* guile-tools.in: Fix the checks to account for non-srcdir builds.
* libguile/frames.c:
* libguile/objcodes.c:
* libguile/programs.c:
* libguile/instructions.c:
* libguile/vm.c: Fix snarf-includes to cope with non-srcdir builds.
* libguile/instructions.h:
* libguile/instructions.c: Fix the stubs inclusion to be non-srcdir
compatible.
* libguile/vm-expand.h (VM_DEFINE_INSTRUCTION): Fix some things so as not
to require the instructions.h defintitions, since we have the codes
already. Not important tho :)
* pre-inst-guile-env.in: Minor tweak that should have no effect.
* test-suite/standalone/Makefile.am (all-local): Remove a chmod +x step,
the configure.ac rule should do that if necessary.
The idea is to introduce `gsubrs' whose arity is encoded in their type
(more precisely in the sizeof (void *) - 8 MSBs). This removes the
indirection introduced by cclos and simplifies the code.
* libguile/__scm.h (CCLO): Remove.
* libguile/debug.c (scm_procedure_source, scm_procedure_environment):
Remove references to `scm_tc7_cclo'.
* libguile/eval.c (scm_trampoline_0, scm_trampoline_1,
scm_trampoline_2): Replace `scm_tc7_cclo' with `scm_tc7_gsubr'.
* libguile/eval.i.c (CEVAL): Likewise. No longer make PROC the first
argument. Directly invoke `scm_gsubr_apply ()' instead of jump to the
`evap(N+1)' label or call to `SCM_APPLY ()'.
* libguile/evalext.c (scm_self_evaluating_p): Remove reference to
`scm_tc7_cclo'.
* libguile/gc-card.c (scm_i_sweep_card, scm_i_tag_name): Likewise.
* libguile/gc-mark.c (scm_gc_mark_dependencies): Likewise.
* libguile/goops.c (scm_class_of): Likewise.
* libguile/print.c (iprin1): Likewise.
* libguile/gsubr.c (create_gsubr): Use `unsigned int's for REQ, OPT and
RST. Use `scm_tc7_gsubr' instead of `scm_makcclo ()' in the default
case.
(scm_gsubr_apply): Remove calls to `SCM_GSUBR_PROC ()'.
(scm_f_gsubr_apply): Remove.
* libguile/gsubr.h (SCM_GSUBR_TYPE): New definition.
(SCM_GSUBR_MAX): Changed to 33.
(SCM_SET_GSUBR_TYPE, SCM_GSUBR_PROC, SCM_SET_GSUBR_PROC,
scm_f_gsubr_apply): Remove.
* libguile/procprop.c (scm_i_procedure_arity): Remove reference to
`scm_tc7_cclo'; add proper handling of `scm_tc7_gsubr'.
* libguile/procs.c (scm_makcclo, scm_make_cclo): Remove.
(scm_procedure_p): Remove reference to `scm_tc7_cclo'.
(scm_thunk_p): Likewise, plus add proper `scm_tc7_gsubr' handling.
* libguile/procs.h (SCM_CCLO_LENGTH, SCM_MAKE_CCLO_TAG,
SCM_SET_CCLO_LENGTH, SCM_CCLO_BASE, SCM_SET_CCLO_BASE, SCM_CCLO_REF,
SCM_CCLO_SET, SCM_CCLO_SUBR, SCM_SET_CCLO_SUBR, scm_makcclo,
scm_make_cclo): Remove.
* libguile/stacks.c (read_frames): Remove reference to `scm_f_gsubr_apply'.
* libguile/tags.h (scm_tc7_cclo): Remove.
(scm_tc7_gsubr): New.
(scm_tcs_subrs): Add `scm_tc7_gsubr'.
* libguile/stacks.c (scm_make_stack): Instead of aborting when we misread
the number of stack frames, just print a warning. I'd like to figure
out what these cases are, exactly.
* module/language/scheme/compile-ghil.scm (lambda): Reindent the lambda
transformer.
* module/system/base/compile.scm (call-with-compile-error-catch): Write
the expression instead of displaying it.
(call-with-output-file/atomic): Don't actually redirect output to this
port, as it's not necessary -- the language-printer should respect the
port that we pass.
* libguile/frames.c (vm_frame_print): Add a frame printer.
* libguile/stacks.c (stack_depth, read_frames): Only switch the VM stack
for boot program dframes.
* libguile/vm-engine.c (VM_NAME): Push one debug frame per invocation,
unconditionally. (If we push them at all, of course.)
* libguile/programs.h (SCM_F_PROGRAM_IS_BOOT, SCM_PROGRAM_IS_BOOT): Flags
for determining if a program is a boot program. It turns out that our
heuristics e.g. in stacks.c would catch non-boot programs, like
programs that end with (goto/args 1), because the 1 is the same byte as
`halt'. That took a while to find...
* libguile/stacks.c (stack_depth, read_frames): Use the new boot prog
macros.
(scm_make_stack): Assert that we read the number of frames that we said
we would.
* libguile/vm.c (really_make_boot_program): Mark boot programs
appropriately.
* 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.
* libguile/vm.h (struct scm_vm_cont):
* libguile/vm.c (capture_vm_cont, reinstate_vm_cont): Change so we just
store the registers as they are, with the reloc.
(vm_cont_mark): Only mark the stack if it has elements on it, otherwise
we get a bogus fp.
* libguile/stacks.c (scm_make_stack): Update for change to vm
continuations.
* 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.
SCM_INUM): Deprecated by reenaming them to SCM_I_INUMP, SCM_I_NINUMP
and SCM_I_INUM, respectively and adding deprecated versions to
deprecated.h and deprecated.c. Changed all uses to either use the
SCM_I_ variants or scm_is_*, scm_to_*, or scm_from_*, as appropriate.
SCM_VALIDATE_BIGINT, SCM_VALIDATE_INUM_MIN,
SCM_VALIDATE_INUM_MIN_COPY,
SCM_VALIDATE_INUM_MIN_DEF_COPY,SCM_VALIDATE_INUM_DEF,
SCM_VALIDATE_INUM_DEF_COPY, SCM_VALIDATE_INUM_RANGE,
SCM_VALIDATE_INUM_RANGE_COPY): Deprecated because they make the
fixnum/bignum distinction visible. Changed all uses to scm_to_size_t
or similar.
SCM_NEGATE_BOOL, SCM_BOOLP): Deprecated by moving into "deprecated.h".
Replaced all uses with scm_is_false, scm_is_true, scm_from_bool, and
scm_is_bool, respectively.
* *.c: add space after commas everywhere.
* *.c: use SCM_VECTOR_SET everywhere, where a vector is written.
Document cases where SCM_WRITABLE_VELTS() is used.
* vectors.h (SCM_VELTS): prepare for write barrier, and let
SCM_VELTS() return a const pointer
(SCM_VECTOR_SET): add macro.
* autogen.sh (mscripts): find and check version number of
autoconf. Complain if 2.53 is not found.

the new and shiny SCM_NUM2INT.
* extensions.c: extension -> extension_t (and made a typedef).

there are no nasty surprises if/when the various deeply magic tag
bits move somewhere else.
* eval.c: changed the locals used to store results of SCM_IFRAME,
scm_ilength and such to be of type scm_bits_t (and not int/long).

exist (for size_t & ptrdiff_t)
(scm_sizet): deprecated.

custom tc7 type. This will make it easier to support R5RS

continuation_free, continuation_print, continuation_apply):
new SMOB support.

(CHEAP_CONTINUATIONS): removed non-working code completely.
