6151 This function gives T's actual numerical value, influenced by the
6152 signedness of its type. For example, a signed byte with just the
6153 top bit set would be -128 while an unsigned byte with the same
6154 bit pattern would be 128.
6156 This is the right choice when operating on groups of INTEGER_CSTs
6157 that might have different signedness or precision. It is also the
6158 right choice in code that specifically needs an approximation of
6159 infinite-precision arithmetic instead of normal modulo arithmetic.
6161 The approximation of infinite precision is good enough for realistic
6162 numbers of additions and subtractions of INTEGER_CSTs (where
6163 "realistic" includes any number less than 1 << 31) but it cannot
6164 represent the result of multiplying the two largest supported
6165 INTEGER_CSTs. The overflow-checking form of wi::mul provides a way
6166 of multiplying two arbitrary INTEGER_CSTs and checking that the
6167 result is representable as a widest_int.
6169 Note that any overflow checking done on these values is relative to
6170 the range of widest_int rather than the range of a TREE_TYPE.
6172 Calling this function should have no overhead in release builds,
6173 so it is OK to call it several times for the same tree. If it is
6174 useful for readability reasons to reduce the number of calls,
6175 it is more efficient to use:

6194 the target's address size in bits.
6196 This is the right choice when operating on bit or byte counts as
6197 untyped numbers rather than M-bit values. The wi::to_widest comments
6198 about addition, subtraction and multiplication apply here: sequences
6199 of 1 << 31 additions and subtractions do not induce overflow, but
6200 multiplying the largest sizes might. Again,
