[kaffe] Anyone working on ARM VFP + EABI support ?

[Ronald Sloot]

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 ?
