-changes relative to sbcl-1.0.54:
+changes relative to sbcl-1.1.2:
+ * bug fix: fasls are now once again directly executable (on platforms
+ supporting shebang lines, with a suitably-installed sbcl).
+
+changes in sbcl-1.1.2 relative to sbcl-1.1.1:
+ * notice: System requirements for SBCL on Microsoft Windows: Windows NT 5.1
+ or newer (Windows XP, Server 2003) is required. Support for Windows 2000
+ (NT 5.0) is no longer being maintained.
+ * notice: Starting with this version, SBCL on Windows no longer supports
+ building with disabled thread support.
+ * enhancement: frlocks have been added to SB-CONCURRENCY contrib module.
+ * enhancement: New feature sb-dynamic-core allows the runtime to be
+ rebuilt or relocated without requiring changes to the core file on
+ all linkage table platforms. Required on Windows. (Thanks to Anton
+ Kovalenko.)
+ * enhancement: Console I/O streams use UCS-2. (Thanks to Anton Kovalenko.)
+ * enhancement: I/O on Windows unnamed pipes is interruptible
+ asynchronously using interrupt-thread, timers when running on Windows NT
+ version 6.1 or newer (Windows 7, Server 2008 R2). (Thanks to Anton
+ Kovalenko.)
+ * enhancement: Support for the experimental safepoint-based stop-the-world
+ protocol on the PowerPC platform.
+ * bug fix: Non-blocking reads from the Windows console were not necessarily
+ non-blocking. Thanks to Anton Kovalenko. (lp#308923)
+ * bug fix: stability of threads on Windows has been improved upon through
+ an updated stop-the-world protocol (thanks to Anton Kovalenko).
+
+changes in sbcl-1.1.1 relative to sbcl-1.1.0:
+ * enhancement: WITH-COMPILATION-UNIT no longer grabs the world-lock.
+ (COMPILE and COMPILE-FILE still do.)
+ * optimization: the SPARC backend now supports the precise generational
+ (GENCGC) garbage collection. Enabled by default on Solaris/SPARC and
+ Linux/SPARC. Thanks to Raymond Toy (via CMUCL).
+ * enhancement: add experimental support for the SB-THREAD feature and the
+ timer facility on Windows. Thanks to Dmitry Kalyanov and Anton Kovalenko.
+ Threads are enabled by default, and this version of SBCL is considered
+ to be the last and final release to officially support building with
+ threads disabled.
+ * optimization: The compiler no longer rotates loops in some cases where
+ this transformation actually lead to worse code being generated.
+ * bug fix: SB-CLTL2:MACROEXPAND-ALL correctly handles shadowing of
+ symbol-macros by lexical bindings.
+ * bug fix: stack allocation was prevented by high DEBUG declaration in
+ several cases.
+ * bug fix: SB-EXT:GC-LOGFILE signaled an error when no logfile was set.
+ (thanks to SANO Masatoshi)
+ * bug fix: PARSE-NATIVE-NAMESTRING performed non-native parsing when
+ :JUNK-ALLOWED was true.
+ * bug fix: type derivation inferred overly conservative types for
+ unions of array types. (lp#1050768)
+
+changes in sbcl-1.1.0 relative to sbcl-1.0.58:
+ * enhancement: New variable, sb-ext:*disassemble-annotate* for controlling
+ source annotation of DISASSEMBLE output. Defaults to T.
+ * enhancement: TIMEOUT arguments added to WITH-MUTEX and WITH-RECURSIVE-LOCK, and
+ WAIT-P argument added to WITH-RECURSIVE-LOCK.
+ * enhancement: SB-EXT:ATOMIC-PUSH and SB-EXT:ATOMIC-POP allow atomic operations
+ on list heads.
