Member Function Documentation

◆ add_dyn_prop()

void type::add_dyn_prop ( dynamic_prop_node_kind  kind,
dynamic_prop  prop

Given a dynamic property PROP of a given KIND, add this dynamic property to this type.

This function assumes that this type is objfile-owned.

Return the bit offset for this integer type. Only valid for integer (TYPE_SPECIFIC_INT) types.

Definition at line 1387 of file gdbtypes.h.

◆ bit_size()

unsigned short type::bit_size ( ) const

Member Data Documentation

◆ align_log2

unsigned type::align_log2

The alignment for this type. Zero means that the alignment was not specified in the debug info. Note that this is stored in a funny way: as the log base 2 (plus 1) of the alignment; so a value of 1 means the alignment is 1, and a value of 9 means the alignment is 256.

Definition at line 1429 of file gdbtypes.h.

◆ chain

struct type* type::chain

Variant chain. This points to a type that differs from this one only in qualifiers and length. Currently, the possible qualifiers are const, volatile, code-space, data-space, and address class. The length may differ only when one of the address class flags are set. The variants are linked in a circular ring and share MAIN_TYPE.

Definition at line 1421 of file gdbtypes.h.

◆ m_instance_flags

unsigned type::m_instance_flags

Flags specific to this instance of the type, indicating where on the ring we are.

For TYPE_CODE_TYPEDEF the flags of the typedef type should be binary or-ed with the target type, with a special case for address class and space class. For example if this typedef does not specify any new qualifiers, TYPE_INSTANCE_FLAGS is 0 and the instance flags are completely inherited from the target type. No qualifiers can be cleared by the typedef. See also check_typedef.

Definition at line 1441 of file gdbtypes.h.

◆ m_length

ULONGEST type::m_length

Length of storage for a value of this type. The value is the expression in host bytes of what sizeof(type) would return. This size includes padding. For example, an i386 extended-precision floating point value really only occupies ten bytes, but most ABI's declare its size to be 12 bytes, to preserve alignment. A ‘struct type’ representing such a floating-point type would have a ‘length’ value of 12, even though the last two bytes are unused.

Since this field is expressed in host bytes, its value is appropriate to pass to memcpy and such (it is assumed that GDB itself always runs on an 8-bits addressable architecture). However, when using it for target address arithmetic (e.g. adding it to a target address), the type_length_units function should be used in order to get the length expressed in target addressable memory units.

Definition at line 1459 of file gdbtypes.h.

◆ main_type

struct main_type* type::main_type

Core type, shared by a group of qualified types.

Definition at line 1463 of file gdbtypes.h.

◆ pointer_type

struct type* type::pointer_type

Type that is a pointer to this type. NULL if no such pointer-to type is known yet. The debugger may add the address of such a type if it has to construct one later.

Definition at line 1404 of file gdbtypes.h.

◆ reference_type

struct type* type::reference_type

C++: also need a reference type.

Definition at line 1408 of file gdbtypes.h.

◆ rvalue_reference_type

struct type* type::rvalue_reference_type

A C++ rvalue reference type added in C++11.
