* Improve Thumb disassembler for LDR/STR/PUSH/POP/BKPT.Vladimir Marko2015-01-061-232/+222
| | | | | | | | | | | | | Disassemble 16-bit Thumb PUSH, POP, BKPT. Clean up 32-bit load/store to handle all cases (including previously unrecognized indexed load/store) in one place; this also fixes LDRSH erroneously disassembled as LDRSB. Recognize more UNDEFINED instructions and other minor cleanup. Change-Id: Ifdd177745b70e3f774cc0469deb81191b035f51b
* ARM: Combine multiply accumulate operations.Ningsheng Jian2014-12-111-1/+1
| | | | | | | Try to combine integer multiply and add(sub) into a MAC operation. For AArch64, also try to combine long type multiply and add(sub). Change-Id: Ic85812e941eb5a66abc355cab81a4dd16de1b66e
* ART: More warningsAndreas Gampe2014-11-041-44/+5
| | | | | | | Enable -Wno-conversion-null, -Wredundant-decls and -Wshadow in general, and -Wunused-but-set-parameter for GCC builds. Change-Id: I81bbdd762213444673c65d85edae594a523836e5
* C++11 related clean-up of DISALLOW_..Ian Rogers2014-10-221-1/+1
| | | | | | | | | | | | | | | | | | 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
* Tidy up logging.Ian Rogers2014-10-221-0/+1
| | | | | | | | | | | | | | | | | Move gVerboseMethods to CompilerOptions. Now "--verbose-methods=" option to dex2oat rather than runtime argument "-verbose-methods:". Move ToStr and Dumpable out of logging.h, move LogMessageData into logging.cc except for a forward declaration. Remove ConstDumpable as Dump methods are all const (and make this so if not currently true). Make LogSeverity an enum and improve compile time assertions and type checking. Remove log_severity.h that's only used in logging.h. With system headers gone from logging.h, go add to .cc files missing system header includes. Also, make operator new in ValueObject private for compile time instantiation checking. Change-Id: I3228f614500ccc9b14b49c72b9821c8b0db3d641
* Enable -Wimplicit-fallthrough.Ian Rogers2014-10-091-5/+6
| | | | | | | | Falling through switch cases on a clang build must now annotate the fallthrough with the FALLTHROUGH_INTENDED macro. Bug: 17731372 Change-Id: I836451cd5f96b01d1ababdbf9eef677fe8fa8324
* ART: Fix some -Wpedantic errorsAndreas Gampe2014-09-291-9/+9
| | | | | | | | | | | | | | | | 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
* Avoid printing absolute addresses in oatdumpBrian Carlstrom2014-09-161-4/+10
| | | | | | | | | | | | | | | | | - Added printing of OatClass offsets. - Added printing of OatMethod offsets. - Added bounds checks for code size size, code size, mapping table, gc map, vmap table. - Added sanity check of 100k for code size. - Added partial disassembly of questionable code. - Added --no-disassemble to disable disassembly. - Added --no-dump:vmap to disable vmap dumping. - Reordered OatMethod info to be in file order. Bug: 15567083 (cherry picked from commit 34fa79ece5b3a1940d412cd94dbdcc4225aae72f) Change-Id: I2c368f3b81af53b735149a866f3e491c9ac33fb8
* Implement array get and array put in optimizing.Nicolas Geoffray2014-07-281-8/+40
| | | | | | Also fix a couple of assembler/disassembler issues. Change-Id: I705c8572988c1a9c4df3172b304678529636d5f6
* Add some more instruction support to optimizing compiler.Dave Allison2014-06-241-15/+54
| | | | | | | | | | | | | | | This adds a few more DEX instructions to the optimizing compiler's builder (constants, moves, if_xx, etc). Also: * Changes the codegen for IF_XX instructions to use a condition rather than comparing a value against 0. * Fixes some instructions in the ARM disassembler. * Fixes PushList and PopList in the thumb2 assembler. * Switches the assembler for the optimizing compiler to thumb2 rather than ARM. Change-Id: Iaafcd02243ccc5b03a054ef7a15285b84c06740f

| | | | | | This reverts commit 754ddad084ccb610d0cf486f6131bdc69bae5bc6. Change-Id: Icd979adee1d8d781b40a5e75daf3719444cb72e8
* Use trampolines for calls to helpersDave Allison2014-04-041-5/+25
| | | | | | | | | | | | | | | | | | | | | | 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
* Disassemble Thumb2 shifts and more VFP instructions.Vladimir Marko2014-04-031-117/+192
| | | | | | | | | | | | | Disassemble Thumb2 instructions LSL, LSR, ASR, ROR and VFP instructions VABS, VADD, VSUB, VMOV, VMUL, VNMUL, VDIV. Clean up disassembly of VCMP, VCMPE, VNEG and VSQRT. These could have been erroneously used for other insns (VSQRT for VMOV was encountered) and one VSQRT branch was unreachable. Remove duplicate VMOV opcodes from compiler.

* Allow mixing of thread offsets between 32 and 64bit architectures.Ian Rogers2014-04-011-4/+4
| | | | | | | Begin a more full implementation x86-64 REX prefixes. Doesn't implement 64bit thread offset support for the JNI compiler. Change-Id: If9af2f08a1833c21ddb4b4077f9b03add1a05147

* ARM: Remove duplicated instructions; add vcvt, vmla, vmls disassembler.Zheng Xu2014-03-101-0/+86
| | | | | | | Remove kThumb2VcvtID in the assembler which was duplicated. Add vcvt, vmla, vmls in the disassembler. Change-Id: I14cc39375c922c9917274d8dcfcb515e888fdf26
* Object model changes to support 64bit.Ian Rogers2014-02-061-1/+3
| | | | | | | | | | | | | | | | | | | | | | | 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

* Support hardware divide instructionDave Allison2013-11-051-25/+207
| | | | | | | | | | | | | | | | | | | | | 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
