I apologize for this, because it was + listed in SB-EXT as a supported extension, but I found that + its existing behavior was poorly specified, as well as incorrectly + specified, and it looked like too much of a mess to straighten it + out. I have enough on my hands trying to get ANSI stuff to work.. +* many patches ported from CMU CL by Martin Atzmueller, with + half a dozen bug fixes in pretty-printing and the debugger, and + half a dozen others elsewhere +* fixed bug 13: Floating point infinities are now supported again. + They might still be a little bit flaky, but thanks to bug reports + from Nathan Froyd and CMU CL patches from Raymond Toy they're not + as flaky as they were. +* The --noprogrammer command line option is now supported. (Its + behavior is slightly different in detail from what the old man + page claimed it would do, but it's still appropriate under the + same circumstances that the man page talks about.) +* The :SB-PROPAGATE-FLOAT-TYPE and :SB-PROPAGATE-FUN-TYPE features + are now supported, and enabled by default. Thus, the compiler can + handle many floating point and complex operations much less + inefficiently. (Thus e.g. you can implement a complex FFT + without consing!) +* The compiler now detects type mismatches between DECLAIM FTYPE + and DEFUN better, and implements CHECK-TYPE more correctly, and + SBCL builds under CMU CL again despite its non-ANSI EVAL-WHEN, + thanks to patches from Martin Atzmueller. +* various fixes to make the cross-compiler more portable to ANSI-conforming-but-different cross-compilation hosts (notably Lispworks for Windows, following bug reports from Arthur Lemmens) -?? The :PROPAGATE-FLOAT-TYPE and :PROPAGATE-FUN-TYPE target features - are now enabled by default. Now the compiler can handle many - floating point and complex operations much less inefficiently. - (Thus e.g. you can implement a complex FFT without consing!) +* A bug in READ-SEQUENCE for CONCATENATED-STREAM, and a gross + ANSI noncompliance in DEFMACRO &KEY argument parsing, have been + fixed thanks to Pierre Mai's CMU CL patches. +* fixes to keep the system from overflowing internal counters when + it tries to use i/o buffers larger than 16M bytes +* fixed bug 45a: Various internal functions required to support + complex special functions have been merged from CMU CL sources. + (When I was first setting up SBCL, I misunderstood a compile-time + conditional #-OLD-SPECFUN, and so accidentally deleted them.) +* improved support for type intersection and union, fixing bug 12 + (e.g., now (SUBTYPEP 'KEYWORD 'SYMBOL)=>T,T) and some other + more obscure bugs as well +* some steps toward byte-compiling non-performance-critical + parts of the system, courtesy of patches from Martin Atzmueller +* Christophe Rhodes has made some debian packages of sbcl at + . + From his sbcl-devel e-mail of 2001-04-08 they're not completely + stable, but are nonetheless usable. When he's ready, I'd be happy + to add them to the SourceForge "File Releases" section. (And if + anyone wants to do RPMs or *BSD packages, they'd be welcome too.) +* new fasl file format version number (because of changes in + internal representation of (OR ..) types to accommodate the new + support for (AND ..) types, among other things) + +changes in sbcl-0.6.13 relative to sbcl-0.6.12: +* a port to the Alpha CPU, thanks to Dan Barlow +* Martin Atzmueller ported Tim Moore's marvellous CMU CL DISASSEMBLE + patch, so that DISASSEMBLE output is much nicer. +* better error handling in CLOS method combination, thanks to + Martin Atzmueller and Pierre Mai +* Hash tables can be printed readably, as inspired by CMU CL code + of Eric Marsden and SBCL code of Martin Atzmueller. +* a new slam.sh hack to shorten the edit/compile/debug cycle for + low-level changes to SBCL itself, and a new :SB-AFTER-XC-CORE + target feature to control the generation of the after-xc.core + file needed by slam.sh. +* Compiler trace output (the :TRACE-FILE option to COMPILE-FILE) + is now a supported extension again, since the consensus is that + it can be useful for ordinary development work, not just for + debugging SBCL itself. +?? more overflow fixes for >16Mbyte i/o buffers +* minor incompatible change: The ENTRY-POINTS &KEY argument to + COMPILE-FILE is no longer supported, so that now every function + gets an entry point, so that block compilation looks a little + more like the plain vanilla ANSI section 3.2.2.3 scheme. planned incompatible changes in 0.7.x: * The debugger prompt sequence now goes "5]", "5[2]", "5[3]", etc. as you get deeper into recursive calls to the debugger command loop, instead of the old "5]", "5]]", "5]]]" sequence. (I was motivated - to do this when ILISP and SBCL got into arguments which left me - deeply nested in the debugger.) -* When the profiling interface settles down, it might impact TRACE. - They both encapsulate functions, and it's not clear yet how - e.g. UNPROFILE will interact with TRACE and UNTRACE. (This shouldn't - matter, though, unless you are using profiling. If you never - profile anything, TRACE should continue to behave as before.) + to do this when squabbles between ILISP and SBCL left me + very deeply nested in the debugger.) +* The fasl file extension may change, perhaps to ".fasl". +* The default output representation for unprintable ASCII characters + which, unlike e.g. #\Newline, don't have names defined in the + ANSI Common Lisp standard, may change to their ASCII symbolic + names: #\Nul, #\Soh, #\Stx, etc. +* INTERNAL-TIME-UNITS-PER-SECOND might increase, e.g. to 1000. +* FASL file extensions change to ".fasl", instead of the various + CPU-dependent values (".x86f", ".axpf", etc.) inherited from CMU CL. +* MAYBE-INLINE will probably go away at some point, maybe 0.7.x, + maybe later, in favor of the ANSI-recommended idiom for making + a function optionally inline. +* When the profiling interface settles down, maybe in 0.7.x, maybe + later, it might impact TRACE. They both encapsulate functions, and + it's not clear yet how e.g. UNPROFILE will interact with TRACE + and UNTRACE. (This shouldn't matter, though, unless you are + using profiling. If you never profile anything, TRACE should + continue to behave as before.) +* The BYTE-COMPILE &KEY argument for COMPILE-FILE is deprecated, + since this behavior can be controlled by (DECLAIM (OPTIMIZE (SPEED 0))). + ("An ounce of orthogonality is worth a pound of features.")
