* Move mirror::ArtMethod to nativeMathieu Chartier2015-06-021-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Opt compiler: Implement parallel move resolver without using swap.Zheng Xu2015-04-171-0/+5
| | | | | | | | | | | | | | | | | | The algorithm of ParallelMoveResolverNoSwap() is almost the same with ParallelMoveResolverWithSwap(), except the way we resolve the circular dependency. NoSwap() uses additional scratch register to resolve the circular dependency. For example, (0->1) (1->2) (2->0) will be performed as (2->scratch) (1->2) (0->1) (scratch->0). On architectures without swap register support, NoSwap() can reduce the number of moves from 3x(N-1) to (N+1) when there is circular dependency with N moves. And also, NoSwap() algorithm does not depend on architecture register layout information, which means it can support register pairs on arm32 and X/W, D/S registers on arm64 without additional modification.

* ART: Introduce NO_RETURN, Mark DoLongJump noreturnAndreas Gampe2015-02-231-0/+3
| | | | | | | Add NO_RETURN macro that adds C++11 noreturn attribute. Mark DoLongJump methods as noreturn. Change-Id: Ifde4318e370493237050d4c1349285a0382df23f
* ART: Do not inline elf writer debug symbolsAndreas Gampe2014-12-151-0/+2
| | | | | | | | | Using Clang, this pushes the frame size of the caller across our limit. Thus forbid inlining. The function is only called once per compile, impact is insignificant. Bug: 18738594 Change-Id: I19c3f1168a5104ab508a8dbf9f2a8c035cb97e3c

* Remove -Wno-unused-parameter and -Wno-sign-promo from base cflags.Ian Rogers2014-11-031-1/+13
| | | | | | | | | | | 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
* C++11 related clean-up of DISALLOW_..Ian Rogers2014-10-221-10/+16
| | | | | | | | | | | | | | | | | | Move DISALLOW_COPY_AND_ASSIGN to delete functions. By no having declarations with no definitions this prompts better warning messages so deal with these by correcting the code. Add a DISALLOW_ALLOCATION and use for ValueObject and mirror::Object. Make X86 assembly operand types ValueObjects to fix compilation errors. Tidy the use of iostream and ostream. Avoid making cutils a dependency via mutex-inl.h for tests that link against libart. Push tracing dependencies into appropriate files and mutex.cc. x86 32-bit host symbols size is increased for libarttest, avoid copying this in run-test 115 by using symlinks and remove this test's higher than normal ulimit. Fix the RunningOnValgrind test in RosAllocSpace to not use GetHeap as it returns NULL when the heap is under construction by Runtime. Change-Id: Ia246f7ac0c11f73072b30d70566a196e9b78472b
* Make ART compile with GCC -O0 again.Ian Rogers2014-10-161-0/+5
| | | | | | | | | | | | | 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. Bug: 17993736 Change-Id: I5f4b49e88c3b02a79f9bee04f83395146ed7be23
* Switch to C++11 style [[noreturn]].Ian Rogers2014-10-101-1/+0
| | | | | | | | 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 Rogers2014-10-101-0/+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
* Enable -Wimplicit-fallthrough.Ian Rogers2014-10-091-0/+42
| | | | | | | | Falling through switch cases on a clang build must now annotate the fallthrough with the FALLTHROUGH_INTENDED macro. Bug: 17731372 Change-Id: I836451cd5f96b01d1ababdbf9eef677fe8fa8324
* Enable -Wunreachable-codeIan Rogers2014-09-301-0/+1
| | | | | | | | Caught bugs in DeoptimizeStackVisitor and assemble_x86 SIB encoding. Add UNREACHABLE macro to document code expected to be unreachable. Bug: 17731047 Change-Id: I2e363fe5b38a1246354d98be18c902a6031c0b9e
* Disable adding main and non moving spaces to immune region in GSSMathieu Chartier2014-07-161-0/+1
| | | | | | | | | | | | | | | | | | Disabled adding the main and non moving space to the immune region. This will enable us to recycle bump pointer spaces for malloc space -> malloc space compaction as well as collector transitions. Also added logic for falling back to the non moving space, we may copy objects there. Refactored mod union table logic into MarkReachableObjects. No measurable performance benefit or regression.

* Implement FINAL/OVERRIDE for clang.Ian Rogers2014-03-131-1/+1
| | | | | | | | | | Separate declaration from definition in certain places to work-around issues with clang. Remove bogus lock annotation at definition in compilers.cc that is already present at the declaration. Remove duplicate definition of ClassReference.

* Enable annotalysis on clang ART builds.Ian Rogers2014-03-061-40/+32
| | | | | | | | | | | Fix clang build errors aswell as restructure locking/mutex code for correct thread safety analysis support. Reorder make dependencies so that host builds build first as they should provide better compilation errors than target. Remove host's use of -fno-omit-frame-pointer as it has no value with correct use of CFI, which we should have. Change-Id: I72cea8da9a3757b1a0b3acb4081feccb7c6cef90
* Make allocations report usable size.Ian Rogers2014-02-261-0/+9
| | | | | | | | | | | | | | | Work-in-progress to allow arrays to fill usable size. Bug: 13028925. Use C++11's override keyword on GCC >= 2.7 to ensure that we override GC and allocator methods. Move initial mirror::Class set up into a Functor so that all allocated objects have non-zero sizes. Use this property to assert that all objects are never larger than their usable size. Other bits of GC related clean-up, missing initialization, missing use of const, hot methods in .cc files, "unimplemented" functions that fail at runtime in header files, reducing header file includes, move valgrind's space into its own files, reduce number of array allocation routines.

* Don't rely on gcc extensionsBernhard Rosenkränzer2013-12-121-0/+7
| | | | | | | | | | | | | | Make the code more compatible with different compilers. clang doesn't allow extra static qualifiers on template specializations, const qualifiers on function types, or inline attributes on lambda functions, and is more picky about casting away constness with reinterpret_cast. These modifications are compatible with both gcc and clang. Change-Id: I739b10df2780bec537827a13679fd2bcc2cc7188 Signed-off-by: Bernhard Rosenkränzer <Bernhard.Rosenkranzer@linaro.org>
* Support hardware divide instructionDave Allison2013-11-051-0/+4
| | | | | | | | | | | | | | | | | | | | | Bug: 11299025 Uses sdiv for division and a combo of sdiv, mul and sub for modulus. Only does this on processors that are capable of the sdiv instruction, as determined by the build system. Also provides a command line arg --instruction-set-features= to allow cross compilation. Makefile adds the --instruction-set-features= arg to build-time dex2oat runs and defaults it to something obtained from the target architecture. Provides a GetInstructionSetFeatures() function on CompilerDriver that can be queried for various features. The only feature supported right now is hasDivideInstruction(). Also adds a few more instructions to the ARM disassembler b/11535253 is an addition to this CL to be done later. Change-Id: Ia8aaf801fd94bc71e476902749cf20f74eba9f68

* Create separate Android.mk for main build targetsBrian Carlstrom2013-07-121-0/+201
The runtime, compiler, dex2oat, and oatdump now are in seperate trees to prevent dependency creep. They can now be individually built without rebuilding the rest of the art projects. dalvikvm and jdwpspy were already this way. Builds in the art directory should behave as before, building everything including tests. Change-Id: Ic6b1151e5ed0f823c3dd301afd2b13eb2d8feb81
