(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) + * fixed some bugs revealed by Paul Dietz' test suite: + ** MISC.564: defined out-of-line version of %ATAN2 on x86. + +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). + 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
