* libguile/bytevectors.h (SCM_BYTEVECTOR_HEADER_SIZE): Bump, giving
bytevectors another word: a parent pointer. Will allow for
sub-bytevectors and efficient mmap bindings.
* libguile/bytevectors.c (make_bytevector):
(make_bytevector_from_buffer): Init parent to #f.
(scm_c_take_bytevector, scm_c_take_typed_bytevector): Another
argument, the parent, which gets set in the bytevector.
* libguile/foreign.c (scm_pointer_to_bytevector): Use the parent field
instead of registering a weak reference from bytevector to foreign
pointer.
* libguile/objcodes.c (scm_objcode_to_bytecode): Use the parent field to
avoid copying the objcode.
* libguile/srfi-4.c (DEFINE_SRFI_4_C_FUNCS):
* libguile/strings.c (scm_from_stringn):
* libguile/vm.c (really_make_boot_program):
* libguile/r6rs-ports.c (scm_get_bytevector_some)
(scm_get_bytevector_all, bytevector_output_port_procedure): Set the
parent to #f.

* libguile/srfi-14.c:
* libguile/stacks.c:
* libguile/strings.c:
* libguile/throw.c:
* libguile/vm.c: Use scm_from_latin1_symboln to make symbols from string
literals, because they aren't in the user's locale -- they are in
ASCII, and we can optimize this case.
* libguile/vm-i-loader.c: Also use scm_from_latin1_symboln when loading
narrow symbols.
* libguile/debug.c:
* libguile/eval.c:
* libguile/frames.c:

fit a pointer into a long.
* libguile/vm-i-scheme.c (INUM_MAX, INUM_MIN): New macros.
(add1, sub1): Add/subtract without untagging the operand. This leads
to a 44% run time improvement compared to the previous
implementation.
* libguile/vm.c: Include <stdint.h>.
* test-suite/tests/numbers.test ("1+", "1-"): Add tests for
MOST-POSITIVE-FIXNUM, resp. MOST-NEGATIVE-FIXNUM, for 32-bit and
34-bit values thereof.

guile.

entering the engine.
* libguile/script.c (scm_compile_shell_switches): Select the debugging
VM in the cases that we previously would select deval -- when running
interactively without --no-debug, or otherwise with --debug.
* libguile/vm.c: Default to the regular engine.
(scm_c_set_vm_engine_x): Remove requirement for the VM to have no
pending computations.
* libguile/vm.h (scm_c_vm_run): Make internal.
* libguile/vm.c (vm_default_engine): New static global variable.
(make_vm): Set vp->engine based on
(scm_vm_apply): Remove in favor of call-with-vm.
(scm_thread_vm, scm_set_thread_vm_x): Remove these, as they did not
have a well-defined meaning, and were dangerous to call on other
threads.
(scm_the_vm): Reinstate previous definition.
(symbol_to_vm_engine, vm_engine_to_symbol)
(vm_has_pending_computation): New helpers.
(scm_vm_engine, scm_set_vm_engine_x, scm_c_set_vm_engine_x): New
accessors for VM engines.
(scm_c_set_default_vm_engine_x, scm_set_default_vm_engine_x): New
setters for the default VM engine.
(scm_call_with_vm): New function, applies a procedure to arguments in
a context in which a given VM is current.
* libguile/eval.c (eval, scm_apply): VM dispatch goes through
scm_call_with_vm.
* test-suite/tests/control.test ("the-vm"):
* module/system/vm/coverage.scm (with-code-coverage): Use call-with-vm.
* module/system/vm/vm.scm: Update exports.
* test-suite/vm/run-vm-tests.scm (run-vm-program):
* test-suite/tests/compiler.test ("current-reader"): Just rely on the
result of make-program being an applicable.
* test-suite/tests/eval.test ("stack overflow"): Add a note that this
test does not test what it should.
* libguile/vm.c (vm_dispatch_hook): Take care of FRAME's alignment
explicitly so that it's correct even if the current stack frame isn't
8-byte aligned (as can be the case on i686--the SysV i386 ABI just
says that the stack is word-aligned.)
* libguile/vm-i-system.c (call_cc, tail_call_cc): Call the new
RESTORE_CONTINUATION_HOOK when a continuation is restored.
(prompt): Call the new ABORT_CONTINUATION_HOOK when entering the abort
handler's continuation.
* libguile/vm-engine.h (ABORT_CONTINUATION_HOOK)
(RESTORE_CONTINUATION_HOOK):
* libguile/vm.h (SCM_VM_ABORT_CONTINUATION_HOOK)
(SCM_VM_RESTORE_CONTINUATION_HOOK):
* libguile/vm.c: (scm_vm_abort_continuation_hook): New hook, called when
entering an abort handler.
(scm_vm_restore_continuation_hook): New hook, called after returning
to a continuation.
* module/system/vm/vm.scm: Add hooks to export list.

