* libguile/expand.c (convert_assignment): Handle creation of the default
lambda-case body here.
* libguile/eval.c (eval):
* module/ice-9/eval.scm (primitive-eval):
* libguile/memoize.h:
* libguile/memoize.c (MAKMEMO_BOX_REF, MAKMEMO_BOX_SET):
(MAKMEMO_TOP_BOX, MAKMEMO_MOD_BOX): Refactor all global var resolution
to go through "resolve". Add "box-ref" and "box-set!". Rename
memoize-variable-access! to %resolve-variable, and don't be
destructive.
* libguile/memoize.c (FULL_ARITY): Serialize "ninits" and the unbound
value instead of the init list.
(memoize): Adapt to FULL_ARITY changes. Remove LETREC case.
(unmemoize): Adapt to memoized code change.
* libguile/eval.c (BOOT_CLOSURE_PARSE_FULL): Adapt to parse ninits and
unbound instead of inits.
(eval): Lexical-ref can no longer raise an error.
(prepare_boot_closure_env_for_apply): Adapt to inits change.
* module/ice-9/eval.scm (primitive-eval): Adapt to ninits/unbound
change.
* libguile/expand.c (expand_named_let): Fix lambda-case creation to make
lists for opt and inits.
* libguile/gc.c (scm_oom_fn, scm_init_gc): Install an out-of-memory
handler that raises an unwind-only out-of-memory exception.
(scm_gc_warn_proc, scm_init_gc): Install a warning proc that tries to
print to the current warning port, if the current warning port is a
file port.
(scm_gc_after_nonlocal_exit): New interface. Should be called after a
nonlocal return to potentially collect memory; otherwise allocations
could try to expand again when they should collect.
* libguile/continuations.c (scm_i_make_continuation):
* libguile/eval.c (eval):
* libguile/throw.c (catch):
* libguile/vm.c (scm_call_n): Call scm_gc_after_nonlocal_exit after
nonlocal returns.
* libguile/throw.c (abort_to_prompt, throw_without_pre_unwind): Rework
to avoid allocating memory.
(scm_report_out_of_memory): New interface.

realloc fails.
* libguile/error.h:
* libguile/error.c:
* libguile/deprecated.h:
* libguile/deprecated.c (scm_memory_error): Deprecate.
* test-suite/standalone/Makefile.am:
* test-suite/standalone/test-out-of-memory: New test case.
* libguile/vm.c (scm_i_capture_current_stack): Cosmetic tweak.
(scm_call_n): Define here instead of in eval.c. All callers of
scm_c_vm_run were passing scm_the_vm() as the VM. Eventually
scm_call_n will replace scm_c_vm_run.
* libguile/eval.c: Adapt all callers.
* libguile/control.h:
* libguile/control.c (scm_i_prompt_pop_abort_args_x): Change to take VP
as an arg, not VM.
* libguile/eval.c (eval):
* libguile/throw.c (pre_init_catch): Adapt.
* libguile/dynstack.h:
* libguile/dynstack.c (PROMPT_FP, PROMPT_SP):
(scm_dynstack_push_prompt, scm_dynstack_find_prompt): Prompts on the
dynstack are recorded as offsets from the base stack address in this
thread.
* libguile/control.c (scm_c_abort):
* libguile/eval.c (eval):
* libguile/stacks.c (find_prompt, narrow_stack):
* libguile/throw.c (pre_init_catch):
* libguile/vm-engine.c (prompt): Adapt.
* libguile/eval.c (scm_apply_0, scm_apply_1, scm_apply_2, scm_apply_3)
(scm_map, scm_for_each, scm_apply): Change to prefer scm_apply_0, and
to have it call vm_run instead of call_with_vm.
(eval): Use scm_apply_0 and scm_call_0.
* libguile/srfi-1.c (scm_srfi1_count): Use scm_apply_0.
* libguile/memoize.h (SCM_M_CAPTURE_MODULE)
* libguile/memoize.c (MAKMEMO_CAPTURE_MODULE, capture_env):
(maybe_makmemo_capture_module, memoize): Determine when to capture the
module on the environment chain at compile-time, instead of at
runtime. Introduces a new memoized expression type, capture-module.
(scm_memoized_expression): Start memoizing with #f as the
environment.
(unmemoize): Add unmemoizer.
(scm_memoize_variable_access_x): Cope with #f as module, and treat as
the root module (captured before modules were booted).
* libguile/eval.c (eval):
* module/ice-9/eval.scm (primitive-eval): Adapt.
* libguile/memoize.c (MAKMEMO): Memoized objects are pairs now, not
SMOBs. This lets eval.scm destructure them more efficiently.
