<li>DWARF4 is now the default when generating DWARF debug information.
- When -g is used on a platform that uses DWARF debugging information,
- GCC will now default to -gdwarf-4 -fno-debug-types-section.

GDB 7.5, Valgrind 3.8.0 and elfutils 0.154 debug information consumers
support DWARF4 by default. Before GCC 4.8 the default version used
- was DWARF2. To make GCC 4.8 generate an older DWARF version use -g
- together with -gdwarf-2 or -gdwarf-3. The default for Darwin and
