sbcl-1.1.8 released
http://comments.gmane.org/gmane.lisp.steel-bank.announce/146
<pre>Dear all,
Thanks to those who responded to my call for testing. I took the
opportunity to do a live release of sbcl-1.1.8 at the European Common
Lisp Meeting, perhaps a little bit ahead of schedule; worthy of note
this month, as well as the particularly large number of changes, is that
several of them are from new contributors. The excitingly numerous
notes for this release are appended to this message.
Best wishes,
Christophe
changes in sbcl-1.1.8 relative to sbcl-1.1.7:
* notice: The implementation of MAP-ALLOCATED-OBJECTS (the heart of
ROOM, plus a few SB-INTROSPECT functions) has been completely
rewritten; it may now exhibit different bugs than before.
* new feature: minimal runtime/compiler intrastructure support for SSE
SIMD values, as SB-EXT:SIMD-PACK. Enabled on x86-64 via the build-time
feature :sb-simd-pack. This should enable intrinsics extensions as
libraries, without patching SBCL itself. Thanks to Alexander Gavrilov
for maintaining a branch for so long.
* enhancement: RUN-PROGRAM supports a :DIRECTORY argument to set
the working directory of the spawned process.
(lp#791800) (patch by Matthias Benkard)
* enhancement: boxed vectors (vectors of T or of FIXNUM) can now be
stack-allocated on PPC.
* enhancement: "fixed objects" can now be stack-allocated on PPC.
* enhancement: WITH-PINNED-OBJECTS no longer conses on PPC/GENCGC.
* enhancement: (sb-introspect:find-definition-sources-by-name x :vop) now
also returns VOPs which do not translate any functions, and finds
defoptimizer types ir2convert and stack-allocate-result.
* enhancement: better type derivation for APPEND, NCONC, LIST.
(lp#538957)
* enhancement: MAP-ALLOCATED-OBJECTS (the heart of ROOM) now walks the
heap in a manner similar to the GC rather than its previous ad-hoc
scheme, and is therefore no less and possibly more accurate.
* fixes and enhancements related to Unicode:
** the character database information has been updated to Unicode 6.2;
** support for canonical and compatibility decomposition of characters has
been added, along with support for primary composition;
** support for Unicode normalization forms of strings (NFC, NFKC, NFD and
NFKD) has been included;
** querying the character database for code points not defined by Unicode
gives less wrong answers (lp#1178038, reported by Ken Harris)
* enhancement: print intermediate evaluation results for some ASSERTed
expressions. (lp#789497) (patch by Alexandra Barchunova)
* enhancement: x86-64 disassemblies are annotated with unboxed constant
values when there are references to (RIP-relative) unboxed constants.
* bug fix: type derivation for LOG{AND,IOR,XOR} scales linearly instead
of quadratically with the size of the input in the worst case.
(lp#1096444)
* bug fix: handle errors when initializing *default-pathname-defaults*,
sb-ext:*runtime-pathname*, sb-ext:*posix-argv* on startup, like character
decoding errors, or directories being deleted.
* bug fix: Loading a core with a discontiguous dynamic space now correctly
computes the amount of dynamic space used.
* bug fix: disassembler missing ",8" on SHLD
* bug fix: backtracing through INTERNAL-ERROR signal handlers on systems
that provide an "invalid" stack frame link for the signal handler
itself now use the saved-fp-and-pc mechanism to pick up from the stack
frame in the interrupt (signal) context. This is known to affect
threaded FreeBSD/x86-64.
* bug fix: some LOOP statements couldn't be compiled.
(lp#1178989)
* bug fix: sb-sequence:dosequence works on literal vectors.
* bug fix: errors in generic arithmetic show the assembly routine's
caller on x86 and x86-64. (lp#800343)
* bug fix: Compile-time type errors should never result in COMPILE-FILE
failure. (lp#943953)
* bug fix: Known bad local calls do not cause strange failures when
emitting or dumping code. (lp#504121)
* bug fix: Multiply-inlined structure constructor don't cause IR2-time
codegen errors: type checks are inserted as necessary. (lp#1177703)
* bug fix: Unsigned modular arithmetic is correctly converted into signed
modular arithemtic (mostly to exploit fixnum-width VOPs). (lp#1026634)
* bug fix: a combination of inlined local function with &optional and
recursion no longer causes undescriptive compiler errors. (lp#1180992)
* bug fix: sub-word BOOLEAN alien types now disregard higher order bits
when testing for non-zero-ness.
* bug fix: (CONCATENATE 'null ...) no longer fails for generic sequences.
(lp#1162301)
* bug fix: Type mismatch for the value of conditional expressions are
correctly reported when detected at compile-time, instead of complaining
about a constant NIL (similar for non-EQ-comparable catch tags).
* bug fix: Referring to INLINE global functions as values should not result
in a compilation failure. (lp#1035721)
* optimization: faster ISQRT on fixnums and small bignums
* optimization: faster and smaller INTEGER-LENGTH on fixnums on x86-64.
