Optimalization of "QuickSortSwap"

[kor...@gmail.com]

<english>
This is for me one of interresting things for me. How to optimalize the
code below? That's part of my QuickSortSwap() function. This function
is called many times in my implementation of QuickSort so i need most
effective implementation of this function. In this case is class T ==
unsigned int. The equivalent assembler code is generated for case that
T == unsigned int. One more time, i am asking: "Do you have any
suggestions how to optimalize the function bellow?". Btw, I am using
microsoft visual c++ 6.0.

Tohle je prvni priklad co by se mohlo nachazet v tehle googlegroup. Jak
optimalizovat kod zmineny nize? V podstate je to cast tzv. funkce
QuickSortSwap(), kterou mnohokrat volam ve sve implementaci QuickSortu,
takze mi jde o to, aby byla co nejvice efektivni. V tomto pripade je
datovy typ T == unsigned int. Ptam se jeste jednou : "Mate nejake
napady, jak optimalizovat, kod zmineny nize?". Mimochodem ja osobne
pouzivam microsoft visual c++ 6.0.
