rounding functions treat minus zero more consistently.
* bug fix: disassembly of stack allocation of vectors caused a crash.
(reported by bohonghuang)

without additional consing.
* Tue Apr 02 2024 John Paul Adrian Glaubitz <adrian.glaubitz@suse.com>

respects the SOURCE_DATE_EPOCH environment variable (if set) as the latest
timestamp to be used.

* system integrity: compiling the system itself on x86-64/linux now produces
bitwise-identical cross-compiled fasls whether the build host is cmucl,

- Use existing sbcl package by default to build sbcl
* Mon Jan 01 2024 John Paul Adrian Glaubitz <adrian.glaubitz@suse.com>
- Update to version 2.4.0

to NIL when the system is started with the --script command-line argument.
(reported by Hraban Luyat, thanks to Nicolas Martyanoff)

standard (CL) symbols ARRAY-RANK, ARRAY-TOTAL-SIZE, PATHNAME-HOST,
PATHNAME-TYPE, PATHNAME-DIRECTORY, FLOAT-RADIX or FLOAT-DIGITS.
(lp#2045559)
* platform support

* Wed Dec 06 2023 John Paul Adrian Glaubitz <adrian.glaubitz@suse.com>
- Update to version 2.3.11
* minor incompatible change: streams with an external-format specified with
:REPLACEMENT will use their replacement data once per stream unit that
causes a decoding error (rather than, in some cases, once for a sequence
of bytes none of which is a valid character start position for that
external-format).
* minor incompatible change: external-format designators with unsupported or
unrecognized options now signal an error when used.
* enhancement: During generic function dispatch, for a generic function
using standard- or short-method-combination, if there are no applicable
primary methods the system will call the generic function
SB-PCL:NO-PRIMARY-METHOD, whose default behaviour is to signal an error.
Users may define methods on this generic function.
* enhancement: external formats for unibyte encodings and utf-8 now support
newline variants.
* enhancement: character decoding and encoding errors signalled by stream or
octet functions now provide a USE-VALUE restart for handlers to provide
replacement input or output.
* enhancement: READ-SEQUENCE and WRITE-SEQUENCE support user-defined
sequences; the default implementation proceeds element-by-element, reading
or writing single bytes or characters to or from the stream as
appropriate.
* bug fix: OCTETS-TO-STRING using unibyte external formats with unallocated
codepoints (e.g. iso-8859-3) correctly signal or use replacements rather
than taking bits from the address of NIL and converting those bits to
a character.
* bug fix: FILE-STRING-LENGTH now returns NIL if the input datum is not
encodable in the stream's external format.
* bug fix: table-based multibyte external formats (EUC-JP, Shift-JIS, GBK)
now honour a replacement character (in the external format or through
restarts) when encoding to octets.
* bug fix: converting from octets using the UCS-2, UCS-4 and UTF-32 external
formats no longer reads past the end of an octet array with a non-integral
number of two- or four-byte units.
* bug fix: converting from octets using the UCS-2, UCS-4, UTF-16 or UTF-32
external formats now returns a simple string, as required by the type
declaration of OCTETS-TO-STRING.
* bug fix: providing an invalid external format argument to OPEN or
WITH-OPEN-FILE (or the internal MAKE-FD-STREAM) no longer leaks a file
descriptor.
* bug fix: SB-ROTATE-BYTE recognizes out-of-relevant-range BYTE
specifications for integers before attempting to cons up enormous bignums
for masking and shifting. (lp#2042937)
* bug fix: fix type derivation on compiling SB-ROTATE-BYTE forms with
non-zero POSITION in the byte specifier. (lp#2042775)
* bug fix: fix multiple assembler errors when compiling MAKE-ARRAY,
MAKE-STRING and similar with a large constant size. (lp#2037347, lp#2038744)
* bug fix: fix internal error when compiling (SETF SBIT) with a large
constant index. (lp#2037415)

