This class acts very 0N/A// much like a MutableSpace. We couldn't embed a MutableSpace, though, as 0N/A// it has a considerable number of asserts and invariants that are violated. 0N/A // The shared initialize code invokes this. 0N/A // Filling and flushing. 0N/A // Returns a subregion containing all objects in this space. 0N/A // Boolean querries. 0N/A // Size computations. Sizes are in bytes. 0N/A // Can't assert this, when young fills, we keep the LAB around, but flushed. 0N/A // assert(_state != flushed, "Sanity"); 0N/A // The 'new_top>obj' check is needed to detect overflow of obj+size. 0N/A "checking alignment");
0N/A // Cannot test for this now that we're doing promotion failures 0N/A // assert(_state != flushed, "Sanity"); 0N/A // The 'new_top>obj' check is needed to detect overflow of obj+size. 0N/A "checking alignment");
