-i-scheme.c: (was vm_scheme.c)
* libguile/vm-i-system.c: (was vm_system.c)
* libguile/vm.c:
* libguile/vm.h: These files moved here from src/, as guile-vm is now a
part of libguile.
* libguile/init.c: Bootstrap the VM. Yay!
* libguile/Makefile.am: The necessary chicanery here.
* module/system/vm/Makefile.am:
* module/system/vm/bootstrap.scm:
* 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:
* pre-inst-guile-env.in: Add builddirs to the load path; add module/ to
the path in the empty-$GUILE_LOAD_PATH case as well.
* src/Makefile.am: Moved out everything except guilec and guile-disasm,
which probably should be moved to the scripts directory?
* testsuite/Makefile.am: Update to find guile-vm in the right place.
* module/system/vm/Makefile.am:
* module/system/vm/bootstrap.scm: Removed bootstrap.scm, scm_init_guile
handles the bootstrapping for us.
* 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: Call the init functions in libguile; should
fix at some point to avoid the dlopen?
