A computing device determines a first set of functions in a first file having a first bit length. The computing device performs a first test, which includes executing a first test program capable of testing each function in the first set of functions. The computing device determines whether the first test was successful, and based on determining that the first test was successful, creates a shim program based on the first set of functions. The computing device creates a second file based on the first set of functions, the second file having a second bit length. The computing device performs a second test, which includes executing a second test program capable of testing each function in the second file. The computing device determines whether the second test was successful, and based on determining that the second test was successful, publishes one or more of the shim program and second file.
