* a port to the Compaq/DEC Alpha CPU, thanks to Dan Barlow
* Martin Atzmueller ported Tim Moore's marvellous CMU CL DISASSEMBLE
patch, so that DISASSEMBLE output is much nicer.
+* The code in the SB-PROFILE package now seems reasonably stable.
+ I still haven't decided what the final interface should look like
+ (I'd like PROFILE to interact cleanly with TRACE, since both
+ facilities use function encapsulation) but if you have a need
+ for profiling now, you can probably use it successfully with
+ the current CMU-CL-style interface.
* Pathnames and *DEFAULT-DIRECTORY-DEFAULTS* are much more
ANSI-compliant, thanks to various fixes and tests from Dan Barlow.
Also, at Dan Barlow's suggestion, TRUENAME on a dangling symbolic
* Some math functions have been fixed, and there are new
optimizers for deriving the types of COERCE and ARRAY-ELEMENT-TYPE,
thanks to Raymond Toy's work on CMU CL, ported by Martin Atzmueller.
+* (There are also some new optimizers in contrib/*-extras.lisp. Those
+ aren't built into sbcl-0.6.13, but are a sneak preview of what's
+ likely to be built into sbcl-0.7.0.)
* A bug in COPY-READTABLE was fixed. (Joao Cachopo's patch to CMU
CL, ported to SBCL by Martin Atzmueller)
* DESCRIBE now gives more information in some cases. (Pierre Mai's
patch to CMU CL, ported to SBCL by Martin Atzmueller)
-* The code in the SB-PROFILE package has been substantially
- improved, although it's still unstable.
+* Martin Atzmueller and Bill Newman fixed some bugs in INSPECT.
* There's 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 byte fasl file version is now equal to the ordinary
fasl file version.
+changes in sbcl-0.7.0 relative to sbcl-0.6.13:
+* 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
+ potentially-annoying problem (bug 117): when the compiler inline
+ expands the FIND/POSITION family of functions and does type
+ analysis on the result, it can find control paths which have
+ type mismatches, and when it can't prove that they're not taken,
+ 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.
+
planned incompatible changes in 0.7.x:
* The debugger prompt sequence now goes "5]", "5[2]", "5[3]", etc.
