Dalvik JIT compiler on Linux X86 or Mac build

As I'开发者_如何转开发ve heard from Google IO 2010 session, Dalvik JIT compiler just support ARM processor. Do this mean my own build of Android source on Linux X86 or Mac OS X can not support JIT compiler?

Should I use some target board with ARM processor to test Dalvik JIT compiler?

Thanks!

I checked about it by myself from Linux emulator. JIT is working with WITH_JIT=true build option. Also, JIT also useful even on the emulation mode. Linpack shows about 2x more performance gain with JIT.

I checked out in latest Android source tree, and there is no x86 codegen there. That means you can only execute JIT on ARM hardware.
