20  sc_unsigned.h -- Arbitrary precision unsigned arithmetic.
21 
22  This file includes the definitions of sc_unsigned_bitref,
23  sc_unsigned_subref, and sc_unsigned classes. The first two classes
24  are proxy classes to reference one bit and a range of bits of a
25  sc_unsigned number, respectively.
26 
27  An sc_signed number has the sign-magnitude representation
28  internally. However, its interface guarantees a 2's-complement
29  representation. The sign-magnitude representation is chosen
30  because of its efficiency: The sc_signed and sc_unsigned types are
31  optimized for arithmetic rather than bitwise operations. For
32  arithmetic operations, the sign-magnitude representation performs
33  better.
34 
35  It is also important to note that an sc_unsigned number with n
36  bits is equivalent to an sc_signed non-negative number with n + 1
37  bits.
38 
39  The implementations of sc_signed and sc_unsigned classes are
40  almost identical: Most of the member and friend functions are
41  defined in sc_nbcommon.cpp and sc_nbfriends.cpp so that they can
42  be shared by both of these classes. These functions are chosed by
43  defining a few macros before including them such as IF_SC_SIGNED
44  and CLASS_TYPE. Our implementation choices are mostly dictated by
45  performance considerations in that we tried to provide the most
46  efficient sc_signed and sc_unsigned types without compromising
47  their interface.
48 
49  For the behavior of operators, we have two semantics: the old and
50  new. The most important difference between these two semantics is
51  that the old semantics is closer to C/C++ semantics in that the
52  result type of a binary operator on unsigned and signed arguments
53  is unsigned; the new semantics, on the other hand, requires the
54  result type be signed. The new semantics is required by the VSIA
55  C/C++ data types standard. We have implemented the new semantics.

1270  sn = { int64, long, int, char* }, and

1275  s OP u -> u s OP u -> s
1276  u OP s -> u u OP s -> s
1277  s OP s -> s s OP s -> s

1285  In the new semantics, the result is u if both operands are u; the
1286  result is s otherwise. The only exception is subtraction. The result
1287  of a subtraction is always s.
1288 
1289  The old semantics is like C/C++ semantics on integer types; the