useless hooks.
* libguile/vm.c (scm_vm_push_continuation_hook)
(scm_vm_pop_continuation_hook): New accessors.
* libguile/vm-i-system.c: Remove boot, halt, break, enter, exit, and
return hooks. Also remove the break instruction. Instead now when we
push a new continuation onto the stack we call PUSH_CONTINUATION_HOOK,
and when we pop via a return we call POP_CONTINUATION_HOOK. APPLY_HOOK
is now decoupled from continuation pushes and pops.
* libguile/vm-engine.h:
* libguile/vm-engine.c: Adapt for hooks.
* module/system/vm/trace.scm (vm-trace): Adapt for hooks. Also revive
the #:instructions? #t mode.
* module/system/vm/vm.scm: Adapt exports for new set of hooks.
* libguile/vm-i-scheme.c (ALIGNED_P): New macro.
(BV_FIXABLE_INT_REF, BV_INT_REF, BV_FLOAT_REF, BV_FIXABLE_INT_SET,
BV_INT_SET, BV_FLOAT_SET): Check the alignment of the pointer instead
of checking "i % size == 0". This fixes bus errors on
`sparc64-linux-gnu'.

* libguile/_scm.h (struct scm_aligned_cell)[__GNUC__]: New type.
(union scm_aligned_cell)[!__GNUC__]: New type.

* test-suite/tests/eval.test ("stack overflow"): New test prefix.
* 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.

in the libname.

* module/system/foreign.scm:

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):

