+ <a name="Jitrino.OPT Internal Profiler Tool">Jitrino.OPT Internal Profiler Tool</a>
+ </h1>
+ <p>This document defines the internal
+profiler tool (iprof) for <a href="JIT.html">Jitrino.OPT</a>
+code generator and describes how to use it. The internal profiler can instrument
+ code so that per-method counters of <i>executed</i> (not just compiled)
+ instructions can be dumped. Operation of iprof is configured in the <code>iprof.cfg</code>
+ file, as described in this document. For sample iprof tool output, see the<a href="#ExampleOutput">example</a>.</p>
+ <p> To enable iprof, do the following:</p>
+ <ol>
+ <li>Specify the following additional command-line options to DRLVM on startup: <code><br />
+ -XcleanupOnExit -XDjit.arg.codegen.iprof=on</code></li>
+ <li> Place the configuration file <code>iprof.cfg</code> in the same directory
+ where you are starting DRLVM.</li>
+</ol>
+
+ <h2>
+ <a name="Configuring the Profiler">Configuring the Profiler</a>
+ </h2>
+
+ <p>The configuration file <code>iprof.cfg</code> consists of a list of global parameters
+ and a list of counters, as defined in this section. For a sample iprof configuration,
+ see the <a href="#ExampleConfig">example</a>. </p>
+ <h3>Available global parameters</h3>
+ <pre>Config.PrintBBStats=false #(boolean)</pre>
+ <p>This parameter turns on statistics dumping for all
+basic blocks of a method.</p>
+ <h3>Counters</h3>
+ <p>Counters collect information about executed
+ instructions defined by the filter.
+ Counters have the following attributes:</p>
+ <ul>
+ <li><em>Name</em> identifies the counter. This attribute is defined by the first
+ line in a <code>[begin]/[end]</code> section starting with <code>Counter.</code>,
+ and all symbols after it and up to
+ the next period <code>.</code> or an
+ equal mark <code>=</code> or <code>\n</code> constitute the name of the counter.</li>
+ <li><em>Title</em> is the for the dumped column. [optional]</li>
+ <li><em>Filter</em> lists properties of
+ the instructions to count. You can define properties for the instruction
+ (mnemonic, the number of operands), for a specific operand (for example,
+ the area of placement) or include run-time information (for example, whether
+ the call is a helper and the helper name). See the list of filter parameters
+ below.
+ <br />All filter parameters can be considered parts
+ of an <code>AND</code> expression. You can also use the
+ <code>IsOr</code> filter attribute to provide an <code>OR</code> operation for all filter parameters, for example:
+ <br /><code>Counter.Name0.IsOr=true</code></li>
+</ul>
+ <p class="example">Example</p>

+ <h3>Re-using Filter Parameters between Counters </h3>
+ <p>Filter parameters of a counter can be re-used and
+extended by another counter, for example:</p>