* optimization: On x86-64, the number of multi-byte NOP instructions used
for code alignment is now always minimal.
* optimization: On 64-bit targets, the compiler generates much faster
code for type checks for types known at compile time that are smaller
than (SIGNED-BYTE 64) or (UNSIGNED-BYTE 64) and larger than FIXNUM, and
their COMPLEX variants.
* optimization: On x86 targets, more uses of ALIEN-FUNCALL during cross
compilation now inline the INVOKE-WITH-SAVED-FP-AND-PC dance.
* optimization: ROOM no longer conses so egregiously on non-x86oid
systems.
* optimization: associative bitwise operations reassociate patterns like
(f (f x k1) k2) to expose (f x (f k1 k2)). Same for + and * of
rational values.
* optimization: quasiquote expressions now perform more constant folding,
instead of consing equal lists at runtime. (lp#1026439)
* optimization: local call analysis of inlined higher-order function
should converge more quickly, resulting in better code for complex
functions.
* optimization: On x86-64, medium (word-sized but wider than 32 bits)
integer constants are handled more cleverly, especially when they
can be represented as sign-extended (signed-byte 32). (Based on a
patch by Douglas Katzman)
* optimization: IF/IF conversion should reliably result in sane code
when (some of) the results of the inner IF are always false or
always true.
* optimization: On x86oids, variable right shifts of machine words are
compiled into straight SAR/SHR, instead of going through the generic
VOP. (lp#1066204)

</pre>Christophe Rhodes2013-06-02T16:10:36release candidate for sbcl-1.1.8
http://comments.gmane.org/gmane.lisp.steel-bank.announce/145
<pre>Dear all,
As something of an experiment, after a very busy month of development
and a short freeze period, I'm making available a release candidate
rather than pressing directly ahead with the release: a number of
subsystems saw some moderately invasive changes, and while the
regression test suite we have exercises a lot of code paths, more
real-world testing would increase my confidence in the system.
Therefore, I would appreciate it if people could test the current HEAD
in the git repository, and verify that it functions as expected for
their workload. I've put a tarball of the source code at
<http://www.doc.gold.ac.uk/~mas01cr/tmp/sbcl-1.1.7-116-g17dd0a1-source.tar.gz>,
and an x86-64/linux binary at
<http://www.doc.gold.ac.uk/~mas01cr/tmp/sbcl-1.1.7-116-g17dd0a1-binary.tar.bz2>.
Reports to sbcl-devel (or to me personally), particularly of any
libraries or applications which do not seem to function as expected,
would be much appreciated; absent indications to the contrary, I would
hope to make the release early next week.
Best wishes,
Christophe

</pre>Christophe Rhodes2013-05-29T16:42:06sbcl-1.1.7 released
http://comments.gmane.org/gmane.lisp.steel-bank.announce/144
<pre>Dear all,
I have just released sbcl-1.1.7; release notes are appended to this
message. Share and enjoy.
Best wishes,
Christophe
changes in sbcl-1.1.7 relative to sbcl-1.1.6:
* enhancement: TRACE :PRINT-ALL handles multiple-valued forms.
(lp#457053)
* bug fix: :allocation slot option works for condition slots
(lp#1049404)
* bug fix: redefining conditions does not lead to multiple evaluations of
hairy slot initfunctions anymore (lp#1164969)
* bug fix: CLASS-DIRECT-DEFAULT-INITARGS now works for condition classes
(lp#1164970)
* bug fix: function constants now work as initforms and default initarg
values of conditions (lp#539517)
* bug fix: svref/(setf svref) on symbol macros don't crash the compiler
anymore. (Minimal test case provided by James M. Lawrence on sbcl-devel)
* bug fix: no more bogus ## references when pretty printing backquoted
forms with non-trivial structure sharing. (lp#1161218)
* bug fix: Don't signal an error on (setf (documentation nil 'function)
"doc"). Signal a style-warning instead when trying to set documentation
of NIL for all other documentation types. (Reported by Zach
Beane; regression since 2e52fa05.)
* bug fix: modular arithmetic involving large constants and conditionals
should no longer result in spurious dead code elimination. (Reported by
Eric Marsden).
* bug fix: our mach exception handler can seemingly called very early in
the program execution process on OS X 10.8.0. Try and handle that case
robustly, without potentially leaking mach ports too much.
* optimization: LOGBITP and LOGTEST optimizations from x86 ported to x86_64.

</pre>Christophe Rhodes2013-04-29T16:22:42sbcl-1.1.6 released
http://comments.gmane.org/gmane.lisp.steel-bank.announce/142
<pre>Dear all,
I've just released sbcl-1.1.6. There have been reports about some
concurrency tests failing on windows, and some garbage collection
troubles on PowerPC/Linux with the generational garbage collector: users
of those particular systems may wish to exercise extra care in
upgrading, though it's not clear that either of these issues is a
regression.
