I was working on an ELF linker in Scheme recently, and wanted to re-read some of Ian Lance Taylor's 20-part series on ELF linkers and linking. In a brief search of the tubes, a list of the articles didn't come up, so perhaps this short and sweet list will make some future web searcher happy.
The list: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20
They articles are well-written and fascinating, so don't click unless you have a few hours to burn.
