Dalvik: Add hardware support for OP_LONG_TO_DOUBLE in the interpreter

2013-12-19T18:31:52+00:00

The following patch adds hardware vfp support for OP_LONG_TO_DOUBLE
in the interpreter. Previously this opcode was implemented using one of
gcc's builtin helpers.

Dalvik: Add sdiv support in the interpreter

2013-12-19T18:31:50+00:00

This patch adds hardware divide support in the interpreter side of
dalvik. This operation is supported on new armv7 cpus such as A15 or A7.

Opcodes added:
    OP_DIV_INT
    OP_DIV_INT_2ADDR
    OP_DIV_INT_LIT16
    OP_DIV_INT_LIT8
    OP_REM_INT
    OP_REM_INT_2ADDR
    OP_REM_INT_LIT16
    OP_REM_INT_LIT8

Merge "Dalvik: DMB Optimisation"

2013-11-14T01:12:35+00:00

Move dalvik's MIPS code off old kernel headers.

2013-11-14T00:06:53+00:00

I suspect this was actually my fault; I think MIPS originally
explicitly defined all these constants themselves.

Dalvik: DMB Optimisation

2013-11-12T17:35:47+00:00

Replaces use of 'dmb' and 'dmb st' with inner-shareable versions.
This should improve performance in certain cases without harming
correctness.

[MIPS] Optimize opcodes to avoid bubble in pipeline.

2013-10-25T21:27:57+00:00

Possible bubbles between fetch(ldr) and extract(and).
Excute subsequent instruction(s) in between the bubble by
reordering instructions

Revert "Remove some of the x86 libdvm.so text relocations."

2013-08-09T18:41:42+00:00

This reverts commit 469e580f6a18c00a3c356ae3898aa8d143736016.

Although dalvik/tests/run-all-tests passed on an emulator after this change, starting a host VM crashes in dvmAsmInstructionStartCode, which is highly suspicious.

Since this change didn't actually solve my problem (I'd need to remove all text relocations to make the linker happy with the x86 libdvm.so, so it would stop warning, so the tests would stop failing because the output doesn't match the golden output), I'm just going to revert and leave it for now.

[x86] Fix errors with WITH_JIT_TUNING defined

2013-03-29T21:05:18+00:00

This patch makes the necessary changes to pass on correct information to
dvmBumpNoChain, so that WITH_JIT_TUNING flag can be enabled for x86 codegen
