This chapter will describe the functions of the Linker lk62.

6.1 Functions

The Linker lk62 is a software that generates executable object files. It provides the following functions:
•Puts together multiple object modules to create one executable object file.
•Resolves external reference from one module to another.
•Relocates relative addresses to absolute addresses.
•Delivers debugging information, such as line numbers and symbol information, in the object file
created after linking.
•Capable of outputting a link map file, symbol file, absolute list file and a cross reference file.
•Automatic page correction function (insertion/removal/correction of the pset instruction) for branch
instructions.

6.2.1 Input Files

Relocatable object file
File format: Binary file in IEEE-695 format
File name: <File name>.o (A path can also be specified.)
Description: Object file of individual modules created by the assembler.
Linker command file
File format: Text file
File name: <File name>.cm (A path can also be specified.)
Description: File to specify the linker options. This makes it possible to reduce typing in a command
line. This file is dispensable if all start-up options can be input in a command line.
ICE parameter file ∗ This file must always be specified.
File format: Text file
File name: <File name>.par (A path can also be specified.)
Description: File to specify the memory mapping and unsupported instruction information of each
S1C62 Family model. This file is supplied in the development tools for each model and
commonly used with the debugger, HEX converter and disassembler.
