Fixes <https://bugs.gnu.org/31606>
Reported by Tommi Höynälänmaa <tommi.hoynalanmaa@gmail.com>
* module/oop/goops.scm (instance?): Check that OBJ is a struct
before applying 'struct-vtable' to it.
Fixes <https://bugs.gnu.org/31474> and related bugs.
Reported by Jan Nieuwenhuizen <janneke@gnu.org>.
* module/language/cps/types.scm (next-power-of-two): Remove procedure.
(non-negative?, lognot*, saturate+, saturate-, logand-bounds)
(logsub-bounds, logior-bounds, logxor-bounds): New procedures. Use them
to improve and fix bugs in the range analysis of the type inferrers for
'logand', 'logsub', 'logior', 'ulogior', 'logxor', 'ulogxor', and
'lognot'.
Fixes <https://bugs.gnu.org/29520>.
Reported by Stefan Israelsson Tampe <stefan.itampe@gmail.com>.
* module/language/tree-il/peval.scm (peval)[lift-applied-lambda]: Before
performing eta-conversion, check that the variable(s) passed to the
inner 'apply' are not referenced from the inner lambda, and that the
number of required arguments would not be reduced by the conversion.
* module/system/base/target.scm (cpu-endianness): Add case for "riscv" variants.

This is a followup to <https://bugs.gnu.org/29704>.
* module/srfi/srfi-18.scm (thread-sleep!): When TIMEOUT is a number,
keep it as-is.
* test-suite/tests/srfi-18.test ("thread sleep with number"): Pass 0 as
the timeout.
("thread sleeps fractions of a second"): Pass 0.5 as the timeout.
Fixes <https://bugs.gnu.org/29704>.
Reported by David Beswick <dlbeswick@gmail.com>.
* module/srfi/srfi-18.scm (timeout->absolute-time): New procedure.
(mutex-lock!): Use it in 'thread:lock-mutex' call.
(mutex-unlock!): Use it.
* test-suite/tests/srfi-18.test ("mutex-lock! returns false on timeout")
("mutex-lock! returns true when lock obtained within timeout")
("recursive lock waits")
("mutex unlock is false when condition times out"): Adjust cases where
the 'timeout' parameter is a number so that it's a relative number.
Fixes a bug whereby "guild compile --target=arm-linux-gnueabihf
--from=elisp ... language/elisp/boot.el" would fail with an exception
from 'load-thunk-from-memory' while trying to load (language elisp spec)
from the guile-being-compiled instead of using that of the
guile-for-build.
The problem did not manifest with --from=scheme because (language scheme
spec) happened to be already loaded before we had changed %load-path.
* module/scripts/compile.scm (compile): Add calls to 'lookup-language'.
* libguile/vm-engine.c (RUN_HOOK0, RUN_HOOK1): Remove.
(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):
* libguile/vm.h (SCM_VM_PUSH_CONTINUATION_HOOK): Remove.
(SCM_VM_RETURN_HOOK): Rename from SCM_VM_POP_CONTINUATION_HOOK.

arguments.

Adapt to return hook coming from returning frame.

return hook.

handle in the future.
* module/statprof.scm (statprof-proc-call-data): Always use the program
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.
(scm_subr_function, scm_subr_name): New exports.

samples and call counts.
* module/system/vm/frame.scm (frame-procedure-name): Simplify.
(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
constants so that we correctly emit the jit-data for the init
routine.
* libguile/programs.c (try_parse_arity): Skip over a
scm_op_instrument_entry, if any.
* am/bootstrap.am (SOURCES):
* module/Makefile.am (SOURCES): Handle renamve of handle-interrupts.scm

handle-interrupts code before calls and returns. Compile the
"instrument-loop" primcall to an "instrument-loop" instruction and a
"handle-interrupts" instruction.
(lower-cps): Adapt to add-loop-instrumentation name change.
* 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.
(emit-instrument-entry*, emit-instrument-loop*): New instruction
emitters that reference the current JIT data.
(end-program): Now that all labels are known, arrange to serialize the
JIT data.
(link-data): Reserve space for JIT data, and add relocs to initialize
the "start" / "end" fields.
* libguile/jit.h (struct scm_jit_function_data)
(enum scm_jit_counter_value): New data types.
* libguile/jit.c (scm_jit_compute_mcode, scm_jit_enter_mcode): New

instructions.

resume args at right position.
(capture_delimited_continuation): Remove unused sp and ip arguments.

(scm_call_n): Adapt to not reserve space for the boot closure.
* module/language/cps/compile-bytecode.scm (compile-function): When
returning values, adapt reset-frame call for return calling convention
change. Adapt truncating or rest returns to expect values in the
right place.
* module/language/cps/slot-allocation.scm (compute-shuffles):
(allocate-lazy-vars, allocate-slots): Allocate values from the "proc
slot", not proc-slot + 1.

SCM_FRAME_RETURN_ADDRESS and SCM_FRAME_SET_RETURN_ADDRESS.

size as a parameter.
