| ATOM-based lld |
| ============== |
| |
| Note: this document discuss Mach-O port of LLD. For ELF and COFF, |
| see :doc:`index`. |
| |
| ATOM-based lld is a new set of modular code for creating linker tools. |
| Currently it supports Mach-O. |
| |
| * End-User Features: |
| |
| * Compatible with existing linker options |
| * Reads standard Object Files |
| * Writes standard Executable Files |
| * Remove clang's reliance on "the system linker" |
| * Uses the LLVM `"UIUC" BSD-Style license`__. |
| |
| * Applications: |
| |
| * Modular design |
| * Support cross linking |
| * Easy to add new CPU support |
| * Can be built as static tool or library |
| |
| * Design and Implementation: |
| |
| * Extensive unit tests |
| * Internal linker model can be dumped/read to textual format |
| * Additional linking features can be plugged in as "passes" |
| * OS specific and CPU specific code factored out |
| |
| Why a new linker? |
| ----------------- |
| |
| The fact that clang relies on whatever linker tool you happen to have installed |
| means that clang has been very conservative adopting features which require a |
| recent linker. |
| |
| In the same way that the MC layer of LLVM has removed clang's reliance on the |
| system assembler tool, the lld project will remove clang's reliance on the |
| system linker tool. |