Changes from sbcl-1.1.5 are appended to this message.
Best wishes,
Christophe
changes in sbcl-1.1.6 relative to sbcl-1.1.5:
* enhancement: the continuable error when defknown-ing over extant
fndb entries can be ignored by passing :overwrite-fndb-silently t
as a keyword argument to sb-c:defknown (after attributes). Useful
to allow defknown to be re-loaded. Use with :allow-other-keys t
for backward compatibility.
* optimization: compiler is much faster in compiling SVREF and (SETF SVREF)
forms.
* bug fix: Prevent a make-array transform from modifying source forms
causing problems for inlined code. Thanks to Bart Botta.
(regression since 1.0.42.11-bis)
* bug fix: clear-output calls the correct gray stream routine,
sb-gray:stream-clear-output. (lp#1153257)
* bug fix: an error is signalled for an invalid format modifier: ~<~< at >>.
(lp#1153148)
* bug fix: Better error messages for package operations (lp#1154776)
* bug fix: delete-package on a nonexistent package should signal a cerror.
(regression since 1.0.37.44).
* bug fix: accessing &MORE (stack allocated &REST) arguments checks bounds.
(lp#1154946, lp#1072112)
* bug fix: compiling make-array no longer signals an error when the
element-type is an uknown type, a warning is issued instead.
Thanks to James Kalenius (lp#1156095)
* bug fix: SEARCH on generic (non-VECTOR non-LIST) sequence types no longer
produces wrong results for some inputs. (Thanks to Jan Moringen.)

</pre>Christophe Rhodes2013-03-29T20:21:29sbcl-1.1.5 released
http://comments.gmane.org/gmane.lisp.steel-bank.announce/141
<pre>Dear all,
I've just released sbcl-1.1.5 in git and to sourceforge; as usual,
binaries for various platforms will trickle in over the next few days.
The release notes are appended to this message.
Best wishes,
Christophe
changes in sbcl-1.1.5 relative to sbcl-1.1.4:
* minor incompatible change: SB-SPROF:WITH-PROFILING no longer loops
by default.
* new feature: package local nicknames. See manual for details.
* new feature: SB-EXT:MAP-DIRECTORY provides a powerful interface for
directory traversal: it is the backend used by SBCL for CL:DIRECTORY.
* enhancement: easier to use restarts for resolving name-conflicts
resulting from IMPORT, EXPORT, or USE-PACKAGE.
* enhancement: variant DEFPACKAGE forms now signal a full error with
restarts provided for resolving the situation. (lp#891351)
* enhancement: by setting SB-EXT:*ON-PACKAGE-VARIANCE* appropriately variant
DEFPACKAGE forms can now signal a full error with restarts provided for
resolving the situation. See manual for details. (lp#891351)
* enhancement: make-random-state now uses CryptGenRandom as a seed on Windows.
(Thanks to Anton Kovalenko.) (lp#1102748)
* enhancement: backtrace improvements
** secondary CLOS dispatch functions have better debug names (lp#503081)
** easier to read method names in backtraces. See
SB-DEBUG:*METHOD-FRAME-STYLE*.
** SB-DEBUG:PRINT-BACKTRACE and SB-DEBUG:LIST-BACKTRACE are available as
forwards-compatible replacements for SB-DEBUG:BACKTRACE and
SB-DEBUG:BACKTRACE-AS-LIST.
** SB-DEBUG:*SHOW-ENTRY-POINT-DETAILS** has been deprecated, as the same
information is available in less intrusive form as frame annotations.
* enhancement: SB-POSIX now provides MAP-ANON.
* enhancement: test-suite results are colorized, failures in red, unexpected
success in green. Works on Windows and on terminals with ANSI escape code
support. Can be disabled with --no-color.
* optimization: SB-CONCURRENCY:QUEUE implementation is more efficient.
(thanks to James M. Lawrence)
* bug fix: no more unused variable style warnings from RESTART-CASE
macroexpansion (lp#1113859)
* bug fix: no more unused variable style warnings when loading
sb-bsd-sockets.asd (lp#1114681)
* bug fix: deleting a package removes it from implementation-package
lists of other packages.
* bug fix: SB-SPROF:WITH-PROFILING is now usable in the Slime REPL on Darwin.
This does not fix the occasional "interrupt already pending" issue, though.
* bug fix: (setf (documentation 'x 'function)) and
(setf (documentation #'x t)) set documentation in different places.
(regression since 1.0.43.63)
* bug fix: build on newer glibc. (lp#1095036)

</pre>Christophe Rhodes2013-02-26T13:18:02sbcl-1.1.4 released
http://comments.gmane.org/gmane.lisp.steel-bank.announce/140
<pre>Just in time for the end of the month, I have released sbcl-1.1.4. Of
note, the sb-sprof contrib will now not fail its self-tests on Darwin
any more, unlike sbcl-1.1.3; this does not mean that the underlying
signal-related issue has been fixed, merely that the test has been
disabled on that platform to allow the somewhat fragile utility to
nevertheless be available for users.
