Function Documentation

◆ finalize_linking()

void finalize_linking	(	goto_modelt &	dest,
		const replace_symbolt::expr_mapt &	type_updates
	)

Apply type_updates to dest, where type_updates were constructed from one or more calls to link_goto_model.

◆ link_functions()

static bool link_functions	(	symbol_tablet &	dest_symbol_table,
		goto_functionst &	dest_functions,
		const symbol_tablet &	src_symbol_table,
		goto_functionst &	src_functions,
		const rename_symbolt &	rename_symbol,
		const std::unordered_set< irep_idt > &	weak_symbols
	)

static

Link a set of goto functions, considering weak symbols and symbol renaming.

◆ link_goto_model()

optionalt<replace_symbolt::expr_mapt> link_goto_model	(	goto_modelt &	dest,
		goto_modelt &&	src,
		message_handlert &
	)

Link goto model src into goto model dest, invalidating src in this process.

Linking may require updates to object types contained in dest, which need to be applied using finalize_linking.

Returns: nullopt if linking fails, else a (possibly empty) collection of replacements to be applied.

		irep_idt &	new_function_name,
		const rename_symbolt &	rename_symbol
