Brings back resolved methods table\nshort-cut and associated fast paths to use this (such as in Proxy). Adds\na resolution method that is used as the trampoline for static and direct\nmethods.\n\nAdd source file and line number to Throwable::Dump.\n\nMethodHelper knowledge of runtime methods.\n\nChange-Id: Ieae1b74c24072e6327a5bb2cad466f04e3c46c4d\n" }, { "commit": "a004aa933a58428489e42d77f707c2b063b73747", "tree": "1224764c4a524957e94dfe2d27e277d024986668", "parents": [ "573b7c9324b11ff7f42f68c9ad52d26ebc4b6d12" ], "author": { "name": "Brian Carlstrom", "email": "bdc@google.com", "time": "Wed Feb 08 18:05:09 2012 -0800" }, "committer": { "name": "Brian Carlstrom", "email": "bdc@google.com", "time": "Thu Feb 16 17:48:28 2012 -0800" }, "message": "user build support for art (2 of 3)\n\nChange-Id: I4696fee58e43db48540e2442c4235fc4bb02d9e3\n" }, { "commit": "f1a5adc87760f938b01df26d906295063546b259", "tree": "99f9a917b667cdaab69fa7df0978e4310eb6c207", "parents": [ "5b1f162d9cbec1c6b2863bd220bdaecdcb18b139" ], "author": { "name": "Elliott Hughes", "email": "enh@google.com", "time": "Fri Feb 10 18:09:35 2012 -0800" }, "committer": { "name": "Elliott Hughes", "email": "enh@google.com", "time": "Fri Feb 10 18:09:35 2012 -0800" }, "message": "Reduce StringPiece usage a bit.\n\nVarious easy cases, in case we want to move towards making the StringPiece\nconstructors explicit.\n\nChange-Id: I49e5efc5b787f847ab4cb12d66d1d16aed03fa67\n" }, { "commit": "223f20fa939c386c695977263780dea2195093db", "tree": "642d1abe5dfbf2239bf239e8e91bebd333384378", "parents": [ "a56fcd60596ae8694da21fccde5c56832e437c56" ], "author": { "name": "Brian Carlstrom", "email": "bdc@google.com", "time": "Sat Feb 04 23:06:55 2012 -0800" }, "committer": { "name": "Brian Carlstrom", "email": "bdc@google.com", "time": "Sat Feb 04 23:24:56 2012 -0800" }, "message": "Remove old code to support multiple images\n\nChange-Id: I29bc2f216361ac4ed0cc0fefb7e3c46ee64e0ae8\n" }, { "commit": "d9c67be7c116875d96b31e640ad47d587b205605", "tree": "55ba94dde3916dfb88681e4967e4a45926436716", "parents": [ "763d5fb2f83d9c93b5b764533005865a3d1034e1" ], "author": { "name": "Elliott Hughes", "email": "enh@google.com", "time": "Thu Feb 02 19:54:06 2012 -0800" }, "committer": { "name": "Elliott Hughes", "email": "enh@google.com", "time": "Fri Feb 03 09:28:44 2012 -0800" }, "message": "Start parallelizing dex2oat.\n\nThis is enough to perform type resolution and verification in parallel.\n\nThere appears to be a bug in InitCpu --- if you start enough threads\nat once, the CHECK at the end starts to fail, with self_check \u003d\u003d NULL; I\u0027ve\ncommented it out for now, but this will cause test failures until it\u0027s fixed.\n\nChange-Id: I4919682520bc01d3262c6b3d00c7bd2c2860a52e\n" }, { "commit": "2faa5f1271587cda765f26bcf2951065300a01ff", "tree": "c59557857c36741cfcd1b6bf5ae039886a8ad6e7", "parents": [ "0850c69c88d49efd4075288511b70d6c032bd0c8" ], "author": { "name": "Elliott Hughes", "email": "enh@google.com", "time": "Mon Jan 30 14:42:07 2012 -0800" }, "committer": { "name": "Elliott Hughes", "email": "enh@google.com", "time": "Mon Jan 30 16:46:29 2012 -0800" }, "message": "Fix copyright headers.\n\nChange-Id: I5b7bc76a370238d810d78522bd5531600746700f\n" }, { "commit": "131aef8c94292cc530da2fd91ee98d1432352959", "tree": "58bc993648e93dc6e84d701457f0cda0b0ec82cb", "parents": [ "6622e5dcf77fd1af7bdec45466da590471b53ba0" ], "author": { "name": "Elliott Hughes", "email": "enh@google.com", "time": "Fri Jan 27 11:53:35 2012 -0800" }, "committer": { "name": "Elliott Hughes", "email": "enh@google.com", "time": "Fri Jan 27 11:53:35 2012 -0800" }, "message": "Only allow one thread to abort at a time.\n\nFound when looking to see if Google Earth had fixed their JNI bug yet.\n\nChange-Id: I8768248625869d344ba04ecf4fec06047f76c3ce\n" }, { "commit": "ff17f1fd3ff32f93e45588eb2b158832d73f9afa", "tree": "deab04f6a2ad7f1dbaf0e6be266512d663e3dd91", "parents": [ "a7679b67ca945194fa2442015e606cd250f0de2b" ], "author": { "name": "Elliott Hughes", "email": "enh@google.com", "time": "Tue Jan 24 18:12:29 2012 -0800" }, "committer": { "name": "Elliott Hughes", "email": "enh@google.com", "time": "Tue Jan 24 18:12:29 2012 -0800" }, "message": "Remove various bits of lint.\n\nChange-Id: I5f8f61766d2add7fd7ff40d463ea03cb20515988\n" }, { "commit": "6b3557571e798b60df995f978fa01c0ca1980dfd", "tree": "ce56e52d67d20bf3204074b48d2be1d15644ef54", "parents": [ "f4222065170130a31513dc63e2c2808db80860f1" ], "author": { "name": "Elliott Hughes", "email": "enh@google.com", "time": "Fri Jan 13 16:49:08 2012 -0800" }, "committer": { "name": "Elliott Hughes", "email": "enh@google.com", "time": "Fri Jan 13 16:49:08 2012 -0800" }, "message": "Make pthread_mutex_t destruction safer during shutdown.\n\nIf we have suspended daemon threads, they might be holding some of the mutexes\nwe need to destroy, so we can\u0027t assert that we successfully destroyed them.