I have appended the release notes below.
Best wishes,
Christophe
changes in sbcl-1.1.4 relative to sbcl-1.1.3:
* optimization: LOOP expressions using "of-type character" have slightly
more efficient expansions.
* bug fix: very long (or infinite) constant lists in DOLIST do not result
in very long compile times or heap exhaustion anymore. (lp#1095488)
* bug fix: `#3(1) is read as #(1 1 1), not as #(1). (lp#1095918)
* bug fix: adjust-array ignored :initial-element for simple-vectors.
(lp#1096359)
* bug fix: optimizations to MAKE-INSTANCE with literal list initargs no
longer cause infinite loops (on circular data) or violate eqlity
constraints. (lp#1099708)
* bug fix: FIRST was not being open coded. (regression from 1.1.0)

</pre>Christophe Rhodes2013-01-30T21:04:49sbcl-1.1.3 released
http://comments.gmane.org/gmane.lisp.steel-bank.announce/139
<pre>Dear all,
I have just performed the release dance for SBCL 1.1.3. Do please note
that there has been a report of a regression in the display of
backtraces when an interrupt happens during condition-wait on OS X -- if
this affects you and you can help reproduce or isolate the problem, that
would be most helpful. Otherwise, the release notes are appended to
this message; we would be interested in feedback, particularly from
Windows users (as the mainline approaches some of the functionality of
Anton Kovalenko's fork).
Happy New Year,
Christophe
changes in sbcl-1.1.3 relative to sbcl-1.1.2:
* enhancement: warnings about bad locale settings, LANG, LC_CTYPE, etc.
(lp#727625)
* enhancement: support for C-c to interrupt the foreground thread
on Windows. (Thanks to Anton Kovalenko.)
* enhancement: STDCALL alien callbacks. (Thanks to Anton Kovalenko.)
* enhancement: Safepoint builds on POSIX platforms can now optionally be
built without pseudo-atomic sequences and their run-time overhead.
* enhancement: Threads created outside of Lisp can enter Lisp through
alien callbacks and appear as Lisp threads for the duration of that
function invocation. On safepoint builds only.
* enhancement: Miscellaneous improvements to namestrings and underlying
calls to OS functions for file system access on Windows. (Thanks to
Anton Kovalenko.)
* enhancement: The MSI installer support for Windows now uses Windows
Installer XML at least version 3.5 and includes various usability
improvements. (Thanks to Dmitry Kalyanov and Anton Kovalenko.)
* enhancement: The sb-bsd-sockets contrib now supports non-blocking-mode
on Windows. (Thanks to Anton Kovalenko.)
* enhancement: The Windows backend now supports the x86-64 platform.
(Thanks to Anton Kovalenko.)
* bug fix: fasls are now once again directly executable (on platforms
supporting shebang lines, with a suitably-installed sbcl).
* bug fix: make.sh --help no longer runs clean.sh. (lp#937001)
* bug fix: Fix CAS access to slots of direct instances of structure classes
in the presence of subclasses sharing the same conc-name.
* bug fix: Logical pathname namestrings on Windows have been changed to
be lower-case, to minimize differences between POSIX and Windows.

http://comments.gmane.org/gmane.lisp.steel-bank.announce/138
<pre>Dear all,
I have just done the release dance for sbcl-1.1.2; an x86-64/Linux
binary (and the source code) are now available at sourceforge. The
release notes are appended to this message; please consume responsibly,
taking particular note of the new arrangements on Windows.
Best wishes,
Christophe
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).

</pre>Christophe Rhodes2012-12-01T14:25:15sbcl-1.1.1 released
http://comments.gmane.org/gmane.lisp.steel-bank.announce/137
<pre>Dear all,
I've just released sbcl-1.1.1. A couple of things to note: firstly
there have been some reports of heap corruption under some circumstances
on the windows build, which is now newly threaded by default; users of
SBCL on windows might wish to be as circumspect as they usually are when
dealing with new releases. Windows users might wish to note the plan to
drop support for unthreaded builds from the next release, and use this
release cycle to make sure that any potential problems are discovered in
advance of the next release.
Secondly, I meant to build the x86-64/Linux binary in a chroot but
forgot, meaning that the binary links to a relatively new libc version
rather than an older one; if this is a problem for anyone, a rebuild
starting from the x86-64/Linux binary for sbcl-1.1.0 should be
straightforward.
Best wishes,
Christophe
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)

</pre>Christophe Rhodes2012-11-02T14:45:56sbcl-1.1.0 released
http://comments.gmane.org/gmane.lisp.steel-bank.announce/136
<pre>Hi,
I've just released sbcl-1.1.0; the release notes are below. Don't get
too excited about the new version number; its main conceptual
significance is it's a new version number to indicate the new version
numbering system, which starts with "1.1" -- in other words, this is a
"monthly" release just like any other.
