@vgvassilev , I am testing this change ( along with fb3367f ) here https://github.com/cms-sw/root/pull/160/files but root still failed to build for ppc64le |

@smuzaffar, the jenkins link does not open for me. Can you attach the log here. |

The build works for me -- |

@vgvassilev did you build root master or root v6.24 plus your change and fb3367f ? |

if you have cms account then you should be able to access the logs. It fails (segmentation faults) at the end again with error |

@smuzaffar, I am on v6-24-00-patches with the patches you mentioned. |

@vgvassilev , this looks good ( I have tested it here cms-sw/cmsdist#7445 ) . Can you please back port it to v6.24 branch too? |

There was a problem hiding this comment.
I can't claim that I fully understand what's going on here (had to look up TOCs, https://reverseengineering.stackexchange.com/questions/21944/powerpc-toc-and-sda#21962 if you're interested), but LGTM.
@vgvassilev can you please update the commit message to point to https://reviews.llvm.org/D91983, which was the original review? The other is just the (attempted) backport to LLVM 10.
