    6d26ba97 · 0.9.16: · 
    changes in sbcl-0.9.16 relative to sbcl-0.9.15:
  * feature: implemented the READER-METHOD-CLASS and
    WRITER-METHOD-CLASS portion of the Class Initialization Protocol
    as specified by AMOP.
  * incompatible change: variable SB-EXT:*USE-IMPLEMENTATION-TYPES*
    no longer exists.
  * optimization: faster LOGCOUNT implementation on x86 and x86-64
    (thanks to Lutz Euler)
  * optimization: hashing of general arrays and vectors has been
    improved. (reported by Any Fingerhut)
  * enhancement: SB-INTROSPECT is now able to find definitions of
    profiled functions. (thanks to Troels Henriksen)
  * enhancement: compiler-macro expansion applies now to FUNCALL forms
    as well, allowing compiler-macros for SETF-functions to expand.
  * enhancement: step-instrumentation no longer wraps known
    single-value functions with multiple-value context, allowing
    better type inference.
  * fixed bug #337: use of MAKE-METHOD in method combination now works
    even in the presence of user-defined method classes.  (reported by
    Bruno Haible and Pascal Costanza)
  * fixed bug #339(c): if there are applicable methods not part of any
    long-form method-combination group, call INVALID-METHOD-ERROR.
    (reported by Bruno Haible)
  * fixed bug #361: the :FUNCTION initarg in the protocol for
    initialization of methods can now be used to override
    internally-produced optimized functions.  (reported by Bruno
    Haible)
  * bug fix: extensions of MAKE-METHOD-LAMBDA which wrap the
    system-provided lambda expression no longer cause warnings about
    unbound #:|pv-table| symbols.
  * bug fix: improved the handling of type declarations and the
    detection of violations for keyword arguments with non-constant
    defaults.
  * bug fix: potentially erronous calls to PATHNAME and
    MERGE-PATHNAMES were being flushed in some cases.
    (reported by Richard Kreuter)
  * bug fix: compiled calls to TYPEP were mishandling obsolete
    instances.  (reported by James Bielman and Attila Lendvai)
  * bug fix: format strings with ~> without matching ~< no longer
    trigger an AVER, but signal an understandable error instead.
    (reported by Antonio Martinez)
  * bug fix: specifying an output-file without a pathname-type for
    COMPILE-FILE or COMPILE-FILE-PATHNAME resulted in using the type
    of input-file instead of "fasl". (reported by Robert Dodier)
  * bug fix: compiler-macro lambda-list parsing of FUNCALL forms.
    (reported by James Y Knight).
  * bug fix: compiler-macros-function did not consider the environment
    argument for shadowing by local functions.
  * bug fix: compiler-macros expansion was inhibited by local INLINE
    declarations.
  * bug fix: inline expansions of known functions were subject to
    step-instrumentation in high debug policies, leading to problems
    with type-inference.
  * bug fix: compiler failed to differentiate between different CONS
    types in some cases.
  * bug fix: fixed input, output and error redirection in RUN-PROGRAM
    for win32. (thanks to Mike Thomas and Yaroslav Kavenchuk)
  * bug fix: #368: incorrect use of expressed vs. upgraded array
    element type.
  * bug fix: #306a: more precise unions of array types.
  * thread-safety improvements:
    ** CONDITION-WAIT could return early on Linux, if the thread was
       interrupted and subsequently continued with SIGCONT.
    ** STABLE-SORT and ADJUST-ARRAY were not reentrant.

