I'm considering adding mpz_addmul_ui and mpz_submul_ui to mini-gmp.
This can be implemented either
* in terms of mpn_addmul_1 and mpn_submul_1 (and then I also need the
additional primitives, mpn_mul_1c and mpn_neg). I have some untested
code, roughly 120 lines.
* in terms of mpz_mul_ui, mpz_add and mpz_sub, with an additional mpz_t
temporary. Would be at most 20 lines.
What makes most sense? In any case, testcases are needed too; so I'm not
sure I'll get the time to actually implement it soon.
