2014-07-04Do not attempt to compile on architectures we do not support.Nicolas Geoffray
Change-Id: I431edff0a753a7fa37c79bdf7ab918d6747667a4
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
2014-06-25Revert "Re-enable tests with the optimizing compiler."Nicolas Geoffray

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.

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.

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.

2014-05-19Build live ranges in preparation for register allocation.Nicolas Geoffray
Change-Id: I7ae24afaa4e49276136bf34f4ba7d62db7f28c01
2014-05-14Add a compilation tracing mechanism to the new compiler.Nicolas Geoffray
Code mostly imported from: https://android-review.googlesource.com/#/c/81653/. Change-Id: I150fe942be0fb270e03fabb19032180f7a065d13
2014-05-13Add loop recognition and CFG simplifications in new compiler.Nicolas Geoffray
We do three simplifications: - Split critical edges, for code generation from SSA (new). - Ensure one back edge per loop, to simplify loop recognition (new). - Ensure only one pre header for a loop, to simplify SSA creation (existing). Change-Id: I9bfccd4b236a00486a261078627b091c8a68be33
2014-05-07Merge "Build live-in, live-out and kill sets for each block."Nicolas Geoffray
2014-05-07Build live-in, live-out and kill sets for each block.Nicolas Geoffray
This information will be used when computing live ranges of instructions. Change-Id: I345ee833c1ccb4a8e725c7976453f6d58d350d74
2014-05-06Give Compiler a back reference to the driver.Ian Rogers
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.

2014-04-28Add a Transform to SSA phase to the optimizing compiler.Nicolas Geoffray

2014-04-04Use trampolines for calls to helpersDave Allison
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
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
2014-03-19Run Java tests with the optimizing compiler.Nicolas Geoffray
Also fix a vector.reserve -> vector.resize braino, and build a GC map that dex2oat expects. Change-Id: I6acf2f90a4c32f90b79bf7709bf2e43931b98757
2014-03-18Plug new optimizing compiler in compilation pipeline.Nicolas Geoffray
Also rename accessors to ART's conventions. Change-Id: I344807055b98aa4b27215704ec362191464acecc
2014-03-13Add command line support for enabling the optimizing compiler.Nicolas Geoffray
Also run tests with the optimizing compiler enabled when the file art/USE_OPTIMIZING_COMPILER is present. Change-Id: Ibc33eed62a43547bc3b9fe786d014c0d81b5add8
