    sbcl release 2:2.6.0-1 for unstable
    
    [dgit distro=debian split --quilt=linear]
    [dgit please-upload source=sbcl version=2:2.6.0-1 upstream-tag=sbcl-2.6.0 upstream=fc9f5a9d14cb923eb31dbe7ef443b134137819d2]
    
  • sbcl-2.6.0

    changes in sbcl-2.6.0 relative to sbcl-2.5.11:
      * enhancement: the compiler will recognize certain combinations of
        high-level optimizations as expressible by shorter machine instruction
        sequences, documented in the manual under "Recognized idioms" in the
        "Efficiency" section.
      * enhancement: the SB-COVER code coverage tool can emit a report in a format
        compatible with the LCOV open-source tool.
      * bug fix: compiled code calling EXPT with constant integer exponent (or
        1/2) and floating point base is more consistent with out-of-line EXPT.
        (lp#1899969, lp#2136082)
      * bug fix: fix SCALE-FLOAT on denormal floats.  (lp#2000178, re-reported by
        Barton Willis)
      * bug fix: the system's test of constructing an ELF core is compatible with
        storing code coverage information.  (lp#2131956)
      * bug fix: inconsistent result from SUBTYPEP on array types.  (lp#2132250)
      * bug fix: the SB-COVER reporting utilities can now annotate source files
        containing array literals using #A(<dims> <eltype> . <contents>) syntax.
        (lp#2134290)
      * bug fix: compiler error resulting from losing some already-computed
        derived type information.  (lp#2136852)
      * bug fix: miscompilation of DPB involving non-word-sized intermediate
        results but a word-sized final result.  (lp#2137028)
      * bug fix: compiler error when asserting the result of a known non-list to
        be of a type union involving a CONS with a given CAR.  (lp#2137030)
      * bug fix: miscompilation of DPB with constant byte positions above the
        number of bits in a word.  (lp#2137046)
      * bug fix: miscompilation of PHASE with a negative zero argument.
        (lp#2137068, lp#2137119)
      * bug fix: failure to round-trip types involving positive and negative zeros
        of different floating point representations.  (lp#2137140)
      * optimization: machine arithmetic can be used when bit-shifting bignum
        inputs in a modular arithmetic context.
      * optimization: extending an association list, including using backquote
        notation, is recognized as ACONS and is potentially stack-allocatable.
      * optimization: some intermediate copies of lists are elided for calls to
        maybe-copying operations surrounded by a call to COPY-LIST.
      * optimization: a number of comparison operations on rationals are
        simplified where possible.
      * optimization: a number of arithmetic operations recognize and elide double
        negations or calls to ABS.
      * optimization: tracking code with coverage information uses a weak vector
        per fasl file, rather than a list of per-function weak pointers.
      * optimization: REDUCE has been tweaked for better performance both on lists
        and vectors.
      * optimization: for simple-bit-vectors of the right alignment and length,
        REVERSE will operate a word-at-a-time.

