</span>To be honest, the MSAN is still failing on other AArch64 tests:<br>

Failing Tests (8):<br>
    LLVM :: CodeGen/AArch64/arm64-2012-01-11-ComparisonDAGCrash.ll<br>
    LLVM :: CodeGen/AArch64/arm64-andCmpBrToTBZ.ll<br>
    LLVM :: CodeGen/ARM/2009-06-04-MissingLiveIn.ll<br>
    LLVM :: CodeGen/ARM/2009-09-13-InvalidSubreg.ll<br>
    LLVM :: CodeGen/ARM/2010-06-21-LdStMultipleBug.ll<br>

    LLVM :: Transforms/SimplifyCFG/branch-fold.ll<br>
<br>
Which are very similar to the ones in the build that had your patch. I<br>
think you can re-commit your patch as it was, and we should look for<br>
the source of the uninitialised variables elsewhere.<br>
