◆ GetDebugInfoIndexWasLoadedFromCache()

bool SymbolFileDWARFDwo::GetDebugInfoIndexWasLoadedFromCache ( ) const

overridevirtual

Accessors for the bool that indicates if the debug info index was loaded from, or saved to the module index cache.

In statistics it is handy to know if a module's debug info was loaded from or saved to the cache. When the debug info index is loaded from the cache startup times can be faster. When the cache is enabled and the debug info index is saved to the cache, debug sessions can be slower. These accessors can be accessed by the statistics and emitted to help track these costs.

◆ GetDebugInfoSize()

uint64_t SymbolFileDWARFDwo::GetDebugInfoSize ( bool load_all_debug_info = false )

overridevirtual

Metrics gathering functions.

Return the size in bytes of all loaded debug information or total possible debug info in the symbol file.

If the debug information is contained in sections of an ObjectFile, then this call should add the size of all sections that contain debug information. Symbols the symbol tables are not considered debug information for this call to make it easy and quick for this number to be calculated. If the symbol file is all debug information, the size of the entire file should be returned. The default implementation of this function will iterate over all sections in a module and add up their debug info only section byte sizes.

Parameters

load_all_debug_info If true, force loading any symbol files if they are not yet loaded and add to the total size. Default to false.

Returns: Total currently loaded debug info size in bytes

◆ GetDIERefSymbolFile()

SymbolFileDWARF * SymbolFileDWARFDwo::GetDIERefSymbolFile ( const DIERef & die_ref )

overridevirtual

Given a DIERef, find the correct SymbolFileDWARF.

A DIERef contains a file index that can uniquely identify a N_OSO file for DWARF in .o files on mac, or a .dwo or .dwp file index for split DWARF. Calling this function will find the correct symbol file to use so that further lookups can be done on the correct symbol file so that the DIE offset makes sense in the DIERef.
