compiler, and start documenting the GHIL language.

the implementation foo. Unless we want it before?

* doc/ref/vm.texi (Environment Control Instructions): Rename offset to
index.
* module/language/ghil.scm (parse-ghil): Fix what I think was a bug --
the consumer in a mv-call shouldn't be a rest arg.
* module/language/scheme/Makefile.am (SOURCES):
* module/language/scheme/compile-ghil.scm: Rename this file from
translate.scm.

documenting compiled procedures.
* doc/ref/compiler.texi (Compiling to the Virtual Machine): Flesh out
with some structure, though much of the text remains to be written.
This stuff is hard to write!
* 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.
* doc/ref/vm.texi: Flesh out the VM documentation, adding a rationale.
* doc/ref/history.texi: Write the Guile history.
* doc/ref/guile.texi (Top): Some tweaks.
This reverts commit e563095988, which is
appropriate because subscription is not now required for someone to
send a message to bug-guile@gnu.org.
Conflicts:
* doc/ref/compiler.texi: A new empty section on the compiler.
* doc/ref/data-rep.texi: Made to be a section of a chapter instead of an
appendix. The beginnings of some revision, but not there yet.

"History and Implementation Details" chapter.
* doc/ref/history.texi: New empty section on Guile history.

instead of R4RS. Explicitly say that the full documentation is in
Texinfo (as other GNU packages do).
When you use GDS to evaluate Scheme code from Emacs, you can now use
`C-u' to indicate that you want to single step through that code. See
`Evaluating Scheme Code' in the manual for more details.
* scheme-using.texi (Evaluating Scheme Code): Document use of
`C-u' prefix with evaluation commands.
* gds-scheme.el (gds-eval-region, gds-eval-expression)
(gds-eval-defun, gds-eval-last-sexp): Support `C-u' prefix,
meaning that user wants to single step through the code.
* gds-client.scm (handle-nondebug-protocol): Add support for
setting a trap on code that is about to be evaluated.
* acconfig.h: Removed.
* acinclude.m4: Use the extended AC_DEFINE for HAVE_LABELS_AS_VALUES, so
as to remove the need for acconfig.h.
* autogen.sh: Use autoreconf.
* configure.in: Update info, don't warn about non-gnu make, bump version
to 0.7.

git-archimport-id: lcourtes@laas.fr--2005-mobile/guile-vm--mobile--0.6--patch-6
* 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)').

Before leaving the function, release OBJECTS_HANDLE.
