common.h	[libc] Improve Cortex memset and memcpy functions (#149044) The code for memcpy is the same as in #148204 but it fixes the build bot error by using static_assert(cpp::always_false<decltype(access)>) instead of static_assert(false) (older compilers fails on static_assert(false) in constexpr else bodies). The code for memset is new and vastly improves performance over the current byte per byte implementation. Both memset and memcpy implementations use prefetching for sizes >= 64. This lowers a bit the performance for sizes between 64 and 256 but improves throughput for greater sizes.	1 年前
