sem_prag.adb (Analyze pragma, [...]): Analyze argument of pragma, to capture global references if the context is generic.
2009-07-10 Ed Schonberg <schonberg@adacore.com>
* sem_prag.adb (Analyze pragma, case Task_Name): Analyze argument of
pragma, to capture global references if the context is generic.
* exp_ch2.adb (Expand_Discriminant): If a task type discriminant
appears within the initialization procedure for the corresponding
record, replace it with the proper discriminal.