(scm_print_memoized, scm_memoized_p, scm_memoized_expression_typecode)
(scm_memoized_expression_data): Remove these interfaces.
(unmemoize, scm_memoize_variable_access_x): Remove SMOB type checks.
(scm_init_memoize): Remove SMOB type definition.
* libguile/memoize.h (scm_tc16_memoized, SCM_MEMOIZED_P)
(scm_memoized_expression_typecode, scm_memoized_expression_data)
(scm_memoized_p): Remove declarations.
* libguile/validate.h (SCM_VALIDATE_MEMOIZED): Remove declaration.
* libguile/eval.c (eval): Remove memoized type check, and inline the
inum unpacking.
* module/ice-9/eval.scm (memoized-expression-case): Use car and cdr to
destructure memoized expressions. A big win!
* libguile/memoize.c (MAKMEMO_LEX_REF, MAKMEMO_LEX_SET): Change to
address lexicals by depth and width.
(try_lookup_rib, lookup_rib, make_pos): New helpers.
(lookup): Adapt to return a pair.
(memoize, unmemoize_bindings, unmemoize_lexical): Adapt.
* libguile/eval.c (eval, prepare_boot_closure_env_for_eval):
(prepare_boot_closure_env_for_apply):
* module/ice-9/eval.scm (make-fixed-closure, make-general-closure)
(eval): Adapt to new environment.
This is currently a slight win for C, and a slight lose for Scheme --
because the lookup loop is so poorly compiled by the stack VM. I expect
that the RTL-compiled eval will fix this.
* libguile/dynstack.h (scm_t_dynstack_prompt_flags): New flag,
SCM_F_DYNSTACK_PROMPT_PUSH_NARGS, set if the continuation expects the
number of args to be pushed on the top of the stack.
* libguile/control.c (scm_c_abort): Only push nargs if requested.
* libguile/eval.c (eval):
* libguile/throw.c (pre_init_catch):
* libguile/vm-i-system.c (prompt): Set
SCM_F_DYNSTACK_PROMPT_PUSH_NARGS.
* libguile/vm-i-system.c (push-fluid, pop-fluid):
* doc/ref/vm.texi (Dynamic Environment Instructions): Rename wind-fluids
to push-fluid, and unwind-fluids to pop-fluid. They now only work on
one fluid binding at a time.
* module/ice-9/boot-9.scm (with-fluid*): Implement in Scheme in terms of
primcalls to push-fluid and pop-fluid.
(custom-throw-handler, catch, with-throw-handler): Use with-fluid*
instead of with-fluids, as with-fluids is no longer available before
psyntax is loaded.
(with-fluids): Define in Scheme in terms of with-fluid*.
* libguile/fluids.c (scm_with_fluid): Rename from scm_with_fluids, and
don't expose to Scheme.
* libguile/eval.c (eval): Remove SCM_M_WITH_FLUIDS case.
* libguile/expand.c (expand_with_fluids): Remove with-fluids syntax.
(DYNLET): Remove, no longer defining dynlet in the %expanded-vtables.
* libguile/expand.h: Remove dynlet definitions.
* module/ice-9/eval.scm (primitive-eval): Remove with-fluids case.
* libguile/memoize.c (do_push_fluid, do_pop_fluid): New primitive
helpers, like wind and unwind.
(memoize): Memoize wind and unwind primcalls. Don't memoize dynlet to
with-fluids.
(scm_init_memoize): Initialize push_fluid and pop_fluid here.
* libguile/memoize.h (SCM_M_WITH_FLUIDS): Remove definition.
* module/ice-9/psyntax.scm (build-dynlet): Remove; this just supported
with-fluids, which is now defined in boot-9.
* module/ice-9/psyntax-pp.scm: Regenerate.
* doc/ref/compiler.texi (Tree-IL):
* module/language/tree-il.scm:
* module/language/tree-il/analyze.scm:
* module/language/tree-il/canonicalize.scm:
* module/language/tree-il/compile-glil.scm:
* module/language/tree-il/cse.scm:
* module/language/tree-il/debug.scm:
* module/language/tree-il/effects.scm: Remove <dynlet>. Add cases for
primcalls to push-fluid and pop-fluid in compile-glil.scm and
effects.scm.
* module/language/tree-il/peval.scm (peval): Factor out
with-temporaries; probably a bad idea, but works for now. Factor out
make-begin0 (a better idea). Inline primcalls to with-fluid*, and
remove dynlet cases.
* module/language/tree-il/primitives.scm (*interesting-primitive-names*):
Add with-fluid*.
* doc/ref/compiler.texi: Remove mention of <dynwind>.
