Print more info in MarkSweep::VerifyRoot Refactored old root callback to use a new class called RootInfo. RootInfo contains all the relevant info related to the root associated with the callback. The MarkSweep::VerifyRoot function now uses this info to print the StackVisitor's described location if the GC root is of the type kRootJavaFrame. Some other cleanup. Example output: E/art (12167): Tried to mark 0x123 not contained by any spaces E/art (12167): Attempting see if it's a bad root E/art (12167): Found invalid root: 0x123 with type RootJavaFrame E/art (12167): Location=Visiting method 'void java.lang.Runtime.gc()' at dex PC 0xffffffff (native PC 0x0) vreg=0 Bug: 18588862 Change-Id: Ic5a2781f704e931265ffb3621c2eab4b2e25f60f

Remove object_utils.h. Break into object_lock, field_helper and method_helper. Clean up header files following this. Also tidy some of the Handle code in response to compiler errors when resolving the changes in this CL. Change-Id: I73e63015a0f02a754d0866bfaf58208aebcaa295

Change MethodHelper to use a Handle. Added ConstHandle to help prevent errors where you modify the value stored in the handle of the caller. Also fixed compaction bugs related to not knowing MethodHelper::GetReturnType can resolve types. This bug was present in interpreter RETURN_OBJECT.

Change root visitor to use Object**. Simplifies code and improves the performance of root visiting since we usually don't need to check to see if the object moved. Change-Id: Iba998f5a15ae1fa1b53ca5226dd2168a411196cf

Add root types and thread id to root visiting. Enables us to pass the root type and thread id to hprof. Bug: 12680863 Change-Id: I6a0f1f9e3aa8f9b4033d695818ae7ca3460d67cb

Enable moving classes. Slight reduction in Zygote size, memory savings are in the noise. Before: Zygote size: 8739224 After: Zygote size: 8733568 Fixed a bug where we didn't set the concurrent start bytes after switching the allocator from bump pointer to ROSAlloc in the zygote. This caused excessive memory usage. Added the method verifiers as roots to fix an issue caused by RegTypes holding a Class*. Added logic to clear card table in the SemiSpace collector, this reduces DalvikOther from ~2400k -> ~1760k when using the SemiSpace collector. Added a missing lock to the timing loggers which caused a rare one time crash in std::set. Bug: 11771255 Bug: 8499494 Bug: 10802951 Change-Id: I99d2b528cd51c1c5ed7012e3220b3aefded680ae

Add support for changing roots through the root visitor callback. Needed for copying collectors. Change-Id: Icc4a342a57e0cfb79587edb02ef8c85e08808877

Prevent segvs in JNI. A segv in JNI code (without CheckJNI) is hard to debug as we fail to see stacks, pending exceptions.. Make JNI code robust to null arguments, but don't go to the lengths that CheckJNI does in also sanity checking arguments, the priority here is just to stop the VM from crashing. Bug 10305723 Also, allow an unknown throw location not to crash exception dumping. Found/useful for debugging bug 10331039. (cherry picked from commit bc939663ccfbe0c648dd6a3670041510aca82420) Change-Id: Id0203db7d9e320d45ae5ba25d2b63939c79e5c16

Refactor java.lang.reflect implementation 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 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
