ECL 13.5.1
==========
* Visible changes:
- ECL now reports #+UNIX for all compatible systems, including *BSD ones.
* Compiler fixes:
- Minor readability improvements in the C code.
- MULTIPLE-VALUE-BIND compiles using MULTIPLE-VALUE-SETQ and now both are
better optimized, generating simpler C code.
- The type checking routine for LOGAND was producing spurious warnings.
- (LDB (BYTE ...) ...) no longer conses a BYTE object.
- Added optimizations for MASK-FIELD, DPB, DEPOSIT-FIELD, LDB-TEST and LDB.
- CONSTANT-VALUE-P and friends now use the (compiler) environment.
- No optional type check generated for constant values.
- Declare the temporary variables in DEFMACRO/DESTRUCTURING-BIND as IGNORABLE
- ECL now accepts WHILE/IF before FOR/AS, a construct that is not ANSI
An example: (LOOP FOR I IN LIST WHILE (SOME-TEST I) FOR X = (F I) ... )
* Common Lisp fixes:
- CONSTANTP now performs a bit more work, macroexpanding forms.
- ENSURE-DIRECTORIES-EXIST ignores the host and device from the original
pathname when creating the directories.
- In FORMAT, printing of floating point numbers could lead to an infinite loop.
- ROUND, FLOOR, CEILING and TRUNCATE have been reorganized and work faster with
rational numbers.
- (CONCATENATE 'SIMPLE-BASE-STRING ...) returned an ordinary string.
- MAKE-ARRAY did not terminate strings with #\Null (needed internally by the C
code).
- (SETF DOCUMENTATION) did not operate on functions because the function object
documentation had precedence over the annotation.
- Added the whole Unicode character database to the C library. This means ECL
can now interpret all Unicode character names properly, and print them as
well. ECL now also recognizes all ASCII control-character abbreviations
- Print integers using upcase letters for radix > 10
- New functions RATIOP, {SINGLE,SHORT,DOUBLE,LONG}-FLOAT-P help avoid consing
in TYPEP
- HASH-TABLE-COUNT did not work with weak hashes: it did not update the count
of live cells (Note, however, that this function is by definition not
reliable, just a hint, since a garbage collection may happen while the count
is being computed)
- ECL no longer uses :READ-ONLY declarations in the SETF expansions because
there is code out there that modifies the values variables.
- PROGV can now 'unbind' variables when the list of variables is longer than
the list of values.
* CLOS:
- Added built in classes FIXNUM and BIGNUM.
- Eliminated code for accessing slots that was no longer used. Removed also
redundant code.
- Updating a class (due to a change in metaclass) now forces updating its
children
- UPDATE-INSTANCE-FOR-REDEFINED-CLASS received an alist instead of a
propertly-list as last argument
- PRINT-OBJECT did not have a working default for built in classes.
* Extensions:
- SYSTEM must use the POSIX shell, which usually lives in /bin/sh.
- CLX now uses recursive locks.
- ASDF upgraded to version 2.32, including the ASDF-BUNDLE facility, which
supersedes ECL's own implementation of precompiled libraries.
- MAKE-INSTANCE, SHARED-INITIALIZE, REINITIALIZE-INSTANCE now work on
structures as well.