* libguile/eval.c (eval): Remove SCM_M_DYNWIND case.
* libguile/expand.c: Remove scm_sym_at_dynamic_wind.
* libguile/memoize.c (do_wind, do_unwind): A couple of hacky subrs. If
we see a wind or unwind primcall, we expand to a call of a quoted subr
value. It works and removes a kind of memoized value from the
interpreter. For the compiler,primcalls to wind and unwind are
handled specially.
(MAKMEMO_DYNWIND): Remove.
(scm_tc16_memoizer): Remove. Yay!
(memoize): Remove speculative lookup for toplevels to see if they are
memoizers: there are no more memoizers. Memoize calls to the wind and
unwind primitives.
(m_dynamic_wind): Remove.
(unmemoize): Remove dynwind case.
(scm_init_memoize): Add wind and unwind local definitions.
* module/ice-9/boot-9.scm (dynamic-wind): Reimplement in terms of "wind"
and "unwind" primitives. These primitives are not exposed to other
modules.
* module/ice-9/eval.scm (primitive-eval): Remove dynwind case.
* module/language/scheme/decompile-tree-il.scm (do-decompile):
(choose-output-names): Remove dynwind cases.

* module/language/tree-il/analyze.scm (analyze-lexicals): Remove dynwind
cases.
* module/language/tree-il/compile-glil.scm (*primcall-ops*): Add wind
and unwind.
(flatten-lambda-case): Remove dynwind case. Yay!
* module/language/tree-il/cse.scm (cse):
* module/language/tree-il/debug.scm (verify-tree-il):
* module/language/tree-il/effects.scm (make-effects-analyzer):
* module/language/tree-il/peval.scm (singly-valued-expression?, peval):
Remove <dywind> cases. Inline primcalls to dynamic-wind. Add
constant folding for thunk?.
* module/language/tree-il/primitives.scm (*interesting-primitive-names*):
Remove @dynamic-wind, and add procedure? and thunk?.
(*effect+exception-free-primitives*): Add procedure? and thunk?.
(*multiply-valued-primitives*): Remove @dynamic-wind.
Remove @dynamic-wind expander.
* test-suite/tests/peval.test ("partial evaluation"): Update tests for
dynwind desugaring.
* libguile/memoize.h:
* libguile/memoize.c (MAKMEMO_CALL_WITH_PROMPT, memoize, unmemoize):
Remove the @prompt memoizer in favor of recognizing call-with-prompt
primcalls. Rename SCM_M_PROMPT to SCM_M_CALL_WITH_PROMPT, and pass a
thunk instead of an expression so that it has normal applicative
order.
* libguile/expand.c (PRIMITIVE_REF, PRIMCALL, expand): Produce primcalls
from forms whose car is a primitive.
(expand_atat): Recognize (@@ primitive FOO) as being a primitive-ref.
* module/ice-9/boot-9.scm (call-with-prompt): Instead of dispatching to
the wonky @prompt memoizer, residualize a primcall to
call-with-prompt. The memoizer will DTRT to allow call-with-prompt to
be interpreted correctly without needing an additional binding.
* module/ice-9/eval.scm (primitive-eval): Change the 'prompt clause to a
call to call-with-prompt.
* module/language/tree-il/primitives.scm: No more need to recognize
@prompt.
* libguile/eval.c (eval): Adapt to SCM_M_PROMPT renaming to
SCM_M_CALL_WITH_PROMPT, and apply the thunk.
* libguile/throw.c (pre_init_throw): Adapt to scm_abort_to_prompt_star
rename.
* libguile/vm.c (vm_error_kwargs_invalid_keyword,
vm_error_kwargs_unrecognized_keyword): Add parameter. Pass it
enclosed in a list as the last argument to `scm_error_scm'.
* libguile/vm-i-system.c (bind_kwargs): Adjust accordingly.
* libguile/eval.c (error_invalid_keyword, error_unrecognized_keyword):
Add parameter.
(prepare_boot_closure_env_for_apply): Adjust accordingly.
* module/ice-9/eval.scm (primitive-eval): Likewise.

docstring.
* module/ice-9/boot-9.scm (keyword-error-printer): New procedure; use it.
* test-suite/tests/optargs.test (c&e, with-test-prefix/c&e): Remove.
("define*")["unrecognized keyword"]: Test the value passed along the
`keyword-argument-error' exception.
["invalid keyword"]: New test.
* doc/ref/api-control.texi (Error Reporting): Update `scm-error'
description.
* doc/ref/api-procedures.texi (Case-lambda): Expand case-lambda*
documentation.
