new Cog VMs available

in http://www.mirandabanda.org/files/Cog/VM/VM.r2487/.

Fix bugs described in the "[Pharo-project] Troubles with #flushCache and

#run:with:in:" thread http://lists.gforge.inria.fr/pipermail/pharo-project/

2011-July/050858.html. The PIC machinery wrongly treated invoke-as-method

sends as MNUs.

Closely related, finally fully implement PIC MNU cacheing where, by calling a

special abort, a PIC is able to record that a gven selector is an MNU for a

particular class. Speeds up a simple MNU benchmark by 33% (with more

performance the deeper the receiver's cass hierarchy is).

On Mac fix mis-editing of Info.plist to insert revision info so that VM .app

once again starts on 10.5.x.

Re: [squeak-dev] new Cog VMs available

Hi Eliot,

This is great news. I am totally happy that I can get accurate
coverage data again :-)

Unfortunately there is a new problem: The VM sometimes crashes when
running the coverage analysis. I am using the same test setup
(http://jenkins.lukas-renggli.ch/job/PetitParser/lastSuccessfulBuild/artifact/petitparser.zip)
that I described in my previous mail. Using the TestRunner about 1 in
5 times running the coverage analysis on AST-Tests-Semantics crashes
the VM. Programmatically it also happens, but even less often:

runner := TestRunner new.
runner categoryAt: 8 put: true.
runner runCoverage

I've also attached the "crash.dmp" the VM generates.

Anyway, cog rocks. Thanks a lot for your continuous efforts on making
it the best Smalltalk VM out there.

Lukas

Sounds great. Does it work with #cannotInterpret:?

In theory ;). Test it and see. If it fails, point me at the test ;). [at ESUG; wish you were here, Levente]
