      >
      > Currently it is possible to get into a cycle of

      > where the memory reducer does not free memory.
      >
      > This patch ensures that the memory reducer restarts only if the
      > committed memory increased by sufficient amount after the last run.

      [heap] GCTracer: Record details for incremental marking · 3866975f
      mlippautz authored
      Record details, such as cumulative duration, number of steps, and longest steps
      in IncrementalMarkingDetails which get populated at a single callsite
      (AddScopeSample). Remove member fields that thus become obsolete (unfortunately
      not all of them).
      
      Additional remove some dead code and refactor printing. Printing in a single
      statement allows for using logcat on Android.
      
      This should also address the regression in chromium:640524.

      Filter invalid slots after array trimming. · 017d128b
      ulan authored
      If sweeping is in progress then we need to filter out slots in free space after
      array trimming, because the sweeper will add the free space into free list.
      
      This CL also fixes a bug in SlotSet::RemoveRange.

      New page local store buffer. · bb883395
      ulan authored
      This replaces the global remembered set with per-page remembered sets.
      
      Each page in the old space, map space, and large object space keeps track of
      the set of slots in the page pointing to the new space.
      
      The data structure for storing slot sets is a two-level bitmap, which allows
      us to remove the store buffer overflow and SCAN_ON_SCAVENGE logic.
