The RX family C/C++ compiler generates a file executable in the target system from the source program written in C language, C99 language, C++ language, or assembly language.

In this compiler, a single driver controls multiple phases from preprocessing to linkage.

The following describes processing in each phase.

This processes preprocessing directives, comments, and optimization for the C source program and generates an assembly-language source file.

This processes the preprocessing directives in the source program.

Only when the -P option is specified, it outputs the preprocessed file.

This parses the C source program and then converts it to the internal data representation for the compiler.

This optimizes the internal data representation converted from the C source program.

This converts the internal data representation to an assembly-language source program.

This converts the assembly-language source program to machine-language instructions and generates a relocatable object module file.

This links object module files, link directive files, and library files and generates an object file (load module file) executable in the target system.