  • sbcl-2.5.11

    changes in sbcl-2.5.11 relative to sbcl-2.5.10:
      * incompatible change: the compiler's internal representation of "source
        paths" for unquoted forms within backquotes has changed.  Other developer
        tools using this representation, including callers of some exported
        SB-INTROSPECT functions, will misreport the location of signalled
        conditions and/or definitions in top-level forms including backquotes and
        commas.
      * minor incompatible change: undefined syntaxes following
        *READ-BASE*-related reader macros (such as #B, #O, #X, #R) now signal
        reader errors.
      * minor incompatible change: the convenience reader syntax pkg::(...) no
        longer triggers package locks for the PKG package.
      * minor incompatible change: building with the SB-DEVEL feature inhibits
        identical code folding at the end of the build of the SBCL system itself.
      * enhancement: improve the compiler's knowledge of the dimensions of the
        result of MAKE-ARRAY.  (lp#2130477, thanks to Vasily Postnicov)
      * enhancement: the SB-COVER contributed module has been made substantially
        more robust; collecting coverage no longer inhibits various CLOS
        optimizations.  (For SBCL developers, it is now capable of reporting on
        the coverage of the SBCL system itself, provided it is built with the new
        :SB-COVER-FOR-INTERNALS build-time feature.)
      * bug fix: REQUIREing the SB-MD5 contributed module no longer installs a
        compiler optimization policy restriction of SPACE being at least 1.
      * bug fix: don't miscompute the sizes of garbage collector data structures
        for running with dynamic space heap sizes above 128GiB.
      * bug fix: ENOUGH-NAMESTRING when the pathname and defaults arguments are
        both logical pathnames with the same host returns a shorter string than
        previously.
      * bug fix: the compiler retains fewer temporary data structures when
        compiling code with coverage data.
      * bug fix: requiring the SB-MD5 contrib module no longer installs a
        restriction on the SPACE optimization quality.
      * bug fix: internal compiler floating point error while compiling certain calls
        to CEILING.  (lp#2132231)
      * bug fix: miscompilation of TYPEP on intersections of types including
        rational ranges.  (lp#2132207)
      * bug fix: miscompilation of MISMATCH from insufficiently cautious type
        derivation.  (lp#2132187)
      * bug fix: internal compiler error while compiling ASH from an incorrect
        consistency check.  (lp#2132156)
      * bug fix: internal compiler error from missing constant-folding stub for
        internal function.  (lp#2132126)
      * bug fix: miscompilation of GET-PROPERTIES at low SAFETY optimization
        qualities.  (lp#2131985)
      * bug fix: internal compiler error while generating code for multiplications
        of fixnums where the result is also asserted to be a fixnum. (lp#2131894)
      * bug fix: the asserted real range of ATANH was incorrectly stated as
        [-1,1].  (lp#2131711)
      * bug fix: incorrect type error resulting from wrong type derivation of
        REDUCE #'LOGIOR.  (lp#2131699)
      * bug fix: specialized XEPs should not be generated during
        block-compilation or interpretation.  (lp#2131118)
      * bug fix: fix a wrong compiler transform for MAKE-ARRAY leading to
        miscompilation.  (lp#2131048)
      * bug fix: miscompilation of type checks of (UNSIGNED-BYTE <X>) for large
        <X>.  (lp#2130028)
      * bug fix: it is now possible to inline functions containing SPECIAL
        declarations on symbols in locked packages.  (lp#2129827, reported by
        Scott L. Burson)
      * bug fix: various internal compiler errors.  (lp#2132022, lp#2129649)
      * bug fix: various wrong results and inconsistencies from SUBTYPEP on ARRAY
        types.  (lp#2130374, lp#2130424, lp#2130441, lp#2130457, lp#2130508,
        lp#2130518, lp#2130526, lp#2130542, lp#2130588, lp#2130950, lp#2131079,

      * optimization: LOGTEST participates in compiler transforms related to
        modular (machine-sized) arithmetic.
      * optimization: more arithmetic combinations simplifications.
      * optimization: (car (list a)) doesn't allocate a list.

           tooling.
        ** provide a plugin to lldb to display backtraces (contrib/lldb_bt.py).
        ** an experimental option for performing GC without interrupting and

           (for arm64, x86-64 (outside of Windows, where that's already the case.))
      * bug fix: some interactions between TWO-WAY-STREAM (and ECHO-STREAM) and
        user-defined streams have been cleaned up.
      * bug fix: the SB-COVER contributed module can now annotate source files
        containing COMPLEX literals.  (A number of other more minor cosmetic
        issues have also been fixed).
      * bug fix: compiler crash from reoptimizing with some stale type information.
        (lp#2125944)
      * optimization: SLOT-VALUE calls with known slot-name on values which are of
        type (OR NULL <STRUCT>) are transformed to a null check and a structure
        access.
      * optimization: the compiler will apply constraints to the result of calling
        RANDOM.  (lp#2126978, thanks to Vasily Postnicov)
      * optimization: the compiler will perform type derivation on CL:APPLY called
        with a known function.
      * optimization: fusion of type checking and move of 64-bit integers is
        enabled on arm64 and x86-64.

