Doesn't the output format require llvm-cov, or no?
Yes, .gcda files generated by a Clang-built kernel could only be parsed by llvm-cov, but not gcc gcov (at least in my local tests). llvm-cov documentation also indicates that GCC and LLVM gcov tools are not necessarily compatible. "[llvm-cov] is compatible with the gcov tool from version 4.2 of GCC and may also be compatible with some later versions of gcov." https://llvm.org/docs/CommandGuide/llvm-cov.html
