      "message": "runtime: Bitstring implementation for subtype checking (4/4).\n\nIntegrate the previous CLs into ART Runtime. Subsequent CLs to add\noptimizing compiler support.\n\nUse spare 24-bits from \"Class#status_\" field to\nimplement faster subtype checking in the runtime. Does not incur any extra memory overhead,\nand (when in compiled code) this is always as fast or faster than the original check.\n\nThe new subtype checking is O(1) of the form:\n\n  src \u003c: target :\u003d\n    (*src).status \u003e\u003e #imm_target_mask \u003d\u003d #imm_target_shifted\n\nBased on the original prototype CL by Zhengkai Wu:\nhttps://android-review.googlesource.com/#/c/platform/art/+/440996/\n\nTest: art/test.py -b -j32 --host\nBug: 64692057\nChange-Id: Iec3c54af529055a7f6147eebe5611d9ecd46942b\n"
