README.md

The New ELF Linker

This directory contains a port of the new PE/COFF linker for ELF.

Overall Design

See COFF/README.md for details on the design. Note that unlike COFF, we do not distinguish chunks from input sections; they are merged together.

Capabilities

This linker can link LLVM and Clang on Linux/x86-64 or FreeBSD/x86-64 "Hello world" can be linked on Linux/PPC64 and on Linux/AArch64 or FreeBSD/AArch64.

Performance

Achieving good performance is one of our goals. It's too early to reach a conclusion, but we are optimistic about that as it currently seems to be faster than GNU gold. It will be interesting to compare when we are close to feature parity.

Library Use

You can embed LLD to your program by linking against it and calling the linker's entry point function lld:🧝:link.

The current policy is that it is your reponsibility to give trustworthy object files. The function is guaranteed to return as long as you do not pass corrupted or malicious object files. A corrupted file could cause a fatal error or SEGV. That being said, you don't need to worry too much about it if you create object files in a usual way and give them to the linker (it is naturally expected to work, or otherwise it's a linker's bug.)
