Tunguska the ternary emulator

[Shaos]

OK, and I'll check current code under MacOS X 10.4 on my PowerBook G4

I checked - bad news
MacOS X 10.4 has older bison version 1.28 that doesn't create cpp/hpp, instead it creates c/h files and I can't compile it even after renaming...

After installation from sources m4-1.4.13 (with symlink /usr/local/bin/gm4 to m4) and bison-2.4.1 Tunguska was compiled:

it's working, but very slow (in the beginning 10-15 seconds per frame, then about 5 seconds per frame).

As you have no doubt noticed, not a lot has happened with this project for ages (well, in fact, nothing at all has happened). I've been quite busy with other projects and my physics studies, and now on top of that I'm working on my master's thesis, which is eating a lot of time, so things will likely remain slow at least until my thesis is finished (in January).

Just figured I'd make some sort of official statement, so you guys don't think I've been run over by a bus or something.

[Shaos]

Good news!
By the way, any ideas as to do Tunguska faster on Mac?

[Mac Buster]

I am happy to know you're not dropped the project Will wait for new Tunguska releases.

[Mac Buster]

By the way, any ideas as to do Tunguska faster on Mac?

It is fairly easy - take a faster Mac

My Mac is relatively fast - it's PowerPC G4 1.67 GHz...

The work on my thesis sort took longer than I had planned. It's now mostly done, and the classes I'm taking now have been quite demanding, but hopefully I'll be able to put real work into Tunguska towards the end of this month.

It's very frustrating to be away from programming for this long. I have so many ideas, and my programming fingers are itching to get to work.

I'm doing some small performance testing work on various algorithms at the moment, to get hard figures on which method of doing ternary logic in host-native integers is the best.

As for mac performance, I honestly have no idea.

The people that were hosting the tunguska website has had a disk crash, so it's down for the time being. Apparently they're working on restoring stuff from the backups now.

Just figured I'd let you guys know I haven't disowned the page or anything.

[eudoxie]

I've moved the tunguska website to sourceforge hosting, as my acc.umu.se account will soon expire, as well as updated the freshmeat page to reflect this change.

I also patched some bit rot on the CVS so that it compiles with newer GCC versions.

Hm, I'm not quite sure what to do about that one, as it's code that has been generated by flex and not by me. Could be that slackware is using versions of gcc and flex that don't play nice together.

My flex version defines EOF as -1, I suppose you could compile with -DEOF=-1 as a temporary fix.

I have the same flex version, bison 2.4.1 and gcc 4.5.2.

What's your GCC version?

Also, try adding

Code: Select all

#ifndef EOF
# define EOF -1
#endif

just above "extern YYSTYPE yylval" in scanner.l, see if that works (it's a bit of an ugly fix, but my version doesn't complain about it and builds a working assembler)

[Shaos]

yes, it's working

P.S. my gcc is 4.5.2

[eudoxie]

I pushed some minor changes to the CVS. Mostly moving a bunch of small objects off the heap to the stack, where good programming practice dictates they belong. Shouldn't affect performance or functionality.
