* Add JITMathieu Chartier2015-02-231-15/+60
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently disabled by default unless -Xjit is passed in. The proposed JIT is a method JIT which works by utilizing interpreter instrumentation to request compilation of hot methods async during runtime. JIT options: -Xjit / -Xnojit -Xjitcodecachesize:N -Xjitthreshold:integervalue The JIT has a shared copy of a compiler driver which is accessed by worker threads to compile individual methods. Added JIT code cache and data cache, currently sized at 2 MB capacity by default. Most apps will only fill a small fraction of this cache however. Added support to the compiler for compiling interpreter quickened byte codes. Added test target ART_TEST_JIT=TRUE and --jit for run-test. TODO: Clean up code cache. Delete compiled methods after they are added to code cache. Add more optimizations related to runtime checks e.g. direct pointers for invokes. Add method recompilation. Move instrumentation to DexFile to improve performance and reduce memory usage. Bug: 17950037 Change-Id: Ifa5b2684a2d5059ec5a5210733900aafa3c51bca
* ART: Allow to compile interpret-only mips64 filesAndreas Gampe2015-01-151-0/+2
| | | | | | | | | | | | 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

* Ensure stack maps are 4 byte aligned.Nicolas Geoffray2014-12-091-2/+1
| | | | | | | | | | | | With the recent move to gcc 4.9, we are hitting alignment SIGBUS on ARM. The reason is that gcc will optimize two consecutive 32bits loads into one 64bits load, and the instruction (ldrd) will fail if the data is not aligned. Also removed the emission of mapping table when a method is optimized. The information can be found in the StackMap itself. Change-Id: Icf79406c18a3f4db3c05d52fc2c0dd2e35bf0f8f
* Implement method calls using relative BL on ARM.Vladimir Marko2014-09-251-6/+14
| | | | | | | | | | Store the linker patches with each CompiledMethod instead of keeping them in CompilerDriver. Reorganize oat file creation to apply the patches as we're writing the method code. Add framework for platform-specific relative call patches in the OatWriter. Implement relative call patches for ARM. Change-Id: Ie2effb3d92b61ac8f356140eba09dc37d62290f8
* Runtime support for the new stack maps for the opt compiler.Nicolas Geoffray2014-09-081-0/+19
| | | | | | | Now most of the methods supported by the compiler can be optimized, instead of using the baseline. Change-Id: I80ab36a34913fa4e7dd576c7bf55af63594dc1fa
* ART source line debug info in OAT filesYevgeny Rouban2014-08-151-11/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | OAT files have source line information enough for ART runtime needs like jump to/from interpreter and thread suspension. But this information is not enough for finer grained source level debugging and low-level profiling (VTune or perf). This patch adds to OAT files two additional sections: .debug_line - DWARF formatted Elf32 section with detailed source line information (mapping from native PC to Java source lines). In addition to the debugging symbols added using the dex2oat option --include-debug-symbols, the source line information is added to the section .debug_line. The source line info can be read by many Elf reading tools like objdump, readelf, dwarfdump, gdb, perf, VTune, ... gdb can use this debug line information in x86. In 64-bit mode the information can be used if the oat file is mapped in the lower address space (address has higher 32 bits zeroed). Relocation works. Testing: 1. art/test/run-test --host --gdb [--64] 001-HelloWorld 2. in gdb: break Main.java:19 3. in gdb: break Runtime.java:111 4. in gdb: run - stops at void java.lang.Runtime.<init>() 5. in gdb: backtrace - shows call stack down to main() 6. in gdb: continue - stops at void Main.main() (only in 32-bit mode) 7. in gdb: backtrace - shows call stack down to main() 8. objdump -W <oat-file> - addresses are from VMA range of .text section reported by objdump -h <file> 9. dwarfdump -ka <oat-file> - no errors expected Size of aosp-x86-eng boot.oat increased by 11% from 80.5Mb to 89.2Mb with two sections added .debug_line (7.2Mb) and .rel.debug (1.5Mb).

