* Move mirror::ArtMethod to nativeMathieu Chartier2015-06-021-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Optimizing + quick tests are passing, devices boot. TODO: Test and fix bugs in mips64. Saves 16 bytes per most ArtMethod, 7.5MB reduction in system PSS. Some of the savings are from removal of virtual methods and direct methods object arrays. Bug: 19264997 (cherry picked from commit e401d146407d61eeb99f8d6176b2ac13c4df1e33) Change-Id: I622469a0cfa0e7082a2119f3d6a9491eb61e3f3d Fix some ArtMethod related bugs Added root visiting for runtime methods, not currently required since the GcRoots in these methods are null. Added missing GetInterfaceMethodIfProxy in GetMethodLine, fixes --trace run-tests 005, 044. Fixed optimizing compiler bug where we used a normal stack location instead of double on ARM64, this fixes the debuggable tests. TODO: Fix JDWP tests. Bug: 19264997 Change-Id: I7c55f69c61d1b45351fd0dc7185ffe5efad82bd3 ART: Fix casts for 64-bit pointers on 32-bit compiler. Bug: 19264997 Change-Id: Ief45cdd4bae5a43fc8bfdfa7cf744e2c57529457 Fix JDWP tests after ArtMethod change Fixes Throwable::GetStackDepth for exception event detection after internal stack trace representation change. Adds missing ArtMethod::GetInterfaceMethodIfProxy call in case of proxy method. Bug: 19264997 Change-Id: I363e293796848c3ec491c963813f62d868da44d2 Fix accidental IMT and root marking regression Was always using the conflict trampoline. Also included fix for regression in GC time caused by extra roots. Most of the regression was IMT. Fixed bug in DumpGcPerformanceInfo where we would get SIGABRT due to detached thread. EvaluateAndApplyChanges: From ~2500 -> ~1980 GC time: 8.2s -> 7.2s due to 1s less of MarkConcurrentRoots Bug: 19264997 Change-Id: I4333e80a8268c2ed1284f87f25b9f113d4f2c7e0 Fix bogus image test assert Previously we were comparing the size of the non moving space to size of the image file. Now we properly compare the size of the image space against the size of the image file. Bug: 19264997 Change-Id: I7359f1f73ae3df60c5147245935a24431c04808a [MIPS64] Fix art_quick_invoke_stub argument offsets. ArtMethod reference's size got bigger, so we need to move other args and leave enough space for ArtMethod* and 'this' pointer. This fixes mips64 boot. Bug: 19264997 Change-Id: I47198d5f39a4caab30b3b77479d5eedaad5006ab

* ART: Allow to compile interpret-only mips64 filesAndreas Gampe2015-01-151-0/+4
| | | | | | | | | | | | Include enough infrastructure to allow cross-compiling for mips64, interpret-only. This includes the instruction-set-features, frame size info and utils assembler. Also add a disassembler for oatdump, and support in patchoat. Note: the runtime cannot run mips64, yet. Change-Id: Id106581fa76b478984741c62a8a03be0f370d992
* ART: Swap-space in the compilerAndreas Gampe2014-12-221-0/+2
| | | | | | | | | | | Introduce a swap-space and corresponding allocator to transparently switch native allocations to memory backed by a file. Bug: 18596910 (cherry picked from commit 62746d8d9c4400e4764f162b22bfb1a32be287a9) Change-Id: I131448f3907115054a592af73db86d2b9257ea33
* Instruction set features for ARM64, MIPS and X86.Ian Rogers2014-11-131-4/+4
| | | | | | | | | | | | | 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
* ART: More warningsAndreas Gampe2014-11-041-5/+5
| | | | | | | Enable -Wno-conversion-null, -Wredundant-decls and -Wshadow in general, and -Wunused-but-set-parameter for GCC builds. Change-Id: I81bbdd762213444673c65d85edae594a523836e5
* Remove -Wno-unused-parameter and -Wno-sign-promo from base cflags.Ian Rogers2014-11-031-1/+1
| | | | | | | | | | | 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
* ART: optimizing compiler: initial support for ARM64.Alexandre Rames2014-10-231-0/+1
| | | | | | | | | | The ARM64 port uses VIXL for code generation, to which it defers work like label binding and branch resolving, register type coherency checking, and immediate values handling.

