NAME
       opstack - produce callgraph symbol summaries

SYNOPSIS
       opstack [ options ] [profile specification]

DESCRIPTION
       opstack	outputs	 binary	 callgraph  symbol summaries. Currently, this
       requires an x86-based box and a 2.6  kernel  patch;  see	 http://opro-
       file.sf.net/patches/.


OPTIONS
       --accumulated / -c
	      Accumulate sample and percentage counts in the symbol list.

       --debug-info / -g
	      Show source file and line for each symbol.

       --demangle=none|smart|normal
	      none:  no	 demangling.  normal: use default demangler (default)
	      smart: use pattern-matching to make C++ symbol demangling	 more
	      readable.

       --show-address / -w
	      Show each symbol’s VMA address.

       --no-header
	      Don’t output a header detailing profiling parameters.

       --long-filenames / -l
	      Output full paths instead of basenames.

       --exclude-dependent / -x
	      Do  not include application-specific images for libraries, ker-
	      nel modules and the kernel. This option only makes sense if the
	      profile session used --separate.

       --help / -? / --usage
	      Show help message.

       --image-path / -p [paths]
	      Comma-separated  list  of	 additional paths to search for bina-
	      ries.  This is needed  to	 find  modules	in  kernels  2.6  and
	      upwards.

       --merge / -m [lib,cpu,tid,tgid,unitmask,all]
	      Merge any profiles separated in a --separate session.

       --threshold / -t [percentage]
	      Only output data for symbols that have more than the given per-
	      centage of total samples.

       --verbose / -V [options]
	      Give verbose debugging output.

       --version / -v
	      Show version.
