* New experimental GC stress modeMathieu Chartier2015-06-221-0/+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. Bug: 21664466 (cherry picked from commit 310008008c90fea246efd00cb99ee7ded97c5209) Change-Id: Icb8e420f2048e8ee83bcca7937563166a2638f5c
* ART: Clean up arm64 kNumberOfXRegisters usage.Vladimir Marko2015-05-263-14/+13
| | | | | | | | | | | | | | | | | | | | | 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: Enable Clang's -WdeprecatedAndreas Gampe2015-04-061-0/+1
| | | | | | | | | Replace throw() with noexcept. Add default copy constructors and copy assignment constructors for cases with destructors, as the implicit definition is deprecated. Change-Id: Ice306a3f510b072b00bec4d4360f7c8055135c9d
* Create OatFileAssistant class for assisting with oat files.Richard Uhler2015-03-092-0/+9
| | | | | | | | | | | | | | | 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. The introduction of the OatFileAssistant class is meant to clean up and consolidate code related to the management of oat files that was duplicated and spread across dalvik_system_DexFile.cc and class_linker.cc.

| * ART: Fix "unused parameters"Andreas Gampe2015-02-245-14/+14
| | | | | | | | | | | | | | | | GCC 4.8 decides that parameters for functions implemented with "= default" are unused. This currently only impacts x86, but remove the parameter names anyways. Change-Id: I01865faa81af68c4c0e0b1cb1fb19e88ef548769

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/+1
|/ | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | Allocates JDWP::JdwpOptions on the heap and copies parsed options to avoid the need to include jdwp/jdwp.h into runtime.h file. Also does some minor cleanup and removes the old JDWP options parsing code that became dead code after we move it to the new command-line parser.

| | | | | | | | | | | | | 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).
