----------------
Generally we remove all the unnecessary attributes, rather than just take the raw -emit-llvm output.


================
Comment at: test/DebugInfo/Generic/static-const-fp.ll:78
+; CHECK: DW_TAG_variable
+; CHECK-NOT: {{^0}}
+; CHECK: DW_AT_name {{.*}} "hVal"
----------------
To verify that the next attribute is part of the same DIE we usually do:
```
CHECK-NOT: {{DW_TAG|NULL}}
```
which shows it's not in a child and not in a DIE from a higher nesting level.
