6baceca1 · ·changes in sbcl-1.2.7 relative to sbcl-1.2.6: * optimization: returning constant values refers to preboxed constants more reliably. (lp#1398785) * enhancement: a STYLE-WARNING is produced if a compiler-macro is defined for a function after at least one ordinary (not inlined) call to that function was compiled, indicating a likely compilation order problem. Likewise a warning ensues if a call is compiled to a function that is subsequently proclaimed INLINE. * enhancement: always lose() when something goes wrong while saving a core (instead of just printing an error on stderr in some situations). * enhancement: frames in the debugger are now restartable by default. * bug fix: restore error handling on Windows x86. * bug fix: MAKE-SEQUENCE detects type errors in its :INITIAL-ELEMENT at compile-time when possible. (lp#330299) * bug fix: parsing of malformed type specifiers no longer results in a memory-fault-error. * bug fix: LOOP properly destructures nested lists in WITH. * bug fix: MACROEXPANDing the redefinition of an alien structure type no longer signals the wrong error. * bug fix: PROGV doesn't get confused by forced DEBUG 3 (lp#1405456). -

e569d733 · ·changes in sbcl-1.2.6 relative to sbcl-1.2.5: * enhancement: SERVE-EVENTS uses the poll() system call in lieu of select() if the OS has the former. Previously poll() was used only if waiting on exactly one file descriptor. * enhancement: efficiency of access to untagged structure slots is improved on x86-64, and the order of slots in memory is exactly as specified by defstruct, simplifying use of structures as arguments to foreign calls. * bug fix: SB-DEBUG:ARG now works in all TRACE options which evaluate forms. (lp#1357826) * bug fix: GC memory corruption during internal memory handling. * bug fix: duplicate effective-slot-definition objects as compared by EQ on name could be present in CLASS-SLOTS of a class whose metaclass was structure-class or condition-class.

This behavior can be disabled with SB-EXT:READTABLE-NORMALIZATION * enhancement: a style-warning is signaled if OPTIMIZE declarations multiply specify a quality with differing values. (lp#310267) * bug fix: conservatively pointed to pages wipe out unused dwords so that they cannot act as false roots in turn. * bug fix: the walker's handling of lexical variable and symbol-macro bindings is improved (lp#375326, lp#1368305) * bug fix: HANDLER-{BIND,CASE} no longer drop into ldb when a clause contains an undefined condition type; regression in 1.1.19 (lp#1378939) * bug fix: in interpreted code, inequality predicates did not type-check arguments that weren't examined, and a 1-argument use of MIN or MAX accepted a complex number. (lp#1373702) * bug fix: APROPOS and APROPOS-LIST handle inherited symbols correctly. (lp#1364413, thanks to Zach Beane) -

(lp#721135) * bug fix: VALIDATE-SUPERCLASS returns T when the superclass is the universal superclass (lp#1332983) * bug fix: reading an uninterned symbol whose print name has the syntax of an integer signals an error.

sbcl-1.2.2
39d08435 · ·changes in sbcl-1.2.2 relative to sbcl-1.2.1: * incompatible change: the #\` ("backquote") reader macro was reimplemented to support robust pretty-printing. Reading a form involving #\` produces an invocation of the QUASIQUOTE ordinary macro which may contain subforms that are not lists. Code that unportably attempts operations on un-evaluated forms resulting therefrom, e.g. (SUBST a b (read-from-string "`(x (,y))")) might generate incorrect results and/or errors. * enhancement: support for GNU/kFreeBSD x86. * enhancement: ATOMIC-INCF and ATOMIC-DECF can operate on (CAR x), (CDR x) and DEFGLOBAL variables of type fixnum. * enhancement: arithmetic constant reduction is now performed on defconstant constants too. (lp#1337069). * bug fix: certain ftype proclamations containing &optional t &rest t no longer cause subsequent definitions to signal bogus style-warnings. * bug fix: #\Bell and #\Bel now read to different characters.

e4dd745e · ·changes in sbcl-1.1.15 relative to sbcl-1.1.14: * new feature: the iterative spilling/coloring register allocator developed by Alexandra Barchunova during Google Summer of Code 2013 is now merged in. By default, it only activates for functions that optimize with (speed 3) and (> speed compilation-speed), but setting sb-regalloc:*register-allocation-method* to :iterative forces its execution. The previous behaviour can be obtained by instead setting that variable to :greedy. Thanks again to Google for their support, and, more crucially, to Alexandra Barchunova for her hard work. * optimization: make-array with known element-type and unknown dimensions is much faster. * optimization: make-array with unknown element-type is faster as well.
