/* On x86, division of one 64-bit integer by another cannot be
done with a single instruction or a short sequence. Thus, GCC
implements 64-bit division and remainder operations through
function calls. These functions are normally obtained from
libgcc, which is automatically included by GCC in any link
that it does.
Some x86-64 machines, however, have a compiler and utilities
that can generate 32-bit x86 code without having any of the
necessary libraries, including libgcc. Thus, we can make
Pintos work on these machines by simply implementing our own
64-bit division routines, which are the only routines from
libgcc that Pintos requires.
Completeness is another reason to include these routines. If
Pintos is completely self-contained, then that makes it that
much less mysterious. */

Let n, d, b, n1, and n0 be defined as in this function.
Let [x] be the "floor" of x. Let T = b[n1/d]. Assume d

= [(b[n1 % d] + n0)/d] + T, by definition of %

(1) Note that for any real x, integer i: [x] + i = [x + i].
To prevent divl() from trapping, [(b[n1 % d] + n0)/d] must
be less than b. Assume that [n1 % d] and n0 take their
respective maximum values of d - 1 and b - 1:
[(b(d - 1) + (b - 1))/d] < b
