...since it consumes the modified, normalized metadata as soon as it is "produced". It could also make the MD consistent if it wanted to, but that would be redundant, since it is the only piece of code that directly reads the MD. https://github.com/sanjoy/llvm/blob/parallel-md/lib/Analysis/ParallelizationMetadata.cpp is basically an implementation of this "squashed" pass. It provides an interface to the MD and this interface normalizes the MD before exposing it. Thanks! -- Sanjoy Das http://playingwithpointers.com

In case it doesn't it doesn't matter what the metadata looks like anyway. In case it does, we have the ParallelizationMetadata pass to present a consistent view of the metadata; how does it matter how the metadata actually looks like? I think it will be helpful if you could illustrate your point with an example. To be clear, I'm not saying that dropping metadata is unreasonable; but am trying to figure out what the c...
