class SymbolContext

Defined at line 19 of file ../../src/developer/debug/zxdb/symbols/symbol_context.h

Addresses in symbols are interpreted in terms of relative offsets from the beginning of the

module. When a module is loaded into memory, it has a physical address, and all symbol addresses

need to be offset to convert back and forth between physical and symbolic addresses.

This class holds the load information for converting between these two address types.

Public Methods

AddressRange RelativeToAbsolute (const AddressRange & relative)

AddressRange conversion.

AddressRange AbsoluteToRelative (const AddressRange & absolute)

Defined at line 13 of file ../../src/developer/debug/zxdb/symbols/symbol_context.cc

AddressRanges RelativeToAbsolute (const AddressRanges & relative)

AddressRanges conversion.

SymbolContext ForRelativeAddresses ()

Creates a symbol context has no offset. Using it will return addresses relative to the module.

This can be useful for testing and for resolving which symbols might be available even when no

program is running.

bool is_relative ()

Returns true if this is a relative symbol context. Relative contexts do not have a real

loaded module associated with them and addresses will be unchanged between relative and

absolute.
