getOrCreateModuleInfo()

Expected< SymbolizableModule * > llvm::symbolize::LLVMSymbolizer::getOrCreateModuleInfo

(

ModuleName

)

Returns a SymbolizableModule or an error if loading debug info failed.

Only one attempt is made to load a module, and errors during loading are only reported once. Subsequent calls to get module info for a module that failed to load will return nullptr.
