| * Disable parallel GC by defaultMathieu Chartier2015-04-151-2/+2
| | | | | | | | | | | | | | | | Not using parallel GC seems to reduce avg pauses by ~0.1s on EvaluateAndApplyChanges. Avoiding creating the thread pool should help app launch slightly and reduce memory ussage. Change-Id: Iebec2a17701c76e4145b41d7c0b4f6dd17806efa
* | ART: Streaming trace modeAndreas Gampe2015-04-151-0/+2
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

The proposed JIT is a method JIT which works by utilizing interpreter instrumentation to request compilation of hot methods async during runtime. 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 Beyler2015-02-231-0/+4
|/ | | | | | | | | | | | | | | | | | | | | 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.

* Implement a simple count based boot marker.Narayan Kamath2015-02-211-0/+3
| | | | | | | | | | | | | We write the number of failed boots to the marker and only prune the dalvik cache if the number of consecutive failed boots is higher than a predefined threshold. Note that the code is forgiving of errors related to boot markers; we continue the boot process even if we're unable to create / write or flush the boot marker. bug: 19360096 Change-Id: Ia17c3b783318ddf43c9199d0f7f09c54a4176667

| | | | | | | | | | | | | Refactor the RuntimeOptions to be a type-safe map (VariantMap, see runtime_options.h) and the ParsedOptions to delegate the parsing to CmdlineParser (see cmdline/cmdline_parser.h). This is the start of a command line parsing refactor, and may include more in the future (dex2oat, patchoat, etc).

* Follow up on CL 122665.Hiroshi Yamauchi2015-01-131-0/+6
| | | | | | | | | | | | | | | | | | We now do the two-step memory protection strategy (first protect the from space with PROT_READ and later protect it with PROT_NONE) only if the from space is a rosalloc space (excluding the more common bump pointer space case). This strengthens the GC verification for the bump pointer space case as we avoid the case where mutators run while the from space is PROT_READ rather than PROT_NONE. Add a command line flag to override the minimum interval for the hspace compaction for OOM and set it to zero in the gcstress/gcverify run-tests to run the hspace compaction more frequently in tests. Fix some comments. Bug: 18960494 Change-Id: I518b011e026f578e53c4ec269cfb82865b0fae68
* Remove back-door bootclasspath option from RuntimeRichard Uhler2015-01-081-4/+23
| | | | | | | | | | | | | | | | | The 'bootclasspath' option allowed users of the Runtime to load their own boot class path DexFiles and pass them directly to the Runtime as an option. This obscures the fact that the Runtime must take ownership of the boot class path DexFiles. This change removes the use of the bootclasspath option by dex2oat and the common runtime tests. For dex2oat, we use the existing -Xbootclasspath option instead, and introduce a new -Xbootclasspath-locations option to override the dex locations for the loaded boot class path dex files. For the common runtime tests, we simply use -Xbootclasspath. Bug: 18809837 Change-Id: Idfcd4885390bf0f3dc350993756dd337220def73

Remove ConstDumpable as Dump methods are all const (and make this so if not currently true). Make LogSeverity an enum and improve compile time assertions and type checking. Remove log_severity.h that's only used in logging.h. With system headers gone from logging.h, go add to .cc files missing system header includes.

Clean-up class linker entry point logic to not return entry points but to test whether the passed code is the particular entrypoint. This works around image trampolines that replicate entrypoints.
