BTW, -gdwarf-4 forces the emission of debug information in DWARF4 format. Clang has added an extra flag -fdebug-default-version to specify which version is the default without forcing the output of debug information (https://reviews.llvm.org/D69822). What's the intended effect here: emit the debug information in default format (-g) or don't emit it at all (removed flag)? |
