- Update to version 2.3.7
* minor incompatible change: MACROLET macro functions are now compiled with
(SPEED 1), leading to fewer efficiency notes being emitted when compiled
in otherwise high-SPEED environments.
* minor incompatible change: when coalescing list data, the file compiler
respects substructure equality more accurately, with the side-effect of
coalescing along CDR chains as well as CARs. (lp#2025086)
* minor incompatible change: FUNCTION type declarations for local variables
generate assertions around their use when called.
* platform support

- 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.
* bug fix: evaluate the :ORDER long-form-option in DEFINE-METHOD-COMBINATION
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 on chains of conditionals which have gaps in
integer ranges. (lp#1992349, reported by Mykola Matvyeyev)
* bug fix: type derivation of VECTOR-LENGTH leading to wrong type handling
for MEMBER types involving vectors. (lp#2004094)
* bug fix: equality constraint propagation in the presence of constants
could cause code to be not deleted when it should have been. (lp#2006487)
* bug fix: better compile time when the compiler needs to perform checks to
see if fixnum or word computations result in overflow. (lp#2007741)
* bug fix: miscompilation on ARM64. (lp#2007758, reported by Stephen
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
* sb-graph has been removed. To visualize IR1 in sbcl, it is recommended to
use the function IR1-TO-DOT (which only survives the final tree shake if
the feature :sb-devel is enabled at build time).
* platform support:
* * implement some peephole optimizations on arm64;
* * support float traps on arm64;
* bug fix: package-manipulation operations within fasls work as expected in
the absence of explicit block compilation requests. (lp#2000004, reported
by Shubhamkar Ayare)
* bug fix: incorrect type simplification of certain CONS types.
(lp#1999352, reported by Paul Dietz)
* bug fix: method combination group selection interprets the symbol * as
a wildcard element within proper qualifier-pattern lists. (reported by
Maciej Katafiasz and by Daniel Kochmański)
* bug fix: &WHOLE can be used without error in define-method-combination
arguments lambda lists. (reported by Daniel Kochmański)
* bug fix: bogus debug variables generated for closure variables whose value
cell had not yet been allocated could cause segfaults and gc crashes
(reported by _death on #sbcl)
* bug fix: handling of float NaNs in two-arg numeric comparison functions is
more consistent with the required semantics in IEEE 754 when comparing
with rationals.
* bug fix: ensure that the hide-packages test passes even when the system
retains internal cross-reference metadata. (lp#2002896, reported by 3b)
* bug fix: don't trip an internal assertion in weak hash tables with
finalizers. (lp#1998064)
* optimization: load-time only code is no longer retained at runtime when
functions close over top level bindings.
* optimization: GO and RETURN-FROM now elide out-of-extent tag checks when
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.
* Tue Jan 03 2023 John Paul Adrian Glaubitz <adrian.glaubitz@suse.com>
- Update to version 2.3.0
* enhancement: support for SLOT-VALUE and friends has been extended to
structure and condition instances.

- Add sbcl-allow-value-cell-value-in-RO-space.patch: Allow that
value-cell-value can move to R/O space, to fix build failures
for maxima and other sbcl dependencies; patch taken from
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
sbcl-2.2.2)
* minor incompatible change: literal objects (strings, in particular)
in compiled code may at the discretion of the runtime be placed in

- Update to version 2.2.5
* minor incompatible change: SB-EXT:*DERIVE-FUNCTION-TYPES* being NIL now
means that function calls will strictly only use type information from
proclaimed ftypes. The previous behavior (still the default) of using
derived type information from the same file is specified with :SAME-FILE.
(lp#1393302)
* minor incompatible change: RENAME-FILE now overwrites the target file on
Windows too, making its behaviour consistent with other platforms.
* minor incompatible change: inlining of local function is inhibited if
policy DEBUG = 3.
* platform support:
* * single-stepping is now supported on 64-bit PowerPC platforms. (thanks
to Thomas Fitzsimmons)

reported by Sean Maher)
* bug fix: streams opened from RUN-PROGRAM but left unclosed because of a
non-local exit no longer cause unrelated streams to be closed later.
* Wed May 25 2022 John Paul Adrian Glaubitz <adrian.glaubitz@suse.com>
- Update to version 2.2.4
* 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.
* optimization: inlined functions enclosed in local macro definitions no
longer save their entire lexical environment, reducing unnecessary
memory retention.
* optimization: faster (< integer fixnum) comparisons (ARM64 and x86-64).
* platform support:
* * RUN-PROGRAM is faster on Linux and FreeBSD if close_range(2) is
available.

* optimization: fasls containing standard object literals are now smaller
and load more efficiently.
* optimization: faster arithmetic (*-+) on word-sized integers when the
result is not known to fit into a word (ARM64 and x86-64).
* bug fix: EQness of constants is now always preserved when block compiling.
* Mon Feb 28 2022 John Paul Adrian Glaubitz <adrian.glaubitz@suse.com>
- Update to version 2.2.2
* platform support:
* * all architectures now share the coverage mark instrumentation
implementation, meaning that performance now equals what had been
implemented only on x86 architectures.
* * fixed a performance regression on x86-64 from changes in AVX2 register
handling. (lp#1960081, reported by Michael Kappert)
* * fixed a garbage collection bug on ppc64 manifesting in occasional
corruption on threaded programs. (lp#1959338, lp#1952973)

undergoes a non-local exit, restore the instance to its original state.
(thanks to Michał phoe Herda)
* enhancement: the :SYNCHRONIZED keyword argument to MAKE-HASH-TABLE is no
longer experimental.
* bug fix: fix an erroneous compiler tranform for (EXPT SINGLE-FLOAT
INTEGER). (lp#1958061, thanks to Vasily Postnicov)

if more than one closure closes over the same environment. (lp#1956870,
reported by Michał phoe Herda)

