...n wrong about what’s going on. (That being said, I could lose myself in the LLVM code base for a long time if I let myself; it’s already taught me more about compiler design and even the C++ language than my entire career up to now!) To give some detail, the code paths I saw were DWARFCompileUnit::getNumDIEs(), which parses all DIEs via the extractDIEsToVector() path, and DWARFCompileUnit::extract(), which parses just one specified DIE via the extractImpl() path. It’s not obvious to me why the extractImpl() code exists alongside DWARFDebugInfoEntryMinimal::extractFast(). In general, the "extract...
