| -- |
| -- OBJECTIVE: |
| -- Check that if a discriminant constraint depends on a discriminant, |
| -- the evaluation of the expressions in the constraint is deferred until |
| -- an object of the subtype is created. Check for cases of records. |
| -- |
| -- TEST DESCRIPTION: |
| -- This transition test defines record types with discriminant components |
| -- which depend on the discriminants. The discriminants are calculated |
| -- by function calls. The test verifies that Constraint_Error is raised |
| -- during the object creations when values of discriminants are |
| -- incompatible with the subtypes. |
| -- |
| -- Inspired by C37213A.ADA, C37213C.ADA, C37215A.ADA and C37215C.ADA. |