* bug fix: a portability issue arising from various build hosts
(lp#1886255, reported by Pierre Neidhart)
* bug fix: spurious compiler warnings from REDUCE with :INITIAL-VALUE.
(lp#1885515, reported by Michael South)
* bug fix: an inconsistency between class hierarchies and the type system
under some circumstances involving redefinition. (lp#1886397, reported by
Atilla Lendvai)
* bug fix: the USE-VALUE restart for OPEN on non-existent files is more
likely to function as expected. (lp#1886587)
* bug fix: various invalid inputs to ROTATE-BYTE no longer cause compiler
errors. (lp#1887164, lp#1888152)
* optimization: PPC64 on linux uses the __thread annotation on C variables
in preference to pthread_setspecific() and pthread_getspecific().
* Tue Jun 30 2020 John Paul Adrian Glaubitz <adrian.glaubitz@suse.com>
- Update to version 2.0.6
* planned incompatible change: the defined symbols in the Metaobject
Protocol, currently accessible from both SB-MOP and SB-PCL packages, will
in a later release be no longer exported from SB-PCL.
* platform support:
* * better support for dynamic-extent on the SPARC architecture.
* * bug fix for loading very large core files.
* * bug fix for logior and logxor on PPC64.
* enhancement: EQUALP on structure instances uses code specialized
to each structure type, inlining comparison of non-pointer slots.
* enhancement: some standard operators, such as WITH-OUTPUT-TO-STRING and
CHANGE-CLASS, have been adapted to use dynamic-extent temporary objects,
and so cons less garbage on the heap.
* enhancement: read tables are more space- and speed efficient
* bug fix: stream conditions with dynamic-extent streams have the stream
replaced by a stub. (reported by Matt Kaufmann)
* bug fix: garbage collections triggered from foreign callbacks crashed.
(lp#1884403, reported by Andrew Kent)
* bug fix: compiler failure in compiling MAKE-LIST. (lp#1881349)
* bug fix: using the debugger from frames with calls to functions with
unsupplied optional arguments is less likely to cause heap corruption.
(lp#1883745)
* Mon Jun 01 2020 John Paul Adrian Glaubitz <adrian.glaubitz@suse.com>
- Update to version 2.0.5
* platform support:
* * experimental support for ARM32 and ARM64 on OpenBSD
* * better musl libc support. (lp#1768368, thanks to Eric Timmons)
* * more correct use of futexes on 64-bit Linux. (lp#1876825, reported by
Ilya Perminov)
* * restore building on current Solaris. (lp#1881393, thanks to Shawn
Ellis)
* enhancement: CMUCL-style START-BLOCK and END-BLOCK declarations are now
supported for block compiling forms at a sub-file granularity.
* enhancement: IPv6 support in sb-bsd-sockets is enabled on Windows.
* minor change: *compile-print* now makes it more clear what block
compilation is actually doing. The default output is now slightly more
verbose as a result.
* bug fix: number keys in EQUALP hash tables are correctly hashed.
(lp#1878653, reported by Syll)
* bug fix: EQness is better preserved given partial sharing of list contents
in the file compiler. (lp#1583753, reported by Denis Budyak)
* bug fix: the peephole pass neglected to preserve jump table labels.
(lp#1876485)
* bug fix: fix compiler crash in block compilation merging of toplevel
lambdas. (lp#1865336, reported by il71)
* bug fix: sb-introspect's function-lambda-arglist is better at extracting
default values of nested macro arguments. (lp#1876194)
* bug fix: RESTART-BIND's body is an implicit progn, and so does not accept
declarations. (lp#1876303, reported by Michal Herda)
* optimization: EQUAL hash tables with keys involving structure-objects will
have fewer systematic collisions.
- Fix architecture mapping for riscv64 in spec file
* Tue Apr 28 2020 John Paul Adrian Glaubitz <adrian.glaubitz@suse.com>
- Update to version 2.0.4
* platform support:
* * 32-bit RISC-V is now fully supported. Unlike other ports, its backend
is entirely shared with 64-bit RISC-V.
* * native threads are now supported on RISC-V.
* * fix and add some x86-64 vector instructions. (reported by Shubhamkar
Ayare)
* * improve pointer representation on ppc64 for low-level performance
improvement.
* * threads are more stable on big-endian ppc64
* enhancement: forward-referenced type tests can now be open-coded by using
block compilation. The result is that mutually referential defstructs are
now efficiently compiled in block compilation mode, superseding a lighter
mechanism that worked in fewer contexts. However, that lighter mechanism
has been removed, so for now, users who want to efficiently compile
mutually referential defstructs must explicitly opt-in using block
compilation.
* bug fix: defstructs with empty initforms in the sbcl source are now
explicitly intiialized with NIL, as that is undefined behavior under
ANSI. This helps cross compilation hosts which do not implicitly
initialize empty initform slots to NIL. (Thanks to Karsten Poeck)
* bug fix: backtracing through assembly routines now works properly on
RISC-V.
* bug fix: ASH no longer gets miscompiled in certain edge cases on RISC-V.
* bug fix: &MORE args have been slightly optimized and are more correct on
RISC-V.
* bug fix: unused local functions with &REST/&KEY/&OPTIONAL now also issue a
deletion note.
* bug fix: APPLY on a large list ("large" being in excess of 2k to 16k items
depending on the platform) can no longer crash the gencgc collector.
* bug fix: sb-concurrency FRLOCK algorithm has been corrected. (lp#1087955)
* bug fix: block compilation now respects inlining declarations better (like
CMUCL).
* optimization: hashing of structures with raw slots for EQUALP hash tables
has been improved.
* Sun Mar 29 2020 John Paul Adrian Glaubitz <adrian.glaubitz@suse.com>
- Update to version 2.0.3
* incompatible change: the external format now defaults to UTF-8 and is not
affected by LANG. sb-ext:*default-external-format* is now the only way to
change it.
* minor incompatible change: the undocumented :EPHEMERAL argument to
MAKE-THREAD has been removed.
* minor incompatible change: DECLARE type testing of structure types when
the SAFETY optimization quality is less than SPEED (but greater than 0) is
precise, rather than merely testing that an object is a (general)
STRUCTURE-OBJECT.
* platform support
* * respect sunos platform assembler flag handling
* * riscv architecture can be detected during the build
* * enabled the sb-dynamic-core feature on riscv, sparc, and made it
unconditional everywhere
* * cheneygc is an option for arm and arm64
* enhancement: the installed sbcl executable tree can be renamed or moved
without risk of incorrectly referencing a '.core' file from an obsolete
path. (lp#666086)
* optimization: transform (values-list (list one-item)) to (values one-item)
as multiple items were already recognized.
- Drop patches merged upstream
+ ppc-ppc64le-fix-LINKFLAGS.patch
- Enable bootstrapping sbcl with clisp on ppc64 and riscv64
* Fri Mar 13 2020 John Paul Adrian Glaubitz <adrian.glaubitz@suse.com>
- Update to version 2.0.2
* new feature: CMUCL-style block compilation support has been added,
allowing whole program optimization. It has been documented in a new
section of the manual entitled "Advanced Compiler Use and Efficiency
Hints". In particular, users of block compilation will find a large
speedup for numerical code, as functions which call or return floating
point values will keep everything unboxed.
* bug fix: in CHANGE-CLASS, handle non-standard slot-value-using-class for
:INSTANCE and :CLASS slots better. (reported by Shinmera on #sbcl)
* bug fix: REMHASH in an EQUAL or EQUALP hash-table works correctly on a
key for which EQUAL (respectively EQUALP) is reduced to EQ. (lp#1865094)
* bug fix: do not emit a warning for DEFCLASS slots with mismatched :TYPE
and :INITFORM when the class has a non-standard metaclass.
* bug fix: DISASSEMBLE on SPARC is less likely to spuriously annotate code
sequences as error traps.
- Add patch to add missing linker flags to LINKFLAGS on ppc and ppc64el
+ ppc-ppc64le-fix-LINKFLAGS.patch
- Refresh patches for new version
+ strip-arm-CFLAGS.patch
* Sun Feb 02 2020 John Paul Adrian Glaubitz <adrian.glaubitz@suse.com>
- Update to version 2.0.1
* minor incompatible change: some symbols have been removed from *FEATURES*
based on a determination of which should be impermissible to examine
via #+ and #- reader macros in user-written code.
* optimization: DEFSTRUCT copiers including COPY-STRUCTURE are able to
stack-allocate the result when declared dynamic-extent.
* bug fix: loop analysis code more robust. In particular, loop nesting depth
is computed more accurately, improving the register allocation around
loops.
- Refresh patches for new version
+ fix-tests.patch
* Wed Jan 01 2020 John Paul Adrian Glaubitz <adrian.glaubitz@suse.com>
- Update to version 2.0.0
* minor incompatible change: heap relocation now works on Windows. Since
this feature now works on all platforms, it is enabled unconditionally and
the :RELOCATABLE-HEAP symbol no longer appears on *FEATURES* in any
builds. (Thanks to Luís Borges de Oliveira)
* enhancement: malformed type specifiers and occurrences of deprecated types
in :TYPE initargs of DEFCLASS and DEFINE-CONDITION slot specifications
are detected and result in compile-time errors and warnings respectively.
* enhancement: parallel contrib building, controlled by SBCL_MAKE_JOBS=-jX
the same as for the C runtime.
* bug fix: add a walker template for WITH-SOURCE-FORM.
* bug fix: start the summary of a compilation unit on a fresh line. (Thanks
to Zach Beane)
* bug fix: on Windows, PARSE-NATIVE-NAMESTRING produces an absolute
directory when parsing a bare drive name and :AS-DIRECTORY is specified.
(Thanks to Luís Borges de Oliveira)
* bug fix: on RISCV, the runtime is linked with libz if the core compression
feature is requested. (Thanks to Andreas Schwab)
* bug fix: ADJOIN using an EQL test and a KEY function only transforms into
an EQ test if the key function returns values for which EQ and EQL are
guaranteed to be the same.
* optimizations:
* * the instruction sequence for multiple-value calls is more
efficient on x86-64.
* * the direction flag is now unused on x86 and x86-64 when handling
an unknown number of return values. (Thanks to Fanael Linithien)
* * the x86-64 backend is better able to use memory operands for arithmetic
operations.
* * compilation of TYPECASE to a jump table is enabled when all the types
being tested are frozen.
* * compilation of CASE and ECASE into a jump table has been implemented on
32- and 64-bit powerpc platforms.
* * the implementation of Unicode normalization has been sped up.
* * pretty-printing dispatch on conses is faster, particularly with the
standard pretty-print dispatch table. Deeply-nested forms should also
pretty-print faster.
* Sat Dec 14 2019 John Paul Adrian Glaubitz <adrian.glaubitz@suse.com>
- Update to version 1.5.9
* platform support:
* * a message intended to be more helpful will be displayed for an mmap
failure on OpenBSD.
* * the soft-float ABI on ARM32 is better supported, in particular in
returning double floats from calls into C.
* optimizations:
* * CASE and ECASE with symbols as keys may be optimized into a vector
lookup if all result forms are quoted or self-evaluating objects.
* * CASE and ECASE can be optimized into a jump table on the x86[-64]
backends with arbitrary result forms provided that the clause keys
are either all fixnums, all characters, or all symbols.
* * a number of forms are converted to use CASE in circumstances where that
makes sense, including calls to POSITION, MEMQ and MEMBER, and TYPECASE
where the types are MEMBER/EQL types.
* * POSITION of a variable symbol in a constant sequence of symbols is
converted to CASE and thence to a jump table.
* * TYPECASE of a variable where the clauses are member types is converted
to CASE and thence to a jump table.
* * a number of slow instructions are no longer used on x86 and x86-64
machines. (Thanks to Fanael Linithien)
* * the compiler is better at tracking the implications of branches after
EQ and EQL tests.
* * parsing &KEY lists is slightly less register-intensive.
* * a pattern-based peephole optimizer pass has been added, running some
simple transformations on the x86-64 backend.
* enhancements: more thorough compile-time type checking of various
initforms (defclass, &key, defstruct).
* bug fix: unions of complicated CONS types are less likely to cause an
infinite loop. (lp#1799719)
* bug fix: DESCRIBE on functions not named by extended function designators
no longer signals a type error. (lp#1850531, reported by Michal Herda)

