Hi all,The generic rtx cost table was written with AArch32 cores in mind. It would be a better idea to use the Cortex-A57 costs for the generic CPU in aarch64. That way we schedule for the Cortex-A53 and do instruction selection for the Cortex-A57. Since generic is the default CPU, this patch can change default code generation but is highly unlikely to affect correctness (unless it exposes latent bugs) since it only affects instruction selection. Tested aarch64-none-elf on a model with no regressions. Is it ok for trunk now or shall we wait for stage1?

I think this is the right direction to go, and as such I'd prefer that we did it for 4.9.
Please give the RMs 24 hours to comment. But otherwise OK. R.
