       sancov - manual page for sancov 6.0

DESCRIPTION

       OVERVIEW: Sanitizer Coverage Processing Tool (sancov)

              This  tool  can  extract  various  coverage-related information from: coverage-instrumented binary
              files, raw .sancov files and their symbolized .symcov version.  Depending  on  chosen  action  the
              tool expects different input files:

       -print-coverage-pcs     - coverage-instrumented binary files

       -print-coverage         - .sancov files

       <other actions>
              - .sancov files & corresponding binary files, .symcov files

       USAGE: sancov [options] <action> <binary files...> <.sancov files...> <.symcov files...>