(lp#1845936)
* * support SSE for bzero if available on OpenBSD
* optimizations:
* * improved type understanding and translations for division operators
(including TRUNCATE, GCD, LCM).
* * sequential comparisons and branches can elide intermediate comparisons.
(lp#1847284)
* * convert EQUAL and EQUALP to EQL if either of the arguments is a type
for which the structural equality predicate is identical to the simpler
equality check. (lp#1848583)
* * internal operators implementing string comparisons produce
simpler-to-consume values. (lp#1848776)
* bug fix: inspecting adjustable arrays and vectors with fill pointers works
better. (lp#1846191, reported by Yves Pagani)
- Changes in 1.5.7
* platform support:
* * many bug fixes to the experimental 64-bit PowerPC/Linux port, to the
extent that the little-endian variant passes all applicable tests in
the regression test suite; the big-endian variant currently has some
failures
* * experimental support for sb-threads on 64-bit PowerPC/Linux
* * support threads on x86-64 Sun OS (lp#1841280)

regarding hebrew letters and hyphens
* enhancement: add a restart to OPEN with :IF-EXISTS :ERROR to allow
re-opening with :APPEND. (lp#806398, reported by Tobias Rittweiler)
* bug fix: compiler optimizations on SEARCH with :FROM-END T didn't account
for the empty sequence. (lp#1844821)
* bug fix: handle SETF of nested empty VALUES correctly. (lp#1806478)
* optimization: FLOOR and CEILING on rationals are simpler, and the
compiler's understanding of them is better.
- Changes in 1.5.6
* platform support:
- experimental support for 64-bit PowerPC running Linux (extending Brian
Bokser's work from 2018), on both the v1 and v2 ABIs
* new feature: SB-EXT:SEARCH-ROOTS discovers paths from live objects to the
roots keeping them alive.
* enhancement: string output streams created with :ELEMENT-TYPE 'BASE-CHAR
use internal buffers of BASE-STRING instead of UCS-4 strings restricted
to the ASCII range, yielding a theoretical 4:1 space reduction.
* optimization: improved make-array type derivation for multi-dimensional
arrays. (lp#1838442)
* bug fix: compliant redefinition of classes whose previous definition
caused argument mismatch errors does not generate errors any more.
(lp#1840595, reported by 3b on #sbcl)
* bug fixes for issues caught by the random tester:
- never derive the type of TRUNCATE on arbitrary numbers as the empty
type. (lp#1838267)

FLOAT-SIGN. (lp#1838337)
- include COMPLEX in the derived type of SIGNUM when appropriate.
(lp#1838333)
- more correct internal type testing for function types. (lp#1838808,
lp#1838888, lp#1838986)

(lp#1837307), float registers in interrupt contexts (lp#1837168)
* bug fix: do not generate version.lisp-expr from git describe if the git
repository is not sbcl's own. (lp#1836663, thanks to Richard Lowe)
* bug fix: compiler crash related to VALUES-LIST on a &REST argument in some
contexts. (lp#1836096, reported by Samuel Jimenez)
* bug fix: compiler hang related to constraint propagation. (lp#1835599,
reported by Mark Cox)