LABELS. (lp#2040334)
* bug fix: fix internal compiler error when compiling some
infinitely-recursive LABELS forms. (lp#2042704)
* bug fix: fix internal compiler error when attempting to inline a jump to a
label that has been deleted. (lp#2043262)
* bug fix: FILL-POINTER should never be made to go negative. (lp#2042452)
* optimization: external formats with :REPLACEMENT no longer bind handlers
for coding errors around conversion functions, and so should cons less and
be faster.
* optimization: when the :EXTERNAL-FORMAT argument to STRING-TO-OCTETS or
OCTETS-TO-STRING is a compile-time constant, the external format is
resolved at load time rather than on each call.
* optimization: the compiler is able to constrain the types of inputs to
some functions given a derived or asserted type of the function's return
value.
* optimization: the compiler performs fewer redundant type checks in ASSOC,
GETF and similar functions.
* Thu Nov 02 2023 John Paul Adrian Glaubitz <adrian.glaubitz@suse.com>
- Update to version 2.3.10
* enhancement: The compiler now allows stack allocating vectors of any size
on all safety levels, not just those which it can prove are of sub-page
sizes. It can do this because it now inserts code to check for stack
overflow explicitly on higher safety levels.
* enhancements to the disassembler:
* * on arm64, x86-64, DISASSEMBLE annotates references to static symbols.
* bug fix: calls to generic functions now detect erroneous keywords (in the
sense of CLHS 7.6.5) passed as arguments even when auxiliary methods are
applicable.
* bug fix: the standard method on SB-MOP:COMPUTE-EFFECTIVE-METHOD no longer
inserts calls to implementation-defined local macros. (reported by Daniel
Kochmański)
* bug fix: compiler error from state-machine-like LABELS forms in some
circumstances. (lp#2037318)
* bug fix: fix compile-time error in constant-folding RATIONAL on literal

with immediates. (lp#2037456)
* bug fix: infinite loop in the compiler for simplification of type tests of
complicated union types. (lp#2038112, reported by Paul M. Rodriguez)
* bug fix: inability to dump a literal displaced array containing copies of
its displacement target. (lp#2038233, reported by James Kalenius)
* bug fix: compiler error in LOGBITP type derivation. (lp#2038241)
* bug fix: compiler error in AREF type derivation. (lp#2038659)
* bug fix: compiler internal consistency failure in overflow type checks.
(lp#2038736)
* bug fix: work around an infinite loop in type simplification by not
providing such types from the compiler. (lp#2038980, reported by Richard
Holcombe)
* bug fix: spurious run-time argument count errors from generic function
calls on arm64. (lp#2039006, reported by fiddlerwoaroof)
* bug fix: errors in SCALE-FLOAT on floating-point infinities. (lp#2039613)
* bug fix: ROOM is slightly more robust to incompletely-initialized
instances at the point of running ROOM. (Reported by Andreas Franke)
* bug fix: finalizers saved through SAVE-LISP-AND-DIE and subsequently
executed do not trigger memory faults. (Reported by Bohong Huang)
* optimization: improvements to type derivation for ISQRT, INTEGER-LENGTH,
LOGCOUNT, LOG, DENOMINATOR.
* Tue Oct 03 2023 John Paul Adrian Glaubitz <adrian.glaubitz@suse.com>
- Update to version 2.3.9
* enhancement: stack allocation via DYNAMIC-EXTENT now applies to all values
that a variable can take on (for example via SETQ), not just the initial
binding. This permits for example building complex or recursive structures
on the stack more easily via iteration. See the updated manual entry for
more details.
* minor incompatible change: some interfaces in the SB-POSIX contrib module
adhere to the spec that a NULL result from the C library is an error if
and only if errno was altered by the call. SYSCALL-ERROR will be signaled
if so.
* enhancement: the SB-POSIX contrib module provides DO-PASSWDS and DO-GROUPS
to allow users to iterate over password and group databases safely.
* platform support:
* * support for Darwin on x86 and PowerPC has been restored. (lp#2033287,
thanks to Kirill A. Korinsky, Sergey Fedorov and barracuda156)
* bug fix: miscompilation due to erroneous type derivation in the presence
of multiplication of fixnums by ratios. (lp#2033695, reported by Patrick
Dussud)
* bug fix: compiler error when compiling signed- and unsigned 64-bit type
checks in some cases. (lp#2033997, reported by Eric Smith)
* bug fix: compiler error when the :INITIAL-CONTENTS argument to MAKE-ARRAY
is a constant non-sequence. (lp#2037328)
* bug fix: compiler error when constant-folding sequence functions with
:TEST or :KEY functions erroring on the given sequence. (lp#2037341)
* bug fix: compiler error when arguments to array or sequence functions
imply a very large sequence size. (lp#2037443, lp#2037348)
* bug fix: compiler error when the return value of ADJUST-ARRAY is not used.
(lp#2037450)
* optimization: function types derived by the compiler can in some cases be
propagated backwards through the intermediate representation.
* optimization: better type derivations for LDB, LOGBITP, RATIO.

