| <h4 class="subsection">9.24.3 Directives for debugging information</h4> |
| |
| <p><a name="index-MIPS-debugging-directives-1270"></a><span class="sc">mips</span> <span class="sc">ecoff</span> <code>as</code> supports several directives used for |
| generating debugging information which are not support by traditional <span class="sc">mips</span> |
| assemblers. These are <code>.def</code>, <code>.endef</code>, <code>.dim</code>, <code>.file</code>, |
| <code>.scl</code>, <code>.size</code>, <code>.tag</code>, <code>.type</code>, <code>.val</code>, |
| <code>.stabd</code>, <code>.stabn</code>, and <code>.stabs</code>. The debugging information |
| generated by the three <code>.stab</code> directives can only be read by <span class="sc">gdb</span>, |
| not by traditional <span class="sc">mips</span> debuggers (this enhancement is required to fully |
| support C++ debugging). These directives are primarily used by compilers, not |
| assembly language programmers! |