* Tue Jul 16 2019 Jonathan Brielmaier <jbrielmaier@suse.de>
- Update to version 1.5.4
for changes since version 1.4.7 have a look at the NEWS file
- refresh patches:
* fix-tests.patch: remove second part of patch as the grent.2 test
in contrib/sb-posix/posix-tests.lisp doesn't use "hardcoded"
group id anymore
- remove patches:
* 0003-Add-RPM_OPT_FLAGS-to-CFLAGS-for-Linux-builds.patch
* dont-split-doc.patch
* sbcl-1.1.13-personality.patch: code was heavily refactored
- smaller spec clean ups
* Tue May 01 2018 kasimir_@outlook.de
- Patch modified
* 0003-Add-RPM_OPT_FLAGS-to-CFLAGS-for-Linux-builds.patch
* dont-split-doc.patch
- Update to version 1.4.7
* enhancement: better handling of unknown keyword arguments (#1750466)
* enhancement: namestrings can now be computed for certain pathnames
that previously did not have namestrings because of #\. characters
in their name and/or type components.
* bug fix: compiling a SLEEP call with a float positive infinity
argument no longer causes an internal error (#1754081)
* bug fix: keyword arguments provided to a generic function with
EQL-specialized methods are checked more correctly (reported by Syll, #1760987)
- Changes in version 1.4.6
* enhancement: DISASSEMBLE on a symbol naming a macro will disassemble
the expander, not the code that traps attempted FUNCALL of the macro.
* enhancement: The sb-sprof contrib now provides an experimental
interface for accessing collected profiler data.
* enhancement: The instruction-level profiling of the sb-prof contrib
annotates the disassembler output more efficiently.
* optimization: improved dynamic-extent handling of nested variables.
- Changes in version 1.4.5
* minor incompatible change: building with/without the :sb-package-locks
feature is no longer an option. Package locks are always compiled in,
and removing :sb-package-locks from *features* will have no effect.
* enhancement: FIND-PACKAGE does not acquire a mutex
* enhancement: cheneygc can perform heap relocation on startup
* enhancement: in threaded builds, finalizers execute in a system-internal
thread so that a user thread which invokes GC is unblocked from performing
work as soon it returns from GC and invokes any post-GC hooks. As such,
it is more important than before to avoid assumptions about special
variable bindings in finalizers, even in single-threaded code.
* optimization: faster (funcall (or function symbol)) on x86-64.
- Changes in version 1.4.4
* bug fix: pathname accessors such as PATHNAME-DIRECTORY work on SYNONYM-STREAMs.
* bug fix: (pathname-{device,directory,name,type} ... :case :common) works
as expected. In particular MAKE-PATHNAME composed with the accessors
roundtrips properly when both use the same :case. (#1739906)
* bug fix: DIRECTORY no longer gets confused when the value
of *DEFAULT-PATHNAME-DEFAULTS* has a name or type component. (#1740563)

superlinearly (#1241771)
* bug fix: CANCEL-FINALIZATION operates in approximately constant
time per operation (#1587983)

* bug fix: backtrace from arg-count errors on systems other than
x86, x86-64, ARM, and ARM64 now works again.
* bug fix: backtrace from asynchronous interrupts on non-x86,
non-x86-64 systems should now be more reliable.
* enhancement: warnings and errors referring to bindings established
by LET, LET*, FLET and LABELS point to the offending form more accurately.
* enhancement: backtrace for invalid argument count produces the exact
supplied arguments including the extra ones on all platforms
(no longer just x86, x86-64, ARM, and ARM64).
- Changes in version 1.4.3
* enhancement: SLEEP respects deadlines established by SB-SYS:WITH-DEADLINE.
* bug fix: DECODE-TIMEOUT and operators accepting a timeout no longer signal
an error when called with an argument that is of type (real 0) but not (unsigned-byte 62) (#1727789)

* bug fix: sb-safepoint builds are now a lot less prone to deadlocks and
odd crashes (#1424031, #1268710)
* bug fix: argumentless CALL-NEXT-METHOD where specialized-to-T or
unspecialized parameters are mutated now uses the original (non-mutated)
parameter values (#1734771)

global storage for fault addresses (everywhere), and now have cleaner
backtraces (on x86 and x86-64). (#309068)
* bug fix: pathnames with a directory component of the form
(:absolute {:up,:wild,:wild-inferiors}) no longer fail to unparse. (#1738775)
* bug fix: more reliable signal handling on macOS.
- Changes in version 1.4.2
* minor incompatible change: SB-EXT:QUIT is no longer marked as deprecated
and behaves like SB-EXT:EXIT.
* enhancement: ASDF updated to 3.3.1. The ASDF release is dedicated to the
late Elias Pipping who put enormous amounts of work into it despite his
terminal illness. Thank you and rest in peace. (#1681201)
* enhancement: alien routines compiled with '-fsanitize=thread' and/or
'-fsanitize=memory' cause fewer false positives in error reporting.
* optimization: fewer instances of consing float constants at runtime.
* bug fix: a number of compiler bugs detected by Paul F. Dietz' randomized
tester. (#1731503, #1730699, #1723993, #1730434, #1661911, #1729639,
[#1729471], #1728692)
* bug fix: better errors from NAMESTRING and friends on pathnames with
no namestrings. (#792154)
* bug fix: EQUAL and EQUALP compiler transforms were too confident in
deriving a result. (#1732277, #1732225)
* bug fix: FILL sometimes returned the underlying data vector rather
than the given array. (#1732553)
* bug fix: SEARCH returned the wrong answer in some cases. (#1732952)
* bug fix: the type (COMPLEX INTEGER) behaves more as specified by
Function TYPEP, which has stronger constraints than System Class
COMPLEX. (Reported by Eric Marsden, #1733400)
* Thu Nov 09 2017 sweet_f_a@gmx.de
- Update to version 1.4.1
* optimization: faster foreign callbacks.
* enhancement: complex arrays can be stack allocated.
* enhancement: PROCESS-KILL now exists on win32 and PROCESS-PID
actually returns the PID.
* optimization: the register allocation method used by the
compiler when optimizing for speed is now faster for functions
with large bodies.
* bug fix: SB-INTROSPECT:ALLOCATION-INFORMATION works on
big-endian CPUs (fixes #490490 for real rather than by
disabling a test)
* bug fix: code objects and bignums of large enough size to be
placed on GC pages without any other object no longer cause
accidental copying during garbage collection. (gencgc only)
* bug fix: sb-fasteval failure with 0-argument lambdas (#1722715)
* bug fix: RUN-PROGRAM doesn't leak handles on win32 and
PROCESS-CLOSE doesn't crash. (#1724472)
- Changes in version 1.4.0
* minor incompatible change: DESTRUCTURING-BIND treats non-toplevel
() as nested empty pattern. This seems to be what the standard
mandates, so conforming code should not be affected.
* ehancement: (GC :GEN 7) with gencgc will zero-fill dead
pseudo-static objects so that they do not spuriously cause
reachability of objects that would have been otherwise dead.
* enhancement: PROCESS-STATUS now tracks stopped and continued
processes properly (also fixes #1624941, based on patch by Elias
Pipping).
* bug fix: INSPECT handles errors signaled while printing slot
values. (#454682)
* bug fix: DESCRIBE works on classes like it used to.
* bug fix: *LOAD-PATHNAME* and *LOAD-TRUENAME* are bound to
pathnames when processing a sysinit or userinit file

non-x86oid gencgc targets.
* bug fix: fixed out-of-bounds array read in optimized POSITION
on bit-vectors
* bug fix: signal emulation respects the 128-byte stack red zone
on x86-64 macOS.
* Fri Aug 11 2017 sweet_f_a@gmx.de
- Update to version 1.3.20
* minor incompatible change: DEF{GENERIC,METHOD} no longer accept
some illegal lambda lists such as (defgeneric bar (foo &key
foo)) or (defgeneric baz (t)) that were accepted before.
* optimization: a valueless &AUX binding in a BOA constructor
does not force all slots reads in safe code to perform a full
type check.
* optimization: ATOMIC-PUSH and ATOMIC-POP generate better code
* bug fix: the low-level debugger would erroneously print - or
not print as the case may be - "(bad-address)" for some objects
depending whether the --dynamic-space-size argument was used at
Lisp startup
* bug fix: a DEFCONSTANT with a non non-eql-comparable object as
the value could cause miscompilation if that constant appeared
as the default expression for an &OPTIONAL binding
* bug fix: generic function lambda lists are now checked for
repeated and otherwise illegal entries. (#1704114)
* bug fix: setting gencgc_verbose = 1 could cause deadlock in
fprintf() depending on the platform's stdio implementation. The
relevant code has been changed to use snprintf() and write()
instead.
* Tue Jul 11 2017 sweet_f_a@gmx.de
- Update to version 1.3.19
* enhancement: specialized arrays can be printed readably without using
* read-eval*
* enhancement: SB-DEBUG:PRINT-BACKTRACE truncates huge string arguments.
The full string remains available for inspection via (SB-DEBUG:ARG).

