--- Comment #2 from DrTroll at gmx dot de --- @H.J. Lu I am aware, that _mm_broadcastsd_pd does the same as _mm_movedup_pd. However, maybe others are not. The fact that _mm_broadcastsd_pd is listed in the intel intrinsics guide and won't compile with GCC while all other relevant compilers (Intel, Clang, MSVC - tested all on Godbolt) accept it is probably suboptimal.
