On clang, when using -fsanitize-coverage=trace-pc-guard default implementations for the callback functions are provided that produce sancov data: https://clang.llvm.org/docs/SanitizerCoverage.html#default-implementation SanitizerCoverage — Clang 13 documentation<https://clang.llvm.org/docs/SanitizerCoverage.html#default-implementation> extern "C" void __sanitizer_cov_pcs_init (const uintptr_t * pcs_beg, const uintptr_t * pcs_end) {// [pcs_beg,pcs_end) is the array of ptr-sized integers representing // pairs [PC,PCFlags] for every instrumented block in the current DSO. // Capture this array in order to read the PCs and their Flags. // The number of PCs and PCFlags for a given DSO is the same as the number // of 8-bit counters ... clang.llvm.org Are there such default implementations for gcc 9.3 and -fsanitize-coverage=trace-pc? If no, would it be easy to introduce them by another way? Regards
