See documentation + and SB-EXT:*STACK-ALLOCATE-DYNAMIC-EXTENT* for details. + * documentation: some slot access efficiency guidelines have been + added to the user manual. + * optimization: ASSOC-IF, ASSOC-IF-NOT, MEMBER-IF, MEMBER-IF-NOT, + RASSOC, RASSOC-IF, and RASSOC-IF-NOT are now equally efficient + as ASSOC and MEMEBER. + * optimization: calls to ASSOC, MEMBER, and RASSOC can be transformed + to more efficient EQ-comparison versions more often. + * optimization: enhanced derivation of DOLIST iteration variable type + for constant lists. + * optimization: constant folding of simple (LIST ...) forms as DOLIST + arguments. + * optimization: runtime lookup of function definitions can be + elided in more cases, eg: (let ((x 'foo)) (funcall foo)). + * optimization: compiler is able to derive the return type of + (AREF (THE STRING X) Y) as being CHARACTER. + * optimization: CLRHASH on empty hash-tables no longer does pointless + work. (thanks to Alec Berryman) + * optimization: REPLACE deftransforms don't punt when :START1 or + :START2 is given + * bug fix: compiling DESTRUCTURING-BIND on constant list arguments + no longer emits a code deletion note. (reported by Andrew + Gasparovic) + * bug fix: bogus odd-number-of-keywords STYLE-WARNINGs from calls to + functions with an odd number of &OPTIONAL arguments, a &REST + argument, and one or more &KEY arguments at the call site. + * bug fix: STYLE-WARNINGs for functions with both &OPTIONAL and &KEY + arguments appeared at call sites as well. + * bug fix: fixed #425; CLOSE drops input buffers from streams, so + READ-LINE &co can no longer read from them afterwards. (reported + by Damien Cassou) * bug fix: fixed #427: unused local aliens no longer cause compiler breakage. (reported by Stelian Ionescu, Andy Hefner and Stanislaw Halik) + * bug fix: non-local exit from a WITH-ALIEN form no longer causes + alien-stack leakage. (reported by Andy Hefner) + * bug fix: PROGV signals an error when an attempt to violate declared + type of a variable or bind a constant is made. + * bug fix: SET signals an error when an attempt to violate declared + type of a variable is made. + * bug fix: restart computation during the execution of a restart + test function no longer causes infinite recursion.
