Linker and Utilities
5.1 Introduction
HI-TECH C incorporates a relocating assembler and linker to permit separate compilation of C
source files. This means that a program may be divided into several source files, each of which
may be kept to a manageable size for ease of editing and compilation, then each source file may be
compiled separately and finally all the object files linked together into a single executable program.
instances it will not be necessary to use the linker directly, as the compiler driver will automatically
invoke the linker with all necessary arguments. Using the linker directly is not simple, and should
be attempted only by those with a sound knowledge of the compiler and linking in general.
arguments constructed by the compiler driver, and modify them as appropriate. This will ensure that
the necessary startup module and arguments are present.
several different processors. Not all features described in this chapter are applicable to all compilers.
5.2 Relocation and Psects
The fundamental task of the linker is to combine several relocatable object files into one. The
object files are said to be relocatable since the files have sufficient information in them so that any
references to program or data addresses (e.g. the address of a function) within the file may be
adjusted according to where the file is ultimately located in memory after the linkage process. Thus
the file is said to be relocatable. Relocation may take two basic forms; relocation by name, i.e.
This chapter describes the theory behind and the usage of the linker. Note however that in most
If it is absolutely necessary to use the linker directly, the best way to start is to copy the linker
Note also that the linker supplied with HI-TECH C is generic to a wide variety of compilers for
