(reported by Cedric St-Jean) + * bug fix: circularity handling in the reader did not treat raw + structure slots correctly. (reported by Cedric St-Jean) + +changes in sbcl-1.0.21 relative to 1.0.20: + * new feature: the compiler is able to track the effective type of a + generic function across method addition and removal. + * new feature: SB-EXT:ATOMIC-INCF allows atomic incrementation of + appropriately typed structure slots without locking. + * new feature: SB-EXT:CALL-WITH-TIMING provides access to timing + information like those gathered by TIME using a programming-friendly + interface. + * new feature: TIME reports time taken even if the form performs a + non-local transfer of control. + * enhancement: reduced conservativism on GENCGC platforms: on + average 45% less pages pinned (measured from SBCL self build). + * bug fix: SB-EXT:COMPARE-AND-SWAP on SYMBOL-VALUE can no longer + mutate constant symbols or violate declaimed type of the symbol. + * bug fix: SB-THREAD:SIGNAL-SEMAPHORE could fail to wakeup threads + sleeping on the semaphore in heavily contested semaphores. + * bug fix: semaphores and condition variables were not interrupt + safe. + * bug fix: SB-THREAD:CONDITION-WAIT doesn't allow waits on mutexes + owned by other threads anymore. + * bug fix: FIND on lists called KEY outside the specified + subsequence. (reported by budden) + * bug fix: LOG doesn't use single-float intermediate results when + given mixed integer and double-float arguments, leading to better + precision. (reported by Bob Felts) + * bug fix: LOG with base zero returned values of inconsistent type. + +changes in sbcl-1.0.20 relative to 1.0.19: + * minor incompatible change: OPTIMIZE qualities + SB-C::STACK-ALLOCATE-DYNAMIC-EXTENT, SB-C::STACK-ALLOCATE-VECTOR, + and SB-C::STACK-ALLOCATE-VALUE-CELLS no longer exist. 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.
