#7860: Add more bit fiddling functions to 'integer-gmp' --------------------------------+------------------------------------------- Reporter: lebedev | Owner: Type: feature request | Status: new Priority: normal | Milestone: Component: libraries (other) | Version: 7.6.3 Resolution: | Keywords: gmp Os: Unknown/Multiple | Architecture: Unknown/Multiple Failure: None/Unknown | Difficulty: Unknown Testcase: | Blockedby: Blocking: | Related: #3489 --------------------------------+------------------------------------------- Changes (by igloo): * status: patch => new Comment: Thanks for the patch. However, it's not clear to me that this won't actually cause performance regressions. For example, this: {{{ clearBitInteger j@(S# _) i = clearBitInteger (toBig j) i }}} means that `clearBit` will always unnecessarily promote small integers to large integers. -- Ticket URL: http://hackage.haskell.org/trac/ghc/ticket/7860#comment:6 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
