Implementation of DWARF expression parser
...re 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" paradigm is difficult to get a handle on, and I’ve yet to find any documentation. Another example is the DWARFContext::getCompileUnitForAddress()...
