SPECfp wouldn't be a valid test at all, considering the "developmental"
nature of the current x86 translator. SPECint would be almost fair,
especially if native binaries are compiled with gcc 2.8.1 and not 2.9.x.
It would be really fair if it also didn't make use of type "long": x86
compilers use 32 bits for it, while VP uses 64 and thus has to emulate
such arithmetic in software (which makes things slower).
Nothing or noone prevents you from porting any benchmarks, anyway.
