LLVM is a compiler infrasture for several languages. Its is consist of clang (c compiler), the llvm libary (includes llvm-mc the assembler) and lld the linker. The llvm libbary can be used to create several languages like rust.

OS Development with LLVM

LLVM recently has been used is development of BSDs.

One good thing of LLVM, it is cross-compiler by design.

The following command gives the supported architectures

llc -version

As it is as cross compiler by default, clang can called to compile i686-elf for the simply by

clang -target i686-elf
