* Add support for UXTB16 to the disassembler * Add encoding of the UXTB16 instruction to the Pixelflinger JIT. Introducing the UXTB16 instruction allows removal of some masking code, and is beneficial from a pipeline point of view - lots of UXTB16 followed by MUL sequences. Also, further rescheduling and use of SMULWB brings extra performance improvements. * Use UXTB16 in bilinear filtered texturing Uses UXTB16 to extract channels for SIMD operations, rather than creating and ANDing with masks. Saves a register and is faster on A8, as UXTB16 result can feed into first stage of multiply, unlike AND. Also, used SMULWB rather than SMULBB, which allows removal of MOVs used to rescale results. Code has been scheduled for A8 pipeline, specifically aiming to allow multiplies to issue in pipeline 0, for efficient dual issue operation. Testing on SpriteMethodTest (http://code.google.com/p/apps-for-android/) gives 8% improvement (12.7 vs. 13.7 fps.) SMULBB to SMULWB trick could be used in <v6 code path, but this hasn't been implemented. |

The system/ directory is intended for pieces of the world that are the core of the embedded linux platform at the heart of Android. These essential bits are required for basic booting, operation, and debugging. They should not depend on libraries outside of system/... (some of them do currently -- they need to be updated or changed) and they should not be required for the simulator build. The license for all these pieces should be clean (Apache2, BSD, or MIT). Currently system/bluetooth/... and system/extra/... have some pieces with GPL/LGPL licensed code. Assorted Issues: - pppd depends on libutils for logging - pppd depends on libcrypt/libcrypto - init, linker, debuggerd, toolbox, usbd depend on libcutils - should probably rename bionic to libc