* Emit CFI for x86 & x86_64 JNI compiler.Tong Shen2014-08-051-2/+3
| | | | | | | | | | | 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
* Move trampolines to thumb2 instead of ARMDave Allison2014-06-231-2/+6
| | | | | | | | | Currently the entrypoint trampolines are compiled using the ARM32 assembler. This changes that to use the thumb2 assembler for consistency with the other compiled code. Bug: 15455279 Change-Id: I6bacdf359e2ae4c0967fb5cd9dc694af11f802ec
* Give Compiler a back reference to the driver.Ian Rogers2014-05-061-21/+21
| | | | | | | | | | The compiler driver is a single object delegating work to the compiler, rather than passing it through to every Compiler call make it a member of Compiler so that it maybe queried. This simplifies the Compiler API and makes the relationship to CompilerDriver more explicit. Remove reference arguments that contravene code style.

* Use trampolines for calls to helpersDave Allison2014-04-041-7/+10
| | | | | | | | | | | | | | | | | | | | | | This is an ARM specific optimization to the compiler that uses trampoline islands to make calls to runtime helper functions. The intention is to reduce the size of the generated code (by 2 bytes per call) without affecting performance. By default this is on when generating an OAT file. It is off when compiling to memory. To switch this off in dex2oat, use the command line option: --no-helper-trampolines Enhances disassembler to print the trampoline entry on the BL instruction like this: 0xb6a850c0: f7ffff9e bl -196 (0xb6a85000) ; pTestSuspend Bug: 12607709 Change-Id: I9202bdb7cf21252ad807bd48701f1f6ce8e3d0fe
* x86_64: JNI compilerDmitry Petrochenko2014-03-281-0/+2
| | | | | | | | | | | 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).

* Tell GDB about Quick ART generated codeMark Mendell2014-03-021-6/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is actually a lot of work. To do this, we need: .debug_info .debug_abbrev .debug_frame .debug_str These are generated into the OAT file by OatWriter and ElfWriterQuick. Since the Quick ART runtime doesn't use dlopen to load the OAT files, GDB can't find this information. Use the alternate GDB JIT interface, which can be invoked at runtime. To use this interface, an ELF image needs to be built in memory. Read the information from the OAT file, fixup the addresses to point to the real locations, add a symbol table to hold the .text symbol, and then let GDB know about the information, which will be read from the runtime address space. This is quite primitive now, and could be cleaned up considerably. It probably needs symbol table entries for the methods, and descriptions of parameters and return types. Currently only supported for X86. This defaults to enabled for debug builds. Added dexoat --gen-gdb-info and --no-gen-gdb-info flags to override.

* Object model changes to support 64bit.Ian Rogers2014-02-061-12/+41
| | | | | | | | | | | | | | | | | | | | | | | Modify mirror objects so that references between them use an ObjectReference value type rather than an Object* so that functionality to compress larger references can be captured in the ObjectRefererence implementation. ObjectReferences are 32bit and all other aspects of object layout remain as they are currently. Expand fields in objects holding pointers so they can hold 64bit pointers. Its expected the size of these will come down by improving where we hold compiler meta-data. Stub out x86_64 architecture specific runtime implementation. Modify OutputStream so that reads and writes are of unsigned quantities. Make the use of portable or quick code more explicit. Templatize AtomicInteger to support more than just int32_t as a type. Add missing, and fix issues relating to, missing annotalysis information on the mutator lock. Refactor and share implementations for array copy between System and uses elsewhere in the runtime. Fix numerous 64bit build issues. Change-Id: I1a5694c251a42c9eff71084dfdd4b51fff716822
* Multi threaded hashed deduplication during compilation.Mathieu Chartier2013-09-031-0/+170
Moved deduplication to be in the compiler driver instead of oat writer. This enables deduplication to be performed on multiple threads. Also added a hash function to avoid excessive comparison of byte arrays.
