#10657: Regression T2497 WAY=optasm: Simplifier ticks exhausted -------------------------------------+------------------------------------- Reporter: thomie | Owner: Type: bug | Status: closed Priority: highest | Milestone: 7.10.2 Component: Compiler | Version: 7.10.2-rc2 Resolution: invalid | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: | typecheck/should_compile/T2497 Blocked By: | Blocking: Related Tickets: | Differential Revisions: -------------------------------------+------------------------------------- Changes (by simonpj): * status: new => closed * resolution: => invalid Comment: This is hardly suprising. Inlining `(==)` we get {{{ {-# RULES "rule 1" forall x y. x == y = y == x #-} }}} So rewriting using the rule yields a new opportunity for using the rule. What did you expect? Re-open if you disagree. Simon -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10657#comment:5 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
