#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 YitzGale): Hmm, by requiring GCC 4.7, this bans GHC from RHEL/CentOS 6, which uses GCC 4.4. That OS will be supported until the end of 2020, and will continue to be used fairly widely in the enterprise until close to then. Can this requirement be avoided at least for x86, amd64, and llvm builds, where it isn't actually needed? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14244#comment:7 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
