Trunk gives:
vect_cst__42 = {a_13(D), a_13(D), a_13(D), a_13(D)};
vect__4.7_41 = MEM <vector(4) float> [(float *)x_12(D)];
vect__7.11_46 = MEM <vector(4) float> [(float *)y_14(D)];
vect__8.12_47 = .FMA (vect__4.7_41, vect_cst__42, vect__7.11_46);
MEM <vector(4) float> [(float *)y_14(D)] = vect__8.12_47;
vect_cst__72 = {a_13(D), a_13(D)};
vect__10.19_71 = MEM <vector(2) float> [(float *)x_12(D) + 16B];
vect__33.23_77 = MEM <vector(2) float> [(float *)y_14(D) + 16B];
vect__34.24_78 = .FMA (vect__10.19_71, vect_cst__72, vect__33.23_77);
MEM <vector(2) float> [(float *)y_14(D) + 16B] = vect__34.24_78;
_59 = MEM[(float *)x_12(D) + 24B];
_62 = MEM[(float *)y_14(D) + 24B];
_63 = .FMA (a_13(D), _59, _62);
MEM[(float *)y_14(D) + 24B] = _63;
For the 7 case.
