(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.
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
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.
planned incompatible changes in 0.8.x:
* (not done yet, but planned:) When the profiling interface settles
