Chapter 6 Using Linker
6.1

Purpose of This Chapter

This chapter explains how to use all the options provided by the linker. The linker reads relocatable
object files output by the assembler, outputs an executable format file, and if specified by option
outputs a map file containing link information. If optimization was specified at the assembly stage, the
linker will also adjust code such that it outputs optimal code for conditional and unconditional branch
instructions. In addition, the linker also resolves forward references.
For programs in section address format, the start address of each section is specified when linking. The
linker links relocatable object files by section in the order specified by the link command, and outputs
an executable format file.
