From: Viljar Indus <in...@adacore.com> When the Extend_System pragma is used then we are supposed to check the extended system for referenced entities. Otherwise we would get an incorrect unused with warning.
This was previously done on body files but it should also be done specs as well. gcc/ada/ChangeLog: * sem_warn.adb (Check_One_Unit): When a system extension is present always check entities from that unit before marking the unit unreferenced. Tested on x86_64-pc-linux-gnu, committed on master. --- gcc/ada/sem_warn.adb | 11 +++++++---- 1 file changed, 7 insertions(+), 4 deletions(-) diff --git a/gcc/ada/sem_warn.adb b/gcc/ada/sem_warn.adb index 69e60be2966..2ffd631d628 100644 --- a/gcc/ada/sem_warn.adb +++ b/gcc/ada/sem_warn.adb @@ -2583,14 +2583,17 @@ package body Sem_Warn is if No (Ent) then + -- Check entities in the extended system if + -- specified. + + if Check_System_Aux (Lunit) then + null; + -- If in spec, just set the flag - if Unit = Spec_Unit then + elsif Unit = Spec_Unit then Set_No_Entities_Ref_In_Spec (Item); - elsif Check_System_Aux (Lunit) then - null; - -- Else the warning may be needed else -- 2.43.0
