ATOM-based lld
|
|
==============
|
|
|
|
Note: this document discuss Mach-O port of LLD. For ELF and COFF,

|
|
|
|
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.
