<h3>NAME</h3>
|
|
<tt>llvm-prof</tt>
|
|
|
|
<h3>SYNOPSIS</h3>
|
|
<tt>llvm-prof [options] [bytecode file] [llvmprof.out]</tt>
|
|
|
|
<h3>DESCRIPTION</h3>
|
|
|
|
The <tt>llvm-prof</tt> tool reads in an '<tt>llvmprof.out</tt>' file (which can
|
|
optionally use a specific file with the third program argument), a bytecode file
|
|
for the program, and produces a human readable report, suitable for determining
|
|
where the program hotspots are.<p>
|
|
|
|
This program is often used in conjunction with the <tt>utils/profile.pl</tt>
|
|
script. This script automatically instruments a program, runs it with the JIT,
|
|
then runs <tt>llvm-prof</tt> to format a report. To get more information about
|
|
<tt>utils/profile.pl</tt>, execute it with the <tt>--help</tt> option.<p>
|
|
|
|
<h3>OPTIONS</h3>
|
|
|
|
<ul>
|
|
<li><tt>--annotated-llvm</tt> or <tt>-A</tt><br>
|
|
|
|
In addition to the normal report printed, print out the code for the
|
|
program, annotated we execution frequency information. This can be
|
|
particularly useful when trying to visualize how frequently basic blocks
|
|
are executed. This is most useful with basic block profiling
|
|
information or better.<p>
|
|
|
|
<li><tt>--print-all-code</tt><br>
|
|
|
|
Using this option enables the <tt>--annotated-llvm</tt> option, but it
|
|
prints the entire module, instead of just the most commonly executed
|
|
functions.<p>
|
|
</ul>
|
|
|
|
<h3>EXIT STATUS</h3>
|
|
|
|
<tt>llvm-prof</tt> returns 1 if it cannot load the bytecode file or the profile
|
|
information, otherwise it exits with zero.