  • sbcl_0_9_14

    02e900a3 · 0.9.14: · 
    changes in sbcl-0.9.14 relative to sbcl-0.9.13:
  * feature: thread support on Solaris/x86, and experimental thread support
    on OS X/x86.
  * feature: SBCL now tries to signal a STORAGE-CONDITION when running out
    of heap.
  * feature: SBCL now provides USE-VALUE and STORE-VALUE restarts in the
    default method for SLOT-UNBOUND.
  * minor incompatible change: prevent the user from specializing the
    new-value argument to SB-MOP:SLOT-VALUE-USING-CLASS.  It's
    somewhat counter to the intent of the protocol, I (CSR) think, and
    additionally it just doesn't work in SBCL as currently
    implemented, thanks to optimizations (that are always valid for
    the other three SLOT-VALUEish functions, but not for the setter).
  * minor incompatible change: the :SB-LDB feature is now enabled by
    default, and DISABLE-DEBUGGER and ENABLE-DEBUGGER also affect
    the low-level debugger.
  * enchancement: RUN-PROGRAM is now able to extract the file-descriptor
    from SYNONYM-STREAM and TWO-WAY-STREAM provided they can be decomposed
    down to an SB-SYS:FD-STREAM, allowing direct communication in
    more cases. Temporary files and pipes are still used as a fallback
    strategy.
  * thread-safety: DECODE-UNIVERSAL-TIME & GET-DECODED-TIME depended
    on the non-reentrant C functions localtime(3) and gmtime(3).
  * bug fix: global optimization policy was not visible in LOCALLY and
    MACROLET forms.
  * bug fix: class objects can be used as specializers in methods.
    (reported by Pascal Costanza)
  * bug fix: native unparsing of pathnames with :DIRECTORY NIL failed
    with a type error. (reported by blitz_ on #lisp)
  * bug fix: unparsing logical pathnames with :NAME :WILD :TYPE NIL
    failed with a type error.  (reported by Pascal Bourguignon)
  * bug fix: merging pathnames against defaults with :DIRECTORY
    starting with '(:RELATIVE :BACK) should preserve the :BACK.
    (reported by James Y Knight)
  * bug fix: saving large (>2GB) cores on x86-64 now works
  * bug fix: a x86-64 backend bug when compiling (setf aref) with a
    constant index and a (simple-array (signed-byte 32)) array
  * bug fix: NAME-CHAR on an invalid symbol no longer signals an
    error (patch by Robert J. Macomber)
  * feature: TIME now displays the amount of run-time spent in GC
  * bug fix: The debugger now does a better job of respecting
    (PUSH '(*PRINT-CIRCLE* . T) SB-DEBUG:*DEBUG-PRINT-VARIABLE-ALIST*)
    when printing SB-DEBUG:*DEBUG-CONDITION*. (This is a debugger-only
    workaround for bug 403.)
  * bug fix: floating point exception handling now works on FreeBSD
    (thanks to NIIMI Satoshi)
  * fixed some bugs revealed by Paul Dietz' test suite:
    ** MISC.641: LET-conversion were not supposed to work in late
       compilation stages.
  * improvements to the Win32/x86 port:
    ** GET-INTERNAL-RUN-TIME implemented, thanks to Frank Buss.
    ** improved SB-BSD-SOCKETS support, thanks to Timothy Ritchey.

  • sbcl_0_9_13

    fcd29061 · 0.9.13: · 
    changes in sbcl-0.9.13 relative to sbcl-0.9.12:
  * new feature: source path information is generated for macro-expansion
    errors for use in IDE's like Slime (thanks to Helmut Eller)
  * bug fix: calls to the compiler no longer modify *RANDOM-STATE*
  * bug fix: compiler does not loop forever on an invalid type in
    TYPEP.
  * improvement: compilation of most CLOS applications is significantly
    faster
  * optimization: added a limited bytecode compiler for simple toplevel
    forms, speeding up compilation and FASL loading
  * bug fix: the statistical profiler now properly distinguishes anonymous
    functions

