The GNU project and the GCC developers are pleased to announce the
release of GCC 4.4.3.
This release is a bug-fix release, containing fixes for regressions in
GCC 4.4.1 relative to previous releases of GCC.
ECL 10.3.1:
===========
This release has three important focuses: performance improvements in various
fronts (garbage collection and hash tables), extending the run-process function
and important fixes to let ECL work better with Slime. To quote one lisper
ECL "this feels like a real Lisp implementation now"
* Bugs fixed:
- DIRECTORY used stat() also on files that did not match the directory masks.
- The syntax for matching strings in DIRECTORY is now the same as in
PATHNAME-MATCH-P. Formerly there were small differences, such as DIRECTORY
understanding characters #\? and #\\ and PATHNAME-MATCH-P not.
- Standalone executables do not require the existence of the ECLDIR directory
to start up -- it may be required, though, for working Unicode because the
encodings are stored there.
- PROCESS-JOIN was exported from the wrong package.
- PROCESS-JOIN failed when invoked with a thread that was in the process of
being set up.
- The output values of a process or thread are now collected in the process
object and returned by PROCESS-JOIN.
- ECL's interrupt servicing thread could not be shut down.
- When compiling LET forms, ECL emitted warnings about removal of variables
even when they were declared IGNORABLE.
- An internal variable MP:*ALLOW-WITH-INTERRUPTS* was not declared special.
- The compiler now understands function type proclamations with &OPTIONAL
values.
- The compiler now accepts THE special forms with a VALUES type.
- If file A.lsp explicitely loads B.lsp to use a package that is only defined
in B, then ECL signaled an error in the compiled version of A even after
this one had required B.lsp.
- ECL accepts FTYPE proclamations for SETF-functions.
- On platforms where a stack overflow does not trigger a SIGSEGV, ECL was
unable to recover from the overflow. Now it jumps to the outermost
protection frame (typically the toplevel).
- Socket streams are now two-way streams. This solves a problem with certain
platforms (OS X) where a C stream can not be used to read and write
simultaneously by two different threads.
- TRUENAME and PROBE-FILE were not thread safe.
* Visible changes:
- Hash tables now use hand-coded specialized loops for EQ, EQL, EQUAL, EQUALP
and package types, achieving a reduction of about 30% time in lookups.
- A new function EXT:ENVIRON returns the list of strings that makes up the
process environment. This is the equivalent of POSIX (char **environ)
and Windows' GetEnvironmentStrings.
- EXT:RUN-PROGRAM now accepts a keyword argument, :ENVIRON, with a list of
strings used to configure the environment of the child process. For instance
'("PWD=/home" "PATH=/usr/bin")
- EXT:RUN-PROGRAM returns as third value an EXT:EXTERNAL-PROCESS structure,
which supports the queries EXT:EXTERNAL-PROCESS-{PID,INPUT,OUTPUT,STATUS},
following CCL's conventions.
- The new function EXT:EXTERNAL-PROCESS-WAIT can be used to wait indefinitely
for termination of a process or simply to query its status.
- ECL implements a new garbage collector marking mode which at the overhead of
one word per object achieves precise marking of heap objects, reducing
accidental data retention and improving the time spent in garbage
collection. This mode is only available when using --enable-boehm=system at
configuration time.
- ECL now ships with ASDF version 1.604
- The variables C:*USER-CC-FLAGS* and C:*USER-LD-FLAGS* are lists of strings
which can used to change the behavior of the C compiler and the
linker. Note, however, that the flags that ECL uses may take priority.
- In the C code we are beginning to use GCC's attributes (__attribute__) and
branch annotation (__builtin_expect). This decreases the size of code that
checks for errors and improves performance.
- When printing compiler notes, instead of printing the macroexpanded form,
ECL now prints the toplevel form, as follows
;;; Warning: in file src:lsp;autoload.lsp.NEWEST, position 1178 and top form
;;; (DEFMACRO WITH-COMPILATION-UNIT (OPTIONS &REST BODY) ...)
;;; The variable OPTIONS is not used.
