G1: call CardTable::clear_MemRegion directly

    XMLWordPrintable

Details

    Description

      G1 manages covered heap-region itself, so the guard, `MemRegion mri = mr.intersection(_covered[i]);`, inside `CardTable::clear` is not needed.

      One can call `CardTable::clear_MemRegion` in G1 code.
