Revert "Revert "Refactor HGraphBuilder and SsaBuilder to remove HLocals"" This patch merges the instruction-building phases from HGraphBuilder and SsaBuilder into a single HInstructionBuilder class. As a result, it is not necessary to generate HLocal, HLoadLocal and HStoreLocal instructions any more, as the builder produces SSA form directly. Saves 5-15% of arena-allocated memory (see bug for more data): GMS 20.46MB => 19.26MB (-5.86%) Maps 24.12MB => 21.47MB (-10.98%) YouTube 28.60MB => 26.01MB (-9.05%) This CL fixed an issue with parsing quickened instructions.

Build dominator tree before generating HInstructions Second CL in the series of merging HGraphBuilder and SsaBuilder. This patch refactors the builders so that dominator tree can be built before any HInstructions are generated. This puts the SsaBuilder removal of HLoadLocals/HStoreLocals straight after HGraphBuilder's HInstruction generation phase. Next CL will therefore be able to merge them. This patch also adds util classes for iterating bytecode and switch tables which allowed to simplify the code. Bug: 27894376 Change-Id: Ic425d298b2e6e7980481ed697230b1a0b7904526

Optimizing: Improve const-string code generation. For strings in the boot image, use either direct pointers or pc-relative addresses. For other strings, use PC-relative access to the dex cache arrays for AOT and direct address of the string's dex cache slot for JIT.

ART: Implement HSelect This patch adds a new HIR instruction to Optimizing. HSelect returns one of two inputs based on the outcome of a condition. This is only initial implementation which: - defines the new instruction, - repurposes BooleanSimplifier to emit it, - extends InstructionSimplifier to statically resolve it, - updates existing code and tests accordingly. Code generators currently emit fallback if/then/else code and will be updated in follow-up CLs to use platform-specific conditional moves when possible.

Perform profile file analysis in dex2oat Dex2oat can accept now multiple profile files to drive a profile based compilation. --profile-file and --reference-profile-file speficy a pair of profile files which will be evaluated for significant differences before starting the compilation. If the difference is insignificant (according to some internal metric) the compilation is skipped and a message is logged. Multiple pairs of --profile-file and --reference-profile-file can be specified. This effectively enables multi user support since profiles for different users will be kept separately. --reference-profile-file can be left out, case in which the decision is solely based on --profile-file. If both flags are present, then their repetition should form unique pairs. If the compilation is performed and --reference-profile-file is given then its data is merged with the data from the corresponding --profile- file and saved back to the file. If no profile flags are given, dex2oat proceeds as before and compiles the dex files unconditionally. As part of this change - merge ProfileCompilationInfo and OfflineProfilingInfo under the same object. There was no use to keep them separate anymore. - SaveProfilingInfo now merges the data with what was in the file before instead of overwriting it.

ART: Refactor SsaBuilder for more precise typing info This patch refactors the SsaBuilder to do the following: 1) All phis are constructed live and marked dead if not used or proved to be conflicting. 2) Primitive type propagation, now not a separate pass, identifies conflicting types and marks corresponding phis dead. 3) When compiling --debuggable, DeadPhiHandling used to revive phis which had only environmental uses but did not attempt to resolve conflicts. This pass was removed as obsolete and is now superseded by primitive type propagation (identifying conflicting phis) and SsaDeadPhiEliminiation (keeping phis live if debuggable + env use). 4) Resolving conflicts requires correct primitive type information on all instructions. This was not the case for ArrayGet instructions which can have ambiguous types in the bytecode. To this end, SsaBuilder now runs reference type propagation and types ArrayGets from the type of the input array. 5) With RTP being run inside the SsaBuilder, it is not necessary to run it as a separate optimization pass. Optimizations can now assume that all instructions of type kPrimNot have reference type info after SsaBuilder (with the exception of NullConstant). 6) Graph now contains a reference type to be assigned to NullConstant. All reference type instructions therefore have RTI, as now enforced by the SsaChecker. Bug: 24252151 Bug: 24252100 Bug: 22538329 Bug: 25786318 Change-Id: I7a3aee1ff66c82d64b4846611c547af17e91d260

Add support for LZ4 compressed image files Added dex2oat option --image-format=(store|lz4). Using lz4 means that the main image section (all data other than header and bitmap) are stored in a compressed state. N5 results: Boot image size: 8067128 -> 2827605 Decompression time 18.93ms Decompression rate: 426MB/s Patchoat is not currently supported since it maps the source image directly. In order to support compressed images we would need to recompress the output image and then write it back out to a file. Also there are not many cases where we would want to patch a compressed image since they are going to be dirty memory when uncompressed anyways. Might as well just patch as we are loading.