+ * enhancement: Optional features (not enabled by default) allow the
+ use of signals for inter-thread synchronization to be reduced on certain
+ supported platforms (currently Linux, Solaris, and FreeBSD on x86 and
+ x86-64). Set (and :sb-thread :sb-safepoint :sb-thruption :sb-wtimer)
+ to test these experimental features. Known remaining bugs include minor
+ thread safety issues, less timely freeing of memory by GC, and certain
+ (not yet optimally low) runtime overhead. Thanks to Anton Kovalenko.
+ * optimization: CL:SORT and CL:STABLE-SORT of lists are faster and use fewer
+ comparisons, particularly on almost-sorted inputs.
+ * bug fix: Reading floats with large exponents no longer takes too much time
+ before reporting that the exponent is too large.
+ * bug fix: SB-BSD-SOCKETS:SOCKET-RECEIVE with a UDP socket now works
+ correctly when the received datagram is larger than the provided buffer.
+ (lp#1023438, thanks to Robert Uhl)
+ * bug fix: SB-EXT:GET-CAS-EXPANSION returned a bogus read-form when given
+ a SYMBOL-VALUE form with a constant symbol argument.
+ * bug fix: SB-EXT:GET-CAS-EXPANSION signaled an error when a macro expanding
+ into a DEFCAS defined place was used as the place.
+ * bug fix: FIND and POSITION signaled a type-error when non-bits where looked
+ for from bit-vectors.
+ * bug fix: a race condition around thread creation could (in SBCL 1.0.57)
+ lead to internal errors or crashes (lp#1058799).
+ * documentation: a section on random number generation has been added to the
+ manual. (lp#656839)
+
+changes in sbcl-1.0.58 relative to sbcl-1.0.57:
+ * enhancement: implicit generic function warnings now specify the package
+ in which the new generic function is being created.
+ * enhancement: SB-EXT:ATOMIC-UPDATE makes it easy to perform non-destructive
+ updates of CAS-able places (similar to Clojure's swap!).
+ * enhancement: run-program no longer decodes and re-encodes environment when
+ :environment argument is not provided. (lp#985904)
+ * enhancement: errors during compiler-macro expansion no longer cause
+ runtime errors, only a compile-time warning, otherwise behaving as if
+ the compiler macro had declined to expand.
+ * optimization: On x86-64, code alignment of block headers is done with
+ multi-byte NOPs now instead of repetitions of the single-byte NOP.
+ * optimization: MAP-INTO is substantially faster when the target sequence is
+ of unknown type; mapping into lists is no longer O(N^2). (lp#1001043,
+ thanks to James M. Lawrence)
+ * optimization: the compiler no longer heap-conses to check exits in cases
+ where the exit function is dynamic extent, or when it can prove the exit
+ function cannot escape. (lp#1002534)
+ * optimization: SB-SEQUENCE:DOSEQUENCE is faster on vectors of unknown
+ element type, and vectors that aren't SIMPLE-ARRAYs.
+ * optimization: CL:SORT and CL:STABLE-SORT are more efficient in execution
+ speed (around 1/3 the time in some cases), and a little better in terms of
+ comparison calls. (Thanks to Takeru Ohta)
+ * bug fix: On SPARC, a limitation on the number of code constants emittable
+ by the compiler has been lifted, allowing certain long functions to
+ compiled and assembled which had previously been unsupported; fixes
+ cl-bench on this ISA (lp#1008996).
+ * bug fix: potential for infinite recursion during compilation of CLOS slot
+ typechecks when dependency graph had loops. (lp#1001799)
+ * bug fix: error forms reported with some program-errors were not escaped
+ properly.
+ * bug fix: functions from EVAL are now on more equal footing with functions
+ from COMPILE. (lp#1000783, lp#851170, lp#922408)
+ * bug fix: ENSURE-GENERIC-METHOD-COMBINATION accepts method combination
+ objects as its :METHOD-COMBINATION argument, not just lists designating
+ method combinations. (lp#936513)
+ * bug fix: run-program no longer unconditionally uses /tmp/ for temporary
+ files. (lp#968837).
