| <h5 class="subsubsection">23.2.2.33 Python representation of architectures</h5> |
| |
| <p><a name="index-Python-architectures-2434"></a> |
| <span class="sc">gdb</span> 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>A <code>gdb.Architecture</code> class has the following methods: |
| |
| <div class="defun"> |
| — Function: <b>Architecture.name</b> ()<var><a name="index-Architecture_002ename-2435"></a></var><br> |
| <blockquote><p>Return the name (string value) of the architecture. |
| </p></blockquote></div> |
| |
| <div class="defun"> |
| — Function: <b>Architecture.disassemble</b> (<var>start_pc </var><span class="roman">[</span><var>, end_pc </var><span class="roman">[</span><var>, count</var><span class="roman">]]</span>)<var><a name="index-Architecture_002edisassemble-2436"></a></var><br> |
| <blockquote><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: |
| |
| <dl> |
| <dt><code>addr</code><dd>The value corresponding to this key is a Python long integer capturing |
| the memory address of the instruction. |
| |
| <br><dt><code>asm</code><dd>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>. |
| |
| <br><dt><code>length</code><dd>The value corresponding to this key is the length (integer value) of the |
| instruction in bytes. |
