+ * new feature: SB-EXT:DEFGLOBAL macro allows defining global non-special
+ variables.
+ * new feature: SB-EXT:ALWAYS-BOUND proclamation inhibits MAKUNBOUND, and
+ allows the compiler to safely elide boundedness checks for special
+ variables.
+ * new feature: SB-EXT:GLOBAL proclamation inhibits SPECIAL proclamations for
+ the symbol, prohibits both lexical and dynamic binding. This is mainly an
+ efficiency measure for threaded platforms, but also valueable in
+ expressing intent.
+ * improvement: SBCL now emits a compiler note where stack allocation was
+ requested but could not be provided.
* optimization: compiler now generates faster array typechecking code.
* optimization: ARRAY-DIMENSION is now faster for multidimensional and
non-simple arrays.
* optimization: multidimensional array accesses in the absence of type
information regarding array rank are approximately 10% faster due to
open coding of ARRAY-RANK.
+ * documentation: CLOS slot typechecing policy has been documented.
* bug fix: potential miscompilation of array stack allocation on x86 and
x86-64. (reported by Time Tossavainen)
* bug fix: some forms of AND, OR, and COND resulted in expansions that could
* bug fix: special variables with a proclaimed specific subtype of FUNCTION
could not be assigned to or bound with PROGV. (reported by Lorenz
Mösenlechner)
+ * bug fix: the value of CL:- in the inspector was the previous expression
+ evaluated rather than the expression being evaluated.
+ * bug fix: constants can no longer be locally declared special.
+ * bug fix: signals delivered to threads started from foreign land (read:
+ directly by pthread_create, not by MAKE-THREAD) are redirected to a Lisp
+ thread by blocking all signals and resignalling.
changes in sbcl-1.0.28 relative to 1.0.27:
* a number of bugs in cross-compilation have been fixed, with the ultimate
