+ Clang and llvm have been upgraded to 3.4 release. Please note that
+ clang 3.4 now defaults to DWARF4 debug information format when you
+ specify -g. Since kgdb(1) only supports DWARF2, you should update any
+ customized kernel configurations which include debug information to
+ explicitly use -gdwarf-2, e.g:
+
+ makeoptions DEBUG=-gdwarf-2
+
+ This has already been applied to the appropriate GENERIC configuration
+ files, so if you inherit from those, no changes are required.
