Internal Linker

Good information about linkers and loaders can be found in the book Linkers and Loaders at http://www.iecc.com/linker/

Steps

• Get familiar with the fpc sources
• Analyse what is available in the fpc sources. A couple of years ago a basic linker for go32v2 was already working.
• Start coding, the first thing to add is a scriptable memory/file layout, like the ld-scripts.
• Add PE coff support
• Add static ELF support
• Add shared ELF support
• Add optimizations for smartlinking
• Add internal object format
• Keep an eye on memory usage and overall speed.