  • sbcl_0_9_11

    2e3a763d · 0.9.11: · 
    changes in sbcl-0.9.11 relative to sbcl-0.9.10:
  * new platform: experimental support for SBCL x86/Darwin, including
    MacOS X 10.4.5 on Intel.
  * new feature: Unicode character names are now known to the system
    (through CHAR-NAME and NAME-CHAR).
  * new feature: the filesystem location of SBCL's core file is
    exposed to lisp through the variable SB-EXT:*CORE-PATHNAME*.
  * minor incompatible change: the contrib modules SB-POSIX and
    SB-BSD-SOCKETS no longer depend on stub C libraries; the intent of
    this change is to make it easier to distribute
    location-independent binaries.
  * bug fix: as implied by AMOP, standardized classes no longer have
    slots named by external symbols of public packages.  (reported by
    Pascal Costanza)
  * optimization: calling functions via constant symbols -- as in
    (FUNCALL 'FOO) -- is now roughly as efficient as calling them
    via the function object as in (FUNCALL #'FOO).
  * optimization: on x86 and x86-64, the calling convention for the
    case of dealing with an unknown number of values has been altered
    to be friendlier to the prediction heuristics implemented,
    particularly with reference to CALL and RET pairing.  (thanks to
    Alastair Bridgewater)
  * optimization: on x86, the code for access to thread-local symbol
    values and binding/unbinding of thread-local symbols is smaller.
    (thanks to Alastair Bridgewater)
  * enhancement: CONSTANTP is now able to determine constantness of
    more complex forms, including calls to constant-foldable standardized
    functions and some special forms beyond QUOTE.
  * fixed bug: occasional GC crashes on Solaris/x86
  * optimization: x86-64 supports stack allocation of results of simple
    calls of MAKE-ARRAY, bound to variables, declared DYNAMIC-EXTENT
  * enchancement: the PROCESS-INPUT and -OUTPUT streams created by
    SB-EXT:RUN-PROGRAM can be used for both character and byte IO
    (thanks to James Knight)
  * fixed bug: CL:LISTEN always returns NIL at end of file, as required
    by the standard (thanks to Stephen Compall)

  • sbcl_0_9_10

    98329126 · 0.9.10: · 
    changes in sbcl-0.9.10 relative to sbcl-0.9.9:
  * new feature: new SAVE-LISP-AND-DIE keyword argument :EXECUTABLE can
    be used for bundling the runtime and the core file into one
    executable binary. This feature is not currently supported on all SBCL
    platforms.  (thanks to James Bielman and NIIMI Satoshi)
  * new feature: a generational or ephemeral garbage collector is now
    the default on the PowerPC platform (both Linux and Darwin).  The
    old Cheney (stop and copy) collector is a build-time option.
    (thanks to Cyrus Harmon, after Raymond Toy)
  * minor incompatible change: the method by which SBCL finds its
    contributed modules has changed; it no longer relies on symbolic
    links from an $SBCL_HOME/systems directory, but searches directly
    in the subdirectories of $SBCL_HOME.
  * enhancement: the dynamic heap size on the Linux/PPC platform is
    markedly larger, even using the older Cheney garbage collector.
  * fixed bug #399: full call to DATA-VECTOR-REF in accesses to
    certain complicated string types.  (reported by Gary King)
  * fixed bug: STRING-TO-OCTETS and OCTETS-TO-STRING did not convert
    character codes.  (thanks to Yaroslav Kavenchuk and Ivan Boldyrev)
  * fixed bug: DOCUMENTATION on structures no longer signals an
    error if no structure type of the right name exists.  (reported by
    Glenn Ehrlich)
  * fixed bug: compiled calls to MAKE-INSTANCE where there is an
    applicable non-standard primary or :AROUND method on
    INITIALIZE-INSTANCE or SHARED-INITIALIZE and a non-keyword initarg
    no longer cause unbound variable errors.  (reported by Kevin Reid)
  * fixed bug: metacircle resolution in cases where methods have slots
    added before the slots from STANDARD-METHOD.  (reported by Jean
    Bresson)
  * fixed bug: the Power PC assembly code for calling into lisp
    sometimes computed its return address wrongly (depending on the
    15th bit of the address, fixed at link time).  This used to
    manifest itself in a segmentation violation while building PCL.
    (reported by Kevin Rosenberg, Eric Marsden, Lars Brinkhoff and
    many others over the years)
  * fixed bug: ROOM no longer reports silly numbers for stack usage if
    the stack pointer (treated as a signed integer) is negative.
    (thanks to Peter van Eynde)