- ECL now implements EXT:*INVOKE-DEBUGGER-HOOK*, which works like *DEBUGGER-HOOK*
but is also observed by BREAK. (SBCL extension adopted by ECL)
- The UFFI interface now supports C99 types, such as :int8-t, :uint32-t, etc,
but only when the corresponding types do exist in the underlying C environment.
- SOCKET-MAKE-STREAM defaults :BUFFERING to :FULL and allows three new keyword
arguments, :INPUT, :OUTPUT and :EXTERNAL-FORMAT, as in SBCL.
- COMPILE-FILE admits the keyword argument :EXTERNAL-FORMAT.
- A new function EXT:ALL-ENCODINGS lists all encondings known to ECL.
- Improved readability of compiler messages.
- SERVE-EVENT now allows time resolution of less than one second.
- The PROFILE package now has an alias, SB-PROFILE.
- ECL now stores the location of its source files in a logical hostname,
"SRC:", which points to the directory where Announcement is located.
- When building ECL, if "etags" is installed, a file TAGS is created which
contains references to the location of all C functions. This file can be
used to locate functions from the core library in Slime, using M-.
- Documentation files now allow for annotation of arbitrary symbols,
based on a key and a sub-key which are both symbols.
- New function EXT:FUNCTION-LAMBDA-LIST which currently only works with
functions from the core ECL library, generic functions and interpreted
functions.
- The debugger now is capable of showing the special variable bindings
from a function, as well as the restarts newly bound by that function.
- When using git, a new function EXT:LISP-IMPLEMENTATION-VCS-ID returns a
unique identifier denoting the last commit. This can be used to discriminate
between unstable releases and remove stale FASL files.
- COMPILE-FILE admits two new keyword arguments, :SOURCE-TRUENAME and
:SOURCE-OFFSET which can be used to change the value returned by
EXT:COMPILED-FUNCTION-FILE when acting on compiled functions.

New in Chicken 4.4.0:
- the system can now be built with llvm-gcc and/or "clang" (the
LLVM C compiler which doesn't use the GNU C frontend)
- added new option `-trunk' to `chicken-install', which forces
building and installing the development version of extensions
in combination with `-t local'
- added new option `-deploy' to `chicken-install', which builds
extension for use in "deployed" applications (see below)
- added option `-deploy' to `csc', the compiler driver. With this
option `csc' can build fully self-contained application bundles
and double-clickable Macintosh GUI apps; see the "Deployment"
manual chapter for more information
- the directory given to the `-prefix' option of `chicken-install'
may now be a relative pathname.
- removed GUI-specific runtime library (`libchicken-gui') from
Windows build - GUI- and non-GUI applications now use the same
runtime library
- special forms of the foreign-function interface have been replaced
with an internal form and syntax to allow renaming and shadowing of
these forms
- the new `-private-repository' option in `csc' compiles executables
with the extension-repository path set to the directory from which
the program was started
- `csc': deprecated the `-W' and `-windows' options, added `-gui' as
a platform-independent replacement
- `require-extension'/`use' accepts now import-specifications
- user-defined extension-specifiers and `set-extension-specifier!'
