Each GC // is free to decide the internal structure and contents of this // area. It is represented as a 64-bit aligned opaque blob to // avoid circular dependencies between Thread and all GCs. For // the same reason, the size of the data area is hard coded to // provide enough space for all current GCs. Adjust the size if // needed, but avoid making it excessively large as it adds to // the memory overhead of creating a thread. // // Use Thread::gc_data<T>() to access the data, where T is the // GC-specific type describing the structure of the data. GCs // should consider placing frequently accessed fields first in // T, so that field offsets relative to Thread are small, which // often allows for a more compact instruction encoding. typedef uint64_t GCThreadLocalData[19]; // 152 bytes #endif // SHARE_GC_SHARED_GCTHREADLOCALDATA_HPP
