2014-09-15Revert "Implement suspend checks in new compiler."Nicolas Geoffray
This reverts commit 6fbce029fba3ed5da6c36017754ed408e6bcb632. Change-Id: Ia915c27873b021e658a10212e559095dfc91284e
2014-09-15Implement suspend checks in new compiler.Nicolas Geoffray
For simplicity, they are currently placed on all (dex-level) back edges, and at method entry. Change-Id: I6e833e244d559dd788c69727e22fe40aff5b3435
2014-09-08Runtime support for the new stack maps for the opt compiler.Nicolas Geoffray
Now most of the methods supported by the compiler can be optimized, instead of using the baseline. Change-Id: I80ab36a34913fa4e7dd576c7bf55af63594dc1fa
2014-08-13Reduce stack usage for overflow checksDave Allison
This reduces the stack space reserved for overflow checks to 12K, split into an 8K gap and a 4K protected region. GC needs over 8K when running in a stack overflow situation. Also prevents signal runaway by detecting a signal inside code that resulted from a signal handler invokation. And adds a max signal count to the SignalTest to prevent it running forever. Also reduces the number of iterations for the InterfaceTest as this was taking (almost) forever with the --trace option on run-test. Bug: 15435566 Change-Id: Id4fd46f22d52d42a9eb431ca07948673e8fda694
2014-07-28Implement array get and array put in optimizing.Nicolas Geoffray
Also fix a couple of assembler/disassembler issues. Change-Id: I705c8572988c1a9c4df3172b304678529636d5f6
2014-07-22Stack overflow checks and NPE checks for optimizing.Nicolas Geoffray
Change-Id: I59e97448bf29778769b79b51ee4ea43f43493d96
2014-07-21Add write barriers to optimizing compiler.Nicolas Geoffray
Change-Id: I43a40954757f51d49782e70bc28f7c314d6dbe17
2014-07-21Add assembly operations with constants in optimizing compiler.Nicolas Geoffray
Change-Id: I5bcc35ab50d4457186effef5592a75d7f4e5b65f
2014-07-16Use the thumb2 assembler for the optimizing compiler.Nicolas Geoffray
Change-Id: I2b058f4433504dc3299c06f5cb0b5ab12f34aa82
2014-07-15Fix a braino in the stack layout.Nicolas Geoffray
Also do some refactoring to have this code be just in CodeGenerator. Change-Id: I88de109889138af8d60027973c12a64bee813cb7
2014-07-14Support fields in optimizing compiler.Nicolas Geoffray
- Required support for temporaries, to be only used by baseline compiler. - Also fixed a few invalid assumptions around locations and instructions that don't need materialization. These instructions should not have an Out. Change-Id: Idc4a30dd95dd18015137300d36bec55fc024cf62
2014-07-02Support longs in the register allocator for x86_64.Nicolas Geoffray
Change-Id: I7fb6dfb761bc5cf9e5705682032855a0a70ca867
2014-06-26Re-enable tests with the optimizing compiler.Nicolas Geoffray
Tests run ok on my host/target. I reverted the move to using thumb2, because tests were crashing. But I could not reproduce file limits issues. Make SignalTest as crashing for optimizing. We need to implement stack overflow checks. Change-Id: Ieda575501eaf30af7aaa2c44e71544c9c467c24f
2014-06-24Add some more instruction support to optimizing compiler.Dave Allison
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
2014-06-13Add x86_64 support to the optimizing compiler.Nicolas Geoffray
Change-Id: I4462d9ae15be56c4a3dc1bd4d1c0c6548c1b94be
2014-06-12Enable the register allocator on ARM.Nicolas Geoffray
- Also fixes a few bugs/wrong assumptions in code not hit by x86. - We need to differentiate between moves due to connecting siblings within a block, and moves due to control flow resolution. Change-Id: Idd05cf138a71c8f36f5531c473de613c0166fe38
2014-06-12Final CL to enable register allocation on x86.Nicolas Geoffray
This CL implements: 1) Resolution after allocation: connecting the locations allocated to an interval within a block and between blocks. 2) Handling of fixed registers: some instructions require inputs/output to be at a specific location, and the allocator needs to deal with them in a special way. 3) ParallelMoveResolver::EmitNativeCode for x86. Change-Id: I0da6bd7eb66877987148b87c3be6a983b4e3f858
2014-06-10Plug code generator into liveness analysis.Nicolas Geoffray