* bug fix: floating-point infinities could not be used as keys
in EQUALP hash tables. (lp#1696274)
* bug fix: random sb-fasteval failures. (lp#1642708)
* bug fix: align the stack in callback wrappers to defend against C
compiler over-aggressive use of SIMD. (lp#1697528)
* bug fix: don't try to find the class when reporting that a class does
not exist for a primitive type. (lp#1697226)
- Changes in version 1.3.18
* minor incompatible change: existing values of CFLAGS, ASFLAGS,
CPPFLAGS, and LINKFLAGS will be incorporated into C compiler
invocations when building from source.
* minor incompatible change: the result of WRITE-TO-STRING may be
a BASE-STRING if all characters written are of type BASE-CHAR.
* minor incompatible change: the broadcast stream with no output
streams is a singleton object. That object satisfies OPEN-STREAM-P
regardless of how many times CLOSE is invoked on it.
* enhancement: x86[-64] backends contain an experimental feature
which aids in demonstrating reachability of any object starting
from a tenured object or a thread stack by producing a proof
as a sequence of pointers to follow.
The file "tests/traceroot.test.sh" contains an example usage.
* enhancement: if the alien symbol "gc_coalesce_string_literals" is
set to 1 prior to SAVE-LISP-AND-DIE, then similar string constants
loaded from different fasl files may be collapsed to one object.
If the variable is set to 2, then additionally strings which are
STRING= in code resulting from COMPILE can be coalesced.
For instance, two functions returning the literal string "HI"
might return EQ strings after collapsing, which may be undesired
in a particular use. The flag pertains to gencgc only.
* enhancement: SXHASH values on pathnames are better distributed
* bug fix: MAKE-PATHNAME removes empty strings as components of a
directory, as is permitted: "Whenever a pathname is constructed
the components may be canonicalized if appropriate."
* optimization: various printer and FORMAT performance enhancements.
* bug fix: GET-FOREGROUND no longer fails in case all other interactive
threads exit (lp#1682671, reported by Syll)
* bug fix: RELEASE-FOREGROUND always removes the current thread from the
list of interactive threads. (lp#1682867, reported by Syll)
- Changes in version 1.3.17
* enhancement: memory overhead from the garbage collector's metadata
is reduced on 64-bit architectures; no change for 32-bit.
* enhancement: further garbage collector speedups affecting
pinned objects on conservative backends, and simple-vectors.
* enhancement: on Linux a custom handler for SIGSEGV can be called
for page faults outside of dynamic space by changing the C symbol
"sbcl_fallback_sigsegv_handler".
* bug fix: sb-cover does not lose source positions for AND/OR/COND.
* bug fix: random disassembler failures. (lp#1527931)
* The bundled sb-md5 contrib has been updated to release 2.0.4
which is licensed under Creative Commons CC0 per author's statement