On the other hand, this is a .0 release in the sense that it's my first
for a while, and it's possible that something unnoticed has gone wrong.
Please let me know if there's something wrong with the release that
needs correcting.
Best wishes,
Christophe
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)

</pre>Christophe Rhodes2012-10-02T11:15:21SBCL 1.0.58 released
http://comments.gmane.org/gmane.lisp.steel-bank.announce/134
<pre>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). (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.
* 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.
</pre>Juho Snellman2012-08-06T22:16:27sbcl 1.0.57
http://comments.gmane.org/gmane.lisp.steel-bank.announce/133
<pre>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.)
** 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)

http://comments.gmane.org/gmane.lisp.steel-bank.announce/132
<pre>SBCL 1.0.56 has been released, with the following changes:
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)
</pre>Juho Snellman2012-04-13T02:02:02sbcl 1.0.55 released
http://comments.gmane.org/gmane.lisp.steel-bank.announce/131
<pre>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 which features to
build with. ** --arch option can be used to specify the
architecture to build for. (Mainly useful for building 32-bit
SBCL's on x86-64 hosts, not full-blows cross-compilation.) *
enhancement: extended package prefix syntax
<pkgname>::<form-in-package> which allows specifying name of the
default interning package for the whole form. * enhancement: when
*READ-EVAL* is true, arrays with element type other than T can be
printed readably using #.-based syntax. (Thanks to Robert Brown) *
enhancement: MAKE-ALIEN signals a storage-condition instead of
returning a null alien when malloc() fails. (lp#891268) *
enhancement: SB-EXT:PRINT-UNREADABLY restart for PRINT-NOT-READABLE
conditions can be conveniently accessed through function with the same
name, analogously to CONTINUE. * enhancement:
SB-EXT:*SUPPRESS-PRINT-ERRORS* can be used to suppress errors from
the printer by type, causing an error marker to be printed instead.
(Thanks to Attila Lendvai) * enhancement: BACKTRACE and DESCRIBE now
bind *PRINT-CIRCLE* to T, and generally behave better when errors
occur during printing. * enhancement: the test runner now takes a
--report-skipped-tests argument to report the individual tests
skipped as well as the number of skipped tests. * enhancement:
undefined functions now appear in backtraces as ("undefined
function") instead of ("bogus stack frame") on x86oids. *
enhancement: detected deadlocks no longer cause stderr to be spammed,
and deadlock errors are reported in an easier-to-decipher manner.
* enhancement: DESCRIBE on type designators reports the expansion in
more cases. * 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) * 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. * 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 account
for signed zeros. * bug fix: compiler error when typechecking a call
to a function with non-constant keyword arguments. * bug fix:
misoptimization of TRUNCATE causing erratic behaviour. * bug fix:
condition slot accessors no longer cause undefined function
style-warnings when used in the :REPORT clause of the DEFINE-CONDITION
form that defines them. (lp#896379) * bug fix: DEFGENERIC warns
about unsupported declarations, as specified by ANSI. (lp#894202)
* bug fix: SUBTYPEP tests involving forward-referenced classes no
longer bogusly report NIL, T. * bug fix: bogus style-warnings for
DEFMETHOD forms that both declared some required arguments ignored
and performed assignments to others. (lp#898331) * bug fix:
*EVALUATOR-MODE* :COMPILE treated (LET () ...) identically to
(LOCALLY ...) leading to internally inconsistent toplevel-formness. *
bug fix: non-toplevel DEFSTRUCT signaled a style warning for unknown
type. * bug fix: redefining a function whose previous definition
contained an unknown type no longer causes a style-warning.
(lp#806243) * bug fix: undefined functions now appear in backtraces
as ("undefined function") instead of ("bogus stack frame") on
non-x86oids. * bug fix: backtraces are no longer cut off at
("undefined function") when called under certain circumstances
(involving a caller-allocated stack frame) on PPC. * bug fix:
RUN-PROGRAM leaked a file-descriptor per call on non-Windows
systems. (regression since 1.0.53) * bug fix: GC deadlocks from
dladdr() on certain platforms. * bug fix: broken standard streams no
longer automatically cause recursive errors on debugger entry. *
bug fix: build ignored --dynamic-space-size=<size> argument to make.sh
(regression since 1.0.53) * bug fix: attempts to stack allocate a
required argument to a function with an external entry point caused
compiler-errors. * bug fix: compiler notes for failed stack
allocation for a function argument no longer claim to be unable to
stack allocate the function. * bug fix: COERCE now signals a
type-error on several coercions to 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.

</pre>Juho Snellman2012-01-09T04:16:02sbcl 1.0.54
http://comments.gmane.org/gmane.lisp.steel-bank.announce/130
<pre>SBCL 1.0.54 has been released with the following changes:
changes in sbcl-1.0.54 relative to sbcl-1.0.53:
* minor incompatible changes:
** RENAME-FILE on a symbolic links used to rename the linked-to file
instead of the link.
