* Let classloader provide correct LD_LIBRARY_PATHDmitriy Ivanov2015-06-091-1/+1
| | | | | | | | | Rely on BaseDexClassLoader to provide correct LD_LIBRARY_PATH Bug: http://b/21647354 Bug: http://b/21667767 Bug: http://b/8076853 Change-Id: I8c690a2578d5de43be9da964fa5a4c0246aa6eec
* Use runFinalizationWithTimeout for native allocationsMathieu Chartier2015-06-051-0/+5
| | | | | | | | Prevents deadlocks by not waiting longer than 250ms for finalizers to complete. Bug: 21544853 Change-Id: I57b2f7ae8b74185922eb3c15ba0ab71a4d2348aa

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. Bug: 19264997 Change-Id: I47198d5f39a4caab30b3b77479d5eedaad5006ab
* Replace String CharArray with internal uint16_t array.Jeff Hao2015-04-271-0/+131
| | | | | | | | | | | | Summary of high level changes: - Adds compiler inliner support to identify string init methods - Adds compiler support (quick & optimizing) with new invoke code path that calls method off the thread pointer - Adds thread entrypoints for all string init methods - Adds map to verifier to log when receiver of string init has been copied to other registers. used by compiler and interpreter Change-Id: I797b992a8feb566f9ad73060011ab6f51eb7ce01
* Fix reflection handling and test flakinessMathieu Chartier2015-04-231-0/+2
| | | | | | | | | | | | Fixed reflection invoke to handle exceptions which occur from FindClass or NewObject by throwing these instead of the expected InvocationTargetException. Added test case to 080 for this reflection invoke. Fixed println throwing OOM in 104-growth-limit. Change-Id: I65766e7c3478e299da06fdc3a521fe3f3e8fdba9

* Add AccessibleObject and Field to mirrorMathieu Chartier2015-03-291-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Main motivation is to remove all the functionality / field access on java side to ArtField. Also comes with some reflection speedups / slowdowns. Summary results: getDeclaredField/getField are slower mostly due to JNI overhead. However, there is a large speedup in getInt, setInt, GetInstanceField, and GetStaticField. Before timings (N5 --compiler-filter=everything): benchmark ns linear runtime Class_getDeclaredField 782.86 === Class_getField 832.77 === Field_getInt 160.17 = Field_setInt 195.88 = GetInstanceField 3214.38 ============== GetStaticField 6809.49 ============================== After: Class_getDeclaredField 1068.15 ============ Class_getField 1180.00 ============== Field_getInt 121.85 = Field_setInt 139.98 = GetInstanceField 1986.15 ======================= GetStaticField 2523.63 ============================== Bug: 19264997 Change-Id: Ic0d0fc1b56b95cd6d60f8e76f19caeaa23045c77
* Add paths to apk!lib/<abi> to LD_LIBRARY_PATHDmitriy Ivanov2015-03-231-1/+1
| | | | | | | | Add paths to .apk to LD_LIBRARY_PATH to enable bionic linker's "open from zip-file" feature. Bug: 8076853 Change-Id: I1aa2c039bb2a590ae72f256acc9ba5401c2c59b1
* ART: Move DexFile vector to Java arrayAndreas Gampe2015-02-241-1/+1
| | | | | | | | To avoid having native vectors only referenced by Java objects, which look like leaks to Valgrind, use a Java array to store references to native DexFile objects. Change-Id: If3c2b31b9d0914ed1965cfd5e3fdb94ea41b1477
* Move GC daemon locking logic into heapMathieu Chartier2014-12-151-2/+0
| | | | | | | | Fixes deadlock caused by acquirng the mutator lock while synchronizing on the daemon thread. Bug: 18739541 Change-Id: I925b8f0f3b58178da6eff17b9c073f655c39597b
* Stop daemon threads in runtime shutdownMathieu Chartier2014-12-101-0/+2
| | | | | | | | | | | | Ensure that daemons are stopped and joins before bringing down the runtime. This fixes bugs related to native code still running when we shutdown the runtime. Also changed the mutex destructor to allow contenders if we are deleting a monitor lock level mutex. Bug: 18577101 Change-Id: I6457b35fd69c6997b9003b5f15f39861749843a9

