- -- Aspect_Cancel (Flag11-Sem)
- -- Processing of aspect specifications typically generates pragmas and
- -- attribute definition clauses that are inserted into the tree after
- -- the declaration node to get the desired aspect effect. In the case
- -- of Boolean aspects that use "=> False" to cancel the effect of an
- -- aspect (i.e. turn if off), the generated pragma has the Aspect_Cancel
- -- flag set to indicate that the pragma operates in the opposite sense.