* Tue Mar 28 2017 sweet_f_a@gmx.de
- Update to version 1.3.16
* optimization: various small tweaks give around 5% faster garbage
collection
* bug fix: better detection of when an impossible code path does
not need a warning. (lp#1668619)
* bug fix: stronger attempts to disable position-independent
executable building. (lp#1668986, patch from Mark Wright)
* bug fix: OPEN :IF-EXISTS NIL signalled a condition on Windows.
(lp#1674437, reported by Jan Idzikowski)
- Changes in version 1.3.15
* minor incompatible change: the reader will when feasible create
new symbols using a BASE-STRING for the print name. Additionally,
string literals can favor the base-string type if desired, though
the default is to always return UTF-32 strings for compatibility.
A preference for base-string does not disable reading Unicode.
The choice is controlled via (SETF READTABLE-BASE-CHAR-PREFERENCE).
If Unicode was disabled at build time, this setting does nothing.
* enhancement: SBCL generates more debug information by default.
* enhancement: type errors provide context information, such as which
variable is being bound, which slot of which structure is being set.
* enhancement: if #+immobile-symbols is in build-time *FEATURES* (not
enabled by default), then symbols will never be moved in memory
except by SAVE-LISP-AND-DIE. Immobility has helpful implications for
code generation as well as interaction with foreign routines.
This feature can only be enabled if #+immobile-space is enabled.
* enhancement: undefined function errors can be restarted on x86-64, to
either retry calling the function again or call a user supplied function.
* enhancement: sb-ext:restrict-compiler-policy accepts an upper bound in
addition to a lower bound.
* enhancement: #+immobile-code improves the speed of function calling.
Some delay may be noticed when redefining an existing function
from a saved core file however.
* defaults change: sb-ext:*disassemble-annotate* default to NIL, due to its
poor reliability.
* new feature: SB-LINKABLE-RUNTIME, allowing linking with extra object
files to help with delivery of executables. (Thanks to François-René
Rideau)
* bug fix: data race in GENTEMP fixed - it can no longer return the
same interned symbol to multiple threads if called concurrently
* bug fix: interrupting LOADing of FASLs does not leave functions without
source locations. (lp#540276)
* bug fix: DYNAMIC-EXTENT-declared results of NOTINLINE local functions were
treated as if they were actually stack allocated (lp#1659964)
* bug fix: correctly handle the case of a non-local exit within a function
terminating the extent of dynamic-extent, dynamic-bound variables in the
presence of multiple-values (lp#1655011)
* bug fix: handling of SB-SYS:WITH-PINNED-OBJECTS in the interpreters (both
sb-eval and sb-fasteval) now actually pins objects on gencgc.
* bug fix: AVX registers are preserved during exceptions on x86-64 macOS.
* bug fix: (directory "SOMETHING/*/**/MORE") is no longer equivalent to
(directory "SOMETHING/**/MORE")
* bug fix: better console IO on Windows (lp#1660906)
- rebase 0003-Add-RPM_OPT_FLAGS-to-CFLAGS-for-Linux-builds.patch
- rebase sbcl-1.1.2-install.patch
- remove sbcl-disable-frlock-test.patch
* Wed Feb 22 2017 sweet_f_a@gmx.de
- Update to version 1.3.14
* minor incompatible change: the SB-PCL walker no longer recognizes
macros expanding into a DECLARE expression. This is not a language change,
since ANSI forbids such usage (X3J13 issue DECLARE-MACROS:FLUSH).
* enhancement: for several macros such as MULTIPLE-VALUE-{BIND,SETQ}, COND,
DO{,*,LIST}, {RESTART,HANDLER}-{BIND,CASE}, *CASE, conditions signaled
during macroexpansion point to the form that caused the problem more
accurately.
* enhancement: the "--noinform" command-line option inhibits output from
save-lisp-and-die in addition to removing the startup banner.
* bug fix: PROCESS-KILL failed to return errno if the system call failed
* optimization: slightly more comprehensive treatment of the keyword
arguments to MAKE-ARRAY in compiler transformations.
- Changes in version 1.3.13
* enhancement: SET triggers package locks on undefined variables.
(lp#1645152)
* enhancement: new Windows specific option to run-program, :escape-arguments
(lp#1503496)
* enhancement: recompiling a MAKE-INSTANCE form with an initarg :INITARG
CONSTANT where CONSTANT names a constant variable picks up the new value
of CONSTANT in case it has been redefined. (lp#1644944)
* optimization: faster TYPEP on undefined at compile-time types and upcoming
class definitions. (lp#1082967)
* optimization: memory consumption of each STANDARD-OBJECT instance is
reduced by 2 words if the compact-instance-header feature is enabled.
* optimization: CONDITION instances are quicker to allocate.
* optimization: unoptimized calls to FILL on specialized vectors are now
just as fast as T vectors.
* bug fix: get-timezone returns corret DST on 64-bit Windows. (lp#1641058)
* bug fix: cross reference information in fasls is no longer incompatible
between different cores (lp#1648186)
- Changes in version 1.3.13
* enhancement: on x86-64, compiled functions loaded from fasl files
can not be moved, but can be freed, by GC. Additionally, COMPILE will
produce immobile code if SB-C::*COMPILE-TO-MEMORY-SPACE* is set to
:IMMOBILE. (Caution: the flag is experimental and subject to change.)
The benefits are better physical separation of code from data,
and potentially easier examination of live images by external tools.
* enhancement: the docstring for SAVE-LISP-AND-DIE has been amended to
say that the :ROOT-STRUCTURES parameter is not meaningless on gencgc,
depending on the platform.
* bug fix: calling a named function (e.g. a DEFUN) concurrently with
redefining that same function could lead to execution of random bytes.
* bug fix: yes-or-no-p accepts formatter functions (lp#1639490)
* bug fix: better handling of exceptions on macOS.
- rebase 0003-Add-RPM_OPT_FLAGS-to-CFLAGS-for-Linux-builds.patch
- remove sbcl-cast.patch (it's upstream now)
* Thu Nov 03 2016 sweet_f_a@gmx.de
- Update to version 1.3.11
* minor incompatible change: SB-EXT:*INTEXP-MAXIMUM-EXPONENT* is
removed.
* enhancement: TRACE ... :REPORT {TRACE,NIL} now work as
advertised in the documentation string (based on patch by
Patrick Stein)
* enhancement: support unboxed signed-word structure slots on
x86, x86-64 and ARM64. (lp#377616)
* optimization: faster logical bit-array operations on
multidimensional arrays.
* optimization: better GC performance in the presence of many
threads. (patch by Ilya Perminov, lp#1339924)
* optimization: multiple-value-call is optimized with multiple
argument forms, not just one. (lp#753803)
* bug fix: MAKE-ALIEN-STRING returns the number of allocated
bytes as a second value as advertised (reported by Johann
'Myrkraverk' Oskarsson)
* bug fix: when TO-READTABLE is supplied to COPY-READTABLE, it
will contain only the macros in FROM-READTABLE and no others.
(lp#1631506)
* enhancement: gencgc has been modified for x86-64 on Linux and
macOS to a support mark-and-sweep as well as the traditional
copying strategy. It is conceivable that some applications
might be adversely affected. Please see ':immobile-space' in
'base-target-features.lisp-expr' for further details, and
possible reasons to disable this feature.
* enhancement: x86-64 supports shrinking the fixed overhead in a
structure from 2 words to 1 word, reducing memory consumption
in applications which create many small structures.
- Changes in version 1.3.10
* enhancement: more compact low-level error signaling code
* enhancement: more compact encoding of cross-reference
information
* optimization: faster out of line fixnum-float comparisons.
* optimization: filling a known simple-vector with a constant
value is about as fast in unoptimized code as in code compiled
with (SPEED 3), and the x86-64 implementation is able to use
SSE instructions.
* bug fix: correctly handle the case of a non-local exit within a
function terminating the extent of dynamic-extent functions and
variables in the presence of multiple-values (lp#1563127)
* bug fix: restore builds on the latest OSX with the latest
Xcode (lp#1470996)
- Changes in version 1.3.9
* minor incompatible change: NAMESTRING prefers to return a
BASE-STRING instead of (ARRAY CHARACTER (*)) when possible.
* enhancement: cached make-instance/allocate-instance
constructors can now get garbage collected.
* optimization: better performance for some unoptimized
operations on complex numbers.
* bug fix: using the options :LOCAL-NICKNAMES and :LOCK in the
same DEFPACKAGE form no longer signals a bogus error
- Changes in version 1.3.8
* minor incompatible change: the system now understands that the
CONDITION type is disjoint with many other system types.
* minor incompatible change: argument types in condition report
functions are now declared (in combination with the above
change, this can result in early detection of erroneous code).
* enhancement: simple arrays of any rank can be stack-allocated
on platforms supporting stack allocation of vectors.
* optimization: improved type derivation for FIND, POSITION,
COUNT, SEARCH, MISMATCH and other array and sequence functions.
* optimization: ALLOCATE-INSTANCE is now as fast as
MAKE-INSTANCE.
* optimization: more efficient CHANGE-CLASS.
* bug fix: versions of getresuid() and getresgid() in SB-POSIX no
longer cause memory faults, and should work properly
(lp#1603806, reported by Kieran Grant)
* bug fix: handle ENOENT from getprotobyname() (lp#1596043,
reported by Stephen Hassard)
- remove upstream patches:
* 0001-Handle-ENOENT-from-getprotobyname.patch
* 0002-sb-posix-Fix-getresuid-and-getresgid.patch

+ enhancement: a new interpreter is included which has many
benefits over sb-eval. It is disabled by default. See
src/interpreter/README for instructions to enable it, and
further details.
+ enhancement: SB-THREAD support for ARM64.
+ enhancement: the platform's strtod() is exposed as
SB-POSIX:STRTOD
+ enhancement: speed up debug info creation for highly nested
functions. (#1563355)
+ enhancement: the interleaved structure slot optimization from
release 1.2.6 has been ported to all architectures.

