+ -- This line records information from a Priority_Specific_Dispatching

+
+ -- The policy_identifier is the first character (upper case) of the

+
+ -- The first_priority and last_priority fields define the range of

-- The <<attributes>> are a series of two letter codes indicating
-- information about the unit:
--
+ -- BD Unit does not have pragma Elaborate_Body, but the elaboration
+ -- circuit has determined that it would be a good idea if this
+ -- pragma were present, since the body of the package contains
+ -- elaboration code that modifies one or more variables in the
+ -- visible part of the package. The binder will try, but does
+ -- not promise, to keep the elaboration of the body close to
+ -- the elaboration of the spec.
+ --
-- DE Dynamic Elaboration. This unit was compiled with the
-- dynamic elaboration model, as set by either the -gnatE
-- switch or pragma Elaboration_Checks (Dynamic).
-- Following each U line, is a series of lines of the form
- -- W unit-name [source-name lib-name] [E] [EA] [ED]
+ -- W unit-name [source-name lib-name] [E] [EA] [ED] [AD]
--
-- One of these lines is present for each unit that is mentioned in
-- an explicit with clause by the current unit. The first parameter
--
-- EA pragma Elaborate_All applies to this unit
--
- -- ED Elaborate_All_Desirable set for this unit, which means
+ -- ED Elaborate_Desirable set for this unit, which means
+ -- that there is no Elaborate, but the analysis suggests
+ -- that Program_Error may be raised if the Elaborate
+ -- conditions cannot be satisfied. The binder will attempt
+ -- to treat ED as E if it can.
+ --
+ -- AD Elaborate_All_Desirable set for this unit, which means
-- that there is no Elaborate_All, but the analysis suggests
-- that Program_Error may be raised if the Elaborate_All
-- conditions cannot be satisfied. The binder will attempt
- -- to treat ED as EA if it can.
+ -- to treat AD as EA if it can.
