TODO: Test and fix bugs in mips64. Saves 16 bytes per most ArtMethod, 7.5MB reduction in system PSS. Some of the savings are from removal of virtual methods and direct methods object arrays. Bug: 19264997 (cherry picked from commit e401d146407d61eeb99f8d6176b2ac13c4df1e33) Change-Id: I622469a0cfa0e7082a2119f3d6a9491eb61e3f3d Fix some ArtMethod related bugs Added root visiting for runtime methods, not currently required since the GcRoots in these methods are null. Added missing GetInterfaceMethodIfProxy in GetMethodLine, fixes --trace run-tests 005, 044. Fixed optimizing compiler bug where we used a normal stack location instead of double on ARM64, this fixes the debuggable tests. TODO: Fix JDWP tests. Bug: 19264997 Change-Id: I7c55f69c61d1b45351fd0dc7185ffe5efad82bd3 ART: Fix casts for 64-bit pointers on 32-bit compiler. Bug: 19264997 Change-Id: Ief45cdd4bae5a43fc8bfdfa7cf744e2c57529457 Fix JDWP tests after ArtMethod change Fixes Throwable::GetStackDepth for exception event detection after internal stack trace representation change. Adds missing ArtMethod::GetInterfaceMethodIfProxy call in case of proxy method. Bug: 19264997 Change-Id: I363e293796848c3ec491c963813f62d868da44d2 Fix accidental IMT and root marking regression Was always using the conflict trampoline. Also included fix for regression in GC time caused by extra roots. Most of the regression was IMT. Fixed bug in DumpGcPerformanceInfo where we would get SIGABRT due to detached thread. EvaluateAndApplyChanges: From ~2500 -> ~1980 GC time: 8.2s -> 7.2s due to 1s less of MarkConcurrentRoots Bug: 19264997 Change-Id: I4333e80a8268c2ed1284f87f25b9f113d4f2c7e0 Fix bogus image test assert Previously we were comparing the size of the non moving space to size of the image file. Now we properly compare the size of the image space against the size of the image file. Bug: 19264997 Change-Id: I7359f1f73ae3df60c5147245935a24431c04808a [MIPS64] Fix art_quick_invoke_stub argument offsets. ArtMethod reference's size got bigger, so we need to move other args and leave enough space for ArtMethod* and 'this' pointer. This fixes mips64 boot.

* ART: Clean up arm64 kNumberOfXRegisters usage.Vladimir Marko2015-05-261-0/+2
| | | | | | | | | | | | | | | | | | | | | Avoid undefined behavior for arm64 stemming from 1u << 32 in loops with upper bound kNumberOfXRegisters. Create iterators for enumerating bits in an integer either from high to low or from low to high and use them for <arch>Context::FillCalleeSaves() on all architectures. Refactor runtime/utils.{h,cc} by moving all bit-fiddling functions to runtime/base/bit_utils.{h,cc} (together with the new bit iterators) and all time-related functions to runtime/base/time_utils.{h,cc}. Improve test coverage and fix some corner cases for the bit-fiddling functions. Bug: 13925192 (cherry picked from commit 80afd02024d20e60b197d3adfbb43cc303cf29e0) Change-Id: I905257a21de90b5860ebe1e39563758f721eab82
* Add a flag to StackVisitor for inlining.Nicolas Geoffray2015-05-111-2/+3
| | | | | | | | | The flag tells whether the stack walk needs to include inlined Java frames. This does not do anything just yet, as we're not inlining anyways. Change-Id: I716e25094fe56fa335ca1f9a398c1bcdba478e73
* Support multiple instrumentation clientsSebastien Hertz2015-05-071-4/+7
| | | | | | | | | | | Changes Instrumentation::ConfigureStubs to support multiple clients that need different levels of instrumenation. A client is identified by a string key used to save the desired instrumentation level. Also adds regression gtest instrumentation_test and some cleanup.

