Power Developer :: libfreevec 1.0.3 & benchsuite 1.0.2 released!

Also I noticed that sometimes you use random() that is not ANSI standard instead of rand() and INT_MAX and CHAR_MAX instead of RAND_MAX.

Fixed thanks again :)

And why in strcmp reported alighnments are -1 and 0?

Where exactly do you mean?

I'm sorry it was pos and type, not al_src and al_dst...
Anyway I didn't understand how strcmp may be visualized in one graph...

I've just prepared some graphs from my PowerBook G4 1.67 GHz (for bmove512, memcpy, memset, strcpy, strlen):

Wow, the G4 at that speed performs very nicely. If you could send me the CSV data, I'd gladly include the charts in freevec.org with a link to your blog :)

Thanks! This is archive with CSVs, GIFs and sqlite3's benchmarks.db (and also dumped SQL). I run these benchmarks only for 6 functions (including strcmp, but this one was not good probably because of my random.dat had zeros sometimes and I didn't render image for it):

Later I will publish the same tests for PowerMac G4 400MHz and will run full benchsuite from your SVN on PowerBook G4 1.67GHz.

Well, if I got all the cases it would need many special graphs, but I only included the case where comparing equal strings. Perhaps I should include more graphs :-/ Quote: I've just prepared some graphs from my PowerBook G4 1.67 GHz (for bmove512, memcpy, memset, strcpy, strlen): http://shaos.net/blog/2008/04/some-vect ... ok-g4.html Wow, the G4 at that speed performs very nicely.

On my and your data I see strange peak for G4 vectorized unaligned (!) strcpy for size 6144. Why is it so strange?
