8:42:24 frgo Hi.

8:42:49 frgo After pullinbg from dev I get an error from waf configure.

8:42:53 frgo UnboundLocalError: local variable 'clasp_gc_filename' referenced before assignment

8:43:01 beach Hello frgo.

8:43:12 frgo Hi beach.

8:44:29 frgo I'd look into that error myself but we are now arriving at Hammerfest and we are making a sight seeing tour through that town...

8:44:58 frgo Beach, all - see you later ...

9:09:06 beach Oh, I have a better idea for the inlining-by-local-graph-rewriting technique. It will work for assignments and for references to free variables as well. And for loops.

9:40:26 Shinmera beach: By the way, the assistant /finally/ said that he definitely won't supervise my thesis last week, so now I'm back to square one, trying to find someone.

9:40:45 Shinmera Actually wait that was this week, Wednesday. I'm getting my stuff mixed up.

9:56:39 beach Shinmera: Sorry to hear that.

9:57:20 beach Shinmera: Your considering it made me work out an algorithm, so it had some good consequences after all. At least for me.

9:57:27 Shinmera I don't understand how 100+ students are supposed to find a bachelor's thesis here. Almost nothing is posted, and most of the profs you talk to either don't really have much of an idea, no time, or don't like your ideas, or all of the above.

9:57:52 beach Yeah, that sounds difficult.

9:58:31 Shinmera Anyway, I'm in talk with other people now, so hopefully I can find something sometime soon-ish. Sigh.

10:07:20 beach Yeah, good luck!

10:07:41 Shinmera Thanks

11:41:06 drmeister Hello

11:55:19 beach Hello drmeister.

12:04:15 beach New figures for new inlining technique: fig21.pdf - fig27.pdf on the metamodular site. I don't dare type the URL because I was considered a spammer by freenode when I did that.

12:04:41 beach The new technique can handle loops, assignments, and references to free variables.

12:05:09 Shinmera beach: Wow, Freenode must have been cracking down hard on spammers then

12:05:44 beach I did posts 5 links in a row without any other text.

12:06:07 Shinmera Ah. That'll do it.

12:06:57 Shinmera Yeah, they recently made a change in policy. Posting lines too frequently gets you automatically banned.

12:08:16 beach I see.

12:09:17 beach The new technique copies the entire lexical environment of the callee into the caller. It keeps a mapping between callee instructions and caller instructions to avoid copying an instruction multiple times.

12:10:41 beach The CALL to be inlined, copies the entire copied callee environment to the callee so that execution can be resumed in the callee at any point, thus allowing partial inlining.

12:11:12 beach That is a bit overkill, because it would be enough to copy the live variables.

12:17:12 beach The technique obviously doesn't work for recursive functions. Exercise for the reader: In what other situations does it not work?

12:34:38 beach Hint: What if some variables in the callee environment are captured by a closure?
