/* Write barrier (WB) interfaces:
* - OBJ_WRITE(a, slot, b): WB for new reference from `a' to `b'.
* Write `b' into `*slot'. `slot' is a pointer in `a'.
* - OBJ_WRITTEN(a, oldv, b): WB for new reference from `a' to `b'.
* This doesn't write any values, but only a WB declaration.
* `oldv' is replaced value with `b' (not used in current Ruby).
*
* NOTE: The following core interfaces can be changed in the future.
* Please catch up if you want to insert WB into C-extensions
* correctly.
