Log message:
Update to 2.1.10.

New in version 2.1.10

    * incompatible change: simd-pack without a specific element-type
      is no longer treated as containing integers. A type must be
      supplied for VOPs to work on such values.
    * minor incompatible change: the list form of the FUNCTION type
      specifier does not allow * as any argument type, but does allow
      * as a placeholder for wholly unspecified arguments when
      specifying the value(s) type.
    * minor incompatible change: the default (Lisp) toplevel option
      parser throws an error if it encounters an option which was
      intended to be used and removed by the C runtime. (#1945081,
      reported by Luke Gorrie)
    * new feature: there is now a defined interface for defining
      foreign callable functions, which can be used for passing
      callbacks to foreign functions or for calling Lisp code from the
      foreign world as a shared library (preliminary support). See the
      revised manual section "Calling into Lisp From C" for more
    * enhancement: arg-count mismatches in self-calls in defmethod are
      reported. (#1912436, reported by 3b)
    * enhancement: the SB-CLTL2 contrib now returns type information
      for generated structure accessors. (#1934859, reported by SATO
    * optimization: code generation is improved for modular arithmetic
      involving signed operations.
    * platform support:
        * x86-64 machine code emitter crash when attempting to
          assemble some vector instructions. (#1945975, thanks to
          Marco Heisig)
        * conditional move instructions are now supported on arm64.
        * a number of new peephole optimizations have been implemented
          on arm64.
        * arm64 on Darwin now uses gcc-compatible thread-local storage.
    * bug fix: compiler notes are no longer emitted when compiling
      FORMATTER forms, including when implicitly triggered on a
      constant string argument to FORMAT. (#1946246, reported by SATO
    * bug fix: a compiler error when attempting to compile a call to
      AREF with too many dimensions. (#1902985)
    * bug fix: harmonize the behaviour of SLOT-BOUNDP on
      non-standard-objects between the various ways in which it can be
      called. (#732229, reported by Zach Beane)
    * bug fix: FTRUNCATE and similar functions are now more careful
      about deriving facts about the sign of zero they might
      return. (#1732009, reported by Paul Dietz)

New in version 2.1.9

    * minor incompatible change: the experimental DEFCAS macro has
      been removed.
    * minor incompatible change: finalizing classes with slots with
      duplicate symbol-names will only emit a warning if either slot
      name is an exported symbol. (#1943559)
    * platform support:
        * the debugger is better able to display SIMD packs. (thanks
           to Marco Heisig)
        * fix a bug in zeroing YMM registers. (thanks to Marco Heisig)
        * fix instruction definitions for SSE blend and shuffle vector
          instructions. (thanks to Marco Heisig)
        * handle heap corruption exceptions in our exception handler
          on win64.
        * improve WAIT-UNTIL-FD-USABLE on Windows, reducing
          busy-looping. (thanks to Fabio Almeida)
    * bug fix: EQUALP hash tables whose keys contain arrays containing
      floats should behave correctly. (#1942424, reported by Nicolas

New in version 2.1.8

    * minor incompatible change: the experimental DEFINE-CAS-EXPANDER
      macro has been removed.
    * minor incompatible change: the hooks in *INIT-HOOKS* are called
      before starting the finalizer or other non-user threads. (thanks
      to Sean Whitton)
    * platform support:
        * many improvements to code generation on arm64.
        * avoid slow forms of the bit test instructions BT, BTS, BTR on x86-64.
        * fix a bug in loading large core files on the Apple
          M1/arm64. (thanks to Mayank Manjrekar)
        * fix a bug in loading core loading on the Apple
          M1/arm64. (reported by Eric Timmons)
    * enhancement: the block-compiler is more robust to files with
      intermingled compile-time and load-time effects. The semantics
      of the block-compiler remain not-entirely ANSI
      compatible. (thanks to Sean Maher)
    * enhancement: (CAS SAP-REF-<x>) and CAS on alien integers is
      implemented on ppc64 and x86-64, working towards fixing #1894057
    * bug fix: fix OPEN-STREAM-P on streams closed by saving a
      core. (#1938433, reported by Guillaume LE VAILLANT)
    * bug fix: remove a spurious warning from COERCE. (#1920931,
      reported by Andrew Berkley)
    * bug fix: remove a warning from inlining
      SET-EXCLUSIVE-OR. (#1936470, reported by Jerome Abela)

Log message:
Update to 2.1.7.

