+ * bug 75 fix: WITH-OUTPUT-TO-STRING (and MAKE-STRING-OUTPUT-STREAM)
+ now accept and act upon their :ELEMENT-TYPE keyword argument.
(reported by Martin Atzmueller, Edi Weitz)
* bug fix: FILE-POSITION now accepts position designators up to
ARRAY-DIMENSION-LIMIT or the extreme of the off_t range, whichever
target sequence. (thanks to Gerd Moellmann)
* bug fix in threaded builds: the system can now be suspended and
resumed by shell job control with minimal disruption.
+ * bug fixes in times and timezones >2038AD
+ * better handling of "where is GNU make?" problem in build scripts
+ (thanks to Nikodemus Siivola)
* new optimization: inside a named function any reference to a
function with the same name is considered to be a self-reference;
this behaviour is controlled with SB-C::RECOGNIZE-SELF-CALLS
* new optimization on x86: logical functions and + now have
optimized (UNSIGNED-BYTE 32) versions, which are automatically
used when the result is truncated to 32 bits.
+ * VALUES declaration is partially enabled.
+ * fixes in SB-GROVEL (thanks to Andreas Fuchs)
* fixed some bugs revealed by Paul Dietz' test suite:
** The system now obeys the constraint imposed by
UPGRADED-ARRAY-ELEMENT-TYPE that the upgraded array element
** ASSOC now ignores NIL elements in an alist.
** CEILING now gives the right answer with MOST-NEGATIVE-FIXNUM
and (1+ MOST-POSITIVE-FIXNUM) answers.
+ ** The addition of a method with invalid qualifiers to a generic
+ function does not cause an error to be signalled immediately;
+ a warning is signalled, and the error is generated only on
+ calling the generic function.
+ * changed .fasl file version number, in part to add type codes for
+ new array subtypes UNSIGNED-BYTE 7, 15, 29, and 31 mandated by
+ obscure ANSI requirements
+
+changes in sbcl-0.8.4 relative to sbcl-0.8.3:
+ * fixed compiler performance when processing loops with a step >1;
+ * bug fix: DOCUMENTATION now retrieves generic function
+ documentation. Also, DOCUMENTATION and (SETF DOCUMENTATION)
+ support has been systematized, and now supports the methods
+ specified by ANSI, along with a default method and a method for
+ slot documentation. (reported by Nathan Froyd)
+ * bug fix: effective methods associated with a generic function are
+ no longer cached over a change of that generic function's method
+ combination. (reported by Andreas Fuchs)
+ * bug fix: RUN-PROGRAM now does not fail if some element in $PATH
+ names a non-existent directory. (thanks to Andreas Fuchs)
+ * bug fix: ROUND and TRUNCATE could, under certain circumstances on
+ the PPC platform, lead to stack corruption; this has been fixed.
+ (reported by Rainer Joswig)
+ * bug fix: ASH on an (UNSIGNED-BYTE 32) with a shift of -32 or lower
+ no longer ever returns 1 instead of 0. (thanks to Lars Brinkhoff)
+ * fixed bug 285: TRUNCATE on bignum arguments, and indeed bignum
+ arithmetic in general, is now much more reliable on the PPC
+ platform.
+ * optimization: restored some effective method precomputation in
+ CLOS (turned off by an ANSI fix in sbcl-0.8.3); the amount of
+ precomputation is now tunable.
+ * optimization: compiler-internal data structure use has been
+ reviewed, and changes have been made that should improve the
+ performance of the compiler by about 20%.
+ * optimization: performance of FILL (and :INITIAL-ELEMENT) on
+ simple-base-strings and simple-bit-vectors is improved.
+ * microoptimization: the compiler is better able to make use of the
+ x86 LEA instruction for multiplication by constants.
+ * bug fix: in some situations compiler did not report usage of
+ generic arithmetic in (SPEED 3) policy.
+ * bug 145b fix: compiler used wrong type specifier while converting
+ MEMBER-types to numeric.
+ * fixed some bugs revealed by Paul Dietz' test suite:
+ ** the RETURN clause in LOOP is now equivalent to DO (RETURN ...).
+ ** ROUND and FROUND now give the right answer when given very
+ small float arguments.
+ ** (FLOAT X) for X of type DOUBLE-FLOAT now returns X in all
+ circumstances.
+ ** optimizer for (EXPT X 0) did not work for X not of type FLOAT.
+ ** (GCD 0 <negative-integer>) returned <negative-integer>.
+ ** LCM should return a non-negative integer.
+ ** PARSE-INTEGER returned the index of a terminator instead of the
+ upper bounding index of a substring in case :JUNK-ALLOWED NIL.
+ ** PARSE-INTEGER returned an incorrect index being applied to a
+ displaced string.
+ ** LCM with two arguments of 0 returns 0 rather than signalling
+ DIVISION-BY-ZERO.
+ ** unsigned addition of a 32-bit constant with the high bit set no
+ longer causes an internal compiler error on the x86.
+ ** LOGBITP accepts a non-negative bignum as its INDEX argument.
+ ** compiler incorrectly derived types of DPB and DEPOSIT-FIELD
+ with negative last argument.
+ ** byte specifiers with zero size and position no longer cause
+ an error during type derivation.