* ART: Fix Trace types, check minimum buf sizeAndreas Gampe2015-04-251-11/+25
| | | | | | | | | Also make streaming mode adhere to the given buffer (and fix the case where the buffer is too small for a packet). This is important to not lose too much tracing information when the runtime is destroyed with an unflushed buffer. Change-Id: I6525fe4326ac5c3d7c9cda41c54a2a911ca889b7
* ART: Streaming trace modeAndreas Gampe2015-04-151-63/+347
| | | | | | | | | | | | | | | | | | | | | | | | | | | Add a streaming mode for tracing. Streaming uses a buffer of 16KB and writes to the output when that buffer gets full. Streaming mode can be enabled with -Xmethod-trace-stream and is currently not exposed otherwise. Add a python script that can parse the streaming format, which simply contains strings for newly encountered threads and methods inline, and create output that can be used with traceview. Add Trace::Pause and Trace::Abort, which can pause and abort tracing. Abort is different from Stop in that it does not write the data. Add code to the zygote hooks JNI implementation that pauses tracing before the fork, making sure that a child cannot clobber the parent's data. Add code to the zygote hooks JNI implementation that aborts old tracing and starts new tracing in the child after the fork. Currently base the output on the pid. This will not work on an unmodified device, as the profiles directory is not generally writable, but we do not have enough information at that point. Consider a scheme that restarts tracing later.

* Fix sampling profiler race conditionMathieu Chartier2015-03-111-16/+17
| | | | | | | | | | | | | | | | Thread 1 is running RunSamplingThread and has just read trace into the_trace. Thread 2 is calling Trace::Stop and has just suspended all the threads. At this point thread 1 is blocked on the SuspendAll. Thread 2 goes and deletes the trace which Thread 1 still has a pointer to, calls ResumeAll(). At this point thread 1 suspends the threads and adds samples to the just deleted trace. The fix is to join the thread before we delete the trace.

* Add JITMathieu Chartier2015-02-231-1/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently disabled by default unless -Xjit is passed in. The proposed JIT is a method JIT which works by utilizing interpreter instrumentation to request compilation of hot methods async during runtime. JIT options: -Xjit / -Xnojit -Xjitcodecachesize:N -Xjitthreshold:integervalue The JIT has a shared copy of a compiler driver which is accessed by worker threads to compile individual methods. Added JIT code cache and data cache, currently sized at 2 MB capacity by default. Most apps will only fill a small fraction of this cache however. Added support to the compiler for compiling interpreter quickened byte codes. Added test target ART_TEST_JIT=TRUE and --jit for run-test. TODO: Clean up code cache. Delete compiled methods after they are added to code cache. Add more optimizations related to runtime checks e.g. direct pointers for invokes. Add method recompilation. Move instrumentation to DexFile to improve performance and reduce memory usage. Bug: 17950037 Change-Id: Ifa5b2684a2d5059ec5a5210733900aafa3c51bca

| | | | | | | | | | | | | Refactor the RuntimeOptions to be a type-safe map (VariantMap, see runtime_options.h) and the ParsedOptions to delegate the parsing to CmdlineParser (see cmdline/cmdline_parser.h). This is the start of a command line parsing refactor, and may include more in the future (dex2oat, patchoat, etc).

| | | | | | | | | | | Fix associated errors about unused paramenters and implict sign conversions. For sign conversion this was largely in the area of enums, so add ostream operators for the effected enums and fix tools/generate-operator-out.py. Tidy arena allocation code and arena allocated data types, rather than fixing new and delete operators. Remove dead code. Change-Id: I5b433e722d2f75baacfacae4d32aef4a828bfe1b
* C++11 related clean-up of DISALLOW_..Ian Rogers2014-10-221-0/+3
| | | | | | | | | | | | | | | | | | Move DISALLOW_COPY_AND_ASSIGN to delete functions. By no having declarations with no definitions this prompts better warning messages so deal with these by correcting the code. Add a DISALLOW_ALLOCATION and use for ValueObject and mirror::Object. Make X86 assembly operand types ValueObjects to fix compilation errors. Tidy the use of iostream and ostream. Avoid making cutils a dependency via mutex-inl.h for tests that link against libart. Push tracing dependencies into appropriate files and mutex.cc. x86 32-bit host symbols size is increased for libarttest, avoid copying this in run-test 115 by using symlinks and remove this test's higher than normal ulimit. Fix the RunningOnValgrind test in RosAllocSpace to not use GetHeap as it returns NULL when the heap is under construction by Runtime. Change-Id: Ia246f7ac0c11f73072b30d70566a196e9b78472b

