Detailed Description

SymbolFileOnDemand wraps an actual SymbolFile by providing on demand symbol parsing/indexing to improve performance.

By default SymbolFileOnDemand will skip load the underlying symbols. Any client can on demand hydrate the underlying SymbolFile via SymbolFile::SetLoadDebugInfoEnabled().

◆ GetAbilities()

uint32_t SymbolFileOnDemand::GetAbilities ( )

overridevirtual

Get a mask of what this symbol file supports for the object file that it was constructed with.

Each symbol file gets to respond with a mask of abilities that it supports for each object file. This happens when we are trying to figure out which symbol file plug-in will get used for a given object file. The plug-in that responds with the best mix of "SymbolFile::Abilities" bits set, will get chosen to be the symbol file parser. This allows each plug-in to check for sections that contain data a symbol file plug-in would need. For example the DWARF plug-in requires DWARF sections in a file that contain debug information. If the DWARF plug-in doesn't find these sections, it won't respond with many ability bits set, and we will probably fall back to the symbol table SymbolFile plug-in which uses any information in the symbol table. Also, plug-ins might check for some specific symbols in a symbol table in the case where the symbol table contains debug information (STABS and COFF). Not a lot of work should happen in these functions as the plug-in might not get selected due to another plug-in having more abilities. Any initialization work should be saved for "void SymbolFile::InitializeObject()" which will get called on the SymbolFile object with the best set of abilities.

Returns: A uint32_t mask containing bits from the SymbolFile::Abilities enumeration. Any bits that are set represent an ability that this symbol plug-in can parse from the object file.

◆ GetDebugInfoIndexTime()

◆ GetDebugInfoIndexWasLoadedFromCache()

bool lldb_private::SymbolFileOnDemand::GetDebugInfoIndexWasLoadedFromCache ( ) const

inlineoverridevirtual

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.

Return the time taken to parse the debug information.

◆ GetDebugInfoSize()

uint64_t SymbolFileOnDemand::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
