sbcl-1.1.1
0baeb07f · ·changes in sbcl-1.1.1 relative to sbcl-1.1.0: * enhancement: WITH-COMPILATION-UNIT no longer grabs the world-lock. (COMPILE and COMPILE-FILE still do.) * optimization: the SPARC backend now supports the precise generational (GENCGC) garbage collection. Enabled by default on Solaris/SPARC and Linux/SPARC. Thanks to Raymond Toy (via CMUCL). * enhancement: add experimental support for the SB-THREAD feature and the timer facility on Windows. Thanks to Dmitry Kalyanov and Anton Kovalenko. Threads are enabled by default, and this version of SBCL is considered to be the last and final release to officially support building with threads disabled. * optimization: The compiler no longer rotates loops in some cases where this transformation actually lead to worse code being generated. * bug fix: SB-CLTL2:MACROEXPAND-ALL correctly handles shadowing of symbol-macros by lexical bindings. * bug fix: stack allocation was prevented by high DEBUG declaration in several cases. * bug fix: SB-EXT:GC-LOGFILE signaled an error when no logfile was set. (thanks to SANO Masatoshi) * bug fix: PARSE-NATIVE-NAMESTRING performed non-native parsing when :JUNK-ALLOWED was true. * bug fix: type derivation inferred overly conservative types for unions of array types.

Set (and :sb-thread :sb-safepoint :sb-thruption :sb-wtimer) to test these experimental features. Known remaining bugs include minor thread safety issues, less timely freeing of memory by GC, and certain (not yet optimally low) runtime overhead.

(Previously some values could be about 0.1 % more probable than others in the worst case.) ** RANDOM on large integer arguments is generally faster and conses less than before; this is visible for fixnums above a length of about 24 bits, but extremely so for bignums: the old implementation used time and space quadratical in the size of the argument there, the new one is linear. * enhancement: redesigned protocol for quitting SBCL.
