#11566: I don't need madvise MADV_DONTNEED -------------------------------------+------------------------------------- Reporter: mfox | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.1 Resolution: | Keywords: Operating System: Linux | Architecture: aarch64 Type of failure: Incorrect | Test Case: warning at compile-time | Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- @@ -6,1 +6,1 @@ - madvise(..., DONT_NEED) is not implemented. + madvise(..., MADV_DONTNEED) is not implemented. New description: 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(..., MADV_DONTNEED) 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. -- Comment (by rwbarton): If the two-stage allocator isn't working on your system, you can disable it with `configure --disable-large-address-space`. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11566#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
