-- individually to yield the required Boolean result. Loc is the
-- location for the generated nodes. Typ is the type of the record, and
-- Lhs, Rhs are the record expressions to be compared, these
-- expressions need not to be analyzed but have to be side-effect free.
-- Bodies is a list on which to attach bodies of local functions that
-- are created in the process. This is the responsibility of the caller
-- to insert those bodies at the right place. Nod provides the Sloc
-- value for generated code.

-- Returns true if the node is a type conversion whose operand is an

-- signed integer type is smaller than Standard.Integer. In such case we
-- have special circuitry in Expand_N_Type_Conversion to promote both of
-- the operands to type Integer.
