Clang and llvm have been upgraded to 3.4 release.
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.
