As showed here, http://oprofile.sourceforge.net/examples/
There are some other events in oprofile on ARMv7, that we can have a try to get more information on time usage of memcpy() and strcpy(). http://oprofile.sourceforge.net/docs/arm-v7-events.php I am not familiar with ARM arch and these hardware events on ARM, but I think some of them should be useful for us. > If we can get twice the performance out of strcpy() and memcpy() then > the Dhrystone result should go up by almost 30 %. It would make a > nice headline at least :) Yeah, absolutely. _______________________________________________ linaro-toolchain mailing list linaro-toolchain@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-toolchain
