--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
The vectorizer produces:
vectp_pBE.28_115 = (unsigned char[48] *) ivtmp.73_338;
_218 = ivtmp.68_335 + 1;
vectp_pCSI2.19_107 = (unsigned char[48] *) _218;
vectp_pCSI2.10_98 = (unsigned char[48] *) ivtmp.68_335;
vect_array.12 = .LOAD_LANES (MEM <unsigned char[48]> [(uint8_t
*)vectp_pCSI2.10_98]);
vect__1.13_100 = vect_array.12[0];
vect__1.14_101 = vect_array.12[1];
vect__1.15_102 = vect_array.12[2];
vect_array.12 ={v} {CLOBBER};
vect__4.16_103 = vect__1.14_101 >> 4;
vect__22.17_104 = vect__1.15_102 << 4;
vect__5.18_105 = vect__4.16_103 | vect__22.17_104;
vect_array.21 = .LOAD_LANES (MEM <unsigned char[48]> [(uint8_t
*)vectp_pCSI2.19_107]);
vect__6.22_109 = vect_array.21[0];
vect__6.23_110 = vect_array.21[1];
vect_array.21 ={v} {CLOBBER};
Here vect__6.22_109 is the same as vect__1.14_101 and vect__6.23_110 is the
same as vect__1.15_102 (if I did this correctly).
