      "message": "Quickening support.\n\nThis CL adds quickening support for methods which are interpreted at runtime.\n\nThis CL introduces a DEX-to-DEX compiler. A method is now compiled in one of\nthe two following modes:\n- Native compilation: the method is compiled by the Quick or Portable backends.\nAt runtime, the generated native target-dependent code is executed.\n- DEX-to-DEX compilation: the method is executed by the interpreter at runtime.\nIts DEX code is compiled so some instructions can be replaced by special\ninstructions only valid at runtime. No native code is generated.\n\nThe quickening adds special instructions to improve runtime performance. They\nare \"-quick\" versions of the following instructions:\n- iget/iput\n- iget-wide/iput-wide\n- iget-object/iput-object\n- invoke-virtual/range.\n\nThese special instructions cannot be treated by the verifier since they lose\nthe field/method index referencing the field/method being accessed/invoked.\nTo prevent this, the DEX-to-DEX compiler is run only on methods of preverified\nclasses (without verification error at compilation time).\n\nThe DEX-to-DEX compiler implements quickening support using the CompilerDriver\ninterface like the native compiler does (Quick or Portable backends).\nTo replace instructions, the DEX-to-DEX compiler must be able to modify the\nmmapped DEX file. Since it can be read-only protected, the DEX-to-DEX compiler\nmust be able to temporarily change its protection to read-write mmapped file.\nTo achieve this, this CL adds support for changing DEX file protection with\nDexFile::EnableWrite and DexFile::DisableWrite methods. Besides, it also adds\na dedicated lock (DexFile::modification_lock) to ensure thread-safety and avoid\nconcurrent DEX file protection change (from a parallel DEX-to-DEX compiler on\nthe same DEX file).\n\nChange-Id: Iaafd103b9766810d7fc94a2c424a8fafba66e26a\n"

      "message": "Compiler: Spring cleaning\n\nSignificant restructuring of the Quick compiler to break out the\ncommon frontend more cleanly.  Additional C++\u0027ification.\n\nThe goal is to move from the monolithic structure of the old\nJIT towards a more modular model in which components - in\nparticular the compiler backend - can be replaced.  This CL\nfocuses on moving MIR-related data from the CompilationUnit\nstruct into a new MIRGraph class.  The next CL will isolate all\nLIR-related data and code down into the Quick backend.\n\nThis change will happen in multiple steps, and may look uglier\nbefore it starts looking better.\n\nAmong the changes:\n\n   o Moved all mir-related fields from CompilationUnit to new\n     MirGraph class.\n\n   o Moved the register promotion stuff into the Quick backend.\n\n   o Deleted the GBC to LIR conversion code.\n\n   o Replaced with old C-style function pointer dataflow analysis\n     dispatcher with a basic block iterator class.\n\n   o Renamed some files to make the name more consistent with what\n     the code actually does.\n\n   o Added the foundation for future inlining support.\n\n   o Stripped out the remains of the old fingerprinting mechanism.\n\nChange-Id: I6c30facc642f8084b1c7b2075cf7014de387aa56\n"

The Iceland option is temporary, and will go away once\nwe combine with Portable.  The Quick variants are with\nand without GBC conversion.  In time, those will converge to a\nsingle option.\n\nAll uses of \"#if defined(ART_USE_QUICK_COMPILER)\" are eliminated.  All\nprevious uses in the Quick compiler have been converted to runtime\ntests.  On the llvm side, ART_USE_QUICK_COMPILER was previously\nused to differentiate between Portable and Iceland builds.  Those\nusages have been replaced with ART_USE_PORTABLE_COMPILER, and in\na following CL will also be converted to run-time tests.\n\nAs of this CL, we\u0027re still generating separate libraries for\nQuick and Portable/Iceland.  Next up is elminating the target-specific\nlibraries for Quick-arm, Quick-x86 and Quick-mips.  Once that is\ncomplete, we will consoldate Quick and Portable into a single build.\n\nTo build either Iceland or Portable, touch USE_PORTABLE_COMPILER or\nUSE_LLVM_COMPILER as usual.  Otherwise, the build will default\nto Quick (non-GBC).\n\nChange-Id: Ic86c56f51710c9b06d4430b71a429ae12903cc47\n"