* Emit CFI for x86 & x86_64 JNI compiler.Tong Shen2014-08-051-0/+4
| | | | | | | | | | | Now for host-side x86 & x86_64 ART, we are able to get complete stacktrace with even mixed C/C++ & Java stack frames. Testing: 1. art/test/run-test --host --gdb [--64] --no-relocate 005 2. In gdb, run 'b art::Class_classForName' which is implementation of a Java native method, then 'r' 3. In gdb, run 'bt'. You should see stack frames down to main() Change-Id: I2d17e9aa0f6d42d374b5362a15ea35a2fce96302
* Thumb2 assembler for JNI compiler and optimizing compilerDave Allison2014-06-051-1/+14
| | | | | | | | | | | | | | | | | | | | This provides a programmatic assembler for the thumb2 instruction set for ARM. The interface is the same as the ARM assembler and the ARM assembler has been moved into Arm32Assembler. The assembler handles most 16 and 32 bit instructions and also allows relocations due to branch expansion. It will also rewrite cbz/cbnz instructions if they go out of range. It also changes the JNI compiler to use the thumb2 assembler as opposed to forcing it to use ARM32. The trampoline compiler still uses ARM due to the way it returns the address of its generated code. A trampoline in thumb2 is the same size as that in ARM anyway (8 bytes). Provides gtest for testing the thumb2 instruction output. This gtest only runs on the host as it uses arm-eabi-objdump to disassemble the generated code. On the target the output is not checked but the assembler will still be run to perform all its checks.

* Add Handle/HandleScope and delete SirtRef.Mathieu Chartier2014-05-131-7/+7
| | | | | | | | | | | | | | | | Delete SirtRef and replaced it with Handle. Handles are value types which wrap around StackReference*. Renamed StackIndirectReferenceTable to HandleScope. Added a scoped handle wrapper which wraps around an Object** and restores it in its destructor. Renamed Handle::get -> Get. Bug: 8473721 Change-Id: Idbfebd4f35af629f0f43931b7c5184b334822c7a
* Allow mixing of thread offsets between 32 and 64bit architectures.Ian Rogers2014-04-011-19/+28
| | | | | | | Begin a more full implementation x86-64 REX prefixes. Doesn't implement 64bit thread offset support for the JNI compiler. Change-Id: If9af2f08a1833c21ddb4b4077f9b03add1a05147

| * Add support for invoke-static in optimizing compiler.Nicolas Geoffray2014-03-311-0/+17
| | | | | | | | | | | | | | Support is limited to calls without parameters and returning void. For simplicity, we currently follow the Quick ABI. Change-Id: I54805161141b7eac5959f1cae0dc138dd0b2e8a5
* | x86_64: JNI compilerDmitry Petrochenko2014-03-281-1/+6
|/ | | | | | | | | | | Passed all tests from jni_compiler_test and art/test on host with jni_copiler. Incoming argument spill is enabled, entry_spills refactored. Now each entry spill contains data type size (4 or 8) and offset which should be used for spill. Assembler REX support implemented in opcodes used in JNI compiler. Please note, JNI compiler is not enabled by default yet (see compiler_driver.cc:1875).

* AArch64: Add arm64 runtime support.Stuart Monteith2014-03-191-0/+3
| | | | | | | | | Adds support for arm64 to ART. Assembler stubs are sufficient for down calls into interpreter. JNI compiler and generics are not finished. Basic Generic JNI functionality. Change-Id: I4a07c79d1e037b9f5746673480e32cf456867b82
* AArch64: Add ARM64 AssemblerSerban Constantinescu2014-03-051-3/+3
| | | | | | | | | This patch adds the ARM64 Assembler and ManagedRegister backend. The implementation of the Arm64Assembler class is based on VIXL (a programmatic A64 Assembler - see external/vixl ).

* | Fix clang to compile and run host tests.Ian Rogers2014-02-281-0/+2
|/ | | | | | | | | | | | | | Don't use the computed goto interpreter with clang 3.4 as it causes compilation to hang. Avoid inclusion of LLVM_(HOST|DEVICE)_BUILD_MK except for with portable as it sets clang incompatible cflags. Most fixes are self-evident, for the quick dex file method inliner the enums were being used with ostreams, so fix the enums and operator out python script to allow this. Note this change effects portable but this is untestable as portable was broken by ELF file and mc linker changes. Change-Id: Ia54348f6b1bd3f76d3b71c6e8c5f97626386b903
* Fix up TODO: c++0x, update cpplint.Mathieu Chartier2013-08-161-0/+1
| | | | | | | | | | | | Needed to update cpplint to handle const auto. Fixed a few cpplint errors that were being missed before. Replaced most of the TODO c++0x with ranged based loops. Loops which do not have a descriptive container name have a concrete type instead of auto. Change-Id: Id7cc0f27030f56057c544e94277300b3f298c9c5
* Move assembler out of runtime into compiler/utils.Ian Rogers2013-07-291-0/+459
Other directory layout bits of clean up. There is still work to separate quick and portable in some files (e.g. argument visitor, proxy..). Change-Id: If8fecffda8ba5c4c47a035f0c622c538c6b58351
