| -- arguments has been checked, as well as possible optional identifiers, |
| -- but no other checks have been made. This subprogram completes the |
| -- checking, and then if the pragma is well formed, makes appropriate |
| -- entries in the internal tables used to keep track of Eliminate pragmas. |
| -- The other five arguments are expressions (rather than pragma argument |
| -- associations) for the possible pragma arguments. A parameter that |
| -- is not present is set to Empty. |

| -- Check that the subprogram S (or its ultimate parent in the case of a |
| -- derived subprogram or renaming) has not been eliminated. An error will |
| -- be flagged if the subprogram has been eliminated, unless the node N |
| -- occurs within an eliminated subprogram or within a generic unit. The |
