#14178: Constant folding bug due to 193664d42dbceadaa1e4689dfa17ff1cf5a405a0 -------------------------------------+------------------------------------- Reporter: bgamari | Owner: (none) Type: bug | Status: new Priority: highest | Milestone: 8.4.1 Component: Compiler | Version: 8.3 Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: None/Unknown Unknown/Multiple | Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- Angerman points out on [[https://mail.haskell.org/pipermail/ghc- devs/2017-September/014572.html|ghc-devs]] a rather frightenin-looking regression involving integer constant folding. It seems that 193664d42dbceadaa1e4689dfa17ff1cf5a405a0 flipped the order of arguments in the constant-folding logic for binary-operations. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14178 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