        (if v constant1 constant2)
    
  • sbcl-2.5.9

    changes in sbcl-2.5.9 relative to sbcl-2.5.8:
      * minor incompatible change: remove (SETF SB-EXT:POSIX-GETENV), which only
        ever existed as an operator in SBCL on Windows.
      * minor incompatible change: (LOG -0.0) now returns
        SINGLE-FLOAT-NEGATIVE-INFINITY, more consistently with IEEE 754.
      * minor incompatible change: (EXPT 0.0 0.0) now returns 1.0, rather than
        signalling an error.
      * platform support
        ** restore functionality on NetBSD.  (thanks to Masatoshi SANO)
        ** fix building SBCL as a shared library on ARM64.  (lp#2122059, reported
           by Guillaume LE VAILLANT)
      * optimization: TYPEP with array types does less work in many cases.
      * optimization: COMPLEMENT on a known function can be transformed away in
        more cases.
      * optimization: calls to local functions with &REST arguments can be
        optimized in more cases.
      * optimization: bound checks can be eliminated in ROW-MAJOR-AREF based on
        constraints relating the index to the available array elements.
        (lp#2121253, thanks to Vasily Postnicov)
      * optimization: function type declarations no longer inhibit inlining local
        functions.  (lp#2121351, reported by kbhit)
      * optimization: bulk movement of memory in the system is implemented with
        less overhead around memmove().
      * optimization: MAKE-ARRAY with dimensions coming from ARRAY-DIMENSIONS on
        an array with known dimensions avoids consing an intermediate dimensions
        list.
      * optimization: a number of arithmetic operators and relations in
        combination with some constant arguments do partial expression

  • sbcl-2.5.8

    changes in sbcl-2.5.8 relative to sbcl-2.5.7:
      * minor incompatible change: SB-THREAD:MAIN-THREAD-P can only be applied to
        threads, not arbitrary lisp objects.
      * minor incompatible change: the instruction-combining (peephole)
        optimization pass does not run if COMPILATION-SPEED has a higher value
        than SPEED.
      * platform support:
        ** on arm64, provide better backtraces in the statistical profiler's
           reporting, along with better detection of assembly routines, local
           functions and callers of foreign code.
        ** on ppc64le, make --dynamic-space-size behave as documented.
           (lp#2121255)
        ** on x86-64, handle more cases in the ALU+TEST peephole optimization.
      * bug fix: for file-streams with :DIRECTION :IO, input and output file
        positions should no longer get out of sync.  (lp#1600610, reported by
        Guillaume le Vaillant, test cases by Brent Benson)
      * bug fix: an infinite loop in SUBTYPEP for types involving negations of
        CONS of specialized ARRAY types.  (lp#2114755)
      * bug fix: miscompilation of a CASE form with small numeric keys.
        (lp#2119035)

        Brooke Tilley)
      * bug fix: allow ALU+TEST peephole optimizations to fire on x86-64.
        (lp#2120547, reported by Christoph Breitkopf)

  • sbcl-2.5.7

    changes in sbcl-2.5.7 relative to sbcl-2.5.6:
      * enhancement: the encapsulate mechanism can be used to wrap functions that
        are currently not FBOUNDP.
      * bug fix: internal compiler error in a failure of stack analysis during
        propagation of dynamic-extent.  (lp#2113935)
      * bug fix: address regression in type inference for TRUNCATE and other
        division-related operators.  (lp#2115305, reported by Vasiliy Postnicov)
      * bug fix: cleanup of the main thread is performed more carefully when SBCL
        is used as a shared library.  (lp#2115669, reported by Fedorov Alexander)
      * bug fix: the compiler does not lose track of the types of specialized
        external entry points for user-defined functions.  (lp#2115955, reported
        by Matt Kaufmann)
      * bug fix: adjust compiler template argument acceptability for increased
        usage scope.  (lp#2116150)
      * bug fix: provide a stub for ROTATE-RIGHT-WORD for constant-folding during
        compilation.  (lp#2117080)
      * bug fix: provide a stub for %MAKE-DOUBLE-FLOAT for constant-folding during

        optimized similarly to calls to SLOT-VALUE in non-method code.
      * optimization: calls to REPLACE with VECTOR first argument and LIST second
        argument are improved.
      * optimization: TYPECASE over a set of structure types known not to be