+ * bug fix: restore build on solaris/sparc. (lp#1008506)
+ * bug fix: an issue with LDB in the PowerPC backend has been resolved;
+ this fixes an issue found with cl-postgres (thanks to Tomas Hlavaty).
+ * bug fix: compiler-macro lambda-lists specifying non-keyword symbols
+ as keyword arguments no longer accidentally match unevaluated symbols
+ against them.
+ * bug fix: FORMAT used to loop infinitely in some cases when a COLINC
+ parameter was zero, now it signals an error. (lp#905817, fixed since
+ 1.0.56.19)
+ * bug fix: run-program with :pty t no longer makes the pty as the process's
+ controling terminal.
+ * bug fix: spawning threads on OS X 10.8 no longer crashes the process
+ (lp#1012811).
+
+changes in sbcl-1.0.57 relative to sbcl-1.0.56:
+ * RANDOM enhancements and bug fixes:
+ ** bug fix: the range and distribution of random integers could be
+ catastrophically wrong when the compiler derived the type of its
+ argument as a disjoint set of small integers.
+ ** bug fix: the distribution of random integers is now completely
+ uniform even when the specified limit is not a power of two.
+ (Previously some values could be about 0.1 % more probable than
+ others in the worst case.) (lp#309467)
+ ** RANDOM on large integer arguments is generally faster and conses
+ less than before; this is visible for fixnums above a length of
+ about 24 bits, but extremely so for bignums: the old implementation
+ used time and space quadratical in the size of the argument there,
+ the new one is linear.
+ * enhancement: redesigned protocol for quitting SBCL. SB-EXT:EXIT is the new
+ main entry point, SB-EXT:QUIT is deprecated.
+ * enhancement: additions to the SB-THREAD API: RETURN-FROM-THREAD,
+ ABORT-THREAD, MAIN-THREAD-P, and MAIN-THREAD.
+ * enhancement: FASL loading no longer grabs the world-lock.
+ * enhancement: GENCGC reclaims space more aggressively when objects being
+ allocated are a large fraction of the total available heap space.
+ (lp#936304)
+ * enhancement: backtraces show the correct number of arguments for frames
+ called with too many arguments.
+ * enhancement: support for abort(3), exit(3), and _exit(2) has been added to
+ SB-POSIX.
+ * enhancement: ASDF has been updated 2.21.
+ * optimization: fewer uses of full calls to signed modular functions.
+ (lp#903821)
+ * optimization: typechecking alien values is typically 5 x faster.
+ * optimization: FDEFINITION, SYMBOL-FUNCTION, MACRO-FUNCTION, and FBOUNDP
+ are 20% faster.
+ * bug fix: file compilation performance issues when dumping subtypes
+ of CHARACTER (lp#994487)
+ * bug fix: fixed disassembly of some SSE instructions on x86-64.
+ * bug fix: SB-SIMPLE-STREAMS signals an error for bogus :CLASS arguments in
+ OPEN. (lp#969352, thanks to Kambiz Darabi)
+ * bug fix: CASE normal-clauses do not allow T and OTHERWISE as keys.
+ (lp#959687)
+ * bug fix: (SETF (FIND-CLASS X) NIL) removed proper name of the underlying
+ classoid even if X was not the proper name of the class. (lp#941102)
+ * bug fix: declaration leakage between lexical environments due to careless
+ use of NCONC in MAKE-LEXENV. (lp#924276)
+ * bug fix: ENSURE-DIRECTORIES-EXIST now works when
+ *default-pathname-defaults* contains NAME or TYPE components.
+ * bug fix: PPRINT couldn't print improper lists with CARs being some symbols
+ from CL package, e.g. (loop . 10).
+ * bug fix: run-program with existent or non-existent files for :output or
+ :input when :if-output-exists or :if-input-does-not-exist are NIL properly
+ returns NIL instead of signalling an obscure error.
