fasl file version.
changes in sbcl-0.7.0 relative to sbcl-0.6.13:
+* incompatible change: The default fasl file extension has changed
+ to ".fasl", for all architectures. (No longer ".x86f" and ".axpf".)
* There are new compiler optimizations for various functions: FIND,
POSITION, FIND-IF, POSITION-IF, FILL, COERCE, TRUNCATE, FLOOR, and
CEILING. Mostly these should be transparent, but there's one
it will issue WARNINGs about the type mismatches. It's not clear
how to make the compiler smart enough to fix this in general, but
a workaround is given in the entry for 117 in the BUGS file.
+* The EVAL and EVAL-WHEN code has been largely rewritten, and the
+ old CMU CL "IR1 interpreter" has gone away. The new interpreter
+ is probably slower and harder to debug than the old one, but
+ it's much simpler (several thousand lines of source code simpler)
+ and considerably more ANSI-compliant. Bugs
+ ?? IR1-3 and
+ ?? IR1-3a
+ have been fixed. Since the code is newer, there might still be
+ some new bugs (though not as many as before Martin Atzmueller's
+ fixes:-). But hopefully any remaining bugs will be simpler, less
+ fundamental, and more fixable then the bugs in the old IR1
+ interpreter code.
+* DEFSTRUCT and DEFCLASS have been substantially updated to take
+ advantage of the new EVAL-WHEN stuff and to clean them up in
+ general, and are now more ANSI-compliant in a number of ways. Martin
+ Atzmueller is responsible for a lot of this.
+* A bug in LOOP operations on hash tables has been fixed, thanks
+ to a bug report and patch from Alexey Dejneka.
+* The default value of *BYTES-CONSED-BETWEEN-GCS* has been
+ doubled, to 4 million. (If your application spends a lot of time
+ GCing and you have a lot of RAM, you might want to experiment with
+ increasing it even more.)
+* PPRINT-LOGICAL-BLOCK now copies the *PRINT-LINES* value on entry
+ and uses that copy, rather than the current dynamic value, when
+ it's trying to decide whether to truncate output . Thus e.g.
+ (let ((*print-lines* 50))
+ (pprint-logical-block (stream nil)
+ (dotimes (i 10)
+ (let ((*print-lines* 8))
+ (print (aref possiblybigthings i) stream)))))
+ should truncate the logical block only at 50 lines, instead of
+ often truncating it at 8 lines.
+* :SB-CONSTRAIN-FLOAT-TYPE, :SB-PROPAGATE-FLOAT-TYPE, and
+ :SB-PROPAGATE-FUN-TYPE are no longer considered to be optional
+ features. Instead, the code that they used to control is always
+ built into the system.
+* The doc/cmucl/ directory, containing old CMU CL documentation,
+ is no longer part of the base system. The files which used to
+ be in the doc/cmucl/ directory are now available as
+ <ftp://sbcl.sourceforge.net/pub/sbcl/cmucl-docs.tar.bz2>.
+* lots of tidying up internally: renaming things so that names are
+ more systematic and consistent, converting C macros to inline
+ functions, systematizing indentation, making symbol packaging
+ more logical, and so forth
+* The fasl file version number changed again, for any number of
+ good reasons.
planned incompatible changes in 0.7.x:
* The debugger prompt sequence now goes "5]", "5[2]", "5[3]", etc.
instead of the old "5]", "5]]", "5]]]" sequence. (I was motivated
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
