Improve handling of daemon threads after runtime shutdown The main issue comes from the fact that user daemon threads are allowed to continue running after the runtime has shutdown. They may still have a JNI env pointer. To prevent crashing if they call into the env, we replace the function pointers with functions that sleep forever. The other issue is that user daemon threads that are blocked in an ART condition variable may get woken up by another user daemon inside of Monitor::Notify or by a spurious wakeup (i.e. SIGQUIT). To deal with this issue, we check the JNI env for shutdown runtime when we are woken up from a condition variable wait. This check fixes test 132 with --host --gdb --interpreter. Previously this test crashed since dlclose was somehow causing a spurious futex wakeup. TODO: Investigate adding a unit test. Bug: 18577101 Change-Id: I479b38968ee9fbc4ee4b252ee2528787279972cc

ART: Streaming trace mode 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.

Unify ART's various implementations of bit_cast. ART had several implementations of art::bit_cast: 1. one in runtime/base/casts.h, declared as: template <class Dest, class Source> inline Dest bit_cast(const Source& source); 2. another one in runtime/utils.h, declared as: template<typename U, typename V> static inline V bit_cast(U in); 3. and a third local version, in runtime/memory_region.h, similar to the previous one: template<typename Source, typename Destination> static Destination MemoryRegion::local_bit_cast(Source in); This CL removes versions 2. and 3. and changes their callers to use 1. instead. That version was chosen over the others as: - it was the oldest one in the code base; and - its syntax was closer to the standard C++ cast operators, as it supports the following use: bit_cast<Destination>(source) since `Source' can be deduced from `source'.

Compress the Dex register maps built by the optimizing compiler. - Replace the current list-based (fixed-size) Dex register encoding in stack maps emitted by the optimizing compiler with another list-based variable-size Dex register encoding compressing short locations on 1 byte (3 bits for the location kind, 5 bits for the value); other (large) values remain encoded on 5 bytes. - In addition, use slot offsets instead of byte offsets to encode the location of Dex registers placed in stack slots at small offsets, as it enables more values to use the short (1-byte wide) encoding instead of the large (5-byte wide) one. - Rename art::DexRegisterMap::LocationKind as art::DexRegisterLocation::Kind, turn it into a strongly-typed enum based on a uint8_t, and extend it to support new kinds (kInStackLargeOffset and kConstantLargeValue). - Move art::DexRegisterEntry from compiler/optimizing/stack_map_stream.h to runtime/stack_map.h and rename it as art::DexRegisterLocation. - Adjust art::StackMapStream, art::CodeGenerator::RecordPcInfo, art::CheckReferenceMapVisitor::CheckOptimizedMethod, art::StackVisitor::GetVRegFromOptimizedCode, and art::StackVisitor::SetVRegFromOptimizedCode. - Implement unaligned memory accesses in art::MemoryRegion. - Use them to manipulate data in Dex register maps. - Adjust oatdump to support the new Dex register encoding. - Update compiler/optimizing/stack_map_test.cc.

Create OatFileAssistant class for assisting with oat files. The oat file assistant is used for determining whether dex2oat or patchoat is needed, for running dex2oat or patchoat as needed to make an oat file up to date, and to load dex files associated with a given dex location. The introduction of the OatFileAssistant class is meant to clean up and consolidate code related to the management of oat files that was duplicated and spread across dalvik_system_DexFile.cc and class_linker.cc.

dex2oat: Pack likely-dirty objects together when generating the boot image This introduces a new algorithm into image writer which "bins" objects by how likely they are to be dirtied at runtime. Objects in the same bin are placed contiguously in memory (i.e. into the same page). We try to tune the bin selection based on how clean or how dirty the object will likely be at runtime. As-is, this saves about 150KB per-process (private-dirty pages) and 700KB in zygote (shared-dirty). There is still about 800KB of objects that are clean but located in dirty pages, so with more analysis we can tune the bin selection and get even more memory savings.