* module/ice-9/eval.scm (primitive-eval):
* libguile/eval.c (prepare_boot_closure_env_for_apply): Dispatch to the
next case-lambda clause if there are too many positionals.
* doc/ref/vm.texi (Function Prologue Instructions):
* libguile/vm-i-system.c (bind-optionals/shuffle-or-br): New
instruction, like bind-optionals/shuffle but can dispatch to the next
clause if there are too many positionals.
* module/language/assembly/disassemble.scm (code-annotation):
* module/language/assembly/decompile-bytecode.scm (decode-load-program):
* module/language/assembly/compile-bytecode.scm (compile-bytecode): Add
case for bind-optionals/shuffle-or-br.
* module/language/glil/compile-assembly.scm (glil->assembly): If there
is an alternate, use bind-optionals/shuffle-or-br instead of
bind-optionals/shuffle.
* test-suite/tests/optargs.test ("case-lambda*"): Add tests.
Fixes <http://bugs.gnu.org/12173>.
Reported by Ian Price <ianprice90@googlemail.com>.
* libguile/memoize.c (MAKMEMO_LAMBDA): New `docstring' parameter. Add
it as the second argument of `SCM_M_LAMBDA'. Update caller.
(memoize)[SCM_M_LAMBDA]: Extract docstring from EXP; when `memoize'
returns, add the docstring to the lambda's arguments.
(unmemoize)[SCM_M_LAMBDA]: Adjust to new argument layout of
`SCM_M_LAMBDA'.
* libguile/eval.c (BOOT_CLOSURE_NUM_REQUIRED_ARGS,
BOOT_CLOSURE_HAS_REST_ARGS, BOOT_CLOSURE_IS_REST,
BOOT_CLOSURE_PARSE_FULL): Adjust to new argument layout of
`SCM_M_LAMBDA'.
* module/ice-9/eval.scm (primitive-eval)[make-general-closure]:
Likewise.
[eval]: When EXP is a lambda, match its docstring; when the docstring
is not #f, add it to the closures procedure properties.
* test-suite/tests/eval.test ("docstrings"): New test prefix.
* libguile/procs.c (sym_documentation): Rename to...
(scm_sym_documentation): ... this. Make it global.
* libguile/procs.h (scm_sym_documentation): New declaration.
* libguile/control.h: Remove scm_t_prompt_registers and
scm_c_make_prompt_registers.
(scm_c_abort): Take a pointer to a jmpbuf instead of a cookie. It
will serve the same purpose.
* libguile/control.c (reify_partial_continuation, scm_at_abort): Adapt
to new prompt representation.
* libguile/dynstack.h:
* libguile/dynstack.c (scm_dynstack_push_prompt): Prompts now have 5
words instead of 2, as they now push the fp, sp, ip, and jmpbuf on the
stack separately. This avoids allocation.
(scm_dynstack_find_prompt): Likewise, add return values for fp, sp,
etc.
(scm_dynstack_wind_prompt): Replaces scm_dynstack_relocate_prompt.
* libguile/eval.c (eval):
* libguile/stacks.c (find_prompt):
* libguile/throw.c (pre_init_catch): Adapt to the new prompt mechanism.
* libguile/vm-engine.c (vm_engine): Setjmp an on-stack jmpbuf every time
the VM enters. We can then re-use that jmpbuf for all prompts in that
invocation.
* libguile/vm-i-system.c (partial_cont_call): Adapt to change in prompt
representation. We don't need to wind here any more, since we pass in
the prompt's jmpbuf.
(prompt): Adapt to scm_dynstack_push_prompt change.
(abort): Adapt to vm_abort change.
* libguile/vm.h (struct scm_vm): No more cookie.
* libguile/vm.c (vm_abort): Adapt to scm_c_abort change.
(vm_reinstate_partial_continuation): Rewind the dynamic stack here,
now that we do have a valid jmpbuf.
(make_vm): No need to initialize a cookie.
* libguile/dynstack.h:
* libguile/dynstack.c: New files, implementing the dynamic stack as a
true stack instead of a linked list. This lowers the cost of
dynwinds: frames, winders, prompts, with-fluids, and dynamic-wind.
For the most part, we allocate these items directly on the stack.
* libguile/dynwinds.h:
* libguile/dynwinds.c: Adapt all manipulators of the wind stack to use
interfaces from dynstack.c. Remove heap-allocated winder and frame
object types.
(scm_dowinds, scm_i_dowinds): Remove these. The first was exported,
but it was not a public interface.
* libguile/continuations.c:
* libguile/continuations.h (scm_t_contregs): Continuation objects
reference scm_t_dynstack* values now. Adapt to the new interfaces.
