      "message": "Compress the Dex register maps built by the optimizing compiler.\n\n- Replace the current list-based (fixed-size) Dex register\n  encoding in stack maps emitted by the optimizing compiler\n  with another list-based variable-size Dex register\n  encoding compressing short locations on 1 byte (3 bits for\n  the location kind, 5 bits for the value); other (large)\n  values remain encoded on 5 bytes.\n- In addition, use slot offsets instead of byte offsets to\n  encode the location of Dex registers placed in stack\n  slots at small offsets, as it enables more values to use\n  the short (1-byte wide) encoding instead of the large\n  (5-byte wide) one.\n- Rename art::DexRegisterMap::LocationKind as\n  art::DexRegisterLocation::Kind, turn it into a\n  strongly-typed enum based on a uint8_t, and extend it to\n  support new kinds (kInStackLargeOffset and\n  kConstantLargeValue).\n- Move art::DexRegisterEntry from\n  compiler/optimizing/stack_map_stream.h to\n  runtime/stack_map.h and rename it as\n  art::DexRegisterLocation.\n- Adjust art::StackMapStream,\n  art::CodeGenerator::RecordPcInfo,\n  art::CheckReferenceMapVisitor::CheckOptimizedMethod,\n  art::StackVisitor::GetVRegFromOptimizedCode, and\n  art::StackVisitor::SetVRegFromOptimizedCode.\n- Implement unaligned memory accesses in art::MemoryRegion.\n- Use them to manipulate data in Dex register maps.\n- Adjust oatdump to support the new Dex register encoding.\n- Update compiler/optimizing/stack_map_test.cc.\n\nChange-Id: Icefaa2e2b36b3c80bb1b882fe7ea2f77ba85c505\n"
