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, kernel
              modules and the kernel. This option only makes sense if the pro-
              file session used --separate.

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

       --image-path / -p [paths]
              Comma-separated list of additional paths to search for binaries.
              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.
