(Earlier LIST and LIST* supported stack-allocation, but + CONS did not.) + * enhancement: nested lists can now be stack allocated on + platforms providing stack allocation support. + * enhancement: dynamic-extent support has been extended to support + cases where there are multiple possible sources for the stack + allocated value. + * bug fix: symbol-macro expansion now uses the *MACROEXPAND-HOOK* + as specified by the CLHS. (thanks to Tobias Rittweiler) + +changes in sbcl-1.0.10 relative to sbcl-1.0.9: + * minor incompatible change: the MSI installer on Windows no longer + associates .lisp and .fasl files with the installed SBCL. + * minor incompatible change: :UNIX is no longer present in *FEATURES* + on Windows. (thanks to Luis Oliviera) + * new feature: SB-CLTL2 contrib module now implements + FUNCTION-INFORMATION. (thanks to Larry D'Anna) + * optimization: scavenging weak pointers is now more efficient, + requiring O(1) instead of O(N) per weak pointer to identify + scanvenged vs. unscavenged pointers. (thanks to Paul Khuong) + * optimization: typechecking (SETF SLOT-VALUE) is now ~5x faster in + method bodies using constant slot-names when the first argument is + a specializer parameter for the method. + * optimization: SLOT-VALUE &co are now ~50% faster for variable slot + names, when the class of the instance is a direct instance + STANDARD-CLASS or FUNCALLABLE-STANDARD-CLASS (making them only 3x + as slow as the constant slot-name case.) + * optimization: member type construction is now O(N) instead + of O(N^2). + * optimization: UNION and NUNION are now O(N+M) for large + inputs as long as the :TEST function is one of EQ, EQL, EQUAL, or + EQUALP. + * enhancement: DEFINE-MODIFY-MACRO lambda-list information is + now more readable in environments like Slime which display it. + (thanks to Tobias C. Rittweiler) + * bug fix: SB-EXT:COMPARE-AND-SWAP was non-atomic unless the compiler + was able to infer the correct argument type for the object on which + the CAS operation was being performed. + * bug fix: copy propagation interfered with parallel assignment + semantics in local calls. (reported by Paul Khuong) + * bug fix: the signed modular fixnum shift compiled to wrong code on + x86 and x86-64. (spotted by a slight modification to some of + PFD's random tests) + +changes in sbcl-1.0.9 relative to sbcl-1.0.8: + * minor incompatible change: SB-SYS:OUTPUT-RAW-BYTES is deprecated. + * enhancement: SB-EXT:FINALIZE accepts a :DONT-SAVE keyword argument, + indicating the finalizer should be cancelled when SAVE-LISP-AND-DIE + is called. + * enhancement: default PRINT-OBJECT methods for classes, slot-definitions, + and generic function now print the object identity for anonymous + instances. (thanks to Attila Lendvai) + * enhancement: as an extension to MOP, SBCL now supports SETF of + STANDARD-INSTANCE-ACCESS and FUNCALLABLE-STANDARD-INSTANCE-ACCESS. + (thanks to Attila Lendvai) + * enhancement: sb-cover has an alternate annotation mode which puts + the form annotations at the car of the form, instead of annotating + it completely. The benefit of this mode is that it shows better + which forms were instrumented by the compiler. + * bug fix: new compiler transforms for MEMBER and ASSOC were affected + by printer control variables. (reported by Dan Corkill) + * bug fix: system leaked memory when delayed output was performed by + the OS in smaller chunks then expected. (thanks to David Smith) + * bug fix: system leaked memory when file streams were not closed + properly. + * bug fix: large objects written to slow streams that were modified + after the write could end up with the modified state written to + the underlying file descriptor. + * bug fix: multiple threads operating in parallel on the same stream + could cause buffer-overflows. + * bug fix: source location information is stored correctly + (broken since 1.0.6). This bug would generally show up as the + Slime debugger higlighting the wrong form when the sldb-show-source + command was used. + * bug fix: Branch forms are again annotated as branches in the sb-cover + annotations. + * bug fix: GCD on MOST-NEGATIVE-FIXNUM no longer causes an infinite loop + on x86-64. (reported by Gregory Vanuxem) + * bug fix: EQUALP could return wrong results for structures with raw + slots (slots with a :TYPE of SINGLE-FLOAT, DOUBLE-FLOAT, or a machine + word). (reported by Vjacheslav Fyodorov) + * bug fix: sb-sprof sampling didn't work on non-x86oid platforms.
