--- Comment #1 from Reid Kleckner <[email protected]> ---
MSVC has a different model for intrinsics: they can always be called regardless
of the /arch: setting. Clang requires you to enable the relevant features.
There are no plans to implement the MSVC intrinsic model. LLVM subtarget
features are set at the function level. You can control them either with
__attribute__((target)) or the various -m* flags. There is no /arch: flag for
SSSE3, so your workaround is a proper solution.
