Detailed Description

Symbol from .dynsym combined with additional information.

The additional information is:

• The symbol's entry in the GNU Symbol Version Table (.gnu.version section)
• The symbol's entry in the GNU Symbol Version Definition Table (.gnu.version_d section), if any.
• The symbol's auxiliary information (and thus, indirectly, the table entry) from the GNU Symbol Version Requirements Table (.gnu.version_r section), if any.

Member Function Documentation

bool BinaryLoaderElf::VersionedSymbol::is_local

(

)

const

Returns true if this symbol is visible only locally.

bool BinaryLoaderElf::VersionedSymbol::is_hidden

(

)

const

Returns true if this symbol is hidden.

bool BinaryLoaderElf::VersionedSymbol::is_reference

(

)

const

Returns true if this symbol is a reference to an object rather than the definition of the object.

bool BinaryLoaderElf::VersionedSymbol::is_base_definition

(

)

const

Returns tru if this symbol is a base definition.

A base definition is either an unversioned symbol or a version definition with the VER_FLG_BASE flag set.

void BinaryLoaderElf::VersionedSymbol::set_symbol ( SgAsmElfSymbol *  symbol)

inline

(Re)initializes this symbol.

std::string BinaryLoaderElf::VersionedSymbol::get_version

(

)

const

Returns the version string of this symbol.

The empty string is returned if the symbol has no associated version.

std::string BinaryLoaderElf::VersionedSymbol::get_name ( ) const

inline

Returns the name of this symbol.

std::string BinaryLoaderElf::VersionedSymbol::get_versioned_name

(

)

const

Returns the full, versionioned name of this symbol.

Used for debugging.

void BinaryLoaderElf::VersionedSymbol::set_version_entry ( SgAsmElfSymverEntry *  entry)

inline

Set the version pointer for this symbol.

Definition at line 115 of file BinaryLoaderElf.h.

References p_version_entry.

void BinaryLoaderElf::VersionedSymbol::set_version_def ( SgAsmElfSymverDefinedEntry *  def)

inline

Set the version definition of this symbol.

The definition flags must be zero or VER_FLG_BASE.

Definition at line 120 of file BinaryLoaderElf.h.

References SgAsmElfSymverDefinedEntry::get_flags(), p_version_def, and BinaryLoaderElf::VER_FLG_BASE.

void BinaryLoaderElf::VersionedSymbol::set_version_need ( SgAsmElfSymverNeededAux *  need)

inline

Set the version requirement of this symbol.

The requirement flags must be zero or VER_FLG_WEAK.

Definition at line 126 of file BinaryLoaderElf.h.

References SgAsmElfSymverNeededAux::get_flags(), p_version_need, and BinaryLoaderElf::VER_FLG_WEAK.

SgAsmElfSymverNeededAux* BinaryLoaderElf::VersionedSymbol::get_version_need ( ) const

inline

Get the version requirement of this symbol.

Definition at line 132 of file BinaryLoaderElf.h.

References p_version_need.

SgAsmElfSymverDefinedEntry* BinaryLoaderElf::VersionedSymbol::get_version_def ( ) const

inline

Get the version definition of this symbol.
