indeed
float * bar3() {
const float * a = (float*) malloc(4*128);
const float * b = (float*) malloc(4*128);
float * c = (float*) malloc(4*128);
a = (const float*)__builtin_assume_aligned (a, 16, 0);
b = (const float*)__builtin_assume_aligned (b, 16, 0);
c = (float*)__builtin_assume_aligned (c, 16, 0);
for (int iat=0; iat<128; ++iat)
c[iat] = a[iat]+b[iat];
return c;
}
produces no aliases