have been removed
- `delete-file[*]', `rename-file', `create-directory', `file-copy',
`file-move', `delete-directory' and `change-directory' return their
argument/destination filename on success
- added the missing procedure `condition-variable-name' to the
srfi-18 library unit (Thanks to Joerg Wittenberger)
- the `glob?' function from the `regex' unit has been deprecated
- added the procedure `scan-input-lines' to the `utils' library unit
- added new runtime option `-:g' which enables GC debugging output
- reclamation of unused symbols in "symbol-gc" mode (`-:w') now only
takes place for symbols with an empty property-list
- on Windows loading of code compiled with [non-]GUI runtime libraries
will fail and produce an error message when the loading executable
is linked with a different runtime system
- on Windows, GUI libraries were not correctly linked by `csc'
- unit posix: added setter for `file-modification-time'
- the banner shows the branchname of the build, unless it's "master"
- the `-no-install' option to `chicken-install' is ignored when
building/installing dependencies
- `chicken-uninstall' takes a glob instead of a regular expression as
argument
- the rename and compare functions for low-level macro-definitions
accept now arbitrary s-expressions and renames/compares them recursively
- `number->string' handles negative-numbers with bases different from 10
correctly (thanks to Peter Danenberg)
- removed deprecated `setup-install-flag' and `setup-verbose-flag' from
the `setup-api' module
- added new option `-repository' to `chicken-install' (Thanks to Christian
Kellermann)
- removed `chicken-setup' stub program
- fix to `csc' to use the correct library when fixing dynamic load paths
(Thanks to Derrell Piper)
- removed html documentation from distribution (the wiki manual will
now be installed)
- fixed bug in `reexport' which caused syntax not to be correctly
reexported
- previous assignments to a toplevel variable that are separated by
side effect free expressions are removed
- fixed windows version of `find-files' (thanks to Jim Ursetto)
- documentation for extensions is not installed automatically by
`chicken-install' anymore
- changed binary version from "4" to "5", because the new runtime
libraries are not binary-compatible with previous releases; this
means all eggs have to be reinstalled and existing programs be
recompiled!
- added unboxing pass to compiler which results in partially dramatical
performance improvements for unsafe floating-point-intensive code;
unboxing is enabled on optimization levels 4 and 5
- removed rest-argument-vector optimization as it could conflict
with inlining (thanks to Sven Hartrumpf)
- renamed `pointer-offset' to `pointer+' and deprecated `pointer-offset'
- toplevel assignments that have no other side-effects can be eliminated
if it can be shown that the value is not used (the compiler will
generate a warning in this case)
- removed deprecated `-quiet' option in `chicken' program
- removed deprecated `run-time-macros' declaration
- removed deprecated `-v2' and `-v3' options in `csc' program
- removed deprecated `list-of' function (it is exclusively available
as `list-of?' now)
- removed deprecated `stat-...' functions in posix library unit
- removed deprecated `for-each-line' and `for-each-argv-line' procedures
in utils library unit
- added `fpinteger?' and `fpabs'
- deprecated `define-compiled-syntax'
- added new floating-point primitives `fpsin', `fpcos', `fptan',
`fpasin', `fpacos', `fpatan', `fpatan2', `fpexp', `fplog',
`fpexpt' and `fpsqrt'
- heavy cleanup of floating math functions which gives much better performance,
especially for code compiled in unsafe mode
- calling `assert' with a single argument shows the tested expression
on failure
- various bugfixes and cleaning up
New in version 1.0.36
- new feature: SB-EXT:TYPEXPAND-1, SB-EXT:TYPEXPAND, and
SB-EXT:TYPEXPAND-ALL behave exactly like their MACROEXPAND
counterparts but work on type specifiers.
- new feature: SB-EXT:DEFINED-TYPE-NAME-P returns whether a
symbol is known to name a type specifier.
- new feature: SB-EXT:VALID-TYPE-SPECIFIER-P returns whether a
given type specifier is valid where "valid" basically means
"would be accepted as second argument of TYPEP".
- new feature: SB-INTROSPECT:FUNCTION-TYPE takes a
function-designator and returns the function's declared, or
derived FTYPE.
- new feature: SB-POSIX now supports accessing the d_ino
member of dirent structures. (Thanks to Philipp Marek and
Pierre THEIRRY)
- new feature: The function SB-EXT:SEED-RANDOM-STATE has been
added to provide for seeding a RANDOM-STATE object with
user-provided data or from the operating system's PRNG.
Also, (MAKE-RANDOM-STATE T) will attempt to initialize the
returned state from the operating system's PRNG where
possible. (Thanks to Fare Rideau; launchpad bug #310116)

- bug fix: A deadline handler was run without interrupts
enabled for a deadline signaled within
SB-THREAD:CONDITION-WAIT.
That could result in infinitely spinning, non-killable threads.
- bug fix: Backtrace from internal-errors on x86-64 os x was
truncated before reaching the erring stack frame.

News
changes in sbcl-1.0.35 relative to sbcl-1.0.34:
* optimization: ROUND with a single single-float or double-float argument
is properly inlined when possible.