  • sbcl-2.5.6

    changes in sbcl-2.5.6 relative to sbcl-2.5.5:
      * enhancement: the compiler now recognizes when local functions (both named
        and anonymous) are used only as downward funargs in many situations and
        can stack allocate such closures even without explicit dynamic extent
        declarations. See the updated manual entry on stack allocation for more
        information and how user-code can declare funargs as downward.
      * minor incompatible change: optimization notes for a variable declared to
        be of type LIST will not be emitted for various transforms which are
        defined to operate on (OR NULL VECTOR).
      * minor incompatible change: some forms, including a THE form with an
        invalid type specifier, or a CASE form with bad entries, no longer produce
        a runtime error.  (They continue to provide a full warning at
        compile-time).
      * platform support
        ** on arm64, breakpoint-based stepping is now thread-safe.
        ** on arm64, backtraces after interrupts should be more correct.
        ** on x86-64 with the immobile-space feature, calling from assembly
           routines to lisp routines is more efficient.
        ** if arenas are enabled, users can define a lisp function to act as a
           handler to customize behaviour on arena exhaustion.
      * bug fix: address several bugs related to dynamic-extent declarations,
        inference, and stack allocation.
      * bug fix: the stack return page protection is temporarily disabled during
        GC, so that GC can complete even if it needs to write in the return page.
      * bug fix: the compiler generates code to the right entry point for specialized
        functions.  (lp#2111876, reported by Matt Kaufmann)
      * bug fix: the compiler's constraint derivation would sometimes not terminate.
        (lp#2113747)
      * bug fix: when the runtime structure representing a thread is re-used, the
        stack guard pages are restored.
      * bug fix: type checks for &OPTIONAL arguments are done only once.
      * bug fix: CEILING's docstring was wrong.  (reported by Dave Tenny)
      * bug fix: APPLY could be called with too many arguments when parsing MEMBER
        type specifications.  (reported by Zach Beane)
      * bug fix: the compiler could allow constant values of bad types to trigger
        optimizations.  (lp#2113977)
      * bug fix: internal compiler error when attempting to write out a type check
        for a value already proved to never exist (i.e. be of type NIL).
        (lp#2112475)
      * optimization: better division for signed-word dividends and unsigned-word
        divisors on arm64 and x86-64.
      * optimization: improvements to subtraction involving bignums and words on
        x86-64.

        functions with keys including fixnums and characters as well as symbols.
    
  • sbcl-2.5.5

    changes in sbcl-2.5.5 relative to sbcl-2.5.4:
      * minor incompatible change: the output from TRACE is now prefixed by a
        FRESH-LINE on *TRACE-OUTPUT*.
      * platform support:
        ** On Linux, the system is better at negotiating with the kernel to find
           locations for Lisp memory spaces, succeeding more often than
           previously.
      * bug fix: resolve signed/unsigned char mismatch in RUN-PROGRAM on Windows.
        (lp#2110525, reported by awlygj)
      * bug fix: compiler confusion given sufficiently complex derived type
        constraints.  (lp#2109902)
      * bug fix: compiler inconsistency in low-level representation leading to
        inconsistent transformations.  (lp#2109837)
      * bug fix: return NIL from calls to DOCUMENTATION on illegal function names.
      * bug fix: calls to APPLY or VALUES-LIST on some combinations of constant
        arguments could lose the constant nature after transformation.  (thanks to
        Hayley Patton)
      * optimization: some micro-improvements to bignum operations, particularly
        on x86-64 and arm64
      * optimization: allow the result of MAKE-STRING to be allocated on the stack
        when :element-type is unknown.
      * optimization: the compiler will recognize the use of ZEROP on the results
        of LENGTH and REM (on suitable operands) to avoid full computation of the
        intermediate result.
    
