      "message": "Class Hierarchy Analysis (CHA)\n\nThe class linker now tracks whether a method has a single implementation\nand if so, the JIT compiler will try to devirtualize a virtual call for\nthe method into a direct call. If the single-implementation assumption\nis violated due to additional class linking, compiled code that makes the\nassumption is invalidated. Deoptimization is triggered for compiled code\nlive on stack. Instead of patching return pc\u0027s on stack, a CHA guard is\nadded which checks a hidden should_deoptimize flag for deoptimization.\nThis approach limits the number of deoptimization points.\n\nThis CL does not devirtualize abstract/interface method invocation.\n\nSlides on CHA:\nhttps://docs.google.com/a/google.com/presentation/d/1Ax6cabP1vM44aLOaJU3B26n5fTE9w5YU-1CRevIDsBc/edit?usp\u003dsharing\n\nChange-Id: I18bf716a601b6413b46312e925a6ad9e4008efa4\nTest: ART_TEST_JIT\u003dtrue m test-art-host/target-run-test test-art-host-gtest\n"
