1. A computer program product for optimized compiling of a template function, the computer program product comprising: one or more computer readable non-transitory storage media; and program instructions stored on the one or more computer readable non-transitory storage media, the program instructions comprising: program instructions to receive the template function, wherein the template function includes one or more data types; program instructions to create a single abstract instantiation for the template function; program instructions to create an abstract internal descriptor for each unique parameter found in the template function, wherein the each unique parameter consists of parameters for each of the one or more data types included in the template function, and wherein the each unique parameter for the each data type of the one or more data types is represented by symbols with various attributes in a compiler, and wherein the abstract internal descriptor is an internal symbol with undefined contents; program instructions to generate a map set for the one or more created abstract internal descriptor, wherein the map set is a link between the template function and the parameters in the template function and wherein the map set provides one or more of the following: the number of instantiations required from the single abstract instantiation and what type of instantiations are required; and program instructions to create a finished object using the generated map set, wherein the finished object is a translation of an intermediate representation into assembly code and the finished object is an executable file, wherein the program instructions to create the finished object comprises: program instructions to execute a single back-end compiler optimization of a single front-end compiler abstract instantiation, wherein the front-end compiler abstract instantiation and the back-end compiler optimization are steps for converting a source code into the executable file; and program instructions to create the executable file via late instantiation of an optimized abstract instantiation.