  • sbcl-2.5.4

    changes in sbcl-2.5.4 relative to sbcl-2.5.3:
      * enhancement: :FUN-END breakpoints now support the known values return
        convention when DEBUG > 0. This means that tracing local functions works
        in more situations.
      * platform support:
        ** on x86-64, relocation of static space is always enabled.
        ** save-lisp-and-die with :callable-exports can be used for sbcl.dll on
           Windows.
        ** Building with UCRT64 on Windows is now fully supported.
      * bug fix: :FUN-END breakpoints work on PowerPC, SPARC, and MIPS again.
      * bug fix: incorrect rounding when converting some bignums to floats.
      * bug fix: the second value of the truncation functions is more consistently
        computed for bignum floats.
      * bug fix: fix code generation for constants being considered from
        conflicting type propagation information.  (lp#2107652)
      * bug fix: fix 32-bit range check code generation on x86-64.  (lp#2106432)
      * bug fix: types are correctly propagated from the keyword argument
        processor to their uses.  (lp#2106358, reported by Vasily Postnicov)
      * bug fix: fix compilation error from CHECK-TYPE when the value checked is a
        keyword argument and the type specifier argument is not a valid type
        specifier.  (lp#2104089)
      * bug fix: generate stack-manipulation code in the presence of non-local
        exits and dynamic-extent declarations even more carefully.  (lp#2043242)
      * optimization: (LOGIOR A (- (MASK-FIELD (BYTE 1 constantN) A))), or its
        equivalent (LOGIOR A (- (LOGAND (ASH 1 constantN) A))), is recognized as
        an idiom for sign-extending the N+1-bit field in A, and can be used for
        signed modular arithmetic.
      * optimization: ROUND is faster for floats.
      * optimization: TRUNCATE/FLOOR/etc. are faster on ratios.
      * optimization: MAKE-SEQUENCE does not invoke the full type algebra when the
        provided type specifier is simple.
      * optimization: don't attempt to align branch targets if the SPACE
        optimization quality is greater than 1.
      * optimization: circularity detection for printing now places its temporary
        data structures on the stack.
      * optimization: faster GCD on fixnums, especially when the difference in
        magnitude is large.
      * optimization: the implementation of ISQRT has been replaced with the
        (faster) algorithm currently implemented in CPython.
    
  • sbcl-2.5.3

    changes in sbcl-2.5.3 relative to sbcl-2.5.2:
      * enhancement: breakpoint debugger commands have been added.  Included is a
        stepper based on breakpoints requiring no extra instrumentation.  However,
        it still has less functionality than the existing single stepper.  See the
        new debugger manual section titled "Breakpoint Commands" for more
        information on the new commands.
      * minor incompatible change: the behaviour of :save-runtime-options has been
        restored to match the documentation.  (lp#2096995, reported by Zach Beane)
      * minor incompatible change: invoking CHANGE-CLASS from user code no longer
        grabs the CLOS world lock.  Callers must take responsibility for ordering
        execution of CHANGE-CLASS and any changes to the class hierarchy.
      * platform support:
        ** (CAS SAP) is implemented on ARM v8.1 directly with CAS instructions.
        ** on x86-64, list constructors emit more compact code sequences,
           particularly in the presence of multiple references to the same object.
        ** on x86 and x86-64, fix the stack overflow check to use signed
           comparisons.
        ** on Darwin/arm64 and Linux/x86-64, provide a restart to disable
           floating-point exceptions of the type signalled, and another to disable
           all floating-point exceptions.
      * bug fix: cycle detection in class precedence lists happens before adding
        classes to the direct subclasses of the parent.
      * bug fix: stack-allocated unaligned cons cells no longer cause errors in
        the debugger.
      * bug fix: local function type declarations no longer inhibit tail calls in
        (SAFETY 0) code.  (lp#2039301)
      * bug fix: bad or unknown type specifiers in CHECK-TYPE do not crash or slow
        down the compiler.  (lp#2102644, lp#2102653, lp#2102714, lp#2104048)
      * bug fix: numerous bug fixes relating to the type system's handling of
        arrays make SUBTYPEP more reliable and less likely to express a
        contradiction.  (lp#1996980, lp#2100563, lp#2100728, lp#2100779,
        lp#2100784, lp#2100812, lp#2100825, lp#2101192, lp#2101215, lp#2101803,
        lp#2102684)
      * bug fix: improve other aspects of the type system's self-consistency.
        (lp#2101073, lp#2101170, lp#2101183, lp#2101189, lp#2101399, lp#2101589)
      * bug fix: fix compiler type error when deriving the type of FTRUNCATE.
        (lp#2101073)
      * bug fix: fix compiler error when deriving constraints for single-floats.
        (lp#2102759)
      * bug fix: startup tuning for particular microarchitectures no longer
        accidentally disables one of the optimizations.
      * optimization: ROW-MAJOR-AREF is transformed to use the same array
        machinery as one-dimensional array references.  (Thanks to Scott Burson
        for the suggestion)
      * optimization: list constructors emit shorter code sequences on x86-64,
        particularly in the presence of multiple references to the same object.
      * optimization: FLOOR and CEILING on ratios do not unnecessarily cons.
      * optimization: provide specialized CALL-NEXT-METHOD functions for the
        no-argument and full-argument cases.