  • sbcl_0_9_9

    8464b733 · 0.9.9: · 
    changes in sbcl-0.9.9 relative to sbcl-0.9.8:
  * new platform: experimental support for the Windows operating
    system has been added.  (thanks to Alastair Bridgewater)

    callbacks).  (thanks to Cyrus Harmon and Heiner Schwarte)
  * bug fix: allow non-simple string symbol names (reported by Paul
    Dietz)
  * bug fix: interrupt handling on NetBSD (thanks to Richard M
    Kreuter)
  * bug fix: saving a core corrupted callbacks on x86/x86-64
  * bug fix: closed a loophole in metacircularity detection and
    grounding in the PCL implementation of CLOS.
  * bug fix: TRUENAME on "/" no longer returns a relative pathname.
    (reported by tomppa on #lisp)
  * bug fix: clear the direction flag on Lisp -> C transitions, as
    required by the x86-64 ABI. Fixes mysterious GC crashes on SuSE.
    (reported by Andrej Grozin and Hendrik Maryns)
  * optimization: major improvements to GC efficiency on GENCGC platforms
  * optimization: faster implementation of EQUAL
  * optimization: emit more efficient opcodes for some common
    immediate->register MOV instructions on x86-64.  (thanks to Lutz Euler)
  * optimization: several other minor code-generation improvements on x86-64
  * fixed segfaults on x86 FreeBSD 7-current.  (thanks to NIIMI Satoshi)

  • sbcl_0_9_8

    242bb933 · 0.9.8: · 
    changes in sbcl-0.9.8 relative to sbcl-0.9.7:
  * minor incompatible change: (SETF CLASS-NAME) and (SETF
    GENERIC-FUNCTION-NAME) are generic functions once more (reverting
    the change in the 0.9.7 release).  (SETF CLASS-NAME) is specified
    by ANSI as a generic function, and for consistency (SETF
    GENERIC-FUNCTION-NAME) is treated likewise.
  * fixed bug #233.b: make constraint propagation notice when a variable
    value is changed after it is referenced but before it is used
  * fixed bug #296: no more arbitrary behaviour from filenames with
    odd characters as --load arguments.  (reported by Adam Warner)
  * fixed bug #390: :CHARACTER-SET pathname components now work as
    expected.  (reported by Tim Daly Jr)
  * fixed bug #391: complicated :TYPE intersections in slot
    definitions no longer cause an error in PCL internals.
  * fixed bug #392: plugged a hole in the obsolete-instance protocol.
  * bug fix: FILE-STRING-LENGTH is now external-format sensitive,
    returning the number of octets which would be written to the
    file-stream.  (thanks to Robert J. Macomber)
  * bug fix: the SB-SIMPLE-STREAMS contrib passes external-format
    arguments to the internal stream functions.  (thanks to David
    Lichteblau)
  * bug fix: stack exhaustion is now handled on the x86/SunOS
    platform.  (thanks to Daisuke Homma)
  * bug fix: more accurate ROOM results on GENCGC platforms
  * optimization: improved type inference for arithmetic-for
    index variables in LOOP
  * optimization: faster floating-point SQRT on x86-64
  * fixed some bugs revealed by Paul Dietz' test suite:
    ** DOCUMENTATION returns NIL instead of "" for method combinations
       that don't have a docstring


