===Linker===
The lld subproject is an attempt to develop a built-in, platform-independent [[linker (computing)|linker]] for LLVM.<ref name="lld-home-page">{{cite web|title=lld - The LLVM Linker|url=http://lld.llvm.org/|publisher=The LLVM Project|access-date=May 10, 2017}}</ref> lld aims to remove dependence on a third-party linker. {{As of|2017|05}}, lld supports [[Executable and Linkable Format|ELF]], [[PE/COFF]], [[Mach-O]], and [[WebAssembly]]<ref>{{cite web|url=https://lld.llvm.org/WebAssembly.html|title=WebAssembly lld port}}</ref> in descending order of completeness. lld is faster than both flavors of [[GNU ld]].{{citation needed|date=December 2021}}

Unlike the GNU linkers, lld has built-in support for [[link-time optimization]] (LTO). This allows for faster code generation as it bypasses the use of a linker plugin, but on the other hand prohibits interoperability with other flavors of LTO.<ref>{{cite web |title=42446 – lld can't handle gcc LTO files |url=https://bugs.llvm.org/show_bug.cgi?id=42446 |website=bugs.llvm.org}}</ref>
