This only\nconcerns class initialization happening at compilation time when generating an\nimage (like boot.art for the system).\n\nIn transactional mode, we log every object\u0027s field assignment and array update.\nTherefore we\u0027re able to abort a transaction to restore values of fields and\narray as they were before the transaction starts. We also log changes to the\nintern string table so we can restore its state prior to transaction start.\n\nSince transactional mode only happens at compilation time, we don\u0027t need to log\nall these changes at runtime. In order to reduce the overhead of testing if\ntransactional mode is on/off, we templatize interfaces of mirror::Object and\nmirror::Array, respectively responsible for setting a field and setting an\narray element.\n\nFor various reasons, we skip some specific fields from transaction:\n- Object\u0027s class and array\u0027s length must remain unchanged so garbage collector\ncan compute object\u0027s size.\n- Immutable fields only set during class loading: list of fields, method,\ndex caches, vtables, ... as all classes have been loaded and verified before a\ntransaction occurs.\n- Object\u0027s monitor for performance reason.\n\nBefore generating the image, we browse the heap to collect objects that need to\nbe written into it. Since the heap may still holds references to unreachable\nobjects due to aborted transactions, we trigger one collection at the end of\nthe class preinitialization phase.\n\nSince the transaction is held by the runtime and all compilation threads share\nthe same runtime, we need to ensure only one compilation thread has exclusive\naccess to the runtime. To workaround this issue, we force class initialization\nphase to run with only one thread. Note this is only done when generating image\nso application compilation is not impacted. This issue will be addressed in a\nseparate CL.\n\nBug: 9676614\nChange-Id: I221910a9183a5ba6c2b99a277f5a5a68bc69b5f9\n"

If this thread is the thread we\u0027re waiting\nto run the check point then the VM will deadlock.\nThis deadlock occurred unnoticed as the call to check for wait safety was\nremoved in: https://googleplex-android-review.googlesource.com/#/c/249423/1.\n\nNewTimingLogger:\nExisting timing log states when a split ends but not when it begins. This isn\u0027t\ngood for systrace, in the context of GC it means that races between mutators\nand the GC are hard to discover what phase the GC is in, we know what phase it\njust finished and derive but that\u0027s not ideal.\n\nSupport for only 1 discontinuous space:\nCode special cases continuous and large object space, rather than assuming we\ncan have a collection of both.\n\nSorted atomic stacks:\nUsed to improve verification performance.
