Function __llvm_profile_write_file

util/system/yassert.cpp:26–28

__llvm_profile_write_file may not be provided if the executable target uses NO_CLANG_COVERAGE() macro and arrives as test's dependency via DEPENDS() macro. That's why we provide a weak no-op implementation for __llvm_profile_write_file, which is used below in the code, to correctly save codecoverage profile before program exits using abort().

    // That's why we provide a weak no-op implementation for __llvm_profile_write_file,
    // which is used below in the code, to correctly save codecoverage profile before program exits using abort().
    Y_WEAK int __llvm_profile_write_file(void) {
        return 0;
