Normally, inline expansion is performed for functions within a file. However, using the
-file_inline option of the compiler allows inline expansion to be performed for even inter-file function calling.

[Example]

<a.c>

 func(){

     g();

 }

<b.c>

 g(){

     h();

}

By compiling with the specification of ccrx -inline -file_inline=b.c a.c, calling of function g in a.c is expanded and becomes as follows:

func(){

     h();

}
