#13614: Rewrite rules not applied exhaustively when simplifying from plugin -------------------------------------+------------------------------------- Reporter: nomeata | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: GHC API | Version: 8.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by nomeata):
I wonder if you have ensured that GHC.Base is loaded? If the interface is not loaded, GHC won't see the rule.
Yes, `GHC.Base` is loaded. I was under the impression that (non-orphan) rules are attached to the `ID`, so should it matter? Or is that only true for locally defined rules? Or is `GHC.Base` special in that matter? In the above plugin code, the result of `getRuleBase` is indeed empty, and so is `mg_rules guts`. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13614#comment:7 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
