* 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.

* Remove deprecated WITH_HOST_DALVIK.Ian Rogers2014-06-101-8/+6
| | | | | | | | | | | | | | | | | | | | | | | Bug: 13751317 Fix the Mac build: - disable x86 selector removal that causes OS/X 10.9 kernel panics, - madvise don't need does zero memory on the Mac, factor into MemMap routine, - switch to the elf.h in elfutils to avoid Linux kernel dependencies, - we can't rely on exclusive_owner_ being available from other pthread libraries so maintain our own when futexes aren't available (we can't rely on the OS/X 10.8 hack any more), - fix symbol naming in assembly code, - work around C library differences, - disable backtrace in DumpNativeStack to avoid a broken libbacktrace dependency, - disable main thread signal handling logic, - align the stack in stub_test, - use $(HOST_SHLIB_SUFFIX) rather than .so in host make file variables. Not all host tests are passing on the Mac with this change. dex2oat works as does running HelloWorld. Change-Id: I5a232aedfb2028524d49daa6397a8e60f3ee40d3

| * ART: Fixes an issue with REX prefix for instructions with no ModRM byteVladimir Kostyukov2014-04-171-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are instructions (such as push, pop, mov) in the x86 ISA that encode first operands in their opcodes (opcode + reg). In order to enable an extended 64bit registers (R9-R15) a special prefix REX.B should be emitted before such instructions. This patch fixes the issue when REX.R prefix was emitted before instructions with no MorRM byte. So, the REX-prefix was simply ignored by CPU for those instructions whose operands are encoded in their opcodes. This patch makes the jni_compiler_test passed with JNI compiler enabled for x86_64 target.

* 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

* Relaxed memory barriers for x86Razvan A Lupusoru2014-03-261-0/+6
| | | | | | | | | | X86 provides stronger memory guarantees and thus the memory barriers can be optimized. This patch ensures that all memory barriers for x86 are treated as scheduling barriers.

* Fix clang to compile and run host tests.Ian Rogers2014-02-281-4/+0
| | | | | | | | | | | | | | 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

| | | | | | | | | | | | | | | | | | | | | | | 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

This patch updates the x86 implementation so it does not call memcpy and instead generates loads and stores, favoring movement of 128-bit chunks.
