I figured that it'd be getting rid of the point of the test since it "defines" how the functions should behave.I'm now digging into how/what instructions are emitted by the popCount PrimOps. Also, it'd be nice if someone to clear up why this [https://github.com/ghc/testsuite/commit/14619423995f69a76061b5f84025188ca2fe... patch] was needed. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/7684#comment:12 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
