* Change IsMethodTracingActive to GetMethodTracingMode.Jeff Hao2013-08-301-2/+3
| | | | | | | | | | This allows traceview to tell whether tracing is active, and whether it is sampling or method tracing. Bug: 9968521 Change-Id: I72100d1536ea3168998110ec1cfa5a183b55a67c (cherry picked from commit 9d3a0a2e253aecd07c4a053c19cf9b0ccaa2db49)
* Add support for sample profiling in traceview.Jeff Hao2013-08-281-1/+5
| | | | | | | | | | Instead of method instrumentation, allow traceview to periodically sample stack traces of threads. Disabled by default until we add gui support for this new mode. (cherry picked from commit 676f8a527fb62abd39663d55c7d9208f5ca03093) Change-Id: Ia5d0d57012305a5830d042bcb903a429432b035b

* [X86] X86 trace JIT compiler supportDong-Yuan Chen2012-07-201-19/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch provides a fully functional x86 trace JIT compiler for Dalvik VM. It is built on top of the existing x86 fast interpreter with bug fixes and needed extension to support trace JIT interface. The x86 trace JIT code generator was developed independent of the existing template-based code generator and thus does not share exactly the same infrastructure. Included in this patch are: * Deprecated and removed the x86-atom fast interpreter that is no longer functional since ICS. * Augmented x86 fast interpreter to provide interfaces for x86 trace JIT compiler. * Added x86 trace JIT code generator with full JDWP debugging support. * Method JIT and self-verification mode are not supported. The x86 code generator uses the x86 instruction encoder/decoder library from the Apache Harmony project. Additional wrapper extension and bug fixes were added to support the x86 trace JIT code generator. The x86 instruction encoder/decoder is embedded inside the x86 code generator under the libenc subdirectory.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (cherry-picked from master) When a resume attempt is cancelled due to other pending request make sure the old native resume PC is cleared. Otherwise the JIT code cache may be re-entered with mismatching Dalvik PC. Also fix a code bloat problem where single-step count is not set properly after executing a return instruction.

* Interpreter/Debugger fix #4479968buzbee2011-05-251-1/+1
| | | | | | | | | | | | | | | | | | | | | | This one was tricky to track down. The underlying problem arose with the consolidation of InterpState with Thread. Rather than having a state structure for each instance of the interpreter, we moved to a model that had a single thread-local struct shared by all interpreter instances running on that thread. A portion of interpreter state can't be shared - and thus was saved and restored on nested invocations of the interpreter. The bug here was that the storage for method return values was not included in the state that needed save/retore. In normal operation, it doesn't need to be saved - that storage isn't live across an invoke that could trigger a nested interpreter activation. However, when debugging, the debugger itself may hijack threads and create new interpreter instances for its own purposed - and there is a small window in which live retval can be trashed. The fix is simply to move retval into the InterpSave struct. Change-Id: Ib621824b799c5caa16fdfa8f5689a181159059df
* Another single-stepping fix in JIT self-verification mode.Ben Cheng2011-05-111-2/+2
| | | | | | | | | | The counted single stepping check should be based on the kSubModeCountedStep submode instead. Also since the NPC value is cleared when exceptions are thrown, we can single-step instructions that can throw as well. Change-Id: Idbc1307ae0956016ef76186aebc6e3b89b119d9d

| | | | | | | | | | | | Replace dvmUpdateInterpBreak() and friends with more direct enable/disable subMode calls. Hide breakFlags manipulation from higher-level callers and infer what is needed from the active subMode.

* InterpBreak cleanup (part 1)buzbee2011-04-221-24/+7
| | | | | | | | | Moved the suspend count variables from the interpBreak structure. These are already protected by a mutex, and we need the space in interpBreak for additional subMode flags. This CL just does the move and expands the width of subMode to 16-bits. Change-Id: I4a6070b1ba4fb08a0f6e0aba6f150b30f9159eed
