* Move mirror::ArtMethod to nativeMathieu Chartier2015-06-021-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: Clean up arm64 kNumberOfXRegisters usage.Vladimir Marko2015-05-261-1/+1
| | | | | | | | | | | | | | | | | | | | | 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.

* Don't use CanHoldArm in the code generator.Nicolas Geoffray2014-11-281-30/+0
| | | | | | | | CanHoldArm was ARM32 specific. Instead use a virtual Assembler::ShifterOperandCanHold that both thumb2 and arm32 implement. Change-Id: I33794a93caf02ee5d78d32a8471d9fd6fe4f0a00

* | ARM: Use hardfp calling convention between java to java call.Zheng Xu2014-10-241-2/+16
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | This patch default to use hardfp calling convention. Softfp can be enabled by setting kArm32QuickCodeUseSoftFloat to true. We get about -1 ~ +5% performance improvement with different benchmark tests. Hopefully, we should be able to get more performance by address the left TODOs, as some part of the code takes the original assumption which is not optimal. DONE: 1. Interpreter to quick code 2. Quick code to interpreter 3. Transition assembly and callee-saves 4. Trampoline(generic jni, resolution, invoke with access check and etc.) 5. Pass fp arg reg following aapcs(gpr and stack do not follow aapcs) 6. Quick helper assembly routines to handle ABI differences 7. Quick code method entry 8. Quick code method invocation 9. JNI compiler TODO: 10. Rework ArgMap, FlushIn, GenDalvikArgs and affected common code. 11. Rework CallRuntimeHelperXXX(). Change-Id: I9965d8a007f4829f2560b63bcbbde271bdcf6ec2

* ART: Fix some -Wpedantic errorsAndreas Gampe2014-09-291-8/+8
| | | | | | | | | | | | | | | | Remove extra semicolons. Dollar signs in C++ identifiers are an extension. Named variadic macros are an extension. Binary literals are a C++14 feature. Enum re-declarations are not allowed. Overflow. Change-Id: I7d16b2217b2ef2959ca69de84eaecc754517714a

* Support additional instructions in ARM and thumb assemblersDave Allison2014-06-261-67/+89
| | | | | | | | | | | | | This adds the following support for the ARM and thumb assemblers: 1. Shifting by a register. 2. LDR/STR with a register offset, possibly shifted. 3. LDR(literal). 4. STR PC relative. Also adds tests for them in the thumb assembler gtest. Change-Id: Ie467e3c1d06b699cacbdef3482ed9a92e4f1809b
* Thumb2 assembler for JNI compiler and optimizing compilerDave Allison2014-06-051-1310/+290
| | | | | | | | | | | | | | | | | | | | 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 Chartier2014-05-131-16/+16
| | | | | | | | | | | | | | | | 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

| | | | | | Add REX support for x86-64 operands. Change-Id: I093ae26fb8c111d54b8c72166f054984564c04c6
* Allow mixing of thread offsets between 32 and 64bit architectures.Ian Rogers2014-04-011-11/+11
| | | | | | | Begin a more full implementation x86-64 REX prefixes. Doesn't implement 64bit thread offset support for the JNI compiler. Change-Id: If9af2f08a1833c21ddb4b4077f9b03add1a05147
* x86_64: JNI compilerDmitry Petrochenko2014-03-281-1/+1
| | | | | | | | | | | 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).

* Entry point clean up.Ian Rogers2013-08-121-5/+5
| | | | | | | | | | | | | | | | | | Create set of entry points needed for image methods to avoid fix-up at load time: - interpreter - bridge to interpreter, bridge to compiled code - jni - dlsym lookup - quick - resolution and bridge to interpreter - portable - resolution and bridge to interpreter Fix JNI work around to use JNI work around argument rewriting code that'd been accidentally disabled. Remove abstact method error stub, use interpreter bridge instead. Consolidate trampoline (previously stub) generation in generic helper. Simplify trampolines to jump directly into assembly code, keeps stack crawlable. Dex: replace use of int with ThreadOffset for values that are thread offsets. Tidy entry point routines between interpreter, jni, quick and portable. Change-Id: I52a7c2bbb1b7e0ff8a3c3100b774212309d0828e (cherry picked from commit 848871b4d8481229c32e0d048a9856e5a9a17ef9)
