Web1) So long as doing a bitwise copy will exhibit the same side effects as memberwise copy would, the Standard allows trivial implicit copy constructors to do a memcpy instead of memberwise copies. 2) Some compilers actually do memcpy s instead of synthesizing a trivial copy constructor which does memberwise copies.
WebThe use of SIMD opcodes for memory work like this can have a massive performance impact, because they also include cache prefetches and other DMA hints that are important for optimizing bus access.
