Isn't it possible to do something like:
vector (4, float) f0;
vector (4, float) f1;
- vector (4, int) ifres;
+ vector (4, __typeof (f0 > f1)) ifres;
f0 = (vector (4, float)){(float)argc, 1., 2., 10.};
f1 = (vector (4, float)){0., 3., 2., (float)-23};
test (4, f0, f1, ifres, "%f");
/* Double comparison. */
vector (2, double) d0;
vector (2, double) d1;
- vector (2, long long) idres;
+ vector (2, __typeof (d0 > d1)) idres;
d0 = (vector (2, double)){(double)argc, 10.};
d1 = (vector (2, double)){0., (double)-23};
test (2, d0, d1, idres, "%f");