** DELETE-DIRECTORY on symbolic link to a directory used to delete the
directory, but now signal an error instead. Use TRUENAME to resolve the
pathname if you wish to delete the linked directory, and DELETE-FILE if
you wish to delete the
** The internal SB-THREAD::SPINLOCK API has been deprecated, and using
symbols associated with it will trigger a compile-time warning.
* thread-related enhancements:
(This work has been funded by the SBCL Threading 2011 IndieGoGo campaign.
Many thanks to generous donors!)
** Threading is now more reliable on non-Linux platforms. We still don't
consider threads on non-Linux platforms good enough to enable them by
default, but they're in a clearly better shape now.
** Deadlines supported now on all platforms.
** All blocking functions in the threading API now have a :TIMEOUT
argument.
** Semaphore notification objects have been added to SB-THREAD.
** SB-CONCURRENCY contrib now includes Allegro-style GATE objects.
** SB-EXT:COMPARE-AND-SWAP has been extended to support SLOT-VALUE,
STANDARD-INSTANCE-ACCESS, and FUNCALLABLE-STANDARD-INSTANCE-ACCESS.
** Users can now defined new places usable with SB-EXT:COMPARE-AND-SWAP
using an API anologous to defining new SETFable places.
* GC-related enhancements and bug fixes:
** --dynamic-space-size and --control-stack-size now understand Kb, Mb,
and Gb suffixes. Default is megabytes as before.
** on GENCGC targets, the default dynamic space size is now 512Mb for
32-bit systems, and 1Gb for 64-bit systems. (OpenBSD/x86-64 is the only
exception, defaulting to mere 444Mb to fit under default ulimits.) The
new defaults are in place to prevent hitting swap on low-end systems.
Use build-time option --dynamic-space-size to build an SBCL with
another default, or the runtime option to adjust the size at startup: a
good size is at most equal to the amount of physical memory the system
has.
** on GENCGC targets, nursery and generation sizes now default to 5% of
dynamic-space size.
** on GENCGC targets, SB-KERNEL:MAKE-LISP-OBJ no longer categorically
refuses to create SIMPLE-FUN objects.
** on 64-bit GENCGC targets, setting the nursery size above 4Gb now works.
(lp#870868)
** on CHENEYGC targets, SB-KERNEL:MAKE-LISP-OBJ now does the same
validation of pointer objects as GENCGC does, instead of a
comparatively weak bounds-check against the heap spaces.
* SB-BSD-SOCKETS bug fixes:
** GET-PROTOCOL-BY-NAME had a significant memory leak.
** GET-HOST-BY-NAME and GET-HOST-BY-ADDRESS small amounts of memory on
systems with getaddrinfo().
** GET-HOST-BY-NAME and GET-HOST-BY-ADDRESS weren't thread or interrupt
safe outside systems with getaddrinfo().
* enhancement: ASDF has been updated 2.019.
* enhancement: special-case TCO prevention for functions which never return
extended to untrusted types, keeping one more frame's worth of debug
information around in many cases.
* enhancement: debug-names of anonymous and local function are more
descriptive. Affects backtraces and SB-SPROF results. (lp#805100)
* enhancement: on win32, ABS of complex floats guards better against
overflows. (lp#888410)
* enhancement: RUN-PROGRAM now distinguishes exec() failing from child
process exiting with code 1. (lp#676987)
* enhancement: convenience function SET-SBCL-SOURCE-LOCATION for informing
the system where on the filesystem the SBCL sources themselves are
located. (Thanks to Zach Beane)
* enhancement: the compiler is now able to derive tighter bounds for
floating point numbers in some cases. (Thanks to Lutz Euler, lp#894498)
* bug fix: on 64-bit targets, atomic-incf/aref does index computation
correctly, even on wide-fixnum builds. (lp#887220)
* bug fix: (DIRECTORY "foo/*/*.*") did not follow symlinks in foo/ that
resolved to directories.
* bug fix: type mismatch when assigning to lexical variables no longer
result in fasl-dumping internal type objects. (lp#890750)
* bug fix: type mismatch on (SETF AREF) and function return values no
longer result in fasl-dumping internal type objects.
* bug fix: With several combinations of argument types, for example (EXPT
<integer> <(complex double)>), EXPT now uses double-precision throughout
instead of partially calculating only to single-precision. (lp#741564;
thanks to Lutz Euler)
* bug fix: SYMBOL-VALUE-IN-THREAD is no longer able to construct bogus
objects when interrupted by GC on PPC.

http://comments.gmane.org/gmane.lisp.steel-bank.announce/128
<pre>changes in sbcl-1.0.53 relative to sbcl-1.0.52:
* enhancement: on 64-bit targets, in src/compiler/generic/early-vm.lisp,
the parameter n-fixnum-tag-bits may now vary from 1 (fixnum =
(signed-byte 63)) to 3 (fixnum = (signed-byte 61)) at build-time.
