mold: A Modern Linker
Rui Ueyama - Thu 23 June 2022
Talk description
mold is a faster drop-in replacement for existing Unix linkers. It is several times faster than the LLVM lld linker, the second-fastest open-source linker which was created a few years ago. mold is designed to increase developer productivity by reducing build time, especially in rapid debug-edit-rebuild cycles.Outline of the talk:
- What is the linker?
- Why does the linker's speed matter?
- Performance comparison of mold, LLVM lld and GNU gold
- Why is mold so fast?
- Hints on writing faster programs
