      "message": "Implicit null/suspend checks (oat version bump)\n\nThis adds the ability to use SEGV signals\nto throw NullPointerException exceptions from Java code rather\nthan having the compiler generate explicit comparisons and\nbranches.  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"
