Dead HTML Link in GHC/HsToCore/PmCheck
Dead HTML Link in Codebase
On line 78, of compiler/GHC/HsToCore/PmCheck.hs
there is a dead link to the paper, "GADTs Meet Their Match: Pattern-matching Warnings That Account for GADTs, Guards, and Laziness" :
http://people.cs.kuleuven.be/~george.karachalias/papers/p424-karachalias.pdf
Proposed change
If it's not possible to fix the original link, a copy of the same paper is available at the following url:
https://www.microsoft.com/en-us/research/wp-content/uploads/2016/08/gadtpm-acm.pdf
Within the codebase, Microsoft hosted versions of papers are used for a few other papers as well.
