I originally wrote this code for cabal and tested it on all platforms back then.

[GHC] #9440: Buggy binder swap in occurrence analysis

#9440: Buggy binder swap in occurrence analysis -------------------------------------+------------------------------------- Reporter: afarmer | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.8.3 Keywords: | Operating System: Architecture: Unknown/Multiple | Unknown/Multiple Difficulty: Unknown | Type of failure: Blocked By: | None/Unknown Related Tickets: | Test Case: | Blocking: | Differential Revisions: -------------------------------------+------------------------------------- Occurrence analysis on case alternatives performs a "binder swap", whereby occurrences of the scrutinee in alternative RHSs are replaced by the case binder when the scrutinee is a variable or a casted variable. {{{ case x of w C vs -> rhs === case x of w C vs -> let x = w in rhs }}} This should check two conditions, mentioned in Note [Binder swap]. (a) x is free in `C vs -> rhs`, otherwise one of two bad things happen: 1) it is pointless 2) new binding of x would capture one of the alternative binders (vs) (b) w is not in vs Neither of these conditions is actually being checked. Additionally, the binder swap happens in the presence of casts: {{{ case x |> co of w C vs -> rhs === case x |> co of w C vs -> let x = w |> sym co in rhs }}} But the analysis is not returning usage info for free coercion variables in co. Condition (a) bit us in HERMIT when running `occurAnalyseExpr` on the following expression resulting from unfolding nested calls to `fst`: {{{ case x_X11b of wild_a3YB (,) x_a3YD ds1_a3YE -> case x_a3YD of wild_a3YB (,) x_a3YD ds1_a3YE -> x_a3YD }}} The analysis would erroneously result in: {{{ case x_X11b of wild_a3YB (,) x_a3YD ds1_a3YE -> case x_a3YD of wild_a3YB (,) x_a3YD ds1_a3YE -> let x_a3YD = wild_a3YB in x_a3YD }}} which is clearly Not Good. Patch forthcoming via Phabricator. Unfortunately, I don't have a good test case that doesn't involve HERMIT, but can confirm this patch fixes the problem above. -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/9440> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler
