2e3a763d · ·changes in sbcl-0.9.11 relative to sbcl-0.9.10: * new platform: experimental support for SBCL x86/Darwin, including MacOS X 10.4.5 on Intel. * new feature: Unicode character names are now known to the system (through CHAR-NAME and NAME-CHAR). * new feature: the filesystem location of SBCL's core file is exposed to lisp through the variable SB-EXT:*CORE-PATHNAME*. * minor incompatible change: the contrib modules SB-POSIX and SB-BSD-SOCKETS no longer depend on stub C libraries; the intent of this change is to make it easier to distribute location-independent binaries. * bug fix: as implied by AMOP, standardized classes no longer have slots named by external symbols of public packages. (reported by Pascal Costanza) * optimization: calling functions via constant symbols -- as in (FUNCALL 'FOO) -- is now roughly as efficient as calling them via the function object as in (FUNCALL #'FOO). * optimization: on x86 and x86-64, the calling convention for the case of dealing with an unknown number of values has been altered to be friendlier to the prediction heuristics implemented, particularly with reference to CALL and RET pairing. (thanks to Alastair Bridgewater) * optimization: on x86, the code for access to thread-local symbol values and binding/unbinding of thread-local symbols is smaller. (thanks to Alastair Bridgewater) * enhancement: CONSTANTP is now able to determine constantness of more complex forms, including calls to constant-foldable standardized functions and some special forms beyond QUOTE. * fixed bug: occasional GC crashes on Solaris/x86 * optimization: x86-64 supports stack allocation of results of simple calls of MAKE-ARRAY, bound to variables, declared DYNAMIC-EXTENT * enchancement: the PROCESS-INPUT and -OUTPUT streams created by SB-EXT:RUN-PROGRAM can be used for both character and byte IO (thanks to James Knight) * fixed bug: CL:LISTEN always returns NIL at end of file, as required by the standard (thanks to Stephen Compall) -

98329126 · ·changes in sbcl-0.9.10 relative to sbcl-0.9.9: * new feature: new SAVE-LISP-AND-DIE keyword argument :EXECUTABLE can be used for bundling the runtime and the core file into one executable binary. This feature is not currently supported on all SBCL platforms. (thanks to James Bielman and NIIMI Satoshi) * new feature: a generational or ephemeral garbage collector is now the default on the PowerPC platform (both Linux and Darwin). The old Cheney (stop and copy) collector is a build-time option. (thanks to Cyrus Harmon, after Raymond Toy) * minor incompatible change: the method by which SBCL finds its contributed modules has changed; it no longer relies on symbolic links from an $SBCL_HOME/systems directory, but searches directly in the subdirectories of $SBCL_HOME. * enhancement: the dynamic heap size on the Linux/PPC platform is markedly larger, even using the older Cheney garbage collector. * fixed bug #399: full call to DATA-VECTOR-REF in accesses to certain complicated string types. (reported by Gary King) * fixed bug: STRING-TO-OCTETS and OCTETS-TO-STRING did not convert character codes. (thanks to Yaroslav Kavenchuk and Ivan Boldyrev) * fixed bug: DOCUMENTATION on structures no longer signals an error if no structure type of the right name exists. (reported by Glenn Ehrlich) * fixed bug: compiled calls to MAKE-INSTANCE where there is an applicable non-standard primary or :AROUND method on INITIALIZE-INSTANCE or SHARED-INITIALIZE and a non-keyword initarg no longer cause unbound variable errors. (reported by Kevin Reid) * fixed bug: metacircle resolution in cases where methods have slots added before the slots from STANDARD-METHOD. (reported by Jean Bresson) * fixed bug: the Power PC assembly code for calling into lisp sometimes computed its return address wrongly (depending on the 15th bit of the address, fixed at link time). This used to manifest itself in a segmentation violation while building PCL. (reported by Kevin Rosenberg, Eric Marsden, Lars Brinkhoff and many others over the years) * fixed bug: ROOM no longer reports silly numbers for stack usage if the stack pointer (treated as a signed integer) is negative. (thanks to Peter van Eynde) -

