Meet lld - The LLVM Linker

lld is a new set of modular code for creating linker tools.

                   End-User Features:

• Compatible with existing linker options
• Reads standard Object Files (e.g. ELF, Mach-O, PE/COFF)
• Writes standard Executable Files (e.g. ELF, Mach-O, PE)
• Fast link times
• Minimal memory use
• 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
• Internal linker model can be dumped/read to a new native format
• Native format designed to be fast to read and write
• Additional linking features can be plugged in as “passes”
• OS specific and CPU specific code factored out
