The adjusted vector costs give Falkor a reasonable boost inperformance for FPbenchmarks (both CPU2017 and CPU2006) and doesn't change INTbenchmarks that

OK for trunk?
OK if this is what works best for your subtarget.
I have pushed this for Luis since he is on holiday.

Thanks,
Siddhesh

Given this has a significant performance impact on Falkor and thechanges are very localized and specific to Falkor, it would be great tohave them on GCC 8. Would it be ok to push it?


Thanks,
Luis
