Why it isn't optimized to memcpy? If the lhs is unused, it always should be folded to memcpy, regardless of whether mempcpy is fast or not (I assume no target has slow memcpy and fast mempcpy). Jakub
WebI've noticed by using systics for time measurements, that memcpy provides better timing than DMA. for example. I have 16bit array of 64 elements to send. by memcpy the transer lasted 293systics by DMA 973systics i only activate the DMA and wait for the status to change. Thanks for assistance !!

Web由于该函数比memcpy安全的一点在于要考虑内存是否重叠,如果重叠则反向copy避免还没有copy的地方被覆盖. 实现要点: 检查是否内存重叠,如果没有重叠,则直接调用memcpy. 如果重叠,则从src+len,到dst+len倒序copy. 此时不能利用memcpy,因为memcpy是正向copy的. mayor betsy stixWebnext prev parent reply other threads:[~2024-03-03 14:14 UTC newest] Thread overview: 13+ messages / expand[flat nested] mbox.gz Atom feed top 2024-03-03 14:14 [PATCH 1/4] x86: kmsan: Don't rename memintrinsics in uninstrumented files Alexander Potapenko 2024-03-03 14:14 ` [PATCH 2/4] kmsan: another take at fixing memcpy tests Alexander ... mayor betsy priceWeb14 dec. 2024 · The memcpy function is used to copy a block of data from a source address to a destination address.
