Thanks. For me at least, it looked like this:
/src/llvm/tools/lldb/include/lldb/Interpreter/Args.h:155:3: error: 'auto'
return without trailing return type; deduced return types are a C++14 extension
auto begin() const { return m_entries.begin(); }
^
/src/llvm/tools/lldb/include/lldb/Interpreter/Args.h:156:3: error: 'auto'
return without trailing return type; deduced return types are a C++14 extension
auto end() const { return m_entries.end(); }
^
/src/llvm/tools/lldb/include/lldb/Interpreter/Args.h:155:31: error: no viable
conversion from returned value of type 'const_iterator' (aka
'__normal_iterator<const lldb_private::Args::ArgEntry *,
std::vector<lldb_private::Args::ArgEntry,
std::allocator<lldb_private::Args::ArgEntry> > >') to function return type 'int'
auto begin() const { return m_entries.begin(); }
^~~~~~~~~~~~~~~~~
