* Move mirror::ArtMethod to nativeMathieu Chartier2015-06-021-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Optimizing + quick tests are passing, devices boot. 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
* Fix updating of JNI references for String.<init>.Jeff Hao2015-05-271-0/+3
| | | | | | | | Was missing updates to globals and weak globals. Bug: 21288130 Bug: 21440428 Change-Id: I5f801f68b61f6b066b441b92ace367e6ba434789
* Intercept JNI invocation of String.<init> methods.Jeff Hao2015-05-201-3/+3
| | | | | | | | | | | libmono uses JNI AllocObject and CallNonvirtualVoidMethod to create and initialize a string instead of using the recommended NewObject. This change adds an intercept to change the String.<init> call to a StringFactory call instead. Then, it uses the object id of the original string object referrer and maps it to the result of the StringFactory. Bug: 21288130 Change-Id: Ib4db402c178bc37188d5c5faf30b6e4fdc747b17

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add linear alloc. Moved ArtField to be native object. Changed image writer to put ArtFields after the mirror section.

* Fix some reflection errorsMathieu Chartier2015-03-291-1/+1
| | | | | | | | Fixed incorrectly using 2nd frame instead of 1st in VerifyAccess. Added regression test to ART. Fixed broken setShort, getDeclaredFieldInternal. Change-Id: I4b21d52d998cb768fe9503b8bccec506b7b972e5
* Add AccessibleObject and Field to mirrorMathieu Chartier2015-03-291-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
* Remove ThrowLocation.Nicolas Geoffray2015-03-101-4/+2
| | | | | | | Note that this is a cleanup change, and has no functionality change. The ThrowLocation had no use anymore. Change-Id: I3d2126af1dc673cec3a0453ff3d56a172663a5f6
* Remove MethodHelper.Ian Rogers2014-12-021-1/+0
| | | | | | | Move use as a shorty processor to only use in portable. Move GetNumberOfReferenceArgsWithoutReceiver to mirror::ArtMethod. Change-Id: I7ded3d05315c84bce4ab19cb330ef74289da4bb3
* Remove MethodHelper from the interpreter.Ian Rogers2014-12-021-1/+1
| | | | | | | | | Use ShadowFrame to get the executing method to avoid a handle for the current method. Various associated bits of header file clean-up and removal of an unnecessary use of MethodHelper in CompilerDriver. Change-Id: I3b6f4413701e8fc6b0c58b0041a0dd15472bedaa
* Make ART compile with GCC -O0 again.Ian Rogers2014-10-161-1/+1
| | | | | | | | | | | | | Tidy up InstructionSetFeatures so that it has a type hierarchy dependent on architecture. Add to instruction_set_test to warn when InstructionSetFeatures don't agree with ones from system properties, AT_HWCAP and /proc/cpuinfo. Clean-up class linker entry point logic to not return entry points but to test whether the passed code is the particular entrypoint. This works around image trampolines that replicate entrypoints.

* Optimize get/set reflection performanceMathieu Chartier2014-09-261-4/+5
| | | | | | | | | | | | | | Speedups mostly from reducing how often access checks are needed, and adding more inlining, and adding templates. Field_getInt from ~850ns -> 350ns. Field_setInt from ~900ns -> 370ns. Bug: 14063288 (cherry picked from commit ffc788cb7b5b9f53734d7bb8af2d5e45d885546b) Change-Id: I2441581ff3478c6ae43b6aa49939ff3f07555ec8
* Wire up check JNI force copy mode.Ian Rogers2014-08-081-0/+1
| | | | | | | | | | | | Increase check JNI checks. Break apart jni_internal.h in to jni_env_ext.h and java_vm_ext.h. Fix the abuse of ScopedObjectAccess/annotalysis by ScopedCheck in the case of VM routines. Make class loader override and shared library class loader JNI global references rather than mirror pointers. Clean-ups to native bridge. Change-Id: If7c6110b5aade7a402bfb67534af86a7b2cdeb55
* Don't get and restore thread state for ScopedFastNativeObjectAccess.Mathieu Chartier2014-05-191-7/+7
| | | | | | | Before we would ensure that we were runnable for fast native object access. However, these are done when you are already runnable. Change-Id: Ia4c6e4c83d146fe2a988b37b3133ca46b0f0fa42

* Add access checks to Method and Field reflection.Jeff Hao2014-03-281-1/+4
| | | | | | | Art side of this change. Has a corresponding libcore change. Bug: 13620925 Change-Id: Ie67f802a2a400e8212b489b9a261b7028422d8ba
* Reflection tidying.Ian Rogers2014-03-261-7/+4
| | | | | | | | Move out arguments to the right and make pointer not reference types. Remove unused unbox for argument routine. Simplify convert primitive routine for the case of identical types. Change-Id: I6456331b0f3f3e5f0b2c361a9f50b4ed1c9462a3
* Refactor reflective method invocation.Ian Rogers2014-03-141-2/+25
| | | | | | | | | | Move invocation code out of JNI internal into reflection, including ArgArray code. Make reflective invocation use the ArgArray to build arguments rather than allocating a jvalue[] and unboxing arguments into that. Move reflection part of jni_internal_test into reflection_test. Make greater use of fast JNI. Change-Id: Ib381372df5f9a83679e30e7275de24fa0e6b1057

* Create separate Android.mk for main build targetsBrian Carlstrom2013-07-121-0/+59
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
