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. + (lp#1004501) + * enhancement: sb-ext:save-lisp-and-die on Windows now accepts + :application-type argument, which can be :console or :gui. :gui allows + having GUI applications without an automatically appearing console window. + * enhancement: reduced conservativism on GENCGC platforms: + conservative roots must be valid-looking tagged pointers or point + within a code object, not merely point to within the allocated part + of a page, in order to pin a page. + * enhancement: support for "Mac Roman" external format. + * enhancement: encapsulation of named generic functions now happens without + altering the identity of the function bound to the name. + * bug fix: Windows applications without the console window no longer misbehave. + (patch by Wilfredo Velazquez, lp#1256034). + * bug fix: modular arithmetic optimizations do not stumble on dead branches + with bad constants. (reported by Douglas Katzman) + * bug fix: CLISP can be used again as a cross-compilation host. + (Thanks to Vasily Postnicov, lp#1261451) + * bug fix: run-program crashed with :directory nil. (lp#1265077) + +changes in sbcl-1.1.14 relative to sbcl-1.1.13: + * optimization: complicated TYPEP tests are less opaque to the type + propagation pass. (lp#1229340) + * optimization: [N]BUTLAST perform a single pass over the list. (lp#1245697) + * optimization: EQUALP on structures with raw slots (double-float/complex) + no longer conses and is faster. + * optimization: RESTART-CASE expands to more compact code. + Thanks to Jan Moringen. (lp#1249055) + * enhancement: Top-level defmethod without defgeneric no longer causes + undefined-function warnings in subsequent forms. (lp#503095) + * enhancement: Better error messages for system errors on Windows. + * enhancement: run-sbcl.sh is usefully handled by rlwrap. Thanks to William + Cushing. (lp#1249183) + * enhancement: new function SB-EXT:ASSERT-VERSION->= accepts a version + specification (multiple integer arguments) and signals a continuable error + if the current SBCL version is lower (older) than the specification. + (lp#674372) + * enhancement: better ARRAY-RANK result derivation. (lp#1252108) + * bug fix: EQUALP now compares correctly structures with raw slots larger + than a single word. + * bug fix: contribs couldn't be built on Windows with MinGW. + * bug fix: Better pathname handling on Windows. (lp#922117) + * bug fix: OPEN reports a more meaningful error when an existing file is + opened for output with :if-exists :new-version. Thanks to Philip + Munksgaard. (lp#455381) + * bug fix: DEFSTRUCTs with NIL as a slot name no longer cause strange + CLOS-related errors. (lp#633911) + * bug fix: GC deadlocks caused by concurrent consing on Windows. + +changes in sbcl-1.1.13 relative to sbcl-1.1.12: + * optimization: better distribution of SXHASH over small conses of related + values. (lp#309443) + * other improvements to SXHASH: + ** use the whole of the positive-fixnum range for SXHASH of fixnums + * enhancement: The error message when calling an undefined alien function + includes the name of the function on x86-64. + * enhancement: sb-ext:run-program now supports :environment on Windows. + * enhancement: ASDF is no longer required to load contribs at runtime. + (lp#1132254) + * enhancement: when called with a symbol, FIND-RESTART no longer calls + COMPUTE-RESTARTS, making it faster and cons less (lp#769615) + * enhancement: FIND-RESTART and COMPUTE-RESTARTS handle huge restart + clusters better in some cases + * enhancement: SOME/ANY/other quantification higher-order functions no + longer cons. (lp#1070635) + * bug fix: forward references to classes in fasls can now be loaded. + (lp#746132) + * bug fix: don't warn on a interpreted->compiled function redefinition + from the same location. (patch by Douglas Katzman, lp#1042405) + * bug fix: Create vectors of proper internal length when reading literal + vectors from FASLs. (Reported by Jan Moringen) + * bug fix: COMPILE can now successfully compile setf functions. + (Reported by Douglas Katzman) + * bug fix: run-program performs more correct escaping of arguments on + Windows. (lp#1239242) + * bug fix: function-lambda-expression on generic functions returns the + actual name. + * bug fix: (the [type] [constant]) now warns when [constant] matches + [type] except for the number of values. (Reported by Nathan Trapuzzano + on sbcl-help) + * bug fix: signal errors in required cases of slot-definition initialization + protocol. (lp#309072) + * bug fix: run-sbcl.sh works better in the presence of symlinks on OS X. + (thanks to Stelian Ionescu, lp#1242643) + * bug fix: when given a restart object, FIND-RESTART checks whether the + restart is active and, when a condition is supplied, whether the restart + is associated to a different condition (lp#774410) + +changes in sbcl-1.1.12 relative to sbcl-1.1.11: + * enhancement: Add sb-bsd-sockets:socket-shutdown, for calling + shutdown(3). (thanks to Jan Moringen, lp#1207483) + * enhancement: document extensible sequences. (thanks to Jan Moringen, + lp#994528) + * optimization: EQUAL and EQUALP transforms are smarter. + (thanks to Elias Martenson, lp#1220084) + * optimization: CHAR-EQUAL is faster for constant and base-char arguments. * bug fix: probe-file now can access symlinks to pipes and sockets in /proc/pid/fd on Linux. (reported by Eric Schulte) * bug fix: SBCL can now be built on Solaris x86-64. - + * bug fix: Floating point exceptions do not persist on Solaris anymore. + * bug fix: (setf . a) is pprinted correctly (reported by Douglas Katzman). + * bug fix: handle compiler-error in LOAD when it's not run from inside EVAL. + (lp#1219601) + * bug fix: SB-GMP:MPZ-POW no longer segfaults given a non-bignum base. + (thanks to Stephan Frank) + * bug fix: space allocation of result bignums in SB-GMP is more accurate. + (thanks to Stephan Frank, lp#1206191) + * bug fix: sb-safepoint can now reliably handle signal interruptions of + foreign code.

(thanks to Anton Kovalenko, lp#884603) + * bug fix: class definitions with CPLs inconsistent with their metaclasses + are less likely to destroy the object system's integrity. (lp#309076) + * bug fix: restart clause parsing in RESTART-CASE is more in line with the + standard. (lp#1203585, thanks to Jan Moringen) + * bug fix: silence a note from RESTART-CASE under high-SPEED optimization + settings. (lp#1023721) + * bug fix: getting the order of arguments to + SB-MOP:SET-FUNCALLABLE-INSTANCE-FUNCTION wrong produces a sensible error + rather than a failed AVER. (reported by Paul Nathan) + * bug fix: Parsing of &optional/&key/&rest arguments now never overwrites + arguments during copying on x86 and x86-64; it may still happen on other + platforms when there are more fixed arguments than stack slots. + (reported by Jan Moringen) + changes in sbcl-1.1.11 relative to sbcl-1.1.10: * enhancement: support building the manual under texinfo version 5.