- ExcludeArch POWER64 architecture, no POWER64 port available
* Wed Sep 30 2015 kgronlund@suse.com
- Update to version 1.2.15
+ new feature: DEPRECATION declaration for functions, variables
and types causes {EARLY,LATE,FINAL}-DEPRECATION-WARNING to be
signaled when subject of the declaration is used. Integrated
with DESCRIBE, DOCUMENTATION and
SB-CLTL2:{VARIABLE,FUNCTION}-INFORMATION. Documented in the
"Deprecation" section of the manual.
+ enhancement: ASDF updated to 3.1.5. (#1476867)
+ enhancement: definitions within PROGN get proper source
locations when compiled (needs latest Slime to take advantage
of this). (#1473147)
+ enhancement: source locations for DEFCLASS slots now point
directly to the slot definitions, not the whole DEFCLASS form.
+ bug fix: better source location in the presence of quoted
forms. (#1370561)
+ bug fix: better source locations inside backqoute. (#1361502)
+ bug fix: HANDLER-BIND requires that the handler-function be a
function designator at the time of binding establishment.
(#1480679)
+ bug fix: inlined functions surrounded by nested macrolets are
properly inlined. (#309123)
- Changes in version 1.2.14
+ minor incompatible change: The name of a compiled anonymous
lambda as returned by the third value of
FUNCTION-LAMBDA-EXPRESSION can have a lambda-list-like list
following the introductory LAMBDA that is not in general a
syntactically valid lambda list. Specifically, it won't retain
default values, supplied-p variables, or &KEY or &AUX bindings.
+ enhancement: DESTRUCTURING-BIND has been totally reimplemented
from scratch to address a handful of performance and correctness
issues. Some minor behavioral differences exist regarding order of
evaluation of default forms for unsupplied &OPTIONAL and &KEY
arguments when nested destructuring patterns are involved.
(#707556, #707573, #707578, #708051)
+ enhancement: DEFCONSTANT and DEFSTRUCT respect package locks.
(#1186238, #1036716)
+ enhancement: sb-unicode:normalize-string has a new optional
argument, FILTER, a callback which controls which decomposed
characters are collected. Useful for stripping away diacritics
more efficiently.
+ bug fix: (TYPE-OF ARRAY) for a non-simple array is subject to
change after a call of ADJUST-ARRAY. (#1333731)
+ bug fix: Dynamic-extent allocation with a loop between
allocating a value and the start of its environment no longer
discards the allocated data when the loop is taken. (#1472785)
+ bug fix: Variable-reference elimination no longer generates
incorrect code under certain circumstances. (#1446891)
+ bug fix: variables with EQL types are no longer treated as
constants by VOPs, which caused problems with closures being
allocated for such variables, but they remained unused. (#1390149)
+ bug fix: Windows installer generates registry key name
correctly. (#1476447)
* Tue Jul 14 2015 toganm@opensuse.org
- Update to version 1.2.13
* Incompatible change:
+ on success, TRY-SEMAPHORE and WAIT-ON-SEMAPHORE return the new
count
* Enhancement:
+ WAIT-ON-SEMAPHORE accepts a decrement parameter
+ JOIN-THREAD allows distinguishing timeout vs.
abort in all situations
+ On Windows DBG_PRINTEXCEPTION_C is handled and its
message is printed. (#1437947)
* Bug-fix:
+ TRUENAME works properly on broken symlinks presented
as directories. (#1458164)
+ Inlined DPB and DEPOSIT-FIELD don't interfere with
left-to-right order of argument evaluation. (#1458190)
+ (SETF (LDB (BYTE 1 2 JUNK) X) 0) is rightly rejected.
+ DEFSETF lambda lists should not permit argument
destructuring.
+ calls to (SETF SLOT-VALUE) on a missing slot would in
certain situations incorrectly return the result of a
SLOT-MISSING method instead of always returning the new
value. (#1460381)
+ a DEFMACRO occurring not at toplevel and capturing
parts of its lexical environment (thus being a closure)
caused expressions involving the macro name to cause corruption
in the pretty-printer due to faulty introspection of the lambda
list of a closure.
+ out of line MAP/MAP-INTO check that the results produced by the
function are of the matching sequence type. (#1459581)
+ pretty-printing of '(LET `((,X ,Y)) :B) is handled correctly.
* Wed Jun 17 2015 toganm@opensuse.org
- Update to version 1.2.12
* Minor incompatible change:
+ the SB-C::*POLICY* variable is no longer a list. Code which
manipulated it as such (including but not limited to non-bundled
releases of ASDF) will need to be revised.
* Enhancement:
+ The input stream for COMPILE-FILE implements STREAM-LINE-COLUMN.
+ EVAL errors that occur by way of LOAD report the starting line
and column number of the erring toplevel form. (#565247)
* Optimization:
+ Better MAP and MAP-INTO on known vector result types.
* Bug fix:
+ Read/modify/write macros accessing a place which is a composition
of CAR+CDR operations, such as (SHIFTF (CADR X) (ELT V 0)), do
not access subforms more than once. (#1450968)
+ Short form of DEFSETF no longer allows trailing junk.
+ DEFINE-MODIFY-MACRO respects the provisions of CLHS 5.1.3
regarding argument evaluation order. (#1452539)
+ POP works as specified in CLHS if the setter for its argument has
a side-effect on the existing CAR value. (#1454021)
+ Reading "#()" with a positive numeric argument signals a reader
error. As specified, reading "#1()" has undefined consequences,
so correct portable code should be indifferent to this.
(#1252100)
+ Malformed reader conditionals such as "(#-no-such-feature)"
and "(#+sbcl)" no longer parse as NIL. (#1454400)
* Sat May 02 2015 toganm@opensuse.org
- Update to version 1.2.11
* Enhancement:
+ SET-PPRINT-DISPATCH will warn when given an expression in
which any part is unrecognizable as a legal type-specifier.
The dispatch table will be altered, but the new entry is
disabled. Subsequent type-defining forms will cause
pprint-dispatch tables to re-examine whether any disabled
entries should be enabled. (lp#1429520)
+ Loading code containing calls to a deprecated function will,
under most circumstances, signal warnings similar to compiling
such code. The usual caveat holds about not detecting calls
through a computed name, as in (funcall
(intern "DEPRECATED-FUN" "SB-EXT")).
+ (SB-EXT:COMPILE-FILE-LINE) is a new macro that expands to a
constant (VALUES integer integer) indicating the source
line/column from which it was read, intended for logging Lisp
runtime errors in a style similar to that afforded by the C
preprocessor __LINE__ macro. Similarly
(SB-EXT:COMPILE-FILE-POSITION) returns a position in characters.
+ improved source locations for VOPs, alien types and declarations.
* Bug fix:
+ Functions in :FINAL deprecation have the correct docstring.
No visible change, as no such functions presently exist.
(lp#1439151)
+ (SETF (FDEFINITION this) (FDEFINITION OTHER)) signals an error
if OTHER names either a macro or special-operator. (lp#1439921)
- Rebase all patches.
* Wed Apr 01 2015 toganm@opensuse.org
- Update to version 1.2.10
* One thing that is not mentioned in the release notes, but which
has been exercising developers recently, is a warning for the near
future: some interfaces which are currently in "early" deprecation
status (and so are emitting style-warnings at compilation-time)
will in the next release cycle or two start emitting full warnings,
either at compilation time or at load time. Particular interfaces
signalling warnings causing problems to some users include:
SB-EXT:QUIT, and the SB-THREAD:SPINLOCK API. If anyone is using
those, now is the time to update to SB-EXT:EXIT and
SB-THREAD:MUTEX respectively. (See also the "Deprecated Interfaces"
chapter in the manual).
* minor incompatible change:
+ all SOCKINT::WIN32-* functions have been deprecated with
EARLY deprecation state
+ performing introspection via the system-internal SB-INT:INFO
function could expose that :TYPE :TRANSLATOR is not
necessarily a function, as it always was before. (Affects
swank-fancy-inspector)
* enhancement:
+ The value of SXHASH on bit-vectors of length equal to the
word size now depends on the vector's contents instead of