* optimization: Slightly better code is generated for integer<->float
conversions and for single-float<->double-float conversions on x86-64.
* optimization: SB-ROTATE-BYTE:ROTATE-BYTE now generates more efficient
code for 32-bit and 64-bit rotations on x86-64.
* bug fix: The install script changes the ownership of directories as well
as files for contrib modules using asdf. (thanks to Eugene Ossintsev;
launchpad bug lp#508485)
* bug fix: TRUNCATE with a single single-float or double-float argument is
properly inlined when possible. (launchpad bug lp#489388)
* bug fix: Passing a rotation count of zero to SB-ROTATE-BYTE:ROTATE-BYTE
no longer causes a compiler error on x86 and ppc.
* bug fix: GET-MACRO-CHARACTER bogusly computed its second return value
always relative to *READTABLE* rather than the passed argument.
changes in sbcl-1.0.34 relative to sbcl-1.0.33:
* minor incompatible change: threading support is now enabled by default
on x86[-64] Linux.
* enhancement: SB-INTROSPECT:DEFTYPE-LAMBDA-LIST now also works on most
builtin types.
* enhancement: Errors during compile-time-too processing (i.e. EVAL-WHEN)
are now caught and reported just like errors during macroexpansion.
* enhancement: SB-POSIX now provides access to tcdrain(), tcflow(),
tcflush(), tcgetsid(), and tcsendbreak(). (thanks to Jerry James)
* enhancement: ASDF systems can now depends on SB-QUEUE.
* fixes and improvements related to Unicode and external formats:
** bug fix: error handling and restart usage in the ucs-2 external format
has been improved.
** there is now an implementation of the ucs-4 external format.
** the utf-16 and utf-32 external formats are supported.
* bug fix: SB-POSIX wrapper for putenv no longer tries to put lisp strings
in the environment. setenv() and unsetenv() are also provided. (reported by
Fare Rideau; launchpad bug lp#460455)
* bug fix: LOAD of both .fasl and .FASL type files now forces fasl-style
loading. This ensures sensible errors for .FASL files from other
implementations on case-insensitive filesystems. (reported by Willem
Broekema; launchpad bug lp#489417)
* bug fix: #p"\\\\" can now be read without error on Win32. (reported by
Willem Broekema; launchpad bug lp#489698).
* bug fix: some minor code rearrangements to reenable warning-free building
from CMUCL (reported by xme@gmx.net; launchpad bug lp#491104)
* bug fix: PRINT-OBJECT for clos instances respects the right margin when
pretty printing
* bug fix: FIND-PACKAGE & DEFPACKAGE were not thread safe. (reported by
Attila Lendvai)
changes in sbcl-1.0.33 relative to sbcl-1.0.32:
* new port: support added for x86-64 NetBSD. (thanks to Aymeric Vincent)
* improvement: support O_LARGEFILE access to files larger than 2GB on
x86-64/linux. (thanks to Daniel Janus; launchpad bug lp#453080)
* new feature: SB-INTROSPECT:WHO-SPECIALIZES-DIRECTLY to get a list of
definitions for methods specializing on the passed class itself.
* new feature: SB-INTROSPECT:WHO-SPECIALIZES-GENERALLY to get a list of
definitions for methods specializing on the passed class itself, or on
subclasses of it.
* new build flag: :sb-xref-for-internals; SBCL will collect xref information
about itself during the build (e.g. for M-? in Slime), if this flag is
enabled in customize-target-features.lisp. This will increase the core
size by about 5-6mb, though, so it's mostly interesting to SBCL
developers.
* new feature: various GENCGC tuning parameters have been experimentally
documented and exported from SB-EXT. See documentation for details.
* fixes and improvements related to Unicode and external formats:
** the Unicode character database has been upgraded to the
Unicode 5.2 standard, giving names and properties to a number of new
characters, and providing a few extra characters with case
transformations.
** improvement: restarts for providing replacement input/output on coding
errors for fd-stream external formats.
