| | | | | | | | | | | | | | | | | | | | | | 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.

| * Use specific exception class to abort transactionSebastien Hertz2015-04-031-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* ART: PathClassLoader for compilerAndreas Gampe2015-03-271-16/+0
| | | | | | | | | | | | | | | | | | | | 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.

* | ART: Allow the execution to stop if the compilation fails via an optionJean Christophe Beyler2015-02-231-0/+8
|/ | | | | | | | | | | | | | | | | | | | | 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.

* Fix transaction abortingSebastien Hertz2015-02-051-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During compilation, a java.lang.InternalError is used to indicate that class initialization failed and the enclosing transaction should be aborted and the changes rolled back. However there is nothing preventing the code executed from a class initializer from catching that exception (like catching Throwable and ignore it). Therefore we may return from the class initializer with no pending exception, even if the transaction was aborted, and not rollback the changes properly. To fix this, we now rely on the new Transaction::aborted_ field to know whether a transaction aborted. When returning from the class initializer without pending exception, we now check wether we aborted the enclosing transaction. If that's the case, we set the status of the class to kStatusError and throw a new java.lang.InternalError with the original abort message. This CL also contains some cleanup: - Renames Transaction::Abort to Transaction::Rollback which is less ambiguous and more reflect what is done. - Moves the code throwing the java.lang.InternalError exception into the Transaction::ThrowInternalError method so we do not duplicate code. Now we may abort transaction more than once (because we may have caught the java.lang.InternalError then execute code causing new transaction abort), we only keep the first abort message to throw the exception. - Updates transaction_test with more cases and more checks. - Bumps oat version to force recompilation with this fix.

| | | | | | | | | | | Fix issues that are flagged by -Wfloat-equal and -Wmissing-noreturn. In the case of -Wfloat-equal the current cases in regular code are deliberate, so the change is to silence the warning. For gtest code the appropriate fix is to switch from EXPECT_EQ to EXPECT_(FLOAT|DOUBLE)_EQ. The -Wmissing-noreturn warning isn't enabled due to a missing noreturn in gtest. This issue has been reported to gtest. Change-Id: Id84c70c21c542716c9ee0c41492e8ff8788c4ef8

* Fix broken runtime SetStatsEnabled logicMathieu Chartier2014-09-261-1/+2
| | | | | | | | | | | | | | | Previously, Runtime::SetStatsEnabled wouldn't take stats_enabled_ into account when deciding whether or not to increment / decrement teh stats enabled counter. This resulted in counter underflows and other errors which caused some CTS tests to fail. Also added some locking to prevent race conditions.

* Compile time performance improvements focusing on interpret-only.Ian Rogers2014-09-121-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Reduce virtual method dispatch in the method verifier and make more code inline-able. Add a StringPiece with const char* equality operator to avoid redundant StringPieces and strlens. Remove back link from register line to verifier and pass as argument to reduce size of RegisterLine. Remove instruction length from instruction flags and compute from the instruction, again to reduce size. Add suspend checks to resolve and verify to allow for more easy monitor inflation and reduce contention on Locks::thread_list_suspend_thread_lock_. Change ThrowEarlierClassFailure to throw pre-allocated exception. Avoid calls to Thread::Current() by passing self. Template specialize IsValidClassName. Make ANR reporting with SIGQUIT run using checkpoints rather than suspending all threads. This makes the stack/lock analysis less lock error prone. Extra Barrier assertions and condition variable time out is now returned as a boolean both from Barrier and ConditionVariable::Wait. 2 threaded host x86-64 interpret-only numbers from 341 samples: Before change: Avg 176.137ms 99% CI 3.468ms to 1060.770ms After change: Avg 139.163% 99% CI 3.027ms to 838.257ms Reduction in average compile time after change is 20.9%. Slow-down without change is 26.5%. Bug: 17471626 - Fix bug where RegTypeCache::JavaLangObject/String/Class/Throwable could return unresolved type when class loading is disabled.

* ART: Fix things for valgrindAndreas Gampe2014-09-101-12/+1
| | | | | | | | | | | | | | | | | | | | | | Wire up valgrind gtests. Add valgrind-test-art-host, currently only depending on valgrind-test-art-host-gtest32. Fix an Alloc setting to allow running valgrind. Refactor the fault handler to manage (and correctly release) the handlers. Fix minor failure-case leaks exposed by tests. Failing tests: The optimizing compiler is leaking non-arena-ed structures (e.g., assembler buffers), as code generators are not destroyed. The solution has been moved to a follow-up CL. Note: All 64b tests are failing as we cannot allocate a heap. Change-Id: I7f854cfd098d9f68107ce492363e7dba9a82b9fa
