Remove CardTable::_guard_region

XMLWordPrintable

    • gc
    • b15

      This field is for catching card-table out-of-range access, and used by Serial and Parallel.

      It requires reserving one extra OS page, but its value is limited -- haven't had any out-of-range access in this area for the past 1 year.

      Therefore, one can remove it to match G1.
