* libguile/macros.c (scm_i_make_primitive_macro): Give primitive macros
a primitive-macro macro-type.
* module/ice-9/psyntax.scm (put-global-definition-hook)

Fixes #27476, a horrible race when one thread is expanding a
syntax-parameterize form including uses, and another thread is expanding
the corresponding define-syntax-parameter. See

Partially fixes <https://bugs.gnu.org/33044>.
Reported by Tom de Vries <tdevries@suse.de>.
* libguile/random.c (scm_seed_to_random_state): Use 'scm_to_utf8_string'
(or 'scm_to_latin1_string' for a narrow string, for compatibility) to
convert the string into raw bytes for use by 'scm_c_make_rstate'. Make
sure the length in bytes fits within an 'int'.
|
|
* libguile/strings.h: In a comment, add the missing "i_" in
"scm_i_is_narrow_string".

Partial fix for <https://bugs.gnu.org/33044>.
Reported by Tom de Vries <tdevries@suse.de>.
Fix several instances of the mistake of using 'scm_from_locale_*' for C
strings that originally came from a C string literal. Change several
uses of 'scm_from_latin1_*' as well, to promote the practice of writing
code that works for arbitrary C string literals.
Also add missing years to the copyright notices of changed files, based
on the git history.

Fixes <https://bugs.gnu.org/21901>.
Reported by Zefram <zefram@fysh.org>.
* libguile/numbers.c: Add another top-level 'verify' to ensure that
LONG_MIN is not a fixnum.
(scm_ash, scm_round_ash): Ensure that when the shift count is LONG_MIN,
it is not handled via the normal code path, to avoid signed overflow
when the shift count is negated.
* test-suite/tests/numbers.test: Add tests.

This is a followup to commit 011aec7e240ef987931548d90c53e6692c85d01c.
When rounding, right shifting a negative integer by a huge shift count
results in 0, not -1.
* libguile/numbers.c: Add top-level 'verify' to ensure that the
assumptions in 'scm_ash' and 'scm_round_ash' are valid.
(scm_round_ash): In the case that handles huge right shifts, require
that the shift count _exceeds_ the integer length, and return 0 instead
of -1.
* test-suite/tests/numbers.test: Adjust tests accordingly.

Fixes <https://bugs.gnu.org/32644>.
Reported by Stefan Israelsson Tampe <stefan.itampe@gmail.com>.
The need for this arose because the type inferrer for 'ursh' sometimes
passes (- 1 (expt 2 64)) as the second argument to 'ash'.
* libguile/numbers.c (scm_ash, scm_round_ash): Gracefully handle several
cases where the shift count does not fit in a C 'long'.
* test-suite/tests/numbers.test: Add tests.

Reported by Josh Datko <jbd@cryptotronix.com>.
* libguile/validate.h (SCM_VALIDATE_LIST_COPYLEN)
(SCM_VALIDATE_NONEMPTYLIST_COPYLEN): Use '!=' instead of '>=' to
validate the result of 'scm_ilength' after it has been stored in
the user variable 'cvar'.

instead of ':use-module' in 'define-module' form.

failing to track the register state correctly.

Fixes <https://bugs.gnu.org/32786>.
'scm_atomic_compare_and_swap_scm' is a thin wrapper around
'atomic_compare_exchange_weak' (where available), and therefore it may
spuriously fail on some platforms, leaving the atomic object unchanged
even when the observed value is equal to the expected value. Since
'scm_atomic_compare_and_swap_scm' returns both a boolean result and the
observed value, the caller is able to detect spurious failures when
using that API.
'atomic-box-compare-and-swap!' presents a simpler API, returning only
the observed value. The documentation advises callers to assume that
the exchange succeeded if the observed value is 'eq?' to the expected
value. It's therefore not possible to report spurious failures with
this API.
'atomic-box-compare-and-swap!' uses 'scm_atomic_compare_and_swap_scm',
and prior to this commit would simply ignore the boolean result and
return the observed value. In case of spurious failures, the caller
would legitimately conclude that the exchange had succeeded.
With this commit, 'atomic-box-compare-and-swap!' now retries in case of
spurious failures.
* libguile/atomic.c (scm_atomic_box_compare_and_swap_x): If
'scm_atomic_compare_and_swap_scm' returns false and the observed value
is equal to 'expected', then try again.
* libguile/vm-engine.c (atomic-box-compare-and-swap!): Ditto.
|
|
* libguile/jit.c (compile_f32_set): Fix to write an f32, not a f64.

* doc/ref/compiler.texi (Bytecode): Update macro-assembler instructions,
and move most of them to the instruction set reference.
* doc/ref/vm.texi (A Virtual Machine for Guile, VM Programs): Minor
fixes.
(Instruction Set): Update for Guile 3 instruction set.
* libguile/vm-engine.c (vm_engine): Update a few instruction
docstrings.
|
|
* libguile/posix.c (scm_init_posix): Define AT_SYMLINK_NOFOLLOW,
AT_SYMLINK_FOLLOW, AT_NO_AUTOMOUNT, and AT_EMPTY_PATH when available.
(scm_utime): Mention AT_SYMLINK_NOFOLLOW.
* doc/ref/posix.texi (File System): Update accordingly.

the abort hook was enabled, cache registers first to avoid restoring
a bad IP to the VM.
|
|
