Phoronix: LLVM's Clang Now Can Build Itself

The Clang compiler that provides a C/Object-C/C++ compiler atop the Low-Level Virtual Machine (LLVM) is now self-hosting, which means Clang can now be used to compile itself. The LLVM developers reached this important milestone where LLVM/Clang can now be used to build Clang with working resulting binaries that can even go on to build another copy of Clang as well. The short announcement of this compiler achievement for LLVM/Clang can be read on the LLVM blog...

It was able to "build itself" previously in the sense of completing a compile, but it wasn't self-hosting because the C++ support was still too broken for the built compiler to work properly. It's pretty amazing to see how far Clang's C++ support has come.

I guess that means that LLVM is completed now? Or at least reached the point of fully working reliably for now?

let's see.. gcc has been able to build itself for decades. Is it complete yet?

LLVM has reached an important milestone, but there's still source code out there it doesn't compile, there's still optimizations to make, features to add etc.

No C++ compiler will *ever* be complete

Wait 'til I finish writing my perfect compiler-compiler.

Wow, this is a great step forward. Looks like it's time to do some tests with Clang again, hopefully optimizations like LTO (link time optimization) are not exclusive to the OSX platform anymore.

Hm?

I think he is speaking about clang, not gcc.
