#15569: Constant folding optimises 1 into 3 -------------------------------------+------------------------------------- Reporter: snowleopard | Owner: (none) Type: bug | Status: new Priority: highest | Milestone: 8.6.1 Component: Compiler | Version: 8.6.1-beta1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: #9136 | Differential Rev(s): Phab:D5109 Wiki Page: | -------------------------------------+------------------------------------- Comment (by snowleopard): Thanks @sgraf! I think we can proceed with the testing-based solution for now, but I hope we will revisit constant folding rules in future and reimplement them in a more type-safe way. I can volunteer to do that once most of the urgent work on Hadrian is complete. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15569#comment:17 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
