I am afraid I don't have a choice but to use the latest gcc tool chain as I need EABI support. Yes, QEMU supports VFP (I am using QEMU before I switch to hardware) but the JITer does not emit VFP opcodes - it emits FPA (Floating Point Accelerator) opcodes which are not compatible. As far as I know ARM considers FPA to be obsolete and is not supported anymore by version 2 of the ABI for the ARM architecture.
