2015-10-15Use ATTRIBUTE_UNUSED more. Roland Levillain
Use it in lieu of UNUSED(), which had some incorrect uses. Change-Id: If247dce58b72056f6eea84968e7196f0b5bef4da
2015-10-06MIPS: Assemblers changes needed for optimizing compiler Goran Jakovljevic
Also add assembler tests for MIPS32. Change-Id: I3ab1fba7f3b06eb3b5058861946d675494a30775
2015-09-17ART: Refactor intrinsics slow-paths Andreas Gampe
Refactor slow paths so that there is a default implementation for common cases (only arm64 with vixl is special). Write a generic intrinsic slow-path that can be reused for the specific architectures. Move helper functions into CodeGenerator so that they are accessible. Change-Id: Ibd788dce432601c6a9f7e6f13eab31f28dcb8550
2015-08-26X86: Assembler support for near labels Mark Mendell
The optimizing compiler uses 32 bit relative jumps for all forward jumps, just in case the offset is too large to fit in one byte. Some of the generated code knows that the jumps will in fact fit. Add a 'NearLabel' class to the x86 and x86_64 assemblers. This will be used to generate known short forward branches. Add jecxz/jrcxz instructions, which only handle a short offset. They will be used for intrinsics. Add tests for the new instructions and NearLabel. Change-Id: I11177f36394d35d63b32364b0e6289ee6d97de46 Signed-off-by: Mark Mendell <mark.p.mendell@intel.com>
2015-07-01Implement heap poisoning in ART's Optimizing compiler. Roland Levillain
- Instrument ARM, ARM64, x86 and x86-64 code generators. - Note: To turn heap poisoning on in Optimizing, set the environment variable `ART_HEAP_POISONING' to "true" before compiling ART. Bug: 12687968 Change-Id: Ib3120b38cf805a8a50207a314b9ccc90c8d93740
2015-06-22Opt compiler: Add disassembly to the '.cfg' output. Alexandre Rames
This is automatically added to the '.cfg' output when using the usual `--dump-cfg` option. Change-Id: I864bfc3a8299c042e72e451cc7730ad8271e4deb
2015-06-17Revert "Revert "ART: Implement literal pool for arm, fix branch fixup."" Vladimir Marko
This reverts commit fbeb4aede0ddc5b1e6a5a3a40cc6266fe8518c98. Adjust block label positions. Bad catch block labels were the reason for the revert. Change-Id: Ia6950d639d46b9da6b07f3ade63ab46d03d63310
2015-06-16Revert "ART: Implement literal pool for arm, fix branch fixup." Vladimir Marko
This reverts commit f38caa68cce551fb153dff37d01db518e58ed00f. Change-Id: Id88b82cc949d288cfcdb3c401b96f884b777fc40 Reason: broke the tests.

2015-05-29Move mirror::ArtMethod to native Mathieu Chartier
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 Change-Id: I622469a0cfa0e7082a2119f3d6a9491eb61e3f3d
2015-04-22Replace NULL with nullptr Mathieu Chartier
Also fixed some lines that were too long, and a few other minor details. Change-Id: I6efba5fb6e03eb5d0a300fddb2a75bf8e2f175cb
2015-04-08Implement CFI for JNI. David Srbecky
CFI is necessary for stack unwinding in gdb, lldb, and libunwind. Change-Id: I37eb7973f99a6975034cf0e699e138c3a9aba10f
2015-04-07Remove the old CFI infrastructure. David Srbecky
Change-Id: I12a17a8a1c39ffccaa499c328ebac36e4d74dc4e
2015-01-15ART: Allow to compile interpret-only mips64 files Andreas Gampe
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
2014-12-22ART: Swap-space in the compiler Andreas Gampe
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
2014-11-13Instruction set features for ARM64, MIPS and X86. Ian Rogers
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
2014-11-04ART: More warnings Andreas Gampe
Enable -Wno-conversion-null, -Wredundant-decls and -Wshadow in general, and -Wunused-but-set-parameter for GCC builds. Change-Id: I81bbdd762213444673c65d85edae594a523836e5
2014-11-03Remove -Wno-unused-parameter and -Wno-sign-promo from base cflags. Ian Rogers
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
2014-10-23ART: optimizing compiler: initial support for ARM64. Alexandre Rames
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.

2014-08-05Emit CFI for x86 & x86_64 JNI compiler. Tong Shen
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
2014-06-05Thumb2 assembler for JNI compiler and optimizing compiler Dave Allison
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.

2014-05-13Add Handle/HandleScope and delete SirtRef. Mathieu Chartier
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
2014-04-01Allow mixing of thread offsets between 32 and 64bit architectures. Ian Rogers
Begin a more full implementation x86-64 REX prefixes. Doesn't implement 64bit thread offset support for the JNI compiler. Change-Id: If9af2f08a1833c21ddb4b4077f9b03add1a05147
2014-03-31Merge "Add support for invoke-static in optimizing compiler." Nicolas Geoffray
2014-03-31Add support for invoke-static in optimizing compiler. Nicolas Geoffray
Support is limited to calls without parameters and returning void. For simplicity, we currently follow the Quick ABI. Change-Id: I54805161141b7eac5959f1cae0dc138dd0b2e8a5
2014-03-28x86_64: JNI compiler Dmitry Petrochenko
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).

2014-03-19AArch64: Add arm64 runtime support. Stuart Monteith
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
2014-03-05AArch64: Add ARM64 Assembler Serban Constantinescu
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 ).

2014-02-28Fix clang to compile and run host tests. Ian Rogers
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
2013-08-16Fix up TODO: c++0x, update cpplint. Mathieu Chartier
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
2013-07-29Move assembler out of runtime into compiler/utils. Ian Rogers
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
