[lldb-dev] Code coverage of llvm, clang, lldb & polly

Thanks for putting together the report, Sylvestre,

Do you have any indication that lcov/gcov has any support for dynamically loaded shared libraries?  Note that much of lldb consists of plug-ins that are platform or architecture specific, and these are on the critical path for coverage.  For instance, the report shows 0% coverage for many directories in lldb/source like /Expression and /DataFormatters, whereas the current test suite should give us something...

Plugged in the Jenkins instance used to build Debian & Ubuntu nightly package, I configured a code coverage tool (lcov) with all the tests of these projects.
Results are published here:

This URL is updated twice a day (it might change since it is taking a long time).

For those who would like to have their own setup, with gcc, use the following declaration:
CXXFLAGS="-fprofile-arcs -ftest-coverage"  LDFLAGS="-coverage -lgcov"

Rebuild everything, launch the tests and run:

mkdir -p $BUILD_DIR
lcov --directory $BUILD_DIR --capture --ignore-errors source --output-file $REPORT lcov --remove $REPORT "/usr*" -o $REPORT lcov --remove $REPORT "$BUILD_DIR/*" -o $REPORT genhtml -o reports/coverage --show-details --highlight --legend $REPORT
