inplace operators for GF(p),GF(p^n) and MPolynomial_libsingular #967
Description
The attached patches implement inplace operators for IntegerMod, FiniteFieldElement_givaro and MPolynomial_libsingular.
Some timings for GF(q)
Before:
sage: k.<a> = GF(2^15)
sage: A = [a^i for i in range(k.order())]
sage: %timeit _ = sum(A)
100 loops, best of 3: 6.79 ms per loop
After:
sage: k.<a> = GF(2^15)
sage: A = [a^i for i in range(k.order())]
sage: %timeit _ = sum(A)
100 loops, best of 3: 2.05 ms per loop
Component: basic arithmetic
