I can get a build to complete just fine if I mangle the ASM in StgCRun.c but haven't made it actually work yet. I'm not sure that 3.4 has full ARM64 support (i.e. works on iOS)... -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/7942#comment:34> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler
