Update to SBCL 1.0.55

New in version 1.0.55

  * enhancements to building SBCL using
      + --fancy can be specified to enable all supported feature
      + --with-<feature> and --without-<feature> can be used to
        specify which features to build with.
      + --arch option can be used to specify the architecture to
        build for. (Mainly useful for building 32-bit SBCL's on
        x86-64 hosts, not full-blows cross-compilation.)
  * enhancement: extended package prefix syntax
    <pkgname>::<form-in-package> which allows specifying name
    of the default interning package for the whole form.
  * enhancement: when *READ-EVAL* is true, arrays with element
    type other than T can be printed readably using #.-based
    syntax. (Thanks to Robert Brown)
  * enhancement: MAKE-ALIEN signals a storage-condition instead
    of returning a null alien when malloc() fails. (#891268)
  * enhancement: SB-EXT:PRINT-UNREADABLY restart for
    PRINT-NOT-READABLE conditions can be conveniently accessed
    through function with the same name, analogously to CONTINUE.
  * enhancement: SB-EXT:*SUPPRESS-PRINT-ERRORS* can be used to
    suppress errors from the printer by type, causing an error
    marker to be printed instead. (Thanks to Attila Lendvai)
  * enhancement: BACKTRACE and DESCRIBE now bind *PRINT-CIRCLE*
    to T, and generally behave better when errors occur during
  * enhancement: the test runner now takes a --report-skipped-tests
    argument to report the individual tests skipped as well as the
    number of skipped tests.
  * enhancement: undefined functions now appear in backtraces as
    ("undefined function") instead of ("bogus stack frame") on
  * enhancement: detected deadlocks no longer cause stderr to be
    spammed, and deadlock errors are reported in an easier-to-decipher
  * enhancement: DESCRIBE on type designators reports the
    expansion in more cases.
  * enhancement: SBCL now provides either an explicit :BIG-ENDIAN
    or :LITTLE-ENDIAN in *FEATURES*, instead of :BIG-ENDIAN being
    implied by lack of the :LITTLE-ENDIAN feature. (Thanks to
    Luis Oliveira, #901661)
  * enhancement: better disassembly of segment-prefixes on x86
    and other instruction prefixes (e.g. LOCK) on x86 and x86-64.
  * optimization: FIND and POSITION on bit-vectors are orders of
    magnitude faster (assuming KEY and TEST are not used, or are
    sufficiently trivial.)
  * optimization: SUBSEQ on vectors of unknown element type is
    substantially faster. (#902537)
  * optimization: specialized arrays with non-zero :INITIAL-ELEMENT
    can be stack-allocated. (#902351)
  * optimization: the compiler is smarter about representation
    selection for floating point constants used in full calls.
  * optimization: the compiler no longer refuses to coerce large
    fixnums to single floats inline, except on x86 where this
    limitation is still necessary.
  * bug fix: deadlock detection could report the same deadlock
    twice, for two different threads. Now a single deadlock is
    reported exactly once.
  * bug fix: interval-arithmetic division during type derivation
    did not account for signed zeros.
  * bug fix: compiler error when typechecking a call to a
    function with non-constant keyword arguments.
  * bug fix: misoptimization of TRUNCATE causing erratic behaviour.
  * bug fix: condition slot accessors no longer cause undefined
    function style-warnings when used in the :REPORT clause of
    the DEFINE-CONDITION form that defines them. (#896379)
  * bug fix: DEFGENERIC warns about unsupported declarations, as
    specified by ANSI. (#894202)
  * bug fix: SUBTYPEP tests involving forward-referenced classes
    no longer bogusly report NIL, T.
  * bug fix: bogus style-warnings for DEFMETHOD forms that both
    declared some required arguments ignored and performed
    assignments to others. (#898331)
  * bug fix: *EVALUATOR-MODE* :COMPILE treated (LET () ...)
    identically to (LOCALLY ...) leading to internally
    inconsistent toplevel-formness.
  * bug fix: non-toplevel DEFSTRUCT signaled a style warning for
    unknown type.
  * bug fix: redefining a function whose previous definition
    contained an unknown type no longer causes a style-warning. (#806243)
  * bug fix: undefined functions now appear in backtraces as
    ("undefined function") instead of ("bogus stack frame") on non-x86oids.
  * bug fix: backtraces are no longer cut off at ("undefined
    function") when called under certain circumstances (involving a
    caller-allocated stack frame) on PPC.
  * bug fix: RUN-PROGRAM leaked a file-descriptor per call on
    non-Windows systems. (regression since 1.0.53)
  * bug fix: GC deadlocks from dladdr() on certain platforms.
  * bug fix: broken standard streams no longer automatically
    cause recursive errors on debugger entry.
  * bug fix: build ignored --dynamic-space-size=<size> argument
    to (regression since 1.0.53)
  * bug fix: attempts to stack allocate a required argument to a
    function with an external entry point caused compiler-errors.
  * bug fix: compiler notes for failed stack allocation for a
    function argument no longer claim to be unable to stack
    allocate the function.
  * bug fix: COERCE now signals a type-error on several
    coercions to subtypes of CHARACTER that are forbidden
    according to ANSI. (#841312)
  * bug fix: missing failure-to-stack-allocate compiler notes
    for some forms of MAKE-ARRAY with dynamic-extent. (#902351)
  * bug fix: some of the compile-time side-effects of DEFCLASS
    were not caught by package locks.