| * More use of WellKnownClasses for debuggerSebastien Hertz2014-10-231-0/+10
| | | | | | | | | | | | | | | | | | Uses WellKnownClasses cached fields for ThreadGroupReference-related JDWP commands. Adds fields of java.lang.ThreadGroup and java.util.ArrayList used by the debugger. Change-Id: I54f7ef7e44cb61bec95657a69177bba1fbb7dc75
* | Tidy up logging.Ian Rogers2014-10-221-0/+2
|/ | | | | | | | | | | | | | | | | Move gVerboseMethods to CompilerOptions. Now "--verbose-methods=" option to dex2oat rather than runtime argument "-verbose-methods:". Move ToStr and Dumpable out of logging.h, move LogMessageData into logging.cc except for a forward declaration. Remove ConstDumpable as Dump methods are all const (and make this so if not currently true). Make LogSeverity an enum and improve compile time assertions and type checking. Remove log_severity.h that's only used in logging.h. With system headers gone from logging.h, go add to .cc files missing system header includes. Also, make operator new in ValueObject private for compile time instantiation checking. Change-Id: I3228f614500ccc9b14b49c72b9821c8b0db3d641
* ART: Fix some -Wpedantic errorsAndreas Gampe2014-09-291-8/+9
| | | | | | | | | | | | | | | | Remove extra semicolons. Dollar signs in C++ identifiers are an extension. Named variadic macros are an extension. Binary literals are a C++14 feature. Enum re-declarations are not allowed. Overflow. Change-Id: I7d16b2217b2ef2959ca69de84eaecc754517714a

| | | | | | | | | | | | Restore init of WellKnownClasses::org_apache_harmony_dalvik_ddmc_Chunk_data and removed duplicated line. Bug: 17467328 Bug: 17463118 (cherry picked from commit 96cd6714d94b47512710776761dec98c8be68bef) Change-Id: I9f225825bef4995460e1c79a9f3a6c1331f24201

| | | | | | | | | | stack overflow Bug: 17463118 (cherry picked from commit bfc2b98a3cf7a9d580f2477e54aabded5004fd26) Change-Id: Iea04bb7f6c4daa9cbdb8ee6ce8ddcbeb9f05aa3d
* Add fast path for FindClass using the type dex file.Mathieu Chartier2014-09-081-0/+16
| | | | | | | | | | | | | | | | | If we are using the PathClassLoader with a BootClassLoader parent, we can handle the common case in the FindClass function without needing to go back to java code. Around 10% speedup measured of maps launch, could be noise due to large variation of app launch times. Eliminates defineClassNative from being anywhere near the top of sampling profiles. Bug: 17397179 Bug: 16828525 (cherry picked from commit 8a39e7fe02e9a81853dc7a75cb50d9ece07a9b37) Change-Id: I1f31de76c1b1a53e32173b1e61a59b0e2f267c98
* ART: Throw StackOverflowError in native codeAndreas Gampe2014-07-211-0/+4
| | | | | | | | | | Initialize stack-overflow errors in native code to be able to reduce the preserved area size of the stack. Includes a refactoring away from constexpr in instruction_set.h to allow for easy changing of the values. Change-Id: I117cc8485f43da5f0a470f0f5e5b3dc3b5a06246
* Avoid some unnecessary use of stl types.Ian Rogers2014-05-151-0/+2
| | | | | | | May be a minor performance win but really done for libc++ as this removes a dependency on a library function whose prototype includes a std::string. Change-Id: Ifc07a9caef1206caf2a69a6e1b0bfc0ba56c8c62
* Object model changes to support 64bit.Ian Rogers2014-02-061-1/+1
| | | | | | | | | | | | | | | | | | | | | | | 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

| | | | | | | | | | | Cherry-picked from commit ed41d5c44299ec5d44b8514f6e17f802f48094d1. Move to ArtMethod/Field instead of AbstractMethod/Field and have java.lang.reflect APIs delegate to ArtMethod/ArtField. Bug: 10014286. Change-Id: Iafc1d8c5b62562c9af8fb9fd8c5e1d61270536e7

* Create separate Android.mk for main build targetsBrian Carlstrom2013-07-121-0/+206
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
