[LLVMdev] Fwd: Re: [PATCH] [TABLEGEN] Do not crash on intrinsics with names longer than 40 characters

Hi Manuel,

Here's another commit authored through the web interface where no 
discussion or reviewership information is apparent on the mailing list.

All we see in cases like this are a few unthreaded list posts by the 
original author followed by an SVN revision number:

http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20140714/226166.html

For any patch that's submitted for review, especially in a core module 
like tablegen, I think it's worth putting the review discussion in a 
public place so we can keep track.

If you look at the phab review, it's the same there. The only changes
on the review actually went to the mailing list.

Does that mean no review comments were posted in the first place, or did 
they go missing?

Sure, Manuel asked to forward incidents involving the web review system 
instead of directly checking in the individual contributor as we were 
doing before.
