* Add native memory accounting through custom allocator.Mathieu Chartier2014-08-291-1/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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)
* Reduce time and memory usage of GVN.Vladimir Marko2014-07-311-0/+1
| | | | | | | | Filter out dead sregs in GVN. Reclaim memory after each LVN in the GVN modification phase. Bug: 16398693 Change-Id: I8c88c3009663754e1b66c0ef3f62c3b93276e385
* Faster deduplication in OatWriter.Vladimir Marko2014-07-091-7/+24
| | | | | | | | Use lower_bound() to look for duplicates and use it as a hint for insertion of new entries. Add a few useful functions to SafeMap<>. Change-Id: If7eab3f5d153be6e0d7ae040929849f1a636ee29
* Improve tracking of memory locations in LVN.Vladimir Marko2014-05-291-0/+3
| | | | | | | | | | | Rewrite the tracking of values stored in memory to allow recognizing the same value after storing it in memory and loading it back to vreg. Drop reliance on value name ordering for memory versioning in preparation for GVN. Also fix a few minor issues in LVN. Change-Id: Ifabe2d47d669d9ec43942cea6fd157e41af77ec8
* 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
* Create a scoped arena allocator and use that for LVN.Vladimir Marko2014-03-061-4/+11
| | | | | | | | | | | | This saves more than 0.5s of boot.oat compilation time on Nexus 5. TODO: Move other stuff to the scoped allocator. This CL alone increases the peak memory allocation. By reusing the memory for other parts of the compilation we should reduce this overhead. Change-Id: Ifbc00aab4f3afd0000da818dfe68b96713824a08

* GC data structures allocation trackingMathieu Chartier2013-07-251-3/+5
| | | | | | | | | | | | | Adds a new stl compatible allocator that is used in most GC data structures. When the data structures allocate and free memory, it lets the heap know of how much memory was allocated or freed. Using this info, we dump the approximated stl data structures memory usage when a sigquit occurs. The allocation tracking can be disabled with a compile time boolean flag to remove performance impact. Change-Id: Idddb6713169e07be913bceeb50f305c8573e4392
* Fix multiple inclusion guards to match new pathnamesBrian Carlstrom2013-07-171-3/+3

* Create separate Android.mk for main build targetsBrian Carlstrom2013-07-121-0/+105
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
