liblzma/tests/code_coverage.sh
Jia Tan d1bfa3dc70 Created script to generate code coverage reports.
The script uses lcov and genhtml after running the tests
to show the code coverage statistics. The script will create
a coverage directory where it is run. It can be run both in
and out of the source directory.

# This builds xz with special CFLAGS for measuring code coverage and
# uses lcov and genhtml to create coverage reports.
#
# The current directory is used as the build directory so out-of-tree
# builds are possible. The coverage reports are written to the directory
# "coverage" under the current directory.
#
# Any options passed to this script are passed to "make" so to get
# faster builds use, for example, "-j4" as an argument to this script.