Reduce memory used by CompiledMethods. Use LengthPrefixedArray<>s instead of SwapVector<>s to store CompiledMethod data and get rid of the unnecessary members of CompiledMethod to reduce dex2oat memory usage. Refactor the deduplication from CompilerDriver to a new class. Use HashSet<> instead of std::set<> for the DedupeSet<> to further decrease the memory usage and improve performance. This reduces the dex2oat memory usage when compiling boot image on Nexus 5 (with Optimizing, -j1) by ~6.75MiB (5%). This also reduces the compile time by ~2.2% (~1.6% dex2oat time; with Optimizing, without -j). Change-Id: I974f1f5e58350de2bf487a2bca3907fa05fb80ea

Optimizing: Determine invoke-static/-direct dispatch early. Determine the dispatch type of invoke-static/-direct in a special pass right after the type inference. This allows the inliner to pass the "needs dex cache" check and inline more. It also allows the code generator to avoid requesting a register location for the ArtMethod* for kDexCachePcRelative and direct methods. The supported dispatch check handles also situations that the CompilerDriver currently doesn't allow. The cleanup of the CompilerDriver and required changes to Quick will come in a separate change.

Use induction variable range analysis in BCE (statically). Rationale: Finally!

Move DWARF related code in ElfWriter to its own file. This is purely for organisation. The DWARF related code is becoming more complex and I do not want to keep mixing it with the ElfWriter. The ElfWriter probably should not be dealing with the fine details of DWARF generation. I intend to do much more work on DWARF in the future so this situatuion would only get worse as the code grows. The code could also use some refactoring and splitting. However, I have mostly just moved it in this CL. Change-Id: I6e3401a2b745ddf991b440ad7899ad7d4b921be6

ART: Boolean simplifier The optimization recognizes the negation pattern generated by 'javac' and replaces it with a single condition. To this end, boolean values are now consistently assumed to be represented by an integer. This is a first optimization which deletes blocks from the HGraph and does so by replacing the corresponding entries with null. Hence, existing code can continue indexing the list of blocks with the block ID, but must check for null when iterating over the list. Change-Id: I7779da69cfa925c6521938ad0bcc11bc52335583

Add JIT 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

Rewrite GVN's field id and field type handling. Create a helper unit for dex insn classification and cache dex field type (as encoded in the insn) in the MirFieldInfo. Use this for cleanup and a few additional DCHECKs. Change the GVN's field id to match the field lowering info index (MIR::meta::{i,s}field_lowering_info), except where multiple indexes refer to the same field and we use the lowest of the applicable indexes. Use the MirMethodInfo from MIRGraph to retrieve field type for GVN using this index. This slightly reduces GVN compilation time and prepares for further compilation time improvements.

dex2oat: Pack likely-dirty objects together when generating the boot image This introduces a new algorithm into image writer which "bins" objects by how likely they are to be dirtied at runtime. Objects in the same bin are placed contiguously in memory (i.e. into the same page). We try to tune the bin selection based on how clean or how dirty the object will likely be at runtime. As-is, this saves about 150KB per-process (private-dirty pages) and 700KB in zygote (shared-dirty). There is still about 800KB of objects that are clean but located in dirty pages, so with more analysis we can tune the bin selection and get even more memory savings.

Multilib ART host. Build ART for the host as a multilib project with dalvikvm32 and dalvikvm64 running as 32 or 64-bit repsectfully. Note, currently multilib host builds are not the default, you make the so by setting BUILD_HOST_64bit=1. Extend tests to execute in both 32 and 64-bit modes. By default both 32 and 64-bit tests are run, add 32 or 64 to the end of a test name to run it in purely that flavor. Given the extra spam, modify oat tests to only generate console output when the test fails. Change the test harness so that common commands are run when a test should be skipped, when it passes or when it fails. Use these commands to generate a summary of passing, skipped and failing tests. Tests will be skipped if they are known to be broken or if a test has already failed. Setting the variable TEST_ART_KEEP_GOING=true will force working tests not to be skipped. In this change all tests running on the optimizing compiler are marked broken due to breakages running them in a multilib environment. Break apart Android.common.mk into its constituent parts, along with other pieces of reorganization. Stylistic nit, we refer to make rule targets as targets thereby overloading the term target. While consistent with make's terminology, its confusing with the Android notion of target. I've switched to just calling targets rules to avoid confusion in host tests.

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

Thumb2 assembler for JNI compiler and optimizing compiler 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.

