FK> Well, older fpcs had this for mmx. Since I never saw bug reports about FK> it, I thought nobody used it so we didn't implement it for sse so far :) Ugh, this is rather fpc-pascal question, but: how can I demand (or just hope for) putting specific data to xmm register? Is assembler the only solution? If so, (this is even more fpc-pascal question with fpc-devel subquestion) what docs/soft was used for FPC compiler optimizing (for me the hard part is cycles counting: even for small portions of code it's not easy to estimate prefetches and others)? Is intel vtune designed for this task for linux/windows on intel processors? Would it be of any help, if I submit obviously not optimal processor specific asm code examples generated by FPC if I find any? If so, should I present only 2.1.x comments? _______________________________________________ fpc-devel maillist - [email protected] http://lists.freepascal.org/mailman/listinfo/fpc-devel
