+changes 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.
+ * improvement: 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.
+ * improvement: the system now recognizes and produces names for Unicode
+ Hangul syllable characters.
+ * 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: 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: 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: 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
+ allocation could cause objects users might reasonably expect to
+ 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.
+
+changes in sbcl-1.0.30 relative to sbcl-1.0.29:
+ * minor incompatible change: SB-THREAD:JOIN-THREAD-ERROR-THREAD and
+ SB-THREAD:INTERRUPT-THREAD-ERROR-THREAD have been deprecated in favor
+ of SB-THREAD:THREAD-ERROR-THREAD.
+ * new contrib module: SB-QUEUE provides thread-safe lockless FIFO queues.
+ * new feature: docstrings for local and anonymous functions are no longer
+ discarded. (thanks to Leslie Polzer)
+ * new feature: SB-THREAD:SYMBOL-VALUE-IN-THREAD provides access to symbol
+ values in other threads.
+ * new feature: SB-INTROSPECT:ALLOCATION-INFORMATION provides information
+ about object allocation.
+ * optimization: division of a real float by a complex float is implemented
+ with a specialised code sequence.
+ * optimization: MAKE-INSTANCE with non-constant class-argument but constant
+ keywords is an order of magnitude faster.
+ * optimization: MAKE-INSTANCE with constant keyword arguments is x2-4 faster
+ in the presence of :AROUND or non-standard primary INITIALIZE-INSTANCE
+ methods, and similarly for non-standard metaclass classes as long as there
+ are no methods additional on MAKE-INSTANCE.
* optimization: more efficient type-checks for FIXNUMs when the value
is known to be a signed word on x86 and x86-64.
+ * optimization: compiler now optimizes (EXPT -1 INTEGER), (EXPT -1.0 INTEGER),
+ and (EXPT -1.0d0 INTEGER) into an ODDP test. (thanks to Stas Boukarev and
+ Paul Khuong)
+ * optimization: compiler is smarter about delegating argument type checks to
+ callees.
+ * optimization: several character functions are now compiled somewhat more
+ efficiently. (reported by Lynn Quam)
+ * optimization: the compiler now derives simple types for LOAD-VALUE-FORMs.
+ * improvement: less unsafe constant folding in floating point arithmetic,
+ especially for mixed complex/real -float operations.
+ * optimization: constant double and single floats are stored in native
+ unboxed format on x86[-64].
+ * optimization: smarter code for arithmetic operations with constant floats,
+ complex floats, or integers on x86[-64].
+ * optimization: smarter code for conjugate/multiplication of float complexes
+ and abs/negate of floats on x86-64.
+ * optimization: more efficient complex float and real float operations on
+ x86-64.
+ * improvement: complex float division is slightly more stable.
+ * improvement: DESCRIBE output has been reworked to be easier to read and
+ contains more pertinent information.
* improvement: failure to provide requested stack allocation compiler notes
provided in all cases (requested stack allocation not happening without a
note being issued is now considered a bug.)
+ * bug fix: SB-POSIX exports the documented types and functions
+ FILE-DESCRIPTOR and FILENAME, and also the corresponding -DESCRIPTOR
+ types. (reported by "abhi")
* bug fix: on 64 bit platforms FILL worked incorrectly on arrays with
upgraded element type (COMPLEX SINGLE-FLOAT), regression from 1.0.28.55.
(thanks to Paul Khuong)
* bug fix: better error signalling when calls to functions seeking elements
from lists (eg. ADJOIN) are compiled with both :TEST and :TEST-NOT.
(reported by Tobias Rittweiler)
+ * bug fix: regressions in DIRECTORY from 1.0.28.61: pattern matching of
+ directory components now works as it used to. (various prolems reported by
+ Michael Becker, Gabriel Dos Reis, Cyrus Harmon, and Harald Hanche-Olsen)
+ * bug fix: :PTY option in RUN-PROGRAM was broken with stream arguments.
+ (reported by Elliot Slaughter, thanks to Stas Boukarev)
+ * bug fix: bogus undefined variable warnings from fopcompiled references to
+ global variables. (thanks to Lars Rune Nøstdal)
+ * bug fix: foreign function names should now appear in backtraces on
+ FC6 as well. (reported by Tomasz Skutnik and Tobias Rautenkranz)
+ * bug fix: SETF compiler macro documentation strings are not discarded
+ anymore.
+ * bug fix: GENTEMP is now unaffected by pretty printer dispatch table.
+ (thanks to Alex Plotnick)
+ * bug fix: SLEEP accepts large integer arguments, truncating them to
+ SIGNED-WORD on the assumption that sleeping for 68 years is sufficient
+ for anyone. (reported by Leslie Polzer, thanks to Stas Boukarev)
+ * bug fix: compiler notes for expensive slot type checks could be emitted
+ at runtime MAKE-INSTANCE calls. (reported by Samium Gromoff)
