At AdaCore, we run the internal gdb test suite in several modes, including one using the .debug_names index. This caught a regression caused by the new DWARF indexer. First, the psymtabs-based .debug_names generator was completely wrong. However, to avoid making the rewrite series even bigger (fixing the writer will also require rewriting the .debug_names reader), it attempted to preserve the weirdness. However, this was not done properly. For example the old writer did this: - case STRUCT_DOMAIN: - return DW_TAG_structure_type; The new code, instead, simply preserves the actual DWARF tag -- but this makes future lookups fail, because the .debug_names reader only looks for DW_TAG_structure_type. This patch attempts to revert to the old behavior in the writer.
