* incompatible change: HPPA and DEC Alpha architecture support has been removed.
* minor incompatible change: the compiler signals a warning at compile-time when an initform of T, NIL or 0 does not match a STANDARD-CLASS slot\'s declared type.
* minor incompatible change: the runtime no longer uses SIGPIPE internally, so the signal is deliverable to user code as is customary. Ignoring the signal - in lieu of the OS default of process termination - is obtainable via (SB-SYS:ENABLE-INTERRUPT SB-UNIX:SIGPIPE :IGNORE).
* platform support:

*
* 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.

* 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: 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 - 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)

* Fri Mar 13 2020 John Paul Adrian Glaubitz - 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 - 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 - 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.
*

*
* 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.

* 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 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)- Changes in 1.5.8

* 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)
* bug fix: pattern pieces in pathname components are correctly escaped during unparsing.
* bug fix: DELETE-DIRECTORY no longer signals an error when the directory is supplied as a pathname with name and/or type components containing escaped characters. (#1740624)
* bug fix: weak hash-tables no longer cause GC time to scale superlinearly (#1241771)
* bug fix: CANCEL-FINALIZATION operates in approximately constant time per operation (#1587983)
* bug fix: big-endian MIPS systems now (mostly) work again (broken since 1.3.14.x).
* 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: fixed heap exhaustion bug when consing millions of small objects
* 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)
* bug fix: memory faults from lisp no longer use (thread-and-interrupt unsafe) 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_aAATTgmx.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
* bug fix: save-lisp-and-die is able to collect more garbage on 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_aAATTgmx.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_aAATTgmx.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: backtracing from several threads at once could fail
* 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 https://github.com/pmai/md5/commit/fd134e71b71a10ab78905833a7cb9d4d6817c589 (Refer to NEWS and COPYING in the contrib/sb-md5 subdirectory)- add fix-tests.patch, bnc#1041271- rebase 0003-Add-RPM_OPT_FLAGS-to-CFLAGS-for-Linux-builds.patch
* Sun May 07 2017 meissnerAATTsuse.com- Added #!BuildIgnore gcc-PIE to make it build in the Global PIE support project.- move info deinstall from %postun to %preun
* Tue Mar 28 2017 sweet_f_aAATTgmx.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_aAATTgmx.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_aAATTgmx.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- rebase 0003-Add-RPM_OPT_FLAGS-to-CFLAGS-for-Linux-builds.patch
* Wed Oct 19 2016 sweet_f_aAATTgmx.de- always build with clisp, no bootstrapping required
* Sun Jul 24 2016 kgronlundAATTsuse.com- Update to version 1.3.7 + enhancement: ported to ARM64 Linux. + 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.- Add $(RPM_OPT_FLAGS) to CFLAGS for Linux builds- Handle ENOENT from getprotobyname()- sb-posix: Fix getresuid() and getresgid()- Remove sbcl-1.1.17-optflags.patch- Add 0001-Handle-ENOENT-from-getprotobyname.patch- Add 0002-sb-posix-Fix-getresuid-and-getresgid.patch- Add 0003-Add-RPM_OPT_FLAGS-to-CFLAGS-for-Linux-builds.patch
* Mon Mar 28 2016 dvaleevAATTsuse.com- ExcludeArch POWER64 architecture, no POWER64 port available
* Wed Sep 30 2015 kgronlundAATTsuse.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 toganmAATTopensuse.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 toganmAATTopensuse.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 toganmAATTopensuse.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 toganmAATTopensuse.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 toganmAATTopensuse.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 toganmAATTopensuse.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 toganmAATTopensuse.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 toganmAATTopensuse.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 toganmAATTopensuse.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 schwabAATTsuse.de- 0002-Fix-array-bound-checking-with-negative-indexes-on-AR.patch: remove obsolete patch
* Wed Nov 05 2014 toganmAATTopensuse.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)