  • sbcl_0_9_7

    433a2459 · 0.9.7: · 
    changes in sbcl-0.9.7 relative to sbcl-0.9.6:
  * minor incompatible change: (SETF CLASS-NAME) and (SETF
    GENERIC-FUNCTION-NAME) are no longer generic functions, and
    therefore are not customizeable by user code (as seems to be at
    least permitted and maybe required by AMOP).  As a consolation,
    however, the SBCL implementation of these functions now calls
    REINITIALIZE-INSTANCE as specified by AMOP.
  * bug fix: slot-definition documentation is propagated as per ANSI
    7.6.2 to EFFECTIVE-SLOT-DEFINITIONS.
    COMPUTE-EFFECTIVE-SLOT-DEFINITION now receives a :DOCUMENTATION
    argument, as do eslotd initialization methods.  (from Pascal
    Costanza's "Closer" project)
  * bug fix: REINITIALIZE-INSTANCE on generic functions calls
    COMPUTE-DISCRIMINATING-FUNCTION (almost) unconditionally, as
    specified by AMOP.
  * bug fix: it is now possible to have more than one subclass of
    STANDARD-GENERIC-FUNCTION without causing stack overflow.
    (reported by Bruno Haible, Pascal Costanza and others)
  * bug fix: the dependent update protocol now works for generic
    functions.  (thanks to Gerd Moellmann; reported by Bruno Haible
    and Pascal Costanza)
  * bug fix: condition-class instances corresponding to
    DEFINE-CONDITION forms are now created eagerly.  (reported by
    Kalle Olavi Niemitalo on comp.lang.lisp)
  * bug fix: floating point printing is more accurate in some
    circumstances.  (thanks to Simon Alexander)
  * bug fix: *COMPILE-FILE-PATHNAME* now contains the user's pathname
    merged with *DEFAULT-PATHNAME-DEFAULTS*.
  * bug fix: callbacks on OS X now preserve stack-alignment.
    (thanks to Cyrus Harmon)
  * enhancement: the x86-64 disassembler is much better at
    disassembling SSE instructions.  (thanks to Lutz Euler)
  * enhancement: CHECK-TYPE on a variable now allows type-inference
    (thanks to Vincent Arkesteijn)
  * optimization: improved performance of EUC-JP external format.
    (thanks to NIIMI Satoshi)
  * optimization: performance improvements to IO on file streams of
    :ELEMENT-TYPE CHARACTER
  * optimization: much faster memory allocation on x86-64
  * optimization: faster garbage collections (latency and throughput)
    on gencgc
  * optimization: faster bignum subtraction and division on x86 and x86-64
    (thanks to Lutz Euler)

    Linux kernels with apparently buggy implementations of personality().
    (thanks to Svein Ove Aas)
  * bug fix: Unicode symbols are correctly printed in LDB backtraces
    (thanks to David Lichteblau)
  * bug fix: local bindings shadow global symbol macros for
    macroexpansion.  (reported by Matthew D Swank on comp.lang.lisp)
  * optimization: non-open coded uses of numeric comparison operators
    (e.g. >) no longer cons when called with more than one parameter
    on platforms supporting dynamic-extent allocation.
  * enhancement: saving cores with foreign code loaded is now supported
    on MIPS/Linux in addition to the previously supported platforms.
  * bug fix: FIND-RESTART now tests for activity, not applicability when given
    a restart object as identifier. (reported by Helmut Eller for CMUCL)
  * bug fix: division by zero in sb-sprof when no samples were collected
  * bug fix: a race when a slow to arrive sigprof signal killed sbcl
  * bug fix: asdf-install uses CRLF as required by the HTTP spec.
    (thanks to Alexander Kjeldaas)
  * new feature: ignoring the return values of destructive functions
    like NREVERSE signals a compile-time style-warning.
    (thanks to Kevin Reid)

    explicitly specified. (thanks to Cyrus Harmon)
  * bug fix: run cleanup forms (in all threads) when receiving a SIGTERM
    and dump core on SIGQUIT
  * threads
    ** incompatible change: threads do not inherit values of specials
       from their parents (see manual)
    ** bug fix: threads stacks belonging to dead threads are freed by the
       next exiting thread, no need to gc to collect thread stacks anymore
    ** minor incompatible change: INTERRUPT-THREAD-ERROR-ERRNO removed
    ** WITH-RECURSIVE-LOCK can be nested in a WITH-MUTEX for the same lock
    ** bug fix: dynamic variable and thread start related gc lossage
    ** bug fix: job control (SIGSTOP/SIGCONT) no longer confuses threads
       suspended for gc
  * fixed some bugs revealed by Paul Dietz' test suite:
    ** SUBTYPEP is slightly more accurate on heinously complicated
       CONS types where some of the members have uncertain (in the
       NIL, NIL sense) type relationships to each other.
  * GENCGC
    ** Cores produced by SAVE-LISP-AND-DIE on GENCGC platforms are
       no longer purified unless :PURIFY T is explicitly specified.
    ** Non-purified cores are significantly smaller than before

