    • runtime: make NumGoroutine wait for system goroutines to register · 47f68dc2 
          
    In libgo system goroutines register themselves after they start.
    That means that there is a small race between the goroutine being
    seen by the scheduler and the scheduler knowing that the goroutine
    is a system goroutine. That in turn means that runtime.NumGoroutines
    can overestimate the number of goroutines at times.
    
    This patch fixes the overestimate by counting the number of system
    goroutines waiting to start, and pausing NumGoroutines until those
    goroutines have all registered.
    
    This is kind of a lot of mechanism for this not very important
    problem, but I couldn't think of a better approach.
    
    The test for this is TestNumGoroutine in runtime/proc_test.go.
    The test is not currently run, but it will be soon.

    • runtime: don't assume that _ = *s will panic if s is nil · c016fd32 
          
    With the gc toolchain apparently
            var s *string
            _ = *s
    is enough to panic with a nil pointer dereference. The gccgo compiler
    will simply discard the dereference, which I think is a reasonable and
    acceptable optimization. Change the tests to use an exported variable
    instead. The tests are not currently run, but they will be with a
    later patch to gotools.

    • runtime: change some stack fields to uintptr · 3b0ddadf 
          
    Because of how gccgo implements cgo calls, the code in dropm may not
    have any write barriers.  As a step toward implementing that, change
    the gcstack, gcnextsegment, and gcnextsp fields of the g struct to
    uintptr, so that assignments to them do not require write barriers.
    The gcinitialsp field remains unsafe.Pointer, as on 32-bit systems
    that do not support split stack it points to a heap allocated space
    used for the goroutine stack.
    
    The test for this is runtime tests like TestCgoCallbackGC, which are
    not run today but will be run with a future gotools patch.

    • runtime: avoid write barriers when calling deferred function · c8a47c48 
          
    Calling a deferred function currently requires changing from a uintptr
    to the function code to a Go function value. That is done by setting
    the value of a func local variable using unsafe.Pointer. The local
    variable will always be on the stack. Adjust the code that sets the
    local variable to avoid generating a write barrier.
    
    A write barrier is never needed here. Also, for deferreturn, we must
    avoid write barriers entirely when called from a cgo function; that
    requires more than just this, but this is a start.
    
    The test for this is runtime tests that use the go tool; these are not
    currently run, but they will be in the future.

    • runtime: rename _defer struct _panic field to panicStack · b92e4dff 
          
    The gc version of the _defer struct has a _panic field that has a
    completely different meaning. We are going to want that bring that new
    meaning into the gofrontend to improve panic reports with nested
    panic calls. Simplify that by first renaming the existing _panic field.
