llvm dev - Apr 2018 - Which code coverage approach is suggested from LLVM

Hi,
I see there are multiple code coverage solution infras supported by LLVM.

  *   LLVM native support code coverage (Source-based code coverage)
  *   Gcc’s/gcov native code coverage support and
  *   Sanitizer coverage

All 3 of them are quite different. So, in terms of future support and technical
aspects wise, would you please help me understand which one is preferred one? I
am basically looking for a solution for C code base. Your quick help would be
highly appreciated.

Best regards
Vasu
