* sem_ch3.adb (Process_Subtype): An allocator is a valid construct that can carry a null exclusion indicator, and on which an error may be posted if the indicator is redundant. * sem_ch8.adb (Analyze_Object_Renaming): Verify that a null exclusion does not apply to a subtype mark that already excludes null. * sem_ch12.adb (Formal_Object_Declaration): Verify that a null exclusion does not apply to a subtype mark that already excludes null. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@138728 138bc75d-0d04-0410-961f-82ee72b054a4
