* Add handler for printing java stack traces for compiled code SIGSEGV.Mathieu Chartier2014-04-0110-74/+148
| | | | | | | | | | | Added a new FaultHandler which attempts to print a java stack trace when a SIGSEGV occurse in generated code. This should help debugging compiler and GC related heap corruption. Bug: 13725693 Bug: 12934910 Change-Id: Id54d83ea180c222eb86d449c61926e83f0b026ad

| * Fix stack overflow slow path error.Mathieu Chartier2014-03-311-1/+1
| | | | | | | | | | | | | | | | | | | | The frame size without spill was being passed into the slow path instead of the spill size. This was incorrect since only the spills will have been pushed at the point of the overflow check. Also addressed an other comment. Change-Id: Ic6e455122473a8f796b291d71f945bcf72788662

* | | Implement implicit stack overflow checksDave Allison2014-03-317-25/+308
| |/ |/| | | | | | | | | | | | | | | | | | | | | | | This also fixes some failing run tests due to missing null pointer markers. The implementation of the implicit stack overflow checks introduces the ability to have a gap in the stack that is skipped during stack walk backs. This gap is protected against read/write and is used to trigger a SIGSEGV at function entry if the stack will overflow. Change-Id: I0c3e214c8b87dc250cf886472c6d327b5d58653e

This also significantly simplifies GC code. No measured performance impact on benchmarks, but this should slightly increase sticky GC throughput. Changed RevokeRosAllocThreadLocalBuffers to happen at most once per GC. Previously it occured twice if pre-cleaning was enabled. Renamed HandleDirtyObjectsPhase to PausePhase and enabled it for non-concurrent GC. This helps reduce duplicated code which was in both HandleDirtyObjectsPhase for concurrent GC and ReclaimPhase for non-concurrent GC. Change-Id: I533414b5c2cd2800f00724418e0ff90e7fdb0252

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When installing/uninstalling a breakpoint in a method, we fully or selectively deoptimize/undeoptimize depending on whether the method can be inlined. When the method can be inlined, it requires full deoptimization. Otherwise, it only requires selective deoptimization. We add sanity check to control we are in a consistent state each time we add or remove a breakpoint. We also add some comments to better describe the process of deoptimization for breakpoint.

We move deoptimization-related information to Dbg class only (deoptimization request queue, full deoptimization event count and deoptimization lock). We replace MethodInstrumentionRequest by DeoptimizationRequest. This is used to know which kind of deoptimization is required for a particular event. It also simplifies lock ordering a bit during event setup: we no longer need to hold the deoptimization lock while holding the breakpoint lock. Moreover, the deoptimization lock should be held only after the event list lock. Bug: 12187616 Change-Id: Iff13f004adaeb25e5d609238bacce0b9720510e6
