--- Comment #1 from Marc Glisse <glisse at gcc dot gnu.org> ---
Turning all the comparisons into a<0 is something we do already at the GIMPLE
level for scalars. Some more restricted form should extend to vectors.
For the combination movmsk(x<0), we could add such an insn to sse.md, which
would generate only movmsk, or we could transform movmsk(x<0) into movmsk(x).
