Sorry, I forgot to answer to the list.

ah, and sorry for telling you so before looking on the list.

If the code is already there and some architectures can profit of it, especially in inner loops - why not just make it an optimisation flag?

Without even one good example where it is an improvement, this does not make sense. And even with an example: It degrades performance in other cases, so a module-wide flag would probably not cut it. Greetings, Joachim -- Joachim Breitner mail@joachim-breitner.de http://www.joachim-breitner.de/
