Member Function Documentation

VersionedSymbol BinaryLoaderElf::SymverResolver::get_versioned_symbol

(

SgAsmElfSymbol *

symbol)

const

Returns the VersionedSymbol corresponding to the specified symbol.

The specified symbol must be a member of the versioned symbol map (or an assertion fails).

void BinaryLoaderElf::SymverResolver::dump	(	FILE *	,
		const char *	prefix,
		ssize_t	idx
	)		const

Print some info about the resolver.

void BinaryLoaderElf::SymverResolver::ctor ( SgAsmGenericHeader *  )

private

Helper for constructors.

Referenced by SymverResolver().

void BinaryLoaderElf::SymverResolver::makeSymbolVersionDefMap ( SgAsmElfSymverDefinedSection *  )

private

Initialize the p_symbolVersionDefMap from the ELF Symbol Version Definition Table.

This mapping is from each entry's get_index() to the entry itself.

void BinaryLoaderElf::SymverResolver::makeSymbolVersionNeedMap ( SgAsmElfSymverNeededSection *  )

private

Initialize the p_symbolVersionNeedMap from the ELF Symbol Version Requirements Table auxiliary information.

The mapping is from each auxiliary's get_other() to the auxiliary. The table entries are available indirectly since an SgAsmElfSymverNeededEntry is the parent of each SgAsmElfSymverNeededAux.

void BinaryLoaderElf::SymverResolver::makeVersionedSymbolMap ( SgAsmElfSymbolSection *  , SgAsmElfSymverSection *    )

private

Create a map from from each SgAsmElfSymbol* to a VersionedSymbol.

The p_symbolVersionDefMap must be initialized before calling this. The SgAsmElfSymverSection argument may be null, in which case VersionedSymbols are basically just a wrapper to their SgAsmElfSymbol.

Member Data Documentation

SymbolVersionDefinitionMap BinaryLoaderElf::SymverResolver::p_symbolVersionDefMap

private

Map from each ELF Symbol Version Definition Table entry's get_index() to the entry itself.

Definition at line 243 of file BinaryLoaderElf.h.

SymbolVersionNeededMap BinaryLoaderElf::SymverResolver::p_symbolVersionNeedMap

private

Map from each auxiliary's get_other() to the auxiliary itself.

The auxiliaries come from the GNU Symbol Version Requirements Table, each entry of which points to a list of auxiliaries. The parent of each auxiliary is the table entry that contained the auxiliary, thus this mapping also maps get_other() to GNU Symbol Version Requirements Table entries.

VersionedSymbolMap BinaryLoaderElf::SymverResolver::p_versionedSymbolMap

private

Map from an SgAsmElfSymbol to a VersionedSymbol.