  • sbcl-2.5.2

    changes in sbcl-2.5.2 relative to sbcl-2.5.1:
      * minor incompatible change: in some instances when the compiler cannot
        prove that a NIL-valued branch is unreachable, where NIL is not compatible
        with the expected type, a type warning will no longer be issued.
      * minor incompatible change: the compiler will more strictly treat type
        declarations for &OPTIONAL and &KEY arguments in FTYPE declarations, no
        longer effectively adding an implicit (OR ... <default>) type when the
        function itself has a default value not matching the declared type for
        that argument.
      * enhancement: type errors in structure constructors are now restartable,
        with a USE-VALUE restart provided.
      * enhancement: CHECK-TYPE warns about type conflicts at compile-time.
      * enhancement: FTYPE declarations for functions which set their parameters
        are checked.
      * enhancement: new print control variable SB-EXT:*PRINT-CIRCLE-NOT-SHARED*,
        when used in conjunction with *PRINT-CIRCLE*, prints #1# only for
        circularities and not simple sharing.
      * platform support
        ** on Windows, make sure to commit memory after zeroing during
           save-lisp-and-die. (lp#2097197, reported by _3b)
        ** on Linux, add the TCP_USER_TIMEOUT constant to SB-BSD-SOCKETS.  (thanks
           to Mihai Bazon)
        ** on *BSD, make TCP_KEEPCNT, TCP_KEEPIDLE and TCP_KEEPINTVL available
           where the OS supports it.
        ** on x86-64, optimize BOUNDP for known-global symbols.
        ** on x86-64, optimize KEYWORDP for some arguments.
        ** on arm64, don't trigger an assertion when using FMOV on complex
           single-float registers.
        ** on arm64, improve type checking for (AND SYMBOL (NOT NULL)).
      * bug fix: using structure read macros with shared structure markers no
        longer signals type errors when the shared structure is in a slot with a
        type.  (lp#308936)
      * bug fix: non-conforming user macros which modify their source no longer
        trigger internal errors.  (lp#1371719, reported by _3b)
      * bug fix: the combination of CONSTANTLY and DYNAMIC-EXTENT declarations no
        longer causes an internal compiler error.  (lp#2059950, reported by
        bohonghuang)
      * bug fix: treat inlined functions analogously to constants in the compiler.
        (lp#2095560, reported by Vasiliy Postnicov)
      * bug fix: FTYPE declarations for &optional and &key arguments do not
        include default values when checking types.
      * bug fix: Storing coverage data no longer leads to miscompilations allowing
        reachability of unreachable code.  (lp#2092451, reported by mrkissinger)
      * optimization: elide bounds-checking for multidimensional arrays with known
        dimensions.  (reported by aeth)
      * optimization: alien callbacks are generally less heavyweight.
      * optimization: REMOVE shares the tail of the input list when there's
        nothing to remove.
