Another one - matrix multiplication:
/* A [NxM], B [MxP] */
#define DOLOOP(N, M, P) \
void matmul ## N ## M ## P(double *res, const double *A, const double *B) \
{ \
int i,j,k; \

Another trivial loop which is not unrolled but should be:
int f(int x)
{
int i, x1;
x1 = x;
for(i = 0;i<2;i++)
x1 *= x1;
return x1;
}

In 3.4 one was able to do this by specifying -fpeel-loops and got complete loop
peeling enabled. In 4.0 this is also the case, but only for the RTL unroller -
the tree unroller is not af

Really -funroll-loops should be added to -O3 by default and maybe a tweewed
version to -O2/-Os
(one which only unroll loops which can be unrolled fully and don't produce more
code than the loop
itself).
