1ATOM-based lld 2============== 3 4Note: this document discuss Mach-O port of LLD. For ELF and COFF, 5see :doc:`index`. 6 7ATOM-based lld is a new set of modular code for creating linker tools. 8Currently it supports Mach-O. 9 10* End-User Features: 11 12 * Compatible with existing linker options 13 * Reads standard Object Files 14 * Writes standard Executable Files 15 * Remove clang's reliance on "the system linker" 16 * Uses the LLVM `"UIUC" BSD-Style license`__. 17 18* Applications: 19 20 * Modular design 21 * Support cross linking 22 * Easy to add new CPU support 23 * Can be built as static tool or library 24 25* Design and Implementation: 26 27 * Extensive unit tests 28 * Internal linker model can be dumped/read to textual format 29 * Additional linking features can be plugged in as "passes" 30 * OS specific and CPU specific code factored out 31 32Why a new linker? 33----------------- 34 35The fact that clang relies on whatever linker tool you happen to have installed 36means that clang has been very conservative adopting features which require a 37recent linker. 38 39In the same way that the MC layer of LLVM has removed clang's reliance on the 40system assembler tool, the lld project will remove clang's reliance on the 41system linker tool. 42 43 44Contents 45-------- 46 47.. toctree:: 48 :maxdepth: 2 49 50 design 51 getting_started 52 development 53 open_projects 54 sphinx_intro 55 56Indices and tables 57------------------ 58 59* :ref:`genindex` 60* :ref:`search` 61 62__ http://llvm.org/docs/DeveloperPolicy.html#license 63
