Abstract: Systems and methods are provided for programmatically generating programs that control software linkers to place new executable binary code and/or data patches in existing, executable binaries, which may be fully-linked. Examples disclosed herein include obtaining a first executable; obtaining target information that identifies unused space in the first executable; obtaining one or more routines; generating a linker control program based on the target information and the one or more routines; linking, by the linker control program, the one or more routines into one or more second executables; and patching the first executable with the one or more second executables.
