Redundant run-time type information is removed from a compiled program. The redundant type information may be unneeded and/or duplicate. Unneeded type information is removed by selecting instances of type information from read only data sections of object files. The entire compiled program is searched for instructions that use the instances. The instances that do not correspond to such instructions are removed from the object files. Duplicate type information is removed by selecting instances of type information from read only data sections of object files. The read only data sections of the other object files in the compiled program are then searched for the selected instances. The selected instances that exist in the read only data sections of the other object files are removed. Redundant type information may be removed from individual object files before concatenation into a single binary file and/or from a single binary file after concatenation.
