* Interpreter-only mode should cause dex-to-dex compilation.Ian Rogers2014-04-171-0/+4
| | | | | | | | | | | Also, fix quick iget/iput that had similar issues to: https://android-review.googlesource.com/91423 Also, remove fall-back resolution code from quick invokes/igets/iputs as we allow class loading for the exception throw and regular verification already allows class loading.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Updates Thread::CreateInternalStackTrace to support both transactional and non-transactional modes using template. Generalizes non-transactional mode for invariant fields (which are set only once). Removes ArrayLog::VisitRoots as we never create Array logs of ObjectArray. As ObjectArray elements are set using Object::SetFieldObject, they are already recorded in the object logs: the object is the array itself and the offset corresponds to the element index in this array. And also checks we never log ObjectArray in array logs. Fixes location of thrown exception when calling native method during class initialization. Change-Id: Idbc368d3b8292b85ff40bc8a7c559e085477bf89

* Implicit null/suspend checks (oat version bump)Dave Allison2014-03-131-1/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds the ability to use SEGV signals to throw NullPointerException exceptions from Java code rather than having the compiler generate explicit comparisons and branches. It does this by using sigaction to trap SIGSEGV and when triggered makes sure it's in compiled code and if so, sets the return address to the entry point to throw the exception. It also uses this signal mechanism to determine whether to check for thread suspension. Instead of the compiler generating calls to a function to check for threads being suspended, the compiler will now load indirect via an address in the TLS area. To trigger a suspend, the contents of this address are changed from something valid to 0. A SIGSEGV will occur and the handler will check for a valid instruction pattern before invoking the thread suspension check code. If a user program taps SIGSEGV it will prevent our signal handler working. This will cause a failure in the runtime. There are two signal handlers at present. You can control them individually using the flags -implicit-checks: on the runtime command line. This takes a string parameter, a comma separated set of strings. Each can be one of: none switch off null null pointer checks suspend suspend checks all all checks So to switch only suspend checks on, pass: -implicit-checks:suspend There is also -explicit-checks to provide the reverse once we change the default. For dalvikvm, pass --runtime-arg -implicit-checks:foo,bar The default is -implicit-checks:none There is also a property 'dalvik.vm.implicit_checks' whose value is the same string as the command option. The default is 'none'. For example to switch on null checks using the option: setprop dalvik.vm.implicit_checks null It only works for ARM right now. Bumps OAT version number due to change to Thread offsets. Bug: 13121132 Change-Id: If743849138162f3c7c44a523247e413785677370
* Make use of profiling information for dex2oatDave Allison2014-03-071-4/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the profile file exists, the compiler driver will read it and store the data in an internal map. Then, when we want to work out whether to compile a method or not, the map is consulted and if the method shows up with a high enough percentage of use we compile it. The profile file itself is created by installd and is writeable by the app. The file is in /data/dalvik-cache/profiles and is named by the package name. This also modifies the profiler itself to: 1. Only count runnable threads (not suspended threads) in the profile 2. Use system properties to allow tuning of the profile parameters 3. Merge profiles from multiple processes using file locking.

* Avoid marking old class linker and intern table roots during pause.Mathieu Chartier2014-03-041-15/+20
| | | | | | | | | | | | | | | | | | | | The new root visiting logic has a concept of a root log which holds new roots which were added since the start of the GC. This is an optimization since it lets us only mark these newly added roots during the pause (or pre-cleaning) since the other roots intern table and class linker roots were marked concurrently at the start of the GC. Before (EvaluateAndApplyChanges): MarkConcurrentRoots: Sum: 605.193ms After: MarkConcurrentRoots: Sum: 271.858ms This should also reduce pathological GC pauses which used to be able to happen when the intern table or class linker became "dirty" during the concurrent GC.

* Add custom SIGSEGV handler to help find heap corruption.Mathieu Chartier2014-02-281-0/+7
| | | | | | | | | | | | | | | | The new signal handler prints heap diagnostics when you get a SIGSEGV. Added a fault message member in runtime which is modifiable by Runtime::SetFaultMessage. When you get a SIGSEGV it will print out whatever is stored in this string as well as the normal information. This is useful for debugging heap corruption since it lets you see which threads were in which methods when the last GC occured. Added some smarter object dumping logic when the faulting address is in the heap. Bug: 12934910 Change-Id: Ia72be2c39f70ad711cbd746d66fad2b617d5d29f

* Remove blacklistSebastien Hertz2014-02-171-3/+80
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Removes the class initialization blacklist and use transaction to detect and revert class initialization attempting to invoke native method. This only concerns class initialization happening at compilation time when generating an image (like boot.art for the system). In transactional mode, we log every object's field assignment and array update. Therefore we're able to abort a transaction to restore values of fields and array as they were before the transaction starts. We also log changes to the intern string table so we can restore its state prior to transaction start. Since transactional mode only happens at compilation time, we don't need to log all these changes at runtime. In order to reduce the overhead of testing if transactional mode is on/off, we templatize interfaces of mirror::Object and mirror::Array, respectively responsible for setting a field and setting an array element. For various reasons, we skip some specific fields from transaction: - Object's class and array's length must remain unchanged so garbage collector can compute object's size. - Immutable fields only set during class loading: list of fields, method, dex caches, vtables, ... as all classes have been loaded and verified before a transaction occurs. - Object's monitor for performance reason. Before generating the image, we browse the heap to collect objects that need to be written into it. Since the heap may still holds references to unreachable objects due to aborted transactions, we trigger one collection at the end of the class preinitialization phase. Since the transaction is held by the runtime and all compilation threads share the same runtime, we need to ensure only one compilation thread has exclusive access to the runtime. To workaround this issue, we force class initialization phase to run with only one thread. Note this is only done when generating image so application compilation is not impacted. This issue will be addressed in a separate CL. Bug: 9676614 Change-Id: I221910a9183a5ba6c2b99a277f5a5a68bc69b5f9
