#7447: Stale .hi files affect compilation. ------------------------------------------------+--------------------------- Reporter: int-e | Owner: Type: bug | Status: closed Priority: high | Milestone: 7.6.2 Component: Compiler | Version: 7.6.1 Resolution: fixed | Keywords: Os: Linux | Architecture: x86_64 (amd64) Failure: Incorrect warning at compile-time | Difficulty: Unknown Testcase: | Blockedby: Blocking: | Related: ------------------------------------------------+--------------------------- Changes (by parcs): * status: new => closed * resolution: => fixed Comment: This is what I get with current HEAD: {{{

echo 'module Peaker(L(..)) where{ data V = V {-# UNPACK #-} !L; data L = L V }' > Peaker.hs ghc -fforce-recomp -O1 Peaker.hs [1 of 1] Compiling Peaker ( Peaker.hs, Peaker.o ) ghc -fforce-recomp -O1 Peaker.hs [1 of 1] Compiling Peaker ( Peaker.hs, Peaker.o )

}}} The warning is no longer produced at all, which I think is the correct behavior because there is no reason that L shouldn't be able to get unpacked into V. So I think it's OK to close the ticket. -- Ticket URL: http://hackage.haskell.org/trac/ghc/ticket/7447#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
