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?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): http://shaos.net/blog/2008/04/some-vect ... ok-g4.html |

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

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 :)

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

More than 2 days (and nights ;) of running benchsuite on my PowerBook G4 1.67 GHz:http://shaos.net/blog/files/g4_1670_080428.zip (560K) |