* enhancement: SB-EXT:WAIT-FOR allows waiting for arbitrary events.
* minor(?) incompatible(?) change: The default fixnum width on 64-bit
targets is now 63 bits (up from 61).
* enhancement: DESCRIBE now reports a lambda-list and source location
for complext setf-expanders.
* bug fix: PUSH, PUSHNEW, POP, REMF, INCF, DECF, DEFINE-MODIFY-MACRO,
GETF, LOGBITP, LDB, and MASK-FIELD now arrange for non-primary values
of multiple-valued places to be set to NIL, instead of signalling an
error (per a careful reading of CLHS 5.1.2.3).
* bug fix: floating-point traps now work on darwin/x86 and /x86-64.
* bug fix: repair crash in x86oid darwin signal handling emulation
when built with certain compilers.
* bug fix: SB-ROTATE-BYTE misrotated to the right when using constant
rotation arguments on x86-64. (lp#882151)
* bug fix: low-level control flow optimisations could result in bogus
code in functions with tail and non-tail calls to local functions on
x86oids. (lp#883500)
* bug fix: on SPARC/:sb-unicode, avoid crashing the assembler by trying
to emit literal characters > (code-char 4095), for comparisons with
constant characters.
* bug fix: ROOM reported only the low 32 bits of dynamic space usage
on 64 bit platforms. (lp#881445)
* bug fix: DELETE-FILE did not MERGE-PATHNAMES, making it possible to
delete the wrong file when using relative pathnames. (lp#882877)
* bug fix: optimized SEARCH of vectors-on-vectors mishandled zero-length
sequences and :KEY NIL.
</pre>Juho Snellman2011-11-06T22:33:57sbcl 1.0.52 released
http://comments.gmane.org/gmane.lisp.steel-bank.announce/127
<pre>changes in sbcl-1.0.52 relative to sbcl-1.0.51: * enhancement: ASDF has been
updated to version 2.017. * enhancement: the --core command line option now
accepts binaries with an embedded core. * enhancement: when built with
:sb-core-compression, core files (regular or executable) can be compressed
with zlib. Use the :COMPRESSION argument to SAVE-LISP-AND-DIE to specify a
compression level. * enhancement: --[no-]merge-core-pages determines whether
the runtime hints the operating system that identical core pages between
SBCL processes should share the same physical memory. Default is to only
enable this for compressed cores. * optimization: SLEEP no longer conses. *
optimization: *PRINT-PRETTY* no longer slows down printing of strings or
bit-vectors when using the standard pretty-print dispatch table. * bug fix:
non-function FTYPE declarations no longer cause a compiler-error.
(lp#738464) * bug fix: compiler-errors causes by MEMBER types in conjunction
with with AREF, CHAR, etc. (lp#826971) * bug fix: compiler-errors causes by
integer arguments with composed of multiple ranges to ARRAY-IN-BOUNDS-P.
(lp#826970) * bug fix: ,< at > and ,. now signal a read-time error for certain
non-list expressions. (lp#770184) * bug fix: complex single float literals
are correctly aligned when used as arguments of arithmetic operators. * bug
fix: on 32-bit platforms, rounding of double floats larger than a fixnum is
correct. (reported by Peter Keller) * bug fix: stray FD-HANDLERs are no
longer left lying around after unwinds from RUN-PROGRAM. (lp#840190,
reported by Dominic Pearson; fix from Max Mikhanosha) * bug fix: redefining
classes such that slots with custom allocation are added or removed works
again.

http://comments.gmane.org/gmane.lisp.steel-bank.announce/126
<pre>SBCL 1.0.51 has been released, with the following changes:
changes in sbcl-1.0.51 relative to sbcl-1.0.50:
* minor incompatible change: SB-BSD-SOCKET socket streams no longer
participate in SERVE-EVENT by default: pass :SERVE-EVENTS T to
MAKE-SOCKET-STREAM if using SERVE-EVENT.
* enhancement: added support for socket keepalive timeout intervals
and probe counts on Linux.
* enhancement: building 32-bit SBCL on Linux/x86-64 now works without a
chroot. (Use "SBCL_ARCH=x86 sh make.sh" to build.)
* enhancement: added new toplevel options --quit and --non-interactive
(lp#822712).
* enhancement: the Windows port of SBCL now builds and runs on Wine
(thanks to Anton Kovalenko).
* enhancement: more, and more correct, SSE instruction definitions on
x86-64 (thanks to Alexander Gavrilov).
* enhancement: SB-EXT:SPIN-LOOP-HINT assembles to an instruction designed
to help the processor execute spin loops, when applicable. Currently
implemented for x86 and x86-64.
* optimization: unsigned integer divisions by a constant are implemented
using multiplication (affects CEILING, FLOOR, TRUNCATE, MOD, and REM.)
