I can capture llc coverage by llvm-cov and llvm-profdata. But if the llc execution fails (crash as shown below), how can I capture its coverage ?? In this case, coverage files whose name is ends with ".profraw" fail to be generated so the previous method of getting coverage failed. If someone can help me, I will be very grateful!!!