** improvement: where :<encoding> is a keyword corresponding to an
external format the system supports, it is now possible to specify
(:<encoding> :replacement <character>) as an external format which will
automatically substitute <character> on encoding or decoding errors for
streams and for STRING-TO-OCTETS and its inverse. (launchpad bug
lp#317072)
** improvement: the file streams underlying the standard streams (such as
*STANDARD-INPUT*, *TERMINAL-IO*) are opened with an external format
which uses the replacement mechanism to handle encoding errors,
preventing various infinite error chains and unrecoverable I/O
confusion.
** minor incompatible change: the utf-8 external format now correctly
refuses to encode Lisp characters in the surrogate range (char-codes
between #xd800 and #xdfff).
** fix a typo preventing conversion of strings into octet vectors
in the latin-2 encoding. (reported by Attila Lendvai; launchpad bug
lp#471689)
** fix a bug in the octet multibyte handling of decoding errors and the
USE-VALUE restart. (launchpad bug lp#314939)
** fix the bug underlying the expected failure in the FORCE-END-OF-FILE
restart on fd-stream decoding errors.
** fix a bug in the ATTEMPT-RESYNC fd-stream decoding restart when the
error is near the end of file.
** fix a double-error case in unibyte octet conversions, when the first
use of USE-VALUE is ignored.
** fix bugs in handling of undefined code points in unibyte encodings.
** fix LISTEN (and consequent hangs in READ-CHAR-NO-HANG) on bivalent
streams after an UNREAD-CHAR.
* enhancement: SB-INTROSPECT:ALLOCATION-INFORMATION also reports if the
object is allocated in a boxed region of dynamic space.
* enhancement: SB-POSIX:FORK now signals an error if an attempt to
fork with multiple Lisp threads running is made, instead of going
ahead with unpredictable consequences. (reported by Leslie Polzer)
* bug fix: uses of slot accessors on specialized method parameters within
the bodies of SLOT-VALUE-USING-CLASS methods no longer triggers a type
error while finalizing the class. This fix may cause classes with slot
accessors to be finalized later than previously. (reported by Lars Rune
Nøstdal; launchpad bug lp#473699)
* bug fix: restore buildability on the MIPS platform. (regression from
1.0.30.38, reported by Samium Gromoff)
* bug fix: inspecting closures is less likely to fail with a type error.
* bug fix: no timer starvation when setting the system clock back.
(launchpad bug lp#460283)
* bug fix: WITH-STANDARD-IO-SYNTAX now binds *PRINT-PPRINT-DISPATCH* to the
standard pprint dispatch table as specified by CLHS.
* bug fix: give CLISP a hint about a type declaration to enable it to build
the cross-compiler without warnings. (thanks to Josh Elasser; launchpad
bug lp#396597)
* bug fix: correctly dump literal objects in defaulting forms of arglists.
(reported by Attila Lendvai; launchpad bug lp#310132)
* bug fix: distinguish in type specifiers between arrays that might be
complex and arrays that are definitely complex. (launchpad bug lp#309129)
* bug fix: SUBTYPEP knows that the SYMBOL type is not SUBTYPEP the KEYWORD
type. (reported by Levente Mészáros; launchpad bug lp#485972)
* bug fix: setting the value of a symbol-macro within a method in the
presence of type declarations works properly again. (reported by Iban
Hatchondo; launchpad bug lp#485019)
changes in sbcl-1.0.32 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: DELETE-FILE once again works on logical pathnames (regression
since 1.0.30.49)
* bug fix: LOGICAL-PATHNAME signals a TYPE-ERROR if pathspec is specified
incorrectly.
* bug fix: redefinition of a class via DEFCLASS without :DEFAULT-INITARGS
removes previous default initargs (reported by Lars Rune Nøstdal and
Samium Gromoff)
* bug fix: correct WHO-CALLS information for inlined lambdas with complex
lambda-lists. (reported by Peter Seibel)
* 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)
* bug fix: Have RUN-PROGRAM with :INPUT T only run the subprocess in a
new process group if it doesn't need to share stdin with the sbcl
process. (thanks to Leslie Polzer)
* bug fix: SATISFIES could be misoptimized to refer to a local function.
(reported by Stanislaw Halik)
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

** 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
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: 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
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.
