* Move mirror::ArtMethod to nativeMathieu Chartier2015-06-021-5/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* ART: Clean up arm64 kNumberOfXRegisters usage.Vladimir Marko2015-05-261-288/+0
| | | | | | | | | | | | | | | | | | | | | 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.

* ART: Streaming trace modeAndreas Gampe2015-04-151-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | Add a streaming mode for tracing. Streaming uses a buffer of 16KB and writes to the output when that buffer gets full. Streaming mode can be enabled with -Xmethod-trace-stream and is currently not exposed otherwise. Add a python script that can parse the streaming format, which simply contains strings for newly encountered threads and methods inline, and create output that can be used with traceview. Add Trace::Pause and Trace::Abort, which can pause and abort tracing. Abort is different from Stop in that it does not write the data. Add code to the zygote hooks JNI implementation that pauses tracing before the fork, making sure that a child cannot clobber the parent's data. Add code to the zygote hooks JNI implementation that aborts old tracing and starts new tracing in the child after the fork. Currently base the output on the pid. This will not work on an unmodified device, as the profiles directory is not generally writable, but we do not have enough information at that point. Consider a scheme that restarts tracing later.

* ART: Fix IsInt when N==32, add testsDavid Brazdil2015-03-271-6/+11

* Unify ART's various implementations of bit_cast.Roland Levillain2015-03-241-13/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ART had several implementations of art::bit_cast: 1. one in runtime/base/casts.h, declared as: template <class Dest, class Source> inline Dest bit_cast(const Source& source); 2. another one in runtime/utils.h, declared as: template<typename U, typename V> static inline V bit_cast(U in); 3. and a third local version, in runtime/memory_region.h, similar to the previous one: template<typename Source, typename Destination> static Destination MemoryRegion::local_bit_cast(Source in); This CL removes versions 2. and 3. and changes their callers to use 1. instead. That version was chosen over the others as: - it was the oldest one in the code base; and - its syntax was closer to the standard C++ cast operators, as it supports the following use: bit_cast<Destination>(source) since `Source' can be deduced from `source'.

* | Compress the Dex register maps built by the optimizing compiler.Roland Levillain2015-03-121-0/+18
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Replace the current list-based (fixed-size) Dex register encoding in stack maps emitted by the optimizing compiler with another list-based variable-size Dex register encoding compressing short locations on 1 byte (3 bits for the location kind, 5 bits for the value); other (large) values remain encoded on 5 bytes. - In addition, use slot offsets instead of byte offsets to encode the location of Dex registers placed in stack slots at small offsets, as it enables more values to use the short (1-byte wide) encoding instead of the large (5-byte wide) one. - Rename art::DexRegisterMap::LocationKind as art::DexRegisterLocation::Kind, turn it into a strongly-typed enum based on a uint8_t, and extend it to support new kinds (kInStackLargeOffset and kConstantLargeValue). - Move art::DexRegisterEntry from compiler/optimizing/stack_map_stream.h to runtime/stack_map.h and rename it as art::DexRegisterLocation. - Adjust art::StackMapStream, art::CodeGenerator::RecordPcInfo, art::CheckReferenceMapVisitor::CheckOptimizedMethod, art::StackVisitor::GetVRegFromOptimizedCode, and art::StackVisitor::SetVRegFromOptimizedCode. - Implement unaligned memory accesses in art::MemoryRegion. - Use them to manipulate data in Dex register maps. - Adjust oatdump to support the new Dex register encoding. - Update compiler/optimizing/stack_map_test.cc.

* Create OatFileAssistant class for assisting with oat files.Richard Uhler2015-03-091-6/+0
| | | | | | | | | | | | | | | The oat file assistant is used for determining whether dex2oat or patchoat is needed, for running dex2oat or patchoat as needed to make an oat file up to date, and to load dex files associated with a given dex location.

* dex2oat: Pack likely-dirty objects together when generating the boot imageIgor Murashkin2014-11-201-1/+42
| | | | | | | | | | | | | | | | | | | | This introduces a new algorithm into image writer which "bins" objects by how likely they are to be dirtied at runtime. Objects in the same bin are placed contiguously in memory (i.e. into the same page). We try to tune the bin selection based on how clean or how dirty the object will likely be at runtime. As-is, this saves about 150KB per-process (private-dirty pages) and 700KB in zygote (shared-dirty). There is still about 800KB of objects that are clean but located in dirty pages, so with more analysis we can tune the bin selection and get even more memory savings.

