lld is the linker in the LLVM family of projects. + It is intended to be a high-performance linker and supports + the ELF, COFF, and Mach-O object + formats. Where possible, lld maintains command-line + and functional compatibility with the existing + GNU BFD ld and gold linkers. However, the + authors of lld are not constrained by strict + compatibility where it would hamper performance or desired + functionality.

+ +

Over the last quarter, the lld project implemented + version script support sufficient to handle the &os; base + system. This is an important milestone on the path to having + lld as a viable system linker.

+ +

lld still lacks comprehensive linker script + expression evaluation support, and therefore cannot yet be + used to link the &os; kernel.
