| <p>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 <small>GDB</small> for the fundamental |
| types. The currently supported types are: |
| </p> |
| <dl compact="compact"> |
| <dt><code>int8</code></dt> |
| <dt><code>int16</code></dt> |
| <dt><code>int32</code></dt> |
| <dt><code>int64</code></dt> |
| <dt><code>int128</code></dt> |
| <dd><p>Signed integer types holding the specified number of bits. |
| </p> |
| </dd> |
| <dt><code>uint8</code></dt> |
| <dt><code>uint16</code></dt> |
| <dt><code>uint32</code></dt> |
| <dt><code>uint64</code></dt> |
| <dt><code>uint128</code></dt> |
| <dd><p>Unsigned integer types holding the specified number of bits. |
| </p> |
| </dd> |
| <dt><code>code_ptr</code></dt> |
| <dt><code>data_ptr</code></dt> |
| <dd><p>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. |
| </p> |
| </dd> |
| <dt><code>ieee_single</code></dt> |
| <dd><p>Single precision IEEE floating point. |
| </p> |
| </dd> |
| <dt><code>ieee_double</code></dt> |
| <dd><p>Double precision IEEE floating point. |
| </p> |
| </dd> |
| <dt><code>arm_fpa_ext</code></dt> |
| <dd><p>The 12-byte extended precision format used by ARM FPA registers. |
| </p> |
| </dd> |
| <dt><code>i387_ext</code></dt> |
| <dd><p>The 10-byte extended precision format used by x87 registers. |
| </p> |
| </dd> |
| <dt><code>i386_eflags</code></dt> |
| <dd><p>32bit <small>EFLAGS</small> register used by x86. |