+ * bug fix: fix miscompilation of some logand forms with large constant
+ arguments. (lp#974406)
+ * bug fix: account for funcallable-instance objects properly in ROOM.
+ * bug fix: incorrect octets reported for c-string decoding errors.
+ (lp#985505)
+ * bug fix: miscompilation of LDB on the PowerPC platform. (thanks to Bruce
+ O'Neel)
+ * bug fix: better input error reporting for COMPILE-FILE. (lp#493380)
+ * bug fix: default size of non-nursery generations has been shrunk on GENCGC,
+ allowing faster release of memory back to the OS. (lp#991293)
+ * bug fix: WITH-DEADLINE (:SECONDS NIL :OVERRIDE T) now drops any
+ existing deadline for the dynamic scope of its body.
+ * bug fix: compiler-internal interval arithmetic needed to be more
+ conservative about open intervals when operated on by monotonic but not
+ strictly-monotonic functions. (lp#975528)
+ * bug fix: copy-tree caused stack exhaustion on long linear lists, and now
+ it's also slightly faster. (lp#998926)
+ * bug fix: better error messages for malformed declarations.
+ (lp#1000239)
+ * bug fix: define-condition didn't return the name of the defined condition.
+ * documentation:
+ ** improved docstrings: REPLACE (lp#965592)
+
+changes in sbcl-1.0.56 relative to sbcl-1.0.55:
+ * bug fix: fix copy-structure. When copying from stack to heap, garbage
+ could end up in the heap making GC unhappy.
+ (Thanks to James Knight, lp#911027)
+ * enhancements
+ ** SBCL can now be built using Clang.
+ ** ASDF has been updated 2.20.
+ * bug fix: compiler errors when weakening hairy integer types. (lp#913232)
+ * bug fix: don't complain about a too-hairy lexical environment for inlining
+ when the function has never been requested for inlining. (lp#963530)
+
+changes in sbcl-1.0.55 relative to sbcl-1.0.54:
* enhancements to building SBCL using make.sh:
** --fancy can be specified to enable all supported feature enhancements.
** --with-<feature> and --without-<feature> can be used to specify
* enhancement: SBCL now provides either an explicit :BIG-ENDIAN or
:LITTLE-ENDIAN in *FEATURES*, instead of :BIG-ENDIAN being implied by lack
of the :LITTLE-ENDIAN feature. (Thanks to Luís Oliveira, lp#901661)
+ * enhancement: better disassembly of segment-prefixes on x86 and other
+ instruction prefixes (e.g. LOCK) on x86 and x86-64.
+ * optimization: FIND and POSITION on bit-vectors are orders of magnitude
+ faster (assuming KEY and TEST are not used, or are sufficiently trivial.)
* optimization: SUBSEQ on vectors of unknown element type is substantially
faster. (lp#902537)
* optimization: specialized arrays with non-zero :INITIAL-ELEMENT can
- be stack-allocated. (lp#902351)
+ be stack-allocated. (lp#902351)
* optimization: the compiler is smarter about representation selection for
floating point constants used in full calls.
* optimization: the compiler no longer refuses to coerce large fixnums to
single floats inline, except on x86 where this limitation is still
necessary.
+ * optimization: truncation operations on integers with constant divisor
+ arguments 1 and -1 are optimized away.
* bug fix: deadlock detection could report the same deadlock twice, for
two different threads. Now a single deadlock is reported exactly once.
* bug fix: interval-arithmetic division during type derivation did not
subtypes of CHARACTER that are forbidden according to ANSI. (lp#841312)
* bug fix: missing failure-to-stack-allocate compiler notes for some
forms of MAKE-ARRAY with dynamic-extent. (lp#902351)
+ * bug fix: some of the compile-time side-effects of DEFCLASS were not caught
+ by package locks.
+ * bug fix: Proper handling of --dynamic-space-size option on 32 bit platforms.
