  New Revision: 47961

  http://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=revision&revision=47961

  Log:
    cont.c: Code cleanup in fiber_switch/fiber_store
    
    Defragment code blocks depending on FIBER_USE_NATIVE in order to make
    the control flow (which is already non-trivial due to nonlocal jumps) in
    each case more comprehensible.
    
    Remove some unreachable code from fiber_switch (we've already excluded
    the case (th->fiber == fibval) at the start of the function).
    
    Remove call to rb_fiber_current which happened a few lines after
    accessing GET_THREAD()->fiber directly (so if that's ever 0 we're
    already screwed).
