Hi Kiyo, At the moment we are trying to first pass all the jitBasic test cases. We updated the jit-arm.def to emit VFP instructions instead of VPA and made some other temporary changes related to EABI. We've not passed all jitBasic test cases yet. Will keep you posted. Note: we use gcc 4.1.1, kernel 2.6.17. At the moment Kaffe only emits FPA instructions instead of VFP. I assume your target uses FPA ?
