#10433: Fix load/store barriers in pre-ARMv7 builds -------------------------------------+--------------------------------- Reporter: thoughtpolice | Owner: Type: bug | Status: new Priority: high | Milestone: 7.12.1 Component: Runtime System | Version: Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: arm Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: #10244 | Differential Revisions: -------------------------------------+--------------------------------- Changes (by rwbarton): * owner: rwbarton => Comment: I won't be getting around to fixing this any time soon. The easy, conservative thing to do would be to set NOSMP if arm_HOST_ARCH_PRE_ARMv7 is defined. The fancy way would be to detect at runtime whether we are on a system that supports memory barriers and patch them in if so (like Linux's altinstructions). Probably too fancy... -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10433#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