Also implement spill slot support. Change-Id: If5e28811e9fbbf3842a258772c633318a2f4fafc
2014-05-26Add a linear scan register allocator to the optimizing compiler.Nicolas Geoffray
This is a "by-the-book" implementation. It currently only deals with allocating registers, with no hint optimizations. The changes remaining to make it functional are: - Allocate spill slots. - Resolution and placements of Move instructions. - Connect it to the code generator. Change-Id: Ie0b2f6ba1b98da85425be721ce4afecd6b4012a4
2014-05-23Import Dart's parallel move resolver.Nicolas Geoffray
And write a few tests while at it. A parallel move resolver will be needed for performing multiple moves that are conceptually parallel, for example moves at a block exit that branches to a block with phi nodes. Change-Id: Ib95b247b4fc3f2c2fcab3b8c8d032abbd6104cd7
2014-04-29Force inlining on trivial accessors.Ian Rogers
Make volatility for GetFieldObject a template parameter. Move some trivial mirror::String routines to a -inl.h. Bug: 14285442 Change-Id: Ie23b11d4f18cb15a62c3bbb42837a8aaf6b68f92
2014-04-29Setup policies for register allocation.Nicolas Geoffray
Change-Id: I857e77530fca3e2fb872fc142a916af1b48400dc
2014-04-28Add a Transform to SSA phase to the optimizing compiler.Nicolas Geoffray
Change-Id: Ia9700756a0396d797a00b529896487d52c989329
2014-04-17Code cleanup in preparation for x64 backend.Nicolas Geoffray
- Use InvokeDexCallingConventionVisitor for setting up HParameterValues - Use kVregSize instead of kX86WordSize when dealing with virtual registers. Change-Id: Ia520223010194c70a3ff0ed659077f55cec4e7d8
2014-04-17Simplify HInvokeStatic code generation.Nicolas Geoffray
HPushArgument is not needed for now (but might be when we start optimizing). Also, calling convention for 64bits backend will require to know more about the argument than the argument's index. Therefore currently let HInvokeStatic setup the arguments, which is possible because arguments of a calls are virtual registers and not instructions. Change-Id: I8753ed6083aa083c5180ab53b436dc8de4f1fe31
2014-04-16Long support in optimizing compiler.Nicolas Geoffray
- Add stack locations to the Location class. - Change logic of parameter passing/setup by setting the location of such instructions the ones for the calling convention. Change-Id: I4730ad58732813dcb9c238f44f55dfc0baa18799
2014-04-08Test control flow instruction with optimizing compiler.Nicolas Geoffray
Add support for basic instructions to implement these tests. Change-Id: I3870bf9301599043b3511522bb49dc6364c9b4c0
2014-04-07Add support for taking parameters in optimizing compiler.Nicolas Geoffray
- Fix stack layout to mimic Quick's. - Implement some sub operations. Change-Id: I8cf75a4d29b662381a64f02c0bc61d859482fc4e
2014-04-04Use target-specific word instead of runtime word.Nicolas Geoffray
Change-Id: Ia11dc3cc520a1a5c7bd017013e5699af9570ce91
2014-04-04Add support for new-instance and invoke-direct.Nicolas Geoffray
Change-Id: I2daed646904f7711972a7da15d88be7573426932
2014-04-03Support passing arguments to invoke-static* instructions.Nicolas Geoffray
- Stop using the frame pointer for accessing locals. - Stop emulating a stack when doing code generation. Instead, rely on dex register model, where instructions only reference registers. Change-Id: Id51bd7d33ac430cb87a53c9f4b0c864eeb1006f9
2014-03-31Add support for adding two integers in optimizing compiler.Nicolas Geoffray
Change-Id: I5524e193cd07f2692a57c6b4f8069904471b2928
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
2014-03-18Plug new optimizing compiler in compilation pipeline.Nicolas Geoffray

2014-03-13More code generation for the optimizing compiler.Nicolas Geoffray
- Add HReturn instruction - Generate code for locals/if/return - Setup infrastructure for register allocation. Currently emulate a stack. Change-Id: Ib28c2dba80f6c526177ed9a7b09c0689ac8122fb
2014-03-10Add register support to the optimizing compiler.Nicolas Geoffray
Also make if take an input and build the use list for instructions. Change-Id: I1938cee7dce5bd4c66b259fa2b431d2c79b3cf82
2014-03-04Add codegen support to the optimizing compiler.Nicolas Geoffray
