|
|
<p>Change the logical line number. <var>line-number</var> must be an absolute
|
|
expression. The next line has that logical line number. Therefore any other
|
|
statements on the current line (after a statement separator character) are
|
|
reported as on logical line number <var>line-number</var> - 1. One day
|
|
<code>as</code> will no longer support this directive: it is recognized only
|
|
for compatibility with existing assembler programs.
|
|
</p>
|
|
<p>Even though this is a directive associated with the <code>a.out</code> or
|
|
<code>b.out</code> object-code formats, <code>as</code> still recognizes it
|
|
when producing COFF output, and treats ‘<samp>.line</samp>’ as though it
|
|
were the COFF ‘<samp>.ln</samp>’ <em>if</em> it is found outside a
|
|
<code>.def</code>/<code>.endef</code> pair.
|
|
</p>
|
|
<p>Inside a <code>.def</code>, ‘<samp>.line</samp>’ is, instead, one of the directives
|
|
used by compilers to generate auxiliary symbol information for
|
|
debugging.
