These inputs were pre-generated to allow for easier testing of llvm-cov.
-test.gcno and test.gcda were create by running clang:
- clang++ -g -ftest-coverage -fprofile-arcs test.cpp
+The files used to test the gcov compatible code coverage tool were generated
+using the following method:
-test.cpp.gcov was created by running gcov 4.2.1:
- gcov test.cpp
+ test.gcno and test.gcda were create by running clang:
+ clang++ -g -ftest-coverage -fprofile-arcs test.cpp
+
+ test.cpp.gcov was created by running gcov 4.2.1:
+ gcov test.cpp
+
+The 'covmapping' files that are used to test llvm-cov contain raw sections
+with the coverage mapping data generated by the compiler and linker. They are
+created by running clang and llvm-cov:
+ clang++ -fprofile-instr-generate -fcoverage-mapping -o test test.cpp
+ llvm-cov convert-for-testing -o test.covmapping test
+
+The 'profdata' files were generated by running an instrumented version of the
+program and merging the raw profile data using llvm-profdata.
+ ./test
+ llvm-profdata merge -o test.profdata default.profraw