  * incompatible change: a threaded SBCL will no longer revert to
    non-threaded mode on non-NPTL systems, but refuse to start entirely.
  * bug fix: interrupts are disabled until startup is complete; no
    more sigsegvs when receiving a signal to soon
  * optimization: faster 32-bit SB-ROTATE-BYTE:ROTATE-BYTE on non-x86/ppc
    platforms
  * bug fix: add a workaround for the memory randomization features in
    Linux kernels >= 2.6.12 that interfere with SBCL's memory maps. This
    workaround will only be in effect on systems with the proc filesystem
    mounted.
  * bug fix: printing objects of type HASH-TABLE signals a
    PRINT-NOT-READABLE error when *READ-EVAL* is NIL.  (reported by
    Faré Rideau)
  * bug fix: GET-INTERNAL-REAL-TIME now works even for processes that
    have been running for over 50 days. (reported by Gilbert Baumann)
  * bug fix: the logic for getting names of functions gets less
    confused when confronded with alternate-metaclass
    funcallable-instances.  (reported by Cyrus Harmon)
  * bug fix: FUNCTIONP and (LAMBDA (X) (TYPEP X 'FUNCTION)) are now
    consistent, even on internal alternate-metaclass objects.
  * bug fix: flush closure information collected by physical
    environment analysis prepass before the main pass. (bug reported
    by Vasile Rotaru)
  * bug fix: compiler pack phase does not modify a hashtable, which is
    iterated. (reported by Bryan O'Connor, fixed by Rob MacLachlan)
  * bug fix: backquote does not optimize (LIST* x y) to CONS when x
    may be expanded. (reported by Alexander <malishev> on c.l.l)
  * bug fix: no more style-warnings when compiling code using LAST
    under high-SPEED low-SPACE settings.  (reported by David Wallin
    aka froog on #lisp)
  * fixed some incompatibilities between SBCL's MOP and the MOP
    specified by AMOP:
    ** the METAOBJECT class is now implemented;
    ** FUNCALLABLE-STANDARD-OBJECT is now a subclass of
       STANDARD-OBJECT, as required;
    ** the classes STANDARD-CLASS and FUNCALLABLE-STANDARD-CLASS are
       now compatible (as required by VALIDATE-SUPERCLASS); there
       remains a consistency requirement over the presence or absence
       of the FUNCTION class in the superclass list of finalized
       classes; see the manual for more details;
    ** the :AROUND method for COMPUTE-SLOTS on
       FUNCALLABLE-STANDARD-CLASS now honours the primary method's

  * threads
    ** bug fix: parent thread now can be gc'ed even with a live

       Hannu Koivisto)
    ** bug fix: binding specials is thread safe (thanks to
       Hannu Koivisto)
    ** bug fix: interrupt handlers are now per-process, RUN-PROGRAM

       cell.
    ** DISASSEMBLE now throws a TYPE-ERROR when its argument does not

    restart associated with it, not TOPLEVEL and ABORT as it used to.
    TOP and TOPLEVEL are now available as debugger commands for
    returning to the top level.
  * incompatible change: forms evaluated in the REPL now use the
    global optimization policy.
  * incompatible change: user- and system-initialization files are
    no longer processed with LOAD, but by READ and EVAL; hence the
    global optimization policy, startup package, readtable, etc,

  * The .fasl file format number has been incremented because of
    various incompatible changes.
  * internal entry point details and argument counts no longer appear

    write to mprotect()ed memory (SIGSEGV on Linux and some *BSDs,
    SIGBUS on other *BSDs) on architectures where the C stack is also
    the Lisp stack (x86 and x86-64) from foreign code no longer leads
    to debugger confusion or wild instability.  (reported by Cheuksan

    notes when operating on objects known to be SIMPLE-BIT-VECTORs.
    (reported by Lutz Euler)
  * fixed bug: (TYPEP X '(MEMBER ...)) no longer returns a list in
    compiled code. (reported by Paul Dietz)

    specialized parameter to a method to something that is not TYPEP
    the specializer is now possible.

