* Remove type conversion nodes converting to the same type.Nicolas Geoffray2014-12-011-2/+2
| | | | | | | When optimizing, we ensure these conversions do not reach the code generators. When not optimizing, we cannot get such situations. Change-Id: I717247c957667675dc261183019c88efa3a38452
* Don't use CanHoldArm in the code generator.Nicolas Geoffray2014-11-281-11/+11
| | | | | | | | CanHoldArm was ARM32 specific. Instead use a virtual Assembler::ShifterOperandCanHold that both thumb2 and arm32 implement. Change-Id: I33794a93caf02ee5d78d32a8471d9fd6fe4f0a00
* Add support for long-to-float in the optimizing compiler.Roland Levillain2014-11-271-11/+58
| | | | | | | | | | | | - Add support for the long-to-float Dex instruction in the optimizing compiler. - Have art::x86_64::X86_64Assembler::cvtsi2ss work with 64-bit operands. - Generate x86, x86-64 and ARM (but not ARM64) code for long to float HTypeConversion nodes. - Add related tests to test/422-type-conversion.

| | | | | | | | | | | | | | | | Replace Location::As<T>() with two method methods (Location::AsRegister<T>() and Location::AsFpuRegister<T>()) checking the kind of the location (register). Change-Id: I22b4abee1a124b684becd2dc1caf33652b911070
* | Fix Move64 by using ParallelMoves.Nicolas Geoffray2014-11-271-22/+30
|/ | | | | | | Destination and source might overlap in a Move64, so we have to use a parallel move resolver. Change-Id: Ica6c72d91ab8e2e2ee4661b211ac1ee8f054b9ef

* Revert "[optimizing compiler] Add CMP{L,G}_{FLOAT,DOUBLE}"Calin Juravle2014-11-261-49/+22
| | | | | | | | Fails on arm due to missing vmrs op after vcmp. I revert this instead of pushing the fix because I don't understand yet why it compiles with run-test but not with dex2oat. This reverts commit fd861249f31ab360c12dd1ffb131d50f02b0bfc6. Change-Id: Idc2d30f6a0f39ddd3596aa18a532ae90f8aaf62f

* | Move dexCacheStrings from ArtMethod to ClassMathieu Chartier2014-11-251-2/+2
|/ | | | | | | | | | | | Adds one load for const strings which are not direct. Saves >= 60KB of memory avg per app. Image size: -350KB. Bug: 17643507 Change-Id: I2d1a3253d9de09682be9bc6b420a29513d592cc8 (cherry picked from commit f521f423b66e952f746885dd9f6cf8ef2788955d)

* Consistently use k{InstructionSet}WordSize.Nicolas Geoffray2014-11-191-3/+3
| | | | | | | | These constants were defined prior to k{InstructionSet}PointerSize. So use them consistently in optimizing as a first step. We can discuss whether we should remove them in a second step. Change-Id: If129de1a3bb8b65f8d9c816a8ad466815fb202e6
* Change 64 bit ArtMethod fields to be pointer sizedMathieu Chartier2014-11-181-3/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | Changed the 64 bit entrypoint and gc map fields in ArtMethod to be pointer sized. This saves a large amount of memory on 32 bit systems. Reduces ArtMethod size by 16 bytes on 32 bit. Total number of ArtMethod on low memory mako: 169957 Image size: 49203 methods -> 787248 image size reduction. Zygote space size: 1070 methods -> 17120 size reduction. App methods: ~120k -> 2 MB savings. Savings per app on low memory mako: 125K+ per app (less active apps -> more image methods per app). Savings depend on how often the shared methods are on dirty pages vs shared. TODO in another CL, delete gc map field from ArtMethod since we should be able to get it from the Oat method header. Bug: 17643507 Change-Id: Ie9508f05907a9f693882d4d32a564460bf273ee8 (cherry picked from commit e832e64a7e82d7f72aedbd7d798fb929d458ee8f)
