Changes in directory llvm/docs:
LangRef.html updated: 1.158 -> 1.159 --- Log message: For PR950: http://llvm.org/PR950 : Make necessary changes to support DIV -> [SUF]Div. This changes llvm to have three division instructions: signed, unsigned, floating point. The bytecode and assembler are bacwards compatible, however. --- Diffs of the changes: (+59 -13) LangRef.html | 72 ++++++++++++++++++++++++++++++++++++++++++++++++----------- 1 files changed, 59 insertions(+), 13 deletions(-) Index: llvm/docs/LangRef.html diff -u llvm/docs/LangRef.html:1.158 llvm/docs/LangRef.html:1.159 --- llvm/docs/LangRef.html:1.158 Sun Oct 15 15:05:59 2006 +++ llvm/docs/LangRef.html Thu Oct 26 01:15:43 2006 @@ -77,7 +77,9 @@ <li><a href="#i_add">'<tt>add</tt>' Instruction</a></li> <li><a href="#i_sub">'<tt>sub</tt>' Instruction</a></li> <li><a href="#i_mul">'<tt>mul</tt>' Instruction</a></li> - <li><a href="#i_div">'<tt>div</tt>' Instruction</a></li> + <li><a href="#i_udiv">'<tt>udiv</tt>' Instruction</a></li> + <li><a href="#i_sdiv">'<tt>sdiv</tt>' Instruction</a></li> + <li><a href="#i_fdiv">'<tt>fdiv</tt>' Instruction</a></li> <li><a href="#i_rem">'<tt>rem</tt>' Instruction</a></li> <li><a href="#i_setcc">'<tt>set<i>cc</i></tt>' Instructions</a></li> </ol> @@ -1630,26 +1632,70 @@ </pre> </div> <!-- _______________________________________________________________________ --> -<div class="doc_subsubsection"> <a name="i_div">'<tt>div</tt>' +<div class="doc_subsubsection"> <a name="i_udiv">'<tt>udiv</tt>' Instruction +</a></div> +<div class="doc_text"> +<h5>Syntax:</h5> +<pre> <result> = udiv <ty> <var1>, <var2> <i>; yields {ty}:result</i> +</pre> +<h5>Overview:</h5> +<p>The '<tt>udiv</tt>' instruction returns the quotient of its two +operands.</p> +<h5>Arguments:</h5> +<p>The two arguments to the '<tt>udiv</tt>' instruction must be +<a href="#t_integer">integer</a> values.
