Member Typedef Documentation
◆ global_scope_sptr
| typedef shared_ptr<scope_decl> global_scope_sptr |

◆ translation_unit()
| translation_unit | ( | const ir::environment & | env, |
| const std::string & | path, | ||
| char | address_size = 0 |
||
| ) |
Constructor of translation_unit.
- Parameters
-
env the environment of this translation unit. Please note that the life time of the environment must be greater than the life time of the translation unit because the translation uses resources that are allocated in the environment. path the location of the translation unit. address_size the size of addresses in the translation unit, in bits.

◆ bind_function_type_life_time()
| void bind_function_type_life_time | ( | function_type_sptr | ftype | ) | const |
Ensure that the life time of a function type is bound to the life time of the current translation unit.
- Parameters
-
ftype the function time which life time to bind to the life time of the current instance of translation_unit. That is, it's onlyh when the translation unit is destroyed that the function type can be destroyed to.
◆ get_absolute_path()
| const std::string & get_absolute_path | ( | ) | const |
◆ get_address_size()
| char get_address_size | ( | ) | const |
◆ get_compilation_dir_path()
| const std::string & get_compilation_dir_path | ( | ) | const |
Get the path of the directory that was 'current' when the translation unit was compiled.
Note that the path returned by translation_unit::get_path is relative to the path returned by this function.
- Returns
- the compilation directory for the current translation unit.

◆ get_corpus() [2/2]
| const corpus * get_corpus | ( | ) | const |
◆ get_environment()

Getter of the environment of the current translation_unit.

◆ get_loc_mgr() [2/2]
| const location_manager & get_loc_mgr | ( | ) | const |
◆ get_path()
| const std::string & get_path | ( | ) | const |
Get the path of the current translation unit.
This path is relative to the build directory of the translation unit as returned by translation_unit::get_compilation_dir_path.
- Returns
- the relative path of the compilation unit associated to the current instance of translation_unit.
◆ get_types() [1/2]
| type_maps & get_types | ( | ) |
Getter of the types of the current translation_unit.
- Returns
- the maps of the types of the translation unit.
◆ get_types() [2/2]
| const type_maps & get_types | ( | ) | const |
Getter of the types of the current translation_unit.
- Returns
- the maps of the types of the translation unit.
◆ is_constructed()
| bool is_constructed | ( | ) | const |
Getter of the 'is_constructed" flag. It says if the translation unit is fully constructed or not.
This flag is important for cases when comparison might depend on if the translation unit is fully built or not. For instance, when reading types from DWARF, the virtual methods of a class are not necessarily fully constructed until we have reached the end of the translation unit. In that case, before we've reached the end of the translation unit, we might not take virtual functions into account when comparing classes.
- Returns
- true if the translation unit is constructed.
◆ is_empty()
| bool is_empty | ( | ) | const |
◆ operator!=()
| bool operator!= | ( | const translation_unit & | o | ) | const |
Inequality operator.
- Parameters
-
o the instance of translation_unit to compare the current instance against.
- Returns
- true iff the current instance is different from
o.
◆ operator==()
| bool operator== | ( | const translation_unit & | other | ) | const |
◆ set_address_size()
| void set_address_size | ( | char | a | ) |
◆ set_compilation_dir_path()
| void set_compilation_dir_path | ( | const std::string & | d | ) |
Set the path of the directory that was 'current' when the translation unit was compiled.
Note that the path returned by translation_unit::get_path is relative to the path returned by this function.
- Parameters
-
the compilation directory for the current translation unit.
◆ set_corpus()
| void set_corpus | ( | corpus * | c | ) |
◆ set_is_constructed()
| void set_is_constructed | ( | bool | f | ) |
Setter of the 'is_constructed" flag. It says if the translation unit is fully constructed or not.
This flag is important for cases when comparison might depend on if the translation unit is fully built or not. For instance, when reading types from DWARF, the virtual methods of a class are not necessarily fully constructed until we have reached the end of the translation unit. In that case, before we've reached the end of the translation unit, we might not take virtual functions into account when comparing classes.
- Parameters
-
f true if the translation unit is constructed.
◆ set_language()
| void set_language | ( | language | l | ) |
◆ set_path()
| void set_path | ( | const string & | a_path | ) |
Set the path associated to the current instance of translation_unit.
This path is relative to the build directory of the translation unit as returned by translation_unit::get_compilation_dir_path.
- Parameters
-
a_path the new relative path to set.
◆ traverse()
|
virtual |
This implements the ir_traversable_base::traverse virtual function.

Friends And Related Function Documentation
◆ synthesize_function_type_from_translation_unit
|
friend |
In a translation unit, lookup the sub-types that make up a given function type and if the sub-types are all found, synthesize and return a function_type with them.
This function is like lookup_function_type_in_translation_unit() execept that it constructs the function type from the sub-types found in the translation, rather than just looking for the function types held by the translation unit. This can be useful if the translation unit doesnt hold the function type we are looking for (i.e, lookup_function_type_in_translation_unit() returned NULL) but we still want to see if the sub-types of the function types are present in the translation unit.
- Parameters
-
fn_type the function type to consider. tu the translation unit to look into.
- Returns
- the resulting synthesized function type if all its sub-types have been found, NULL otherwise.
◆ synthesize_type_from_translation_unit
|
friend |
In a translation unit, lookup a given type or synthesize it if it's a qualified type.
So this function first looks the type up in the translation unit. If it's found, then OK, it's returned. Otherwise, if it's a qualified, reference or pointer or function type (a composite type), lookup the underlying type, synthesize the type we want from it and return it.
If the underlying types is not not found, then give up and return nil.
- Returns
- the type that was found or the synthesized type.
