It's the unaligned access and the change / improvements to the memcpy that *might* help in this case. But that ofcourse depends on the compiler knowing when it can do such a thing. Ofcourse what might be more interesting is the kind of workload analysis that Dave's done in the past with memcpy to know what the alignment and size of the buffer being copied is. cheers Ramana > > -- Michael > > _______________________________________________ > linaro-toolchain mailing list > linaro-toolchain@lists.linaro.org > http://lists.linaro.org/mailman/listinfo/linaro-toolchain > _______________________________________________ linaro-toolchain mailing list linaro-toolchain@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-toolchain
