This allows\none to force java frames to exit early. Exited frames have all of\ntheir normal locks released.\n\nWe implement this by modifying the existing method exit events to\nallow one to modify the exit value during the callback. This is used\nto implement ForceEarlyReturn by adding internal-only events that will\nchange the return value of methods once they return (using\nkForcePopFrame) avoiding the need to modify the actual interpreter\nvery deeply. This also makes it simple to continue to use the standard\ndeoptimization functions to force the actual return.\n\nIn order to simplify book-keeping the internal event is refcounted,\nnot associated with any specific jvmtiEnv, and only settable on\nspecific threads. The internal event is added by the ForceEarlyReturn\nfunction and then removed by the MethodExit event when we update the\nreturn value.\n\nBug: 130028055\nTest: ./test.py --host\nChange-Id: Ifa44605b4e8032605f503a654ddf4bd2fc6b60bf\n" }, { "commit": "0aa7a5a6a7bc350b79351f52e26c97747e927acf", "tree": "a583889668d9703d16d37586d56421bd27c62661", "parents": [ "e12575640dca5118bf96245f373acda276c22178" ], "author": { "name": "Alex Light", "email": "allight@google.com", "time": "Wed Oct 10 15:58:14 2018 +0000" }, "committer": { "name": "Alex Light", "email": "allight@google.com", "time": "Thu Oct 11 16:41:54 2018 -0700" }, "message": "Revert^4 \"JVMTI PopFrame support\"\n\nThis reverts commit 202b617acf477e8e8e11915f467120a0bd518e74.\nThis unreverts commit 202b617acf.\nThis unreverts commit 88a2a9d7a1.\n\nThere were several bugs with the implementation of pop-frame related\nto interactions between the jit, exception handling, class-loading,\nand deoptimization.\n\n- We were instrumenting the target thread stack in cases where it was\n unnecessary which caused the exception handler to incorrectly\n determine that a method was not deoptimizable. This caused the\n pop-frame to be ignored.\n\n- We were incorrectly sending ExceptionCatch events if an exception\n suppressed by pop-frame would have been caught in the current frame.\n\n- We were allowing pop-frame to be used on threads suspended in the\n ClassLoad or ClassPrepare events despite having surprising semantics\n in that situation (see b/117615146).\n\nNeeded to modify test 1953 slightly for inclusion in CTS. I needed to\nmake the CTS entrypoint not run the class-load tests (since the cts\nconfiguration means the classes are loaded by the verifier and not the\ninterpreter). I updated the expected.txt and check script to reflect\nthis.\n\nReason for revert: Fixed issue causing Exception events to sometimes\n eat PopFrame and other issues.\n\nTest: ./test.py --host\nTest: ./art/tools/run-libjdwp-tests.sh --mode\u003dhost\n\nBug: 73255278\nBug: 111357976\nBug: 117533193\nBug: 117615146\n\nChange-Id: I655c4fe769938cf41d7589f931d6710cf2001506\n" }, { "commit": "202b617acf477e8e8e11915f467120a0bd518e74", "tree": "4d1124b540984f970acaf494f4fd85cc347fbd57", "parents": [ "1c7b1fcf0ff29d83d13d38d0451a54474ccf5964" ], "author": { "name": "Nicolas Geoffray", "email": "ngeoffray@google.com", "time": "Wed Oct 10 07:47:58 2018 +0000" }, "committer": { "name": "Nicolas Geoffray", "email": "ngeoffray@google.com", "time": "Wed Oct 10 07:47:58 2018 +0000" }, "message": "Revert \"Revert^2 \"JVMTI PopFrame support\"\"\n\nThis reverts commit 1c7b1fcf0ff29d83d13d38d0451a54474ccf5964.\n\nBug: 73255278\nBug: 111357976\nbug: 117533193\n\nReason for revert: Test failures\n\nChange-Id: I9da863fd95264007c4efeb85539e704e83499dcf\n" }, { "commit": "1c7b1fcf0ff29d83d13d38d0451a54474ccf5964", "tree": "b978817acd252f10bd4648d3582ac9459fc9a0f4", "parents": [ "59b950f53152c169464ba8c63d44102eeba1e594" ], "author": { "name": "Alex Light", "email": "allight@google.com", "time": "Fri Oct 05 23:42:12 2018 +0000" }, "committer": { "name": "Alex Light", "email": "allight@google.com", "time": "Mon Oct 08 13:18:35 2018 -0700" }, "message": "Revert^2 \"JVMTI PopFrame support\"\n\nThis reverts commit f67d0cbf2743b29aa6e1be7ae2f71762b8762785.\n\nRedefine-stress causes classes to be loaded at slightly different\nplaces due to the deep verification needed to redefine a class.
