I&#x27;ve been told that the LLVM branch I linked to is &#x27;the most wrong branch you possibly could have linked to&#x27;.<p>This is the right one: <a href="https:&#x2F;&#x2F;github.com&#x2F;rust-lang&#x2F;llvm&#x2F;tree&#x2F;rust-llvm-2016-03-13" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;rust-lang&#x2F;llvm&#x2F;tree&#x2F;rust-llvm-2016-03-13</a><p>Patches are mostly backported from upstream or optimizations.
