http://p4web.freebsd.org/@@1203489?ac=10 Change 1203489 by jmg@jmg_carbon2 on 2014/12/04 00:30:34 add an emulation of _mm_insert_epi64 for i386... Why they didn't add an pinsrdq which could only load from memory or something similar is beyond me... This gets things compiling and working on i386 again...
