Merge code from main branch of 2005-12-17 to ppc gencgc branch.  Still
doesn't work of course.
1 rtoy 1.1 ========================== C M U C L 19 d =============================
5     The CMUCL project is pleased to announce the release of CMUCL 19d.
6     This is a major release which contains numerous enhancements and
7 emarsden 1.4 bugfixes from the 19c release.
8 rtoy 1.1
9     CMUCL is a free, high performance implementation of the Common Lisp
10     programming language which runs on most major Unix platforms. It
11     mainly conforms to the ANSI Common Lisp standard. CMUCL provides a
12     sophisticated native code compiler; a powerful foreign function
13     interface; an implementation of CLOS, the Common Lisp Object System,
14     which includes multimethods and a metaobject protocol; a source-level
15     debugger and code profiler; and an Emacs-like editor implemented in
16     Common Lisp. CMUCL is maintained by a team of volunteers collaborating
17     over the Internet, and is mostly in the public domain.
19     New in this release:
22     * Feature enhancements:
24     - Destructive functions like nreverse that modify constant args
25     will produce a warning.
26     - Destructive functions like nreverse whose results are not used
27     will produce a warning.
28     - Pathnames that cannot be printed readably using #p"..." will
29     now be printed using the CMUCL extension #P(...). However,
30     there are still cases where CMUCL cannot print pathnames
31     readably, but these involve search-lists and patterns.
32 rtoy 1.3 - LONG-LONG and UNSIGNED-LONG-LONG are recognized types in the
33     C-CALL package for signed and unsigned 64-bit integers.
34 rtoy 1.1
35     * Numerous ANSI compliance fixes:
37     - A reader-error is signaled if the number that is being read is
38     too small to be presented. We used to silently return 0.
39     - WITH-INPUT-FROM-STRING no longer modifies the index if
40     WITH-INPUT-FROM-STRING is not exited normally.
41     - An error is signaled if a declaration is used as the name of a
42     deftype, condition, or defstruct, and vice versa.
43     - An error is signaled when trying to generate a namestring from
44     a pathname with just a version component (other than nil,
45     :newest, or :unspecific). CMUCL cannot print that readably.
46     - FLET and LABELS functions will catch errors in keyword
47     parameters. Previously, a keyword of NIL was silently
48     accepted.
49     - Printing a zero using ~E will now include a trailing zero
50     after the decimal point, as required by CLHS,
51 rtoy 1.2 - DOCUMENTATION and (SETF DOCUMENTATION) now works for
52     structures of type list or vector.
53 rtoy 1.3 - DOTIMES will execute the loop the specified number of times,
54     independent of what the loop might do to the loop counter.
55 rtoy 1.1
56     * Numerous bugfixes:
58     - LISTEN on DUAL-CHANNEL-SIMPLE-STREAM should work now.
59     - Some numerical issues with the two-arg log function have been
60     fixed. (log 17 10f0), (log 17f0 10) and (log 17 10) all
61     return the same result now.
62     - DESTRUCTURING-BIND no longer causes an error when the list to
63     be destructured is circular.
64 rtoy 1.2 - PEEK-CHAR for Gray streams handles end of file correctly now.
65     - For the ppc port, the alignment of objects in alien structures
66     now matches the PowerOpen ABI for Mac OS X.
67 rtoy 1.3 - For Darwin/ppc, CMUCL was not following the ABI when calling
68     out to C varargs functions. Now we always copy any float args
69     to the corresponding int regs (or stack) as required by the
70     ABI. This isn't necessary for non-varargs functions, but
71     CMUCL doesn't know functions which are varargs functions.
72     - Callbacks with long-long args or results should work correctly
73     now for Darwin/ppc.
74 rtoy 1.1
75     * Other changes:
77     - CMUCL catches more cases where it cannot print a pathname
78     readably. In particular when the pathname name contains "/"
79     or ".", or when the pathname type contains a ".".
81     * Improvements to the PCL implementation of CLOS:
83     * Changes to rebuilding procedure:
84     - Build scripts should recognize FreeBSD automatically.
85     - Should be able to build on either Mac OS X 10.2 or 10.4 using
86     the default version of gcc.
88     This release is not binary compatible with code compiled using CMUCL
89 emarsden 1.4 19c; you will need to recompile FASL files.
90 rtoy 1.1

92     guidelines on reporting bugs, and mailing list details.
95     We hope you enjoy using this release of CMUCL!
