<p><a name="index-g_t_0040code_007bloc_007d-directive-396"></a>When emitting DWARF2 line number information,
|
||
|
|
the <code>.loc</code> directive will add a row to the <code>.debug_line</code> line
|
||
|
|
number matrix corresponding to the immediately following assembly
|
||
|
|
instruction. The <var>fileno</var>, <var>lineno</var>, and optional <var>column</var>
|
||
|
|
arguments will be applied to the <code>.debug_line</code> state machine before
|
||
|
|
the row is added.
|
||
|
|
|
||
|
|
<p>The <var>options</var> are a sequence of the following tokens in any order:
|
||
|
|
|
||
|
|
<dl>
|
||
|
|
<dt><code>basic_block</code><dd>This option will set the <code>basic_block</code> register in the
|
||
|
|
<code>.debug_line</code> state machine to <code>true</code>.
|
||
|
|
|
||
|
|
<br><dt><code>prologue_end</code><dd>This option will set the <code>prologue_end</code> register in the

<br><dt><code>epilogue_begin</code><dd>This option will set the <code>epilogue_begin</code> register in the

|
||
|
|
|
||
|
|
<br><dt><code>is_stmt </code><var>value</var><dd>This option will set the <code>is_stmt</code> register in the

|
|
either 0 or 1.
|
||
|
|
|
||
|
|
<br><dt><code>isa </code><var>value</var><dd>This directive will set the <code>isa</code> register in the <code>.debug_line</code>
|
||
|
|
state machine to <var>value</var>, which must be an unsigned integer.
|
||
|
|
|
||
|
|
<br><dt><code>discriminator </code><var>value</var><dd>This directive will set the <code>discriminator</code> register in the <code>.debug_line</code>
