sbcl Debian release 2:1.2.2-1

changes in sbcl-1.2.2 relative to sbcl-1.2.1:
  * incompatible change: the #\` ("backquote") reader macro was reimplemented
    to support robust pretty-printing. Reading a form involving #\` produces
    an invocation of the QUASIQUOTE ordinary macro which may contain subforms
    that are not lists. Code that unportably attempts operations on
    un-evaluated forms resulting therefrom, e.g.
      (SUBST a b (read-from-string "`(x (,y))"))
    might generate incorrect results and/or errors.
  * enhancement: support for GNU/kFreeBSD x86.
  * enhancement: ATOMIC-INCF and ATOMIC-DECF can operate on (CAR x), (CDR x)
    and DEFGLOBAL variables of type fixnum.
  * enhancement: arithmetic constant reduction is now performed on defconstant
    constants too. (lp#1337069).
  * bug fix: certain ftype proclamations containing &optional t &rest t no
    longer cause subsequent definitions to signal bogus style-warnings.
  * bug fix: #\Bell and #\Bel now read to different characters. (lp#1319452).
  * bug fix: CAS SYMBOL-VALUE on locally special variables didn't work.
    (lp#1098355)

changes in sbcl-1.2.1 relative to sbcl-1.2.0:
  * enhancement: GENCGC is enabled on ARM.
  * enhancement: better error reporting for invalid calls to local functions.
  * enhancement: support for GNU/kFreeBSD distributions.  (lp#1079954, thanks
    to Christoph Egger)
  * enhancement: experimental support for threads on NetBSD/x86-64.  (thanks
    to Robert Swindells)
  * enhancement: support for DragonFly BSD.  (lp#1292845, thanks to Vasily
    Postnicov)

    (lp#1317308)
  * bug fix: accessing NIL arrays stopped producing errors. (lp#1311421)
  * bug fix: DISASSEMBLE no longer prints unwanted stuff. (lp#1251861)
  * bug fix: compiling SVREF on unknown types no longer produces scary errors.
    (lp#1258716)
  * bug fix: assorted LOOP fixes and enhancements. (lp#645534, lp#1322923,
    lp#700538, lp#613876, lp#695286, lp#798388)
  * bug fix: silence compiler notes from the SEARCH transform. (lp#1071310)
  * bug fix: array type intersection handles T and unknown element types
    correctly. (lp#1258716)
  * bug fix: fix a corner case in array type unparsing that would result in
    misleading translations from our internal type representation.
  * bug fix: array-rank now sees through union and intersection types.
    (lp#1310574)
  * bug fix: when DECLARE expressions are in the wrong place, be careful not
    to attempt to evaluate the subforms.  (lp#573747; thanks to Roman
    Marynchak)
  * bug fix: misplaced and missing declarations in DEFTRANSFORM. (lp#1066451)
  * bug fix: FBOUNDP returned NIL for a class of incorrect function names
    instead of signaling an error. (lp#1095483)
  * bug fix: fix a compile-time AVER in regalloc: lifetime analysis
    used to (rarely) introduce duplicate conflict markers in a single
    TN/block pair. (lp#1327008)

sbcl Debian release 2:1.2.0-1

  * optimization: COERCE is now more effecient for more cases when the type is
    known at compile-time.
    (lp#1309815)
  * bug fix: correctly inherit condition initforms. (lp#1300904)
  * bug fix: properly pprint literal functions inside nested lists.

changes in sbcl-1.1.16 relative to sbcl-1.1.15:
  * minor incompatible change: improve read/print consistency for pathnames on
    Win32, by using the circumflex character #\^ as the escape character.
    (lp#673625)
  * enhancement: SB-EXT:DEFINE-LOAD-TIME-GLOBAL. (lp#1253688)
  * enhancement: Loading fasls with symbols from an undefined package includes
    the name of the symbol in the error message.
  * bug fix: problems when redefining classes and doing TYPEP on classes
    concurrently. (lp#1272742)
  * bug fixes to the x86-64 XCHG instruction:
    ** it was misencoded when used with RAX, R8-R15 registers. (reported by
       Eric Marsden)
    ** it was misencoded when used to exchange EAX with itself.
    ** the disassembler wrongly printed XCHG RAX, R8 and the corresponding
       32- and 16-bit variations as NOP.
  * bug fix: the disassembler outputs source annotations in the right place
    and no longer randomly drops some of them. (lp#1249205)
  * bug fix: fix commutative-arg-swap from introducing undumpable structures
    into code, prevent code with errors from being compiled. (lp#1276282)
  * bug fix: pathnames with :back in their directory component are succeffully

  * bug fix: the deterministic profiler now uses ENCAPSULATE functionality to
    wrap functions around. (lp#309086)

changes in sbcl-1.1.15 relative to sbcl-1.1.14:
  * new feature: the iterative spilling/coloring register allocator developed
    by Alexandra Barchunova during Google Summer of Code 2013 is now merged
    in.  By default, it only activates for functions that optimize with
    (speed 3) and (> speed compilation-speed), but setting
    sb-regalloc:*register-allocation-method* to :iterative forces its
    execution.  The previous behaviour can be obtained by instead setting that
    variable to :greedy.  Thanks again to Google for their support, and, more
    crucially, to Alexandra Barchunova for her hard work.
  * optimization: make-array with known element-type and unknown dimensions is
    much faster.
  * optimization: make-array with unknown element-type is faster as well.
    (lp#1004501)
  * enhancement: sb-ext:save-lisp-and-die on Windows now accepts
    :application-type argument, which can be :console or :gui. :gui allows
    having GUI applications without an automatically appearing console window.
  * enhancement: reduced conservativism on GENCGC platforms:
    conservative roots must be valid-looking tagged pointers or point
    within a code object, not merely point to within the allocated part
    of a page, in order to pin a page.
  * enhancement: support for "Mac Roman" external format.
  * enhancement: encapsulation of named generic functions now happens without
    altering the identity of the function bound to the name.
  * bug fix: Windows applications without the console window no longer misbehave.
    (patch by Wilfredo Velazquez, lp#1256034).
  * bug fix: modular arithmetic optimizations do not stumble on dead branches
    with bad constants. (reported by Douglas Katzman)
  * bug fix: CLISP can be used again as a cross-compilation host.
    (Thanks to Vasily Postnicov, lp#1261451)
  * bug fix: run-program crashed with :directory nil. (lp#1265077)

