* Fix byte and char Get32Mathieu Chartier2015-03-061-4/+4
| | | | | | | | | | | 8 bit and 16 bit fields aren't necessarily 32 bit aligned due to field packing. This was causing SIGBUS for hprof dumping some apps. Bug: 19627999 (cherry picked from commit 2ff8da6a4d44bcf6a72dca1b5294a72297c5ce26) Change-Id: If549412fc4d62c55bb6a46f11658fc60b822a27e

* Clean up the locks around Heap::VisitObjects().Hiroshi Yamauchi2015-01-201-11/+5
| | | | | | | | This is so that we could support suspending all threads when visiting objects in the presence of a concurrent, moving collector. Bug: 12687968 Change-Id: Icc8e60630465afde948ebc6ea91d4ebaff5d7837
* Print more info in MarkSweep::VerifyRootMathieu Chartier2015-01-151-7/+7
| | | | | | | | | | | | | | | | | | | | | | | 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 (cherry picked from commit 12f7423a2bb4bfab76700d84eb6d4338d211983a) Bug: 18588862 Change-Id: Ic5a2781f704e931265ffb3621c2eab4b2e25f60f
* ART: Hprof cleanupAndreas Gampe2015-01-131-673/+705
| | | | | | | | Refactor things a bit to make it easier to stream. Add a simple test that dumps the heap and runs hprov-conf on it. Change-Id: I79a9ad37d4cf41fa8d63d039586aa80394d96005
* Change hprof to use streamingMathieu Chartier2015-01-091-273/+300
| | | | | | | | | | | | | | | Previously, we compute the whole hprof dump in memory resulting in > 50MB of memory usage for some apps (such as maps). This could cause the app to get killed by the low memory killer. The solution works by doing the dump in 2 passes. The first pass calculates the size of the dump. The second pass starts by sending the DDMS header with the correct size, then does the rest of the hprof dump by streaming and sending data one HprofRecord at a time.

* ART: Track Flush & Close in FdFileAndreas Gampe2014-11-181-2/+7
| | | | | | | | | | | | | | Implement a check that aborts when a file hasn't been explicitly flushed and closed when it is destructed. Add WARN_UNUSED to FdFile methods. Update dex2oat, patchoat, scoped_flock and some gtests to pass with this. (cherry picked from commit 9433ec60b325b708b9fa87e699ab4a6565741494) Change-Id: I9ab03b1653e69f44cc98946dc89d764c3e045dd4
* ART: Replace COMPILE_ASSERT with static_assert (runtime)Andreas Gampe2014-11-031-2/+2
| | | | | | Replace all occurrences of COMPILE_ASSERT in the runtime tree. Change-Id: I01e420899c760094fb342cc6cb9e692dd670a0b2
* Enable -Wimplicit-fallthrough.Ian Rogers2014-10-091-2/+2
| | | | | | | | Falling through switch cases on a clang build must now annotate the fallthrough with the FALLTHROUGH_INTENDED macro. Bug: 17731372 Change-Id: I836451cd5f96b01d1ababdbf9eef677fe8fa8324

* Fix identifier size in the heap dump.Calin Juravle2014-07-171-2/+6
| | | | | | | | | We're using addresses as IDs and previously we would have written sizeof(void*) as the identifier size in the header. Heap references are actually uint32_t so writting 4 bytes should be enough. Bug: 16016862 Change-Id: I785abf5030681b6009370b7b2d7552e8b4b54e67
* Remove object_utils.h.Ian Rogers2014-07-161-1/+0
| | | | | | | | | 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

* Now we have a proper C++ library, use std::unique_ptr.Ian Rogers2014-05-191-1/+1
| | | | | | | Also remove the Android.libcxx.mk and other bits of stlport compatibility mechanics. Change-Id: Icdf7188ba3c79cdf5617672c1cfd0a68ae596a61
* Avoid marking old class linker and intern table roots during pause.Mathieu Chartier2014-03-041-1/+1
| | | | | | | | | | | | | | | | | | | | The new root visiting logic has a concept of a root log which holds new roots which were added since the start of the GC. This is an optimization since it lets us only mark these newly added roots during the pause (or pre-cleaning) since the other roots intern table and class linker roots were marked concurrently at the start of the GC. Before (EvaluateAndApplyChanges): MarkConcurrentRoots: Sum: 605.193ms After: MarkConcurrentRoots: Sum: 271.858ms This should also reduce pathological GC pauses which used to be able to happen when the intern table or class linker became "dirty" during the concurrent GC.

* Change root visitor to use Object**.Mathieu Chartier2014-02-181-5/+5
| | | | | | | 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.Mathieu Chartier2014-02-111-19/+12
| | | | | | | Enables us to pass the root type and thread id to hprof. Bug: 12680863 Change-Id: I6a0f1f9e3aa8f9b4033d695818ae7ca3460d67cb
* Object model changes to support 64bit.Ian Rogers2014-02-061-84/+96
| | | | | | | | | | | | | | | | | | | | | | | 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

* Add support for changing roots through the root visitor callback.Mathieu Chartier2013-09-131-4/+4
| | | | | | Needed for copying collectors. Change-Id: Icc4a342a57e0cfb79587edb02ef8c85e08808877
* Refactor java.lang.reflect implementationBrian Carlstrom2013-08-131-5/+4
| | | | | | | | | | | 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 Carlstrom2013-07-122-0/+1120
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