Improve dex location canonicalization-related performance. Eagerly add canonical dex file locations to the OatFile's primary lookup map in Setup(). This moves the boot.oat work from every app startup to the zygote initialization. Since we always ended up initializing the canonical location map anyway due to the way that we're loading dex files, the lazy initialization didn't save anything. Clean up dex file name canonicalization to make sure we free() the memory returned by realpath() rather than using std::unique_ptr<> with the default deleter. Avoid some unnecessary duplicate OatDexFile lookups.

Reduce and speed-up class def searches. Use the class linker for descriptor lookups from the compile driver so that dex caches are populated. Reduce the scope of functions for scanning class paths to just the class linker where they are performed. If we see more than a threshold number of find class def misses on a dex file lazily compute an index, so that future lookups are constant time (part of the collection code is taken from https://android-review.googlesource.com/#/c/103865/3). Note that we take a lazy approach so that we don't serialize on loading dex files, this avoids the reason the index was removed in 8b2c0b9abc3f520495f4387ea040132ba85cae69. Remove an implicit and unnecessary std::string creation for PrintableString. Single threaded interpret-only dex2oat performance is improved by roughly 10%.

If we see more than a threshold number of find class def misses on a dex file lazily compute an index, so that future lookups are constant time (part of the collection code is taken from https://android-review.googlesource.com/#/c/103865/3). Note that we take a lazy approach so that we don't serialize on loading dex files, this avoids the reason the index was removed in 8b2c0b9abc3f520495f4387ea040132ba85cae69. Remove an implicit and unnecessary std::string creation for PrintableString. Single threaded interpret-only dex2oat performance is improved by roughly 10%.

Avoid use of std::string where we have const char*. Removing the ClassHelper caused std::string creation for all calls to Class::GetDescriptor and a significant performance regression. Make the std::string an out argument so the caller can maintain it and its life time while allowing GetDescriptor to return the common const char* case. Don't generate GC maps when compilation is disabled. Remove other uses of std::string that are occuring on critical paths. Use the cheaper SkipClass in CompileMethod in CompilerDriver. Specialize the utf8 as utf16 comparison code for the common shorter byte encoding. Force a bit of inlining, remove some UNLIKELYs (they are prone to pessimizing code), add some LIKELYs. x86-64 host 1-thread interpret-only of 57 apks: Before: 29.539s After: 23.467s Regular compile: Before: 1m35.347s After: 1m20.056s Bug: 16853450 Change-Id: Ic705ea24784bee24ab80084d06174cbf87d557ad Conflicts: runtime/utils.cc

Emit CFI for x86 & x86_64 JNI compiler. Now for host-side x86 & x86_64 ART, we are able to get complete stacktrace with even mixed C/C++ & Java stack frames. Testing: 1. art/test/run-test --host --gdb [--64] --no-relocate 005 2. In gdb, run 'b art::Class_classForName' which is implementation of a Java native method, then 'r' 3. In gdb, run 'bt'. You should see stack frames down to main() Change-Id: I2d17e9aa0f6d42d374b5362a15ea35a2fce96302

ART: Native support for multidex Native support for zip files with multiple classesX.dex. Works by explicitly looking for those files in ascending order. As these files have no file system representation for themselves, introduce synthetic dex locations: the name of the originating file plus a colon plus the name of the dex file, e.g., test.jar:classes2.dex. Opening a zip dex file will return all dex files in this way. This keeps the changes to dex2oat minimal. To hide multidex/synthetic names from the Java layer, let the handle of dalvik.system.DexFile refer to a vector of DexFile objects. When opening a location, test possible synthetic names and add them to the vector. Thus, the original multidex jar in the classpath will be associated with all embedded dex files.

Object model changes to support 64bit. 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.