Rewrite BitVector index iterator. The BitVector::Iterator was not iterating over the bits but rather over indexes of the set bits. Therefore, we rename it to IndexIterator and provide a BitVector::Indexes() to get a container-style interface with begin() and end() for range based for loops. Also, simplify InsertPhiNodes where the tmp_blocks isn't needed since the phi_nodes and input_blocks cannot lose any blocks in subsequent iterations, so we can do the Union() directly in those bit vectors and we need to repeat the loop only if we have new input_blocks, rather than on phi_nodes change. And move the temporary bit vectors to scoped arena. Change-Id: I6cb87a2f60724eeef67c6aaa34b36ed5acde6d43

AArch64: Change arm64 backend to produce A64 code. The arm backend clone is changed to produce A64 code. At the moment this backend can only compile simple methods (both leaf and non-leaf). Most of the work on the assembler (assembler_arm64.cc) has been done. Some work on the LIR generation layer (functions such as OpRegRegImm & friends) is still necessary. The register allocator still needs to be adapted to the A64 instruction set (it is mostly unchanged from the arm backend). Offsets for helpers in gen_invoke.cc still need to be changed to work on 64-bit. Change-Id: I388f99eeb832857981c7d9d5cb5b71af64a4b921

Use trampolines for calls to helpers 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

Added pass framework The patch adds a Middle-End pass system and normalizes the current passes into the pass framework. Passes have: - A start, work, and end functions. - A gate to determine to apply the pass. - Can provide a CFG dump folder. mir_dataflow.cc, mir_graph.cc, mir_optimization.cc, ssa_transformation.cc: - Changed due to moving code into bb_optimizations.cc. - Moved certain functions from private to public due to needed from the passes. pass.cc, pass.h: - Pass base class pass_driver.cc, pass_driver.h: - The pass driver implementation. frontend.cc: - Replace the function calls to the passes with the pass driver.

Move compiler code out of method verifier. We want to detect small methods for inlining at the end of the method verification. Instead of adding more compiler code to the runtime, we create a callback from the runtime into the compiler, so that we can keep the code there. Additionally, we move the compiler-related code that was already in the method verifier to the compiler since it doesn't really belong to the runtime in the first place.

Get rid of platform-specific method inliners. The DexFileToMethodInlinerMap dependency on CompilerDriver and its instruction set makes it impossible to implement verification-time checking for methods we want to inline. Therefore, we get rid of the platform-specific method inliners and rely on the backend's existing ability to recognize when it can actually emit an intrinsic function.

Rewrite intrinsics detection. Intrinsic methods should be treated as a special case of inline methods. They should be detected early and used to guide other optimizations. This CL rewrites the intrinsics detection so that it can be moved to any compilation phase. Change-Id: I4424a6a869bd98b9c478953c9e3bcaf1c6de2b33

Inflate contended lock word by suspending owner. Bug 6961405. Don't inflate monitors for Notify and NotifyAll. Tidy lock word, handle recursive lock case alongside unlocked case and move assembly out of line (except for ARM quick). Also handle null in out-of-line assembly as the test is quick and the enter/exit code is already a safepoint. To gain ownership of a monitor on behalf of another thread, monitor contenders must not hold the monitor_lock_, so they wait on a condition variable. Reduce size of per mutex contention log. Be consistent in calling thin lock thread ids just thread ids. Fix potential thread death races caused by the use of FindThreadByThreadId, make it invariant that returned threads are either self or suspended now. Code size reduction on ARM boot.oat 0.2%. Old nexus 7 speedup 0.25%, new nexus 7 speedup 1.4%, nexus 10 speedup 2.24%, nexus 4 speedup 2.09% on DeltaBlue. Change-Id: Id52558b914f160d9c8578fdd7fc8199a9598576a

Multi threaded hashed deduplication during compilation. Moved deduplication to be in the compiler driver instead of oat writer. This enables deduplication to be performed on multiple threads.

Entry point clean up. Create set of entry points needed for image methods to avoid fix-up at load time: - interpreter - bridge to interpreter, bridge to compiled code - jni - dlsym lookup - quick - resolution and bridge to interpreter - portable - resolution and bridge to interpreter Fix JNI work around to use JNI work around argument rewriting code that'd been accidentally disabled. Remove abstact method error stub, use interpreter bridge instead. Consolidate trampoline (previously stub) generation in generic helper. Simplify trampolines to jump directly into assembly code, keeps stack crawlable. Dex: replace use of int with ThreadOffset for values that are thread offsets. Tidy entry point routines between interpreter, jni, quick and portable. Change-Id: I52a7c2bbb1b7e0ff8a3c3100b774212309d0828e (cherry picked from commit 848871b4d8481229c32e0d048a9856e5a9a17ef9)

Compilation filter This CL introduces a static compilation filter mechanism intended to allow us to reduce compilation time and space requirements until we have a profiling mechanism in place. It supports 5 modes of filtering: o interpret-only (compile nothing) o deferred-compilation (compile only those methods believe to be compute-intensive) o space (optimized for space) o balanced (best return on space investment) o speed (compile everything) A future CL will allow the default filtering mode to be set via system property. For now, you can pass it in via command line as follows: dalvikvm -compiler-filter:[interpret-only|defer-compilation| space|balanced|speed] or dex2oat --runtime-arg -compiler-filter:[one of the above modes] Creating a file named art/SMALL_ART will force the filter default to interpret-only. Later on we'll move this capability to a persistent system property. or modify kDefaultCompilerFilter in runtime.h It also changes the compiler driver to allow the compilers to decline to compile a method by return NULL.
