* incompatible change: the compiler's internal representation of "source
paths" for unquoted forms within backquotes has changed. Other developer
tools using this representation, including callers of some exported
SB-INTROSPECT functions, will misreport the location of signalled

commas.

reader errors.

identical code folding at the end of the build of the SBCL system itself.
* enhancement: improve the compiler's knowledge of the dimensions of the
result of MAKE-ARRAY. (lp#2130477, thanks to Vasily Postnicov)
* enhancement: the SB-COVER contributed module has been made substantially
more robust; collecting coverage no longer inhibits various CLOS
optimizations. (For SBCL developers, it is now capable of reporting on
the coverage of the SBCL system itself, provided it is built with the new
:SB-COVER-FOR-INTERNALS build-time feature.)

than SPEED.

* enhancement: the compiler now recognizes when local functions (both named
and anonymous) are used only as downward funargs in many situations and
can stack allocate such closures even without explicit dynamic extent
declarations. See the updated manual entry on stack allocation for more
information and how user-code can declare funargs as downward.
* minor incompatible change: optimization notes for a variable declared to
be of type LIST will not be emitted for various transforms which are
defined to operate on (OR NULL VECTOR).

previously.

* optimization: allow the result of MAKE-STRING to be allocated on the stack
when :element-type is unknown.

intermediate result.
OBS-URL: https://build.opensuse.org/package/show/devel:languages:misc/sbcl?expand=0&rev=237

stepper based on breakpoints requiring no extra instrumentation. However,
it still has less functionality than the existing single stepper. See the
new debugger manual section titled "Breakpoint Commands" for more
information on the new commands.

restored to match the documentation. (lp#2096995, reported by Zach Beane)
* minor incompatible change: invoking CHANGE-CLASS from user code no longer
grabs the CLOS world lock. Callers must take responsibility for ordering
execution of CHANGE-CLASS and any changes to the class hierarchy.

* minor incompatible change: in some instances when the compiler cannot
prove that a NIL-valued branch is unreachable, where NIL is not compatible
with the expected type, a type warning will no longer be issued.
* minor incompatible change: the compiler will more strictly treat type
declarations for &OPTIONAL and &KEY arguments in FTYPE declarations, no
longer effectively adding an implicit (OR ... <default>) type when the
function itself has a default value not matching the declared type for
that argument.

with a USE-VALUE restart provided.
* enhancement: CHECK-TYPE warns about type conflicts at compile-time.

related to complex type checks only at high SPEED optimization settings.

the SB-THREAD package. (thanks to Philipp Marek)

USE-PACKAGE are resolved once for each name, rather than between pairwise
colliding symbols.

default initforms cause compile-time warnings.

** fix constant-folding of %log1p and %log2 on 32-bit x86.
** fix the encoding of popcntd on ppc64

the same name from the same package.

with NULL during the evaluation of the result clause. (lp#942237)

(lp#2069345, reported by Dan Bothell)
* bug fix: resolve the circularity between the type system and the CLOS
metaobject protocol more robustly. (lp#2069502, reported by Jan Moringen)
* bug fix: misplaced tilde in a logical pathname error message.
(lp#2069995, thanks to Marco Heisig)

- Update to version 2.4.5
* incompatible change: attempting to pass or return alien structs by value
now signals errors. Previously, such attempts would silently tend to
corrupt registers or memory; there is work in progress to allow such calls
conforming to the platform ABI. (thanks to Rongcui Dong)
* minor incompatible change: function debug info is compressed only if the
system is compiled with libzstd, rather than falling back to a pure-lisp
compression implementation.
* minor incompatible change: the compiler will warn in more cases when it
can detect incorrectly-typed arguments to FORMAT directives ~C and ~R
* minor incompatible change: strings are converted to a more compact
representation if possible before being used as docstrings.
* platform support:
** explicitly include stdlib.h where needed on OpenBSD. (thanks to
Sebastien Marie)
** make the editcore utility work on Windows. (thanks to Luís Borges de
Oliveira)
** fix memory initialization in RUN-PROGRAM on Windows.
** resolve a deadlock in %INTERRUPT-THREAD on Darwin. (lp#2062940,
reported by Yan)
** hang on startup under some terminal emulators on OS X 14.5.
(lp#2067313, reported by Richard M Kreuter)
* enhancement: when (> debug 1), try to find source locations for code
expanded from macros that copy their input forms.
* bug fix: the method-combination generic function caches were missing some
of the generic functions constructed during the PCL build itself.
(reported by Didier Verna)
* bug fix: SXHASH on equal PATHNAME objects could return different values in
different cores. (reported by Luís Borges de Oliveira)
* bug fix: spurious compiler warnings on SORT in some circumstances.

- Update to version 2.4.4
* minor incompatible change: after-GC hooks are now called in the finalizer
thread on threaded builds.
* platform support:
** on win32 on 64-bit systems, clear x87 state as well as SSE state after
an exception. (lp#2000435, reported by David Scherfgen)
* enhancement: type assertions resulting from declarations involving variable
numbers of multiple values are now checked.
* enhancement: support for memory allocation arenas is now available on the
arm64 platform.
* enhancement: the cross-referencing facility is now able to handle
anonymous functions.
* enhacnement: the SB-INTROSPECT contrib finds callees in methods of generic
functions.
* bug fix: inconsistency in VOP definitions implementing DPB. (lp#2059842)
* bug fix: MASK-FIELD miscompilation. (lp#2059849)
* bug fix: caching a state-dependent type function leads to wrong type
inference further down the line. (lp#2059888)
* bug fix: internal consistency violation after failing to apply a
MAKE-ARRAY transform. (lp#2060083)
* bug fix: check the array index before constant-folding an array reference.
(lp#2060347)
* bug fix: don't try to apply type constraints from SATISFIES
types. (lp#2060756)
* bug fix: the JOIN-THREAD-PROBLEM function is now exported from the
SB-THREAD package. (lp#2063385, thanks to Benjamin Lee)
* bug fix: compare-and-swap works as expected on SLOT-VALUE of
FUNCALLABLE-STANDARD-OBJECT instances. (reported by qhong)
* bug fix: on arm64, and x86-64 with some non-default build options, integer
rounding functions treat minus zero more consistently.

- Update to version 2.4.3
* enhancement: when dumping debug information to fasl files, the system
respects the SOURCE_DATE_EPOCH environment variable (if set) as the latest
timestamp to be used.
* contributed module: the sb-perf contributed module, an interface
originally by Luke Gorrie to Linux's perf, is now included by default on
Linux. (Thanks to Philipp Marek)

space.
** PPC64: allow configuring the system with fasteval.
* bug fix: erroneous transform of EQUALP on characters (lp#2055425)
* bug fix: float rounders (FTRUNCATE and related functions) handle minus
zero more consistently, returning minus zero as the primary value when
rounding to zero from a negative value.
* bug fix: type checks for (VECTOR T) were giving the wrong answer for
vectors displayed to simple multi-dimensional arrays. (reported by
_death)
* bug fix: do not transform away division by BIT when the BIT might still
include 0. (lp#2056184, reported by xizang)
