<p>These are hooks for DBX format.

<dt><a name="index-DBX_005fOUTPUT_005fSOURCE_005fLINE"></a>Macro: <strong>DBX_OUTPUT_SOURCE_LINE</strong> <em>(<var>stream</var>, <var>line</var>, <var>counter</var>)</em></dt>
<dd><p>A C statement to output DBX debugging information before code for line
number <var>line</var> of the current source file to the stdio stream
<var>stream</var>.  <var>counter</var> is the number of time the macro was
invoked, including the current invocation; it is intended to generate
unique labels in the assembly output.
</p>
<p>This macro should not be defined if the default output is correct, or
if it can be made correct by defining <code>DBX_LINES_FUNCTION_RELATIVE</code>.

<dl>
<dt><a name="index-NO_005fDBX_005fFUNCTION_005fEND"></a>Macro: <strong>NO_DBX_FUNCTION_END</strong></dt>
<dd><p>Some stabs encapsulation formats (in particular ECOFF), cannot handle the
<code>.stabs &quot;&quot;,N_FUN,,0,0,Lscope-function-1</code> gdb dbx extension construct.
On those machines, define this macro to turn this feature off without
disturbing the rest of the gdb extensions.

<dl>
<dt><a name="index-NO_005fDBX_005fBNSYM_005fENSYM"></a>Macro: <strong>NO_DBX_BNSYM_ENSYM</strong></dt>
<dd><p>Some assemblers cannot handle the <code>.stabd BNSYM/ENSYM,0,0</code> gdb dbx
extension construct.  On those machines, define this macro to turn this
feature off without disturbing the rest of the gdb extensions.
