llvm-project/llvm/tools/llvm-pdbutil/DumpOutputStyle.cpp
Reid Kleckner 14d90fd05c [PDB] Improve GSI hash table dumping for publics and globals 
The PDB "symbol stream" actually contains symbol records for the publics
and the globals stream. The globals and publics streams are essentially
hash tables that point into a single stream of records. In order to
match cvdump's behavior, we need to only dump symbol records referenced
from the hash table. This patch implements that, and then implements
global stream dumping, since it's just a subset of public stream
dumping.

Now we shouldn't see S_PROCREF or S_GDATA32 records when dumping
publics, and instead we should see those record in the globals stream.
