No, that should be fine.

What is wrong when you do that? Are there errors when you build? Does Phobos not seem to be taking advantage of the SSE operations?

In phobos/internal/array{byte, double, float, int, short}.d, you need to uncomment the sections labelled "version (D_InlineAsm_X86)" to enable the ASM code.