* Object model changes to support 64bit.Ian Rogers2014-02-061-10/+10
| | | | | | | | | | | | | | | | | | | | | | | Modify mirror objects so that references between them use an ObjectReference value type rather than an Object* so that functionality to compress larger references can be captured in the ObjectRefererence implementation. ObjectReferences are 32bit and all other aspects of object layout remain as they are currently. Expand fields in objects holding pointers so they can hold 64bit pointers. Its expected the size of these will come down by improving where we hold compiler meta-data. Stub out x86_64 architecture specific runtime implementation. Modify OutputStream so that reads and writes are of unsigned quantities. Make the use of portable or quick code more explicit. Templatize AtomicInteger to support more than just int32_t as a type. Add missing, and fix issues relating to, missing annotalysis information on the mutator lock. Refactor and share implementations for array copy between System and uses elsewhere in the runtime. Fix numerous 64bit build issues. Change-Id: I1a5694c251a42c9eff71084dfdd4b51fff716822

* | Selective deoptimization.Sebastien Hertz2014-01-131-0/+2
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Update the instrumentation to allow selective deoptimization. Separate instrumentation listener registration from stubs configuration. A listener is now responsible for configuring the appropriate stubs. - The method tracing listener installs instrumentation entry/exit stubs or the interpreter depending on the accuracy of events we want (controlled by kDeoptimizeForAccurateMethodEntryExitListeners). - The debugger registers itself as an instrumentation listener but does not modify methods entrypoints. It only does this on demand when deoptimizing one method or all the methods. The selective deoptimization is used for breakpoint only. When a breakpoint is requested, the debugger deoptimizes this method by setting its entrypoint to the interpreter stub. As several breakpoints can be set on the same method, we deoptimize only once. When the last breakpoint on a method is removed, we reoptimize it by restoring the original entrypoints. The full deoptimization is used for method entry, method exit and single-step events. When one of these events is requested, we force eveything to run with the interpreter (except native and proxy methods). When the last of these events is removed, we restore all methods entrypoints except those which are currently deoptimized. Deoptimizing a method requires all mutator threads be suspended in order to walk each thread's stack and ensure no code is actually executing while we modify methods entrypoints. Suspending all the threads requires to not hold any lock. In the debugger, we deoptimize/undeoptimize when the JDWP event list changes (add or remove a breakpoint for instance). During the update, we need to hold the JDWP event list lock. This means we cannot suspend all the threads at this time. In order to deal with these constraints, we support a queue of deoptimization requests. When an event needs selective/full deoptimization/undeoptimization, we save its request in the queue. Once we release the JDWP event list lock, we suspend all the threads, process this queue and finally resume all the threads. This is done in Dbg::ManageDeoptimization. Note: threads already suspended before doing this remain suspended so we don't "break" debugger suspensions. When we deoptimize one method or every method, we need to browse each thread's stack to install instrumentation exit PC as return PC and save information in the instrumentation stack frame. Now we can deoptimize multiple times during the execution of an application, we need to preserve exisiting instrumentation frames (which is the result of a previous deoptimization). This require to push new instrumentation frames before existing ones so we don't corrupt the instrumentation stack frame while walking the stack.

* Propagate 'this_object' for method unwind event.Sebastien Hertz2013-11-191-1/+2
| | | | | | Propagates the 'this_object' to InstrumentationListener::MethodUnwind callback. Change-Id: I12561f1a611b8399b94e669f9b8a6eaaf1a58631
* Introduce Signature type to avoid string comparisons.Ian Rogers2013-09-261-1/+1
| | | | | | | | | | | | | | | Method resolution currently creates strings to then compare with strings formed from methods in other dex files. The temporary strings are purely created for the sake of comparisons. This change creates a new Signature type that represents a method signature but not as a string. This type supports comparisons and so can be used when searching for methods in resolution. With this change malloc is no longer the hottest method during dex2oat (now its memset) and allocations during verification have been reduced. The verifier is commonly what is populating the dex cache for methods and fields not declared in the dex file itself. Change-Id: I5ef0542823fbcae868aaa4a2457e8da7df0e9dae
