uh, I should specify that I mean the configure test doesn't.
What precisely is the problem? As far as I can tell Clang has supported both `__atomic_*` and `__sync_* builtins at least as far back as LLVM 3.4. I'm fairly certain that `__sync_*` are supported by `icc` as I have read that this builtins were stolen by `gcc` from `icc`. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14244#comment:12 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
