5702 bit pattern would be 128.
5704 This is the right choice when operating on groups of INTEGER_CSTs
5705 that might have different signedness or precision. It is also the
5706 right choice in code that specifically needs an approximation of
5707 infinite-precision arithmetic instead of normal modulo arithmetic.
5709 The approximation of infinite precision is good enough for realistic
5710 numbers of additions and subtractions of INTEGER_CSTs (where
5711 "realistic" includes any number less than 1 << 31) but it cannot
5712 represent the result of multiplying the two largest supported
5713 INTEGER_CSTs. The overflow-checking form of wi::mul provides a way
5714 of multiplying two arbitrary INTEGER_CSTs and checking that the
5715 result is representable as a widest_int.

5718 the range of widest_int rather than the range of a TREE_TYPE.

5744 This is the right choice when operating on bit or byte counts as
5745 untyped numbers rather than M-bit values. The wi::to_widest comments
5746 about addition, subtraction and multiplication apply here: sequences
5747 of 1 << 31 additions and subtractions do not induce overflow, but
5748 multiplying the largest sizes might. Again,

5764 In contrast to the approximation of infinite-precision numbers given
5765 by wi::to_widest and wi::to_offset, this function treats T as a
5766 signless collection of N bits, where N is the precision of T's type.
5767 As with machine registers, signedness is determined by the operation
5768 rather than the operands; for example, there is a distinction between
5769 signed and unsigned division.
5771 This is the right choice when operating on values with the same type
5772 using normal modulo arithmetic. The overflow-checking forms of things
5773 like wi::add check whether the result can be represented in T's type.
5775 Calling this function should have no overhead in release builds,
5776 so it is OK to call it several times for the same tree. If it is
5777 useful for readability reasons to reduce the number of calls,
