Jan Kratochvil: Remove /dev/null redirection. >>>>> "Tom" == Tom Tromey writes: Tom> This patch series adds support for a DWARF index to gdb. Roland suggested we wrap up the index-creation code into a helper script. I'm not sure if this is something people would want in gdb proper, but I figured I would send it here just in case.