New in version 2.1.7

    * incompatible change: on certain platforms (currently just
      x86-64), dynamic-extent arrays specialized on character and
      numeric types and created without either :INITIAL-ELEMENT or
      :INITIAL-CONTENTS will reflect previous contents of the stack
      instead of #\null (or 0) in all elements.
    * minor incompatible change: SB-SPROF:START-PROFILING no longer
      silently does nothing if the clock is already running. It
      instead stop and restarts with the newly provided options, and
    * minor incompatible change: the system attempts to refer to the
      supplied pathname in compiler diagnostics, if relevant, rather
      than the truename.
    * enhancement: new contrib module sb-graph producing graphical
      visualizations of Intermediate Representations of SBCL
      compilation data structures.
    * platform support:
        * improved code generation for unary minus in modular contexts
          on arm64.
        * make the disassembler annotations slightly more robust on arm64.
        * release space back to the Operating System on Windows.
        * improve the test for whether pages need to be committed on Windows.
        * fix a bug in the use of the VPCMPEQD opcode on
          x86-64. (#1928516, thanks to Marco Heisig)
    * optimization: the type of (LOOP ... COLLECT ...), and the type
      of COLLECT INTO variables, is derived as LIST. (#1934577,
      reported by SATO shinichi)

New in version 2.1.6

    * minor incompatible change: COMPILE-FILE does not merge the input
      file's pathname-directory into the output path if :OUTPUT-FILE
      was specified and has a directory that is not :UNSPECIFIC.
    * platform support:
        * improvements to unwind code generation on arm64.
        * on x86-64, accept three operands for vshufpd. (reported by
          Bela Pecsek)
        * on x86-64, improvements to use of popcount
        * improve exception handling on 64-bit Windows. (thanks to
          Luis Borges de Oliveira)
    * bug fix: allow use of macros with improper argument
      list. (#1929623, thanks to Sean Maher)
    * bug fix: COERCE no longer attempts to guess what the user meant
      if they provide a type specifier of a union of types other than
      STRING. (#1929614)
    * bug fix: print a single trailing zero after the decimal point
      for FORMAT ~E if there are no digits remaining to be printed and
      the width allows it. (#883520)

        * bug fix: on x86-64, loading all-1s into an AVX2 register no
          longer causes an error. (thanks to Marco Heisig)
        * bug fix: on arm64, improve disassembly of ADD with constant
          0 as MOV
        * enhancement: on arm64, support debugger commands
          RETURN-FROM-FRAME and RESTART-FRAME more efficiently.
        * enhancement: on x86-64, add support for vshuf* AVX2
          instructions. (reported by Bela Pecsek)
        * optimization: faster function calls on arm64.
        * optimization: (SETF SBIT) is faster on x86-64.
    * bug fix: INTEGER-DECODE-FLOAT was computing the wrong answer for
      denormal double floats. (#1926383, reported by Stavros Macrakis)
    * bug fix: RANDOM on a floating point argument now does not
      cons. (reported by Tito Latini)
    * bug fix: fix a compiler crash in type derivation of
      LOGTEST. (#1928243)
    * bug fix: fix a compiler failure when a declared function type
      contains a literal structure with a valid MAKE-LOAD-FORM
      method. (#1929160, thanks to Yurii Hryhorenko)
    * optimization: FBOUNDP on a constant symbol is now faster.
    * optimization: file compilation now produces smaller fasls for
      files which reference package literals.
    * optimization: derive the type of calls to FLOAT-SIGN.

Update to version 2.1.4.

New in version 2.1.4

    * platform support:
        * work around address-space randomization causing instability
          on new versions of MinGW. (#1921141)
    * bug fix: RANDOM on floats returns values strictly less than the
      float argument.
    * bug fix: compiler error on x86-64 resulting from attempting to
      zero a memory location with xor. (reported by Eric Marsden)
    * optimization: extended loops updating iteration variables with
      THEN can perform specialized arithmetic for those updates.
    * optimization: in some cases, the jump table resulting from a
      compilation of TYPECASE is simpler.
    * optimization: on x86-64, IF BOUNDP followed by SYMBOL-VALUE can
      elide some memory loads and tests.

New in version 2.1.3

    * bug fix: structures and conditions are now TYPEP all
      classes in the class precedence list of their
      class. (reported by Luis Oliveira)
    * bug fix: derivation of the result type from subtraction
      sometimes erroneously excluded zero. (#1916895)
    * bug fix: reduce the number of places where the system
      permissively accepts the symbol * as a type specifier where
      it should not be accepted. (#1860919)
    * bug fix: the code-walker used by the system's
      implementation of CLOS can handle defuns declared
      inline. (reported by Don Cohen)
    * optimization: EQUALP on specialized vectors and arrays is faster.
    * optimization: support routines for EQUALP hash tables
      generate less garbage.

