      "message": "ART: Register allocation and runtime support for try/catch\n\nThis patch completes a series of CLs that add support for try/catch\nin the Optimizing compiler. With it, Optimizing can compile all\nmethods containing try/catch, provided they don\u0027t contain catch loops.\nFuture work will focus on improving performance of the generated code.\n\nSsaLivenessAnalysis was updated to propagate liveness information of\ninstructions live at catch blocks, and to keep location information on\ninstructions which may be caught by catch phis.\n\nRegisterAllocator was extended to spill values used after catch, and\nto allocate spill slots for catch phis. Catch phis generated for the\nsame vreg share a spill slot as the raw value must be the same.\n\nLocation builders and slow paths were updated to reflect the fact that\nthrowing an exception may not lead to escaping the method.\n\nInstruction code generators are forbidden from using of implicit null\nchecks in try blocks as live registers need to be saved before handing\nover to the runtime.\n\nCodeGenerator emits a stack map for each catch block, storing locations\nof catch phis. CodeInfo and StackMapStream recognize this new type of\nstack map and store them separate from other stack maps to avoid dex_pc\nconflicts.\n\nAfter having found the target catch block to deliver an exception to,\nQuickExceptionHandler looks up the dex register maps at the throwing\ninstruction and the catch block and copies the values over to their\nrespective locations.\n\nThe runtime-support approach was selected because it allows for the\nbest performance in the normal control-flow path, since no propagation\nof catch phi values is necessary until the exception is thrown. In\naddition, it also greatly simplifies the register allocation phase.\n\nConstantHoisting was removed from LICMTest because it instantiated\n(now abstract) HConstant and was bogus anyway (constants are always in\nthe entry block).\n\nChange-Id: Ie31038ad8e3ee0c13a5bbbbaf5f0b3e532310e4e\n"
