* Replace NULL with nullptrMathieu Chartier2015-04-221-1/+2
| | | | | | | Also fixed some lines that were too long, and a few other minor details. Change-Id: I6efba5fb6e03eb5d0a300fddb2a75bf8e2f175cb
* Reserve bits in the lock word for read barriers.Hiroshi Yamauchi2015-03-031-3/+5
| | | | | | | | | This prepares for the CC collector to use the standard object header model by storing the read barrier state in the lock word. Bug: 19355854 Bug: 12687968 Change-Id: Ia7585662dd2cebf0479a3e74f734afe5059fb70f
* Remove -Wno-unused-parameter and -Wno-sign-promo from base cflags.Ian Rogers2014-11-031-0/+3
| | | | | | | | | | | Fix associated errors about unused paramenters and implict sign conversions. For sign conversion this was largely in the area of enums, so add ostream operators for the effected enums and fix tools/generate-operator-out.py. Tidy arena allocation code and arena allocated data types, rather than fixing new and delete operators. Remove dead code. Change-Id: I5b433e722d2f75baacfacae4d32aef4a828bfe1b

* Add native memory accounting through custom allocator.Mathieu Chartier2014-08-291-2/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Added a custom allocator that lets you pass in a special tag which specifices where the allocation came from. This is used when dumping. The performance overhead is low since each allocation only does a atomic add/sub for each allocation/free. The measurements are dumped to traces.txt during SIGQUIT. Example output: I/art (27274): AllocatorTagHeap active=120 max=120 total=168 I/art (27274): AllocatorTagMonitorList active=1572 max=6240 total=11724 I/art (27274): AllocatorTagClassTable active=185208 max=185208 total=268608 I/art (27274): AllocatorTagInternTable active=430368 max=430368 total=436080 I/art (27274): AllocatorTagMaps active=5616 max=6168 total=34392 I/art (27274): AllocatorTagLOS active=1024 max=1536 total=2044 I/art (27274): AllocatorTagSafeMap active=0 max=51936 total=533688 I/art (27274): AllocatorTagLOSMaps active=144 max=1248 total=5760 I/art (27274): AllocatorTagReferenceTable active=10944 max=11840 total=19136 I/art (27274): AllocatorTagHeapBitmap active=32 max=40 total=56 I/art (27274): AllocatorTagHeapBitmapLOS active=8 max=8 total=8 I/art (27274): AllocatorTagVerifier active=0 max=18844 total=1073156 I/art (27274): AllocatorTagModUnionCardSet active=5300 max=5920 total=56020 I/art (27274): AllocatorTagModUnionReferenceArray active=24864 max=24864 total=24864 I/art (27274): AllocatorTagJNILibrarires active=320 max=320 total=320 I/art (27274): AllocatorTagOatFile active=1400 max=1400 total=5852 Change-Id: Ibb470ef2e9c9a24563bb46422d46a55799704d82 (cherry picked from commit 5369c40f75fdcb1be7a7c06db212ce965c83a164)
* Use memory chunks for monitors on LP64Andreas Gampe2014-07-101-19/+103
| | | | | | | | | | | | | | Monitor IDs in lock words are only 30b. On a 32b system that works fine, as memory is usually aligned enough that shifting works out. On 64b systems, the virtual memory space is too large for that. This adds memory chunks into which we allocate the monitors so that we have base_addr + offset and can use the offset as the monitor ID. To allow for relatively compact but growable storage, we use a list of chunks. Added a global lock for the monitor pool. Change-Id: I0e290c4914a2556e0b2eef9902422d7c4dcf536d
* Force inlining on trivial accessors.Ian Rogers2014-04-291-1/+2
| | | | | | | | | Make volatility for GetFieldObject a template parameter. Move some trivial mirror::String routines to a -inl.h. Bug: 14285442 Change-Id: Ie23b11d4f18cb15a62c3bbb42837a8aaf6b68f92

* Object model changes to support 64bit.Ian Rogers2014-02-061-0/+94
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
