Commit Message

8-byte modes should be processed only for TARGET_MMX_WITH_SSE.

gcc/ChangeLog:

    * config/i386/i386-expand.cc (expand_vec_perm_pblendv):
    Handle 8-byte modes only with TARGET_MMX_WITH_SSE.
    (expand_vec_perm_2perm_pblendv): Ditto.

Bootstrapped and regression tested on x86_64-linux-gnu {,-m32}.

Pushed to master.

Uros.
