Any\nnative PC located within compiled Dex code that is found in a\nstack walk should have an exact match in the table.\n\nIn future CLs we\u0027ll add data compression (probably uLeb128) and\nmay add inflation on first use to a faster access map (instead of\nthe current linear search).\n\nNote that this CL introduces somewhat of a regression in the\ncapabilities of oat-dump. Because the mapping table no longer\nassociates each native intruction with its Dex counter-part, the\nnative code disassembly no longer includes interspersed Dex\ndisassembly.\n\nNote also that as of this CL, the compiler is adopting the 100-char\nline length limit used in the rest of Art. The 80-char limit\nshould still be used in any code that we expect to upstream to\nllvm.\n\nChange-Id: I1beca4d57c41e8161bf746bc62abbce08d5bcb4d\n" }, { "commit": "b726dcb581bf72da46527378ccb6889020f0e6e9", "tree": "c0383ed788652926e93147e50d659ed226519548", "parents": [ "fd678beb171a4686a4f2d53ca4188a4ade8fa54e" ], "author": { "name": "Ian Rogers", "email": "irogers@google.com", "time": "Wed Sep 05 08:57:23 2012 -0700" }, "committer": { "name": "Ian Rogers", "email": "irogers@google.com", "time": "Wed Sep 05 09:06:19 2012 -0700" }, "message": "Rename GlobalSynchronization to Locks\n\nAlso address some review comments in common_throws relating to\nToStr\u003cInvokeType\u003e and exception detail messages.\n\nChange-Id: Ibf2c0f147689fa236d349bd7f01eed3c2522552b\n" }, { "commit": "c747cffa950b8398cb8844d47e2253214c855750", "tree": "4b77ecc1dc6f2a76c755381a2925f34ed080c74f", "parents": [ "faf459e5decdfcf6dd7844947898beefe31e6435" ], "author": { "name": "Ian Rogers", "email": "irogers@google.com", "time": "Fri Aug 31 18:20:08 2012 -0700" }, "committer": { "name": "Ian Rogers", "email": "irogers@google.com", "time": "Fri Aug 31 18:26:30 2012 -0700" }, "message": "Runnable -\u003e Suspended -\u003e Runnable, avoid 2 locks\n\nAllow some freedom in the Transtion code to change thread state without\nholding a lock in 2 cases where it is safe.\n\n1) into Suspended we know that we\u0027re suspended and so checking the\nsuspend count is a mute point.\n2) when going into Runnable we can do a racy check before doing a\nsecondary check after we\u0027ve acquired a share on the mutator lock.\n\nChange-Id: Ibf0e5f42acc1ff3cf06312ef001a74344d4dfa8c\n" }, { "commit": "9a4f003f9a6da8e4c6ee279bd2a13aac37648183", "tree": "ce78afe7c842c8ff99d52c0a09bfe758d67d037f", "parents": [ "cfb21d92796087963c092b69110a2e7ff7a03a55" ], "author": { "name": "jeffhao", "email": "jeffhao@google.com", "time": "Thu Aug 30 16:17:40 2012 -0700" }, "committer": { "name": "jeffhao", "email": "jeffhao@google.com", "time": "Fri Aug 31 10:49:06 2012 -0700" }, "message": "Remove the THROW_VERIFICATION_ERROR op and supporting code.\n\nChange-Id: Idc40a2c379048c7e3d74f50b2bd765a507a417ce\n" }, { "commit": "9efc3e03982f042c3ce67cc2c64dbe0f0986119b", "tree": "3b2ba9bc2b64f1ef3bccc10fb62aec37fcac3d43", "parents": [ "cd30d82113913125222454d41981c8740724fb30" ], "author": { "name": "Brian Carlstrom", "email": "bdc@google.com", "time": "Fri Aug 17 17:47:17 2012 -0700" }, "committer": { "name": "Brian Carlstrom", "email": "bdc@google.com", "time": "Fri Aug 17 17:47:17 2012 -0700" }, "message": "Fix x86 build where compiler found lock issue\n\nChange-Id: I00eba554539cf9f700c38ccf42eeafd011725a9f\n" }, { "commit": "00f7d0eaa6bd93d33bf0c1429bf4ba0b3f28abac", "tree": "6a2172ece15c4699e6c2a67ce76f019db0a9a21d", "parents": [ "634ea28f78c4a138e6a1de54eae8696095422415" ], "author": { "name": "Ian Rogers", "email": "irogers@google.com", "time": "Thu Jul 19 15:28:27 2012 -0700" }, "committer": { "name": "Ian Rogers", "email": "irogers@google.com", "time": "Tue Aug 14 10:45:52 2012 -0700" }, "message": "Global lock levels.\n\nIntroduce the notion of the mutators/GC being a shared-exclusive (aka\nreader-writer) lock.

"Improve our check for whether a thread is still starting up.\n\nIt turns out that there was a race in Thread::Create that could confuse our\nsuspend-count sanity checking. Tested by manually inserting a sleep(3) there.\nI could have added an extra field to Thread, but since we only need to check\nthis once if we do a GC while a thread is still starting up, a simple string\ncomparison will be fine.\n\n thread_list.cc:79] Thread[10,tid\u003d7447,VmWait,Thread*\u003d0x00d23060,peer\u003d0x60f1b350,\"\u003cnative thread without managed peer\u003e\"] suspend count
