CHAPTER 12: LINKER
(Common explanation for all versions)
Chapter 12 Linker
This chapter describes the functions of the Linker lk33.
12.1 Functions
The Linker lk33 (hereafter called the "lk33") is a software that generates executable object files. It provides the
following functions:
Beginning from lk33 Ver. 3.0, the linker allows multiple sections of the same type to be handled as a single block.
As a result, multiple sections can be mapped into a virtual or shared area, and numerous other functional
enhancements over the previous versions have been provided. Note that these functional enhancements require
newly incorporated block setup commands, and are not compatible with the conventional selection placement
commands. Specifying the -v3 command enables Ver. 3.0 commands; when unspecified, sections are processed
using the conventional command architecture. Therefore, the linker command files created with the earlier
versions of the linker can be used without modifications.
In this chapter, the linker commands and link operations are described separately for Ver. 2.1 and earlier versions
and Ver. 3.0. For processing using the conventional command architecture, refer to Section 12.5, "Link
Processing in lk33 Ver. 2.1 or earlier". For processing using the new command architecture, refer to Section 12.6,
"Link Processing in lk33 Ver. 3.0". Other explanations in this chapter apply to both old and new versions.
12.2 Input/Output Files