* libguile/debug.h:
* libguile/debug.c (scm_sys_start_stack): Removed, we implement this in
Scheme now.
* libguile/vm.h:
* libguile/vm.c (scm_vm_call_with_new_stack): Likewise removed.
* module/ice-9/boot-9.scm (%start-stack): Implement in terms of prompts.
(%stacks): New fluid, for tracking active stacks.
(start-stack): Implement using syntax-rules.
* libguile/control.h (SCM_PROMPT_HANDLER): Remove, it was unused.
(SCM_PROMPT_DYNWINDS): Rename from SCM_PROMPT_DYNENV.
* libguile/control.c: (scm_c_make_prompt): Take another arg, the winds
that are to be in place for the prompt. Fix allocation to be 4 words
instead of 5 (the handler was never used).
* libguile/eval.c (eval):
* libguile/throw.c (pre_init_catch): Adapt to scm_c_make_prompt change.
* libguile/vm-i-system.c (partial-cont-call): Grovel the new elements of
the wind list in order to call setjmp() on the new prompts. Pass
cookie to vm_reinstate_partial_continuation.
(prompt): Adapt to scm_c_make_prompt change.
* libguile/vm.c (vm_reinstate_partial_continuation): Take a cookie arg,
used when winding captured prompts onto the stack. Winding a prompt
implies making a new prompt, actually -- with new registers, a new
jump buffer, new winds, etc.
* test-suite/tests/control.test ("rewinding prompts"): Add a test for
rewinding prompts.
* libguile/control.c (cont_objcode):
* libguile/vm-i-system.c (partial-cont-call):
* libguile/vm.c (vm_reinstate_partial_continuation): Don't keep the
"external winds" in a partial continuation, as they aren't logically
part of the continuation. Reinstate the "internal winds" when entering
a partial continuation. Things seem to work!
* libguile/vm-i-system.c (partial-cont-call): Sync registers before
splatting a partial continuation, and cache them back afterwards.
* libguile/vm.c (vm_reinstate_partial_continuation): Actually implement,
except dynamic-wind.
* libguile/control.c (cont_objcode): Along with a bunch of boilerplate
that certainly needs to go in some central place, define this
continuation-calling trampoline.
(reify_partial_continuation): New function, returns a procedure that
when called will reinstate a partial continuation.
(scm_c_abort): Take an extra arg, the cookie. Actually reify a
continuation.
(scm_at_abort): Adapt to scm_c_abort change.
* libguile/control.h: Declare scm_c_abort change.
* libguile/vm-i-system.c (partial_cont_call): New instruction.
(call/cc, tail-call/cc): Adapt to scm_i_vm_capture_stack change.
(abort): Pass vm_cookie to abort.
* libguile/vm.h (SCM_F_VM_CONT_PARTIAL, SCM_F_VM_CONT_REWINDABLE): New
flags.
(struct scm_vm_cont): Add flags field.
(SCM_VM_CONT_PARTIAL_P, SCM_VM_CONT_REWINDABLE_P): New predicates.
* libguile/vm.c (scm_i_vm_capture_stack): Rename from
vm_capture_continuation, and make internal instead of static. Take a
flags argument.
(scm_i_vm_capture_continuation): Adapt to scm_i_vm_capture_stack
change.
(vm_abort): Plumb cookie to scm_c_abort.
(vm_reinstate_partial_continuation): New stub.
* libguile/control.h:
* libguile/control.c (scm_c_make_prompt): Take an extra arg, a cookie.
Continuations will be rewindable only if the abort has the same cookie
as the prompt.
(scm_at_abort): Redefine from scm_abort, and instead of taking rest
args, take the abort values as a list directly. Also, don't allow
rewinding, because we won't support rewinding the C stack with
delimited continuations.
* libguile/eval.c (eval): Adapt to scm_c_make_prompt change.
* libguile/vm-engine.c (vm_engine): Use vp->cookie to get a unique value
corresponding to this VM invocation.
* libguile/vm-i-system.c (prompt): Pass the cookie to scm_c_make_prompt.
(abort): Take an additional tail arg.
* libguile/vm.c (vm_abort): Parse out the abort tail arg. This is for
the @abort case, or the (apply abort ...) case.
(make_vm): Initialize the cookie to 0.
* libguile/vm.h (struct scm_vm): Add cookie.
* module/ice-9/boot-9.scm (abort): Define here as a trampoline to
@abort. Needed to make sure that a call to abort dispatches to a VM
opcode, so the cookie will be the same.
* module/language/tree-il.scm (<tree-il>): Add a "tail" field to
<abort>, for the (apply abort ...) case, or (@abort tag args). Should
be #<const ()> in the normal case. Add support throughout.
* module/language/tree-il/analyze.scm (analyze-lexicals): Add abort-tail
support here too.
* module/language/tree-il/compile-glil.scm (flatten): Compile the tail
argument appropriately.
* module/language/tree-il/primitives.scm (*primitive-expand-table*): Fix
@abort and abort cases to pass the tail arg to make-abort.
* libguile/control.h:
