generic type Integer_Type is range <>; package Generic_Bit_Operations is -- Operations on an integer type as an array of bits. -- Bit numbering is left to right, starting from 0. -- Arguments specified outside bit range raise Constraint_Error -- Note :- The CDFs may allocate 32 bits for integer subtypes. -- For eg: integer range -128..127 may result in the -- allocation of a 32 bit integer. Hence integer_type'size -- must not be relied upon when using this pacakge . -- However this package will compute the offset of Bit 0 -- for any type properly. -- Extract the bits from Start .. Start + Length - 1.
