@regehr Nowadays I would recommend reading the mold source code as a replacement for Levine's book. It also has a lot of explanatory text, e.g. the block comment at the top here is probably the best summary of how LTO works: https://github.com/rui314/mold/blob/main/elf/lto-unix.cc
mold/elf/lto-unix.cc at main · rui314/mold

@pervognsen @regehr I will take this chance to shamelessly plug my former colleagues blogs: http://www.linker-aliens.org/

The Solaris Docs for the linker are also a great reference:

@pervognsen @regehr Wow, that really is some outstanding commentary! The kind of thing you hope you'll find every time you open an unfamiliar source file.
