Now that mpn_mul no longer dispatches to mpn_sqr, the squaring
optimization is missing in mpz_addmul/mpz_submul.
Thanks for spotting this!
mpz_addmul(sum, a, a);
This should be easy to fix.
It is. I fixed it with a small patch.

But I had to also add that case to the test program.
The case mpz_addmul(sum, a, a); was correctly handled,
but it wasn't tested.
And the case mpz_addmul(x, x, x); keeps on being untested!
Ĝis,
