<h4 class="subsubsection">23.2.2.33 Python representation of architectures</h4>
<a name="index-Python-architectures"></a>

<p><small>GDB</small> uses architecture specific parameters and artifacts in a
number of its various computations.  An architecture is represented
by an instance of the <code>gdb.Architecture</code> class.
</p>
<p>A <code>gdb.Architecture</code> class has the following methods:
</p>
<dl>
<dt><a name="index-Architecture_002ename"></a>Function: <strong>Architecture.name</strong> <em>()</em></dt>
<dd><p>Return the name (string value) of the architecture.
</p></dd></dl>

<dl>
<dt><a name="index-Architecture_002edisassemble"></a>Function: <strong>Architecture.disassemble</strong> <em>(<var>start_pc</var> <span class="roman">[</span>, <var>end_pc</var> <span class="roman">[</span>, <var>count</var><span class="roman">]]</span>)</em></dt>
<dd><p>Return a list of disassembled instructions starting from the memory
address <var>start_pc</var>.  The optional arguments <var>end_pc</var> and
<var>count</var> determine the number of instructions in the returned list.
If both the optional arguments <var>end_pc</var> and <var>count</var> are
specified, then a list of at most <var>count</var> disassembled instructions
whose start address falls in the closed memory address interval from
<var>start_pc</var> to <var>end_pc</var> are returned.  If <var>end_pc</var> is not
specified, but <var>count</var> is specified, then <var>count</var> number of
instructions starting from the address <var>start_pc</var> are returned.  If
<var>count</var> is not specified but <var>end_pc</var> is specified, then all
instructions whose start address falls in the closed memory address
interval from <var>start_pc</var> to <var>end_pc</var> are returned.  If neither
<var>end_pc</var> nor <var>count</var> are specified, then a single instruction at
<var>start_pc</var> is returned.  For all of these cases, each element of the
returned list is a Python <code>dict</code> with the following string keys:
</p>
<dl compact="compact">
<dt><code>addr</code></dt>
<dd><p>The value corresponding to this key is a Python long integer capturing
the memory address of the instruction.
</p>
</dd>
<dt><code>asm</code></dt>
<dd><p>The value corresponding to this key is a string value which represents
the instruction with assembly language mnemonics.  The assembly
language flavor used is the same as that specified by the current CLI
variable <code>disassembly-flavor</code>.  See <a href="Machine-Code.html#Machine-Code">Machine Code</a>.
</p>
</dd>
<dt><code>length</code></dt>
<dd><p>The value corresponding to this key is the length (integer value) of the
instruction in bytes.
</p>
</dd>
</dl>
</dd></dl>

<a name="gdbpy_005farchitecture_005fregisters"></a><dl>
<dt><a name="index-Architecture_002eregisters"></a>Function: <strong>Architecture.registers</strong> <em>(<span class="roman">[</span> <var>reggroup</var> <span class="roman">]</span>)</em></dt>
<dd><p>Return a <code>gdb.RegisterDescriptorIterator</code> (see <a href="Registers-In-Python.html#Registers-In-Python">Registers In Python</a>) for all of the registers in <var>reggroup</var>, a string that is
the name of a register group.  If <var>reggroup</var> is omitted, or is the
empty string, then the register group &lsquo;<samp>all</samp>&rsquo; is assumed.
</p></dd></dl>

<a name="gdbpy_005farchitecture_005freggroups"></a><dl>
<dt><a name="index-Architecture_002eregister_005fgroups"></a>Function: <strong>Architecture.register_groups</strong> <em>()</em></dt>
<dd><p>Return a <code>gdb.RegisterGroupsIterator</code> (see <a href="Registers-In-Python.html#Registers-In-Python">Registers In Python</a>) for all of the register groups available for the
<code>gdb.Architecture</code>.
</p></dd></dl>