sbcl Debian release 2:1.1.14-1

    propagation pass. (lp#1229340)
  * optimization: [N]BUTLAST perform a single pass over the list. (lp#1245697)
  * optimization: EQUALP on structures with raw slots (double-float/complex)
    no longer conses and is faster.
  * optimization: RESTART-CASE expands to more compact code.
    Thanks to Jan Moringen. (lp#1249055)

  * enhancement: better ARRAY-RANK result derivation. (lp#1252108)
  * bug fix: EQUALP now compares correctly structures with raw slots larger
    than a single word.
  * bug fix: contribs couldn't be built on Windows with MinGW.
  * bug fix: Better pathname handling on Windows. (lp#922117)
  * bug fix: OPEN reports a more meaningful error when an existing file is
    opened for output with :if-exists :new-version.  Thanks to Philip
    Munksgaard. (lp#455381)

  * optimization: better distribution of SXHASH over small conses of related
    values.  (lp#309443)
  * other improvements to SXHASH:
    ** use the whole of the positive-fixnum range for SXHASH of fixnums
  * enhancement: The error message when calling an undefined alien function
    includes the name of the function on x86-64.
  * enhancement: sb-ext:run-program now supports :environment on Windows.
  * enhancement: ASDF is no longer required to load contribs at runtime.

    clusters better in some cases
  * enhancement: SOME/ANY/other quantification higher-order functions no
    longer cons. (lp#1070635)

  * bug fix: (the [type] [constant]) now warns when [constant] matches
    [type] except for the number of values.  (Reported by Nathan Trapuzzano
    on sbcl-help)
  * bug fix: signal errors in required cases of slot-definition initialization
    protocol.  (lp#309072)
  * bug fix: run-sbcl.sh works better in the presence of symlinks on OS X.
    (thanks to Stelian Ionescu, lp#1242643)
  * bug fix: when given a restart object, FIND-RESTART checks whether the
    restart is active and, when a condition is supplied, whether the restart
    is associated to a different condition (lp#774410)

    constructors no longer fails to merge actual and default initargs
    (thanks to Jan Moringen, lp#1179858)
  * bug fix: the compiler-macro for MAKE-INSTANCE when emitting "fallback"
    constructors handles non-KEYWORD initialization arguments more correctly.

    arguments during copying on x86 and x86-64; it may still happen on other
    platforms when there are more fixed arguments than stack slots.
    (reported by Jan Moringen)

sbcl Debian release 2:1.1.11-1

changes in sbcl-1.1.11 relative to sbcl-1.1.10:
  * enhancement: support building the manual under texinfo version 5.
    (lp#1189146)

    A warning is instead appended to the regular banner, and may be muted with
    --noinform.  (lp#728247)

  * bug fix: improved threading on PPC.
  * bug fix: ROOM works again on Windows.  (lp#1206456)
  * bug fix: Streams were flushed even when there was one byte still left in
    the buffer. (lp#910213)
  * bug fix: OPEN handles correctly when :if-exists and :if-does-not-exist are
    either NIL or :ERROR.  (reported by Jan Moringen)

changes in sbcl-1.1.10 relative to sbcl-1.1.9:
  * enhancement: ASDF has been updated to 3.0.2.
  * optimization: stack frames are packed more efficiently on x86oids, which
    ought to reduce the frequency of Methuselahn conservative references (it
    certainly helps with gc.impure.lisp / BUG-936304 on x86).
  * optimization: on x86 and x86-64, integer negation forms like (- x) are now
    recognized in modular arithmetic contexts, and compile to native negate,
    rather than going through bignums only to keep the low bits.
  * bug fix: Compiling potential modularic arithmetic forms does not cause type
    errors when some integer types lack lower or upper bounds. (lp#1199127)

  * optimization: (mod fixnum) type-checks are performed using one unsigned
    comparison, instead of two.

  * bug fix: uninitialized type-error conditions can now be printed.
    (lp#1184586)
  * bug fix: tests for sb-bsd-sockets no longer use a predefined port for
    listening, allowing several tests to run in parallel.
  * bug fix: during disassembly to *COMPILER-TRACE-OUTPUT* instruction
    prefixes as used on x86 and x86-64 no longer sometimes print incorrectly.
    (lp#1085729)
  * bug fix: Specialised SIMD-PACK types can be negated.
  * bug fix: Modular arithmetic is more robust. (incidentally fixes another bug
    reported by Eric Marsden)
  * bug fix: FP return values from foreign calls are always rounded to single
    or double float precision on x87.
  * bug fix: Known-safe vector access on x86oids should not fail spuriously
    when the index is of the form (+ x constant-positive-integer).
  * bug fix: Remove GPL-licensed files from source distribution. (lp#1185668)
  * bug fix: backtrace printer no longer tries to create very large lists when
    the arg-count register is clobberred by other code. (lp#1192929)