* libguile/control.c:
* libguile/control.h: There is no longer a scm_tc7_prompt kind of object
that can be allocated on the heap. Instead, the prompt flags, key,
and registers are pushed on the dynwind stack. (The registers are
still on the heap.) Also, since the vm_cont will reference the
dynwinds, make the partial continuation stub take just one extra arg,
instead of storing the intwinds separately in the object table.
* libguile/fluids.c:
* libguile/fluids.h: No more with-fluids objects; instead, the fluids go
on the dynstack. The values still have to be on the heap, though.
(scm_prepare_fluids, scm_swap_fluids): New internal functions,
replacing scm_i_make_with_fluids and scm_i_swap_with_fluids.
* libguile/print.c: Remove prompt and with-fluids printers.
* libguile/tags.h: Revert prompt and with-fluids tc7 values to what they
were before they were allocated.
* libguile/vm-i-system.c (partial_cont_call): Just pop the vmcont, the
intwinds will not be passed as a second arg. Rewind the dynamic stack
from within the VM, so that any rewinder sees valid prompt entries.
(call_cc, tail_call_cc): Adapt to pass the dynstack to
scm_i_vm_capture_stack.
(prompt, wind, unwind, wind_fluids, unwind_fluids): Adapt to the new
interfaces.
* libguile/vm.h (scm_i_capture_current_stack): Rename from
scm_i_vm_capture_continuation.
(scm_i_vm_capture_stack): Take a dynstack as an argument.
* libguile/vm.c (vm_reinstate_partial_continuation): Don't wind here, as
that could result in winders seeing invalid prompts.
* libguile/eval.c:
* libguile/root.c:
* libguile/stacks.c:
* libguile/threads.c:
* libguile/threads.h:
* libguile/throw.c: Adapt other users of dynwinds to use the dynstack.
* libguile/ports.c (scm_putc, scm_puts):
* libguile/ports.h (scm_putc_unlocked, scm_puts_unlocked): Separate into
_unlocked and locked variants. Change all callers to use the
_unlocked versions.
* libguile/expand.h:
* module/language/tree-il.scm: Rename "sequence" to "seq", and instead
of taking a list of expressions, take a head and a tail.
* module/language/tree-il/analyze.scm:
* module/language/tree-il/compile-glil.scm:
* module/language/tree-il/fix-letrec.scm:

* module/ice-9/eval.scm:
* libguile/memoize.h:
* libguile/memoize.c:
* libguile/expand.c:
* libguile/eval.c: Adapt to the new seq format.
* module/ice-9/boot-9.scm (map, for-each): Implement in Scheme instead
of C. There are boot versions before `cond' is defined.
(map-in-order): Define this alias here instead of in evalext.h.
* libguile/eval.c: Stub out the map and for-each definitions to just
call into Scheme.
* libguile/evalext.c: Remove map-in-order definition.
* module/srfi/srfi-1.scm: Replace all calls to map1 with calls to map.
(map, for-each): Define implementations here, in Scheme, instead of in
C.
* test-suite/tests/eval.test (exception:wrong-length, "map"): Update the
expected exception for mapping over lists of different lengths.
* libguile/srfi-1.h:
* libguile/srfi-1.c: Remove map and for-each definitions. Remove the
bit that extended the core `map' primitive with another method: the
right way to do that is with modules.
* libguile/eval.c (truncate_values): New helper.
(EVAL1): New macro, does an eval then truncates the values.
(eval, prepare_boot_closure_env_for_apply)
(prepare_boot_closure_env_for_eval): Use EVAL1 in appropriate places
to get multiple-values truncation even here in the boot evaluator.
eval.c fixen
* libguile/control.h:
* libguile/control.c (scm_i_prompt_pop_abort_args_x): Take a VM instead
of a prompt, given that it's the VM's registers that record the abort
arguments, not the prompt registers (which actually point right below
the abort values).
* libguile/eval.c (eval):
* libguile/throw.c (pre_init_catch): Pass the vm instead of a prompt.
* libguile/bytevectors.c:
* libguile/eval.c:

* 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:

fit a pointer into a long.
* libguile/eval.c:
* libguile/debug.c (scm_debug_opts): Move here, from eval.c. Change
SCM_BACKTRACE_P to 1, initially.
* libguile/private-options.h: Make all options vars private.
* 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/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/eval.c: Mark "breakpoints", "trace", and "procnames" debug
options as obsolete. There is lots of work left to do here, though.
* libguile/srcprop.h (scm_sym_breakpoint)
(scm_c_source_property_breakpoint_p, SRCBRKP): Remove these
definitions, without replacements.
* libguile/srcprop.c: Remove all code that has to do with breakpoints.
