* Revert "Tidy gAborting."Nicolas Geoffray2014-12-091-8/+3
| | | | | | | | Creates infinite loop: b/18674776. This reverts commit 015b137efb434528173779bc3ec8d72494456254. Change-Id: I67fe310d2e95ee2ec37bec842be06fb1123b6f4e
* Tidy gAborting.Ian Rogers2014-12-041-3/+8
| | | | | | | Reduce scope to Runtime::Abort and short-cut recursive case earlier. gAborting remains global to avoid two fatal errors in thread and the verifier. Change-Id: Ibc893f891ffee9a763c65cde9507d99083d47b3f
* Instruction set features for ARM64, MIPS and X86.Ian Rogers2014-11-131-1/+1
| | | | | | | | | | | | | Also, refactor how feature strings are handled so they are additive or subtractive. Make MIPS have features for FPU 32-bit and MIPS v2. Use in the quick compiler rather than #ifdefs that wouldn't have worked in cross-compilation. Add SIMD features for x86/x86-64 proposed in: https://android-review.googlesource.com/#/c/112370/ Bug: 18056890 Change-Id: Ic88ff84a714926bd277beb74a430c5c7d5ed7666
* Remove -Wno-unused-parameter and -Wno-sign-promo from base cflags.Ian Rogers2014-11-031-4/+4
| | | | | | | | | | | Fix associated errors about unused paramenters and implict sign conversions. For sign conversion this was largely in the area of enums, so add ostream operators for the effected enums and fix tools/generate-operator-out.py. Tidy arena allocation code and arena allocated data types, rather than fixing new and delete operators. Remove dead code. Change-Id: I5b433e722d2f75baacfacae4d32aef4a828bfe1b

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Added more inlining, removed imt array allocation and replaced it with a handle scope. Removed some un-necessary handle scopes. Added logic to base interface method tables from the superclass so that we dont need to reconstruct for every interface (large win).

* [native bridge] Make sure we always unload the native bridgeCalin Juravle2014-10-231-4/+6
| | | | | | | | | libnativebridge may allocate some resources during loading and intialization and de-allocate them when unloading. This makes sure that we don't leak anything. Bug: 18097480 Change-Id: I901f2d3c2ab1efb2875388f99e8c5c111ce82d5a
* Make ART compile with GCC -O0 again.Ian Rogers2014-10-161-6/+0
| | | | | | | | | | | | | Tidy up InstructionSetFeatures so that it has a type hierarchy dependent on architecture. Add to instruction_set_test to warn when InstructionSetFeatures don't agree with ones from system properties, AT_HWCAP and /proc/cpuinfo. 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.

* Switch to C++11 style [[noreturn]].Ian Rogers2014-10-101-4/+1
| | | | | | | | Also remove old comment about calls to Abort getting merged. We have few LOG(FATAL)s so merging is less of an issue. Also, recompiling with O0 and similar will avoid the optimization and we expect that for GDB debugging. Change-Id: I840dc6f4b8511294be0e117c634ec15b745e7be5
* Fix 2 new sets of clang compiler warnings.Ian Rogers2014-10-101-1/+1
| | | | | | | | | | | 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%.

* 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

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Added a custom allocator that lets you pass in a special tag which specifices where the allocation came from. This is used when dumping. The performance overhead is low since each allocation only does a atomic add/sub for each allocation/free. The measurements are dumped to traces.txt during SIGQUIT.

Change the bump pointer space size to be as large as the heap capacity instead of 1/2 heap capacity like it used to be. For GSS, bump pointer spaces are set to 32MB currently. Changed GSS to have main space == non moving space since we don't need to copy from the main space. Fixes GC stress tests 074, 096. Fixed test 080 oom throw with -Xmx2m for GC stress test, this was broken since it was allocating a 4 MB array before starting the OOM process.
