Yes, it's always a good idea to create a ticket to 
 say what you are doing
 track progress
 give an opportunity for others to comment

|  I've just put my notes here:
|  https://ghc.haskell.org/trac/ghc/wiki/ImprovedArithmeticPrimops
|  
|  Let me know if this page doesn't answer your question.

|  Do I need to create a ticket, too?  In the testsuite, primops live in
|  files like this: testsuite/tests/primops/should_run/T7689.hs
