<p><a name="index-line-comment-character_002c-TIC6X-2205"></a><a name="index-TIC6X-line-comment-character-2206"></a>The presence of a ‘<samp><span class="samp">;</span></samp>’ on a line indicates the start of a comment
|
|
that extends to the end of the current line. If a ‘<samp><span class="samp">#</span></samp>’ or
|
|
‘<samp><span class="samp">*</span></samp>’ appears as the first character of a line, the whole line is
|
|
treated as a comment. Note that if a line starts with a ‘<samp><span class="samp">#</span></samp>’
|
|
character then it can also be a logical line number directive
|
|
(see <a href="Comments.html#Comments">Comments</a>) or a preprocessor control command
|
|
(see <a href="Preprocessing.html#Preprocessing">Preprocessing</a>).

|
|
statements.
|
|
|
|
<p>Instruction, register and functional unit names are case-insensitive.
|
|
<samp><span class="command">as</span></samp> requires fully-specified functional unit names,
|
|
such as ‘<samp><span class="samp">.S1</span></samp>’, ‘<samp><span class="samp">.L1X</span></samp>’ or ‘<samp><span class="samp">.D1T2</span></samp>’, on all instructions
|
|
using a functional unit.
|
|
|
|
<p>For some instructions, there may be syntactic ambiguity between
|
|
register or functional unit names and the names of labels or other
|
|
symbols. To avoid this, enclose the ambiguous symbol name in
|
|
parentheses; register and functional unit names may not be enclosed in
|
|
parentheses.
