Hi All I want to follow below steps to generate code coverage data based the default build. But I notice currently GCC compiler flags won't generate *gcda and *.gcno. So add the CC flags to generate necessary data that require by "lcov" tool.
I'm not sure whether have any concern to add the flags by default. Step1. sudo apt-get install lcov Step2. stuart_ci_build -c .pytool/CISettings.py -p MdePkg -t NOOPT -a IA32,X64 TOOL_CHAIN_TAG=GCC5 --verbose Step3. lcov -c --rc lcov_branch_coverage=1 -o UnitTest.info -d Build/MdePkg/HostTest/NOOPT_GCC5/X64/MdePkg/ Step4. genhtml UnitTest.info --branch-coverage -o .Build/UnitTestReport Step5.