TOP and TOPLEVEL are now available as debugger commands for returning to the top level. * incompatible change: forms evaluated in the REPL now use the global optimization policy. * incompatible change: user- and system-initialization files are no longer processed with LOAD, but by READ and EVAL; hence the global optimization policy, startup package, readtable, etc, can be set by them. * The .fasl file format number has been incremented because of various incompatible changes. * internal entry point details and argument counts no longer appear in backtraces unless explicitly requested by setting SB-DEBUG:*SHOW-ENTRY-POINT-DETAILS*. * built-in and standard functions no longer have names like "top level local call to FOO". * fixed bug 32: functions defined in non-null lexical environments now have more legible printed representation * fixed bug 33: functions defined in non-null lexical environemnts are now more amenable to inspection by INSPECT. * workaround for bug 354: XEPs no longer appear in backtraces unless explicitly requested. * fixed bug: receiving the signal which results from attempting to write to mprotect()ed memory (SIGSEGV on Linux and some *BSDs, SIGBUS on other *BSDs) on architectures where the C stack is also the Lisp stack (x86 and x86-64) from foreign code no longer leads to debugger confusion or wild instability. (reported by Cheuksan Wang) * fixed bug: COUNT and EQUAL no longer issue compiler efficiency notes when operating on objects known to be SIMPLE-BIT-VECTORs. (reported by Lutz Euler) * fixed bug: (TYPEP X '(MEMBER ...)) no longer returns a list in compiled code. (reported by Paul Dietz) * fixed bug 276b: mutating with MULTIPLE-VALUE-SETQ a binding of a specialized parameter to a method to something that is not TYPEP the specializer is now possible. * fixed bug: the MAKE-INSTANCE optimization is now correct in the face of package deletion. * fixed bug: LOAD should bind *LOAD-PATHNAME* to the merged pathname. (reported by David Tolpin on c.l.l) * contrib improvement: the SB-SIMPLE-STREAMS contrib now defines STRING-SIMPLE-STREAM and FILE-SIMPLE-STREAM as subclasses of STRING-STREAM and FILE-STREAM, respectively. * contrib improvement: SB-INTROSPECT handles more of SLIME's needs than previously; in addition, its test suite is now run on build. (thanks to Luke Gorrie) * a more robust x86-64 disassembler. (thanks to Lutz Euler) * optimization: added a immediate representation for single-floats on x86-64 * fixed some bugs revealed by Paul Dietz' test suite: ** MISC.564: defined out-of-line version of %ATAN2 on x86. ** attempting to create a package with a colliding nickname causes correctable errors to be signalled. ** MISC.572-574: :START1 and :START2 broken for simple-base-strings. ** several x86-64 backend bugs related to sign-extension of immediate operands. -

862491df · ·changes in sbcl-0.8.20 (0.9alpha.0?) relative to sbcl-0.8.19: * fixed inspection of specialized arrays. (thanks to Simon Alexander) * fixed disassembly of SHLD and SHRD on x86. (thanks to David Lichteblau) * fixed loading of multiply forward-referenced layouts. (thanks to Cheuksan Wang) * fixed bug 7: less verbose COMPILE-FILE output. Additionally, the output is now directed to *STANDARD-OUTPUT* as specified by ANSI. (see COMPILE-FILE documentation for details of :PRINT option) * fixed bugs 19 and 317: fixed-format floating point printing is more accurate. This also fixes a bug reported by Adam Warner related to the ~@F format directive. * fixed bug 371: bignum print/read inconsistency. (thanks to Harald Hanche-Olsen) * fixed bug: SET-SYNTAX-FROM-CHAR correctly shallow-copies a dispatch table if the from-char is a dispatch macro character. * fixed bug: COUNT and EQUAL on bit vectors with lengths divisible by the wordsize no longer ignore the last word. (reported by Lutz Euler) * fixed bug in type checking of dynamic-extent variables. (reported by Svein Ove Aas) * optimization: sequence traversal functions use their freedom to coerce function designators to functions. * optimization: code with many calls to CLOS methods specialized on CLOS classes has had redundant type checks removed. * optimization: added declarations to speed up operations that access the internal character database (for example STRING-UPCASE) * optimization: comparison operations between floats and sufficiently small fixnums no longer create extra rationals * fixed some bugs related to Unicode integration: ** portions of multibyte characters at the end of buffers for character-based file input are correctly transferred to the start of the buffer at the next read. ** COMPILE-FILE now respects any EXTERNAL-FORMAT argument given, passing it through to OPEN. ** LOAD on source files likewise passes any EXTERNAL-FORMAT argument given to internal calls to OPEN. ** the built-in comment readers (introduced by character sequences ";" and "#|") are more forgiving to encoding errors; they will STYLE-WARN and then attempt to resync the stream at a character boundary. (thanks to Teemu Kalvas) * fixed some bugs in the x86-64 port: ** Negative short int return values from c-calls are sign-extended correctly. ** The stack is aligned to 16-bytes for c-calls, as required by the ABI. (thanks to Cheuksan Wang) ** The disassembler understands more x86-64. (thanks to Cheuksan Wang) ** The regression tests use SB-ALIEN:INT instead of SB-ALIEN:INTEGER for enums. (thanks to Vincent Arkesteijn) ** Multiple small optimizations and bugfixes for floating point operations. * fixed some bugs revealed by Paul Dietz' test suite: ** Space, Tab, Linefeed, Return and Page have the invalid secondary constituent character trait. ** SET-SYNTAX-FROM-CHAR correctly copies multiple-escape character syntax. ** WITH-INPUT-FROM-STRING should only update the index place on normal termination. ** Pretty-printing backquoted forms when *PRINT-CIRCLE* is true works more reliably. ** Bit-array operations (BIT-AND and similar) worked incorrectly with one-dimensional arrays with fill pointers. ** TYPE-OF failed on a complex with an integer realpart and a RATIO imagpart. ** compiler failure during type inference for the code of form (IF (EQL X (THE ...)) ...) (MISC.535). -

