Regression since 2e52fa05. + * LOGBITP and LOGTEST optimizations from x86 ported to x86_64. + +changes in sbcl-1.1.6 relative to sbcl-1.1.5: + * enhancement: the continuable error when defknown-ing over extant + fndb entries can be ignored by passing :overwrite-fndb-silently t + as a keyword argument to sb-c:defknown (after attributes). Useful + to allow defknown to be re-loaded. Use with :allow-other-keys t + for backward compatibility. + * optimization: compiler is much faster in compiling SVREF and (SETF SVREF) + forms. + * bug fix: Prevent a make-array transform from modifying source forms + causing problems for inlined code.

Works on Windows and on terminals with ANSI escape code + support. Can be disabled with --no-color. + * optimization: SB-CONCURRENCY:QUEUE implementation is more efficient. + (thanks to James M.

(Thanks to Anton Kovalenko.) + * enhancement: STDCALL alien callbacks. (Thanks to Anton Kovalenko.) + * enhancement: Safepoint builds on POSIX platforms can now optionally be + built without pseudo-atomic sequences and their run-time overhead. + * enhancement: Threads created outside of Lisp can enter Lisp through + alien callbacks and appear as Lisp threads for the duration of that + function invocation. On safepoint builds only. + * enhancement: Miscellaneous improvements to namestrings and underlying + calls to OS functions for file system access on Windows. (Thanks to + Anton Kovalenko.) + * enhancement: The MSI installer support for Windows now uses Windows + Installer XML at least version 3.5 and includes various usability + improvements.

Required on Windows. (Thanks to Anton + Kovalenko.) + * enhancement: Console I/O streams use UCS-2. (Thanks to Anton Kovalenko.) + * enhancement: I/O on Windows unnamed pipes is interruptible + asynchronously using interrupt-thread, timers when running on Windows NT + version 6.1 or newer (Windows 7, Server 2008 R2). (Thanks to Anton + Kovalenko.) + * enhancement: Support for the experimental safepoint-based stop-the-world + protocol on the PowerPC platform. + * bug fix: Non-blocking reads from the Windows console were not necessarily + non-blocking. Thanks to Anton Kovalenko. (lp#308923) + * bug fix: stability of threads on Windows has been improved upon through + an updated stop-the-world protocol (thanks to Anton Kovalenko). + +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.

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.
