as per Daniel Barlow's suggestion and Martin Atzmueller's patch
changes in sbcl-0.6.12 relative to sbcl-0.6.11:
+* incompatible change: The old SB-EXT:OPTIMIZE-INTERFACE declaration
+ is no longer recognized. 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
-?? improved support for intersection types, fixing bug 12 (E.g., now
- (SUBTYPEP 'KEYWORD 'SYMBOL)=>T,T.)
-?? The :PROPAGATE-FLOAT-TYPE and :PROPAGATE-FUN-TYPE features
+* 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!)
-?? unscrewed floating point infinities (bug 13) in order to support
- :PROPAGATE-FLOAT-TYPE and :PROPAGATE-FUN-TYPE features
-?? some minor ANSIfication of type specifications: bare 'AND and 'OR
- are no longer valid type specifiers, so e.g. (TYPEP 11 'AND) now
- signals an error; and SATISFIES requires its predicate to be a
- symbol, not a function object
+* 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)
-* a new workaround to make the cross-compiler portable to CMU CL
- again despite its non-ANSI EVAL-WHEN, thanks to Martin Atzmueller
-* new fasl file format version number (because of changes in byte
- code opcodes and in internal representation of (OR ..) types)
+* 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
+ <http://www-jcsu.jesus.cam.ac.uk/ftp/pub/debian/lisp>.
+ 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.")
