Function Documentation

◆ create_default_fn_sym()

elf_symbol_sptr abigail::dwarf::create_default_fn_sym	(	const string &	sym_name,
		const environment &	env
	)

Create a function symbol with a given name.

Parameters

sym_name	the name of the symbol to create.
env	the environment to create the symbol in.

Returns: the newly created symbol.

Definition at line 15432 of file abg-dwarf-reader.cc.

◆ create_reader()

elf_based_reader_sptr create_reader	(	const std::string &	elf_path,
		const vector< char ** > &	debug_info_root_paths,
		environment &	environment,
		bool	load_all_types,
		bool	linux_kernel_mode
	)

Create a dwarf::reader.

Parameters

elf_path	the path to the elf file the reader is to be used for.
debug_info_root_paths	a vector to the paths to the directories under which the debug info is to be found for `elf_path`. Pass an empty vector if the debug info is not in a split file.
environment	the environment used by the current context. This environment contains resources needed by the DWARF reader and by the types and declarations that are to be created later. Note that ABI artifacts that are to be compared all need to be created within the same environment.

Please also note that the life time of this environment object must be greater than the life time of the resulting reader the context uses resources that are allocated in the environment.

Parameters

load_all_types	if set to false only the types that are reachable from publicly exported declarations (of functions and variables) are read. If set to true then all types found in the debug information are loaded.
linux_kernel_mode	if set to true, then consider the special linux kernel symbol tables when determining if a symbol is exported or not.

Returns: a smart pointer to the resulting dwarf::reader.

Definition at line 16446 of file abg-dwarf-reader.cc.

◆ is_anonymous_type_die()

bool abigail::dwarf::is_anonymous_type_die ( Dwarf_Die * die )

Test if a given DIE represents an anonymous type.

Anonymous types we are interested in are classes, unions and enumerations.

Parameters

die	the DIE to consider.

Returns: true iff die represents an anonymous type.

Definition at line 9173 of file abg-dwarf-reader.cc.

◆ lookup_public_function_symbol_from_elf()

bool abigail::dwarf::lookup_public_function_symbol_from_elf	(	environment &	env,
		const string &	path,
		const string &	symname,
		vector< elf_symbol_sptr > &	syms
	)

Look into the symbol tables of an elf file to see if a public function of a given name is found.

Parameters

env	the environment we are operating from.
elf_path	the path to the elf file to consider.
symbol_name	the name of the function to look for.
syms	the vector of public function symbols found with the name `symname`.

Returns: true iff a function with symbol name symbol_name is found.

Definition at line 16616 of file abg-dwarf-reader.cc.

◆ lookup_symbol_from_elf()

bool lookup_symbol_from_elf	(	const environment &	env,
		const string &	elf_path,
		const string &	symbol_name,
		bool	demangle,
		vector< elf_symbol_sptr > &	syms
	)

Look into the symbol tables of a given elf file and see if we find a given symbol.

Parameters

env	the environment we are operating from.
elf_path	the path to the elf file to consider.
symbol_name	the name of the symbol to look for.
demangle	if true, try to demangle the symbol name found in the symbol table.
syms	the vector of symbols found with the name `symbol_name`.

Returns: true iff the symbol was found among the publicly exported symbols of the ELF file.

Definition at line 16571 of file abg-dwarf-reader.cc.

◆ read_corpus_from_elf()

corpus_sptr read_corpus_from_elf	(	const std::string &	elf_path,
		const vector< char ** > &	debug_info_root_paths,
		environment &	environment,
		bool	load_all_types,
		fe_iface::status &	status
	)

Read all abigail::translation_unit possible from the debug info accessible from an elf file, stuff them into a libabigail ABI Corpus and return it.

Parameters

elf_path	the path to the elf file.
debug_info_root_paths	a vector of pointers to root paths under which to look for the debug info of the elf files that are later handled by the Dwfl. This for cases where the debug info is split into a different file from the binary we want to inspect. On Red Hat compatible systems, this root path is usually /usr/lib/debug by default. If this argument is set to NULL, then "./debug" and /usr/lib/debug will be searched for sub-directories containing the debug info file.
environment	the environment used by the current context. This environment contains resources needed by the DWARF reader and by the types and declarations that are to be created later. Note that ABI artifacts that are to be compared all need to be created within the same environment. Also, the lifetime of the environment must be greater than the lifetime of the resulting corpus because the corpus uses resources that are allocated in the environment.
load_all_types	if set to false only the types that are reachable from publicly exported declarations (of functions and variables) are read. If set to true then all types found in the debug information are loaded.
resulting_corp	a pointer to the resulting abigail::corpus.

Returns: the resulting status.

Definition at line 16540 of file abg-dwarf-reader.cc.

◆ reset_reader()

void reset_reader	(	elf_based_reader &	rdr,
		const std::string &	elf_path,
		const vector< char ** > &	debug_info_root_path,
		bool	read_all_types,
		bool	linux_kernel_mode
	)

Re-initialize a reader so that it can re-used to read another binary.

Parameters

rdr	the context to re-initialize.
elf_path	the path to the elf file the context is to be used for.
debug_info_root_path	a pointer to the path to the root directory under which the debug info is to be found for `elf_path`. Leave this to NULL if the debug info is not in a split file.
environment	the environment used by the current context. This environment contains resources needed by the DWARF reader and by the types and declarations that are to be created later. Note that ABI artifacts that are to be compared all need to be created within the same environment.

Please also note that the life time of this environment object must be greater than the life time of the resulting reader the context uses resources that are allocated in the environment.

Parameters

load_all_types	if set to false only the types that are reachable from publicly exported declarations (of functions and variables) are read. If set to true then all types found in the debug information are loaded.
linux_kernel_mode	if set to true, then consider the special linux kernel symbol tables when determining if a symbol is exported or not.

Returns: a smart pointer to the resulting dwarf::reader.
