#11566: I don't need madvise DONT_NEED -------------------------------------+------------------------------------- Reporter: mfox | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.1 Keywords: | Operating System: Linux Architecture: aarch64 | Type of failure: Incorrect | warning at compile-time Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- Many tests fail because of a warning in rts/posix/OSMem.c unable to decommit memory: function not implemented The reason it says "function not implemented" is that the function madvise(..., DONT_NEED) is not implemented. This is on a stock Ubuntu LTS 14.04 machine. The only interesting thing about it is that it's running on a pre-production armv8 processor with a beta 4.2 guest kernel. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11566 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