New in version 2.1.2

    * platform support:
        * support for ARM64 macOS;
        * improvement in coverage mark implementation on non-x86oid backends,
          approaching the existing x86oid support;
        * more empirically-robust retrieval of the program counter from

      incorrectly computed. (#1912863, reported by James
    * bug fix: better understanding of array simplicity (or
      otherwise) in the type system. (#1903241)
    * bug fix: unions of rational and integer types now have a
      single canonical form, allowing more correct reasoning
      about them in the type system.
    * bug fix: less likely to overclaim certainty about type
      equality of union types. (#1916040)
    * bug fix: HANDLER-BIND evaluates the forms producing handler
      functions only once. (#1916302, reported by Christophe
    * optimization: FIND on constant sequences can be compiled
      into a jump table, in a similar manner to POSITION
    * optimization: the compiler's awareness of numeric contagion
      rules for operations on pairs of floating point numbers is
      improved. (#1914094, thanks to Andrew Berkley)

New in version 2.1.1

    * platform support:
        * restore non-threaded NetBSD builds;
        * adjust how the finalizer thread is started; (#1906571, #1907872)
        * fix the encoding of PEXTR on x86-64;
    * minor incompatible change: emit warnings for list iteration
      forms when the object being iterated over is known not to be a
      list. (#1908819, reported by Michael Fiano)
    * bug fix: detect 2 or 1 as an invalid number of arguments passed
      to optimized slot reading or writing effective method
      respectively. (#1909659, reported by Michal Herda)

    * bug fix: literal (read-time evaluated) NaNs in source code no
      longer cause compiler crashes. (#1909881, reported by Michal
    * bug fix: detect more erroneous syntax in method
      bodies. (#1912362, reported by Paul M. Rodriguez)
    * optimization: the compiler's understanding of EXPT is improved,
      reducing the introduction of COMPLEX types. (#1908830, reported
      by Michael Fiano)
    * optimization: the compiler is better at computing numeric
      contagion when (COMPLEX FLOAT) types are involved.
    * micro-optimizations:
        * moving from slightly-bigger-than-fixnum ranges is more
          efficient on x86-64;
        * encode character comparisons with smaller operands on x86-64;
        * truncating (and related operations) on floats can be inlined
          in more cases on 64-bit platforms;
        * rounding can use specialized instructions on ARM64 and on
          x86-64 when SSE4 is available;

        * floating point error reporting on OS X (#309454)
        * load-shared-library not working from non-main threads on OS

    * minor incompatible change: (ARRAY NIL (*)) is not a subtype of
      STRING, as is consistent with a majority of maintained CL
    * minor incompatible change: ARRAY-RANK-LIMIT is decreased from

    * optimization: TYPEP on structure types is faster and more
      compact on x86[-64] and ppc64.
    * optimization: LOGCOUNT is faster on arm64.
    * optimization: SIGNUM can be inlined if its argument type is
      known. (#1903533)

      x86-64. (#1901685, reported by Marco Heisig)

New in version 2.0.10

    * minor incompatible change: the funarg given to
      SB-SPROF:MAP-TRACES does not receive a wallclock time with each
    * minor incompatible change: INTERNAL-TIME-UNITS-PER-SECOND has
      been increased to 10^6 on 64-bit architectures.
    * minor incompatible change: SIGPIPE is ignored by default again. (#1897624)

      :LINKAGE-TABLE feature is now unconditionally compiled in, and
      the corresponding entry in *FEATURES* has been removed.
    * enhancement: style-warnings are issued for variables which have
      an assignment but no "for-value reference" (per CLHS glossary
    * bug fix: SB-CLTL2:MACROEXPAND-ALL did not expand
    * bug fix: CPUID-based feature detection had an index/mask
      confusion (#1899239)
    * bug fix: fix a deadlock on Windows (#1896802)
    * bug fix: eliminate type errors when wall clocks go back
      (#1028026, #1032111)

        * parse vmmap output more liberally (#1897722, reported by Bob Felts)

New in version 2.0.9

    * 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
    * platform support:
        * a number of obsolete portability layers (particularly on the
          Windows platform) have been removed in favour of direct
          calling of the native interfaces.
        * RUN-PROGRAM now accepts a :WINDOW argument to control
          whether a subprocess window should be displayed. (Thanks to
          Luis Borges de Oliveira)
        * the use of futexes implied by :SB-FUTEX is now implemented on FreeBSD.
    * bug fix: SB-SPROF can distinguish between SBCL-internal assembly routines.
    * bug fix: SB-SPROF has better output in its reports for anonymous
    * optimization: CALL-NEXT-METHOD with supplied arguments in
      required positions is now faster if the supplied arguments are
      EQL to the original arguments.

New in version 2.0.8

    * platform support:
        * added support for NetBSD/aarch64;
        * threads on Linux now have OS-visible names;
        * removed unnecessary emulation of pthread functions on Windows;
        * work around a sigwait() bug on Mac OS X;
        * allow safepoint build on Mac OS X, though it probably
          doesn't work very well (reported by Chris Wagner, #1382811)
        * removed stub support for HPUX.
    * optimization: SB-THREAD:MAKE-THREAD is faster on most platforms.
    * optimization: faster RATIONAL when the result is a RATIO.

    * bug fix: EQUALP on pathnames was wrong
    * bug fixes: fix compiler issues in:
        * COUNT (#1889391)
