--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> --- The only place where SLP vectorizer happens is in func creating: ``` _11 = (unsigned intD.11) &_ZL4buf4D.7612; _12 = (unsigned intD.11) &_ZL4buf5D.7613; _13 = (unsigned intD.11) &_ZL4buf7D.7615; _14 = (unsigned intD.11) &_ZL4buf1D.7609; _15 = {_14, _13, _12, _11}; ... MEM <vector(4) unsigned int> [(unsigned char * *)&struct1] = _15; ``` What TER does expands the above gimple all together.