* optimization: improved type-derivation for LOAD-TIME-VALUE.
* bug fix: correct RIP offset calculation in SSE comparison and shuffle
instructions. (lp#814688)
* bug fix: COERCE to unfinalized extended sequence classes now works.
(reported by Jan Moringen; lp#815155)
* bug fix: a compiler error during typecheck generation, reported by Eric
Marsden. (lp#816564)
* bug fix: obsolete instance protocol fires when shared slots are added
or removed.
* bug fix: fixed-format floating point printing with scaling factors.
(lp#811386)
* bug fix: using GCC >= 4.6 to build SBCL on x86 no longer breaks
backtraces. (lp#818460)
* bug fix: better backtraces for interrupted syscall frames on x86.
(lp#549673)
* bug fix: SSE comparison instructions can be disassembled even when one
operand is in memory. (lp#814702)
* bug fix: incomplete writes when not using SERVE-EVENTS. (lp#820599)
* bug fix: MULTIPLE-VALUE-BIND + VALUES -> LET conversion could lose
derived
type information associated with the VALUES form.
* bug fix: broken warnings/errors for type-errors involving
LOAD-TIME-VALUE
forms. (lp#823014)
* bug fix: OPEN :IF-EXISTS :APPEND now returns correct FILE-POSITION
before
first write (lp#561642).
* bug fix: compiled closures from EVAL could not be DESCRIBEd. (lp#824974)
* bug fix: bound propagation involving conversion of large bignums to
floats no longer signals a SIMPLE-TYPE-ERROR, reported by Lutz Euler.
(lp#819269)
* bug fix: &REST to &MORE conversion still works in unsafe call to known
functions; reported by Lutz Euler (lp#826459).
* bug fix: bogus deadlocks from interrupts and GCs. (lp#807475, regression
since 1.0.48)
</pre>Juho Snellman2011-08-21T00:28:37sbcl 1.0.50
http://comments.gmane.org/gmane.lisp.steel-bank.announce/125
<pre>SBCL 1.0.50 has been released (git tag sbcl-1.0.50), source and Linux binary
tarballs available.
changes in sbcl-1.0.50 relative to sbcl-1.0.49:
* enhancement: errors from FD handlers now provide a restart to remove
the offending handler.
* enhancement: SB-INTROSPECT:FIND-DEFINITION-SOURCE now works on structure
copiers as well.
* enhancement: location of user or system initialization file can now
easily
be customized for saved cores. See: SB-EXT:*USERINIT-PATHNAME-FUNCTION*
and SB-EXT:*SYSINIT-PATHNAME-FUNCTION*.
* enhancement: SB-EXT:MAKE-THREAD accepts an argument list designator for
the thunk, as a keyword argument, :arguments.
* enhancement: constraint propagation is simplified (and sped up) when
COMPILATION-SPEED > SPEED.
* enhancement: SB-ALIEN exports alien type specifiers SIZE-T and OFF-T.
* enhancement: debugger understands &MORE arguments better.
* optimization: extracting bits of a single-float on x86-64 has been
optimized. (lp#555201)
* optimization: MAP and MAP-INTO are more efficient for non-simple
vectors,
when (> SPEED SPACE).
* optimization: local call trampolines (x86 and x86-64) are emitted
inline.
* optimization: implicit value cells for dynamic-extent closed-over
bindings
on x86 and x86-64 can hold unboxed values as well.
* meta-optimization: improved compilation speed, especially for large
functions. (lp#792363 and lp#394206)
* bug fix: bound derivation for floating point operations is now more
careful about rounding possibly closing open bounds. (lp#793771)
* bug fix: SB-POSIX:SYSCALL-ERROR's argument is now optional. (accidental
backwards incompatible change in 1.0.48.27)
* bug fix: occasional debugger errors in when a type-error occured in a
function with dynamic-extent &rest list.
* bug fix: &optional and &key supplied-p arguments in DEFSTRUCT
boa-construtors can be used to initialized structure slots.
* bug fix: FMAKUNBOUND removes the MACRO-FUNCTION, should one exist.
(lp#795705, regression)
* bug fix: DIRECTORY works better on logical pathnames.
* bug fix: RUN-PROGRAM no longer fails spuriously when argument strings
are of the order of ARRAY-TOTAL-SIZE-LIMIT. (lp#787237)
* bug fix: the compiler no longer constant-folds NaNs in
MAKE-{SINGLE,DOUBLE}-FLOAT. (lp#486812)
* bug fix: FORMAT now handles floating point rounding correct, eg.
(format nil "~,1F" 0.01) => "0.0" instead of "0.01" as previously.
(lp#308961)
* bug fix: style warning during lambda-list introspection of generic
functions with both optional and key argments.
* bug fix: regalloc doesn't barf on unused TNs due to type-directed
constant
folding. (lp#729765)
* bug fix: Fixed an off-by-one in MAP-ALLOCATED-OBJECTS that might have
caused
infinite loops.
