Detailed Description

The internal representation of an integral type.

This is a "utility type" used internally to canonicalize the name of fundamental integral types, so that "unsignd long" and "long unsined int" end-up having the same name.

Member Enumeration Documentation

base_type

enum base_type

The possible base types of integral types. We might have forgotten many of these, so do not hesitate to add new ones.

If you do add new ones, please also consider updating functions parse_base_real_type and real_type::to_string.

Enumerator
INT_BASE_TYPE	The "int" base type.
CHAR_BASE_TYPE	The "char" base type.
BOOL_BASE_TYPE	The "bool" base type in C++ or "_Bool" in C11.
DOUBLE_BASE_TYPE	The "double" base type.
FLOAT_BASE_TYPE	The "float" base type.
CHAR16_T_BASE_TYPE	The "char16_t base type.
CHAR32_T_BASE_TYPE	The "char32_t" base type.
WCHAR_T_BASE_TYPE	The "wchar_t" base type.
ARRAY_SIZE_BASE_TYPE	The aray size type used by Clang.

Definition at line 55 of file abg-ir-priv.h.

modifiers_type

enum modifiers_type

The modifiers of the base types above. Several modifiers can be combined for a given base type. The presence of modifiers is usually modelled by a bitmap of modifiers.

If you add a new modifier, please consider updating functions parse_real_type_modifier and real_type::to_string.

Enumerator
SIGNED_MODIFIER	The "signed" modifier.
UNSIGNED_MODIFIER	The "unsigned" modier.
SHORT_MODIFIER	The "short" modifier.
LONG_MODIFIER	The "long" modifier.
LONG_LONG_MODIFIER	The "long long" modifier.

Member Function Documentation

get_base_type()

real_type::base_type get_base_type

(

)

const

Getter of the base type of the real_type.

Returns

the base type of the real_type.

Definition at line 16431 of file abg-ir.cc.

get_modifiers()

real_type::modifiers_type get_modifiers

(

)

const

Getter of the modifiers bitmap of the real_type.

Returns

the modifiers bitmap of the real_type.

Definition at line 16438 of file abg-ir.cc.

operator string()

operator string

(

)

const

Convert the current instance of real_type into its string representation.

Returns

the string representation of the current instance of real_type.

Definition at line 16529 of file abg-ir.cc.

operator==()

bool operator==

(

const real_type &

other

)

const

Equality operator for the real_type.

Parameters

other

the other real type to compare against.

Returns

true iff other equals the current instance of real_type.

Definition at line 16455 of file abg-ir.cc.

set_modifiers()

void set_modifiers

(

modifiers_type

m

)

Setter of the modifiers bitmap of the real_type.

Parameters

m	the new modifiers.

Definition at line 16445 of file abg-ir.cc.

to_string()

string to_string

(

bool

internal = false

)

const

Return the string representation of the current instance of real_type.

Parameters

internal

if true the string representation is to be used for internal purposes. In general, it means it's for type canonicalization purposes.

Returns

the string representation of the current instance of real_type.
