To be a bit more precise `maskAsyncExceptions# j s`, `j` must be an arity-1 join point. Always.
Sure, so in effect we just lift the saturation requirement on arguments of some primops. That makes sense. I just wanted to make sure that we wouldn't be sacrificing even more STG- linting with this change. I can have a swing at implementing this once we feel the design hss converged, if you would like. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14375#comment:5 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
