Problems solved by technology

[0010] However, in the above-mentioned conventional technology, it is mandatory for the programmer to be aware that the common part of the program is described as an execution class of an unspecified type, which places a heavy burden on the programmer.

Embodiment Construction

[0052] An embodiment of the compiling method of the present invention will be described below with reference to the accompanying drawings.

[0053] FIG. 1 is a configuration diagram of a compiling step in an embodiment of the present invention.

[0054] In Fig. 1, the compiling step includes: input step S102, sentence analysis step S103, identical function definition generation judgment step S105, function definition publicization step S106, function call replacement step S107, intermediate code generation step S109, optimization step S110, Resource allocation step S111 and output step S112. Each of these compiling steps is a process performed by a compiling device including a CPU according to a compiling program.

[0055] The program storage unit D101 stores an input program to be compiled.

[0056] In the input step S102, all the programs stored in the program storage unit D101 are input in order, and passed to the sentence analysis step S103.

[0057] In the ...

Abstract

The present invention provides a template compiling method. The same function definition generates a judgment step (S105), analyzes the dependencies between function definition codes and template parameters, and in the absence of dependencies, defines a common step by function (S106) Define a public function, and delete multiple function definitions before publicizing. Then, in the function call replacement step (S107), the function before publicization is replaced with a call to a public function. In this way, among a plurality of function definition codes generated from a template, by sharing the same function definition codes, it is possible to reduce the amount of codes increased due to the template structure.

Description

technical field [0001] The invention relates to a compiling method for converting a program written in a high-level language with template structure into object code. Background technique [0002] In software development in recent years, programs have become large-scale, and accordingly, object-oriented languages ​​that are easy to maintain and highly reusable have attracted attention. [0003] C++ language can be mentioned as a representative object-oriented language. The C++ language has a template structure, which can be used for general-purpose programming with easy maintenance and high reusability. Furthermore, a standard template library called STL (StandardTemplate Library) is usually provided by a compiler, and the number of programs using template structures will increase in the future. [0004] FIG. 12 shows an example of generated code when compiling a C++ program using the template structure. [0005] As shown in source codes (a) and (b) of Figure 12, C++ is u...
