#14140: Better treatment for dataToTag -------------------------------------+------------------------------------- Reporter: simonpj | Owner: (none) Type: bug | Status: patch Priority: normal | Milestone: Component: Compiler | Version: 8.2.1 Resolution: | Keywords: datacon-tags Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Phab:D3932 Wiki Page: | -------------------------------------+------------------------------------- Comment (by dfeuer): Argh! I should have checked this against HEAD. It seems this was already fixed, in 193664d42dbceadaa1e4689dfa17ff1cf5a405a0. We now rewrite {{{#!hs case dataToTag b of 16# -> True _ -> False }}} to {{{#!hs case b of OtherOS _ -> True _ -> False }}} which has always been good. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14140#comment:9 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
