Ian Lance Taylor c8a47c4877 runtime: avoid write barriers when calling deferred function ... 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.
