Compiler_builtins - LLVM ERROR: Cannot select

[Freddyfux]

I want to use msp430-quickstart and got this compiler-builtins error:

I have no clue what this means and how to fix it. Maybe someone can help me. I am working with a Windows engine.

Duplicate of #441. It is fixed in compiler-builtins 0.1.55. I am not sure if rustc has already updated to it. You can try updating rustc.

@Freddyfux There was no way to work around the "cannot select" without fixing compiler-builtins. So I didn't update the quickstart, knowing I would get a fix in semi-shortly, and hoped nobody else would notice :P. Apparently not...
