1.2 Program Development Procedure by C Compiler

Product (program) development by the C compiler requires a linker, which unites together object module files

created by the compiler, a librarian, which creates library files, and a debugger, which locates and corrects bugs

(errors or mistakes) in each created C source program.

The software required in connection with this C compiler is shown below.

•

Editor .......................................... for source module file creation

•

RA78K4 assembler package

Assembler .................................. for converting assembly language into machine language

Object converter ......................... for conversion to HEX-format object module files

Linker.......................................... for linking object module files

Librarian ..................................... for creating library files

•

Debugger (for 78K/IV) ................ for debugging C source module files

The product development procedure by the C compiler is as shown below.

<1> Divides the product into functions.

<2> Creates a C source module for each function.

<3> Translates each C source module.

<4> Registers the modules to be used frequently in the library.

<5> Links object module files.

<6> Debugs each module.

<7> Converts object modules into HEX-format object files.

As mentioned earlier, this C compiler translates (compiles) a C source module file and creates an object module

file or assembler source module file.

By manually optimizing the created assembler source module file and

embedding it into the C source, efficient object modules can be created. This is useful when high-speed processing

is a must or when modules must be made compact.
