F.3 Predefined Target Types

Type definitions in the self-description can build up composite types from basic building blocks, but can not define fundamental types. Instead, standard identifiers are provided by No value for GDBN for the fundamental types. The currently supported types are:

int8

int16

int32

int64

Signed integer types holding the specified number of bits.

uint8

uint16

uint32

uint64

Unsigned integer types holding the specified number of bits.

code_ptr

data_ptr

Pointers to unspecified code and data. The program counter and any dedicated return address register may be marked as code pointers; printing a code pointer converts it into a symbolic address. The stack pointer and any dedicated address registers may be marked as data pointers.

ieee_single

Single precision IEEE floating point.

ieee_double

Double precision IEEE floating point.

arm_fpa_ext

The 12-byte extended precision format used by ARM FPA registers.
