...- extend DINamespace with an extra UniqueID filed (analogous to DICompositeType) - add an extra case to DIScope::getRef() - Let CGDebugInfo create a mangled name for each namespace to use as UID -> the UID of the anonymous namespace is null. For example: namespace a { namespace b {} } -> “_ZN1a", “_ZN1a1b" !0 = [compile unit] !1 = metadata !{i32 786489, metadata !0, metadata !”_ZN1a", metadata !”b", i32 1, metadata !”_ZN1a1b"} ; [ DW_TAG_namespace ] [a] !2 = metadata !{i32 786489, metadata !0, null, metadata !”a", i32 1, metadata !”_ZN1a"} ; [ DW_TAG_na...
