LLVM is a compiler infrastructure for several languages. It consists of clang as the C compiler, the LLVM library (includes llvm-mc as the assembler) and lld as the linker. The LLVM library can be used to create several languages like Rust.
OS Development with LLVM
LLVM recently has been used in development of BSDs.
One good thing about LLVM is that it is cross-compiler by design.
The following command gives the supported architectures
As it is a cross compiler by default, clang can called to compile i686-elf for the simply by
clang -target i686-elf
To link the object files, simply use
ld.lld, as for LLD, architectures doesn't matter.