  * contrib improvement: the SB-SIMPLE-STREAMS contrib now defines
    STRING-SIMPLE-STREAM and FILE-SIMPLE-STREAM as subclasses of

       character-based file input are correctly transferred to the
       start of the buffer at the next read.
    ** COMPILE-FILE now respects any EXTERNAL-FORMAT argument given,
       passing it through to OPEN.
    ** LOAD on source files likewise passes any EXTERNAL-FORMAT
       argument given to internal calls to OPEN.
    ** the built-in comment readers (introduced by character sequences

    generic functions in other (locked) packages no longer signals
    bogus package lock violations. (reported by François-René Rideau)
  * bug fix: special variables as DEFMETHOD parameters no longer have
    associated bogus type declarations. (reported by David Wragg and
    Bruno Haible)
  * bug fix: read-write consistency on streams of element-type
    (SIGNED-BYTE N) for N > 32.  (reported by Bruno Haible for CMUCL)
  * bug fix: redefiniton of the only method of a generic function with
    no DEFGENERIC no longer emits a full WARNING.  In addition,
    redefinition of generic functions with no DEFGENERIC to an
    incompatible lambda list now signals an error.  (thanks to Zach
    Beane)
  * bug fix: DEFGENERIC now works even when there's a function of the
    same name in an enclosing lexical environment.  (thanks to Zach
    Beane)
  * fixed compiler failure, caused by instrumenting code during
    IR1-optimization.  (Debian bug report #273606 by Gabor Melis)
  * optimization: added loop analysis and improved register allocation
  * fixed some bugs revealed by Paul Dietz' test suite:
    ** POSITION on displaced vectors with non-zero displacement
       returns the right answer.
    ** (SIMPLE-STRING) is a valid type specifier for sequence
       creators.
    ** *PRINT-LEVEL* handling for slotless structures is pedantically
       correct.
    ** PPRINT-INDENT accepts a request for an indentation of any REAL.
    ** PPRINT-TAB (and the FORMAT ~T directive) now indent by the
       correct amounts.
    ** The justification version of the FORMAT ~< directive treats
       non-zero minpad parameter correctly.

    3c5609fe · 0.8.15: · 
    changes in sbcl-0.8.15 relative to sbcl-0.8.14:
  * incompatible change: SB-INT:*BEFORE-SAVE-INITIALIZATIONS* and
    SB-INT:*AFTER-SAVE-INITIALIZATIONS* have been renamed
    SB-EXT:*SAVE-HOOKS* and SB-EXT:*INIT-HOOKS*, and are now part of
    the supported interface.
  * new feature: Single-stepping of code compiled with DEBUG 2 or
    higher and (> DEBUG (MAX SPACE SPEED)) is now possible.
  * new feature: saving cores with foreign code loaded is now
    supported on x86/FreeBSD, x86/Linux, and sparc/SunOS. (based on
    Timothy Moore's work for CMUCL)
  * bug fix: DEFTYPE lambda-list parsing now binds unsupplied keyword
    parameters to * instead of NIL if no initform is supplied.
    (reported by Johan Bockgaard)
  * bug fix: DEFINE-COMPILER-MACRO lambda-list parsing now binds
    correctly when FUNCALL appears as the car of the form. Note:
    despite this FUNCALL forms are not currently subject to
    compiler-macro expansion. (port of Raymond Toy's fix for the
    same from CMUCL, reported by Johan Bockgaard)
  * bug fix: FOR ... ON ... -clauses in LOOP now work on dotted lists
    (thanks for Teemu Kalvas)
  * bug fix: in FORMAT ~^ inside ~:{ now correctly steps to the next
    case instead of terminating the iteration (thanks for Julian
    Squires, Sean Champ and Raymond Toy)
  * bug fix: incorrect expansion of defgeneric that caused a style
    warning. (thanks for Zach Beane)
  * bug fix: slot accessor effective method computation works properly
    for classes with multiple non-standard applicable methods on
    SB-MOP:SLOT-VALUE-USING-CLASS.  (reported by Ralf Mattes)
  * on x86 compiler supports stack allocation of results of LIST and
    LIST*, bound to variables, declared DYNAMIC-EXTENT. (based on
    CMUCL implementation by Gerd Moellmann)
  * fixed some bugs revealed by Paul Dietz' test suite:
    ** FORMAT strings with both the ~<~:;~> form of the justification
       directive and pretty-printing directives cause an error.
