We are not instrumenting calls except in ctx mode. In ctx we instrument calls but not indirect ones |

Hello, I am a beginner. I would like to know how AFL++'s LTO mode handles introduction calls?
I saw in the SanitizerCoverageLTO.so.cc file that
SanCovTracePCIndir = M.getOrInsertFunction(SanCovTracePCIndirName, VoidTy, IntptrTy);But I couldn't find the implementation of __ sanitizer_cov_trace_pc_indir.
I also want to know if there is a coverage loss issue with Sanitizer Coverage using LLVM, as it simulates edges by inserting basic blocks.
