[armedbear-devel] Patch for LispThread.java, do not copy arrays in StackFrame
by Ville Voutilainen 29 Jul '09

29 Jul '09

Here's a very simple patch that should make function calls faster. I have only anecdotal tests with the raytracing shootout test and the compiled ansi-tests, but the numbers seem to support this patch. If nobody objects, I'll commit this.

Here's a stab at checking initargs for make-instance and others. With this patch, I get rid of the following errors: -CHANGE-CLASS.1.11 -MAKE-INSTANCE.ERROR.3 -MAKE-INSTANCE.ERROR.4 Feel free to comment.

[armedbear-devel] false-positive ansi tests
by Peter Tsenter 28 Jul '09

28 Jul '09

It seems abcl generates correct result on some ANSI tests, but in actuality abcl fails. The way tests are written, it's hidden from the user. Example: disassemble.4 If one executes (disassemble-it (eval '(function (lambda (x y) (cons x y))))) as it's written then everything looks ok, but (disassemble (eval '(function (lambda (x y) (cons x y))))) returns the following ; 'jad' is not recognized as an internal or external command, ; operable program or batch file.

It didn't matter whether interpreter or compiled, because both had the same issue. Anyway, thanks for the report! It's fixed now. Bye, Erik.

I can see the error in the compiler; it's in p2-unwind-proctect: the exception handler doesn't save the values register of the thread. Maybe it's the same in the interpreter. I'll have a look later today, if I have time. Thanks for the report! Bye, Erik.

[armedbear-devel] progress on Maxima + ABCL -- light at the end of the tunnel!
by Robert Dodier 27 Jul '09

27 Jul '09

Hi, I've compiled Maxima (from CVS) with ABCL (from svn) and run_testsuite() shows just a few errors due to different floating point results. Hurray! The key change to Maxima seems to have been changing EQ to EQUAL in a pattern-matching function ... In ABCL it appears that numbers are not necessarily EQ so a lot of patterns failed. Since the pattern-matching stuff is widely used in Maxima (especially integrals) there were a lot of failed tests. Just that one change seems to have fixed dozens of test failures! I found it necessary to run the autoconf machinery (sh bootstrap && ./configure at least; I ran make as well, although I don't know if that's actually necessary, and then I ran configure.lisp as described in INSTALL.lisp) before compiling with ABCL via: (require 'asdf) (asdf:operate 'asdf:load-op :maxima) Without the autoconf stuff, src/autoconf-variables.lisp has incorrect values, it seems. Maxima + ABCL is extremely slow -- something like 7 times slower than Maxima + Clisp, which is the slowest of the established Lisp implementations I've tried (GCL, ECL, SBCL, CMUCL, and Clisp). I'm working on Linux, maybe it helps to run on Windows -- I'm thinking the Java implementation might be faster. Just a guess. I'm pretty excited about the possibilities here. A long-term project is to organize Maxima into modules in hopes of making it possible to load different modules a la carte -- I think that might make it attractive for bolting it onto different projects. Thanks to the ABCL developers for all their work. best Robert Dodier Maxima developer

[armedbear-devel] Deploying compiled ABCL apps/elements
by Matt Lamari 26 Jul '09

26 Jul '09

What is the mechanism for converting source code or an in-memory image (or fragment thereof) into a deployable unit? Just point me at a function name/document and I can take it from there. . . . Thanks, Matt

[armedbear-devel] Problem loading Lisp file on Mac, but works on Windows
by Paul Reiners 25 Jul '09

25 Jul '09

I've written a Java program that calls a Lisp program. On Windows, this works just fine. However when I run it on Mac OS X, I get this error: Error loading /Users/paul/Documents/workspaces/MyOpenSourceProjects/ JVMLanguages/src/life.lisp at line 53 (offset 1628) Debugger invoked on condition of type END-OF-FILE: #<END-OF-FILE {51190A}> [1] CL-USER(1): Any idea what is going wrong here? I wrote both the Lisp and Java files on Windows originally. Is it some sort of character encoding problem? Here are the relevant files: http://automatous-monk.cvs.sourceforge.net/viewvc/automatous-monk/JVMLangua… http://automatous-monk.cvs.sourceforge.net/viewvc/automatous-monk/JVMLangua… Paul

[armedbear-devel] Holidays or the release of 0.16?
by Erik Huelsmann 25 Jul '09

25 Jul '09

With the normal release schedule, it would be time to release 0.16 in 1 or 2 weeks. However, I'll be travelling with unknown amounts of net time around that time. Until then, I'll be busy with work and travel preparations. So, we have 2 options here: 1. One of the other committers steps up and makes the release Most of our release process is documented in the wiki. What's not there can be added until then 2. We delay 0.16 until some time I have time to create the release. With kind regards, Erik.

[armedbear-devel] second version of the StackFrame cleanup
by Ville Voutilainen 23 Jul '09

23 Jul '09

Same as before, but use a vararg function instead of doing manual arrays. Java does correctly choose a multi-param version when it's available, it only uses a vararg version when it has to.
