Apparatus and Implementation Method of Retargettable Incremental Linking Loarder for Embedded Systems

摘要

PURPOSE: A gradual remote loading device for an embedded system and a method thereof are provided to execute a remote linking for linking target modules in a host and a gradual linking for loading object files one by one. CONSTITUTION: A leader module analyzes linking information necessary for a linking for linking an object file(S110). A linker allocates a target memory space for storing sections based on section information and a section size(S112) and obtains target memory addresses of sections(S114). It is judged whether an entry exists in a symbol table as a definition symbol with respect to each entry of symbol information(S116). It is judged whether the symbol exists in a symbol table as a definition symbol(S124). If the symbol exists in a symbol table as a definition symbol, a rearrangement of an object file is applied(S132). A text and a data section of the rearranged object file are transmitted to a target memory(S134).
