      "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"

      "message": "Fix access to long/double stack values from debugger\n\nLong and double values live in a pair of DEX registers. When we compile DEX\ncode with the Quick compiler, a DEX register either lives in the stack or is\npromoted to a physical register. In the case of a pair of DEX registers, the\nQuick compiler assumes both registers live in the same \"area\": both live in\nthe stack or both are promoted to physical registers.\n\nFrom the debugger, we used to access these values by reading/writing each DEX\nregister separately. However, this does not work when only one DEX register of\na pair is promoted and the other lives in the stack. In this case, the compiled\ncode reads from/writes to the stack only.\n\nTo fix that, the debugger must follow the same rule than the Quick compiler: if\nboth DEX registers are promoted, read/write them from/to physical registers,\notherwise read/write them from/to the stack. We add StackVisitor:GetVRegPair and\nStackVisitor:SetVRegPair for this purpose.\n\nWe also follow the same rule when deoptimizing. However we need to do that only\nwhen we know two consecutive DEX registers are part of a pair (long or double).\nWe know that thanks to the verifier.\n\nBug: 15527793\nChange-Id: I04812285ff26ef0129f39792a1cf776f3591ca2d\n"

It does this by using sigaction to trap SIGSEGV and when triggered\nmakes sure it\u0027s in compiled code and if so, sets the return\naddress to the entry point to throw the exception.\n\nIt also uses this signal mechanism to determine whether to check\nfor thread suspension.  Instead of the compiler generating calls\nto a function to check for threads being suspended, the compiler\nwill now load indirect via an address in the TLS area.  To trigger\na suspend, the contents of this address are changed from something\nvalid to 0.  A SIGSEGV will occur and the handler will check\nfor a valid instruction pattern before invoking the thread\nsuspension check code.\n\nIf a user program taps SIGSEGV it will prevent our signal handler\nworking.  This will cause a failure in the runtime.\n\nThere are two signal handlers at present.  You can control them\nindividually using the flags -implicit-checks: on the runtime\ncommand line.  This takes a string parameter, a comma\nseparated set of strings.  Each can be one of:\n\nnone        switch off\nnull        null pointer checks\nsuspend     suspend checks\nall         all checks\n\nSo to switch only suspend checks on, pass:\n-implicit-checks:suspend\n\nThere is also -explicit-checks to provide the reverse once\nwe change the default.\n\nFor dalvikvm, pass --runtime-arg -implicit-checks:foo,bar\n\nThe default is -implicit-checks:none\n\nThere is also a property \u0027dalvik.vm.implicit_checks\u0027 whose value is the same\nstring as the command option.  The default is \u0027none\u0027.  For example to switch on\nnull checks using the option:\n\nsetprop dalvik.vm.implicit_checks null\n\nIt only works for ARM right now.\n\nBumps OAT version number due to change to Thread offsets.\n\nBug: 13121132\nChange-Id: If743849138162f3c7c44a523247e413785677370\n"

A\nlistener is now responsible for configuring the appropriate stubs.\n- The method tracing listener installs instrumentation entry/exit stubs or\nthe interpreter depending on the accuracy of events we want (controlled by\nkDeoptimizeForAccurateMethodEntryExitListeners).\n- The debugger registers itself as an instrumentation listener but does not\nmodify methods entrypoints. It only does this on demand when deoptimizing one\nmethod or all the methods.\n\nThe selective deoptimization is used for breakpoint only. When a breakpoint is\nrequested, the debugger deoptimizes this method by setting its entrypoint to\nthe interpreter stub. As several breakpoints can be set on the same method, we\ndeoptimize only once. When the last breakpoint on a method is removed, we\nreoptimize it by restoring the original entrypoints.\n\nThe full deoptimization is used for method entry, method exit and single-step\nevents. When one of these events is requested, we force eveything to run with\nthe interpreter (except native and proxy methods). When the last of these\nevents is removed, we restore all methods entrypoints except those which are\ncurrently deoptimized.\n\nDeoptimizing a method requires all mutator threads be suspended in order to\nwalk each thread\u0027s stack and ensure no code is actually executing while we\nmodify methods entrypoints. Suspending all the threads requires to not hold\nany lock.\nIn the debugger, we deoptimize/undeoptimize when the JDWP event list changes\n(add or remove a breakpoint for instance). During the update, we need to hold\nthe JDWP event list lock. This means we cannot suspend all the threads at this\ntime.\nIn order to deal with these constraints, we support a queue of deoptimization\nrequests. When an event needs selective/full deoptimization/undeoptimization,\nwe save its request in the queue. Once we release the JDWP event list lock, we\nsuspend all the threads, process this queue and finally resume all the threads.\nThis is done in Dbg::ManageDeoptimization. Note: threads already suspended\nbefore doing this remain suspended so we don\u0027t \"break\" debugger suspensions.\n\nWhen we deoptimize one method or every method, we need to browse each thread\u0027s\nstack to install instrumentation exit PC as return PC and save information in\nthe instrumentation stack frame. Now we can deoptimize multiple times during\nthe execution of an application, we need to preserve exisiting instrumentation\nframes (which is the result of a previous deoptimization).

These are Classes, Methods, and Fields.\n\nBump pointer spaces are a new type of continuous alloc space which have\nno lock in the allocation code path. When you allocate from these it uses\natomic operations to increase an index. Traversing the objects in the bump\npointer space relies on Object::SizeOf matching the allocated size exactly.\n\nRuntime changes:\nJNI::GetArrayElements returns copies objects if you attempt to get the\nbacking data of a movable array. For GetArrayElementsCritical, we return\ndirect backing storage for any types of arrays, but temporarily disable\nthe GC until the critical region is completed.\n\nAdded a new runtime call called VisitObjects, this is used in place of\nthe old pattern which was flushing the allocation stack and walking\nthe bitmaps.\n\nChanged image writer to be compaction safe and use object monitor word\nfor forwarding addresses.\n\nAdded a bunch of added SIRTs to ClassLinker, MethodLinker, etc..\n\nTODO: Enable switching allocators, compacting on background, etc..\n\nBug: 8981901\n\nChange-Id: I3c886fd322a6eef2b99388d19a765042ec26ab99\n"
