Snapshot 2014-04


The April snapshot has been tagged and binaries will be uploaded
soon.

Key changes:

 * This is the last snapshot that will include support for x87. After
   this, cmucl will only run on x86 chips that include support
   sse2. Sse2 was introduced with the Pentium 4 in 2001, 13 years ago.
 * The change in type derivation introduced in the last snapshot has
   been reverted. It's important to have (log -0d0) return
   -infinity+i*pi to get the branch cuts of the special funtions
   correct, using the definitions.  (CMUCL doesn't evaluate the
   functions directly from the definitions.)
 * Add more missing constants for double-double floats.

Removing x87 support

SSE2 has been supported by CMUCL since around 2008 and SSE2 was introduced
in the Pentium 4 in 2001. It's now time to drop support for x87.

I suspect x87 is rarely, if ever, used anymore since CMUCL will
automatically detect SSE2 and use that if your CPU supports. I rarely test
x87 except to see that it starts when a snapshot is made. Removing this
support will make the tarballs half as large (no x87 core anymore), a large
chunk of code can be removed as well as simplifying the hairy x86-assem.S
file.

If you need x87 support speak up!  No guarantees that we'll keep x87
support, but knowing that it's important to you will help.

The current plan is that the upcoming April snapshot will be the last
version that will ship with x87 support. After that, tarballs will not ship
with the x87 core file and we will begin removing support for x87.

[CfP] DEADLINE EXTENSION - 7th European Lisp Symposium


		 ELS'14 - 7th European Lisp Symposium
			 IRCAM, Paris, France

			    May 5-6, 2014

	       http://www.european-lisp-symposium.org/

     Sponsored by IRCAM, CNRS, UPMC, EPITA, LispWorks, Franz Inc.

Latest News:

* SUBMISSION DEADLINE EXTENDED. You have two more week to submit!

* Registration is now open. Early registration fee until April 13.
  See http://www.european-lisp-symposium.org/content-registration-full.html

The purpose of the European Lisp Symposium is to provide a forum for
the discussion and dissemination of all aspects of design,
implementation and application of any of the Lisp and Lisp-inspired
dialects, including Common Lisp, Scheme, Emacs Lisp, AutoLisp, ISLISP,
Dylan, Clojure, ACL2, ECMAScript, Racket, SKILL, Hop and so on. We
encourage everyone interested in Lisp to participate.

The 7th European Lisp Symposium invites high quality papers about
novel research results, insights and lessons learned from practical
applications, and educational perspectives. We also encourage
submissions about known ideas as long as they are presented in a new
setting and/or in a highly elegant way.

March snapshot


The March snapshot has been tagged and binaries will be uploaded soon.

The main changes are:

  * run-program accepts :element-type to specify the element type for
    the streams that are created.
  * Lisp-unit (a Lisp framework for testing) has been added as a
    contrib.  Use (require :lisp-unit) to compile and load it.
    Unlike asdf and defsystem, precompild fasls are not included.
  * Type derivation for log was not consistent with the values
    actually returned by log.  This is corrected now.
  * Double-double floats were missing the constants describing various
    limits such as least-positive-double-double-float.  These are
    added now.
  * When reading very small floats values, the reader will round to
    least-positive float if possible.  Otherwise an error is still
    signaled.

Year of the Horse snapshot


Happy Chinese New Year!

Just missed the first day of the Year of the Horse by a few days, but
the new 2014-02 snapshot has been tagged.  Also, we want to thank
Peter Buhr for allowing us to use his Blade 1500 to build and test
cmucl.  This month's snapshot was built on that machine.  Thanks!

Binaries will be uploaded soon.  

Some key changes are listed below.  Check the release notes for other
changes.

o Micro-optimizations in arithmetic vops for x86/sse2, reducing the
  number of memory loads in some cases.
o Run-time checks for zero pages are now disabled; the lazy zeroing of
  heap pages has been the default for some time without problems, so
  the run-time check is disabled.
o A serious error in the complex multiply vop on sparc has been fixed.

be uploaded soon.

Key changes for this snapshot:

o Type derivation for DECODE-FLOAT
o Use the C library sincos function for CIS, when available (linux,
  sparc). 
o Build for PPC on OSX 10.5

20e ppc binaries


Thanks to Carl for digging up a ppc box, the 20e binaries for ppc are
now available.

Don't know if ppc will get snapshots every month, but since it's much
faster than any sparc box I have access to, perhaps it will be kept
alive.