* Reduce and speed-up class def searches.Ian Rogers2014-09-021-1/+1
| | | | | | | | | | | | | | | | | | | | Use the class linker for descriptor lookups from the compile driver so that dex caches are populated. Reduce the scope of functions for scanning class paths to just the class linker where they are performed. If we see more than a threshold number of find class def misses on a dex file lazily compute an index, so that future lookups are constant time (part of the collection code is taken from https://android-review.googlesource.com/#/c/103865/3). Note that we take a lazy approach so that we don't serialize on loading dex files, this avoids the reason the index was removed in 8b2c0b9abc3f520495f4387ea040132ba85cae69.

You should see stack frames down to main() Change-Id: I2d17e9aa0f6d42d374b5362a15ea35a2fce96302
* Runtime can now be set to require relocationAlex Light2014-07-221-1/+12
| | | | | | | | | | | | | | Add a pair of runtime flags -Xrelocate and -Xnorelocate that can force the runtime to require that all files that are run are relocated, to prevent attacks based on the known art base address. Add support for running patchoat on oat files compiled without an image. Change run-test to have new --prebuild and --relocate flags.

| * Disable adding main and non moving spaces to immune region in GSSMathieu Chartier2014-07-161-6/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Disabled adding the main and non moving space to the immune region. This will enable us to recycle bump pointer spaces for malloc space -> malloc space compaction as well as collector transitions. Also added logic for falling back to the non moving space, we may copy objects there. Refactored mod union table logic into MarkReachableObjects. No measurable performance benefit or regression.

* | Break apart header files.Ian Rogers2014-07-151-2/+1
|/ | | | | | | | Create libart-gtest for common runtime and compiler gtest routines. Rename CompilerCallbacksImpl that is quick compiler specific. Rename trace clock source constants to not use the overloaded profiler term. Change-Id: I4aac4bdc7e7850c68335f81e59a390133b54e933
* Improve performance of invokevirtual/invokeinterface with embedded imt/vtableMingyao Yang2014-07-111-0/+14
| | | | | | | | | Add an embedded version of imt/vtable into class object. Both tables start at fixed offset within class object so method/entry point can be loaded directly from class object for invokeinterface/invokevirtual. Bug: 8142917 Change-Id: I4240d58cfbe9250107c95c0708c036854c455968
* Add patchoat tool to Art.Alex Light2014-07-071-0/+29
| | | | | | | | | | | | | Add a new executable called patchoat to art. This tool takes already compiled images and oat files and changes their base address, acting as a cheap form of relocation. Add a --include-patch-information flag to dex2oat and code to add required patch information to oat files created with the quick compiler.

* ART: Rework Generic JNI, add ARM versionAndreas Gampe2014-07-011-0/+13
| | | | | | | Refactors and optimizes Generic JNI. This version uses TwoWordReturn to avoid writing to / loading from the bottom of the alloca. Change-Id: I3287007c976f79c9fd32d3b3a43f2d1371bf4cd3
* ART: Native support for multidexAndreas Gampe2014-06-251-0/+1
| | | | | | | | | | | | | | | | | | | | Native support for zip files with multiple classesX.dex. Works by explicitly looking for those files in ascending order. As these files have no file system representation for themselves, introduce synthetic dex locations: the name of the originating file plus a colon plus the name of the dex file, e.g., test.jar:classes2.dex. Opening a zip dex file will return all dex files in this way. This keeps the changes to dex2oat minimal. To hide multidex/synthetic names from the Java layer, let the handle of dalvik.system.DexFile refer to a vector of DexFile objects. When opening a location, test possible synthetic names and add them to the vector. Thus, the original multidex jar in the classpath will be associated with all embedded dex files.

* More advanced timing loggers.Mathieu Chartier2014-06-241-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The new timing loggers have lower overhead since they only push into a vector. The new format has two types, a start timing and a stop timing. You can thing of these as brackets associated with a timestamp. It uses these to construct various statistics when needed, such as: Total time, exclusive time, and nesting depth. Changed PrettyDuration to have a default of 3 digits after the decimal point.