When we transition back to foreground, we copy back to a free-list backed space. Create a seperate non-moving space which only holds non-movable objects. This enables us to quickly wipe the current alloc space (DlMalloc / RosAlloc) when we transition to background. Added multiple alloc space support to the sticky mark sweep GC. Added a -XX:BackgroundGC option which lets you specify which GC to use for background apps. Passing in -XX:BackgroundGC=SS makes the heap compact the heap for apps which do not perceive jank. Results: Simple background foreground test: 0. Reboot phone, unlock. 1. Open browser, click on home. 2. Open calculator, click on home. 3. Open calendar, click on home. 4. Open camera, click on home. 5. Open clock, click on home. 6. adb shell dumpsys meminfo PSS Normal ART: Sample 1: 88468 kB: Dalvik 3188 kB: Dalvik Other Sample 2: 81125 kB: Dalvik 3080 kB: Dalvik Other PSS Dalvik: Total PSS by category: Sample 1: 81033 kB: Dalvik 27787 kB: Dalvik Other Sample 2: 81901 kB: Dalvik 28869 kB: Dalvik Other PSS ART + Background Compaction: Sample 1: 71014 kB: Dalvik 1412 kB: Dalvik Other Sample 2: 73859 kB: Dalvik 1400 kB: Dalvik Other Dalvik other reduction can be explained by less deep allocation stacks / less live bitmaps / less dirty cards.

Compacting collector. The compacting collector is currently similar to semispace. It works by copying objects back and forth between two bump pointer spaces. There are types of objects which are "non-movable" due to current runtime limitations. These are Classes, Methods, and Fields. Bump pointer spaces are a new type of continuous alloc space which have no lock in the allocation code path. When you allocate from these it uses atomic operations to increase an index. Traversing the objects in the bump pointer space relies on Object::SizeOf matching the allocated size exactly. Runtime changes: JNI::GetArrayElements returns copies objects if you attempt to get the backing data of a movable array. For GetArrayElementsCritical, we return direct backing storage for any types of arrays, but temporarily disable the GC until the critical region is completed. Added a new runtime call called VisitObjects, this is used in place of the old pattern which was flushing the allocation stack and walking the bitmaps. Changed image writer to be compaction safe and use object monitor word for forwarding addresses. Added a bunch of added SIRTs to ClassLinker, MethodLinker, etc.. TODO: Enable switching allocators, compacting on background, etc.. Bug: 8981901 Change-Id: I3c886fd322a6eef2b99388d19a765042ec26ab99

Support hardware divide instruction Bug: 11299025 Uses sdiv for division and a combo of sdiv, mul and sub for modulus. Only does this on processors that are capable of the sdiv instruction, as determined by the build system. Also provides a command line arg --instruction-set-features= to allow cross compilation. Makefile adds the --instruction-set-features= arg to build-time dex2oat runs and defaults it to something obtained from the target architecture. Provides a GetInstructionSetFeatures() function on CompilerDriver that can be queried for various features. The only feature supported right now is hasDivideInstruction(). Also adds a few more instructions to the ARM disassembler b/11535253 is an addition to this CL to be done later. Change-Id: Ia8aaf801fd94bc71e476902749cf20f74eba9f68

Fix a DCHECK failure due to unmatching numbers of cards scanned. - See the bug for details of the failure. - After a discussion, we decided to get rid of the DCHECK as a simple solution would not detect corner failure cases and a full solution would add undesired complexity, and left a comment that explains what situation had caused a DCHECK failure. - Fix a potential error of failing to scan the last card that the end of the image space falls on as a result of the image end being not necessarily aligned by the card size. - Remove dead/unused MarkSweep::ScanRoot(). - Add AlignUp and AlignDown for aligning pointers.

Fix non concurrent GC ergonomics. If we dont have concurrent GC enabled, we need to force GC for alloc when we hit the maximum allowed footprint so that our heap doesn't keep growing until it hits the growth limit. Refactored a bit of stuff. Change-Id: I8eceac4ef01e969fd286ebde3a735a09d0a6dfc1

GC data structures allocation tracking Adds a new stl compatible allocator that is used in most GC data structures. When the data structures allocate and free memory, it lets the heap know of how much memory was allocated or freed. Using this info, we dump the approximated stl data structures memory usage when a sigquit occurs. The allocation tracking can be disabled with a compile time boolean flag to remove performance impact. Change-Id: Idddb6713169e07be913bceeb50f305c8573e4392

Create separate Android.mk for main build targets The runtime, compiler, dex2oat, and oatdump now are in seperate trees to prevent dependency creep. They can now be individually built without rebuilding the rest of the art projects. dalvikvm and jdwpspy were already this way. Builds in the art directory should behave as before, building everything including tests. Change-Id: Ic6b1151e5ed0f823c3dd301afd2b13eb2d8feb81
