<pre>When compiling clangd with clang it generates the following debug info:
Abbrev Number: 166 (DW_TAG_unspecified_type)
DW_AT_name : (indexed string: 0xb0c6): auto
This is not handled in DWARFASTParserClang::ParseTypeModifier:
case DW_TAG_unspecified_type:
if (attrs.name == "nullptr_t" || attrs.name == "decltype(nullptr)") {
resolve_state = Type::ResolveState::Full;
clang_type = m_ast.GetBasicType(eBasicTypeNullPtr);
break;
}
// Fall through to base type below in case we can handle the type
// there...
LLVM_FALLTHROUGH;
case DW_TAG_base_type:
And due to the fallthrough this results in the following (somewhat misleading)
error message:
error: need to add support for DW_TAG_base_type 'auto' encoded with DW_ATE =
0x0, bit_size = 0</pre>
