+changes relative to sbcl-1.0.31
+ * optimization: faster FIND and POSITION on strings of unknown element type
+ in high SPEED policies. (thanks to Karol Swietlicki)
+ * optimization: faster CONCATENATE 'STRING in low SPEED policies (reported
+ by David Vázquez)
+ * improvement: better error signalling for bogus parameter specializer names
+ in DEFMETHOD forms (reported by Pluijzer)
+ * bug fix: SAVE-LISP-AND-DIE option :SAVE-RUNTIME-OPTIONS did not work
+ correctly when starting from an executable core without saved runtime
+ options (reported by Faré Rideau, thanks to Zach Beane)
+ * bug fix: (SETF SLOT-VALUE) signalled a warning which should have been
+ an optimization note instead. (reported by Martin Cracauer)
+ * bug fix: WITH-SLOTS did not work with THE forms. (thanks to David Tolpin)
+
+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
* 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.
+ 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 expansions could
be miscompiled if the result was declared to be dynamic extent.
+ * bug fix: on x86, SAP-REF of sizes greater than 8 bits with offsets of the
+ form (+ <variable> <integer>) were miscompiled under certain
+ circumstances.
* bug fix: in some cases no compiler note about failure to stack allocate
was emitted, even if the objects were in fact heap allocated.
* bug fix: minor violation of "otherwise inaccessible" rule for stack
be heap allocated to be stack allocated.
* bug fix: DESCRIBE signalled an error for generic functions under
certain circumstances. (thanks to Leslie Polzer)
+ * bug fix: Fixed spelling of an error message.