being constant; its value on bit-vectors of length divisible
by the word size now depends also on the contents of the
vector's last word.
* bug-fix:
+ sb-bsd-sockets on win32 uses proper C function declarations.
(lp#1426667)
+ A new dead code elimination phase removes dead code loops
that confuse stack analysis. (lp#1255782, lp#308914)
+ A toplevel form which was simple enough to bypass the main
compiler in COMPILE-FILE, and which contained an empty SETQ or
PROGN would produce an invalid fasl file. (lp#1427050)
+ The compiler no longer signals an internal error when
encountering invalid FUNCTION forms like (function 1)
+ express proper dependencies in the ASDF contrib, to support
systems where make runs in parallel. (lp#1434768; thanks to
Nikhil Benesch)
- Apply disable-localport-bsd-sockets-test.patch for all since
without it random build failures are happening in OBS even though
local builds are just fine without disabling the bsd-socket-tests
* Sat Feb 28 2015 toganm@opensuse.org
- Update to version 1.2.9
* Bug Fix:
+ minor incompatible change and bug fix: unboxed numeric
constants on x86oids are arranged in memory differently, and
the disassembler does not show them separately in DISASSEMBLE,
but does if DISASSEMBLE-CODE-COMPONENT is used. (lp#1421987)
+ DEFCLASS handles cyclic {super,meta}class relations better
(lp#1418883)
+ compiler no longer signals an error when compiling certain
function calls. (lp#1416704, lp#404441, lp#1417822, lp#1234919)
+ compiler doesn't stumble on a LOGIOR transform.
(lp#1389433)
+ more robust debugger and backtraces. (lp#1413850,
lp#1099500, lp#1412881, lp#945261, lp#1419205, lp#1409402)
+ files larger than 4GB can now be compiled.
+ x86 truncated results from 64-bit foreign functions to
32 bits.
+ file-position didn't work on large files on win32.
(lp#1271545)
+ callbacks from foreign threads can work without enabling
sb-safepoint.
+ sb-introspect:function-lambda-list works properly on
interpeted macros. (lp#1387404)
+ ADJUST-ARRAY properly handles non-adjustable arrays.
(lp#886418)
+ compiler no longer fails to dump a multidimensional
array constant involving a circular reference to itself
+ conditional and nested DX allocation no longer confuse
the compiler in STACK analysis. (lp#1044465)
+ sb-rotate-byte constant folding bug fixed. (lp#1423682)
* Optimization:
+ The compiler's treatment of type specifiers makes
it slightly faster and more memory-efficient. Portable code
should be indifferent to this change, however, users of
SB-INTROSPECT:FUNCTION-TYPE might notice that (MEMBER T NIL)
and (MEMBER NIL T) are both internally collapsed to the former,
so that the latter can never be obtained as part of an FTYPE.
+ a TYPEP call in which the second argument is not
a QUOTE form but nevertheless recognized as a compile-time
constant might open-code the test. One scenario for this involves
backquote, such as (TYPEP x `(my-type ,some-arg)). Code which relied upon
deferring until runtime should declare (NOTINLINE TYPEP).
[Due to the sematic constraints of DEFTYPE etc in in CLHS
3.2.2.3, code requiring delayed evaluation could be unportable though.]
* Enhancement:
+ unused variables at the top-level are now reported.
(lp#492200)
* Mon Feb 02 2015 toganm@opensuse.org
- The release (source) tarball of sbcl-1.2.8 contained an error in
the build script, which in some circumstances (chiefly when /bin/sh is
bash) would lead to the sbcl built from that tarball to have a
lisp-implementation-version of "-dirty".
* Sat Jan 31 2015 toganm@opensuse.org
- Update to version 1.2.8
* Enhancement:
+better error and warning messages. (lp#1314767,
lp#736383)
+ backtrace for invalid argument count produces the
exact supplied arguments including the extra ones, on x86,
x86-64 and ARM.
+ STYLE-WARNING is signaled for DEFSTRUCT accessors which
are used before the structure is defined; similarly for the
predicate.
* Optimization
+ FORMAT NIL with only ~a and string arguments is transformed
into CONCATENATE.
+ POSITION and FIND when inlined into code that is compiled
with qualities of safety < 2 and speed > space will no longer
signal an error on circular lists, but will potentially loop
forever if given no :END constraint. As was always the case,
calls that are not inlined are safe regardless of lexical
policy.
* Bug Fix:
+ CLOS methods compiled with (OPTIMIZE (DEBUG 0))no longer
cause debugger failure when printing a backtrace
+ more resilience to deleted code. (lp#1308328, lp#1390544)
+ the CLHS example of MAKE-LOAD-FORM involving TREE-WITH-PARENT
did not work, and now it does.
* Thu Jan 08 2015 toganm@opensuse.org
- Update to version 1.2.7
* Optimization:
+ returning constant values refers to preboxed
constants more reliably. (lp#1398785)
* Enhancement:
+ STYLE-WARNING is produced if a compiler-macro is
defined for a function after at least one ordinary (not inlined)
call to that function was compiled, indicating a likely
compilation order problem. Likewise a warning ensues if a call
is compiled to a function that is subsequently proclaimed INLINE.
+ always lose() when something goes wrong while saving a core
(instead of just printing an error on stderr in some situations).
+ frames in the debugger are now restartable by default.
* Bug Fix:
+ restore error handling on Windows x86.
+ MAKE-SEQUENCE detects type errors in its :INITIAL-ELEMENT
at compile-time when possible. (lp#330299)
+ parsing of malformed type specifiers no longer results in a
memory-fault-error.
+ LOOP properly destructures nested lists in WITH.
+ MACROEXPANDing the redefinition of an alien structure type no
longer signals the wrong error.
+ PROGV doesn't get confused by forced DEBUG 3 (lp#1405456).
* Tue Dec 02 2014 toganm@opensuse.org
- Update to version 1.2.6
* enhancement:
+ SERVE-EVENTS uses the poll() system call in lieu
of select() if the OS has the former. Previously poll() was
used only if waiting on exactly one file descriptor.
+ efficiency of access to untagged structure slots
is improved on x86-64, and the order of slots in memory is
exactly as specified by defstruct, simplifying use of
structures as arguments to foreign calls.
* bug fix:
+ SB-DEBUG:ARG now works in all TRACE options which
evaluate forms. (lp#1357826)
+ GC memory corruption during internal memory handling.
+ duplicate effective-slot-definition objects as compared
by EQ on name could be present in CLASS-SLOTS of a class whose
metaclass was structure-class or condition-class. (lp#1049423)
+ HANDLER-BIND with empty bindings works again; regression in
1.2.5. (lp#1388707)
+ ATOMIC-INCF works on structure slots in interpreted code.
(lp#1381867)
+ MAKE-ARRAY properly handles character types like (eql
[#]\a) and (member #\a #\c). (lp#1392068)
+ bug fix: READ sometimes accidentally preserved a whitespace
character after a token when it should not have. (lp#327790)
* Wed Nov 05 2014 schwab@suse.de
- 0002-Fix-array-bound-checking-with-negative-indexes-on-AR.patch: remove
obsolete patch
* Wed Nov 05 2014 toganm@opensuse.org
- Update to version 1.2.5
* Enhancement
+ sb-bsd-sockets now has basic support for IPv6
+ An sb-unicode package has been added, containing
many functions related to handling Unicode text
+ The reader now normalizes symbols to Normalization
Form KC (NFKC). This behavior can be disabled with
SB-EXT:READTABLE-NORMALIZATION
+ enhancement: a style-warning is signaled if OPTIMIZE
declarations multiply specify a quality with differing values.
(lp#310267)
* Bug fix:
+ conservatively pointed to pages wipe out unused dwords
so that they cannot act as false roots in turn.
+ the walker's handling of lexical variable and
symbol-macro bindings is improved (lp#375326, lp#1368305)
+ HANDLER-{BIND,CASE} no longer drop into ldb when a
clause contains an undefined condition type; regression
in 1.1.19( lp#1378939)
+ in interpreted code, inequality predicates did not
type-check arguments that weren't examined, and a 1-argument use
of MIN or MAX accepted a complex number. (lp#1373702)
+ APROPOS and APROPOS-LIST handle inherited symbols correctly.
(lp#1364413, thanks to Zach Beane)
