    gcc/ChangeLog:
    
            * config/i386/i386.md (*load_tp_x32_zext, *add_tp_x32_zext,
            *tls_dynamic_gnu2_combine_32): Fix empty split condition.
            * config/i386/sse.md (*<sse2_avx2>_pmovmskb_lt,
            *<sse2_avx2>_pmovmskb_zext_lt, *sse2_pmovmskb_ext_lt,
            *<sse4_1_avx2>_pblendvb_lt): Likewise.
