        PR target/85572
        * config/i386/i386.c (ix86_expand_sse2_abs): Handle E_V2DImode and
        E_V4DImode.
        * config/i386/sse.md (abs<mode>2): Use VI_AVX2 iterator instead of
        VI1248_AVX512VL_AVX512BW.  Handle V2DImode and V4DImode if not
        TARGET_AVX512VL using ix86_expand_sse2_abs.  Formatting fixes.
