      "message": "ARM64: Instruction simplification for array accesses.\n\nHArrayGet and HArraySet with variable indexes generate two\ninstructions on arm64, like\n\n    add temp, obj, #data_offset\n    ldr out, [temp, index LSL #shift_amount]\n\nWhen we have multiple accesses to the same array, the initial `add`\ninstruction is redundant.\n\nThis patch introduces the first instruction simplification in the\narm64-specific instruction simplification pass. It splits HArrayGet\nand HArraySet using the new arm64-specific IR HIntermediateAddress.\nAfter that we run GVN again to squash the multiple occurrences of\nHIntermediateAddress.\n\nChange-Id: I2e3d12fbb07fed07b2cb2f3f47f99f5a032f8312\n"
