(thanks to David + Lichteblau) + * 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) + * 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. + +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. + changes in sbcl-0.8.18 relative to sbcl-0.8.17: * new feature: reloading changed shared object files with LOAD-SHARED-OBJECT now causes the new definitions to take effect. @@ -7,6 +112,8 @@ changes in sbcl-0.8.18 relative to sbcl-0.8.17: available at runtime. * Solaris 10 (aka SunOS 5.10) on the SPARC platform is now supported.
