Using llvm and c++

Okay, I know that in order to compile software written in C with llvm instead of gcc, I use this command before compiling:

alias llvmc=gcc

What do I do if I want to compile software written in C++ using llvm instead of g++ ?

Do you mean using C++ instead of C? If so, replace gcc with g++

Forgive me, but I don't think that line does what you say it does. How are you compiling software?

either with makepkg or with yaourt -Sb

I think Trent means that the alias you have makes gcc run when llvm is executed, not the other way around. With

alias gcc=llvm

llvm is run where gcc would normally have been.
If you want llvm to run instead of g++, you can alias g++ just as easily

alias g++=llvm

(I asssume you're using bash?)

Yeah, I'm using bash. I'll try this instead.

Instead of aliasing gcc and c++, I'd use the CC and CXX environmental variables for C and C++ respectively in makepkg.conf. I can't remember off of the top of my head if they need to exported or not.

Well, aliasing is preferred because some software, such as wine and chromium, will not compile under llvm, so I'd prefer to use it explicitly rather than by default.

Anyone tried the LLL tool chain to compile the Linux kernel with LLVM/Clang?

I was planning to try to make a self-hosting (Clang-compiled) AURs for it, but I have not come around to it yet...

It made quite a splash when this guy announced that Linux could be compiled with Clang....
