Possible speed improvements with sse optimized code

[Gerhard Kulzer-3]

Hello all developers,
a Happy New (and productive) Year I wish you all (:-))))

I just came across this article:
http://www.cortstratton.org/articles/OptimizingForSSE.php

I do not know how much digiKam algos are optimized already, but this article
seems do give some good recipes.

Hi Gerhard,

Happy New year too...

About SSE optimizations, this is relevant of Assembler programing, not C/C++.

This article is more dedicaced to optimize compiler (GCC) that we use to build target.

Assembler code is not portable and very complex to write/debug.

But few tips in this article can be used to optimize C/C++ programing to be compiled better later with GCC. but take a care : some tips can be understandable by others developpers if no comments are added into the code.

In general, i prefert writte a maintainable code instead an optimized but unreadable code (:=)))

Best

Gilles
