* module/system/vm/assembler.scm (system, define-f64<-f64-intrinsic):
(sqrt, abs, fsqrt, fabs):
* module/language/cps/types.scm (fsqrt, fabs): Add new f64<-f64
primitives.
These procedures were removed in Guile 2.2 by commit
fc7bd367ab (May 2011).
* libguile/socket.h (scm_inet_aton, scm_inet_ntoa): Remove.
* module/system/repl/server.scm (make-tcp-server-socket): Use
'inet-pton' instead of 'inet-aton'.
* doc/ref/web.texi (HTTP): Likewise in 'declare-header!' example.
* doc/ref/posix.texi (Network Address Conversion): Remove documentation
of 'inet-ntoa' and 'inet-aton'.
* module/language/cps/closure-conversion.scm (compute-elidable-closures):
New function.
(convert-one, convert-closures): Add ability to set "self" variable of
$kfun to $f, hopefully avoiding passing that argument in some cases.
* module/language/cps/compile-bytecode.scm (compile-function): Pass the
has-closure? bit on through to the assembler.
* module/system/vm/assembler.scm (begin-standard-arity)
(begin-opt-arity, begin-kw-arity): Only reserve space for the closure
as appropriate.
* module/language/cps/slot-allocation.scm (allocate-args)
(compute-defs-and-uses, compute-needs-slot)
(compute-var-representations): Allow for closure slot allocation
differences.
* module/language/cps/cse.scm (compute-defs):

* module/language/cps/utils.scm (compute-max-label-and-var):
* module/language/cps/verify.scm (check-distinct-vars):
(compute-available-definitions): Allow closure to be #f.
* module/system/vm/linker.scm (<linker-object>): Add name field. This
allows the linker to find sections by name, notably before having
found the .shstrtab section. As there can be multiple sections with
type SHT_STRTAB, this fixes a bug whereby we could use a section
name (a strtab index) into an unrelated strtab. In the past this
worked because with ASCII identifiers there won't be an exception,
although it is possible to accidentally mistake a shared string tail;
but with UTF-8 identifiers, it's possible for a string table index to
point in the middle of a codepoint, which is likely not valid UTF-8
and would raise a bug. Keeping an additional section name field fixes
this bug. Adapt all callers to pass a name argument to
make-linker-object.
(find-shstrndx): Update to look at the name field.
* module/system/vm/assembler.scm (make-object): Pass name to
make-linker-object.

change.

interpreter should figure it out.
(scm_bootstrap_vm): Call the new define_vm_builtins function.
* libguile/gsubr.c (primitive_call_ip): Return 0 if call IP not found.
(primitive_subr_idx): Interpret call ip == 0 as not-a-subr.

and also handle the stack manipulation.
* libguile/vm-engine.c (expand-apply-argument): Update for intrinsic
change.
(call-scm-sz-u32): Rename from call-scm-u64-u64, as it matches its
uses and will compile better on 32-bit systems.

(RUN_HOOK): Take hook name.
(APPLY_HOOK, RETURN_HOOK, NEXT_HOOK, ABORT_CONTINUATION_HOOK): Use
RUN_HOOK.
* libguile/vm.c (vm_dispatch_hook): Remove value count arg; hooks no
longer receive values (e.g. the return hook now uses
frame-return-values).
(vm_dispatch_abort_hook): Remove value count, which was bogus because
the active frame was the continuation which might contain other
locals, potentially unboxed, not the implicit return-values frame. In
the future we could push on an implicit return-values frame instead.
* module/system/vm/traps.scm (trap-in-procedure, trap-frame-finish):
(trap-in-dynamic-extent, trap-calls-to-procedure): Adapt abort hooks
to not take values. They weren't being used anyway!

when a frame is at "return-values".
(scm_init_frames_builtins): Register frame-return-values.
* libguile/vm-engine.c (RETURN_HOOK): Rename from POP_CONTINUATION_HOOK.
(call, call-label): Remove PUSH_CONTINUATION_HOOK; it's unneeded, as
you can always check the FP from an apply hook.
(return-values): Run return hook before popping frame.
* libguile/vm.c (vm_dispatch_return_hook): Rename from
vm_dispatch_pop_continuation_hook. Remove push continuation hook.
(scm_vm_return_hook):

code as the key, even for primitives.
* libguile/gsubr.c: Reimplement to store subr names and procedures in a
side table, and to allocate fresh vcode for each subr. This allows
JIT of subrs, moves to a uniform all-code-starts-with-instrument-entry
regime, and also allows statprof to distinguish between subrs based on
IP.
* libguile/gsubr.h (SCM_SUBRF, SCM_SUBR_NAME): Call out to functions,
now that these are in a side table.

samples and call counts.

(frame-instruction-pointer-or-primitive-procedure-name): Removed.
* libguile/programs.h:
* libguile/programs.c (scm_primitive_code_name): New function.
* module/system/vm/program.scm (primitive-code-name): New export.
* module/system/vm/assembler.scm (<jit-data>, <meta>): Rework to have
<meta> create the <jit-data> in the end-program, so that jit-data
isn't mutable. Record start and end PC values relative to '.rtl-text
so that we don't need any more linker symbols.
(emit-instrument-entry*, emit-instrument-loop*, begin-program):
(end-program): Adapt.
(begin-kw-arity): Include the initial instrument-entry in the first
arity.
(link-data, link-constants): Write the init routine before interning

routine.

* module/language/cps/loop-instrumentation.scm: Rename from
handle-interrupts.scm and just add "instrument-loop" primcalls in
loops. The compiler will add handle-interrupts primcalls as
appropriate.
* module/system/vm/assembler.scm (<jit-data>): New data type, for
emitting embedded JIT data.
(<meta>): Add field for current JIT data.
(make-meta): Initialize current JIT data.

emitters that reference the current JIT data.
(end-program): Now that all labels are known, arrange to serialize the
JIT data.

the "start" / "end" fields.
* libguile/jit.h (struct scm_jit_function_data)
(enum scm_jit_counter_value): New data types.

* libguile/vm.c (vm_dispatch_pop_continuation_hook):
(vm_dispatch_abort_hook): Adapt for where to expect values.
(vm_builtin_values_code): Add a call to shuffle-down before
returning. This is more overhead than what existed before, but the
hope is that the savings elsewhere pay off.

(reinstate_continuation_x, compose_continuation): Adapt to place
resume args at right position.
