<h3>NAME</h3>
|
||
|
|
<tt>llvm-prof</tt>
|
||
|
|
|
||
|
|
<h3>SYNOPSIS</h3>
|
||
|
|
<tt>llvm-prof [options] [bytecode file] [LLVM passes]</tt>
|
||
|
|
|
||
|
|
<h3>DESCRIPTION</h3>
|
||
|
|
|
||
|
|
The <tt>llvm-prof</tt> tool reads in an '<tt>llvmprof.out</tt>' file, a bytecode
|
||
|
|
file for the program, and produces a human readable report, suitable for
|
||
|
|
determining where the program hotspots are.<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>
|
||
|
|
</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.
