When using cross-reference information to get subprogram effects in
SPARK (i.e. its reads and writes), we were calling Renamed_Object on
enumeration literals. This was pointless but harmless; now it rightly
triggers an assertion failure in developer builds, so avoid that.
Tested on x86_64-pc-linux-gnu, committed on trunk
gcc/ada/
* lib-xref.adb (Get_Through_Renamings): Exit loop when an
enumeration literal is found.
