--- Comment #3 from Richard Biener <rguenth at gcc dot gnu.org> ---
Value numbering stmt = vect__68.15_89 = MEM <vector(2) double> [(double
RHS MEM <vector(2) double> [(double *)vectp_xyz_sRGB.12_85] simplified to {
1.4308039999999999647428694515838287770748138427734375e-1, 0.0 }
Setting value number of vect__68.15_89 to {
1.4308039999999999647428694515838287770748138427734375e-1, 0.0 } (changed)
