Nowhere in the code we call set Ekind to E_Protected_Object, so all the
code that tests this is necessarily dead. This patch removes references
to E_Protected_Object.
Tested on x86_64-pc-linux-gnu, committed on trunk
gcc/ada/
* einfo.ads (E_Protected_Object): Enumeration literal removed.
* lib-xref.ads (Xref_Entity_Letters): Remove reference to
removed literal.
* sem_ch3.adb (Check_Completion): Likewise.
* sem_util.adb (Has_Enabled_Property): Likewise.diff --git a/gcc/ada/einfo.ads b/gcc/ada/einfo.ads
