#14244: ghc-prim: hs_atomicread* and hs_atomicwrite* missing barriers -------------------------------------+------------------------------------- Reporter: trommler | Owner: trommler Type: bug | Status: closed Priority: high | Milestone: 8.4.1 Component: Prelude | Version: 8.2.1 Resolution: fixed | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Incorrect result | Unknown/Multiple at runtime | Test Case: Blocked By: | Blocking: Related Tickets: #12537 | Differential Rev(s): Phab:D4009 Wiki Page: | -------------------------------------+------------------------------------- Comment (by trommler): If that helps, GCC 4.7 and up is only a build-time requirement. There are newer versions of GCC available for RHEL and CentOS as part of the Red Hat Developer Toolset for instance. In the case of the LLVM-backend you need a fairly recent (and IIRC an exact) version both at build-time and at run-time. If you are going to install LLVM then you could use clang that comes with it. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14244#comment:8 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
