Hi Gerhard,

Happy New year too...

About SSE optimizations, this is relevant of Assembler programing, not

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 (:=)))
