Rule SPARK RM 6.1.4(13) only mentions "subprograms", but it is equally
applicable to protected entries whose global inputs cannot appear as
global outputs in nested subprograms.
Tested on x86_64-pc-linux-gnu, committed on trunk
gcc/ada/
* sem_prag.adb (Check_Mode_Restriction_In_Enclosing_Context):
Extend check to protected entries.
