* Dalvik: Add hardware vfp support for OP_LONG_TO_DOUBLE in JITSerban Constantinescu2013-12-191-0/+12
| | | | | | | | | The following patch adds hardware vfp support for OP_LONG_TO_DOUBLE in the JIT. Previously this opcode was implemented using one of gcc's builtin helpers. Change-Id: I3c88b2a527dea99dcefdb34be6695e75993da73e Signed-off-by: Serban Constantinescu <serban.constantinescu@arm.com>
* Dalvik: Add sdiv support in the JITSerban Constantinescu2013-12-191-0/+15
| | | | | | | | | | | | | | | | | | | | This patch adds hardware divide support in the JIT side of dalvik. This operation is supported on new armv7 cpus such as A15 or A7. The following opcodes are enabled and will generate code based using SDIV instruction: OP_DIV_INT OP_DIV_INT_2ADDR OP_REM_INT OP_REM_INT_2ADDR OP_DIV_INT_LIT16 OP_DIV_INT_LIT8 OP_REM_INT_LIT16 OP_REM_INT_LIT8 Change-Id: I2b2f9f337f13b5c794df951c4929b6ca0ad583c4 Signed-off-by: Serban Constantinescu <serban.constantinescu@arm.com>

| * JIT: Use rsb and shift in easy multiply.Anders O Nilsson2013-06-141-0/+5
| | | | | | | | | | | | | | | | | | | | | | For easy multiplication using reverse subtract (when lit is 2^n-1) use the barrel shifter for rsb. This improves arithmetic performance for code executing in Dalvik. E.g String.hashCode. Change-Id: Ifb086dcec344b30fd3e392ac21d508b43e820cdc Signed-off-by: Patrik Ryd <patrik.ryd@stericsson.com>
| * JIT: Performance fix for const doublesbuzbee2012-11-301-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | Some recent Arm processors take a performance hit when creating a floating point double by loading it as a pair of singles. Legacy code to support soft floating point doubles as a pair of core registers loaded double immediates in this way. With the CL, we handle double immediates as a single unit. (cherry-pick of c8129911e598ad0ca8d7b31012444ab6ce8bce45.) Change-Id: Ic1512e34bfd233a6f5ffd58ce843965adbbad875
* | JIT tuning; set cache size on command linebuzbee2013-05-231-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The tuning knobs for triggering trace compilation for the JIT had not been revisited for several years. In that time, the working set of some applications have significantly increased, leading to frequent cache overlows & flushes. This CL adds the ability to set the maximum size of the JIT's cache on the command line, and we expect to use different settings depending on device configuration (rule of thumb: 1K for each 1M for system RAM, with 2M limit). Additionally, the trace compilation trigger has been tightened to limit the compilation of cold traces. Change-Id: Ice22c5d9d46a93e465c57dd83f50ca3912f1672e

* [X86] X86 trace JIT compiler supportDong-Yuan Chen2012-07-201-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch provides a fully functional x86 trace JIT compiler for Dalvik VM. It is built on top of the existing x86 fast interpreter with bug fixes and needed extension to support trace JIT interface. The x86 trace JIT code generator was developed independent of the existing template-based code generator and thus does not share exactly the same infrastructure. Included in this patch are: * Deprecated and removed the x86-atom fast interpreter that is no longer functional since ICS. * Augmented x86 fast interpreter to provide interfaces for x86 trace JIT compiler. * Added x86 trace JIT code generator with full JDWP debugging support. * Method JIT and self-verification mode are not supported. The x86 code generator uses the x86 instruction encoder/decoder library from the Apache Harmony project. Additional wrapper extension and bug fixes were added to support the x86 trace JIT code generator. The x86 instruction encoder/decoder is embedded inside the x86 code generator under the libenc subdirectory.
