* 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!
* libguile/vm-engine.h (CHECK_STACK_LEAK, NULLSTACK): Add a new mode,
VM_ENABLE_STACK_NULLING, that tries to ensure that all stack data past
the top of the stack is NULL. This helps to verify the VM's
consistency. If VM_ENABLE_STACK_NULLING is not defined, there is no
overhead.
(DROP, DROPN): Hook into NULLSTACK.
(POP_LIST): Hoo, fix a good bug: if CONS triggered a GC, the elements
of the list that had not yet been consed would not be marked, because
the sp was already below them.
(NEXT): Hook into CHECK_STACK_LEAK.
(INIT_ARGS): Add a note that consing the rest arg can cause GC.
(NEW_FRAME): Cons up the external data after initializing the frame, so
that if GC is triggered, the precise marker sees a well-formed frame.
* libguile/vm-i-loader.c (load-program): In the four-integers case, use
the POP macro so that we can hook into NULLSTACK (if necessary).
* libguile/vm-i-scheme.c (ARGS2, ARGS3): Hook into NULLSTACK.
* libguile/vm-i-system.c (halt): Null the nvalues. Rework some asserts
into using ASSERT, and null the stack when we free the frame.
(variable-set): Use DROPN instead of sp -= 2.
(BR): Hook into NULLSTACK.
(goto/args): Hook into NULLSTACK. In the non-self case, delay updating
the frame until after INIT_ARGS so that GC sees a well-formed frame.
Delay consing the externals until after the frame is set up, as in
NEW_FRAME.
(call/cc): Add some asserts.
(return): Rework some asserts into ASSERT, and hook into NULLSTACK.
(return/values): Hook into NULLSTACK, and use ASSERT.
(return/values*) Use ASSERT.
* libguile/vm.c (VM_ENABLE_ASSERTIONS, VM_ENABLE_STACK_NULLING): These
are the variables that control assertions and nulling. Perhaps we can
do these per-engine when we start compiling the debug engine separate
from a speedy engine.
(vm_mark_stack): Add a precise stack marker. Yay!
(vm_cont_mark): Mark the continuation stack precisely.
(capture_vm_cont): Record the difference from the vp's stack_base too,
so that we can translate the dynamic links when marking the
continuation stack. Memset the stack to NULL if we are doing nulling.
(reinstate_vm_cont): If we are nulling, null out the relevant part
of the stack.
(vm_reset_stack): When resetting sp due to a nonlocal exit, null out
the stack too.
(vm_mark): If we are nulling, assert that there are no extra values on
the stack. Mark the stack precisely.
* libguile/vm-i-scheme.c (FUNC1): Remove, cause it's not used.
(FUNC2): Don't assume an inum can fit into an int, use scm_bits_t
instead. In reality though we should probably do use different checks,
i.e. for multiplication probably we overflow. (That would be a bug.)
Based on a patch by C. K. Jester-Young <cky944 <at> gmail.com>.
* 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/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/objcode.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?