* libguile/control.c (scm_c_abort): Add an implementation of `abort',
but it doesn't reify the continuation yet.
* libguile/vm-i-system.c (abort):
* libguile/vm.c (vm_abort): Wire up the call to `abort', avoiding
consing the args into a list.
* module/language/tree-il/compile-glil.scm (flatten): Add some compily
bits that can allow the abort to be resumed.
* libguile/vm.h (struct scm_vm_cont): Instead of saving the "IP", save
"RA" and "MVRA". That is, save singly-valued and multiply-valued
return addresses, so that we can return multiple values on the stack.
(scm_i_vm_reinstate_continuation): Remove.
* libguile/vm.c (vm_capture_continuation): Rename from capture_vm_cont,
and change the prototype so we can capture the RA and MVRA, and so
that tail calls to call/cc can capture a continuation without the
call/cc application frame.
(vm_return_to_continuation): Rename from reinstate_vm_cont, and take
arguments to return to the continuation. Handles returning to single
or multiple-value RA.
(scm_i_vm_capture_continuation): Change to invoke
vm_capture_continuation. Kept around for the benefit of make-stack.
* libguile/vm-i-system.c (continuation-call): Handle reinstatement of
the VM stack, with arguments.
(call/cc, tail-call/cc): Adapt to new vm_capture_continuation
prototype. tail-call/cc captures tail continuations.
* libguile/stacks.c (scm_make_stack): Update for scm_vm_cont structure
change.
* libguile/continuations.h (struct scm_contregs): Remove throw_value
member, which was used to return a value to a continuation.
(scm_i_check_continuation): New internal function, checks that a
continuation may be reinstated.
(scm_i_reinstate_continuation): Replaces scm_i_continuation_call; just
reinstates the C stack.
(scm_i_contregs_vm, scm_i_contregs_vm_cont): New internal accessors.
* libguile/continuations.c (scm_i_make_continuation): Return
SCM_UNDEFINED if we are returning again.
(grow_stack, copy_stack_and_call, scm_dynthrow): Remove extra arg, as
vm opcodes handle value returns.
(copy_stack): No need to instate VM continuation.
(scm_i_reinstate_continuation): Adapt.
* libguile/continuations.h:
* libguile/continuations.c (scm_i_make_continuation): Take VM and VM
continuation arguments as well; I'm not convinced that saving all VM
continuations was the right thing, and in any case we only ever saved
the latest. Running a new VM should create a continuation barrier.
* libguile/stacks.c (scm_make_stack):
* libguile/vm-i-system.c (call/cc, tail-call/cc): Adapt callers.
* libguile/vm.h (scm_i_vm_capture_continuation)
(scm_i_vm_reinstate_continuation): Change to be internal, and to only
capture and reinstate continuations for a particular VM.
* libguile/vm-i-system.c (prompt, wind, throw, unwind):
New instructions, for implementing dynamic-wind and delimited
continuations.
* libguile/vm.c: Add some stub support for the new instructions.
* libguile/vm-engine.c: Some new error conditions.
* libguile/smob.c: Instead of having special evaluator support for
applying smobs, we use the same strategy that gsubr uses, that smob
application should happen via a trampoline VM procedure, which uses a
special opcode (smob-apply). So statically allocate all of the desired
trampoline procedures here.
(scm_i_smob_apply_trampoline): Unfortunately there's no real place to
put the trampoline, so instead use a weak-key hash. It's nasty, but I
think the benefits of speeding up procedure calls in the general case
are worth it.
* libguile/smob.h (scm_smob_descriptor): Remove fields apply_0, apply_1,
apply_2, and apply_3; these were never public. Also remove the
gsubr_type field. Instead cache the trampoline objcode here.
(SCM_SMOB_APPLY_0, SCM_SMOB_APPLY_1, SCM_SMOB_APPLY_2,
SCM_SMOB_APPLY_3): Just go through scm_call_0, etc here.
* libguile/vm-i-system.c (call, tail-call, mv-call): Simplify. All
procedure calls are VM calls now.
(smob-call): New instruction, used in smob trampoline procedures.
* libguile/vm.c (apply_foreign): Remove. Yay!
* libguile/procprop.c (scm_i_procedure_arity): Refactor a bit for the
smob changes.
* libguile/tags.h (scm_tc7_gsubr): Return to the pool of unused tc7s, as
there are no more gsubrs. Yay :)
* libguile/programs.h (SCM_F_PROGRAM_IS_PRIMITIVE):
(SCM_PROGRAM_IS_PRIMITIVE): New flag and accessor.
* libguile/gsubr.c (create_gsubr):
* libguile/snarf.h (SCM_STATIC_PROGRAM): Give subrs a PRIMITIVE flag.
* libguile/smob.h:
* libguile/smob.c (scm_i_smob_arity): New internal procedure. Uses the
old GSUBR type macros, local to the file.
* libguile/procprop.c (scm_i_procedure_arity): Call out to
