* Move mirror::ArtMethod to nativeMathieu Chartier2015-06-021-6/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Optimizing + quick tests are passing, devices boot. TODO: Test and fix bugs in mips64. Saves 16 bytes per most ArtMethod, 7.5MB reduction in system PSS. Some of the savings are from removal of virtual methods and direct methods object arrays. Bug: 19264997 (cherry picked from commit e401d146407d61eeb99f8d6176b2ac13c4df1e33) Change-Id: I622469a0cfa0e7082a2119f3d6a9491eb61e3f3d Fix some ArtMethod related bugs Added root visiting for runtime methods, not currently required since the GcRoots in these methods are null. Added missing GetInterfaceMethodIfProxy in GetMethodLine, fixes --trace run-tests 005, 044. Fixed optimizing compiler bug where we used a normal stack location instead of double on ARM64, this fixes the debuggable tests. TODO: Fix JDWP tests. Bug: 19264997 Change-Id: I7c55f69c61d1b45351fd0dc7185ffe5efad82bd3 ART: Fix casts for 64-bit pointers on 32-bit compiler. Bug: 19264997 Change-Id: Ief45cdd4bae5a43fc8bfdfa7cf744e2c57529457 Fix JDWP tests after ArtMethod change Fixes Throwable::GetStackDepth for exception event detection after internal stack trace representation change. Adds missing ArtMethod::GetInterfaceMethodIfProxy call in case of proxy method. Bug: 19264997 Change-Id: I363e293796848c3ec491c963813f62d868da44d2 Fix accidental IMT and root marking regression Was always using the conflict trampoline. Also included fix for regression in GC time caused by extra roots. Most of the regression was IMT. Fixed bug in DumpGcPerformanceInfo where we would get SIGABRT due to detached thread. EvaluateAndApplyChanges: From ~2500 -> ~1980 GC time: 8.2s -> 7.2s due to 1s less of MarkConcurrentRoots Bug: 19264997 Change-Id: I4333e80a8268c2ed1284f87f25b9f113d4f2c7e0 Fix bogus image test assert Previously we were comparing the size of the non moving space to size of the image file. Now we properly compare the size of the image space against the size of the image file. Bug: 19264997 Change-Id: I7359f1f73ae3df60c5147245935a24431c04808a [MIPS64] Fix art_quick_invoke_stub argument offsets. ArtMethod reference's size got bigger, so we need to move other args and leave enough space for ArtMethod* and 'this' pointer. This fixes mips64 boot.

* ART: Clean up arm64 kNumberOfXRegisters usage.Vladimir Marko2015-05-261-0/+1
| | | | | | | | | | | | | | | | | | | | | Avoid undefined behavior for arm64 stemming from 1u << 32 in loops with upper bound kNumberOfXRegisters. Create iterators for enumerating bits in an integer either from high to low or from low to high and use them for <arch>Context::FillCalleeSaves() on all architectures. Refactor runtime/utils.{h,cc} by moving all bit-fiddling functions to runtime/base/bit_utils.{h,cc} (together with the new bit iterators) and all time-related functions to runtime/base/time_utils.{h,cc}. Improve test coverage and fix some corner cases for the bit-fiddling functions.

* API change in StackVisitor::GetVReg*.Nicolas Geoffray2015-03-131-2/+5
| | | | | | | | | | - Remove GetVReg() and SetVReg() that were expecting to always succeed. - Change Quick-only methods to take a FromQuickCode suffix. - Change deopt to use dead values when GetVReg does not succeed: the optimizing compiler will not have a location for uninitialized Dex registers and potentially dead registers.

| | | | | | | | | | The thread doing the suspension doesn't attempt to suspend the other thread unless it knows another thread isn't trying to suspend it. Use the suspend count, and its lock, for this purpose. Re-enable ThreadStress test. Bug: 15446488 Change-Id: Idd34410c7b89d8abd6973e5699a15ca699472c78

* Add GcRoot to clean up and enforce read barriers.Hiroshi Yamauchi2014-07-291-4/+4
| | | | | | | | | | | | | Introduce a value-type wrapper around Object* for GC roots so that 1) we won't have to directly add the read barrier code in many places and 2) we can avoid accidentally bypassing/missing read barriers on GC roots (the GcRoot interface ensures that the read barrier is executed on a read). The jdwp test passed. Bug: 12687968 Change-Id: Ib167c7c325b3c7e3900133578815f04d219972a1

* Recycle mem-maps for collector transitions.Mathieu Chartier2014-07-221-2/+2
| | | | | | | | | | | | | | | | | | | | We now create spaces when we need them for collector transitions or homogeneous compaction by recycling mem maps. Change the bump pointer space size to be as large as the heap capacity instead of 1/2 heap capacity like it used to be. For GSS, bump pointer spaces are set to 32MB currently. Changed GSS to have main space == non moving space since we don't need to copy from the main space. Fixes GC stress tests 074, 096. Fixed test 080 oom throw with -Xmx2m for GC stress test, this was broken since it was allocating a 4 MB array before starting the OOM process.

* Use sched_yield in Monitor::MonitorEnter.Mathieu Chartier2014-07-151-1/+5
| | | | | | | | | | | | | | | | | | | Previously we used NanoSleep(1000), but this was unreliable. It could result in waiting for >= 40ms instead of 1us. Since this was in a loop it was especially bad if the GC was trying to suspend all the threads when we were sleeping. This resulted in thread suspension occasionally taking longer than a second. Results on the provided picasso-sample app on Nexus 5: Longest GC pause before: ~1.5s. Longest GC pause after: <5ms. Also added a warning if thread suspension takes longer than a threshold (currently 5ms).

* Use memory chunks for monitors on LP64Andreas Gampe2014-07-101-12/+45
| | | | | | | | | | | | | | 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
* ART: Update Monitor::Wait so it releases monitor_lock_ before throwing an ↵Elena Sayapina2014-07-071-3/+4
| | | | | | | | | | | | | exception Thread should release monitor_lock_ Mutex (which guards shared structures behind Java monitor) in Monitor::Wait before throwing any exception. Otherwise the thread may be suspended by GC during that time still holding the lock. This may cause deadlock during GC in case some other thread needs to acquire the monitor_lock_. The other thread can't be suspended by GC then waiting for exclusive lock and "thread suspend timeout" occurs.

* Clean up and augment Atomic class. Replace QuasiAtomic MemBars.Hans Boehm2014-06-061-1/+1
| | | | | | | | | | | | | | | | | | Add a number of missing C++11 operations to Atomic class. Invoke the 64 bit routines in QuasiAtomic when necessary. Replace QuasiAtomic membars with fences that correspond to C++11 fences. QuasiAtomic was moved to the top of the file. Only fence implementations actually changed. This replaces some buggy uses of MembarStoreStore, as reported in b/14685856 . Avoid some redundant fences for long volatile operations. Incompletely converts low-level memory access operations to Atomic. Change-Id: Iea828431a0cea46540eb74fcaa02071cab6fdcda
