| ASIS_Expression_Resolver calculates the numeric value of an ASIS
expression
(i.e., where the Element_Kind() is An_Expression) if one can be
semantically determined. Integer and floating point literals, named
numbers, initialization expressions, 'First and 'Last values, and
mathematical expressions can all be processed. Enumeration and
character
expressions can be evaluated in terms of their components, with the
'Pos,
'Val, 'Pred, and 'Succ attributes all being properly handled. This
package
can be employed in the calculation of array bounds, range constraints,
and
wherever an expression is used whose value can be calculated solely
through
semantic analysis.
