Subject: SBCL 1.0.31 released
Newsgroups: gmane.lisp.steel-bank.announce
Date: Thursday 27th August 2009 20:43:25 UTC (over 9 years ago)
Hi,

I've just released and tagged sbcl-1.0.31.  I've also interacted with
yet another new SourceForge file release system; if something is odd
with the released files, please let me know.

Best wishes,

Christophe

changes in sbcl-1.0.31 relative to sbcl-1.0.30:
  * improvement: stack allocation is should now be possible in all nested
    inlining cases: failure to stack allocate when equivalent code is
manually
    open coded is now considered a bug.
  * improvements related to Unicode: 
    ** the Unicode character database has been upgraded to the
       Unicode 5.1 standard, giving names and properties to a number of new
       characters, and providing a few extra characters with case
       transformations.
    ** the system now recognizes and produces names for Unicode Hangul 
       syllable characters.
    ** the EBCDIC-US external-format is now supported for octet operations
       (as well as for stream operations).
  * new feature: experimental :EMIT-CFASL parameter to COMPILE-FILE can
    be used to output toplevel compile-time effects into a separate .CFASL
    file.
  * optimization: COERCE to VECTOR, STRING, SIMPLE-STRING and recognizable
    one-dimenstional subtypes of ARRAY is upto 70% faster when the coercion
is
    actually needed.
  * optimization: TRUNCATE on known single- and double-floats is upto 25%
    faster.
  * optimization: division of floating point numbers by constants uses
    multiplication by reciprocal when an exact reciprocal exists.
  * optimization: multiplication of single- and double-floats floats by
    constant two has been optimized.
  * optimization: ARRAY-IN-BOUNDS-P is resolved at compile-time when
    sufficient type information is available. (thanks to Leslie Polzer)
  * optimization: SLOT-VALUE and (SETF SLOT-VALUE) with constant slot names
on
    known structure objects are as efficient as defstruct generated
accessors.
  * optimization: unused vector creation can now be optimized away.
  * improvement: ASDF systems can now depends on SB-INTROSPECT.
  * improvement: a STYLE-WARNING is signalled when a generic function
    clobbers an earlier FTYPE proclamation.
  * improvement: the compiler is able to track the effective type of
    generic function across method addition and removal even in the
    absence of an explicit DEFGENERIC.
  * improvement: DESCRIBE now reports on symbols naming undefined
    but assumed or declared function as well.
  * improvement: recompilation of systems using SB-GROVEL now works
    (thanks to Leslie Polzer)
  * improvements to SB-CLTL2 (thanks to Larry D'Anna):
    ** functions DECLARATION-INFORMATION, PARSE-MACRO, and ENCLOSE have
been
       documented.
    ** AUGMENT-ENVIRONMENT and DEFINE-DECLARATION have been implemented.
    ** DECLARATION-INFORMATION now supports declaration name DECLARATION as
       well as user defined declaration names.
    ** VARIABLE-INFORMATION is now aware of alien variables.
  * improvement: improved address space layout on OpenBSD (thanks to Josh
    Elsasser)
  * improvement: pretty-printing of various Lisp forms has been improved
    (thanks to Tobias Rittweiler)
  * bug fix: calls to DECODE-FLOAT and INTEGER-DECODE-FLOAT whose value was
    unused were deleted in safe code. (reported by John Fremlin)
  * bug fix: a failing AVER compiling certain MAKE-ARRAY forms. (reported
    by James Wright)
  * bug fix: some out-of-line array predicates were missing (reported by
    Stelian Ionescu)
  * bug fix: a failing AVER in CONVERT-MV-CALL has been fixed. (thanks to
    Larry D'Anna)
  * bug fix: a failing AVER in %ALLOCATE-CLOSURES conversion has been fixed
    (thanks to Larry D'Anna)
  * bug fix: SLEEP supports times over 100 million seconds on long on
OpenBSD
    as well. (reported by Josh Elsasser)
  * bug fix: DELETE-FILE on streams no longer closes the stream with :ABORT
T,
    leading to possible attempts to delete the same file twice. See
docstring
    on DELETE-FILE for details. (reported by John Fremlin)
  * bug fix: DELETE-FILE once again deletes the file named by the pathname
    designator argument, rather than its truename.  (reported by Luis
    Oliveira)
  * bug fix: the low-level debugger had 32-bit assumptions and was missing
    information about some array types. (thanks to Luis Oliveira)
  * bug fix: moderately complex combinations of inline expa
