Linker Tasks

Using Linker commands

Use an assembly language routine named flush_cache (see “The flush_cache Function” in this chapter). You must assemble this routine separately (with the as command) and link it with the main program.

Step 8: Get the addresses of routines and data that are referenced in the module. If the -elinker option was used, the module's header will contain the address of the entry point. The entry point's address is stored in the .exec_entry member of the som_exec_auxhdr structure.

If the module contains multiple routines and data that must be accessed from the main program, the main program can use the nlist(3C) function to get their addresses.

Another approach that can be used is to have the entry point routine return the addresses of required routines and data.

An Example Program

To illustrate dynamic linking concepts, this section presents an example program, dynprog. This program loads an object module named dynobj.o, which is created by dynamically linking two object files file1.o and file2.o (see “file1.o and file2.o”).

The program allocates space for dynobj.o by calling a function named alloc_load_space (see “The alloc_load_space Function” later in this chapter). The program then calls a function named dyn_load to dynamically link and load dynobj.o (see “The dyn_load Function” later in this chapter). Both functions are defined in a file called dynload.c (see “dynload.c”).

As a return value, dyn_load provides the address of the entry point in dynobj.o — in this case, the function foo. To get the addresses of the function bar and the variable counter, the program uses the nlist(3C) function.

•“The Build Environment” shows the example makefile used to create the dynprog program.

•“Source for dynprog” shows the C source code for the dynprog program.

•“Output of dynprog” shows the run time output of the dynprog program.

•“The flush_cache Function” provides example source code in assembly language to flush text from the data cache.
