# This script extracts information from files produced by gcov showing what
# parts of each file have *not* been executed by the test programs.
#
# Normally, this script should *not* be used directly; instead, use
# maint/createcoverage
# The createcoverave script uses this (getcoverage) script to create the
# coverage information.
#
# To create a coverage report using this script, use the following steps:
#
# configure --enable-coverage <other options>
# make
# make install
# make testing
# < run other tests, such as the Intel, MPICH1, and C++ tests >
# make coverage
# maint/getcoverage src/mpi src/util > coverage.txt
#
# The script in mpich-tests/getcoverage will perform all of these steps
# (this script is not yet included with the MPICH distribution)
#
# As an option, create HTML versions of the files with the uncovered code
# highlighted with a different background color (e.g., pale red). These
# should be placed into the same directory structure as the original source
# files, but with a different root ($annoteSrcDir)
#
# ToDo:
# Another useful option for graphical output would be to keep track of the
# percentage of covered lines and produce an "xdu"-style map of the
# coverage, with color indicating the fraction of coverage.
#
# The GNU tools sometimes incorrectly mark "break" statements within a
# case statement as not executed. As break can also be used in a loop, where
# it is an executable statement, we can't just ignore breaks, and we can't
# determine which type the break is without parsing the program :(.
