* Add support for sample profiling in traceview.Jeff Hao2013-08-281-0/+1
| | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | In dalvik, most function names start with "dvm" except dmvCompilerTemplateEnd. Convert it to dvmCompilerTemplateEnd in order to follow the rule. Change-Id: I09c41f8c9d55058013fbdb62ac5922ccd067ce39

| | | | | | | | | | | | | | | | | | | | Found by someone reading the code, rather than because we saw a crash.

* InterpBreak cleanup (part 1)buzbee2011-04-221-35/+28
| | | | | | | | | 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
* Consolidate curFrame fields in thread storagebuzbee2011-04-221-4/+4
| | | | | | | We ended up with two locations in the Thread structure for saved Dalvik frame pointer. This change consolidates them. Change-Id: I78f288e4e57e232f29663be930101e775bfe370f
* Remove DVM_LOCK_INIT and DVM_LOCK_INITIAL_THIN_VALUE.Carl Shapiro2011-04-201-1/+0
| | | | | | | | | | | | The original implementation for thin locks used a magic non-zero value to encode the initial thin lock state. This magic value was kept around in DVM_LOCK_INITIAL_THIN_VALUE and stored into the lock word of newly allocated objects. A later revision to the thin locking code made the initial thin lock value be 0. That change eliminated the requirement that lock words be explicitly initialized as the allocator always returns zero-filled memory. Change-Id: I34e0b43b4c4db0f45cf7cf524e15d4a6096c1365
