[gcc.git] / gcc / ada / ChangeLog

2017-01-12  Arnaud Charlet  <charlet@adacore.com>

        * gcc-interface/Makefile.in: Clean up VxWorks targets.

2017-01-12  Ed Schonberg  <schonberg@adacore.com>

        * sem_attr.adb (Analyze_Attribute_Reference, case Loop_Entry):
        Hnadle properly the attribute reference when it appears as part
        of an expression in another loop aspect.

2017-01-12  Ed Schonberg  <schonberg@adacore.com>

        * exp_ch3.adb (Check_Predicated_Discriminant): New procedure,
        subsidiary of Build_Initialization_Call, to complete generation
        of predicate checks on discriminants whose (sub)types have
        predicates, and to add checks on variants that do not have an
        others clause.
        * sem_util.adb (Gather_Components): A missing Others alternative is
        not an error when the type of the discriminant is a static predicate
        (and coverage has been checked when analyzing the case statement). A
        runtime check is generated to verify that a given discriminant
        satisfies the predicate (RM 3.8.1. (21.1/2)).

        flag is not falsly set.
        * sem_ch3.adb (Make_Class_Wide_Type): Initialize copy of class
        wide type to have no invariant flags.