scm_i_smob_arity, and remove a gsubr case.
* libguile/gc.c (scm_i_tag_name):
* libguile/evalext.c (scm_self_evaluating_p):
* libguile/goops.c (scm_class_of):
* libguile/vm.c (apply_foreign):
* libguile/hash.c (scm_hasher):
* libguile/debug.c (scm_procedure_name):
* libguile/print.c (iprin1): Remove gsubr cases.
* libguile/gsubr.h (SCM_PRIMITIVE_P): Fix to work with the new VM
program regimen.
(SCM_GSUBR_TYPE, SCM_GSUBR_MAKTYPE, SCM_GSUBR_MAX, SCM_GSUBR_REQ)
(SCM_GSUBR_OPT, SCM_GSUBR_REST): Remove these macros, that are no
longer useful.
* libguile/gsubr.c (scm_i_gsubr_apply, scm_i_gsubr_apply_list)
(scm_i_gsubr_apply_array): Remove internal gsubr application
functions.
* libguile/tags.h (scm_tc7_frame, scm_tc7_objcode, scm_tc7_vm)
(scm_tc7_vm_cont): Take more tc7s for VM-related data structures.
* libguile/evalext.c (scm_self_evaluating_p):
* libguile/gc.c (scm_i_tag_name):
* libguile/goops.c (scm_class_of, create_standard_classes):
* libguile/print.c (iprin1): Add cases for the new tc7s.
* libguile/frames.c:
* libguile/frames.h:
* libguile/objcodes.c:
* libguile/objcodes.h:
* libguile/vm.c:
* libguile/vm.h: Desmobify.
* libguile/vm.c (scm_vm_apply): Export to Scheme, because VM objects are
no longer applicable.
* module/system/repl/command.scm (profile):
* module/system/vm/trace.scm (vm-trace):
* module/system/vm/vm.scm (vm-load): Call vm-apply to run a program in a
VM instead of treating the VM as applicable.
* libguile/Makefile.am (modinclude_HEADERS):
* libguile/vm-bootstrap.h: Remove vm-bootstrap.h.
* libguile/frames.c: No more vm-bootstrap.h.
* libguile/instructions.c (scm_init_instructions):
* libguile/objcodes.c (scm_init_objcodes):
* libguile/programs.c (scm_init_programs): No need to call
scm_bootstrap_vm, init.c does that for us.
* libguile/vm.c (scm_bootstrap_vm): No need call e.g.
scm_bootstrap_frames, init.c does that. Remove a twice-calling guard,
should be unnecessary. Don't define the load-compiled subr here.
* libguile/load.c (scm_init_load): Define the load-compiled subr here.
* libguile/vm.h: Declare scm_bootstrap_vm here.
* libguile/init.c (scm_i_init_guile): Properly integrate VM
bootstrapping into this file.
* libguile/vm-engine.c (VM_NAME): Keyword arg errors are now thrown to
'keyword-argument-error.
* libguile/vm.c: Define sym_keyword_argument_error, and statically
allocate some other symbols.
* module/ice-9/optargs.scm (parse-lambda-case): Throw to
'keyword-argument-error in kwarg error cases.
* module/ice-9/psyntax.scm (build-lambda-case): Remove a couple
workarounds for the old memoizer. Throw to 'wrong-number-of-args if
the lambda-case fails to parse.
* module/ice-9/psyntax-pp.scm: Regenerated.
* test-suite/tests/optargs.test: Update expected exceptions.
* libguile/vm-engine.c (VM_NAME): Engines take the VM itself (not the
vp), so they can pass the VM to hooks. No more hook args, we dispatch
without them.
* libguile/vm-engine.h (RUN_HOOK): Dispatch the hook if the trace level
is positive (instead of if the hook is there). Don't cache registers
on return from the dispatch.
* libguile/vm.h:
* libguile/vm.c (vm_dispatch_hook): Don't bother with a dynwind; instead
decrement the trace level when going into a hook, and if we have a
nonlocal exit, the trace level never gets incremented again. Worse is
better.
(make_vm, scm_vm_trace_level, scm_set_vm_trace_level_x): New concept,
trace level. If positive, we run the hooks, otherwise we don't. Should
work. Removed scm_vm_trace_frame, I don't think that was the right way
to do it.
* module/system/vm/vm.scm: Replace vm-trace-frame with vm-trace-level
and set-vm-trace-level!; the hooks actually get the frame as an
argument now.
* libguile/frames.c, libguile/objcodes.c, libguile/programs.c,
libguile/vm-engine.c, libguile/vm-i-system.c, libguile/vm.c: Use
`SCM_C_OBJCODE_BASE ()' instead of accessing the `base' field of
`struct scm_objcode'.
* libguile/objcodes.h (struct scm_objcode)[base]: Remove.
* libguile/vm.h (struct scm_vm): Remove "time" and "clock" members. The
time was bogusly measured, and the "clock" measured instructions
retired, which is not a very useful measurement, and it was causing
lots of memory accesses. Not that I have done a proper profile,
though...
(scm_vm_stats): Remove this procedure, which provided access to "time"
and "clock".
* libguile/vm.c:
* libguile/vm-engine.h:
* libguile/vm-engine.c:
* libguile/vm-i-system.c: Adapt to scm_vm changes and scm_vm_stats
removal.
* module/system/repl/command.scm:
* module/system/vm/vm.scm: Adapt to vm-stats removal by removing
vm-stats from <repl>.
