      "message": "Codegen support for debugger\n\nAdd the ability to generate code with support for debugging.\nThis involves generating a callout to an equivalent of the\nold \"updateDebugger()\" before each Dalvik opcode, method\nentry and method exit.\n\nThe added code is fairly compact - 8 bytes per Dalvik opcode,\nplus 4 additional bytes per safe point.\n\nI dislike the idea of always making this call, so I\u0027m reusing\nthe dedicated register rSUSPEND to hold the address of the callout.\nrSUSPEND is normally used to reduce the frequency of full suspend\nchecks, but when debugging this isn\u0027t necessary - allowing\nus to resuse this register to hold the address of the callout.\nIf it is non-null we make the callout, otherwise we continue.  I refresh\nthis register from a slot in the Thread structure on method entry\nand also following the return of taken suspend checks.  In this way,\nthe debugger has the ability to control updates on a per-thread basis,\nand the performance penalty is greatly reduced for threads that don\u0027t\nhave any pending debugger requests.  Once the debugger attaches,\nit would suspend all threads, walk through the thread list, set\nthread-\u003epUpdateDebuggerFromCode to art_update_debugger and then\nturn everything loose.\n\nOne thing I\u0027m not doing, though, is debugger updates before and after\ncalls to native methods.  This is something that will have to be done\nby the stubs, because I don\u0027t know which invokes are native.  Oh, and\nthere will also need to be an artUpdateDebugger call on the exception\npath.\n\nI\u0027m passing the DalvikPC to the stub, and am using special\ncodes (-1 and -2) to denote method entry and exit.  The stub\nrecovers the current Method* and Thread* and passes them on to\nartUpdateDebugger().\n\nWhen we\u0027re compiling in this special mode, all optimizations which\nmight result in code motion or suppressed load/store of a Dalvik\nregister are turned off.  No register promotion is done, so everything\nwill be in its home location.\n\nChange-Id: Iaf66f4d0d094a1699269d0a1ad1ed33e7613aef8\n"
