 | | Compilation comprises running a separate computer program, termed a compiler, in order to convert a high level language program (the source code) possessing the desired attributes of flexibility and ease of use, into a sequence of steps (object code) which are executable on the hardware of a particular computing machine. |
 | | While a compiler might be designed in blocks or modules, where each such block performed a separate task, and a particular set of such tasks was recognized in the field as being required for compilation, in each case compiler design required that the entire design process be repeated de novo. |
 | | Accordingly, it is a further object of the present invention to develop a group of compilers (compiling various high level languages onto various target machines) which optimize a universal intermediate language. |