617d3450 · ·changes in sbcl-0.8.19 relative to sbcl-0.8.18: * new port: SBCL now works in native 64-bit mode on x86-64/Linux platform. The port supports 61-bit fixnums, large memory spaces and reloading shared object files. * enhancement: saving cores with foreign code loaded is now supported on ppc/Darwin in addition to the previously supported platforms. * enhancement: the statistical profiler now walks deeper into the call stack for more meaningful call-graphs and accrued time reports (x86/x86-64 only). It also now reports time spent in foreign functions. * enhancement: it is now possible to trace most individual methods of a generic function in addition to tracing the generic function itself. * bug fix: invalid :DEFAULT-INITARGS are detected in compiled calls to MAKE-INSTANCE. * bug fix: defaulted initargs are passed to INITIALIZE-INSTANCE and SHARED-INITIALIZE methods from compiled calls to MAKE-INSTANCE. * bug fix: COERCE to (COMPLEX FLOAT) of a complex number no longer produces an error. (thanks to Vincent Arkesteijn) * bug fix: NAMESTRING on pathnames with :WILD components in their directories works correctly. (thanks to Artem V. Andreev) * fixed bug 125: compiler preserves identity of closures. (reported by Gabe Garza) * bug fixed: functions with &REST arguments sometimes failed with "Undefined function" when compiled with (DEBUG 3). (reported by Robert J. Macomber) * bug fix: overflow during compiling of setting element of a bit vector with constant index and value. (reported by Timmy Douglas) * build fix: fixed the dependence on *LOAD-PATHNAME* and *COMPILE-FILE-PATHNAME* being absolute pathnames. * on x86 compiler partially supports stack allocation of dynamic-extent closures. * GO and RETURN-FROM do not check the extent of their exit points when compiled with SAFETY 0. * fixed some bugs related to Unicode integration: ** encoding and decoding errors are now much more robustly handled; it should now be possible to recover even from invalid input or output to the terminal. (thanks to Teemu Kalvas) ** provided a first cut at implementing STRING-TO-OCTETS and OCTETS-TO-STRING. (thanks to Robert J. Macomber) ** altered the SB-MD5 contributed module slightly, changing the interface just enough for it to be supportable for builds where lisp characters are not eight bits. * fixed some bugs revealed by Paul Dietz' test suite: ** the FORMATTER-generated functions for ~V[ conditionals require the correct number of arguments. ** READ-FROM-STRING returns the mandated second value when applied to displaced strings. ** the #\Rubout and #\Backspace characters are treated as invalid constituent characters by the tokenizer. -

(thanks to Vincent Arkesteijn) * fixed bug #331: structure-class instances corresponding to DEFSTRUCT forms are now created eagerly. * fixed bug #345: backtraces from calls to undefined functions work on x86 as well. Related bug #61 is now also partially fixed on x86 (backtraces from throws to unknown catch tags.) * bug fix: lambda-list parsing is now stricter vrt. order and number of lambda-list keywords. * bug fix: as specified by AMOP, an error is signalled if a class-option appears multiple times in a DEFCLASS form. (reported by Bruno Haible) * bug fix: RANDOM can be compiled when the compiler derives the type of its numeric argument as a disjoint set of small integers. (reported by Paul Dietz) * bug fix: starting a core saved with shared objects loaded when those objects are not available no longer causes threaded SBCL to hang. (reported by Sean Ross) * bug fix: evaluated FUNCTION no longer bypasses encapsulation (eg. TRACE). * bug fix: (SETF MACRO-FUNCTION) now accepts an optional environment argument, which must always be NIL.
