I'll assume by "it" you mean the thread-state save. I don't believe it is possible; afterall, there may be thread state (which may contain reference to heap objects) sitting in machine registers.
Yes, i mean all the thread pause stuff. I want to understand what is the minimum preparation before we can make FFI calls which doesn't get in GC's way. I believe this helps to reduce GC pause. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13944#comment:9 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
