From: Eric Botcazou <ebotcazou@adacore.com> Many aspects are (correctly) marked as GNAT-specific but nevertheless not listed in the Implementation_Defined_Aspect array, so this aligns the two sides and also removes Default_Initial_Condition and Object_Size from the list, since they are defined in Ada 2022. This also moves No_Controlled_Parts and No_Task_Parts to the subclass of boolean aspects, and completes the list of nonoverridable aspects defined in Ada 2022. gcc/ada/ * aspects.ads (Aspect_Id): Alphabetize, remove the GNAT tag from Default_Initial_Condition and Object_Size, move No_Controlled_Parts and No_Task_Parts to boolean subclass. (Nonoverridable_Aspect_Id): Add missing Ada 2022 aspects. (Implementation_Defined_Aspect): Add all missing aspects, remove Max_Entry_Queue_Length and Object_Size (Aspect_Argument): Remove specific entries for No_Controlled_Parts and No_Task_Parts, list boolean aspects last. (Is_Representation_Aspect ): Move boolean aspects last. (Aspect_Names): Alphabetize. * sem_ch13.adb (Analyze_Aspect_Disable_Controlled): Adjust. (Analyze_Aspect_Specifications): Move around processing for No_Controlled_Parts and No_Task_Parts. (Check_Aspect_At_Freeze_Point): Remove specific entries for No_Controlled_Parts and No_Task_Parts Tested on x86_64-pc-linux-gnu, committed on master. --- gcc/ada/aspects.ads | 94 ++++++++++++++++++++++++++++---------------- gcc/ada/sem_ch13.adb | 69 +++++++++++++++++++------------- 2 files changed, 101 insertions(+), 62 deletions(-)
