Add optional coverage flags to build
This CL allows generating coverage information for the source files. By adding use_coverage=true to the GN build settings clang will generate .gcno files for each source file and executing the binary will generate a .gcda file for each source file. Those files can then be processed by llvm-cov to generate .gcov reports for each source file. i.e. (assuming use_coverage=true is set for out/coverage) * ninja -C out/coverage pdfium_unittests * cd out/coverage * find obj -name "*.o" -exec llvm-cov -af -stats {} > d.out \; There should now be .gcov files for each source file in the out/coverage directory. Note, llvm-gcov may have a different name or syntax on your machine.
