When we use selective instrumentation and instrument a file that is not in the selected files list provided via -fprofile-list, we generate an empty raw profile. This leads to empty_raw_profile error when we try to read that profile. This patch fixes the issue by generating a raw profile that contains only a profile header when there are no counters and profile data. A small reproducer for the above issue: echo "src:other.cc" > code.list clang++ -O2 -fprofile-instr-generate -fcoverage-mapping -fprofile-list=code.list code.cc -o code ./code llvm-profdata show default.profraw Differential Revision: https://reviews.llvm.org/D132094 |
