| <h4 class="subsection">17.21.4 File Names in DBX Format</h4> |
| |
| <p>This describes file names in DBX format. |
| </p> |
| <dl> |
| <dt><a name="index-DBX_005fOUTPUT_005fMAIN_005fSOURCE_005fFILENAME"></a>Macro: <strong>DBX_OUTPUT_MAIN_SOURCE_FILENAME</strong> <em>(<var>stream</var>, <var>name</var>)</em></dt> |
| <dd><p>A C statement to output DBX debugging information to the stdio stream |
| <var>stream</var>, which indicates that file <var>name</var> is the main source |
| file—the file specified as the input file for compilation. |
| This macro is called only once, at the beginning of compilation. |
| </p> |
| <p>This macro need not be defined if the standard form of output |
| for DBX debugging information is appropriate. |
| </p> |
| <p>It may be necessary to refer to a label equal to the beginning of the |
| text section. You can use ‘<samp>assemble_name (stream, ltext_label_name)</samp>’ |
| to do so. If you do this, you must also set the variable |
| <var>used_ltext_label_name</var> to <code>true</code>. |
| </p></dd></dl> |
| |
| <dl> |
| <dt><a name="index-NO_005fDBX_005fMAIN_005fSOURCE_005fDIRECTORY"></a>Macro: <strong>NO_DBX_MAIN_SOURCE_DIRECTORY</strong></dt> |
| <dd><p>Define this macro, with value 1, if GCC should not emit an indication |
| of the current directory for compilation and current source language at |
| the beginning of the file. |
| </p></dd></dl> |
| |
| <dl> |
| <dt><a name="index-NO_005fDBX_005fGCC_005fMARKER"></a>Macro: <strong>NO_DBX_GCC_MARKER</strong></dt> |
| <dd><p>Define this macro, with value 1, if GCC should not emit an indication |
| that this object file was compiled by GCC. The default is to emit |
| an <code>N_OPT</code> stab at the beginning of every source file, with |
| ‘<samp>gcc2_compiled.</samp>’ for the string and value 0. |
| </p></dd></dl> |
| |
| <dl> |
| <dt><a name="index-DBX_005fOUTPUT_005fMAIN_005fSOURCE_005fFILE_005fEND"></a>Macro: <strong>DBX_OUTPUT_MAIN_SOURCE_FILE_END</strong> <em>(<var>stream</var>, <var>name</var>)</em></dt> |
| <dd><p>A C statement to output DBX debugging information at the end of |
| compilation of the main source file <var>name</var>. Output should be |
| written to the stdio stream <var>stream</var>. |
| </p> |
| <p>If you don’t define this macro, nothing special is output at the end |
| of compilation, which is correct for most machines. |
| </p></dd></dl> |
| |
| <dl> |
| <dt><a name="index-DBX_005fOUTPUT_005fNULL_005fN_005fSO_005fAT_005fMAIN_005fSOURCE_005fFILE_005fEND"></a>Macro: <strong>DBX_OUTPUT_NULL_N_SO_AT_MAIN_SOURCE_FILE_END</strong></dt> |
| <dd><p>Define this macro <em>instead of</em> defining |
| <code>DBX_OUTPUT_MAIN_SOURCE_FILE_END</code>, if what needs to be output at |
| the end of compilation is an <code>N_SO</code> stab with an empty string, |
| whose value is the highest absolute text address in the file. |