comparisons.
* Tue Aug 29 2023 John Paul Adrian Glaubitz <adrian.glaubitz@suse.com>

build-time option; it can be enabled by adding
`--without-gencgc --with-mark-region-gc`
to the build command line. (Thanks to Hayley Patton)
* enhancement: Stack allocation via DYNAMIC-EXTENT is now possible for
conditionals even when not all branches are stack-allocatable. Previously
all branches needed to be stack-allocatable for the otherwise-inaccessible
subparts to get stack allocated.
* platform support:
* * on Mac OS X Sonoma, loading the memory image no longer fails.
(lp#2029430, reported by cladur)
* * on Darwin, we no longer reimplement nanosleep().
* * on PPC64, undefined function errors now work.
* * on ARM64/OpenBSD, enable the GCC TLS feature. (thanks to Sébastien
Marie)
* * when building the system, only display a reasonable amount of timing
precision. (thanks to Philipp Marek)
* bug fix: handling of inlining functions compiled to return unboxed values
no longer crashes the compiler. (lp#2029020, reported by Pascal

- Refresh patches for new version
+ strip-arm-CFLAGS.patch
* Tue Feb 28 2023 John Paul Adrian Glaubitz <adrian.glaubitz@suse.com>
- Update to version 2.3.2
* incompatible change: the :ORDER long-form-option in
DEFINE-METHOD-COMBINATION accepts NIL as well as :MOST-SPECIFIC-FIRST and
:MOST-SPECIFIC-LAST. A value of NIL implies no particular ordering of the
methods, and so disables checks of multiple methods with the same
specializers in that group.

properly, avoiding an infinite loop in DEFINE-METHOD-COMBINATION if the
:ORDER argument leads to a cycle of compile-time constants.

* bug fix: better compile time when the compiler needs to perform checks to
see if fixnum or word computations result in overflow. (lp#2007741)

Westfold)
* optimization: on x86-64, use SIMD instructions for UTF-8 buffer decoding;
* various type-driven optimizations:
* * comparisons of rationals with constant ratios or floats;
* * comparisons of unsigned-bytes with fixnums;
* * comparisons of fixnums with constant powers of two;
* * equality of numbers with integers too large to be exactly represented
as floats;
* * arithmetic operations on a mixture of signed and unsigned word-sized
quantities;
* Mon Jan 30 2023 John Paul Adrian Glaubitz <adrian.glaubitz@suse.com>
- Update to version 2.3.1

more consistent with the required semantics in IEEE 754 when comparing
with rationals.

the compiler can prove it's safe even on high safety.
* optimization: addition of a fixnum to a bignum generates less garbage.
* optimization: in many cases, type inference and code generation is
improved for and around numerical comparison functions.

upstream git commit [lp#1983218].
* Wed Aug 10 2022 John Paul Adrian Glaubitz <adrian.glaubitz@suse.com>
- Update to version 2.2.7
* minor incompatible change: the compiler emits full WARNINGs for undefined
references to variables in TYPE and DYNAMIC-EXTENT declarations, and for
SETQ of an undefined variable. (This was the historic behaviour for
everything except the DYNAMIC-EXTENT case, which used to emit a
STYLE-WARNING, but these diagnostics got lost in a refactoring since

(lp#1393302)
* minor incompatible change: RENAME-FILE now overwrites the target file on
Windows too, making its behaviour consistent with other platforms.

* enhancement: better constraint propagation in the compiler. Specifically,
the compiler can now derive the type of X in control flow join situations
such as
(LAMBDA (X) (ECASE (1 ...) (2 ...)) X)
or
(LAMBDA (X) (ETYPECASE (INTEGER ...) (SYMBOL ...)) X)
instead of forgetting all information about X after the E(TYPE)CASE.
