* New experimental GC stress modeMathieu Chartier2015-06-221-1/+5
| | | | | | | | | | | | | | | Tries to do a GC for every unique call stack (up to 16 frames). The goal is to catch moving GC bugs and lock violations without being rediculously slow. Some tests fail on 64 bits, 32 bit host doesn't work. N5 is booting. Added runtime -Xgc options: gcstress and nogcstress.

* Fix debuggable compiler flag detection for secondary dex filesSebastien Hertz2015-05-191-4/+0
| | | | | | | | | | | | | | | | | | Compiles secondary dex files like the primary dex file: if it has been compiled with the --debuggable flag, compile secondary dex files with the --debuggable flag too. Therefore, dex files loaded at runtime are compiled the same way as dex files compiled at install time on the classpath (excluding the boot image that is not compiled debuggable). Also adds debuggable key in the oat header and bump the oat version.

* ART: Streaming trace modeAndreas Gampe2015-04-151-12/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Refactor and improve GC root handlingMathieu Chartier2015-04-061-48/+48
| | | | | | | | | | | | | | | | | | | | | | Changed GcRoot to use compressed references. Changed root visiting to use virtual functions instead of function pointers. Changed root visting interface to be an array of roots instead of a single root at a time. Added buffered root marking helper to avoid dispatch overhead. Root marking seems a bit faster on EvaluateAndApplyChanges due to batch marking. Pause times unaffected. Mips64 is untested but might work, maybe.

| * | Use specific exception class to abort transactionSebastien Hertz2015-04-031-5/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We used to throw a java.lang.InternalError when aborting a transaction (when preinitializing image classes at compilation time). We now use dedicated class dalvik.system.TransactionAbortError that is only thrown by the compiler to abort a transaction. This class has constructors taking a java.lang.Throwable "cause" so we can wrap exceptions causing the transaction to abort (for instance class java.lang.ClassNotFoundException) and give more information about the cause of the transaction abort.

|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Main motivation is to remove all the functionality / field access on java side to ArtField. Also comes with some reflection speedups / slowdowns. Summary results: getDeclaredField/getField are slower mostly due to JNI overhead.

| | | | | | | | | | | | | | | | | | | | Use an actual PathClassLoader when compiling apps, instead of a side structure and cutout. This CL sets up a minimal object 'cluster' that recreates the Java side of a regular ClassLoader such that the Class-Linker will recognize it and use the internal native fast-path. This CL removes the now unnecessary compile-time-classpath and replaces it with a single 'compiling-the-boot-image' flag in the compiler callbacks. Note: This functionality is *only* intended for the compiler, as the objects have not been completely initialized. Bug: 19781184 Change-Id: I7f36af12dd7852d21281110a25c119e8c0669c1d

JIT options: -Xjit / -Xnojit -Xjitcodecachesize:N -Xjitthreshold:integervalue The JIT has a shared copy of a compiler driver which is accessed by worker threads to compile individual methods. Added JIT code cache and data cache, currently sized at 2 MB capacity by default. Most apps will only fill a small fraction of this cache however. Added support to the compiler for compiling interpreter quickened byte codes. Added test target ART_TEST_JIT=TRUE and --jit for run-test. TODO: Clean up code cache. Delete compiled methods after they are added to code cache. Add more optimizations related to runtime checks e.g. direct pointers for invokes. Add method recompilation. Move instrumentation to DexFile to improve performance and reduce memory usage. Bug: 17950037 Change-Id: Ifa5b2684a2d5059ec5a5210733900aafa3c51bca

* | ART: Allow the execution to stop if the compilation fails via an optionJean Christophe Beyler2015-02-231-1/+10
|/ | | | | | | | | | | | | | | | | | | | | The current implementation continues the execution of the application if dex2oat fails by relying on the interpreter. This patch adds a -Xno-dex-file-fallback option to stop the default behavior. This can be used two-fold. First, one can enforce that a runtime only starts with a boot image. A follow-up patch will ensure that dex2oat (for apps) and patchoat in general request that mode and close gracefully otherwise. Second, this can be used for testing and debugging purposes, as it ensures that compiler failures & aborts are not silently ignored. Add testing.
