Well, one bug is that in `emitPopCntCall` we don't cast the argument to

The `-dcmm-lint` should catch it, because the argument width isn't the same as the primop is expecting, but the Cmm linter doesn't check the arguments of prim calls (that's another bug). How would one cast the argument in the `emitPopCntCall`? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/7684#comment:44 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
