     5  // Garbage collector: write barriers.
     6  //
     7  // For the concurrent garbage collector, the Go compiler implements
     8  // updates to pointer-valued fields that may be in heap objects by
     9  // emitting calls to write barriers. The main write barrier for
    10  // individual pointer writes is gcWriteBarrier and is implemented in
    11  // assembly. This file contains write barrier entry points for bulk
    12  // operations. See also mwbbuf.go.
