catobj - ISOS object file concatenator
catobj [options] [-no-warn-shared] [-no-prefix-tors] [-o] dest obj1 obj2 ...
There is normally no need to use catobj directly.
catobj concatenates multiple object files into a single partially linked object file. arm-elf-objcopy modifies the image symbols as needed. arm-elf-ld then partially links the objects.
